Chapter 75 – Shadow Strike into the Abyss

"To confront the abyss, one must first embrace the darkness within."

The Abyssal Veins – Approaching the Black Fortress

The sky above the Abyssal Veins churned with roiling crimson clouds, occasionally split by jagged forks of dark lightning that crackled with eerie silence. Below, the land was scarred and cracked, stained with veins of molten soul-essence that snaked across the earth like living fire.

Perched silently on a jagged ridge overlooking the vast fortress, Zero's black robes melded perfectly into the swirling shadows. The Chaos Ring on his waist thrummed softly, its pulse synchronized with his own heartbeat. The faintest glow emanated from the runes etched on his gauntlet as data streamed directly into his mind.

The fortress itself was a nightmarish construction of black obsidian. Jagged spires pierced the crimson mists, and chains of dark iron bound the towering structure to the earth, as if to contain some unholy force within.

Zero's gaze was cold and calculating. He unfolded a three-dimensional projection from the Chaos Ring: a layered map of the fortress's outer and inner defenses, patrolling units, arcane wards, and magical traps. Faint, shimmering glyphs marked energy flows, potential ambush points, and ritual sites.

Chaos Ring AI: "Outer patrol count: fourteen. Detected arcane traps along northern corridor: twelve. Ritual energy spike detected near central sanctum: 70% completion estimated. Estimated enemy alertness: high."

Zero's lips pressed into a thin line. The enemy was prepared—and the window to act was closing fast.

Without hesitation, he folded the projection and slipped into the deep shadows below.

Silent Steps and Shadow Veils

The fortress's perimeter was guarded by spectral sentinels—ghostly figures clad in tattered crimson armor, their hollow eyes glowing faintly with cursed fire. They drifted like smoke along the battlements, their ethereal forms passing through walls and floors, sensing all movement.

Zero moved like a shadow incarnate, his footsteps making no sound on the jagged stones. His breath was steady, his body coiled like a spring ready to unleash.

Ahead, a faint shimmer betrayed a rune trap designed to ensnare souls—chains of spectral fire that would burn not flesh but spirit.

Zero's fingers flicked swiftly. A veil of chaotic shadows enveloped him, absorbing and nullifying the trap's glow.

Chaos Ring: "Trap bypassed. Proceeding."

Two sentinels patrolled nearby, their armor crackling with dark energy. Zero drew the Shadowpiercer, its black blade humming softly as it absorbed the ambient darkness.

In a flash, he was behind the first sentinel, slicing through the tendons in a single motion. The figure crumpled soundlessly.

The second turned, sensing a presence, but Zero's hand clamped over his throat. The light faded from the sentinel's eyes before a single breath escaped.

Zero released the body and melted back into the darkness, moving deeper into the fortress.

The Obsidian Labyrinth

Within the fortress, obsidian walls twisted into a maze of corridors carved with abyssal runes that pulsed ominously. The oppressive energy pressed against Zero's soul—the taint of the Ashen Crown infecting everything.

He consulted the Chaos Ring, which displayed shifting patrol rotations and the location of the ritual chamber—a massive cavern deep in the fortress core.

Every step was a deadly dance, navigating illusions, soul traps, and cursed glyphs meant to drain the very life force of intruders.

Before a massive door sealed with a complex Soul Binding Seal, Zero paused. The rune pulsated with dark energy, threatening to sap his spiritual core on contact.

Raising Shadowpiercer, he traced a counter-rune in the air. A surge of pure chaos qi flowed through his fingertips.

The seal shattered with a thunderous crack.

Chaos Ring: "Seal bypassed. Spiritual drain avoided."

He slipped inside.

Heart of Darkness – The Ritual Chamber

A cavernous hall opened before Zero. Flickering crimson runes cast grotesque shadows on the walls. The air was thick with unholy power.

At the center, a massive summoning circle burned with arcane energy. Hooded cultists chanted a dark incantation in a language older than time. Above them, a swirling vortex tore open—a bleeding wound in reality itself.

Chaos Ring: "Ritual progress: 70%. Demon portal activation imminent."

Zero's grip tightened on Shadowpiercer, its runes blazing with chaotic light.

Before he could strike, a soft whisper cut through the darkness.

The Silver Light

From the shadows emerged a woman bathed in silvery light, moving with practiced grace and caution.

"You're not alone," she said quietly.

Zero's eyes narrowed beneath his mask. The aura she radiated was potent—cultivated, yet distinct from the Ashen Crown's corruption.

"I am Liora," she said, voice steady but filled with quiet regret. "I once served the Ashen Crown. Now, I fight to undo the damage."

She produced a small crystal shard glowing with pure white light.

"Use this to disrupt the ritual's core. It's the only way."

Zero studied her carefully, sensing no deception.

"Why help me?"

"Because if this ritual succeeds, nothing will remain to save," Liora answered. "Including me."

The Battle Begins

The cultists faltered at the intruders' presence, their chanting breaking.

With a roar, they surged forward, dark magic swirling and weapons drawn.

Zero moved like a storm—his blade flashing, severing limbs and cutting down spells before they could form.

Liora released bolts of silver qi, precise and deadly.

Together, they reached the summoning circle.

Zero drove the crystal shard into the arcane core.

The vortex convulsed violently.

The Demon Lord Awakens

From the trembling portal, a monstrous shadow emerged. Its form was massive, twisted with blackened horns curling like scorched roots, eyes ablaze with ancient hatred.

The demon lord had been bound for centuries—now prematurely freed.

Zero's blade gleamed as chaos qi surged.

"This ends now."
