The elite lay where it had fallen. One limb twitched once, then stilled again.
Michael didn't look back.
The next passage sloped downward, the air cooling and tightening as the walls pressed closer. The broken stone of the previous chamber gave way to something cleaner here. Less fractured. Less worn.
Too clean.
Min-ho led, though not as far ahead as before. He slowed near corners now, glancing back without quite admitting he was doing it.
Yuri's steps grew quieter. Her staff hovered just above the ground instead of tapping it.
Dae-sung stayed to the right, conserving movement, watching angles instead of reacting to them.
Park drifted toward the rear left, never far, never in the way.
No one commented on the shift.
They didn't need to.
Michael's marker pulsed faintly ahead.
Closer. Still descending.
He scanned as he walked.
Floor seams. Wall cuts. The curve of the ceiling where stone met something shaped instead of formed.
This wasn't a cave anymore.
It was built.
Min-ho slowed at the first turn. "You feel that too?"
"Yes."
Min-ho glanced back. "That's not an answer."
Michael lifted the SMG slightly, pointing ahead. "Look at the floor."
They stopped.
At first glance, nothing stood out. Same stone. Same damp sheen. Same thin layer of dust.
Then Yuri crouched.
"…There."
A seam. Clean edges. Too straight to be natural.
Dae-sung leaned in, then pulled back before crossing it. "Pressure plate."
Michael's gaze lifted.
Small holes lined the ceiling above the section.
Min-ho exhaled slowly. "Good catch."
Michael shrugged. "It didn't match the rest."
Yuri tapped the edge with her staff. "Darts, maybe."
"Or something heavier," Dae-sung said.
Min-ho glanced down the corridor. "No way around it?"
Michael checked the walls.
Too tight. No break in structure.
Then he looked higher.
Stone ribs jutted from the left wall, uneven but close enough to use.
"There."
Park saw it at the same time. "We go over."
Min-ho frowned. "We?"
Park had already stepped forward.
He moved without forcing it, foot to wall, then to the first ridge, crossing the corridor without touching the plate. He landed lightly and turned back.
"Stable."
Dae-sung followed. Less clean, but controlled.
Yuri hesitated, then sighed. "If I fall, I'm blaming all of you."
"You won't," Michael said. "Keep your weight close."
She gave him a look, then went anyway.
Min-ho stared at the wall, then at the plate. "This is a bad idea."
"It's the only one," Yuri said from the other side.
He grunted and started climbing.
The second ridge slipped under his boot. He caught himself with a hard scrape of metal on stone, breath hitching, then forced the rest of the crossing.
When he landed, he didn't say anything.
Michael went last.
A step. A shift. Hands brushing the wall just enough to keep balance.
Across.
The system flickered.
Movement optimization active.
He ignored it.
On the far side, Dae-sung brushed dust from the wall. "It's not trying to slow us down."
"It's trying to make us rush," Yuri said.
Michael nodded once.
They moved on.
The tunnel split around a thick pillar of black rock.
Left sloped down into damp shadow. Right-angled upward, cleaner, quieter.
Michael's marker hovered between them, undecided.
Min-ho glanced back. "Which way?"
Yuri scanned both paths. "No sound either direction."
Dae-sung crouched, running fingers across the stone.
"Tracks," he said, pointing left. "Fresh."
Park stepped toward the right. "Nothing here."
Min-ho looked between them. "So we go right."
Michael stayed still.
Too clean. Too empty.
He crouched near the right path.
Not tracks.
The dust had been disturbed, but not by movement. It was smoothed over.
Above the bend, the ceiling dipped inward slightly.
A hollow.
He stood. "Left."
Min-ho blinked. "The one with the monsters?"
"The one without them is worse."
Yuri followed his line of sight upward. Her expression tightened.
"…That's a drop."
Park nodded once. "They'd fall behind us."
Min-ho swore under his breath. "Fine. Left."
They descended.
The air shifted again, warmer now, heavy with moisture. Crystal light thinned out, replaced by faint patches of pale fungus clinging to the walls.
Visibility dropped.
At the next bend, Park lifted a hand.
They stopped.
