The red-cord man disappeared into the market crowd with the hunched shoulders of someone who had already begun rehearsing a lie for the next person he would meet. Gu Yanshu watched him go only once, then turned away before that glance could become obvious. Lin Qiren noticed the movement, but said nothing. T.A.R. noticed it too, though he looked as if he wanted to ask a question and disliked the answer before it was spoken.
The street remained noisy around them. A cart wheel hit a stone and bounced. A vendor called out prices in a tired voice. Two children ran past carrying a bundle of twine between them like it was a banner. To anyone watching from a distance, the danger from the drainage line had already become just another problem in Area 900, filed into the large category of things that would be dealt with later if they could not be ignored entirely.
Gu Yanshu did not believe in later.
He walked with the others back toward the inn by the long route, not because it was safer, but because the longer route gave him more time to notice which doors had opened after the incident and which had not. In this town, reactions arrived before confessions. One shopkeeper had already lowered his shutters halfway despite the hour. A guard at the corner had changed his stance from casual to watchful. Near the tea stall, an old woman who had not been there earlier now stood cleaning cups that were already clean.
That meant someone had begun hearing the right version of the story.
Lin Qiren spoke first.
"You sent him back with false information."
"Yes."
T.A.R. gave a short breath through his nose. "You make it sound ordinary."
"It is ordinary," Gu Yanshu said. "People survive by repeating words that are useful to them."
The girl glanced at him. "And if he tells Steward Ke the truth instead?"
Gu Yanshu looked ahead. "Then he will be killed before he can become a useful witness."
No one answered that immediately.
The truth was too plain to argue with. Area 900 was not the kind of place where invisible hands stayed invisible forever. If the red-cord man had spoken to the wrong person, if fear overtook him, if one detail in the story shifted too early, the thread could be cut before it led anywhere.
That was why Gu Yanshu had not given him a command. Commands were brittle. Fear was not. Fear could carry a person forward for several more steps if the path in front of them looked narrower than the path behind.
When they reached the inn, the owner was waiting by the counter with a look that suggested he had already decided not to ask questions and was merely enduring the cost of that decision. He handed Lin Qiren a small note without speaking. Lin Qiren opened it, frowned, and passed it to Gu Yanshu.
The note contained three words.
Lower records hall.
Nothing else.
T.A.R. crossed his arms. "That's convenient."
Gu Yanshu folded the paper and placed it on the table. "Too convenient."
The girl looked at the innkeeper. "Who brought it?"
The owner shook his head once. "No one I know."
That was almost certainly false, but false in a way that mattered. The note had been delivered by someone whose name the owner either did not want to repeat or had never been told. Either way, it meant the hall had already begun moving its own pieces before the town could fully settle around the earlier attack.
Lin Qiren leaned against the wall, eyes narrowed. "So now the hall wants us to come."
"Someone in it does," Gu Yanshu said.
T.A.R. frowned. "That sounds like a distinction you care about."
"It is."
The girl placed her hands lightly on the table. "Then tell us why."
Gu Yanshu did not answer at once. Instead he took the note back, held it under the lamp, and looked at the pressure of the ink. One side had been pressed harder than the other. That meant the writer had been standing when they wrote it or writing quickly while moving.
He said, "If Steward Ke is the one controlling permits and routes, he would not send a direct message unless he wanted us to think he was careless. That means either he is overconfident, or someone else is using him as a visible hand."
Lin Qiren said, "A mask."
"Yes."
T.A.R. looked mildly irritated. "You like masks."
"No. I like the thing behind them."
That answer made the room quiet for half a breath.
Then the girl asked, "What do you want us to do?"
Gu Yanshu lifted the note slightly. "We go where we are meant to look as if we were invited, but we do not go through the front."
Lin Qiren nodded once. "You want the back route."
"Yes."
T.A.R. gave a dry laugh. "Naturally."
By the time the sun began to lower, the four of them had split into different movements while remaining pointed toward the same place. Lin Qiren walked visibly through the market, allowing himself to be seen speaking with vendors and asking about missing routes and tunnel collapses. T.A.R. and the girl took the side alleys near the lower storage streets, where they could observe the hall workers without looking obvious. Gu Yanshu stayed farther back, moving through the edge paths where the drainage channels cut thin lines between buildings.
That was where he found the first pattern.
The people who worked near the lower records hall were not ordinary laborers. Several wore the same gray sash tied in a way too neat for city work. A pair of guards stood at the corner for too long without changing shifts. One man carried a stack of permit slips and looked over his shoulder twice before crossing an empty street. The hall itself was built low and narrow, its outer walls plain stone, its windows small and set high enough that no one could look directly inside from the road.
It wanted to look unimportant.
Which meant it mattered.
Gu Yanshu waited until dusk before speaking to anyone.
