The big ones started arriving at hour twenty-three.
Not the fist-sized bottom-feeders that the Bureau's sidearms dispatched with single rounds. Not the softball-sized mid-tiers whose chitin plates required the mana-charged ammunition's penetrating capability. These were D-rank upper-tier specimens — bodies the size of dinner plates, legs spanning three-quarters of a meter, chitin armor thickened to the density that the species' growth stages produced in specimens whose age and mana accumulation placed them at the top of the rank's classification. The upper-tiers moved differently than the smaller specimens. Slower. More deliberate. The movement of creatures whose size provided the physical confidence that the smaller specimens' speed-based survival strategy replaced.
The first upper-tier came through the north corridor. Operative Kwan — sidearm, second magazine, eight rounds remaining — engaged at twelve meters. The first round hit the thorax's chitin plate. Didn't penetrate. The mana-charged ammunition's kinetic energy absorbed by the armor's density rather than transmitted through the armor to the biological mass beneath. Kwan fired again. Same target zone. The second round cracked the plate's surface without breaching the interior. Third round — the crack's weakened zone providing the entry point that the third round's kinetic energy exploited. Penetration. The spider staggered. Fourth round into the breach. Kill.
Four rounds for one spider. The upper-tiers' armor requiring the ammunition investment that the lower specimens' thinner chitin hadn't demanded. Four rounds from an eight-round remaining magazine. Kwan's sidearm now had four rounds. The next upper-tier would cost half of them or all of them depending on whether the first round found an armor gap or hit solid plate.
The counter registered the kill. The upper-tier's death within the fifteen-meter perimeter — within the amplification field's peak intensity zone — producing the enhanced attribution that the construct's proximity effect provided. The contribution was larger than the lower specimens' kills. The upper-tier's greater mana content generating the experiential value that the system's attribution framework scaled with the creature's biological mass and mana integration level.
9,823.
A jump. The upper-tier's single kill adding more than the lower specimens' deaths had contributed individually. The counter's progression rate increasing not just from the kill frequency but from the kill quality — the higher-value targets' enhanced contributions accelerating the counter's approach toward the threshold.
More upper-tiers followed. The construct's strengthening gradient pulling the larger specimens from the deeper population reserves that the lower-ranked bottom-feeders and mid-tiers had been drawn from first. The ecological order: the small ones came first because the small ones were more numerous and more responsive to the gradient's pull. The big ones came later because the big ones were fewer and the gradient's pull needed to strengthen before the pull exceeded the big ones' territorial inertia. The gradient had strengthened. The big ones were moving.
The Bureau operatives adapted. The sidearm-equipped personnel targeting the upper-tiers with the concentrated fire that the armor demanded — two operatives engaging the same target, the combined fire's ammunition cost split between the operatives' magazines. The knife-equipped operatives handling the lower specimens that the sidearm fire's noise and the upper-tiers' presence hadn't deterred from their own approach.
The perimeter held. Barely. The kills coming fast and expensive. The ammunition consumption's rate tripled by the upper-tiers' armor requirements. The magazines' remaining capacity draining toward the zero that the engagement mathematics' trajectory projected.
9,841. 9,857.
The counter climbing. The construct's amplification field converting the defensive combat into the experiential accumulation that the system's framework attributed to Shin's shadow experience. The kills that the Bureau's operatives produced — the deaths that the institutional defense generated, the combat whose purpose was the containment protocol's perimeter maintenance — feeding Shin's progression toward the threshold that the system had placed at 10,000.
The irony was structural. The Bureau's containment protocol existed to manage the anomaly. The protocol's perimeter defense killed spiders. The spider kills fed the anomaly's bonded subject's experience accumulation. The containment was accelerating the very progression that the containment's management function was designed to control.

Operative Park went down at 9,863.
An upper-tier came through the western passage — the corridor whose mouth opened into the fifteen-meter radius at the angle that the defensive circle's coverage model's geometry placed in the gap between Park's position and the adjacent operative's arc. The spider's approach from the gap angle meant neither operative had a clean engagement line. Park repositioned. The fractional second of movement — the weight shift, the sidearm's reorientation — placed the operative's left arm in the spider's strike range as the spider lunged.
The bite was fast. The upper-tier's chelicerae — the mouthparts whose mana-enhanced chitin served as the species' primary offensive mechanism — closing on Park's left forearm with the compressive force that the D-rank upper-tier's muscle mass produced. The compression garment's material resisted for a fraction of a second before the chelicerae's edges penetrated the fabric and the skin beneath and the muscle beneath the skin.
