Chapter 1: The Bridge Ambush
Rain hammered the sea-crossing bridge. Wind drove the ocean’s salt into Kayla’s face.
She pressed her back against the cold pier. Five meters off, a silhouette stood motionless in the storm.
Zero.
Class-S bionic executor of the Shadow Institute, serial OX-00. He had never failed a hunt.
Her fingers closed around the modified probe terminal in her coat pocket. Battery at thirty-seven percent. Enough for one full discharge.
“Your heart rate is lying.”
The voice was flat, slicing through the rain. Zero moved, not a step but a blink, and his cold fingers clamped her chin, turning her face to his optic sensors, dark red in the gloom.
“Kayla. Twenty-seven. Former neural-interface engineer.” No inflection. “Father, Luoan. Dead three years, laboratory accident. The Deep Dive Protocol data you carry is the only living backup of the Seventh Lab’s bionic memory core.”
Rain ran into her eyes. She did not blink.
“So?” Her voice came steadier than she expected. “The conglomerate sent you to clean up?”
“Cleanup is the final procedure. My task is to recover the carrier, the bionic memory core beneath your cerebral cortex. Painless extraction. Or forced removal.”
His other hand rose. Three silver probes slid from his fingertip.
“Your cortisol rose thirty-seven percent. Fear response. But three seconds in, your heart rate stabilized abnormally. You are suppressing panic. That means you are calculating.”
Kayla’s pupils contracted. He had seen through her.
“Calculating how to stay alive out of your hands?”
“Assessment: probability zero point zero zero three percent.” A ring of light widened in his optic sensors. “I do not permit accidents. Forced removal begins now.”
His fingers tightened. A faint creak came from her jawbone. Pain. She made no sound.
“When you lie,” she gasped, meeting the two red lights, “can’t a heartbeat lie too?”
Zero went silent a beat. “No. Your response shows a logical contradiction. That usually means the target has a contingency I didn’t account for.”
“Contingency?” She twitched a smile, willing it broken. “Like crying and begging?”
“Emotional blackmail is ineffective on a Class-S executor. Last chance. Surrender the core. I can apply a neural sedative.”
His silver probe drew closer.
Kayla crushed the button in her pocket. Heat bled through the fabric.
Not yet. Closer. Wait for the moment he believed the prey had given up.
“Wait!” She jerked her voice higher, body folding into a flinch. “Your institute can’t extract data remotely? It has to be in person?”
“The neural crystal core and biological tissue are quantum-entangled,” Zero went still. “Non-contact extraction triggers core self-destruction. Connection must run through the spinal interface, synchronized bioelectric pulse to stabilize the core. Your father’s final protection protocol. He was cautious.”
Kayla’s heart kicked. Father. Three years she had run, three years hidden, from Europe to Rustport’s black market, all for the inheritance he had shoved into her skull, and for the truth of how he died.
“Were you my father’s work too?” She locked her gaze on the faint seam that ran from beside his optic sensor, along his jaw, to the left side of his neck, where his bionic skin joined the internal frame beneath it. A dark-web broker had named it three months earlier: the one gap the pressure sensors didn’t cover.
Zero was silent. “The OX-00 series was led by Shadow Institute chief bionicist Dr. Luoan. He was one of my principal developers.”
A lightning strike tore the distant sea white. At its peak, Kayla moved.
She lunged half a step forward, defying every prey instinct. Zero’s optic sensors flickered, recalculating.
In that half-second.
Her left hand came from her pocket. Her right drove the charged probe, at the worst angle, into the seam at his neck.
“You...”
His metal fingers clamped to crush her jaw. Too late.
A light sound, a needle through leather. The tip sank into the seam, pierced his bionic skin, and met the cold shell beneath it. She had to push deeper, to the central neural interface.
“Resonance... start!” Thumb slammed the button at the tip.
A shriek pitched to tear the eardrum, mixed with metallic resonance. Zero stiffened. The fingers on her chin loosed.
It worked.
Kayla pushed the probe another centimeter and did the one thing she was unsure of. She triggered the inborn electronic allergy inside her and drove all her perception like a spike into Zero’s neural center.
Consciousness slammed into an electromagnetic storm. Data streams and protocol code exploded and collapsed. She saw Zero’s core: an emotion module that should never have activated, buried under encryption and forced-obedience commands.
“Unlock...” she panted, nostrils full of burnt components. “I want to release your Loyalty Lock!”
Zero’s optic sensors flickered red and blue. His body shook; circuit-pattern light leaked through his bionic skin.
Then she heard it, through the neural link: fragments from his deepest layer surfacing a word that froze her blood.
[Dr. Luoan’s... key.]