The first was a boy carrying ink bundles to the side entrance. He was perhaps thirteen, with hands stained black at the fingertips and the nervous attention of someone who had been trained to answer quickly. Gu Yanshu stepped into his path gently enough that the boy did not flinch.
"Who sends the ink?" he asked.
The boy stared. "The hall."
"That is not what I asked."
The boy swallowed. His eyes darted to the side. "Steward Ke's assistant."
"Name?"
The boy hesitated longer this time. "Ming Zhuo."
Gu Yanshu nodded slightly. "Does he always send you?"
"Yes."
"Does he always ask you to wait before entering?"
The boy blinked. "How did you know?"
Gu Yanshu did not answer. Instead he handed the boy a copper coin and let him continue on. The answer had been enough. People who were told to wait before entering a hall usually waited because someone inside wanted time to hide whatever should not be seen. Waiting was not caution. Waiting was staging.
He moved around the side wall and found a narrow drain opening near the rear alley. Water flowed through it too slowly for a functioning channel, which meant it was partly blocked by sediment or deliberately narrowed. He crouched and looked inside. There were fresh scrape marks on the stone, and the smell of blue powder lingered faintly in the dark.
T.A.R. appeared beside him a few moments later, silent enough that a lesser observer might have been startled.
"You found something," he said.
"Several things."
T.A.R. crouched too, peering into the drain. "Powder?"
"Yes."
"Same as before?"
"Likely."
He exhaled sharply. "Then someone here is still moving the same tools."
Gu Yanshu stood. "Not just moving them. Reusing them."
T.A.R. looked up. "That matters?"
"Very much."
He saw the confusion in T.A.R.'s face and went on, not out of kindness, but because T.A.R. was the kind of person who became dangerous when he understood too little. "If the same powder is used twice, the second time is never about the original attack. It is about what the first attack taught them."
T.A.R. frowned, then slowly straightened. "So the hall is learning."
"Yes."
"And from who?"
Gu Yanshu looked toward the hall.
"From us."
That answer settled on T.A.R. with visible weight. He went quiet after that, no longer pretending this was a simple town problem. The girl joined them soon after, having circled around the rear path with a stack of folded notices taken from a nearby post board.
She handed one to Gu Yanshu.
The notice was a permit update, ordinary on its face, but the route names had been altered. Two of the changes redirected cart traffic away from the lower drainage line and toward the old grain lane. That was a mistake for a functioning town. Grain lane had loose paving and too many blind corners. It would slow movement, cause delays, and make anyone carrying goods easy to monitor.
Or it would do all that if the route was supposed to be visible.
Gu Yanshu looked at the paper for a long time.
Lin Qiren returned at almost the same time, having walked a circuit around the central market and the outer stalls.
He did not waste words. "People are talking about the drainage attack in three different versions."
T.A.R. gave him a dry look. "That is normal."
"No," Lin Qiren said. "It is not. One version says the beast broke loose. One says it was lured out. One says the lower hall had already been warning people to avoid the north lane."
The girl's brows drew together. "So the hall is spreading the safest lie."
"Exactly," Lin Qiren said.
Gu Yanshu folded the permit notice and tucked it into his sleeve. "Which means someone wants the town calm, but not informed."
T.A.R. stared at him. "That sounds worse."
"It is worse."
The air between them tightened.
Then the side door of the hall opened.
A middle-aged man stepped out in a gray official robe with a ring of keys at his waist. His face was long and slightly drawn, with eyes that looked permanently tired of either lying or listening to lies. He stopped when he saw the group, then smiled a little too quickly.
"You are the visitors from the road?" he asked.
Lin Qiren answered before anyone else could. "Maybe."
The man's smile twitched. "I am Assistant Steward Ming Zhuo. If you have concerns about route restrictions, permit allocations, or the recent tunnel matter, you can submit your questions in writing."
That was clean. Too clean.
Gu Yanshu looked at the ring of keys.
One key on the ring was newer than the others.
He said, "Then we should submit them."
Ming Zhuo blinked. "Now?"
"Now."
The man hesitated for only a second too long. Then he stepped aside.
"Very well."
The inside of the lower records hall was cooler than the street and smelled of ink, wax, and old paper. Shelves lined the corridor in narrow rows, each one stacked with logs and route ledgers tied in red string. A lamp burned at the far table, where a clerk sat bent over documents with the tense concentration of someone who did not want to look up.
Ming Zhuo led them inward, his steps measured.
Gu Yanshu observed everything.
The fresh dust near the left shelf. The missing space on the permit rack. The way the clerk's hand stopped moving for one breath whenever the name "Steward Ke" was mentioned. The one newer key on Ming Zhuo's ring had a blue cord attached to the loop, the same shade as the powder from the drainage line.
Not proof.
