Harem Master: Seduction System

Chapter 438: The Death of a Demon

The subterranean cavern was a furnace of pressurized malice and boiling blood. The ambient air, thick with vaporized marrow and scorched ozone, seared the lungs with every intake. In the absolute center of the ruined geode, the Abyssal Bone Demon Emperor raised a colossal, regenerating arm to block a descending arc of pure, white sword intent.

Corbin’s boots ground into the melting obsidian, the heavy tread shearing off as his center of gravity shifted forward. His Unyielding Warlord Physique was actively failing. Deep, jagged lacerations marred his exposed torso, the flesh cauterized instantly by the ambient heat, yet the underlying musculature trembled uncontrollably. The system-enhanced durability buffers had long since burned out, leaving his raw, mortal physiology to bear the catastrophic recoil of repeatedly clashing with a sovereign entity.

“Die!” Corbin roared, his vocal cords scraping together, producing a sound akin to grinding iron.

He wrenched his greatsword sideways, utilizing the torque of his hips to violently redirect the Absolute Tyrant Cleave. The blade bit into the Demon Emperor’s elbow joint. The sheer density of the entity’s alchemically hardened bone screeched against the Weapon Essence. Shards of calcified marrow exploded outward like shrapnel.

The Demon Emperor did not recoil. Its massive, horned helm tilted downward, the burning crimson pinpricks in its eye sockets tracking the warlord’s desperate exertion.

“Your foundation crumbles, instrument of the heavens,” the Demon Emperor’s psychic resonance vibrated through the cavern floor, sending hairline fractures spreading beneath Corbin’s boots.

The entity thrust its remaining, intact hand forward. The ambient blood pooling across the cavern floor rushed upward, defying gravity, weaving into a massive, concentrated sphere of pure, highly corrosive Corrupt Qi.

“Abyssal Annihilation Pillar.”

A beam of pitch-black, pressurized necrotic energy erupted from the Demon Emperor’s palm, encompassing a thirty-foot radius. The attack did not carry concussive force; it carried absolute, molecular degradation.

Corbin’s pale blue eyes tracked the incoming column of darkness. His internal interface flared with blinding crimson alerts.

[System Notification: Lethal Necrotic Threat Detected.]

[Warning: Heavenly Martial Points Depleted. Evasion protocols compromised. Muscular integrity at 18%.]

Corbin planted the flat of his greatsword against the stone, dropping to one knee, and angled the blade upward to form a sloped barricade. He channeled the last dregs of his Tyrant Emperor Domain into the steel. The black beam struck the domain. The gray energy instantly began to boil and peel away, the necrotic magic eating through the conceptual barrier. The edges of Corbin’s greatsword superheated, the metal warping and groaning under the thermal and corrosive stress.

Corbin tasted blood at the back of his throat. His ear canals wept hot fluid, the pressure in his skull reaching critical mass. He was entirely pinned, forced to channel every microscopic fraction of his remaining stamina simply to prevent the beam from erasing him from the physical plane.

Fifty yards away, concealed perfectly within the shadows of the collapsed entrance, Alaric observed the structural breakdown of the warlord’s defenses.

The Archmage leaned upon his wooden staff, his breathing completely even. His ruby eyes darted between the flashing system prompts visible only to his advanced perception and the exposed, glowing green Primordial Core currently visible within the Demon Emperor’s open ribcage.

‘The entity has abandoned defense to secure the kill,’ Alaric analyzed, his mind a void of pure calculation. ‘Corbin is expending his final reserves to survive the bombardment. The core is unprotected.’

Alaric calculated the transactional mechanics of the warlord’s system. He had watched Corbin effortlessly purge curses and regenerate tissue through point expenditure.

‘A system functions on a strict reward matrix,’ Alaric deduced, his grip tightening imperceptibly on his staff. ‘If the host delivers the killing blow to an entity of this magnitude, the system will register a major quest completion. The resulting influx of experience or points will trigger an instant restorative protocol or a rank advancement. Corbin will recover his strength.’

That was an unacceptable variable. Alaric needed the warlord entirely hollowed out, bereft of points, stamina, and systemic safety nets.

