Chapter 1 – The Purge Protocol

The klaxon does not merely ring; it vibrates upward through the titanium floorboards of the Sanguis-Geum apex laboratory, rattling the marrow inside my bones. Red strobe lights wash over the pristine white surfaces of my workstation, turning the sterile, high-altitude room into a slaughterhouse before a single drop of blood has even been spilled.

I stare at the massive panoramic monitors dominating the 102nd floor. Lines of executing code—my code, twisted and hijacked—scroll down the glass screens like digital blood weeping from an open wound.

Command Network: Online. Calibration: 10%. Target Protocol: Absolute.

Han Tae-jin did it. The Director actually pushed the button.

My breath catches in my throat, a hard, sharp gasp that tastes of ozone and recycled air. For three years, I designed Chroma. I engineered the synthetic blood to be a miracle, a sustainable food source that could perfectly mimic human desire, memory, and emotion for the vampire elite of vertical Seoul. I mapped the hematological pathways. I built the architecture. I thought I was ending a shadow war. I thought I was saving human lives from the feeding alleys.

Instead, I built a leash.

Tae-jin had secretly embedded a sleeper protocol within the Chroma supply. Anyone who consumed it—which was now ninety percent of the city’s vampire population—had my synthetic pathways woven into their nervous system. And with the Command Network active, he could overwrite their free will. He could turn millions of thinking, feeling beings into a synchronized army of bio-drones.

"Override," I snap, my fingers flying across the haptic keyboard. "Authorization: Min Seo-yeon. Terminate Protocol Absolute."

Access Denied. Terminal Locked.

"Damn it," I hiss, slamming my fist against the console.

The heavy, reinforced blast doors of the laboratory slide shut with a pneumatic hiss, the magnetic locks engaging with a heavy, final thud. I am trapped. The threat matrix on my secondary screen flashes crimson, showing a complete lockdown of the upper executive tiers. Tae-jin isn’t just seizing control of the Network. He is erasing the evidence. He is erasing the architect.

I spin away from the console, my mind racing through the calculus of survival. The primary elevator is dead. The service shafts are sealed. The only way out of a corporate fortress suspended thousands of feet above the neon slums is to fly, or to fight.

I am a scientist, not a soldier, but I know the anatomy of a monster perfectly.

I reach under my desk and pull out my modified surgical scalpel. The hilt is wrapped in grip-tape, the monomolecular edge humming with a faint, lethal vibration as I activate the power cell. It is meant to slice through bio-synthetic armor plating, but it will work just as well on flesh.

The temperature in the room plummets. A localized pressure drop.

Above me, the reinforced glass ceiling of the apex lab groans.

I drop through the ventilation shaft like a guillotine blade, the eighty-story freefall nothing but a rush of freezing air against my tactical suit.

My objective is simple. It is always simple when Han Tae-jin issues a royal writ of execution. Infiltrate the apex lab. Execute the architect, Dr. Min Seo-yeon. Burn the blueprints.

I am Han Mirae. I am the Director’s chief executioner, the heiress to a bloodline built on absolute authority and ruthless precision. I do not question the orders. I do not feel the weight of the lives I extinguish. I am a weapon, perfectly calibrated and perpetually cold.

At least, that is what the Chroma I am forced to drink tells me to be.

The artificial blood still sings in my veins from my pre-mission ration, an intoxicating cocktail of synthetic adrenaline and engineered loyalty. It makes me fast. It makes me lethal. But beneath the programmed rush, in the silent, suffocating depths of my own mind, I feel the agonizing chafe of the collar around my neck. I despise the synthetic taste. I despise the way it mutes my true instincts, wrapping my ancestral power in corporate code.

I hit the access grate above the laboratory. I do not bother overriding the electronic locks. I channel my momentum, driving my combat boots downward.

The reinforced glass shatters inward.

A cascade of diamond-sharp shards rains down into the laboratory, reflecting the crimson emergency strobes. I detach myself from the falling debris, landing on the titanium floor with a heavy, flawless crouch. The kinetic shockwave ripples outward, shattering a row of glass hematology centrifuges.

I rise, drawing my twin combat blades. The room smells of ozone, sterile chemicals, and the rapid, terrified heartbeat of a human.

She is standing on the far side of the console. Dr. Min Seo-yeon.

She does not look like the architect of a global control network. She looks fragile. Her dark hair is pulled back in a messy knot, and she is wearing a standard white lab coat over dark slacks. But as my predatory gaze locks onto her, I register the weapon in her hand—a vibrating surgical dagger—and the absolute, icy calculation in her dark eyes.

She isn’t cowering. She is analyzing me. Finding my weak points.

"You’re early," she says, her voice remarkably steady over the wail of the klaxons. "Tae-jin usually waits at least an hour before sending his hounds to clean up his messes."