A faint clicking sound echoed above them.
Not ahead.
Above.
Michael tilted his head.
The ceiling was layered with ridges and mineral growths.
One of them shifted.
Then another.
Crawlers.
Packed into the stone.
Min-ho lowered his voice instinctively. "How many?"
Michael counted movement instead of bodies.
"Fifteen. Maybe more."
Dae-sung glanced behind them. "We go back?"
Michael shook his head.
Too exposed.
He scanned forward.
A fallen pillar. Narrower section beyond. Lower ceiling.
Good enough.
"We move to the pillar," he said quietly. "Slow."
Min-ho nodded. "And if they drop?"
Michael adjusted his grip. "Then we hold."
They moved.
Measured steps. Controlled breathing.
The nest stayed still.
Until it didn't.
Min-ho's shoulder brushed the pillar.
A small sound.
Enough.
The ceiling came alive.
"Down!" Yuri snapped.
Crawlers dropped in a wave.
Michael fired immediately. Controlled bursts. No wasted shots.
Park stepped into the space he cleared, cutting two midair before they landed. Dae-sung worked low, catching anything that slipped through. Yuri pushed the center mass back with force blasts, breaking their rhythm.
Min-ho held the front.
The first impacts hit him together and stopped.
Michael pivoted left. "Wall!"
Park was already moving.
The fight collapsed into seconds of noise and motion.
Then it was over.
The survivors scattered deeper into the tunnel.
Silence returned.
Dae-sung exhaled. "Still alive."
"For now," Yuri said.
Min-ho checked his guard. "I'm starting to dislike caves."
"No," Michael said. "You're starting to pay attention."
That got a short laugh out of Dae-sung.
Park glanced at Michael once, then continued forward.
The path climbed.
Then opened.
The bridge chamber stopped them all.
A narrow span of stone stretched across a vertical shaft that disappeared into darkness. Blue crystals jutted from the walls below, their light swallowed before it reached the bottom.
Cold air rose from the depths, carrying a metallic edge.
Three sections of the bridge were gone.
Yuri stepped forward, looked down once, and stepped back. "No."
Min-ho leaned out slightly. "That's deep."
"Helpful," Dae-sung said.
Michael ignored the drop and focused on the gaps.
The first jump was manageable.
The second was longer.
The third ended in a broken edge.
Then he saw the wall.
Stone braces ran along the shaft in broken intervals.
A second path.
Park saw it too. "We don't use the bridge."
Michael nodded. "One at a time."
They crossed carefully.
Min-ho struggled, but made it.
Yuri moved more slowly, steadily.
Dae-sung crossed clean.
Park barely touched the surface.
Michael went last.
Halfway across, the bridge shifted.
A click.
He felt it through the stone.
"Move."
They did.
Black spears shot from the walls where the bridge forced alignment.
They hit empty air.
Yuri landed hard on the far side. "I hate this place."
"Good," Michael said. "It means you're thinking."
The next corridor was quiet.
Too quiet.
No tracks. No nests. No visible traps.
The marker pulsed brighter.
Close.
They slowed.
The passage opened into a circular chamber.
Smooth walls. No damage. No debris.
A pedestal stood in the center, holding a glowing crystal column.
Yuri exhaled. "That's it?"
Min-ho laughed once. "After all that?"
Dae-sung didn't lower his knives. "No."
Park scanned the walls. "Too clean."
Michael didn't look at the pedestal.
He looked at the room.
No exits except the one behind them.
High walls.
Minimal cover.
He stepped forward just enough to confirm.
"Don't touch it."
Yuri paused. "Why?"
"Because this isn't the end."
The marker pulsed again.
Behind them, stone dropped.
The entrance sealed shut.
Min-ho turned. "That's new."
A second wall sealed on the opposite side.
The floor lit up.
Thin lines of blue energy spread outward from the pedestal.
Every interface chimed.
System message received.
Michael's HUD flared.
Sector survival challenge initiated.
Openings began to slide open along the upper walls.
Min-ho looked up. "…You've got to be kidding."
Michael raised the SMG.
"No."
The crystal brightened.
"This is the part that matters."