‘The transaction must be severed,’ Alaric decided. ‘The final blow belongs to me.’

He could not simply cast a spell from his current position. The Imperial Consorts and Ling Ying were merely paces away, recovering their breath. If he unleashed his true mana, his alibi as a weak healer would evaporate instantly. He needed a proxy. He needed chaos.

Alaric closed his eyes. Within the sub-spatial confines of his own mana pool, he invoked the spell ‘Mirror Projection’.

Beside the trembling form of Ling Ying, the ambient light faintly refracted. A flawless, tangible construct of the gray-cloaked scholar materialized, leaning heavily on its staff, its breathing perfectly synced to mimic exhaustion.

Simultaneously, the true Alaric invoked ‘Spatial Rift’.

He stepped backward, his physical body slipping smoothly into a tear in the fabric of reality. He vanished from the material plane, entering the dark, pressurized corridor between dimensions.

Within the spatial void, Alaric moved with blinding velocity. He stripped away the gray scholar’s cloak, letting it drift into the ether. He reached into his spatial ring, retrieving a set of tattered, blood-stained crimson and gray robes he had stripped from a fallen cult elder hours prior. He donned the heavy fabric, pulling the frayed cowl deep over his head, entirely obscuring his face in impenetrable shadow.

He retrieved a weapon. It was not a magical artifact or a legendary blade; it was a mundane, heavy profound-steel broadsword taken from a dead Iron-Blood mercenary.

Alaric did not intend to use traditional sword intent. He was an Archmage. He would mimic martial arts through the absolute, overwhelming application of close-quarters elemental reinforcement.

‘Azure Spirit Lion Blood Essence,’ Alaric commanded internally.

His physical heart slammed against his ribs with the force of a battering ram. The dormant, majestic bloodline within his veins ignited. His musculature instantly condensed, taking on the density of star-iron. His physical strength skyrocketed, pushing past the boundaries of a mortal frame.

He raised the mundane broadsword. He did not flood it with Battle Aura. He layered four distinct, highly compressed spells over the steel.

‘Elemental Fusion Arc,’ Alaric chanted silently.

He wove ‘Ignition’ to superheat the edge, ‘Gale Force’ to eliminate aerodynamic drag, and ‘Lightning Surge’ to paralyze the target’s nervous system upon impact. Finally, he coated the entire construct in ‘Spatial Severance’, a spell designed to ignore physical density by separating the atomic bonds of whatever the blade touched.

The mundane sword vibrated violently, threatening to shatter in his hands from the sheer, conflicting magical pressure.

Alaric navigated the spatial corridor, positioning himself exactly three feet behind the Demon Emperor’s exposed ribcage.

On the physical plane, the battle had reached its absolute climax.

The Demon Emperor cut the Abyssal Annihilation Pillar. The entity took a massive, thundering step forward, raising its colossal foot to physically crush the kneeling, exhausted Corbin.

Corbin’s system interface screamed with a final, desperate prompt.

[System Notification: Core Exposed. Target Vulnerability: 100%. Recommended Action: Execute.]

Corbin abandoned his defensive posture. He ignored the descending, blood-armored foot. He gripped the hilt of his greatsword, his knuckles turning white, his forearms tearing as the muscle fibers snapped under the strain. He channeled the absolute last drop of his physical vitality into the blade.

“Absolute Tyrant Cleave!” Corbin roared, thrusting the greatsword upward, aiming perfectly for the pulsing green Primordial Core within the demon’s chest.

At that exact, microscopic fraction of a second, the fabric of space directly behind the Demon Emperor tore open.

The air pressure in the cavern violently plummeted. A figure cloaked in tattered crimson and gray robes stepped out of the void.

To the exhausted observers—Commander Jin, the Imperial Consorts, and the struggling mercenaries—it appeared as though a hidden, terrifyingly powerful elder of the demonic cult had suddenly materialized from the shadows to intervene.

Alaric did not hesitate. His boots touched the obsidian, and he swung the mundane broadsword.

The fused elemental magic and spatial severance masking the blade sheared completely through the Demon Emperor’s back. The hardened, alchemically forged bone, which had resisted the continuous bombardment of the Imperial Vanguard, offered absolutely no resistance to the spatial magic.