"I am not a hound," I reply, my voice a soft, lethal purr that carries across the room. "I am the executioner. Put down the blade, Doctor. I promise I will make it quick."

"I don’t do well with promises," she fires back.

I lunge.

She moves faster than the human eye can track.

One second, the vampire is standing twenty feet away, a terrifying vision of aristocratic lethal grace in a midnight-black tactical suit. The next, she is right in front of me, the air displacement hitting my face a fraction of a second before her blade does.

I drop to my knees, throwing myself into a roll across the polished floor. Mirae’s blade cleaves the air where my neck was, slicing through the holographic display terminal and showering us in digital sparks.

I scramble to my feet, using a steel lab table as a barrier. My heart is threatening to hammer its way out of my ribs, but my mind is crystal clear. The threat is in the room. Survival requires action.

Mirae vaults the table with effortless, predatory fluidness. I thrust my scalpel upward, aiming for the gap in her armor under her arm.

She catches my wrist.

Her grip is like a steel vice, bruising the bone instantly. I gasp, looking up into her face. We are inches apart. Her eyes are a striking, unnatural shade of violet, glowing in the dim red light. Her skin is flawless, pale like polished marble, radiating a deep, unnatural cold. I can smell her—a scent of winter rain, copper, and the distinct, sterile undertone of my own Chroma formula.

She is terrifyingly beautiful. And she is going to kill me.

"You are outmatched, human," Mirae whispers, her gaze dropping to my lips for a fraction of a second before locking back onto my eyes. The proximity is suffocating. The sheer, overwhelming physical gravity of her presence makes the hair on my arms stand up.

"I know," I grit out.

Instead of pulling away, I step into her, driving my knee upward into her abdomen.

She grunts, her grip loosening just enough for me to twist my wrist free. I slash horizontally. The humming monomolecular edge of my scalpel catches her cheek, drawing a thin line of impossibly red blood.

Mirae recoils, touching the cut. She looks at the blood on her fingertips, a flicker of genuine shock cracking her stoic facade. Then, the shock is replaced by a predatory, blinding rage.

She lunges again, and this time, there is no evasion. She slams me backward into the reinforced glass wall of a containment cell. The impact knocks the wind out of my lungs, leaving me gasping for air. Her forearm presses against my collarbone, pinning me in place. She raises her blade, the steel poised directly over my heart.

"You shouldn’t have done that," she breathes, her fangs descending, grazing her lower lip.

I stare up at her, my lungs burning, refusing to close my eyes. If I am going to die, I will watch it happen.

But the strike never comes.

My blade is inches from the architect’s chest. Her pulse is hammering against my forearm, a frantic, desperate rhythm that is intoxicating in its raw vitality. Her dark eyes are wide, furious, and entirely defiant.

I tighten my grip, ready to end it.

Then, the world tears in half.

Command Network: Calibration 30%. Executing Override.

The voice does not come from the lab’s speakers. It comes from inside my own skull. It is a digital, cold frequency, carrying the unmistakable psychic weight of Han Tae-jin’s will.

A spike of absolute, blinding agony drives itself through my temples. It feels as if molten lead has been injected directly into my spinal cord. My muscles seize up. The combat blade drops from my trembling fingers, clattering uselessly against the titanium floor.

I stumble backward, releasing Seo-yeon, my hands flying to my head.

"No," I choke out, falling to my knees. "No, get out—"

The Chroma in my veins—the synthetic blood I drank, the formula she created—is turning against me. I can feel the code rewriting my neural pathways in real-time. It is erasing my thoughts. It is tearing away my disgust, my anger, my honor, replacing it with a blank, suffocating euphoria. It is turning me into a puppet.

Target acquired, the voice in my head echoes. Protocol Absolute. Destroy the architect.

My body begins to move without my consent. My right hand twitches, reaching for the fallen blade on the floor. My fingers curl around the hilt, my arm lifting the weapon, even as my mind screams in absolute terror. I am a prisoner inside my own flesh.

I force my head up, looking at Seo-yeon. My vision is blurring with tears of pure, humiliated agony. I am fighting my own biology, pouring every ounce of my formidable willpower into stopping my arm from driving the blade into her throat.

"Run," I manage to snarl, blood dripping from my lips as I bite my own tongue to fight the compulsion. "Run, you idiot!"

I press myself flat against the glass, watching the lethal executioner collapse.

Mirae is on her knees, convulsing, her violet eyes flashing wildly between total vacancy and sheer, panicked lucidity. She is fighting the Network. I can see the exact moment the code tries to force her to stand, the way her muscles lock and tremble in defiance.

Command Network: Calibration 40%.

The monitors above us blare the warning. The sleeper protocol is accelerating.

