Chương 126: The City’s Lungs (1)

The cathedral doors were no longer doors. They were meat. Two colossal slabs of living flesh stood before them like the ribs of some buried giant, slick and glistening beneath crimson light leaking from wounds in the ceiling. The surface pulsed in slow contractions, damp and intimate, like the throat of something trying to breathe through a body too large for the world around it. Chhk… chhk… Each pulse came with a wet sound. Each exhale felt too human.

The air reeked of blood, ozone, and something sweet enough to turn the stomach. Not perfume. Not incense. Something worse. The sweetness of sanctity after it rotted. Underneath it all was another scent. Sharp. Metallic. Almost electric. Old Prime Flux contamination. Not the clean, measured kind used in Crimerian reactors or military equipment. This was raw residue soaked into flesh, prayer, blood, and three centuries of sealed decay. It clung to the air like invisible ash. John stopped a few steps away.

His voice came out thin and cracked.

"This… is the door." Z-69 said nothing at first. The violet crystal in his chest cast a faint reflection across the slick flesh, and in that light the thing looked even less natural. Not organic. Not mechanical. Something in between. Something that had spent too long evolving without permission.

"To me," Z-69 said at last, "it looks more like a mouth." He placed his palm against it. The flesh gave under his touch. Warm. Slick. Waiting. The surface shivered. Something beneath contracted around his hand as if recognizing him, or trying to. A faint current crawled through his dead nerves—not electricity, not exactly. More like a biological system attempting to read him through touch. Then rejecting what it found. The sensation crawled up his arm and settled in his spine like a living memory he did not own.

Then came the sound of tearing meat. The cathedral opened. Not by sliding. Not by swinging. It split down the center as fibrous tissue peeled apart and revealed a tunnel of soft red flesh beyond. Moisture clung to the edges in long strands, trembling like saliva. From within came whispers. Too faint at first. Then clearer. Then unbearable.

"Amen…"

"Amen…"

"Amen…" Hot breath rolled out, thick with incense, burned fat, old prayer, and unstable Flux residue. John swallowed hard. The scientist in him wanted to stare longer. The survivor in him wanted to run.

"This is the main cathedral," he murmured.

"The central heart of the Silent Sanctuary." Z-69 looked at him.

"Heart." John's mechanical eye flickered, struggling to stabilize its scan.

"That's what we called it before we became stupid enough to make the name literal." They stepped inside. The world opened into horror. The cathedral stretched upward into darkness so vast it felt bottomless. The walls were not stone, but flesh—layer after layer of living tissue webbed with veins of red light. Every pulse in those veins matched the thunderous beat beneath their feet. Thump. Thump. Thump. Not symbolism. Not metaphor. A real heart. A real organ.

A real god-machine still alive centuries after the people who built it had died. Cables hung from the ceiling like exposed intestines, braided together with arteries carrying dark plasma through the body of the room. The floor was a translucent membrane, thin enough to show movement below—organs shifting, chambers contracting, veins feeding deeper into the structure. Faint letters flickered across broken displays half-buried in the walls.

[SANCTUARY BIO-FLUX HEART: ACTIVE] [CONDENSED FLUX RESERVOIR: CRITICAL INSTABILITY] [OMEGA-FAITH ARRAY: PARTIAL FUNCTION] [CORRUPTION BLEED: CONTAINMENT FAILED] At the center of it all floated a sphere nearly two meters wide. A crimson orb suspended by living threads. It trembled with every beat and bled faint flares of energy into the cathedral around it. Z-69 stared up at it.

"The heart of the Sanctuary…"

"And the core of Omega-Faith," John said. His mechanical eye flickered as it recorded the chamber, but his voice carried something more dangerous than fear. Memory.

"This is where they harvested faith itself as energy." Z-69's gaze moved from the orb to the bodies fused into the walls.

"Faith." John's mouth twisted.

"Faith, grief, obedience, pain, prayer—call it whatever makes the ethics committee vomit less. Prime Flux carries resonance. Human emotion gives it direction. Omega-Faith was supposed to stabilize mass panic during Corruption outbreaks." A dry laugh escaped him. This story originates from a different website. Ensure the author gets the support they deserve by reading it there.

"It worked. Then we got ambitious." The walls moved. At first, only shadows beneath the flesh. Then shapes. Then faces. Dozens. Hundreds. Bodies began pressing outward from the living walls—naked human forms half-fused into the tissue, skin pale and stretched, lips split, eyes glassy but awake. Their chests rose and fell in slow synchronized rhythm, like a choir forced to share one breath. Every exhale carried fragments of prayer.

"Help me…"

"Kill me…"

"You are our light…" Their voices layered over one another until the sound became almost beautiful. Almost. Lumina pressed tighter against Z-69's neck. Her blue glow dimmed. The souls… she whispered into both their minds. They're in pain… His hands curled into fists. Something stirred inside him—not hunger, but rage sharpened into something quieter. Older. Something that remembered, without memory, that people like these were supposed to be protected.