The dark blade passed cleanly through the ribcage.

CRACK.

The sound of the Primordial Core shattering was not loud, but it was absolute. It resonated in the soul of every living creature in the cavern.

Alaric’s blade struck the glowing green crystal a mere millisecond before Corbin’s greatsword could breach the front of the ribcage. The core fractured into a thousand pieces, the putrid green light instantly dying.

Corbin’s upward thrust met only empty air and collapsing bone dust as the structural integrity of the Demon Emperor vanished.

The colossal skeletal monstrosity froze. The burning crimson light in its eye sockets flickered wildly, then abruptly snuffed out. The heavy, pulsating plates of blood-armor instantly lost their cohesion, liquefying into a torrential downpour of foul, mundane blood that splattered across the cavern floor.

The skeletal framework crumbled. Eighty feet of hardened marrow collapsed inward, reducing the terrifying sovereign entity to a massive, smoking pile of white ash and shattered fragments.

The Primordial Spirit, unmoored from its physical anchor and its core shattered, dissolved into the ambient air, breaking down into a thick, swirling mist of raw, untethered Corrupt Qi.

It was not truly dead. The lore of the ancient eras dictated that a Primordial Spirit of a Demon Emperor could not be permanently annihilated by mere physical or elemental destruction. Without the purifying compression of the full ‘Seven-Star Heaven-Lock Array’, the core’s shattering merely dispersed the spirit into the deep, subterranean leylines of the earth. It would slumber, slowly gathering malice, inevitably destined to reconstitute its consciousness in three hundred years.

But for now, the immediate threat was neutralized.

Alaric, completely hidden beneath the frayed cowl, stood amidst the falling ash. The mundane broadsword in his hand, having delivered the apocalyptic blow, finally succumbed to the immense magical stress. The steel shattered into a dozen pieces, falling from the hilt to clatter against the stone.

He did not linger. He had secured the kill. He had severed the transaction.

Before the dust could even begin to settle, Alaric took a single step backward, slipping seamlessly back into the closing spatial rift, vanishing from the physical plane as swiftly as he had arrived.

Corbin crashed forward, his chest slamming against the obsidian floor.

His greatsword slipped from his numb fingers, clattering loudly against the stone. He did not have the strength to rise. His Unyielding Warlord Physique deactivated, leaving his raw, torn musculature exposed to the blistering heat of the cavern. His vision tunneled, the edges of his sight turning black.

He stared at the pile of ash before him, waiting for the familiar, triumphant golden glow of his interface. He waited for the surge of restorative energy, the level up notification, the influx of Heavenly Martial Points.

The system interface remained static, displaying a cold, indifferent string of text.

[System Notification: Target ‘Abyssal Bone Demon Emperor’ Eliminated.]

[Combat Analysis: Fatal blow delivered by Unknown Entity. Host Contribution: 48%.]

[Quest ‘The Grandmaster’s Trial’ Progress Updated. Primary Kill Condition: Failed.]

[No Experience Awarded. No Heavenly Martial Points Awarded.]

Corbin’s pale blue eyes widened in sheer, unadulterated disbelief. The exhaustion in his bones was suddenly eclipsed by a wave of cold, hollow rage.

‘Failed?’ Corbin’s mind ground against the reality. ‘Someone stole the kill. An unknown entity.’

He forced his head up, his neck muscles screaming in protest. He looked at the spot where the dark-robed figure had appeared. There was nothing there. Just empty air and falling ash. The interloper had vanished without leaving a single trace of Battle Aura or elemental residue.

Fifty yards away, the sheer silence of the cavern was broken by the heavy, metallic clatter of armor.

Noble Consort Cui Yulan landed heavily on the obsidian floor.

She did not touch down with the grace of a goddess. Her knees buckled upon impact, forcing her to lean entirely upon the shaft of her Heaven-Piercing Thunder Lance to prevent herself from collapsing. Her dark violet profound-steel armor was heavily cracked, entire plates missing from her shoulders and flanks. Her breath came in ragged, wheezing gasps, the exhalations scorched with the internal heat of her severely strained meridians.

