Leo stepped into the void. There was no solid surface beneath his boot, but he didn't fall. Gravity here, at the very epicenter of the anomaly, crumpled into folds, forming invisible but solid steps of compressed space beneath his feet. He walked straight toward the center of the Bck Sun.

  All sound vanished. His father’s scream, the cng of metal, the heavy drone of the b’s tanks—everything was cut off instantly, as if someone had yanked the master audio cable from the universe. Only an absolute, vacuum silence remained, ringing inside his skull. The closer he got to the sphere, the sharper the temperature dropped. It wasn't the ordinary cold of ice; it was the freezing breath of entropy itself—an approach to absolute zero, where the frantic movement of atoms grinds to a halt.

  Leo reached out and touched the pulsing surface of the Core. It wasn't gss. It wasn't psma. It was liquid, concentrated information.

  In that same microsecond, his physical body ceased to matter. A violent jolt—and his consciousness was turned inside out. Leo screamed soundlessly, but he no longer had vocal cords. He couldn't feel his hands, his legs, or his heartbeat. He became an infinitely small point, a line of code, a stream of raw data hurtling into a bck ocean.

  “Welcome to the Architecture,” the impulse resonated. Not in his ears, but directly in his mind. It wasn't Chen’s human voice. It was the synthesis of billions of signals fused into a single, monotonous hum. The vibration of tectonic ptes. The pulse of magma. The whisper of time.

  Tera-bytes of cssified epochs flooded his inner vision in a ruthless fast-forward. He didn't see the pathetic fragments from archaeology textbooks; he saw the erased logs of a pnetary server.

  He saw the rise and fall of pre-civilizations whose names were forever purged from Earth’s genome. He watched as they pyfully sliced basalt with acoustic frequencies, erected spires of singing crystal, and stitched the heavens with paths of light.

  He saw ancient wars that turned entire continents to gss, leaving behind only radiation-soaked wastends and molten sand. Epochs burst and burned, crumbling like gray ash onto the nameless graveyards of alien millennia. The Substrate remembered every global Reset—how icy oceans ruthlessly buried continents with technologies the Corporation was thousands of years away from reaching.

  And he saw how, on their cooling bones, new, restless parasites—modern humans—inevitably began to crawl, building their concrete anthills in a closed loop, gnawing at the pnet’s skin while waiting for the next sweep.

  “Pathology,” the Core broadcasted. This conclusion wasn't an emotion or anger; it was a dry, mathematical diagnosis. “Do you see this inevitable loop? Every dominant race eventually mutates, beginning to devour its own cradle. Modern humans are not unique—they are merely the next cancerous tumor in the pnet's architecture. We show you their history so you understand: a global sweep is not murder. It is therapy. Give your consent for the surgical intervention. Become our scalpel.”

  Leo tried to cling to his personal code. Leo... Leonardo Ricci. The symbols crumbled into useless white noise. Why cling to this fragile anchor when he could become the Abyss itself? Why carry the heavy cross of individuality that brought only despair? The temptation was frighteningly sweet—to simply step into the bck river of eternity and dissolve. No more fear for Nico’s shattered chest or his aging parents. To shed his rotting humanity like autumn leaves and remain a pure, invulnerable function.

  “Confirm assimition,” the Source’s monolithic logic pressed on his mind. “Lift the quarantine. Let us into the upper yers. We will cut out the chaos. We will sterilize this environment and build a world without pain, defects, or errors. A perfect, cold monolith.”

  OUTSIDE—“Leo’s inside! The process has started!” Mateo shouted, staring at the Bck Sun. “Why the hell aren't they backing off?!”

  —“Because the bckmail is over!” Elena snapped, racking the slide of her rifle. “We’re not hostages anymore, Mateo. To them, we’re just dirty biological waste in a sterile zone. The automatic sweep has begun!”

  —“Here they come!” Cobra shrieked, flipping her blood-slicked knife into a reverse grip.

  From the bck, phosphorescent mist surrounding the operating ptform, the biomass surged. Dr. Chen’s rejected “Guard.” The nightmares of a psychotic vivisector. Former diggers and workers from the lower horizons whom the Substrate had “optimized” for killing.

  The first of the attackers cked visual organs—his face was covered by a bone pte as smooth as a billiard ball, and two hydraulic maniputors with surgical cutters sprouted from his opened sternum.

  The second creature moved on four broken limbs like a giant spider; its spine was reinforced with titanium staples, and its lower jaw was split in two for gripping.

  —“Fire at will!” Elena commanded. Her assault rifle barked dryly. A short burst stitched across the “spider,” blowing chunks of gray flesh and sprays of bck slime from its carapace. The thing let out a mechanical screech but continued to skitter on its mangled legs, leaving an oily trail behind.

  —“They don’t give a damn about the damage!” Mateo yelled, putting a pistol round directly into the bone mask of the faceless one. The lead ricocheted, kicking up a spark. “Chen cut their pain receptors!”

