The underworld did not announce itself with screams.
It greeted you with manners.
Shen Lu followed Helian Feng down the last set of stone steps and felt the air change. Above ground, the night market had smelled like fried dough and incense and cheap wine. Down here it smelled like cold stone, old smoke, and something faintly metallic that clung to the back of the throat.
He kept his mask on. He kept his breathing even.
He told himself this was simple.
Sell pills.
Get low-grade spirit stones.
Feed the space.
Live.
But his pendant rested warm against his skin, and the warmth was not comfort. It was a reminder that he carried a secret that could ruin him if the wrong person looked too closely.
Helian Feng walked beside him, not ahead, not behind. Close enough that their sleeves nearly brushed.
That was its own kind of danger.
A guard lounged at the bottom of the stairs, one boot propped against the stone wall like he owned the darkness. His face was half-covered, but his eyes were sharp and bright.
He held out a hand without speaking.
Shen Lu placed the cracked-coin token into his palm.
The guard rolled it between two fingers, then looked up at Helian Feng.
The pause stretched.
Not suspicion. Not exactly.
Calculation.
Shen Lu forced his voice to sound bored. "Bodyguard."
Helian Feng didn't speak. He didn't even tilt his head. He stood there like a black wall and let the guard measure himself against it.
The guard's throat bobbed once.
Then he leaned back and waved them through, suddenly uninterested.
Shen Lu kept walking, but his pulse stayed high.
Helian Feng's presence made doors open.
Helian Feng's presence also made people remember their knives.
They entered the auction hall.
It wasn't large, but it was deep. The ceiling disappeared into darkness. Gauze curtains hung in layers, softening edges, turning faces into shadows. Pale lamps burned along the walls, their flames steady in a way that felt unnatural, as if even fire understood rules down here.
People sat scattered across the stone tiers. Masks of cloth, wood, lacquer. Some ornate, some plain, all meant to hide too much.
Shen Lu's gaze skimmed the crowd without seeming to.
A merchant ring, heavy with spirit patterns.
A righteous sect sleeve hidden under a black cloak.
A woman with clean boots and cleaner eyes, sitting here like she'd paid for the privilege of watching other people bleed.
Shen Lu sat where the handler directed him.
Helian Feng did not sit.
He stood behind Shen Lu's right shoulder, silent and steady.
Shen Lu felt that steadiness like weight. Protection, yes.
Also a reminder that Helian Feng would notice everything.
He murmured, barely moving his lips, "Try not to look like you're deciding who deserves to keep breathing."
Helian Feng's voice came low. "I am."
Shen Lu's mouth twitched under his mask. "Great. Comforting."
In the jade space, Little Root's presence pressed faintly against Shen Lu's mind, impatient as always.
Master. Aura.
Shen Lu answered silently, I know.
Yuan's voice slipped in, arrogant and unimpressed. Master, these humans smell like greed.
Shen Lu almost sighed. Like you don't.
The auction began.
The first lots were bait. Warm-up items that made people feel brave.
A bundle of talismans sealed in wax. Half were real, half were lies. Everyone bid like they didn't care which.
A spiritual beast egg with a cracked shell. The auctioneer promised it would hatch into something rare. The bidders promised they believed him. The price climbed anyway.
A rusty sword fragment displayed on velvet. The auctioneer's voice slid smooth as oil.
"An immortal remnant," he said. "A trace of intent. For those who wish to borrow destiny."
Shen Lu watched bidders lift their hands and felt his stomach twist.
Borrow destiny.
That was the problem.
Everyone here wanted what wasn't theirs.
He forced his focus back to his own goal.
Spirit stones.
Low-grade only. He wasn't stupid enough to dream of anything else.
His fingers curled inside his sleeves. He checked the hidden compartment at his belt with a subtle shift.
Still there.
Three bottles.
The handler came for him halfway through the second round, gliding to his seat like a shadow that had learned manners.
"Masked Alchemist," the handler whispered. "Your appraisal is ready."
Shen Lu stood.
Helian Feng moved with him instantly, like he'd been waiting.
The handler's gaze flicked to Helian Feng. "Only the seller—"
"He stays," Shen Lu said.
The handler hesitated just long enough for Shen Lu's heartbeat to thud once, hard.
Then the handler dipped his head. "As you wish."
As if Shen Lu had wishes down here.
They were led through a narrow corridor where the stone sweated cold moisture. The walls carried old carvings that looked like blessings until you stared long enough to see they were restraints.
The appraisal room was small and bright. Too bright. Light from a formation plate embedded in the table made everyone's masks look cheap.
Three appraisers waited. Faces half-covered, eyes sharp and bored.
