Chapter 404: The Mark of the Void

In the center of the dark nest, Ethan’s Amethyst Eyes locked onto a sphere of absolute obsidian. It didn’t reflect the dim violet glow of his pupils; it seemed to pull the very air into its center. As his fingers brushed the surface, the viscous, light-eating smog that filled the cavern vanished—violently sucked into the orb.

"Ethan, wait!" Anne shouted, her voice thin in the sudden vacuum.

The moment his skin made contact, the orb superheated. Ethan’s eyes flew wide as a searing, agonizing heat surged up his arm. He tried to recoil, to fling the object away, but it was fused to his palm as if part of his own body. A guttural scream ripped from his throat.

Violent arcs of amethyst lightning erupted from his skin, lashing out at the cavern walls. His body began to swell, his muscles bulging under the strain of a power that felt utterly untamed. The black smog didn’t just disappear; it began to crawl up his limbs like a living parasite, veiling him in a shroud of darkness.

Suddenly, the violet radiance in his eyes intensified into a blinding, celestial glare. The black shroud seemed to shriek, recoiling from the light of the Amethyst Eyes as if terrified. The smog retreated into the orb, and with a final, sickening pulse, the sphere sank directly into Ethan’s palm.

A black spiral tattoo bloomed across his skin, coiling from his fingertips, up his forearm, and disappearing beneath his shoulder.

Ethan stood frozen, his chest heaving. With a single, unintentional twitch of his hand, the entire cavern groaned and trembled, dust raining from the ceiling.

[Careful, Host!] Crul’s voice echoed with urgent static. [Your cultivation has just undergone a violent, exponential leap. Your physical vessel is currently unstable. If you do not circulate this energy immediately, the internal pressure will detonate your own meridians. Do not move!]

Anne stepped forward, her face pale. She could feel a pressure emanating from him that made the hair on her neck stand up—a mortal danger she hadn’t felt in decades. It felt as if the air around Ethan had turned into a field of invisible blades.

"Ethan, breathe," she said, reaching out. "I’ll help you stabilize it. I can use my blood-threads to—"

"Stay back!" Ethan roared, his voice layered with a strange, metallic echo. "I can’t... I can’t control it yet! You’ll be hurt!"

"I’ll be fine," she countered, her pride as a Matriarch flaring.

As she took another step, a bolt of amethyst lightning—thick and jagged as a serpent—snapped away from Ethan’s aura. It lunged at her with predatory intent. Instinctively, Anne unleashed her Crimson Threads, hundreds of razor-thin lines of blood-red energy weaving a defensive web in a millisecond.

BOOM.

The collision shook the mountain to its roots. Anne was blasted back several meters, her heels digging deep furrows into the obsidian floor. She stared at Ethan, her heart hammering. Before this moment, she had viewed Ethan as a brilliant tactician and a formidable talent, but never a true peer in raw power. Now, everything had changed.

She had used ninety percent of her defensive output to negate that single, stray spark—and the lightning hadn’t even flickered. It had met her strength for strength. To her horror, she couldn’t sense Ethan’s fluctuations anymore. Either his power had surpassed her ability to read him, or he had become a void that swallowed all logic.

She tightened her stance, her Crimson Threads glowing with a lethal intensity. She was no longer looking at an ally; she was looking at a force that could potentially unmake her.

Ethan stood at the center of the vibrating nest, his silhouette flickering like a glitch in reality. The amethyst lightning that had nearly leveled the cavern began to pull inward, drawn not by his will, but by the gravitational pull of his own eyes. The violet radiance of his pupils grew deeper, darker, consuming the stray arcs of energy until the air ceased to hum.

Slowly, the sprawling black spiral that had claimed his entire arm began to recede. It slithered down his shoulder, past his elbow, and over his wrist like a retreating tide, finally settling as a singular, thick band of obsidian ink wrapped around the base of his right middle finger.

Ethan exhaled a long, jagged breath that came out as a plume of silver mist. When he opened his eyes, the predatory madness had faded, replaced by a terrifyingly sharp clarity. He looked up, noticing Anne for the first time since the surge. She was still in a combat stance, her Crimson Threads taut and shimmering with a lethal, defensive light.

"You can stand down, Anne," Ethan said, his voice sounding deeper, resonant with a weight that wasn’t there before. "The storm has passed."

Anne didn’t lower her guard immediately. Her eyes darted to the black ring on his finger, then back to his face. "Passed? Ethan, you nearly took the ceiling down with a stray spark. What in the hell did you just absorb? That wasn’t just mana. That was... something..."

Ethan didn’t answer. Instead, he looked down at the floor—the hardened, obsidian-like substance that Crul had identified as the secretions of a Nightmare Claw. He felt an instinctive, magnetic pull toward the ground. Guided by a sensation he couldn’t name, he knelt and pressed his palm flat against the cold, black surface.

"Ethan, don’t—"

But before she could finish, the cavern groaned. The floor beneath Ethan’s hand began to ripple. What had looked like solid rock for thousands of years suddenly liquefied, turning into a thick, viscous sludge that surged toward his palm. It wasn’t just melting; it was being devoured.

A massive vortex formed around his hand. The black secretions from every corner of the nest began to flow toward him like a river of ink, spiraling into the black ring on his finger. The sheer volume of material vanishing into his hand defied the laws of physics.

"It’s not stone," Anne whispered, her voice trembling with awe as she watched the nest literally vanish into Ethan’s body. "It’s biological energy... and you’re eating it."

"I’m not eating it," Ethan muttered, his eyes locked on the swirling vortex. "I’m reclaiming it. This belongs to me now."
