Chapter 15: Residual Threat
The acrid stench of sulfur exploded into the air as the secondary containment barrier fractured in two.
Leo surged through the smoke toward the changing rooms.
It was subtle, like the metallic tang of burnt iron mixed with stale blood. Most cadets bustling toward the morning bouts failed to notice it, but several senior instructors walked with hurried, tense strides.
Leo Vance detected the scent the moment he stepped out of the male dormitory.
In the original novel’s timeline, this precise anomaly occurred three weeks later during a routine perimeter sweep. A sealed fault beneath the outer training fields had suffered a micro-fissure, allowing residual shadow beasts to materialize near the academy walls. In the original story, several cadets were severely wounded, and a highborn heiress barely survived the ambush.
This time, the breach had triggered early.
Leo altered his route, heading toward the eastern logistics depot rather than the Grand Coliseum. Barrier plate maintenance could wait.
By mid-morning, the tournament matches proceeded according to schedule. Overhead magic mirrors rotated across the arena, projecting duels to the roaring stands where noble house scouts and imperial officers evaluated the combatants. Caelum Voss was slated for a premier afternoon match.
Leo was carrying a stack of barrier plates near the eastern colonnade when a sharp scream ripped through the morning air.
The alarm originated from the secondary sparring field located just beyond the Coliseum’s eastern wall, a zone reserved for warm-ups and unranked drills.
Cadets scattered in panic as instructors shouted emergency containment commands.
Leo dropped the barrier plates and sprinted toward the disturbance.
The secondary field was in complete disarray.
Three residual shadow beasts had fully condensed from the earth. They resembled massive black-iron wolves forged from billowing smoke and razor-sharp dark edges. Their physical forms fluctuated constantly, allowing steel practice blades to pass harmlessly through their smoke-like hides while basic elemental spells barely slowed their advance.
Several second-year cadets were trapped in the lane. Two lay unconscious on the sand, while a third cadet desperately dragged a wounded girl backward.
Elara Snowveil stood directly in the vanguard.
She had been utilizing the secluded field for private drills between her tournament matches. Her pure-white hair was tied into a high combat ponytail, her practice rapier coated in shimmering frost aura.
A dense barricade of ice erupted from the sand before her, but the largest shadow beast slammed into it with terrifying momentum, splintering the frozen wall into shards.
Elara released three concentrated frost javelins in rapid succession. Two penetrated the smoke torso without dealing structural damage, while the third only caused the beast to stagger for half a second.
The creature crouched and launched itself directly toward her exposed flank.
Leo reached the edge of the sparring lane at the exact same moment.
From the novel’s hidden lore, Leo knew the anatomical secret of residual beasts: their dense shadow core materialized behind the left shoulder joint for precisely three seconds following a leaping attack before dissolving back into shifting smoke.
Leo did not waste breath shouting warnings that a lower-mid cadet had no authority to give.
He surged forward with an explosive wind-enhanced step, closing the distance in the blink of an eye. He carefully throttled his output, channeling just enough refined mana to execute a clean, decisive strike.
Swinging his wooden practice blade with pinpoint accuracy, Leo drove the tip straight into the beast’s left shoulder joint at the apex of its leap.
The wooden sword struck solid core.
A violent shockwave of black smoke erupted outward. The beast let out a shrill, shrieking howl as its smoke structure collapsed, dissolving into harmless wisps of dark vapor.
Elara’s golden eyes locked onto Leo in stunned disbelief.
Before she could speak, the second shadow beast lunged from the left flank.
Leo stepped smoothly between Elara and the attacking creature, raising a compressed wind barrier to absorb the impact. The kinetic force pushed him back half a step, maintaining the plausible limits of an average second-year cadet.
The barrier held long enough for Elara to capitalize on the opening. Recognizing the weak point Leo had exposed, she drove a concentrated ice lance straight through the second beast’s left shoulder.
The creature shattered into freezing mist.
The third beast attempted to wheel toward the injured students, but two senior combat instructors arrived on the scene, encasing the remaining monster in a high-tier earth binding until it dispersed.
Silence descended over the secondary field.
Cadets stared in shock, instructors secured the perimeter, and several noble observers gathered along the outer railings, murmuring among themselves.
Elara stood three paces from Leo. Her chest rose and fell in measured breaths, her sharp golden eyes studying his face with intense scrutiny.
"You knew where to strike," she said in a hushed, guarded tone.
Leo kept his expression completely flat.
"A lucky swing," he replied smoothly.
Elara’s eyes narrowed. "That was not luck. You struck the exact anatomical weak point twice."
"Then keep your observations to yourself, Rank 1," Leo answered quietly. "Some things are better left unsaid in public."
Her fingers tightened around the hilt of her rapier. For a moment, it seemed she intended to press further, but she turned back to assist the medical team tending to the wounded cadets.
Leo gathered the dropped barrier plates and exited the field before the arriving crowd could corner him with questions.
Within his chest, his mana channels pulsed with quiet, satisfied warmth, having greedily absorbed the ambient residual smoke dispersed during the clash.
By late afternoon, rumors of the skirmish had spread throughout the academy. Cadets whispered about the unranked student who had intercepted two residual monsters alongside House Snowveil’s prodigy.
Before his own scheduled match, Caelum Voss intercepted Leo near the armory corridor. His public demeanor remained impeccably noble, yet a dark, unstable tension lurked beneath his gray eyes.
"You were present at the secondary field," Caelum said in a low, strained voice.
"Assigned to logistics," Leo replied.
"You stepped in front of Elara," Caelum continued, his knuckles whitening against his sword belt. "The instructors noticed, and my house scouts noticed. A residual beast breach during Ranking week is highly irregular, and you reacted as if you anticipated the threat."
He glanced down the corridor to ensure they were unobserved before stepping closer.
"I need another recording soon," Caelum whispered, his voice trembling with quiet desperation. "The bottleneck pressure is intensifying, and Elara is visibly distracted. Be ready when she comes to your quarters."
Without waiting for a response, Caelum turned and strode briskly toward the tournament tunnel.
Leo watched his retreating figure with a cold, calculating gaze. Every event was accelerating the collapse of House Voss’s perfect reputation.
---
Across the academy, inside the private female changing suites, Elara Snowveil stood before the mirror and stared at her own hands.
Her fingers were steady, and her frost mana had circulated flawlessly during the battle.
Yet her thoughts were in complete turmoil.
Leo Vance had reached the beast before her. He had struck the hidden core with absolute certainty, stepping directly between her and the monster without a fraction of hesitation.
"A lucky swing," he had claimed.
She did not believe him for a second.
This was the same man who held her pinned against the sheets, the same man whose dominant touch made her body betray every noble vow she possessed, and the same man whose whispered commands still echoed through her dreams.
He had defended her without hesitation, asking for nothing in return.
A strange, unfamiliar heat twisted deep within Elara’s chest.
Caelum would visit her later to inquire about the battle. He would offer gentle words of comfort, only to inevitably steer the conversation toward another requested night with Leo.
A bitter realization settled in her heart: Caelum viewed her surrender as a tool for his ambition, while Leo claimed her body with raw, unyielding dominance.
Elara adjusted her academy blazer, took a steadying breath, and pushed open the door to the sunlit corridor.
Enforcer captain shouted through the settling dust: "Cadet Vance, Lady Snowveil! Step away from the carcass!"