"Then we end it." The floor answered. A deep tremor rolled up through the membrane. The ground bulged. Split. Something below moved with enough weight to shake bone. Then came a roar. Not quite animal. Not quite mechanical. Something between a church bell and torn lungs. The crimson light deepened until the whole hall looked submerged in blood. From the center of the chapel, a colossal shape rose. The fleshy pipes feeding the heart snapped one by one, spraying arcs of molten red light across the room.

Then the display flickered overhead. [BIO-GUARD ALPHA – EXPERIMENTAL MUTANT ZC-01] [PRIMARY FUNCTION: PROTECT BIO-FLUX HEART] [SECONDARY FUNCTION: PRESERVE OMEGA-FAITH ARRAY] [CURRENT STATUS: CORRUPTED / DEVOTIONAL LOOP ACTIVE] The same monster from below. But not the same. Before, it had been a beast. Now it was a monument. It towered nearly ten meters high, a grotesque cathedral built from bodies. Human torsos twisted through its frame. Limbs fused into pillars of meat.

Faces were embedded across its mass in frozen expressions of ecstasy, agony, or both—as if the difference had stopped mattering a long time ago. Under its skin, thick red channels pulsed with condensed Prime Flux, moving like molten blood through artificial vessels. The energy should have been clean. Controlled. Filtered. Instead, it had been soaked in prayer until it learned to worship pain. Across its chest hung a cracked prayer-speaker unit. It sputtered alive.

"Save us. Save us. Save us." Then another line, layered over itself in static and broken reverence.

"Administrator John R… lead us to salvation…" John flinched. The title hit him like a blade. His jaw tightened.

"Damn it," he muttered.

"Not again." Z-69 stepped forward.

"Then we finish it." Lightning crawled across his skin. Purple light bled from the crystal in his chest. The displays around the cathedral spasmed. [THUNDERLIGHT SIGNATURE DETECTED] [PRIME FLUX COHERENCE DISRUPTED] [OMEGA-FAITH HEART RESPONSE: HOSTILE] Alpha moved first. Its first step was an explosion. Its second shattered a support column. The entire chapel convulsed as the monster charged, air pressure folding inward from the force of its movement.

Z-69 launched to meet it, body wrapped in crackling violet arcs, and drove his fist into the thing's side with enough force to buckle steel. The impact thundered through the cathedral. Flesh burst outward in chunks. Bone fragments flew. Bodies split apart. Then everything closed again. Regenerated. Reformed. Replaced. The Bio-Flux Heart pulsed above them, feeding Alpha through every living thread connected to the chamber.

Red energy poured into the monster's wounds, carrying stolen prayers and condensed Flux through corrupted tissue. Alpha did not heal like an animal. It restored itself like a system obeying a command. Alpha's counterattack came instantly. A cable-thick arm whipped sideways and struck with the force of a train. Z-69 crossed both arms to block. CRACK. Bone splintered. The blow hurled him across the hall and smashed him into the living wall hard enough to make the tissue behind him bulge outward.

He slid down, leaving a red streak that the wall greedily absorbed back into itself. John raised his plasma gun and fired in rapid bursts. Blue bolts tore into Alpha's ribs, carving smoking holes through its flesh. Acid blood sprayed outward in sizzling arcs. Wherever it landed, the floor screamed and boiled, then began knitting itself back together. One droplet struck his shoulder. His coat burned away instantly, revealing silver cybernetics beneath. He hissed through his teeth.

"Bio-acid blood. Flux-fed regeneration. Devotional resonance loop. Just fucking lovely." Lumina leapt from Z-69's shoulder and spread a blue psychic field through the air. For one second, Alpha's movement slowed. Only one. The monster's many mouths opened. They sang. Not in pain. In worship.

"Help me."

"Kill me."

"Amen." The hymn rolled through the cathedral and synced with the pulsing walls. Around them, the fused bodies began whispering harder, louder—like the whole chamber was trying to pray itself into a different reality. John's mechanical eye flashed warnings faster than his mind could process them. [RESONANCE PRESSURE RISING] [LOCAL PRIME FLUX FLOW: DIRECTED BY COLLECTIVE PRAYER] [OMEGA-FAITH ARRAY ATTEMPTING MASS SYNCHRONIZATION]"Of course," John whispered. Z-69 rose again. His ribs were already knitting.

The crystal in his chest pulsed violently, pouring energy into the repairs. Too much energy. The hunger noticed. It always noticed.

"Enough." He exploded forward, kicked off a ruptured pillar, and drove a spinning strike into Alpha's head. Half its face burst apart in a rain of blood and tissue. Then cables crawled through the gap. Bone regrew. A new face formed. Grinning. Wider than before. Alpha's massive hand came down, caught Z-69 mid-motion, and closed around him. Pressure crushed inward. His ribs groaned. His metal bones screamed.

The crystal in his chest shifted under the force and something cold passed through his organs—the first true warning that this body could, in fact, break. Alpha leaned in close. Its many mouths whispered in chorus.

