The creature SCREAMED.

  Not a sonic attack. Just pain. Pure, shocked, agonized pain. A sound that echoed through the chamber like nothing that should exist.

  It jerked backward. Stared at its forelimb.

  Where the blade had touched, flesh had flash-frozen. Tissue crystallized in an instant, turning black and dead even as Arthur watched. The wound didn't bleed—the blood was ice before it could flow. And the frost was spreading, creeping outward from the contact point, thermal shock shattering cells.

  The creature's regeneration wasn't working. Arthur could feel it trying through the resonance—the Gener physiology attempting to repair the damage. But the cold was too complete. The frozen tissue was beyond recovery.

  Permanent damage. From a single glancing blow.

  The creature's six pale eyes fixed on the Cryo-blade with new understanding.

  the resonance acknowledged. Fear colored the impression now.

  Its tactics changed instantly. No more testing. It circled wider, maintaining distance, treating the blade like the mortal threat it had proven to be.

  Arthur reset his stance. His ribs were already healing. His shoulder wound had closed.

  One lesson learned by each of them.

  * * *

  What followed was not a fight. It was a negotiation conducted in violence.

  The creature wouldn't close with Arthur anymore. Every time he advanced, it retreated. Every time he swung, it circled away. The Cryo-blade had become a barrier—a frozen threat it refused to test again.

  But Arthur couldn't win by defense. He needed to land hits. And the creature was faster than him, more experienced, reading his patterns before he knew he had patterns.

  They circled. Minutes stretched into something that felt like hours. Arthur attacked; the creature evaded. The creature probed; Arthur presented the blade.

  Behind them—too far away to help—Dren remained slumped against the spire. The seizing had stopped, replaced by utter stillness. Unconscious, maybe. Or worse. Arthur couldn't check. Couldn't afford to take his attention off the creature for even a second.

  Stella was still moving. He could hear her—the scrape of synthetic limbs against stone, the spark of damaged systems, the trail of fluid she was leaving behind. Closer to the weapon. Closer to giving them a chance.

  , the resonance observed.

  Arthur's grip tightened on the blade. "Try it."

  Something like amusement.

  The creature feinted left. Arthur swung. It darted right—

  Claws raked down his back. Deep. Through muscle, grazing bone.

  Pain exploded through his system. His regeneration responded immediately—crystals spreading, tissue knitting—but the damage was real. And regeneration cost energy.

  The creature retreated before he could counter.

  , the resonance observed.

  Arthur was breathing hard now. Not from exertion—his enhanced physiology could handle that. But the constant healing was draining him. Every cut that closed, every wound that sealed, burned through reserves he couldn't replace down here.

  The creature was patient. It could do this for hours.

  Arthur couldn't.

  , the resonance noted.

  The creature's eyes moved past him. Toward Stella, who was almost at the weapon now. Toward Dren, motionless against the spire. Toward the things Arthur was trying to protect.

  It moved.

  Not toward Arthur. Past him. A blur of black and blue that exploded through the gap his last swing had created.

  Toward Stella.

  Toward the Hand Cannon she was almost close enough to reach.

  * * *

  Arthur ran after it. Too slow. Always too slow.

  He burst into the junction area—and found Stella.

  She'd reached the Hand Cannon. Her damaged hand clutched the weapon, synthetic fingers locked around the grip through sheer determination. She was on her back, the barrel tracking toward the creature as it emerged from the passage.

  At ten meters, she didn't need perfect accuracy. Didn't need functioning motion prediction. Just point and shoot.

  She fired.

  Stolen from its original source, this story is not meant to be on Amazon; report any sightings.

  BOOM.

  The creature twisted. The shot went wide by centimeters—close enough that Arthur saw the thermal bloom sear across its hide. Close enough that it felt the heat of what would have killed it.

  Close enough to make it very, very angry.

  Stella was already trying to track for a second shot—

  The creature was faster.

  It crossed the distance in a heartbeat. One swipe—precise, surgical—at the weapon rather than the wielder. The Hand Cannon was torn from her grip with force that cracked synthetic components. Arthur heard something in her arm break.

  The weapon spun away. Clattered against the tunnel wall. Slid into shadows.

  Then the second swipe.

  Across her torso. Through the damage that was already there. Widening it. Deepening it. Claws sheared through systems that were already failing, found new ones to destroy.

  Stella's body arched with the impact. Synthetic fluid sprayed. Something inside her sparked and died. She collapsed, body twitching as cascading failures ripped through her systems.

  Arthur saw her fall. Saw the spray of silver fluid. Saw her eyes—still conscious, still aware, still tracking him even as her body stopped responding.

  Again.

  He'd failed again.

  The thought was cold. Clear. Familiar.

  She was thrown through a window and he couldn't stop it.

  Now she's broken on the ground and he couldn't—

  Something in Arthur snapped.

  The barrier he'd built between himself and the thing growing inside him. The wall he'd constructed to stay human, to stay , to not become the monster.

  It crumbled.

  What rushed through the gap wasn't rage. It was something colder. Something that had been waiting in his blood since his DNA had been altered.

  , Arthur thought at the creature. Not words anymore. Something more direct. More primal.

  The resonance between them pulsed with surprise.

  Arthur attacked.

  * * *

  He didn't think. Didn't plan. The Cryo-blade was in his hand and he was moving, closing the distance, screaming something that wasn't words.