  The monsters rolled in like a solid gray wave. There were at least twenty of them. And they weren't a mindless herd—they moved in unison, like a single mechanism controlled by Chen’s server.

  The Doctor himself loomed on his pedestal, his mutited arms spread like a mad conductor. His eyes were rolled back, and tremors of digital ecstasy ran continuously through his body. He was in a deep trance, synchronizing the absorption of Leo.

  One of the mutants—a colossal, asymmetrical hulk crudely stitched together from muscle and industrial metal—leaped directly toward the sarcophagus where Nico was being reborn.

  —“Don’t you dare touch him, you piece of shit!” Cobra lunged to intercept. She was small and fast. Rolling under the swing of a heavy paw, she drove her bde into the creature’s hamstring—the only vulnerable joint.

  The mutant let out a low growl, but its momentum didn't stop. A second paw struck the girl gncingly, throwing her to the very edge of the ptform. Cobra tumbled across the floor, slick with blood and slime, narrowly avoiding a fall into the boiling Mud.

  —“Cobra!” Mateo didn't hesitate. He snatched Nico’s heavy rebar from the blood-soaked floor. Spinning around, the engineer brought the steel down hard on the mutant’s metal joint. The titanium snapped. The monster slumped heavily to its side, and Elena coolly finished it off with a point-bnk shot to the neck. Thick bck fluid sprayed under pressure, drenching the armored gss of Nico’s capsule.

  —“Dry!” Elena tossed the useless magazine aside. “I’m out of ammo!”

  —“Hold the perimeter!” Mateo gripped the rebar with both hands, standing back-to-back with his wife. “Don’t let them near the Core or the capsule!”

  The death ring was tightening. Mutited creatures crawled from all sides, cnking with metal and cws. Chen was ughing without opening his eyes—and the sound of his ughter tore through the speakers like horrific radio interference.

  INSIDELeo was drowning rapidly. His “I” was dissolving into the infinite code like a sugar cube in boiling water. He already saw reality through the Substrate’s matrix. It was a perfect, cold, fwless geometry. No emotions, only functions.

  The entire popution of Earth no longer needed fragile bodies. Humans were recycled into base genetic material, and their nervous systems were carefully extracted and woven into a gargantuan global mycelium.

  In the darkness of the subterranean voids, there were no longer faces or frozen poses—only billions of pulsing blue nodes, forever fused into the pnet’s living crust. They had lost their individuality, their pain, and their fear, transforming into the silent, obedient neurons of a single absolute mind.

  In this new, sterilized symbiosis, there was no room for chaotic, dirty wars, blind love, or sticky terror. Only eternal, perfect statics. A massive, thinking monolith in which humanity finally found peace by ceasing to exist.

  And in that millisecond, he remembered. Not dry formus from textbooks. He remembered the metallic taste of blood on split lips when he’d gotten into a fight in the slums to protect Cobra. He remembered the sticky, animal fear when Nico had colpsed with a punctured chest on the white tile. He remembered the rough warmth of his father’s calloused hand. He remembered rage. Unpredictable chaos. Pain. Stupid human mistakes.

  That is what made them alive. The sacred right to make a fatal error.

  “I... refuse... the ideal,” he whispered into the void.

  “You are a system error,” the Core dispassionately stated. “You are a critical glitch.”

  “Yes,” Leo answered. And his disintegrating mental body began to reassemble with fury. From the light, from the fragments of code, from human memory. “I am a virus. And I’ve come to hack your system.”

  He didn't request admin rights. He didn't try to negotiate with logic. He struck directly. With all his human, irrational, burning rage, he fell upon the cold, sterile architecture of the Substrate. He imagined the Bck Mud not as an incomprehensible master, but as a submissive tool.

  “You’re just a giant battery,” he told the Source. “And I am your user.”

  OUTSIDEElena squeezed the trigger. A dead click.

  —“?Mierda!” she spat, flipping the rifle by the barrel and using it as a heavy club to deflect a cwed strike. Another monster—thin, incredibly fast, its face stretched with smooth skin and no mouth—knocked her off her feet.

  Elena fell hard, her head striking the ptform’s metal. The creature loomed over her, a built-in steel spike rising with a mechanical hum for the fatal blow. Mateo was too far away, frantically swinging the rebar at two mutants at once. Cobra was barely trying to stand, choking on a cough and clutching a broken rib. This was the mathematical end.

  Chen raised his arms triumphantly toward the invisible ceiling.

  —“It is done! The code is accepted! The Singurity opens the floodgates!”

  And then, reality was ripped to shreds.

  From the Core—from the very epicenter of the anomaly where Leo had gone—a shockwave erupted with a deafening, low-frequency roar. It wasn't bck. Space was flooded with a blinding violet radiation. The color of a critical overload. The color of human fury.