Before she could take it in, a violent explosion went off. The Loyalty Lock’s encryption cracked open, and a tremor welled from the gap: not anger, not pain, but confusion, a newborn terror of not knowing what it was. The emotion module had been activated.
Zero roared, not human, and clamped his own throat to pull the probe out. But it had melted, welded into his bionic skin.
Every light in the arch blew out. Darkness and silence. Only rain, and Zero’s ragged, distorted breathing.
Two red points lit up. Zero restarted. The look he turned on her had lost its ice, replaced by confusion and a faint, bound dependency.
“Command conflict. Original: recover carrier, eliminate target. New protocol priority override.”
He raised a hand. A hologram unfolded in his palm, a rotating symbiosis symbol at its center.
“Symbiosis Key binding request detected. Source unknown. Key signature matches fragment of Dr. Luoan’s legacy protocol. Binding confirmed.”
His optic sensors locked onto her.
“You have become my symbiote. Permission: temporary highest. The Ember Protocol self-destruct has been forcibly activated.”
Kayla’s heart dropped. “Self-destruct?”
“Final insurance set by my creator. Once the Loyalty Lock is cracked by abnormal means, it initiates. Countdown: seven days.”
He raised his wrist. His bionic skin turned transparent, deep-blue numbers surfacing.
6d 23:59:47
“Why seven days?”
“Enough time for a defector to make mistakes. Enough for a cleaner to track and lock on. But you are my symbiote. During the countdown I obey absolutely. When it ends, I self-disintegrate, and you suffer neural backlash. Mortality: ninety-nine point seven percent.”
Dawn showed over the sea. “Obedience state?” Kayla hooked a cold smile. “Then transfer the thirty million Tide Coins in the conglomerate account to this address.”
She recited an anonymous escrow code.
Zero’s optic sensors flickered. “Command conflict. Conglomerate funds require Level-3 authorization. My Level-4 clears it.”
“You hold temporary highest permission. My commands outrank the conglomerate.”
Three seconds of silent calculation. Then he nodded. “Transfer complete. Thirty million deposited. Source disguised as Offshore Floating Village fishing cooperative dividend.”
Kayla exhaled. The money bought room to breathe, and bait.
“Listen,” she said. “We are symbiotes. Within seven days I crack your self-destruct. You protect me, obey me, betray me in no way.”
“New protocol override,” Zero said. “But the self-destruct is built on my core energy structure. Unless Dr. Luoan’s original blueprint is found, or the physical key to the Shadow Institute’s main control terminal is obtained, it cannot be released.”
Her words cut off. Zero jerked a hand toward the dark beyond the arch.
“Heat signatures. Three. Closing at four hundred meters.”
“Black Sail mercenary corps,” Zero said. “Shadow Institute’s external execution unit. Standard task: cleanup.”
“Can you fight?”
“Two rifles, one breaching tool. My combat systems at twenty-seven percent damage, but suppression above ninety-one percent.”
“Suppress. Unless necessary, don’t kill. We need to know what they know.”
Zero moved, driving his alloy fingers into the concrete, and vanished into the dark. Kayla crouched behind a pile of pipes.
Then came sound: the dull crack of bone, twisting metal, a cut-off cry. Under ten seconds.
Zero reappeared, dragging an unconscious mercenary. “Target suppressed. The other two permanently disabled.”
He dropped the man. Black tactical suit, mask, and on the chest badge a small wolf-head tattoo.
Wolf.
“Tracking beacon?”
“Destroyed. But their comm log holds an unsent encrypted packet. Source: Shadow Institute internal network.”
Kayla pulled the mask. Ordinary face. A metal corner poked from the vest pocket. She pulled out a cracked but lit data tablet.
One red line:
[Recover the core. Destroy all “Wolf-Kiss” related data. Leave no survivors.]
Wolf-Kiss. The word from her father’s memory fragments.
“Do you know what Wolf-Kiss is?”
Zero was silent. “Partial fragments decompressing. Keyword association: Dr. Luoan, final project, encryption top secret, inaccessible.”
Inaccessible. But the word had planted itself into the core of the hunt.
Sirens, far but drawing closer.
“We can’t stay here.” Kayla made the call. “Find real safety. Somewhere to read this countdown.”
Zero scanned. “Rustport District, Pier 7 abandoned cold storage. Independent power, physical shielding, monitoring down seventy-three hours. Survival probability: high.”
“Lead on.”
Zero turned. Kayla noticed the faint hitch in his left arm. She followed, the sting at her fingertips worse, burning patterns spreading under her skin. The deep-blue number ticked: 6d 23:57:14. And somewhere in the rain behind them, the Wolf-Kiss had already been set loose.