"Administrator… pray with us…" Z-69 spat blood.

"John! Weak point!" John's mind raced. The plasma gun was useless now. This size, this density, this level of regeneration—there was only one answer.

"The center of its back!" he shouted.

"Under the energy core! But you'll need to pierce the alloy spine and shield!" Z-69 looked toward Alpha's back. He saw it then. Not with eyes alone. The violet crystal in his chest pulsed, and for a moment the monster's internal structure appeared in fragments of instinctive understanding. The red heart-thread feeding Alpha. The Flux spine beneath its flesh. The prayer-speaker acting as a resonance anchor. The false holiness keeping a corpse-machine alive. Alpha roared. Z-69 moved anyway.

He twisted inside the grip, broke two fingers free, and drove a burst of lightning into the creature's wrist. The hand spasmed. The grip loosened. He tore free, kicked off Alpha's arm, and launched toward its back. But Alpha was faster than something that size had any right to be. It caught his leg. And threw him. Z-69 shot upward like a missile and slammed directly into the suspended Omega-Faith core. The entire cathedral shook. The crimson orb cracked. A blinding burst of red light exploded outward.

He crashed back down through the air and hit the membrane floor hard enough to rupture it beneath him. For one heartbeat, he did not move. Then the crystal in his chest began to pulse. Once. Twice. Then violently.

"No…" Lumina's voice trembled.

"No, no, don't—" She sprinted toward him, blue light trailing behind her like torn ribbons. John lunged for the nearest control altar and jammed his hand into the emergency console.

"I need to shut it down," he hissed.

"That much condensed Flux will cook him alive—" The system activated on its own. A voice boomed through the cathedral.

"Synchronization detected."

"Heart resonance in progress." The ceiling split open. Rivers of red energy poured downward. Not into the core. Into Z-69. Straight into the crystal in his chest. John's face went pale.

"No." The red current was not just energy. It was Prime Flux saturated with three centuries of prayer, fear, worship, agony, and failed salvation. It carried the shape of a thousand dying minds, all trying to turn one body into an answer.

"Z-69!" John shouted.

"Damn it, get up!" But it was too late. The color of the energy began to change. Red bled into violet. The cathedral screamed. Lightning erupted around Z-69's body in writhing coils. His skin cracked open along the arms, neck, and chest. Flesh tore. Healed. Tore again. The smell of ozone and burned blood swallowed the cathedral whole. Displays across the walls shattered one by one.

[PRIME FLUX CHANNELS: OVERRIDDEN] [OMEGA-FAITH RESONANCE: REJECTED] [UNKNOWN VIOLET FIELD: EXPANDING] [CORRUPTION BLEED: BURNING] Alpha charged. Then stopped. The closer it came, the more it burned. Flesh blistered. Faces across its body began blackening, then curling into ash—as if the air around Z-69 had become too violent for anything else to survive inside it. Z-69 rose slowly. His eyes opened. They were no longer green. They blazed violet. Not rage. Not madness. Something colder. Something heavier.

The floor beneath his feet cracked as he took one step forward. Then another. Each movement sent arcs of lightning whipping across the chamber. Veins in the walls burst. The membrane floor blackened wherever he stood. John stared at him. Prime Flux flowed. Corruption spread. Faith resonated. Magic invoked. Technology commanded. But this— This refused. Thunderlight did not behave like ordinary energy. It did not merely absorb the red current. It judged it. Rejected it. Burned away the parts that did not belong.

Alpha screamed and slammed its fist down with everything it had left. Z-69 caught it with one hand. The impact shattered the ground around him into molten fragments. He did not move. Not one inch. The storm inside him surged outward. Lightning wrapped around Alpha's arm and spread over its whole body, drilling through flesh, burning through steel, melting cables into streams of slag. The prayer-speaker on its chest exploded in a shower of sparks. Its mouths howled.

"Administrator John R…!"

"You promised salvation!" The cathedral convulsed with it. Every red vein on the walls turned white-hot. Bodies fused into the flesh writhed and cried out—as if the entire structure had realized, too late, that its god was being replaced. Z-69 raised his free hand. Power gathered there. Compressed. Focused. Shaped into a sphere of violet-white destruction the size of a human heart. The Omega-Faith core above him cracked wider.

Condensed Prime Flux, old prayer, and corrupted biological energy spiraled toward his palm, only to be stripped apart by Thunderlight and remade into something cleaner. Crueler. Alpha staggered backward. Its countless embedded faces began fusing together into one colossal mask, smiling and pleading and terrified all at once.

"Sa… vior…" it whispered. Z-69 looked at it with expressionless eyes. He remembered nothing. Not his old name. Not his old life. Not the promises made for him. But he understood this much. If salvation had a shape in this place, it was not mercy. He lifted two fingers. Like a gun. The whole cathedral seemed to hold its breath. Then he spoke. Softly. Almost gently.

"Bang."