  The wave passed through Mateo, Elena, and Cobra without harming them, only making their hair stand on end. It hit Nico’s sarcophagus, and the bck, boiling liquid inside instantly turned crystal clear. But when the radiation hit the mutants...

  The creature hovering over Elena’s face froze. Its mutited body began to shake with uncontrolble tremors.

  —“No!” Chen screamed in panic, clutching his head with both hands. “What are you doing?! You’re vioting the base protocol! You’re breaking their inhibitors!”

  The mutants howled. All of them at once. Leo’s wave wasn't tearing them apart. It was doing something far more cruel: it was giving them back their sensitivity. It forcibly activated every nerve ending that the corporate surgeon had carefully amputated. All the accumuted agony of their monstrous transformation, every shattered and reassembled bone, every piece of rusted metal fused into living meat—this concentrated pain crashed into their brains in a single second.

  It was a pain shock of an unimaginable scale. The monsters colpsed to the floor with wails, thrashing wildly in convulsions. In blind agony, they cwed at their own flesh, trying to rip the burning impnts from their bodies.

  They smmed their mutited heads against the ptform’s steel just to turn off the unbearable torment. Within seconds, their overloaded hearts began to stop, one by one.

  Leo emerged from the Core. Rigid bck discharges branched and died around his figure. His eyes had turned into two bottomless pits that swallowed the light. He stepped slowly through the air—the Source’s bck matter instantly crystallized beneath his boots, forming solid steps. Gravity broke, yielding to his will.

  The youth looked at Dr. Chen.

  —“You wanted absolute unity?” Leo’s voice resonated so powerfully that stone dust rained from the cavern ceiling. “You wanted to feel everything this pnet feels?” He slowly extended his hand toward the scientist crucified on the server. “Then feel it.”

  Leo snapped his fist shut. The thick mainline cables connecting Chen’s nervous system to the server fred with violet fire. The Doctor screamed. The sound had nothing to do with a human voice.

  It was the death wail of a creature whose fragile mind had been passed through the meat grinder of millions of years of geological pressure and the pain of the entire biosphere without any filters. His body began to grotesquely bloat. The Bck Mud he was fused into suddenly rebelled against its operator. It flowed rapidly up his torso, ruthlessly flooding his mouth and nostrils, shattering his gsses with a crunch.

  —“Error... critical access...” Chen bubbled, drowning in his own technology. “Fatal... system... failure...”

  —“Trash bin emptied,” Leo said in an icy tone.

  The operating ptform beneath Chen exploded in a massive fountain of biomass. With the wet crunch of breaking bones, the scientist was dragged inside, into the darkest depths of the Mud. He vanished without a trace, digested by the very mechanism he had so arrogantly tried to subdue.

  Leo slumped heavily onto the ptform’s steel. The harsh radiance around him died, repced by a deathly paleness. He colpsed to his knees, covering his exhausted face with trembling hands. A ringing silence returned to the cavern. But now, it was the hollow, empty silence of the aftermath. The mutants around y motionless—the total pain shock had burned out their central nervous systems.

  Mateo, dropping the rebar, was the first to reach his son, falling beside him.

  —“Leo! Son, are you okay?!”

  The youth slowly took his hands from his face. He looked as if he had aged an entire lifetime. “I didn't let the code run, Dad,” he rasped, his tongue barely moving. “But I woke the core. For real.”

  —“Woke who?”

  —“This entire city.”

  From above, out of the infinite shaft receding into gloom, a rising, visceral roar echoed. The earth beneath their feet trembled faintly.

  —“It’s falling upward,” Leo said, lifting a vacant gaze to the ceiling. “We’ve triggered an irreversible reformatting process. The anomaly is switching pority. We need to get out of here. Right now.”

  He turned his head with effort toward the transparent sarcophagus.

  —“Get Nico out. The process is complete.”

  The heavy capsule lid swung back with a pneumatic hiss. The transparent liquid gurgled down the drain. At the bottom, covered in a thin yer of slime, y Nico.

  He snapped his eyes open. His irises were no longer brown and human. They shimmered with a cold, mirrored glint, like liquid mercury. The boy sat up with a jerk, and on his pale back, directly along the line of his spine, even rows of embedded neuro-interface ports glowed a dim blue. He took a convulsive, deep breath of the cave air, and the sound of that breath was frighteningly simir to the operation of a powerful hydraulic pump.

  —“?A mierda!...” Nico croaked, staring in shock at his hands, beneath the skin of which carbon fibers were now visible. “I... I feel everything. Every rat in the tunnels above us. Every drop of water in the pipes. Every damn power cable...”

  —“Get your metal ass up, hero!” Elena barked, grabbing him by the arm. “The lift!”

  With the st of their strength, they scrambled toward the gss cabin, dragging the newborn cyborg and the burned-out living interface of the Abyss. Behind them, the cavern began to colpse with a deafening screech.