They didn't greet Shen Lu.
They didn't greet Helian Feng.
Their attention was already on Shen Lu's hands.
Shen Lu set the first bottle down.
One appraiser broke the seal with a finger, careful. The formation plate flared. A thin wisp of light rose and formed an illusion of the pill inside, round and flawless.
The lead appraiser's boredom cracked.
"Stabilization," the man said. "For meridian backlash."
Shen Lu didn't nod. He didn't confirm. He simply said, "It works."
The man's gaze sharpened. "Your age?"
Shen Lu's pulse jumped. That wasn't curiosity. That was inventory.
Shen Lu's voice cooled. "Old enough to sell."
Behind him, Helian Feng shifted.
Not a step.
A warning.
The appraisers pretended not to notice. But their throats tightened. Their eyes slid away and back too fast.
The lead appraiser cleared his throat like he'd bitten something sharp. "Second bottle."
Shen Lu set it down.
The illusion rose darker this time, a faint purple sheen lacing the surface like ink swirled into water.
"Purge," the appraiser murmured, interest creeping in. "A harsh one."
"It doesn't have to be harsh," Shen Lu replied. "Poison just doesn't leave politely."
One appraiser let out a quiet laugh, surprised, as if humor had no business in this room.
Helian Feng didn't.
Shen Lu set the third bottle down and felt his pendant warm faintly, like it recognized the gamble.
Little Root's presence tightened.
Master. Careful.
Shen Lu kept his hands steady.
The formation plate flared.
The illusion rose—
And the room changed.
The pill's sheen was too clean. Too bright. Too complete. The spiritual pattern held together as if it had been pressed into place by something patient and merciless.
The lead appraiser leaned forward. "This flame," he said quietly. "Not ordinary."
Shen Lu's blood cooled.
He hadn't used the Heavenly Star Lotus Flame yet, not openly, not even here. But the space-fed herbs and his own desperate precision were leaving traces—too neat, too efficient for a junior alchemist with no backing.
Shen Lu met the man's stare through his mask. "You're paying for a pill, not a confession."
The appraiser's eyes glittered. "Some confessions are more valuable."
Helian Feng spoke, voice like a blade laid flat on stone. "List it. No questions."
The appraisal room chilled.
The lead appraiser's gaze flicked to Helian Feng and away again, like his eyes had touched lightning.
"Of course," the appraiser said quickly. "It will be listed. Discreetly."
Shen Lu left the bottles behind.
Back in the corridor, he exhaled a breath he hadn't realized he'd been holding.
Helian Feng walked at his side now, not behind. Close enough that their sleeves brushed once, silk against silk.
Shen Lu's skin tightened anyway, as if it could feel the contact longer than it lasted.
"You shouldn't have done this alone," Helian Feng said.
Shen Lu gave a dry laugh. "I didn't."
Helian Feng's eyes narrowed. "I meant… without telling me."
There it was.
The real danger wasn't the underworld. It was Helian Feng's questions.
Helian Feng's control disguised as concern.
Shen Lu kept walking. "You would've stopped me."
"I would've asked why," Helian Feng corrected.
Shen Lu almost snapped the truth at him.
Because I'm trying to live.
Because the book killed me for fun.
Because I don't have anyone to lean on and I refuse to start now.
Instead he used the only armor that had ever fit him well.
A joke.
"Because I enjoy the atmosphere," Shen Lu said lightly. "Black lamps, criminals, you glaring. Very romantic."
Helian Feng didn't smile. But his voice softened by half a shade, barely noticeable unless you were Shen Lu and you listened too hard.
"Shen Lu."
Shen Lu's chest tightened.
"Yes?"
Helian Feng paused, then asked in a voice too precise to be casual, "What did the exit formation taste?"
Shen Lu stopped walking.
The question was a hook.
A test.
He felt Little Root's warning like leaves snapping in a storm.
Yuan's mind-voice coiled low. Master.
Shen Lu kept his hand away from his pendant. Kept his fingers curled in his sleeve so they couldn't betray him.
He forced his voice into careless sarcasm. "Blood. Obviously."
Helian Feng's gaze didn't move. "Only blood?"
Shen Lu's throat went dry behind the mask.
He couldn't answer.
So he lifted his chin and smiled in his voice, because if he didn't, something inside him would crack.
"If you want to interrogate me," Shen Lu murmured, "pick a better place. This corridor has terrible acoustics."
Helian Feng stared at him for a long beat.
Then, unexpectedly, he stepped back half a pace.
Not retreating.
Giving space.
"Fine," Helian Feng said. "Later."
Later meant private.
Later meant Helian Feng could look at him without witnesses.