Park fired. Point-blank. The sidearm's muzzle against the spider's thorax. The round entered the chitin at contact distance — the penetration that the armor's density denied at range achieved through the contact range's elimination of the kinetic energy's dispersal over distance. The spider died with its chelicerae still embedded in Park's forearm. The dead spider's grip releasing as the nervous system's motor control ceased.
Blood. The forearm's wound bleeding with the steady flow that the vascular damage's severity — the chelicerae's penetration reaching the forearm's superficial arteries — produced. Park dropped to one knee. The sidearm held in the right hand. The left arm's blood darkening the crystal floor's surface in the spreading pattern that gravity and the wound's flow rate determined.
"Medic." The adjacent operative's call. The battlefield request whose single word communicated the urgency that the single word's standardized meaning carried.
Mira was on her feet. The healer's response to the combat injury's call — the professional's trained reaction bypassing the decision-making that deliberation required. The response was automatic. The body moving before the mind completed the assessment that the body's training had already conducted through the audio input that the injury call provided. Someone was bleeding. The healer moved.
But Shin was her patient. The integration site's boundary advancing toward the carotid sheath at one centimeter per hour. The secondary bond point in the neck conducting at sixty-eight percent. The calcium supplementation's eight remaining tablets maintaining the mineral economy that the integration's consumption depleted. Mira's continuous monitoring was the clinical management that the patient's unprecedented condition required — the reader's data, the thermal measurements, the boundary tracking that the healer's methodology provided for the condition whose progression the methodology's documentation was the only basis for the clinical decisions that the condition's evolution demanded.
She looked at Shin. At Park. At the blood on the crystal floor ten meters away. The healer's clinical calculus running the assessment whose variables included the two patients' relative acuity — the immediate life threat of the arterial bleed versus the gradual existential threat of the integration's advance — and the healer's capacity to serve both when the two patients occupied positions separated by the distance that the three-meter tether and the ten-meter perimeter placed between them.
"Go." Shin said.
She went.
The medical kit on her hip. The reader in the interior pocket. The healer crossing the habitable zone's four-meter boundary into the transition zone's higher-density atmosphere — the compression garment's protection adequate for the brief exposure that the ten-meter transit required. Mira reached Park in six seconds. Knelt in the blood. Hands on the wound. The field treatment's protocols activating through the trained motor sequence that the arterial bleed's management demanded.
Shin watched from the construct's base. Thirteen meters from the treatment site. The healer's back to him. The reader in the kit on the healer's hip — the clinical instrument's data unavailable to the patient whose monitoring the instrument served. The patient alone with the construct for the first time since the bond's formation.
Not alone. The contractor at six meters. The division's instruments scanning. The Bureau's operatives fighting at the perimeter. The spiders dying. The counter climbing.
9,874. 9,881. 9,889.
The upper-tiers kept coming. The defensive circle's integrity compromised by Park's removal from the formation — the wounded operative's position now covered by the adjacent operatives' extended arcs, the coverage's overlap reduced, the gaps widened. The kills continued. The ammunition continued to deplete. The construct's gradient continued to pull. The loop continued to feed.
9,903.
The number's third digit rolling over. Nine thousand nine hundred. Less than a hundred points from the threshold. The kills' frequency and the upper-tiers' enhanced attribution combining to drive the counter's rate past the projections that the earlier arithmetic had produced. Not thirty minutes. Not forty-five. The crossing was close. Minutes. The counter's acceleration compressing the timeline that the accumulation's trajectory determined.
9,917. 9,924.
Mira was applying the field dressing. Park's arterial bleed controlled — the healer's compression and the hemostatic agent's clotting action combining to reduce the flow from the steady stream to the managed seep that the field treatment's objective specified. Park would need evacuation. The wound required the surgical intervention that the field treatment couldn't provide. But the immediate crisis — the blood loss, the arterial output — was managed.
Mira turned. Looked at Shin. Thirteen meters. The healer's clinical awareness registering the patient's status from the distance that the patient's tether and the treatment site's location imposed — the visual assessment that the clinical training provided for scenarios where the instruments' proximity wasn't available.
She started back.
9,938.
The construct's pulse changed. Not the frequency — still sixty-one. The character. The quality of the rhythm shifting in the way that Shin's awareness of the bond's dual-pathway transmission detected but that the external observation's instruments would register only as a slight modulation in the output's waveform. The construct was doing something. Preparing for something. The crystal architecture's processing cycle allocating resources to a function that the standard atmospheric conversion and the thermal output and the amplification field's maintenance didn't include.
9,951.
