Reborn As The Last World Cat-Chapter 56: ScarMandible’s Gambit

The centipede announced itself by breaching the ground.

Kai felt it first—an off-beat vibration in the rock, wrong against his pressure sense. Not a quake. A body. Something huge that made earth behave like water.

Scout felt it three seconds later. Her pheromone markers went razor-sharp.

"Multiple limbs. Following the main water channel. It’s not hunting randomly."

Silence fell in that way reality does right before it breaks.

Kai’s genetic memory spiked into static. The ancestral voice that had been rising since the carved warnings now screamed until his thoughts scattered.

Predator. The kind the stones drew with too much detail. The kind you only draw that well if you watched it hunt and lived long enough to regret it.

Twenty-three reached Rally Point Alpha in minutes. Kai counted without choosing to.

Twitchy. Bitey. Whisper. Dig. Current. Guardian. New fighters. Builders from three weeks ago. Young kits who’d never faced anything bigger than a shove.

Not enough.

He pushed that thought down.

"Distance?" he asked.

Scout unrolled maps. Claws traced channels with the confidence of someone who had slept on schematics for months.

"Under two kilometers. Maybe much less. It isn’t just traveling through water—it’s using it. The pressure pulses are deliberate. It understands the system."

Current edged closer. Three weeks old. Already learning how late knowledge can arrive.

"Can we collapse the channels? Block it?"

"With what?" Dig said, calculating. "We don’t have thirty minutes to engineer a collapse that holds."

Whisper layered a dense marker.

"Distributed nervous system. If it hunts like the stones show, no single kill point. Segments coordinate."

"So we don’t try to kill it," Bitey said, voice calm in that stillness before the first strike. "We survive it. Defend what we can. Accept what we can’t."

Kai had a speech. What left his mouth was simpler.

"We defend."

The word landed like weight. Not a vote. A sentence.

Twitchy’s checking loop accelerated—one, two, three, claws ticking on stone.

"Young kits move. North passages. Guardian, evacuation. Whisper, markers on every turn. Current, get non-combatants moving."

Guardian didn’t answer. He moved. Authority didn’t need words. Already massive, growing into a strength that bent air.

The "roar" that followed wasn’t sound.

It was vibration deep enough to make stone scream. Kai’s pressure sense blew out under the force—a tide he couldn’t parse.

The centipede slid into the upper chamber.

Eighty meters at least. Maybe more. Counting stopped being useful.

Segmented body. Overlapping plates flashing fungus-light like living armor. Limbs too many to count at a glance—each thick as a kit’s torso, each ending in claws that treated rock like bark.

The head was a blueprint for nightmares.

Concentric jaws, each ring able to crush bone by itself. Eye clusters along the anterior segments, tracking everything with cold interest. Venom beading on specialized fangs—so thick Kai could taste the poison in the air.

No one moved.

It didn’t rush. It placed itself with deliberate precision. Not hunger. Study. Measurement. Choice.

Instinct screamed at Kai to charge. The predator in him agreed. The ancestral voice roared along.

Don’t panic. Don’t break. Command.

"Hold position," Kai marked, sending crisp authority through the chamber. "Do not engage. Let it move."

The head turned toward him. Curious.

Three seconds stretched long enough to fold a lifetime inside them.

Venom sprayed.

The cloud boiled out too fast. Not reflex—calculation. Bitey leaped clear. Hunter-One—a new combat kit—stepped straight into the path.

The scream cut everything.

Chitin dissolved. Flesh burned. A mind learned, too late, that experience wasn’t enough.

Hunter-One collapsed. Limbs thrashed. A piece of Kai’s internal arithmetic cracked in two.

"Formation three!" Kai barked. His voice sounded far away. "Use the dispersal—closer to the body it thins."

The centipede lunged.

Not at Kai. At Dig.

The builder was closest to the anterior plates. The jaws opened and the rings of teeth worked like a machine.

Dig tried to dodge. Strong. Not fast.

A side mandible clipped his rear leg. The crack sounded like splitting rock.

Dig screamed once. Went down.

Kai moved on instinct. Not to Dig—toward the left flank.

His claws hit armor and bounced like bedrock. The rebound slammed him into the wall. Pain lit his ribs like fire.

The centipede didn’t look at him. There were other targets. More meat.

Bones flexed—and knit.

The regenerative system he’d taken weeks ago surged. Fractures closed. A gouge across his shoulder sealed to a line. It burned through calories he didn’t have and energy he couldn’t spare.

Survive.

Kai forced himself up.

Twitchy became a machine. Routes marked safe, unsafe, borderline. Eastern corridor shut down clean. The paranoia loop turned into a throughput algorithm that saved lives.

Whisper kept dropping markers—warnings, paths, live notes no one could read right now.

Current shepherded the smallest. His voice stayed steady.

"This way. Low. Keep moving. Don’t look back."

Scout didn’t move.

She wasn’t frozen by fear. She had the look she wore when patterns clicked. Her whole body tracked the centipede’s glide, noting micro-corrections in limb placement, the way pressure ripples fed back into each stride.

"It’s using the channels," she breathed. Then louder, "It’s navigating by the water. That’s—"

A rear limb swept with casual, absolute power.

Scout dodged the wrong way—predator reflex instead of calculated escape.

Impact. Rigid. Limp. Eyes gone distant the way bodies do when minds step out.

"Scout!" Current screamed, the sound breaking, and lunged.

Bitey caught him by a rear leg and hauled him back. Helplessness crossed Bitey’s face like an eclipse.

Something broke in Kai’s chest that had nothing to do with ribs.

Scout had been the mind of water. Months of maps. The questions that mattered.

She was gone because his prep had weighted fighters and exits over the truth she alone understood—some predators hunt like rivers.

He’d told her to stay. She’d trusted him.

Move.

"North passages!" Kai ordered. The authority held. Something under it didn’t. "Now!"

Current screamed until the scream wore out. The quiet after hurt worse.

The colony flowed in fragments.

Bitey under Dig’s shoulder. Guardian driving the smallest forward without mercy, because mercy wouldn’t breathe tomorrow. Twitchy doing math with his eyes—losses, odds, routes.

The centipede didn’t chase. 𝗳𝗿𝐞𝕖𝘄𝗲𝕓𝗻𝚘𝚟𝕖𝐥.𝚌𝕠𝕞

It coiled in the main chamber like planting a banner. Objective achieved. Position taken. One fighter dead. Capability demonstrated.

The ancestral voice shifted key.

Extinction isn’t one blow. It’s catastrophe plus predation. Not one enemy—an ecosystem feeding while the ground turns traitor.

They poured into the northern tunnels. Kai took rear guard. Breath ragged. Regeneration scalding, scraping for resources. Moving anyway.