Enough.
They reached a small office at the back where a narrow door stood closed. Ming Zhuo cleared his throat and turned to face them.
"Steward Ke is not in at the moment."
Lin Qiren crossed his arms. "Then why are we here?"
Ming Zhuo looked at Gu Yanshu briefly, then away again.
"Because," he said carefully, "someone left a report in the wrong tray, and it contained your names."
The room seemed to still.
T.A.R. swore under his breath.
The girl looked at Gu Yanshu.
Lin Qiren's hand shifted slightly toward his spear.
Gu Yanshu did not move.
Inside the office, beyond the narrow door, a faint sound came from the other side of the wood.
Not footsteps.
Not breathing.
Paper sliding across a desk.
Someone was listening.
And now they knew exactly whose attention had been brought to the lower records hall.The office fell into a heavy silence after the document closed in Gu Yanshu's hands.
Ming Zhuo did not breathe normally anymore. Each inhale came shallow and uneven, like a man standing too close to a cliff and suddenly realizing the ground beneath him might crumble. Steward Ke remained calm, but his stillness was not the stillness of peace; it was the stillness of someone watching a trap to see which animal stepped into it.
Lin Qiren shifted his weight slightly, the faint scrape of his boot against the stone floor echoing through the small room. T.A.R. leaned back against the wall, though his eyes never left Ming Zhuo. The girl stood quietly near the shelf, fingers resting lightly against the wood, listening more than watching.
Gu Yanshu placed the folded report back on the table.
He did not accuse anyone.
He did not ask any direct question.
Instead, he said, "These routes overlap too often."
Steward Ke's eyes sharpened.
"Yes."
"The blue powder shipments move through the same lanes as permit adjustments."
"Yes."
"And the storage keys change whenever a shipment arrives."
Steward Ke nodded once.
Ming Zhuo's hands began to tremble.
Gu Yanshu continued calmly, "That means the distribution network does not operate in secret. It operates inside official movement."
T.A.R. let out a quiet breath. "So the hall itself is part of it."
"Not the hall," Gu Yanshu said. "The structure of the hall."
Steward Ke's expression changed slightly, a faint hint of approval appearing.
"Explain."
Gu Yanshu rested his fingers lightly on the document.
"A network that hides completely is fragile. One mistake exposes everything. But a network that hides inside normal procedures becomes invisible because people stop looking at ordinary actions. Permit updates, route changes, storage keys, clerk reports… all of these become shields."
Lin Qiren nodded slowly. "Like hiding a knife in a toolbox."
"Yes."
The girl spoke softly, "And if one worker is exposed, the rest remain safe because the system continues functioning."
"Exactly."
Steward Ke crossed his arms.
"So what do you think of Ming Zhuo?"
The assistant steward flinched.
Gu Yanshu did not look at him.
"That depends."
"On what?"
"On whether he is a participant or a conduit."
Ming Zhuo suddenly spoke, voice shaking.
"I have done nothing wrong."
No one responded.
The silence forced him to continue.
"I only moved documents and updated permits. I never handled any powder or controlled any shipments. I only followed orders."
Steward Ke looked at him calmly.
"Whose orders?"
Ming Zhuo hesitated.
"I… I do not know."
T.A.R. scoffed quietly.
Lin Qiren's gaze remained steady.
Gu Yanshu finally turned to look at Ming Zhuo.
"When did you receive the new key?"
Ming Zhuo blinked.
"A month ago."
"From whom?"
"Steward Ke."
Steward Ke shook his head.
"No."
Ming Zhuo froze.
The room tightened again.
Gu Yanshu spoke gently, "Think carefully."
Ming Zhuo swallowed.
"It… it was delivered through the records desk. I was told it was from Steward Ke's office."
"And you accepted it."
"Yes."
"Without verifying."
Ming Zhuo's voice dropped to a whisper.
"Yes."
Gu Yanshu nodded slightly.
"That means someone used authority to place a tool in your hand."
Ming Zhuo's knees weakened, and he grabbed the edge of the table to steady himself.
"I didn't know…"
Steward Ke watched him silently.
Gu Yanshu continued, voice steady and calm.
"You updated routes based on instructions."
"Yes."
"You stored documents based on instructions."
"Yes."
"You opened and closed storage rooms based on instructions."
"Yes."
"And every time, you believed you were doing your job."
Ming Zhuo nodded weakly.
Gu Yanshu turned back to Steward Ke.
"He is a conduit."
Steward Ke narrowed his eyes.
"Not a liar?"
"No."
"Not a traitor?"
"No."
"Not part of the network?"
Gu Yanshu paused.
Then he said, "He is part of it, but not knowingly."
Ming Zhuo looked like he might collapse.
Steward Ke sighed quietly.
"That is the worst kind."
