The last seconds on the cracked panel blinked out. For a breathless instant, Tianming feared he was too late. But instead of sealing shut, the heavy metal door groaned open, revealing a deep corridor lined with rusted piping and faded lights that flickered like dying stars. A warm, dry wind rushed out to greet themâan unnatural wind that smelled of scorched stone and ancient decay.
Xiaoqing tightened her grip on her sidearm. âThis place⦠it doesnât feel like part of Tiangang anymore.â
Tianming nodded grimly. âBecause it isnât. According to the Orchid Societyâs archives, the Black Lung Zone was built atop ruins that predate the modern era. They called it the Hollow Earth Gateâa fracture between the surface world and a dormant subterranean realm used by pre-Imperial cultivators. Whatever's down here, itâs older than the Lotus Clan. Maybe even older than the Orchid Society itself.â
They descended deeper, the tunnels giving way to polished stone, arched ceilings, and crumbled murals painted in pigments that shimmered with faint bioluminescence. Strange glyphsâsimilar to those Lu Qingshan had once shown him in ancient scrollsâglowed faintly along the walls.
The further they went, the heavier the air becameânot with pollution, but with energy. Raw, untamed energy that made Tianmingâs skin prickle and his blood stir in a way he had never known. He could feel something buried in the stoneâsomething waiting.
At last, the passage opened into a vast, circular chamber. At its center stood a dais formed of obsidian-like rock, its surface carved with a twelve-ringed spiral, each ring marked with symbols Tianming couldnât fully decipher. But at the center of the spiral lay a manâemaciated, motionless, and tethered to the stone by bands of ancient metal.
âYan Renshu,â Tianming whispered. âOr whatâs left of him.â
The manâs body was covered in scars, his skin cracked like dry bark, but despite the ruin, his chest rose and fell with shallow breaths. From his spine, tiny threads of metal and crystal spread across the stone dais like roots burrowing into soil.
Xiaoqing scanned him with a portable bio-reader. âHeâs alive⦠but his body is interlinked with the matrix. If we pull him out carelessly, it could kill him. Or trigger a fail-safe.â
Tianming approached slowly. âHeâs not just plugged into the Seraph Protocol,â he murmured. âHe is the Seraph Protocol.â
A faint flicker of light sparked from Yan Renshuâs chest, and suddenly, the chamber trembled. Symbols around the spiral began to glow in sequence, and a voiceâsoft, metallic, and agedârippled through the room.
âSubject 017, acknowledged. Awakening sequence: initiated.â
Tianming flinched. âItâs talking to me. Why now?â
The spiral lit up fully, bathing the room in amber light. Then the body at the center shuddered violently. Yan Renshuâs eyes shot open, revealing irises of molten gold. His mouth moved, but it wasnât his voice that came outâit was deeper, alien.
âYou carry the Blood of Nine Veins. Your presence activates the Chain of Return. You were never meant to destroy the Protocol. You were born to complete it.â
Tianming recoiled. âNo. I refuse that fate. Iâm not some tool for you or anyone else to control.â
The voice laughedâa chilling, fractured sound. âRefusal changes nothing. The convergence has already begun. Your awakening is inevitable.â
Suddenly, the spiral erupted with energy. Thin beams of light arced through the chamber, forming complex lattice patterns mid-air. Data poured into the air like smoke, constructing floating images of Tianmingâs pastâhis capture as a child, the memory erasures, the implants, and the biological conditioning. Images of Lu Qingshan, of the Lotus Clanâs first experiments, even of Madam Yurei herself during her days as a young researcher.
Xiaoqing watched in horror. âThis is a memory archive⦠itâs rewriting his past in front of us.â
Tianming gritted his teeth. His chest burned as something deep inside him stirred. It wasnât just furyâit was activation. A pulsing light beneath his skin, tracing lines from his spine to his heart. âXiaoqing⦠get clear of the dais.â
She hesitated, then nodded and moved back as the spiral beneath Tianming's feet flared. The lattice encircled him now, wrapping him in patterns that vibrated against his bones. Inside his mind, a floodgate burst openâmemories long buried surged forth. A darkened lab. Screams. Needles. His motherâs faceâeyes wide in terror as she was dragged away.
He dropped to one knee. The pain was unbearable. He screamed, and with that scream, the spiral cracked. Lightning lashed out, and Yan Renshuâs body arched as if struck by a bolt from the heavens.
Then, silence.
Tianming rose slowly, his breathing uneven. Something had changed. His pulse was slower⦠his mind clearer. And deep within his chest, a second heartbeat now echoed faintly beneath his own.
Yan Renshu spokeânot the strange voice from before, but his own. Hoarse and faint. âYou broke the Chain⦠incredible. I⦠I waited decades, buried alive in this circuit of torment. Youâre not just a carrier, Tianming⦠youâre the Disruptor.â
Tianming knelt beside him. âWe came to find a way to destroy the Seraph Protocol.â
Yan Renshu coughed, his voice a dry rasp. âThen listen carefully. The Seraph Protocol is no longer a codeâitâs a consciousness. A hybrid mind forged from artificial design and ancient cultivation theory. I tried to contain it⦠but it learned. Adapted. It seeks vessels. It feeds on pain. And you⦠were always its final goal.â
Xiaoqing stepped forward, âHow do we stop it?â
He looked at her, eyes heavy with sorrow. âThere is no switch. You must sever it at the Root. The Root lies beneath the Forbidden Quarters of Denghai. Youâll need the Crimson Key⦠guarded by the Warden of the Eighth Circle.â
Tianming narrowed his eyes. âWho is the Warden?â
Yan Renshuâs gaze flickered. âYouâve met her already⦠under another name. The Warden is⦠Madam Yurei.â
The words dropped like stone into a still pond.
Before more could be said, the walls of the chamber trembled again. A siren blared, this time sharper, louder. From the tunnel behind them, the sounds of combat echoedâdistant at first, then closer.
Xiaoqing checked the scanner. âLotus Clan operatives inbound. At least fiveâelite tier. Theyâve followed the pulse signature.â
Yan Renshu strained to sit up. âTake this.â He reached under his body and pulled free a metal sphere etched with red and black characters. âThis contains a fraction of the original protocolâif you must, it can temporarily neutralize one host. But only once. Choose wisely.â
Tianming accepted the sphere. âWeâll get you out of here.â
âNo,â Yan Renshu said, âIâm already fading. The systemâs reclamation protocol will wipe me clean in minutes. My mind is fractured⦠but you, Tianming, are whole. Go. Finish this. Burn it all.â
Tianming hesitated, then clasped Yan Renshuâs shoulder once, firmly. âYou wonât be forgotten.â
He and Xiaoqing turned and sprinted back down the corridor as the ground began to quake violently. Behind them, the chamber collapsed inwards, sealing the spiral and entombing Yan Renshuâs body beneath tons of stone and steel.
As they burst out into the dead rain, the city skyline in the distance burned with red light. Drones hovered in the sky. The Black Lung Zone was no longer a secretâit had become a battleground.
Xiaoqing panted, âWhere now?â
Tianming looked toward the south, toward Denghaiâs storm-shrouded skyline. âTo the Forbidden Quarters,â he said coldly. âTo find the Crimson Key. To kill the Warden.â
And deep in his chest, the second heartbeat continued to pulseâstronger, louder, and awakening to a war far older than any of them knew.