Shin's skin prickled. The integration site's modified tissue and the secondary bond point in the neck both responding to the construct's preparatory shift — the hybrid tissue's sensitivity to the crystal's operational state detecting the change that the bond's continuous connection transmitted. The prickling wasn't pain. Wasn't the integration's thermal output. Was something else — a vibration beneath the skin's surface, a resonance in the modified fascia that the construct's preparatory function was generating through the bond's conduction pathway.
9,967.
Mira was at seven meters. Walking fast but not running — the transition zone's atmosphere requiring the measured breathing that the compression garment's respiratory management supported, the pace limited by the atmospheric density that the habitable zone's boundary placed between the treatment site and the patient. Seven meters from Shin. Three meters outside the habitable zone. The healer moving through hostile air toward the patient whose monitoring she'd left to treat a bleeding operative.
9,978.
The vibration intensified. The integration site buzzing. The neck buzzing. The construct's lattice brightening — the violet luminescence increasing in intensity as the processing cycle's preparatory function drew the reserves' rebuilt energy into whatever process the preparation served. The construct was using its recovered energy. Not for atmospheric conversion. Not for the habitable zone's maintenance. For something the construct's architecture had never performed in the twenty hours of the bond's existence.
9,989.
Mira crossed the habitable zone's boundary. Four meters from Shin. The processed air on her face. Three meters to go.
9,994.
9,997.
10,000.
The system interface transformed.
The shadow experience counter — the translucent display in Shin's upper-right peripheral vision whose values the grinding's months and the construct's amplification had accumulated — didn't reach the threshold so much as become it. The numbers dissolved. The counter's familiar format — numerator over denominator, the fraction's visual architecture that had tracked the progression's percentage — replaced by text that the system's interface rendered in characters whose brightness exceeded the counter's standard translucence. The text was visible. Solidly visible. Not the ambient peripheral display that the counter had been but the foregrounded priority notification that the system reserved for events whose significance the notification's visual prominence communicated.
**[Shadow Experience Threshold: 10,000 — REACHED]**
**[Initiating: Stat Allocation Protocol — Shadow Variant]**
**[Warning: Process requires stability. Current environment: HOSTILE]**
The warning. The system acknowledging the operational reality that the warning's content described — the hostile environment whose spider contacts and institutional surveillance and atmospheric hazards constituted the instability that the process's requirements identified as a threat to the process's completion.
Then the process started and the warning became irrelevant because the process didn't wait for the environment to comply.
The construct's pulse jumped. Sixty-one to sixty-five in a single beat. The rhythm accelerating — the cardiac frequency that the bond's template maintained increasing as the process's energy demand exceeded the sixty-one-beat cycle's throughput capacity. The construct needed more processing speed. The construct took more processing speed. The pulse's acceleration not a gradual climb but a step change — the crystal architecture's operational tempo ratcheting upward to serve the new function that the system's allocation protocol had activated.
Shin's body locked.
Not paralysis. Not the immobility that the nervous system's disruption produced. The lock was the bond's — the construct's accelerated pulse demanding the source's cardiac frequency's alignment with the new tempo, the sixty-one-beat rhythm that Shin's sinoatrial node had maintained for twenty years pulled upward by the crystal's accelerated demand. His heart rate climbed. Sixty-five. Sixty-eight. The acceleration involuntary — the autonomic nervous system's cardiac regulation overridden by the bond's frequency mandate, the construct's demand for throughput transmitted through the integration site's hybrid tissue to the cardiac control centers whose neural input the crystal's conduction pathway now included.
The stats began to move.
Not the explosive allocation that Level 1 had produced — the one hundred points distributed across the six stat categories in the instant that the level-up's completion triggered. This was different. The shadow variant. The stats didn't arrive. They reorganized. Shin's existing Level 1 allocation — the hundred points distributed across Strength, Agility, Endurance, Intelligence, Mana, and Perception — began shifting within his body like water finding new channels. The stats' distribution changing. The shadow experience's 10,000 data points informing the reallocation — the accumulated combat data, the grinding patterns, the kill methodologies that the months of experience had recorded now serving as the template that the shadow variant's allocation protocol used to optimize the stat distribution for the subject's actual capabilities rather than the system's standard allocation formula.
The redistribution hurt.
The stats were in his muscles and his nerves and his bones — the physical substrate that the system's allocation inhabited, the biological tissue whose enhancement the stat points' distribution produced. The reallocation meant the stats moved. The Strength points that the standard allocation had placed in muscle groups that Shin's combat style didn't prioritize — the large muscles, the power-generation groups — migrating toward the muscle groups that the shadow experience's data identified as the subject's actual functional priorities. The fast-twitch fibers in the hands. The stabilizers in the core. The precision muscles in the eyes' orbital complex.