T.A.R. frowned.
"Why?"
Steward Ke answered, "Because people like him can be used repeatedly without realizing it. They do not resist. They do not question. They simply continue working."
Lin Qiren spoke.
"So the real network is above him."
"Yes."
The girl asked softly, "Then why keep him alive?"
Steward Ke looked at her.
"Because killing him changes nothing."
Gu Yanshu added, "And because he is useful."
Ming Zhuo stared at him in disbelief.
"Useful?"
Gu Yanshu nodded.
"If the network believes he is still functioning normally, they will continue using him."
Steward Ke's eyes lit slightly.
"And that allows us to trace the orders."
"Yes."
T.A.R. rubbed his forehead.
"So instead of cutting the rope, we follow it."
"Exactly."
Ming Zhuo whispered, "You want me to continue working?"
Gu Yanshu looked at him.
"You already are."
The assistant steward trembled.
"What if they find out?"
Gu Yanshu answered calmly, "Then you die."
The bluntness shocked him into silence.
Steward Ke watched Gu Yanshu carefully.
"You do not soften truth."
"There is no benefit in doing so."
The girl looked slightly uneasy, but she said nothing.
Lin Qiren remained expressionless.
T.A.R. sighed quietly.
Steward Ke stepped closer to the table.
"So what do you suggest?"
Gu Yanshu tapped the report lightly.
"Three steps."
Steward Ke listened.
"First, Ming Zhuo continues receiving orders as usual. No change in behavior."
Ming Zhuo nodded weakly.
"Second, every instruction he receives is copied and recorded separately."
Steward Ke nodded.
"Third?"
Gu Yanshu's gaze moved toward the narrow window.
"We introduce a false route."
T.A.R. raised an eyebrow.
"A trap."
"Yes."
Lin Qiren asked, "What kind of trap?"
Gu Yanshu replied calmly.
"A shipment that does not exist."
The girl understood first.
"You want the network to react to it."
"Yes."
Steward Ke smiled faintly.
"And when they react, they expose themselves."
Gu Yanshu nodded.
"Exactly."
Ming Zhuo whispered, "What if they send someone powerful?"
Gu Yanshu looked at him.
"They will."
The assistant steward's fear returned instantly.
Steward Ke folded his arms.
"And who will handle that problem?"
Gu Yanshu's voice remained calm.
"We will observe first."
T.A.R. smirked slightly.
"And if observation fails?"
Lin Qiren answered instead.
"Then we fight."
The room settled into quiet agreement.
Steward Ke picked up the report and folded it again.
"Very well. We proceed with this plan."
Ming Zhuo looked like a man walking toward execution.
The girl placed a hand lightly on the table.
"When does it start?"
Gu Yanshu answered.
"Tonight."
Steward Ke nodded.
"I will prepare the false shipment record."
Lin Qiren turned toward the door.
T.A.R. pushed himself off the wall.
Ming Zhuo remained frozen.
As they prepared to leave, Steward Ke spoke again.
"One more thing."
They stopped.
"The network is not small. If they realize they are being watched, they will not hesitate to remove obstacles."
Gu Yanshu looked back at him.
"They already tried."
Steward Ke gave a quiet laugh.
"Then Area 900 will become much more dangerous."
Gu Yanshu stepped toward the exit.
"It already is."
Outside, the sky had darkened, and the lamps along the street flickered to life one by one. The town looked peaceful again, almost ordinary, as if nothing had changed.
But beneath that calm surface, routes were shifting, names were being written, and a false shipment was about to begin moving through invisible hands.
And somewhere in Area 900, someone would soon realize that the game they had been playing quietly was no longer under their control.Night settled over Area 900 in layers rather than all at once. The outer streets darkened first, then the market lamps dimmed, and finally the narrow administrative district around the Lower Records Hall became quiet enough that even distant footsteps sounded deliberate. The false shipment had already begun moving—not physically, but on paper, which was more dangerous. Names had been written. Routes had been assigned. Storage entries had been logged. In a town like this, paper moved before people did.
Gu Yanshu walked along the upper corridor of the inn, looking down at the street through the narrow wooden lattice. Lin Qiren sat at the table behind him sharpening his spearhead with slow, rhythmic strokes. T.A.R. leaned against the wall, arms folded, while the girl studied the copied route documents under the lamp.
No one spoke for a long time.
The silence was not uncomfortable. It was focused.
Finally, T.A.R. broke it.
"You're not telling us everything."
Gu Yanshu did not turn.
"There is nothing to tell."
"That's a lie."
Lin Qiren stopped sharpening but did not look up. The girl's fingers paused over the paper.
T.A.R. pushed himself off the wall and stepped closer.
"You don't create a false shipment just to see who reacts. That's too simple. You're waiting for something else."