  A thought tried to form—something about tactics, about the blade—

  Gone. Burned away by something other than thought.

  The creature turned to face him. It knew the blade. It could dodge—

  Arthur didn't swing.

  He threw himself at it. Body and blade together. Not technique. Not strategy. Just collision. Just violence. Just the absolute refusal to let this thing take anything else from him.

  The creature tried to evade. But Arthur wasn't attacking where it was. He was attacking where it was going to be. Some instinct he didn't know he had, some pattern recognition his changing brain had developed, let him read its movement before it completed.

  He slammed into the creature. They went down together, rolling across the stone floor in a tangle of limbs and claws and frozen edge.

  The creature tore at him. Claws opened his arm from elbow to wrist. Ripped across his chest, laying ribs bare. Scored his face, narrowly missing his eye.

  Arthur didn't stop. Couldn't stop.

  The wounds sealed even as they were being made. Crystalline growth spreading from his spine across his body, covering exposed muscle, armoring vulnerable points. Aurora light flickered beneath his skin—the same light that had terrified him in the facility. The same light that meant he was becoming something else.

  He didn't care anymore.

  , he told the creature through their resonance. Not words. Something more direct.

  The creature thrashed beneath him. Its remaining functional limbs tried to gain leverage. Tried to throw him off.

  Arthur held on. And the Cryo-blade found flesh.

  He drove it into the creature's side. Deep. Through hide, through muscle, toward organs.

  The frost spread from the wound like infection. Tissue freezing. Cracking. Dying. The creature's bioluminescence flickered and failed in the frozen zone, cells crystallizing, life draining away.

  The creature screamed. That awful sound again—pain beyond anything it had ever experienced. Its body convulsed, trying to regenerate, failing against the absolute cold.

  It threw Arthur off with desperate strength.

  He hit the tunnel wall. Ribs cracked. They knit.

  The pain was distant. Something happening to a body that wasn't quite his anymore. He registered the damage and watched new crystalline formations spread to support the healing.

  The creature stared at him with those six pale eyes. Blood—frozen blue blood—oozed from the wound in its side. The frost was still spreading.

  The resonance carried genuine fear now.

  Arthur rose. Cryo-blade in hand. Frost trailing from an edge now stained with frozen blood.

  He smiled with teeth that weren't entirely human anymore.

  "You wanted to see. Now you know."

  * * *

  Arthur charged.

  He swung the blade in wild arcs. No pattern. No rhythm. Just relentless aggression. Every movement designed to close distance, to force contact, to make the creature pay for everything it had done.

  The creature tried to retreat. Wounded badly now. One forelimb frozen and useless. Deep wound in its side that wouldn't stop spreading, frost eating deeper with every second. Its movements were slower, favoring the damaged flank.

  But Arthur wouldn't let it escape.

  He threw himself after it, blade leading, teeth bared.

  The creature struck back. Claws opened his left arm from shoulder to elbow—a wound that exposed muscle and bone, that should have dropped him screaming.

  He didn't feel it. The crystals were already growing, sealing the wound, armoring what had been vulnerable. His left hand kept working. The blade kept moving.

  Another exchange. The creature feinted for his face; he ducked; its tail—he hadn't noticed the tail before—whipped around and caught him across the chest. He flew backward, hit a spire, felt his spine crack against the calcium structure.

  He was up before the pain could register. Moving again. Attacking again.

  the resonance screamed.

  This was hunting. This was what Arthur had become when he stopped thinking and started being.

  The creature retreated. Wounded badly now. One forelimb frozen and useless. Deep wound in its side that wouldn't stop spreading, frost eating deeper with every second. Its movements were slower, favoring the damaged flank.

  But it was still faster than Arthur. Still more experienced.

  And it was afraid.

  The resonance between them pulsed with the creature's growing alarm. Arthur's signature was changing—growing stronger, more complex. The crystalline formations spreading across his body weren't just healing anymore. They were adapting. Optimizing. Turning him into something designed for this fight.

  Something evolving toward what the creature was.

  Or beyond it.

  The creature struck back. Desperate now, abandoning careful tactics. Claws raked across Arthur's stomach—a wound that should have been fatal, should have spilled his intestines, should have ended the fight.

  The wound sealed before his insides could escape. Crystals grew across his abdomen like armor, protecting what had been vulnerable.

  Another strike. Through his shoulder. The blade dropped from fingers that stopped working.

  Arthur caught it with his other hand. The wounded shoulder was already knitting, crystals spreading to support the damaged joint.

  the resonance carried something like desperation.

  Arthur didn't answer with words. He answered with the blade.

  Another cut. Across the creature's haunches. Frost spreading instantly, freezing tissue, killing nerves. Its back legs faltered.

  It screamed. Tried to retreat. Arthur followed.

  Another cut. Across its remaining functional forelimb. The creature crashed to the ground, three of four limbs now compromised.

  Arthur stood over it. Cryo-blade dripping frozen blood. Crystals covered half his body—not quite armor, not quite skin, something in between. His eyes, when he caught their reflection in the creature's pale orbs, glowed with aurora light.

  The resonance between them pulsed with mutual recognition.

  Arthur thought.

  the creature agreed. Pain and fear and something like respect colored its response.

  Arthur raised the blade for the killing strike.

  The creature's six pale eyes fixed on him. On the blade. On the end that was coming.

  Then it made a decision.
