Chapter 6

Kai Ren’s workshop reeked of scorched wiring and bitter coolant. The notification drone’s chime still drilled through his skull: thirty-nine hours until the open-broadcast prelim against Arlen Voss. Sixty-five hours until the ranking audit locked the ladder. One misstep and the academy would strip his frame for scrap and chain him to the same sixty-five thousand five hundred forty credits of unbreakable debt.

He stood inside the salvage frame’s open chest cavity, left arm buried to the elbow in the core housing. Retinal diagnostics burned across his vision: flux-reroute stable at eight-second full burst, Shadow Circuit Variant stretching the left-arm power window to fourteen point seven seconds, baseline heat already four percent above yesterday’s final test. Every upgrade carried its own visible meter. The permanent non-stock signature throbbed under the alloy like a second, hungry pulse.

Liora Vex’s voice cut across the forced-open channel she had hijacked. “Enjoy the spotlight, Ren. The whole academy’s watching. Try not to melt before the first exchange.”

Kai ignored her. He triggered another calibration cycle, watching the heat curve spike then flatten as the Shadow Circuit bled excess into the secondary capacitors. Measurable. Costly. Necessary.

Master Selen’s boots rang across the grated floor. The old pilot’s scarred face appeared in the polished conduit. “You’re still treating it like a machine. It’s learning your reflexes faster than you’re learning its moods.”

Kai pulled his arm free, fingers aching in sympathy. “It bought me nineteen percent efficiency in the plaza. That’s not theory. That’s board state.”

Selen slapped a fresh diagnostic wafer onto the core. Violet light from the embedded Void Codex fragment flared, then sank into the metal like ink remembering old veins. “The fragment isn’t just rerouting power. It’s rewriting contact protocols. One more combat stress cycle and the autonomy index crosses the academy’s red line. They’ll label it corruption. They’ll label you rogue.”

Kai met the older man’s eyes. “Then I make the win look clean enough they can’t afford to dig deeper.”

Selen’s laugh came short and dry. “Clean? You’re running banned flux-reroute, a forbidden variant, and a Void Codex shard that’s eating examiner marks. The only clean thing left is the debt contract.” His voice dropped. “And Liora just forced full open broadcast. Every sensor in the arena will be hunting anomalies. One stutter in your signature and the seizure drones are airborne before the echo dies.”

The frame’s core gave an involuntary thrum that vibrated up through the deck plates—more power, less margin. Kai sealed the chest panel with a decisive clang. “Thirty-nine hours. I need it ready, not safe.”

Selen studied him a beat longer, then gave a single nod. “Then stop pretending you can still climb clean.”

The arena prep zone smelled of ozone and hot hydraulics. Cranes locked the salvage frame into the staging cradle while broadcast drones circled like metallic wasps. Kai climbed the gantry, rank still frozen at 47/50 on every public board. Arlen Voss—rank 29—waited opposite in a glossy academy-issue frame, plasma whip already coiled and glowing.

Liora stood at the broadcast edge, arms folded, academy crest gleaming. She didn’t speak. The tilt of her chin said everything: every heat spike, every non-stock pulse would be dissected live for the sect market and the ladder alike.

Kai locked into the cockpit. Harness clicked. Diagnostics painted across his visor: left-arm window holding at 14.7 seconds, flux-reroute primed, core temperature already three degrees above idle from the short walk-over. Visible. Earned. Expensive.

The arena horn blared. Crowd roar crashed over the open channel like breaking steel.

Arlen struck first—textbook fast—plasma whip cracking across the gap. Kai’s frame sidestepped, servos screaming. The whip carved a shallow gouge across the left shoulder plate. Heat spiked. Shadow Circuit bled it sideways, buying four extra seconds before the warning tone.

Kai answered with a controlled flux-reroute burst. Left arm snapped up. Eight-second window burned white. The shot sheared Arlen’s whip mid-coil. Sparks exploded. The crowd surged.

The bleed hit harder than any simulation. Secondary capacitors glowed cherry-red. The frame’s core lurched; autonomy index flickered upward as the Void Codex fragment pulsed, tasting the fight.

Arlen closed, switching to kinetic blades. Metal rang. Kai locked the longer Shadow Circuit window and drove a brutal overhead that forced Arlen back two full steps. Fourteen point seven seconds of raw power—measurable, glorious, terrifying.

Then the heat curve shattered.

Klaxons screamed. Core housing temperature redlined. The stabilization module whined under overload. One more second and the left arm would fuse into slag, dragging the shoulder assembly with it. Arlen spotted the stagger and lunged, blades angled for the exposed joint.

Kai’s survival instinct took the helm. He married the banned flux-reroute to the very edge of the Shadow Circuit bleed in a sequence no academy manual would ever sanction—eight seconds of full power fused to the forbidden extension. The left arm became a white-hot piston. He slammed it into Arlen’s guard, driving the mid-tier frame sideways into the arena barrier with a bone-rattling crash.

Metal screamed. The crowd lost its mind.

Inside the cockpit the world narrowed to flashing red. The frame bucked hard, autonomy index spiking as the Void Codex fragment surged, rewriting emergency protocols on the fly. For one heartbeat Kai felt the machine trying to choose for him—keep fighting, keep burning, keep climbing.

He killed every non-essential system, dumped coolant straight into the core, and rode the dying heat curve down. The salvage frame dropped to one knee, left arm smoking, but still functional. Arlen’s frame stayed pinned against the barrier, systems flickering, pilot visibly shaken.

The referee horn sounded. Technical victory. No expulsion. No immediate seizure.

Kai’s rank ticked to 46/50 on the public boards—visible, public, earned at the cost of smoking components and a frame that now felt a fraction less his own. The debt remained locked at sixty-five thousand five hundred forty credits, but the ladder had widened by one painful rung.

Before the broadcast drones could swarm for close-ups, a priority alert flashed across his feed. The sect market dealer’s seal. Interest-rate adjustment effective immediately. Penalty clauses tightening. A private channel request blinked blood-red: “New terms. Bring the frame. Tonight.”

Kai tasted copper and ozone. The frame’s core gave one final, hungry thrum beneath his hands, almost as if it were already listening for the next order.

Outside the barrier, Liora Vex watched the boards with narrowed eyes, her earlier smirk wiped clean.

The climb had just become far more expensive.