Gu Yanshu watched a shadow move across the street below—someone carrying a lantern past the closed stalls.
"You're right."
T.A.R. narrowed his eyes. "Then say it."
Gu Yanshu turned slightly.
"The false shipment is not the trap."
The girl looked up.
"Then what is?"
Gu Yanshu walked back to the table and placed his hand on the copied route map.
"The trap is Ming Zhuo."
T.A.R. stared.
Lin Qiren's eyes sharpened.
The girl spoke softly, "Explain."
Gu Yanshu tapped the map lightly.
"The network believes Ming Zhuo is still under their control. They will continue sending instructions through him. But now Steward Ke is watching him. That creates tension in the structure."
T.A.R. frowned.
"So they'll try to remove him."
"Yes."
Lin Qiren nodded slowly. "To protect themselves."
Gu Yanshu continued.
"And when they try to remove him, they reveal their urgency. Urgency creates mistakes."
The girl understood.
"You want them to act quickly."
"Yes."
T.A.R. crossed his arms again.
"So the false shipment forces them to react, and Ming Zhuo forces them to panic."
Gu Yanshu nodded.
Lin Qiren asked quietly, "And what happens when they panic?"
Gu Yanshu looked at the lamp flame.
"They make contact with someone stronger."
The room grew quiet again.
Because that meant something dangerous was coming.
The girl folded the route paper carefully.
"Then we should protect Ming Zhuo."
Gu Yanshu shook his head.
"No."
T.A.R. blinked. "No?"
"If we protect him openly, the network will withdraw and disappear. They will abandon Area 900 and rebuild elsewhere. We gain nothing."
Lin Qiren leaned forward slightly.
"So we let him remain vulnerable."
"Yes."
The girl frowned.
"That's risky."
"Yes."
T.A.R. sighed.
"You say yes to everything dangerous."
"Because safe plans do not reveal hidden enemies."
That answer settled over the group heavily.
Outside, a faint bell rang somewhere in the distance, marking the late hour.
Gu Yanshu turned toward Lin Qiren.
"Have you noticed the patrol pattern?"
Lin Qiren nodded.
"Three guards every twenty minutes around the hall. Two around the market. None near the storage routes."
"Exactly."
T.A.R. looked annoyed.
"Why does that matter?"
Gu Yanshu answered calmly.
"Because someone redirected patrols away from the shipment routes."
The girl's eyes widened slightly.
"That means the network controls part of the guard rotation."
"Yes."
Lin Qiren said, "Or someone above the guards does."
Gu Yanshu nodded.
"Which means the problem is not limited to the records hall."
T.A.R. rubbed his temple.
"So Area 900 is already compromised."
"Yes."
The girl asked quietly, "Then what do we do?"
Gu Yanshu looked at the map again.
"We introduce a second variable."
T.A.R. groaned softly.
"Of course you do."
Lin Qiren almost smiled.
"What variable?"
Gu Yanshu pointed at a narrow route near the old grain lane.
"A traveler escort request."
The girl tilted her head.
"You want to escort someone?"
"No."
T.A.R. sighed.
"You want them to think we're escorting someone."
"Yes."
Lin Qiren nodded.
"That draws attention away from the shipment."
"Exactly."
The girl leaned forward.
"And while they watch the escort, the shipment moves."
"Yes."
T.A.R. smirked slightly.
"And when they attack the shipment, we see who moves."
Gu Yanshu nodded.
"And when they ignore the shipment and attack the escort, we see who they fear more."
Lin Qiren placed his spear aside.
"Either way, they reveal themselves."
"Yes."
The plan settled into place.
But the girl still looked uneasy.
"There is one problem."
Gu Yanshu looked at her.
"What?"
"We need someone believable to be escorted."
The room went quiet.
T.A.R. slowly turned his head toward Gu Yanshu.
"No."
Lin Qiren also looked at him.
The girl blinked.
"You mean—"
Gu Yanshu nodded.
"Ming Zhuo."
T.A.R. groaned.
"You're turning him into bait again."
"Yes."
Lin Qiren asked calmly, "Will he agree?"
Gu Yanshu answered without hesitation.
"He will."
The girl frowned.
"How do you know?"
Gu Yanshu spoke quietly.
"Because he is afraid."
T.A.R. shook his head.
"That's not enough."
Gu Yanshu looked toward the door.
"It is."
A soft knock came from the hallway.
Three taps.
Slow.
Uneven.
Lin Qiren stood immediately and opened the door.
Ming Zhuo stood there, pale and sweating.
"I… I need to speak with you."
Gu Yanshu gestured for him to enter.
Ming Zhuo stepped inside and closed the door quickly.
"There is a problem."
T.A.R. muttered, "That was fast."
Ming Zhuo's voice shook.
"I received another instruction."
