The thing behind Shen Lu didn't move like a beast.
It moved like a rule.
A pale hand formed out of the red mist and carved grooves, jointed wrong, fingers too long, as if the corridor itself had decided to reach up and claim what it was owed.
Shen Lu's spine went rigid.
He was still half-hanging over the pit, Helian Feng's grip crushing his wrist, the suppression field making everything heavier, slower, uglier.
The hand reached.
Not for Helian Feng.
For Shen Lu's throat.
Shen Lu reacted without thinking.
He snapped his other hand up and flicked his fingers.
A thin line of toxin mist silk snapped into existence, invisible in the bloodlight until it moved. The Cloud Venom Silk Whip didn't fully manifest in this suppression field the way it usually did. It felt muted, like a blade wrapped in cloth.
Still—its origin was not ordinary.
It was bound to his soul.
It answered him even when the realm tried to silence everything else.
The whip lashed across the pale hand.
A hiss like hot metal plunged into water.
The hand recoiled, fingers curling, but it didn't dissolve. It simply… learned. The grooves that made it shifted, re-forming.
Shen Lu's breath came out sharp. "It's not alive."
Helian Feng didn't answer. His eyes were on the hand, his posture steady despite the strain of holding Shen Lu up.
"Then it's easier," Helian Feng said, voice cold.
Lightning cracked.
Not a full technique.
Just a thread.
Even suppressed, Helian Feng's thunder root didn't disappear. It compressed. It became thinner, harsher, more precise.
A narrow line of pale-blue lightning ran down Helian Feng's arm, into his hand, and into the point where his fingers gripped Shen Lu's wrist.
Shen Lu's nerves lit up.
Pain, sharp and clean, shot through his arm like it had been branded.
He nearly cried out.
But then he realized Helian Feng wasn't shocking him.
Helian Feng was using the lightning as a tether.
A hook.
A thread of force that could hold Shen Lu without letting go.
Helian Feng's other hand drew his sword in a single motion.
The blade flashed.
A clean, surgical arc.
It didn't cut the hand.
It cut the groove-lines that fed the hand.
Stone screamed.
The bloodlight flickered.
The pale hand convulsed, fingers twisting like dying worms.
Shen Lu's whip snapped again, wrapping around the wrist of the hand and yanking hard, dragging it toward the pit.
The pit's red mist surged eagerly.
The hand resisted, claws scraping the stone, trying to anchor itself back into the corridor's rules.
Helian Feng's sword struck a second time.
The groove-lines split deeper.
The corridor trembled.
A low groan rolled through the stone like the realm itself didn't appreciate being damaged.
The hand finally tore free.
It fell into the pit like a piece of broken law.
The red mist swallowed it with a sound like a sigh.
For a heartbeat, everything went still.
Then Helian Feng hauled Shen Lu up with the lightning tether and brute force combined.
Shen Lu slammed onto the far side of the corridor, palms scraping stone, chest heaving.
The suppression field pressed down on him like a weight. His arm burned where Helian Feng's lightning had threaded through his nerves, not injuring, but forcing his body to obey the tether.
Helian Feng released him immediately.
Too immediately.
As if touch itself was something Helian Feng had to ration.
The outer disciple stumbled over, face chalk-white. "We— we almost—"
"Shut up," the severe talisman disciple hissed. His own hands were shaking, not from fear alone but from how much qi the toll had shaved off.
The pit behind them shuddered.
The bloodlight dimmed, reluctant.
The toll had been paid.
Helian Feng's gaze swept the corridor. "Move. Before it decides it wants more."
They ran again.
The corridor narrowed, then widened into a chamber with a cracked ceiling that dripped condensation like sweat. The air here was colder, and the suppression pressure eased slightly, as if the realm had grown bored of watching them struggle.
Shen Lu's breath steadied.
His wrist throbbed where Helian Feng had gripped him.
A purple bruise was already blooming.
Helian Feng's gaze flicked to it once, unreadable, then away.
"Don't slow," Helian Feng said.
Shen Lu's lips twitched faintly. "I'll try not to fall into any more holes."
Helian Feng didn't laugh.
But something in his eyes tightened, like the ghost of a reaction he refused to allow.
They crossed the chamber and found another corridor ahead. This one had no grooves, no script lines. Just smooth stone and faint mist crawling along the floor.
Too clean.
Too quiet.
The fox-spirit refused to step forward.
It dug its paws into the stone and trembled.
The beast tamer's voice was strained. "It won't go."
Helian Feng's eyes narrowed. He lifted his hand and flicked a small stone forward.
The stone skittered across the smooth floor.
Halfway down the corridor, it vanished.
Not fell.
Vanished.
Like it had been erased from the world.
The mist on the floor rippled, as if swallowing.
The severe talisman disciple swallowed hard. "A stripping field."
Shen Lu stared at the corridor, throat tight. He'd seen something like this in the book. A corridor that ate items, then ate qi, then ate people—starting with what was easiest.
A filter.
A culling tool.
Helian Feng's voice was flat. "We don't have a choice."
Shen Lu's fingers curled inside his sleeves.
He could bypass this.
He had the pendant space.
He could step in, reposition, maybe even slip around the stripping field's boundary and re-enter ahead.
But Helian Feng would see.
Helian Feng would know.
And Helian Feng had already drawn a line, even if he wasn't saying it aloud.
Protect me, don't cross the line. I find the cure myself.
Don't use the secret where I can't control it.
Shen Lu swallowed.
He stepped forward with the others.
The moment his foot touched the corridor's smooth floor, his sleeve felt lighter.
His hidden vial—the one holding the black pellet key—tugged, as if the corridor had noticed it.
Shen Lu's stomach dropped.
The stripping field wasn't eating random items.
It was reaching for what mattered most.
What was unusual.
What didn't belong.
He forced himself to keep walking.
Two steps in, the talisman disciple's charms began to crumble into gray dust inside his sleeve. He gasped.
Three steps, the outer disciple's spare sword clattered to the ground, its spiritual glow snuffed out like a candle.
Four steps—
Shen Lu felt the pendant at his chest grow suddenly hot.
Not heat.
Attention.
The corridor's mist surged higher, brushing his robes like fingers searching for a seam.
Yuan's voice murmured, amused and lazy. "It can smell your hiding place."
Shen Lu's blood ran cold.
He kept his face blank.
He kept walking.
Because turning back would only make the corridor hungrier.
And somewhere behind them, far back through the halls, a faint sound echoed—distant, muffled, but unmistakable.
Footsteps.
Multiple.
Fast.
Rivals had found another way.
And the corridor they were trapped in was starting to reach for Shen Lu's heart.
