Chapter 1 CHAPTER ONE
The smell hit Adrian before the screaming did.
Rotten meat mixed with wet concrete drifted through the underground station so suddenly that people began covering their noses almost at the same time. A woman near the ticket machines cursed under her breath while another passenger complained loudly about dead rats in the tunnels. Somewhere farther down the platform, a child started crying.
Adrian barely looked up from his phone.
His shift at the morgue had ended less than thirty minutes ago, and exhaustion still clung to his body like cold water. The gray sleeves of his work uniform smelled faintly of bleach and formaldehyde, and his shoulders ached from moving bodies all day. All he wanted was to get home, shower, and sleep for twelve hours straight.
The station lights flickered once overhead.
Nobody reacted.
Power outages happened often enough.
But then the lights flickered again, longer this time, and the digital arrival board suddenly went black. A low murmur spread through the crowd as commuters glanced around irritably.
The station speaker crackled. “Attention passengers, due to an unexpected
Static swallowed the rest.
A deep vibration rolled beneath the floor.
Adrian frowned slightly as the metal railing beside him trembled under his hand.
Then came the second vibration.
Stronger.
Hard enough to shake dust loose from the ceiling.
Several people stumbled. Someone laughed nervously. A businessman near the edge of the platform muttered something about an earthquake, but the unease spreading through the station felt wrong. Earthquakes didn’t feel alive.
Another tremor slammed upward from beneath the tracks.
The tunnel ahead darkened completely.
Not because the lights failed.
Something inside it blocked the light.
Adrian narrowed his eyes, trying to see through the darkness, when a man suddenly burst through the emergency stairwell at the far end of the station.
He was covered in blood.
“Run!”
The scream ripped through the station hard enough to silence everyone else.
The man collapsed face-first onto the platform, sobbing violently as blood poured from deep claw marks across his back. One side of his face looked peeled open, strips of flesh hanging loose as he clawed desperately at the ground.
“There’s something down there,” he choked out. “Something’s eating people”
The station exploded into panic.
People surged toward the exits instantly, shoving each other hard enough to send bodies crashing into walls and railings. A woman fell near the stairs and disappeared beneath the crowd before anyone stopped to help her.
Adrian got shoved sideways into a support pillar as screams erupted across the platform.
Then the tunnel moved.
Concrete bulged outward slowly like skin stretching beneath pressure. Cracks split across the walls while thick black fluid leaked from the openings in heavy streams. The sound that followed made Adrian’s stomach twist.
Breathing.
The station was breathing.
The lights died completely.
Darkness swallowed everything for half a second before emergency lights flickered on overhead, flooding the underground in a dull red glow.
That was when the walls opened
The concrete peeled apart in twitching layers, exposing wet flesh underneath. Veins pulsed through the station walls. Thick tissue spread across the tracks like cancer growing in real time, swallowing metal and stone alike.
People screamed harder.
A glowing blue screen suddenly appeared in front of Adrian’s eyes.
[WORLD INTEGRATION INITIATED]
His breath caught.
More windows exploded into existence all around the station, hanging in the air like transparent holograms.
[Earth has entered Trial Ecosystem #8841]
[Survive]
“What the hell is this?” somebody shouted.
The floor split open before anyone could answer.
A woman near the tracks vanished instantly as the ground beneath her collapsed. Her scream echoed upward for only a second before it ended abruptly with a wet crunch from somewhere below.
Blood sprayed from the crack.
The crowd lost whatever control it still had.
People climbed over each other trying to reach the exits while security guards screamed useless instructions nobody followed. Adrian’s heart hammered violently as another system message appeared.

[Survive: 30 Minutes]
[Reward: Continued Existence]
[Failure Penalty: Death]
Something long and pale slithered out from the torn tunnel wall.
Adrian froze.
The creature resembled a centipede stitched together from human remains. Multiple mouths opened and closed across its body while too many legs scraped violently against the concrete floor. One of its heads lunged sideways into the crowd and bit straight through a man’s torso.
The body came apart instantly.
Screams erupted everywhere.
The creature dragged half the corpse backward while chewing loudly, blood splattering across the station floor in thick streams.
A teenage boy slammed into Adrian from behind, shaking so badly he could barely stand. “Please,” he gasped. “Please help me—”
Another creature dropped from the ceiling.
This one was smaller, white-skinned and hairless, its limbs bent at impossible angles as it landed directly on a screaming woman. Its claws punched through her stomach before she could even react.
Adrian grabbed the boy’s arm hard. “Move!”
The main exits were death traps now. Too many people. Too much panic.
He shoved open a maintenance door near the employee corridor and dragged the boy inside just as another tremor ripped through the station behind them.
The hallway smelled damp and rusted. Emergency alarms screamed overhead while distant sounds of tearing flesh echoed through the walls.
The teenager stumbled beside him, crying openly now. “What’s happening?”
Adrian didn’t answer because he didn’t know.
But he understood one thing clearly.
This wasn’t random.
The system messages.
The creatures.
The breathing walls.
This had been prepared.
The corridor suddenly twitched.
Adrian stopped walking immediately.
Veins spread beneath the paint like roots growing under skin. The walls pulsed slowly around them.
The boy noticed too and let out a terrified sound.
Something crashed through the ceiling.
The creature landed directly on the teenager.
Claws ripped across the boy’s throat before Adrian could react. Blood sprayed across the hallway walls while the creature shrieked violently, its mouth opening far wider than anything human should.
The teenager collapsed choking on his own blood.
Adrian’s body moved before his mind did.
He grabbed a broken metal pipe lying beside the wall and swung with everything he had.
The pipe slammed into the creature’s skull with a sickening crack.
It screeched and lunged at him wildly.
Adrian swung again.
And again.
Black fluid burst across his face as the creature’s head finally caved inward.
Its body twitched violently on the floor before going still.
Silence filled the corridor except for Adrian’s ragged breathing.
Then another blue screen appeared in front of him.