Gu Yanshu remained calm.
"What instruction?"
Ming Zhuo handed over a small folded paper.
Gu Yanshu opened it.
One line.
Move storage key tonight.
Lin Qiren frowned.
"That's sudden."
The girl whispered, "They're already reacting."
T.A.R. looked at Gu Yanshu.
"You expected this."
Gu Yanshu folded the paper again.
"Yes."
Ming Zhuo looked desperate.
"What should I do?"
Gu Yanshu stepped closer.
"You will follow the instruction."
Ming Zhuo froze.
"But—"
"You will move the key."
"What if they kill me?"
Gu Yanshu looked directly into his eyes.
"They won't."
"How can you be sure?"
Gu Yanshu spoke calmly.
"Because they still need you."
Ming Zhuo's breathing slowed slightly.
"You… really think so?"
"Yes."
Lin Qiren watched quietly.
T.A.R. said nothing.
The girl studied Ming Zhuo's face carefully.
Gu Yanshu continued.
"You will move the key as instructed. Then tomorrow, Steward Ke will assign you an escort for safety."
Ming Zhuo blinked.
"An escort?"
"Yes."
His voice trembled.
"Why would he do that?"
Gu Yanshu answered simply.
"Because we will recommend it."
Ming Zhuo looked between them.
"You're trying to protect me."
Gu Yanshu did not correct him.
"Yes."
The word settled into Ming Zhuo like warmth.
His shoulders relaxed slightly.
"Thank you."
T.A.R. looked away, clearly irritated.
Lin Qiren remained silent.
The girl watched Gu Yanshu carefully.
Because she understood something Ming Zhuo did not.
This was not protection.
This was positioning.
Ming Zhuo left shortly after, clutching the paper like a lifeline.
When the door closed, T.A.R. exhaled sharply.
"You're using him."
"Yes."
Lin Qiren asked calmly, "Will he survive?"
Gu Yanshu looked at the lamp flame again.
"That depends on the network."
The girl spoke softly.
"And if they try to kill him?"
Gu Yanshu answered.
"Then we learn who they are."
The room fell silent again.
Outside, the wind moved through the narrow streets of Area 900, carrying faint dust and distant footsteps.
Somewhere in the darkness, someone was preparing to retrieve a storage key.
Somewhere else, someone was preparing to eliminate a witness.
And between those two intentions, Gu Yanshu quietly positioned every piece of the board, letting fear, trust, and necessity move people exactly where they needed to go.The paper in Ming Zhuo's hand had already gone slightly damp from his palm by the time he left the inn.
He walked as if every step could be seen, though the street was nearly empty and the lanterns above the shops had not yet fully brightened. Gu Yanshu stood in the shadow of the second-floor corridor and watched him move away with the careful pace of a man carrying a fragile lie. Lin Qiren had taken position near the rear street corner. T.A.R. had gone farther left, where the side alley opened toward the lower storage lane. The girl was already out of sight, likely circling above the rooftops or moving along the fence line where a watcher would not expect her.
The town held still in the way it only did before something important changed.
Gu Yanshu waited.
That was the hardest part for others. Waiting often looked like idleness, and people misunderstood idleness as weakness. But waiting, done correctly, was not passive. It was a form of pressure. It let the other side decide how much of themselves to reveal.
Ming Zhuo stopped at the end of the lane and looked around.
He had been told to move the storage key.
He had been told to follow the route exactly.
He had also been told, by implication and fear, that any deviation would make him useful only once.
So he moved on.
The key he carried was small, but he held it like a burden. The lower records hall would expect him to arrive at the eastern storage gate, where a clerk from the outer route would take it and file it in the usual log. If the network was watching, then the route itself was already compromised. If they were not watching, then the instruction was only meant to measure who would come.
Either way, the result would tell Gu Yanshu something.
Ming Zhuo turned into the narrow lane leading toward the old grain road.
The air there changed immediately. It was colder, carrying the smell of damp wood and stale sacks. The buildings leaned closer together, their walls patched and uneven, with the kinds of cracks that people stopped noticing until they had to run through them. There were fewer pedestrians here. Fewer witnesses. Which meant any movement felt louder.
He had not gone ten steps before he paused again.
Not because he heard something.
Because he sensed he was being followed.
Gu Yanshu saw the moment from above: a tiny hesitation, the stiffening of Ming Zhuo's shoulders, the way his left hand tightened around the key ring at his waist. He did not run. Good. Running now would make the shadow behind him move faster. Instead he kept going, and that was better. Fear that keeps moving can still be used.
A shape crossed the roofline opposite the lane.
Then another.
The watchers had arrived.
