Mira closed the archive door with her foot.
The sound was small.
It still felt like slamming a coffin.
Jaehyuk didn't look back.
He couldn't.
Not after the word on the page.
Regressor.
Not as an insult.
Not as a rumor.
As a category.
As if someone had filed it in a drawer and decided it belonged there.
Somin kept walking until the lights changed and the Tower corridor returned, rough stone replacing clean walls.
Then she stopped.
"So," she said. "What did we just steal?"
"A page," Jaehyuk said.
"No. Don't do that." Her voice sharpened. "What did we steal?"
Mira leaned against the wall. Her breathing had slowed. Her eyes hadn't.
"Something that's not meant for climbers," she said.
Somin rubbed her palms like she could scrub the archive smell off. Old ink. Wet metal. That antiseptic sweetness that made her stomach twist.
"I hate that place," she muttered.
"Good," Mira said.
"Stop agreeing with me like it's your job."
Mira's mouth moved. Not quite a smile. "It's practice."
Jaehyuk unfolded the page again.
The paper was thick. Real. The edges were worn like it had been handled by a lot of hands.
There were stamps on it.
Not Tower notices.
Not system prompts.
Administrative stamps.
One was a simple circle with a number.
7.
Another was a word in Korean that made his throat tighten.
반복.
Iteration.
Somin leaned over his shoulder. "Is that... is that your number?"
"Yeah," Jaehyuk said.
Mira's voice was flat. "It was already on the wall in the boss chamber."
Somin flinched. "Don't remind me."
Jaehyuk scanned the paragraph he could actually read.
Most of it was written in formal language that felt like it had been translated by a machine.
But one line was clear.
REGRESSOR DESIGNATION: ACTIVE.
Below it, smaller text.
COUNT STATUS: SEVEN.
Somin stared. "Count? Like... they're counting you?"
"Yes," Mira said.
"Who is they?"
Jaehyuk's thumb tapped the paper.
Once.
Twice.
Controlled.
"The Tower," he said.
Somin's voice dropped. "The Tower is alive."
"No," Jaehyuk said.
He wanted that to be true.
He wanted it to be a machine.
Machines were predictable.
"It's not alive," he said. "It's learning."
Mira watched him. "Difference?"
"A machine that learns doesn't care if you scream." His eyes stayed on the page. "It only cares if you repeat."
Footsteps approached from the corridor ahead.
Jaehyuk folded the paper and slid it into his inner pocket.
The Broker walked into view like he'd been there the whole time and was only now deciding to become visible.
His coat was neat.
His hands were clean.
His eyes were tired.
That's what scared Jaehyuk the most.
The Broker never looked tired.
"You got it," the Broker said.
"You knew it was there," Jaehyuk said.
"I suspected." The Broker's gaze flicked to Somin. Then to Mira. "You went in anyway."
Somin lifted her chin. "We don't take orders from you."
"No," the Broker said. "You take prices."
Jaehyuk stepped closer.
The air around the Broker smelled like tea and coins.
Metal. Ink. Something sharp, like the scent of an antiseptic wipe.
Jaehyuk hated how everything kept pointing back to the archive.
"Tell me about Floor 150," Jaehyuk said.
The Broker blinked once. Slow.
"That's what you want?" he asked.
"Iteration 6 said Vanguard is the only group trying to reach above 150." Jaehyuk's voice stayed low. "Why is 150 a line?"
The Broker tilted his head. "Because above 150, the Tower stops pretending."
Mira's grip tightened on her sword strap. "Explain."
"The Seven Kings," the Broker said. "They climbed deep. None of them returned unchanged. You think that's a metaphor. It's not."
Somin swallowed. "You mean... mind control?"
"I mean the Tower edits people," the Broker said. "Not with death. With survival."
Jaehyuk felt his jaw tighten.
"No iteration has reached Floor 200," the Broker continued. "Not in any recorded cycle."
Somin's eyes widened.
Mira made a sound of disbelief that she tried to swallow.
"Recorded?" Somin asked.
The Broker's gaze flicked to Jaehyuk's pocket. "Counted."
Jaehyuk held still.
"Seven is a threshold," the Broker said, voice almost gentle. "That's what your page means."
"I already heard that," Jaehyuk said.
"No," the Broker said. "You heard it as a threat. I'm telling you it's a measurement."
Somin stepped forward. "Who is measuring?"
The Broker looked at her.
For a moment his transaction face slipped.
Not empathy.
Respect.
"The Tower doesn't need to guess anymore," he said. "It has six attempts worth of data. It has watched people like him try the same clever moves. The same rescues. The same shortcuts."
Jaehyuk's stomach turned.
Floor 23.
The swap.
The add cell.
Had someone else done a version of it?
Had the Tower seen it before?
