Extra's Revenge: Reincarnated As A Slave

Chapter 173: Prince of Darkness



The Labyrinth trembled.

Stones that had stood for millennia cracked under pressure that transcended physical force.

The protective dome over the Sanctuary flickered and dimmed, its enchantments struggling against mystical interference operating at scales they were never designed to withstand.

Then the Prince of Darkness emerged.

The passage leading from the Labyrinth’s deepest sections simply ceased to exist, torn apart by the creature’s arrival. What replaced it was a nightmare given form—a being whose very presence made reality recoil in rejection.

The Prince of Darkness stood approximately fifty meters tall, its form defying classification. It possessed characteristics that suggested multiple creatures merged into an impossible whole—draconic wings spreading thirty meters across, a leonine body covered in scales that absorbed light rather than reflecting it, multiple serpentine heads emerging from a central mass, each one bearing eyes that glowed with malevolent intelligence.

But most terrifying was the Chaos Energy radiating from its form.

Not the wild, undirected corruption of normal Chaos Dwellers, but controlled power operating with deliberate intent. The Prince wasn’t just a manifestation of Chaos—it was Chaos given consciousness, purpose, and devastating capability.

Its mystical pressure made Valdris’s Devil-tier presence seem insignificant by comparison. This was power that approached the legendary entities from ancient times, beings whose capabilities had shaped continents and destroyed civilizations.

Tier 4 Chaos Dweller.

A classification that shouldn’t exist according to contemporary understanding, which represented evolution beyond what modern practitioners believed possible.

All seven of the Prince’s serpentine heads turned toward the Sanctuary simultaneously, eyes analyzing the destruction with intelligence that transcended animal awareness.

When it spoke, the voice resonated from all seven heads at once, creating harmonics that made listeners’ consciousness ache from mere exposure.

"WHO DARES DISTURB MY SLUMBER?

" The question carried mystical weight that forced every conscious being in the Sanctuary to their knees. Even Valdris felt pressure compelling submission, though his Devil-tier capabilities allowed him to resist where others could not.

"CENTURIES OF SILENCE, BROKEN BY COMBAT THAT ECHOES THROUGH MY DOMAIN. WHO POSSESSES SUCH ARROGANCE?"

All seven heads fixed on Valdris simultaneously, recognition dawning in eyes that had witnessed millennia.

"A DEVIL. ONE OF THE SURFACE REALM’S SUPPOSED MASTERS, INVADING TERRITORIES THAT ARE MINE BY RIGHT OF CONQUEST."

Valdris spread his wings in a gesture combining respect and defensive preparation. "Prince of Darkness, this is a misunderstanding. I didn’t come to challenge your domain—"

"SILENCE!"

The command carried force that made Valdris stumble backward, his Ethereal Form technique activating reflexively against mystical assault.

"YOU INVADED THE LABYRINTH OF DARKNESS. YOU BROUGHT COMBAT TO MY DOORSTEP. YOU DISTURBED REST I HAVE MAINTAINED FOR CENTURIES. THESE ARE NOT MISUNDERSTANDINGS—THESE ARE PROVOCATIONS DEMANDING RESPONSE."

"I was investigating a triggered ancient arrangement," Valdris tried to explain, recognizing that avoiding combat would serve his interests better than engaging a Tier 4 entity. "Someone displaced a Divine-grade artifact, and my duty required—"

"YOUR DUTY IS IRRELEVANT. YOUR INVESTIGATIONS ARE MEANINGLESS. YOUR PRESENCE HERE IS VIOLATION."

The Prince of Darkness’s wings spread to full extension, creating shadow that encompassed the entire Sanctuary. Chaos Energy gathered around its form with intensity that made the ambient mystical pressure feel suffocating.

"THIS LABYRINTH IS MINE. THESE DEPTHS ARE MINE. THE NEPHILIM SURVIVE BECAUSE I PERMIT THEIR EXISTENCE. BUT YOU—"

All seven heads opened simultaneously, revealing maws that contained concentrated destruction.

"—YOU WILL LEARN WHY SURFACE DWELLERS FEAR THE DARKNESS."

Seven beams of pure Chaos Energy erupted toward Valdris, each one carrying power sufficient to obliterate anything short of Divine classification.

Valdris activated multiple defensive Artifacts simultaneously, Divine-grade equipment creating barriers that intercepted the assault before it could strike him directly.

The beams impacted his defenses with force that shattered stone throughout the Sanctuary, the collision between Tier 4 Chaos and Devil-tier mystical protection creating devastation that extended for hundreds of meters.

"YOU POSSESS NOTABLE DEFENSES," the Prince observed, almost conversational despite the ongoing assault. "BUT DEFENSE ALONE WILL NOT SAVE YOU."

It moved.

Fifteen meters of impossible biology crossed the distance between them with speed that defied physics, the Prince’s massive form appearing beside Valdris before the Devil could fully react.

Claws that could shred Divine-grade armor struck toward Valdris’s position, each one infused with Chaos Energy operating at sequences that transcended normal classification.

Valdris teleported away using his bracers, reappearing fifty meters distant. But the Prince anticipated the movement, one of its serpentine heads already positioned to intercept.

"Chaos Art, Mutation Technique, Sequence #0: Ultimate Evolution!"

The head’s maw opened, and reality inside distorted into forms that biology rejected as impossible. Valdris felt his physical body attempting to mutate, his carefully maintained Devil form trying to transform into something the Mutation Technique imposed.

He countered immediately with his own Sequence #0 defense.

"Soul Art, Fortress Technique, Sequence #0: Absolute Immutability!"

His consciousness became the anchor that prevented transformation, willpower overriding the Mutation Technique’s attempt to reshape him. But the effort required tremendous Ether expenditure, and the Prince showed no signs of slowing its assault.

Another head attacked from a different angle, this one using a different Technique entirely.

"Chaos Art, Entropy Technique, Sequence #0: Temporal Acceleration!"

The space around Valdris aged at impossible rates. Stone became dust, air became vacuum, even the mystical energy sustaining his form began degrading as entropy accelerated beyond natural limits.

Valdris responded with a counter-Technique that demonstrated why Devils were considered peak mortal existence.

"Chaos Art, Reversal Technique, Sequence #0: Universal Inversion!"

The entropy reversed, time flowing backward within the affected space, restoring what had been degraded while turning the Prince’s attack back on itself.

But the Prince possessed seven heads, and each one could attack independently while the others created openings.

"IMPRESSIVE REVERSALS," it acknowledged, amusement in its multiple-toned voice. "BUT CAN YOU COUNTER SEVEN SIMULTANEOUS ASSAULTS?"

All seven heads attacked at once, each using different Chaos Art Techniques operating at Sequence #0 or #1:

Mutation attempted to transform Valdris’s form.

Entropy accelerates decay beyond resistance.

Corruption was spreading through his mystical defenses.

Perversion twisted the fundamental rules governing his existence.

Degeneration reduced his capabilities toward baseline mortality.

Contamination started to poison the Ether sustaining his techniques.

Paradox was creating logical impossibilities that his consciousness couldn’t resolve.

The combined assault exceeded what any single practitioner could counter through conventional means. Even Valdris, with his Devil-tier capabilities and Divine-grade equipment, found himself overwhelmed by the sheer multifaceted nature of the attack.

The Prince of Darkness was simply too strong!