Each stat point's migration was a sensation. The muscle's enhancement withdrawing from one location and redepositing in another — the biological process that the system's architecture conducted through the mana channels that the stat allocation's infrastructure utilized. The withdrawal felt like weakness — the specific muscle group losing the enhancement's support, the tissue reverting to the unenhanced baseline for the fraction of a second between withdrawal and redeposition. The redeposition felt like cramping — the receiving tissue's rapid enhancement producing the contraction that the tissue's sudden performance increase triggered.
Weakness and cramping cycling through his body. Legs. Arms. Torso. The stats redistributing through every muscle group simultaneously, the process's parallelism ensuring the reallocation's speed at the cost of the reallocation's comfort. His body shaking. The tremor that the concurrent muscle events produced — the systemic vibration of an organism whose physical substrate was being reorganized while the organism occupied the substrate.
The construct's pulse: seventy. Seventy-two. Climbing. The lattice's luminescence blazing — the violet glow intensified to the brightness that the accelerated processing's energy output produced, the crystal architecture radiating the thermal energy that the increased throughput generated. The habitable zone lurched. The boundary jumping outward to four-point-two meters as the processing output surged, then contracting to three-point-five as the energy diverted to the stat allocation protocol, then expanding again as the output fluctuated with the process's irregular demand cycle.
The integration boundary advanced. Two centimeters in seconds. The bond's accelerated pulse driving the conversion mechanism at the tempo that the seventy-two-beat rate demanded — the faster pulse processing more mana per minute, the increased processing providing more energy for the conversion, the conversion consuming more tissue per minute. The crystal-modified zone in his neck spreading — the translucent shimmer visible beneath the skin expanding toward the carotid sheath's now-close proximity. The modified tissue in his neck pulsing with the construct's accelerated rhythm. The secondary bond point conducting at an intensity that the sixty-one-beat baseline hadn't produced.
Mira reached him. Three meters. Inside the tether's radius. The healer dropping to her knees beside the patient whose body was shaking and whose heart rate the construct's accelerated pulse had pulled to seventy-two and whose integration boundary was advancing at a rate that the reader's sensor — pressed against the neck's skin as fast as the healer's hands could apply it — measured in centimeters per minute rather than centimeters per hour.
"His heart rate — seventy-two." Mira's voice carried the clinical data through the construct's intensified luminescence to anyone within range. "Rising. The construct is accelerating his cardiac rhythm through the bond. The integration boundary — advancing rapidly. Two centimeters in the last thirty seconds. The carotid sheath is—"
She checked the reader.
"Contact. The boundary has reached the sheath's exterior surface."
The construct's pulse hit seventy-five. The lattice blazing violet. The stat reallocation's process cycling through Shin's body — the cramping and the weakness and the reorganization that the shadow variant's optimization protocol conducted through the mana channels that the system's infrastructure maintained. The process was halfway done. Maybe less. The reallocation's scope encompassing all hundred stat points' redistribution across the body's entire musculature and the sensory systems and the neural networks that the stat categories' enhancement inhabited.
The contractor's instruments screamed data. The division's sensor array capturing the event's parameters at the resolution that the instruments' design provided — the construct's accelerated pulse, the bond's increased throughput, the integration's advancement, the subject's cardiac acceleration, the stat allocation's mana-channel activity. The contractor recording everything. The documentation's urgency visible in the operative's posture — leaning forward, the sensor unit held at arm's length toward the construct, the body's orientation fully committed to the data capture that the division's observation mandate required.
Vasquez was shouting something. The commander's voice lost in the construct's intensified luminescence's hum and the spiders' chitin-on-crystal clicking and the sidearms' discharge reports and the sound of Shin's own pulse in his ears — seventy-five, seventy-seven, the rhythm climbing toward whatever rate the process's completion demanded.
He couldn't move. The bond held him. The construct's pulse dictated his pulse. The system's process ran through his body with the indifference of software executing on hardware that the software's designers had specified as compatible but whose compatibility the software hadn't verified with the hardware's input.
Seventy-nine. Eighty.
The construct's pulse at eighty and climbing, and Shin locked against the crystal with the system rewriting his body's stat distribution while the spiders surged against a perimeter that was running out of bullets and the healer's reader showed the integration boundary touching the sheath that contained the nerve that controlled the heart that the construct was already controlling.
Eighty-two. Eighty-three.
The violet light turned white at the edges.