"Is that why things keep changing?" Somin asked.
"Yes," the Broker said. "You are not fighting a static dungeon. You're fighting an adaptive system."
Mira's eyes narrowed. "And Vanguard?"
The Broker shrugged. "Vanguard wants access. Above 150 is where access becomes authority."
"Authority over what?" Somin asked.
The Broker didn't answer.
That meant the answer was expensive.
Jaehyuk took another step closer.
His voice dropped.
"Tell me why there were six before me."
The Broker stared at him for a long time.
Then he smiled. Not amused. Not kind.
Tired.
"Because after seven," the Broker said, "the Tower doesn't need regressors anymore."
Somin's face tightened. "What does that mean?"
"It means it will have learned enough," the Broker said. "Enough to stop all of them."
Jaehyuk's hands curled.
Not into fists.
Into control.
"And me?" Jaehyuk asked.
The Broker looked at him like he was reading an invoice.
"You're the last one," he said.
The words hit harder than any punch.
Mira's breath caught.
Somin's hand found Jaehyuk's wrist.
Not a grab.
Not a plea.
A touch.
Warm.
Real.
Like a reminder that he was not a file.
Not a number.
Not a count.
Just a person trying to keep people alive.
She held his wrist for a second.
Then let go.
Jaehyuk didn't look at her.
If he did, he'd break.
"Make it count," the Broker said.
He turned away.
Then stopped.
"One more thing," he added.
Jaehyuk waited.
"Floor 40," the Broker said. "The Tower will announce something that forces guilds into open conflict."
Mira's gaze sharpened. "A war floor?"
"A tournament," the Broker said. "Mass guild conflict. The kind that lets the Tower gather data faster."
Somin's voice went small. "How do you know?"
The Broker didn't look back.
"Because it's happened every time," he said.
He walked into the corridor and disappeared.
Jaehyuk stood still.
The word regressor burned in his pocket.
Seven burned behind his eyes.
And somewhere above them, far above, the Tower was already preparing a stage.
Not to test climbers.
To count them.
To break them.
To learn.
A soft chime echoed through the hall.
Not from the Broker.
From the system.
From the Tower.
[Notice]
[Floor 40 — Mass Guild Conflict Tournament Pending]
[Registration opens soon]
Somin stared at the floating text.
"Pending," she muttered. "Like it's... excited."
Mira looked at Jaehyuk. "That's fast."
Jaehyuk's mouth tasted like coins.
He didn't like how the Tower moved when he learned something.
Like it didn't want him to hold information without paying.
"Yeah," he said. "It is."
They started walking again.
Floor 31 wasn't built like a dungeon.
It was built like a hallway between decisions.
The stone under their feet shifted from rough to smooth to rough again, as if the Tower couldn't decide what skin to wear.
Somin kept glancing at Jaehyuk's pocket.
"Does the page say anything else?" she asked.
"Enough," Jaehyuk said.
"That's not an answer."
"It's the only one I'm giving right now."
Mira snorted softly. "He's back to being unbearable."
"He was unbearable before," Somin said. "Now he's unbearable with lore."
Jaehyuk ignored them.
He was listening.
Not for monsters.
For patterns.
Floor 31 had a sound under the sound. A low hum that matched the archive lighting. A frequency that lived under his tongue.
Count.
Measure.
Learn.
The corridor opened into a wide chamber with a gate at the far end.
The gate wasn't stone.
It was metal.
Polished steel set into the wall like a vault.
And on it was a symbol.
Not Korean.
Not a number.
A crown.
Seven small spikes.
"That's new," Mira said.
Somin's voice tightened. "Is that..."
"Seven Kings," Jaehyuk said.
The gate recognized his voice.
Not with text.
With motion.
The vault door unlocked with a slow click that made Mira's hand tighten on her sword.
"I don't like that," she said.
"Me neither," Jaehyuk said.
Somin stepped closer to the gate, careful. "Above 150..." Her voice was small. "Do you think the Kings went through doors like this?"
Jaehyuk stared at the crown symbol.
He thought of Mira.
Future Mira.
A king.
A person who climbed deep and came back with something sharp behind her eyes.
"Yeah," he said. "I think they did."
The gate opened.
The air on the other side was hot and dry, like breathing over concrete in summer.
A floor transition.
Not to another dungeon.
To a place that smelled like ash and metal.
Somin coughed once. "This is..."
"War air," Mira said.
Jaehyuk stepped through.
And felt the Tower adjust around him like a camera focusing.
The last thing the Broker had said replayed in his head.
Make it count.
Jaehyuk looked back once.
The crown symbol on the vault gate had shifted.
The seven spikes were darker now.
Like someone had pressed a thumb into wet paint.
Like the Tower had marked him the way it marked everything else.
Seven.
Counted.
And still walking.