The Nine-Heavens Violet-Gold Suanni bloodline was completely dormant, its ignition having pushed her physical vessel to the absolute brink of structural failure. Blood leaked steadily from her nose and the corners of her mouth, dripping onto the charred stone.

She looked up, her silver eyes scanning the devastation.

The Demon Emperor was reduced to ash. The immediate, apocalyptic pressure crushing the vanguard had lifted.

Commander Jin and Commander Vane were slowly pushing themselves up from the floor, their armor dented, their faces pale and drawn from the profound vitality drain they had endured. Imperial Consort Su Xinyue and Imperial Consort Zhao Mengxue remained near the entrance, leaning against the cavern walls, their breathing erratic as they struggled to re-circulate their stagnant Qi.

Every single pair of eyes in the cavern was locked onto the center of the battlefield. They had all witnessed the sudden materialization of the dark-robed figure. They had all seen the impossible, flawless strike that had severed the Demon Emperor’s core.

“Who…” Cui Yulan coughed, the metallic taste of blood heavy on her tongue. “Who was that?”

“A cult elder?” Commander Jin gasped, gripping his golden halberd, his eyes frantically scanning the shadows. “Did they betray their own sovereign to steal its power?”

“The strike bypassed the alchemical bone completely,” Commander Vane analyzed, his scarred face tight with pain as he forced himself to stand. “It wasn’t a standard martial art. The blade just… passed through.”

The tension in the Inner Sanctum did not dissipate with the death of the Demon Emperor; it amplified, warping into a heavy, suffocating paranoia. The surviving forces were completely exhausted, their Dantians empty, their bodies battered. And now, they were acutely aware that an unknown, terrifyingly powerful entity was operating within the shadows of the catacombs, capable of bypassing sovereign-tier defenses and vanishing without a trace.

Alaric’s physical body materialized flawlessly back into his Mirror Projection standing near the cavern entrance. The projection seamlessly dissolved the moment his true flesh occupied the space.

He leaned heavily on his wooden staff, letting out a perfectly timed, ragged exhale, acting precisely like a weak mage overwhelmed by the lifting of the demonic pressure.

‘The warlord is broken. The system transaction is denied,’ Alaric noted, his ruby eyes observing the kneeling, furious form of Corbin. ‘He possesses no points to heal himself. He is a mortal man trapped in a ruined body.’

Alaric shifted his gaze to Cui Yulan. The Noble Consort was entirely spent, her formidable lightning silenced.

The stage was cleared of all major threats. But the environment itself remained highly volatile.

The Primordial Spirit had dissolved, but the raw, untethered Corrupt Qi had not vanished. Without the physical vessel to anchor it, the immense volume of demonic energy released by the shattered core began to react erratically to the sudden vacuum.

The thick, swirling mist of black Qi did not drift toward the ceiling. It began to aggressively pool and swirl near the obsidian floor. The energy twisted into tight, violent cyclones, tearing across the chamber like localized hurricanes of malice.

The energy was actively seeking a new conduit. It sought flesh, blood, and a Dantian to inhabit.

“The ambient Qi is destabilizing!” Zhao Mengxue shouted, her voice tight with renewed alarm as a cyclone of black mist tore past her position, scorching the stone. “The spirit is dispersed, but the raw energy is looking for a host!”

“Establish the purification perimeters!” Cui Yulan commanded, attempting to stand straight, but a violent tremor wracked her legs, forcing her to heavily lean on her lance once more. “Do not let the mist enter your meridians!”

Commander Jin and the surviving Imperial Guards scrambled to form a defensive ring, attempting to project their meager, remaining Battle Aura to push back the encroaching cyclones.

Alaric watched the swirling, desperate energy, his Archmage intellect effortlessly calculating the atmospheric pressure and the flow of the leylines.

‘The energy is dense enough to trigger a localized spatial collapse if left unanchored,’ Alaric deduced, his eyes narrowing slightly as he finalized his ultimate snare. ‘I need them entirely isolated, away from the prying eyes of the Vanguard, and deep within the labyrinth of these catacombs. I need a sealed environment where no system and no guard can intervene.’

He reached out with a microscopic thread of mana, preparing to guide the volatile, swirling Corrupt Qi exactly where he needed it to go.