Gu Yanshu's expression did not change. He stepped away from the corridor railing and moved down the back stair. By the time he reached the street, Lin Qiren had also begun to shift, though casually, as if he were only taking a different route for no reason at all. T.A.R. emerged from the far end of the alley almost at the same moment, while the girl slipped down from a low wall behind a stack of crates, her eyes already fixed on the rooftops.
No one spoke.
The first attack came from the side wall.
A masked figure dropped from above and aimed not for Ming Zhuo's throat, but for his wrist.
Not a kill strike.
A capture strike.
Gu Yanshu noticed that instantly. They wanted the key. Or the person carrying it. Preferably both. The attacker's sleeve flashed with a dark thread line at the cuff, and in the brief motion of the landing Gu Yanshu saw the same blue stain that had marked the Lower Records Hall report tray.
The network had chosen a visible hand again.
Lin Qiren moved first, spear sweeping low enough to block the attacker from reaching Ming Zhuo. T.A.R. cut in from the opposite side, forcing a second figure back into the shadow between two walls. The girl's powder packet burst against a rooftop edge, throwing a pale cloud into the air and blurring the line of sight for anyone above.
Ming Zhuo froze for a breath.
Only a breath.
Then panic hit.
He stumbled backward and almost dropped the key.
Gu Yanshu stepped in at once, not touching him, only placing his voice where it would be heard.
"Keep moving," he said.
Ming Zhuo's face turned white.
"The key stays in your hand."
Another masked figure appeared ahead, blocking the lane.
Now they had the shape of it: a narrow funnel. Drive him forward, isolate him, pull him out of the escort line, and see who reached for him first. A test, yes, but also a method. The network was not merely trying to remove Ming Zhuo. It was trying to learn how the town's hidden defenders responded under strain.
Gu Yanshu did not waste time on anger.
He looked at the lane, the rooftops, the timing of the attackers, the angle of retreat, and found the weak seam at once.
He stepped close to Ming Zhuo and spoke softly, almost politely.
"Turn left when I touch your shoulder."
Ming Zhuo stared at him.
"That's all?"
"Yes."
He did not ask more. Gu Yanshu liked that. People who wanted the whole plan before it began were hard to guide. People who obeyed one step at a time were easier to carry through uncertainty.
Gu Yanshu touched Ming Zhuo's shoulder lightly.
The man turned left.
At the same moment, Lin Qiren struck hard enough to force the blocker ahead to retreat one pace. T.A.R. caught the opening behind them and forced the second attacker into the wall. The girl's powder, already drifting, settled into the line of sight of the rooftop watcher. That watcher hesitated.
And hesitation, for a hidden enemy, was often fatal.
Gu Yanshu guided Ming Zhuo through the narrow gap between two barrels and a drying frame, moving him into the one alley the attackers had not fully covered. It led behind a collapsed cart shed and into a sliver of space where the roof overhang blocked the sightline from above.
The attackers adjusted too late.
One of them called out a sharp signal.
Not a shout of panic. A signal.
That was worse. It meant coordination remained intact. It meant they were still thinking clearly. The network had not broken. It had only begun to understand the cost of the trap.
A man stepped into the center of the lane ahead of them.
He wore a plain brown robe, but his posture was too calm for a simple courier, too balanced for a guard. His face was narrow and clean-shaven, with a look that was not cold exactly, but emptied of ordinary feeling. The others immediately gave him space.
Lin Qiren's grip tightened on the spear.
T.A.R. looked at him once and muttered, "So that's the one."
The man smiled slightly.
"You've kept me busy," he said.
Ming Zhuo made a choking sound.
Gu Yanshu looked at the man carefully.
This one was different.
He did not carry visible arrogance. He did not rush. He did not need to make his strength obvious because the air around him already carried the weight of it. A person with this much control was more dangerous than the ones who shouted. The shouting ones could be baited. This one would decide whether to kill or retreat based on usefulness.
He looked at Ming Zhuo first.
Not at the escorts.
At Ming Zhuo.
And that confirmed the real role of the night.
The man spoke to Ming Zhuo in a quiet voice.
"You should not have continued working after the first warning."
Ming Zhuo trembled so hard he nearly dropped the key.
Gu Yanshu watched the reaction carefully. The enemy was not merely threatening him. He was trying to break the pattern of trust that had just started to form. If Ming Zhuo faltered here, he would become desperate. If he became desperate, he might flee. If he fled, the network would lose a useful channel and the hall would lose its bait.
Gu Yanshu stepped half a pace forward.
"Your words are too direct," he said.
The man's gaze moved to him.
Only then, as if noticing him for the first time, he gave Gu Yanshu a short look. "And you are too calm."
"That is because fear has already been spent."
A small pause.
The man smiled a little more.
"Interesting."
He did not attack yet. Instead he spoke to Ming Zhuo again, still quiet.
"You were always a tool. The hall only kept you because you were easy to move."
Ming Zhuo's breathing changed.