Later meant Shen Lu might slip.
They returned to the hall.
The bidding began again like a heartbeat.
Shen Lu sat, hands hidden, pulse climbing. Helian Feng resumed his place behind him, silent as a shadow.
The auctioneer's voice rose and fell.
When Shen Lu's first bottle appeared, the bids climbed fast. Low-grade spirit stones clinked and poured into counting trays. The sound was almost comforting. Almost normal, if you ignored the masks and the way people watched one another like wolves.
His second bottle went higher.
Poison was common.
A cure that actually worked was rare.
Shen Lu swallowed, watching the stacks grow. He could already imagine feeding the space. Pouring spirit stones into the soil until aura thickened and herbs stopped looking starved. He could almost feel the relief in Little Root's presence.
Then the third bottle came.
The hall tightened.
Even through masks, Shen Lu felt attention sharpen into hunger.
The auctioneer's voice turned silky. "Limited. One bottle. One chance."
Bids rose like fire.
Low-grade stones first, thrown down in sacks, counted in rough piles. The numbers climbed until Shen Lu's mind began to float away from them, as if this couldn't possibly be real.
A bidder called out a price. Another raised it.
Someone scoffed.
Someone laughed too softly.
Then, when the next bid came, it wasn't a sack.
It wasn't a pile.
A single spirit stone slid onto the auction platform.
Not large.
Not bright.
Just… clean.
Mid-grade.
The hall went silent so fast it felt like the air had been cut.
That one stone didn't clatter.
It landed with a soft, sure sound, the way a verdict sounded in a quiet room.
Shen Lu felt his stomach drop.
Mid-grade stones didn't move in the lower world unless a large sect or a great family allowed it.
And this wasn't just a mid-grade stone.
It carried an imprint.
Not flashy.
Not ornate.
A crisp, clinical crest like a contract stamp pressed into the surface: a stylized cauldron over a straight line, neat enough to make Shen Lu think of ledgers and debts.
Helian Feng went still behind him.
Not tense.
Not surprised.
Just… precise, like a man recognizing an enemy's blade.
Shen Lu didn't turn his head, but his voice came out smaller than he wanted. "You know that mark."
Helian Feng's answer was quiet. "Yaochuan."
The name landed heavier than the stone.
Great Alchemy House.
The kind that didn't need sect approval because sects needed them. The kind that could starve a city of pills by raising prices with a polite smile. The kind that made enemies by existing and made friends by selling antidotes at the right moment.
Shen Lu's mouth went dry.
Because they hadn't bid emotionally.
They hadn't even hesitated.
They had simply decided the price.
The auctioneer's voice returned, careful now, as if even he didn't want to offend the person behind that single stone. "Mid-grade bid recognized."
No one countered.
Not because they couldn't add more low-grade stones.
Because everyone understood what it meant to challenge Yaochuan in public.
"Sold," the auctioneer declared, voice too smooth.
The mallet fell.
The sound echoed like a door closing.
Shen Lu's hands trembled once inside his sleeves.
He pressed his fingers together hard enough to hurt. Pain anchored him.
He should have been relieved. He'd gotten more than he expected.
Instead he felt watched.
Claimed.
Marked by a gaze he couldn't see.
Helian Feng leaned closer, voice low enough to be for Shen Lu only. "From now on, you do nothing alone."
Shen Lu's heartbeat stuttered. "That sounds like an order."
"It is," Helian Feng said.
Shen Lu swallowed. His pride rose sharp and automatic.
Then he remembered the mid-grade stone.
He remembered the crest.
He remembered that he had just sold a miracle to a house that treated miracles like inventory.
Shen Lu's voice came out rougher. "They'll want to know who I am."
Helian Feng didn't deny it.
He only said, colder, "Let them try."
Shen Lu wanted to believe him.
He wanted to lean back into that certainty and let it hold him up.
He didn't.
He couldn't afford to.
So he forced air into his lungs and forced his voice into something almost steady.
"Fine," Shen Lu murmured. "But if we die, I'm haunting you."
Helian Feng's pause was small.
Then, unexpectedly, his voice softened just a fraction. "You won't."
Shen Lu stared at the pale flames burning steady along the wall and felt the pendant at his throat pulse once.
Warm.
Satisfied.
Almost… awake.
In the jade space, Little Root's leaves began to shake—not warning this time, but anticipation, as if the plant could feel the coming flood of aura.
And Shen Lu, sitting under black lamps with a new kind of attention on him, realized the auction had done what the secret realm couldn't.
It had let him escape death.
And it had traded that escape for a name he wasn't ready to carry.
Yaochuan.