I look at the surgical dagger in my hand. Mirae is completely vulnerable. I could step forward right now, sever her carotid artery, and end the immediate threat to my life. It would be the logical, calculated choice.

But as I watch her tear her own mind apart rather than submit to Tae-jin’s control, a bitter, cynical realization hits me. We are both victims of the same man. I built the cage, but she is the one currently being locked inside it.

And if she dies, I am alone. I won’t survive the descent to the slums by myself.

A new alarm cuts through the klaxons.

WARNING: Perimeter breach detected. Executive Hounds deployed. ETA: 3 minutes.

Tae-jin is sending the clean-up crew. Heavily armed, fully networked, mindless bio-drones who won’t hesitate to slaughter us both.

I make a choice. It defies all logic, but it is the only variable on the board that might keep me breathing.

My raw, unaltered human blood—the Null Blood. It carries the original genetic blueprint, a biological anomaly that acts as a complete system crash to the Chroma network. I haven’t tested it in a live subject. But theory is going to have to be enough.

"I’m not running," I say.

I step forward, dropping to my knees right in front of the convulsing vampire. Mirae snarls at me, a feral, terrifying sound, her blade inching toward my chest against her will.

I raise my left hand. Without hesitating, I drag the monomolecular edge of my scalpel straight across my own palm.

The cut is deep. Red, hot blood instantly wells up, spilling over my skin. The scent of it hits the air—raw, metallic, and entirely human.

Mirae freezes. Her nostrils flare, her pupils dilating until her eyes are almost entirely black. The sheer hunger in her expression is predatory and deeply sexual, a raw, unmasked desire that sends a heavy shudder down my spine.

"Listen to me," I say, my voice hard, grabbing her jaw with my uninjured hand to force her to look at me. Her skin is freezing. "Tae-jin is hacking your nervous system. The Chroma is his backdoor. My blood is the only thing that can crash the signal and sever the link."

Mirae is shaking violently, her fangs fully extended. "It… will kill me…" she gasps out, fighting the urge to tear my throat out.

"No, it will bind us. A circulatory tether. It will flood your system with my antibodies, but it requires a constant loop to keep the Network out. You feed on me. I anchor you." I press my bleeding palm closer to her mouth. "Drink, Han Mirae. Choose to drink, or become his puppet forever."

I am giving her the choice. Absolute, explicit consent.

Mirae stares at my bleeding hand. The conflict in her eyes is agonizing—the pride of an executioner warring against the terror of enslavement.

Then, with a desperate, guttural sound, she surges forward.

She grabs my wrist with both hands, her grip bruising, and presses her mouth to my palm. Her lips are ice-cold, but her tongue is hot, a shocking, intimate friction against my torn skin as her fangs pierce the flesh.

The moment she drinks, the Blood-Bind activates.

It hits us both like a physical shockwave.

I gasp, my back arching violently as an electric current of sheer sensory overload rips through my veins. It isn’t just pain. It is an overwhelming, blinding rush of sensation. Suddenly, I can feel her. I can feel the ice in her veins, the frantic, terrifying speed of her reflexes, the crushing weight of her ancestral duty.

And she can feel me. I feel her shock as she registers my racing, fragile human heartbeat, my cynical intellect, my raw terror. Our consciousnesses slam into each other, bleeding across the connection.

The heat is instant and suffocating. The friction of her mouth on my hand sends a jolt of heavy, undeniable pleasure straight to my core, confusing my adrenaline-soaked brain. My breath hitches, my free hand involuntarily tangling in her dark hair to hold her closer.

Mirae groans against my skin, drinking deeper, anchoring her mind to mine. The violent trembling in her limbs stops. The glassy, programmed vacancy in her eyes shatters, replaced by fierce, unadulterated clarity.

She pulls back slightly, her lips stained with my blood. She is breathing hard, her chest heaving against mine, our bodies flush together on the floor of the ruined lab. The connection is a live wire humming between us—I can literally feel the phantom echo of my own blood racing down her throat.

"You’re completely insane," she whispers, her voice rough, her eyes locked onto mine with a new, terrifying intensity.

"Did it work?" I demand, my pulse hammering a frantic rhythm that I now feel echoing in her chest.

Before she can answer, the heavy magnetic locks on the laboratory doors blow inward in a shower of sparks and smoke.

Protocol Absolute: Engage.

Through the clearing smoke, a dozen figures step into the apex lab. They are clad in heavy corporate tactical gear, their faces hidden behind matte-black visors. But it is their movements that are terrifying—perfectly synchronized, eerily silent, lacking any human hesitation.

The Royal Hounds.

The purge protocol has reached our floor. The city is locking down. And the execution squad has found us.

Mirae rises, pulling me up with her in one fluid motion. Her grip on my wrist is no longer a threat; it is an anchor.

"Run now," she says, raising her blades toward the encroaching darkness.