Gu Yanshu saw the exact moment the words landed. The man had chosen the right pressure point. Not violence. Not contempt. Identity. People could survive pain more easily than the realization that they had only ever been useful.
That was why Gu Yanshu allowed the words to continue.
A little more.
Just enough.
The man watched him, perhaps expecting interruption. When none came, his eyes sharpened.
"You do not stop me?"
Gu Yanshu answered evenly, "You are making a mistake if you think talking is helping you."
That drew the first true reaction.
A faint narrowing of the man's eyes.
Not anger. Recognition.
He understood now that the conversation itself was being watched, measured, and used. Which meant his advantage was shrinking.
He took one step forward.
Lin Qiren moved with him, spear angled across the lane.
T.A.R. and the girl shifted at the edges, forcing the masked attackers to hold back.
The man in the brown robe glanced once at the rooftops, then back at Gu Yanshu.
"Do you know what happens to people who rely on someone else's fear?"
Gu Yanshu's answer was quiet.
"They get predictable."
The enemy laughed under his breath, a small sound without warmth.
Ming Zhuo's eyes had gone glassy with panic.
Now was the point.
Not to save him from fear. To steer it.
Gu Yanshu spoke directly to him, voice low and steady.
"Ming Zhuo, look at me."
The man did.
"Breathe once."
He did.
"Hold the key."
Ming Zhuo tightened his hand.
"Good. Now listen. He wants you to believe your position was never real. That is how people like him break a person before the body gives out."
The enemy's expression changed at that.
Because Gu Yanshu had not only answered him. He had named the structure of the attack.
The psychological leverage fell apart by one edge.
Ming Zhuo's breathing steadied by a fraction.
Not enough to call it trust yet.
Enough to keep him from collapsing.
The enemy's gaze drifted briefly to the key in Ming Zhuo's hand, then back to Gu Yanshu. "You know how to talk to broken people."
Gu Yanshu did not deny it.
"I know how to keep them from becoming useless."
That sentence landed harder than any threat could have.
The man in brown robe stared at him for a long moment, then let his shoulders ease slightly. That relaxation was not surrender. It was selection. He had decided this would not be the place to fully commit.
Which meant he was leaving with information.
That was not ideal.
But it was still a kind of success.
The man took one more step back and raised two fingers. The masked attackers immediately pulled away from the lane roofline and the wall edges, dropping into retreat positions with disciplined coordination.
Lin Qiren's expression darkened. "He's retreating."
"Not yet," Gu Yanshu said.
The enemy gave one final glance toward Ming Zhuo.
"You will be watched more closely now," he said.
Then, to Gu Yanshu: "And so will you."
He vanished into the lane shadows with the others following his movement like obedient pieces.
No chase.
No final strike.
Just withdrawal.
That was the worst kind of enemy. The kind that did not fail loudly.
T.A.R. looked after them, annoyed. "They left too cleanly."
The girl checked the rooftops. "They wanted to be seen retreating."
Lin Qiren nodded once. "To tell someone higher up what they found."
Ming Zhuo was still standing in the center of the lane, pale and shaken, but no longer frozen. He looked at Gu Yanshu as if trying to understand whether he had just been rescued or reshaped.
Gu Yanshu took the key from his hand only after the man was steady enough to release it.
Then he said, "Go back to the hall."
Ming Zhuo blinked. "What?"
"Tell them the escort was effective."
"That's it?"
"Yes."
Ming Zhuo's mouth opened, then closed.
"What if they ask why the attackers retreated?"
Gu Yanshu looked in the direction the enemy had vanished.
"Tell them the escorts were stronger than expected."
That answer was enough.
Ming Zhuo nodded quickly and stumbled away, obeying before fear could argue.
When he was gone, the lane fell back into a narrow and uneasy quiet.
T.A.R. folded his arms. "So now what?"
Gu Yanshu looked toward the dark end of the street where the enemy had disappeared.
"Now they know we can protect what they want to steal."
Lin Qiren's eyes narrowed slightly. "And that changes things."
"Yes."
The girl asked quietly, "How?"
Gu Yanshu slipped the storage key into his sleeve and turned toward the inn.
"They will stop thinking about stealing the bait," he said. "And start thinking about who placed it."
T.A.R. went still.
Lin Qiren looked at him.
The girl's expression changed by a fraction.
Because that was the real bait now.
Not Ming Zhuo.
Not the false shipment.
Not even the route paper.
The bait was the possibility that there was a mind behind the setup sharper than the enemy expected, one that could build a trap, then remain invisible inside it long enough for the other side to wonder whether they had already been watched from the beginning.
And in the cold streets of Area 900, with the first enemy retreating and the next one already beginning to think, Gu Yanshu let that doubt settle exactly where he wanted it.
