Magatsunokami! Ōkuninushi!

At that moment, Uchiha Genki was already completely submerged in the despair of losing his mother and sister to a cruel death.

His consciousness drifted through the darkness. His reason had long since collapsed, leaving only the most primal pain and resentment.

It was this overwhelming emotion, like a key, that stirred the terrifying ocular power sleeping within him.

Completely unconscious, his body instinctively unleashed two forbidden ocular techniques powerful enough to overturn the Shinobi World!

"Vmmmm—!!!"

A deep hum rang out across heaven and earth. Centered on Genki, a pitch-black domain spread instantly.

Wherever the domain passed, the air seemed to be sucked away. The already crimson night grew even thicker, and a bone-chilling cold replaced the biting night wind. Countless twisted underworld patterns flowed along its edges, as though the gates of Yomi were slowly opening.

This was Yomi Hell, belonging solely to Magatsunokami. In the blink of an eye, it enveloped the entire Uchiha Clan Compound!

The next second, a horrifying sight appeared. The souls of the Uchiha who had just been slain by Itachi Uchiha, not yet dissipated, seemed seized by an invisible hand. One after another, they let out shrill screams as their pale-blue spirit forms struggled violently, stretched, and twisted.

Their struggles were futile. In the end, they turned into streaks of light and were drawn inexorably into the depths of the Yomi Domain, becoming sustenance for the terrifying realm.

"What... what kind of ocular technique is this?!"

Not far away, Itachi Uchiha's pupils shrank to pinpoints. His crimson Mangekyō Sharingan spun rapidly, his eyes filled with incredulous horror.

He could clearly sense the terrifying power within that domain, a force capable of devouring souls. It was a forbidden power far beyond his understanding. Every hair on his body stood on end, and an intense, ominous foreboding coiled around his heart like a cold snake, making it hard to breathe.

He absolutely could not allow this power to spread any further!

"Amaterasu!"

Without the slightest hesitation, Itachi Uchiha roared.

The burning pain in his eyes from using his Mangekyō Sharingan techniques one after another felt like they were being seared by flames. The veins on his forehead bulged with pain, but he didn't even furrow his brow.

Pitch-black Amaterasu Fire burst from his eyes, carrying an extreme heat that could incinerate all things. Like a black serpent of flame, it surged madly toward Uchiha Genki.

But just as the Amaterasu Fire was about to touch Genki, a colossal black apparition suddenly burst from his body. It descended like a curtain of night, instantly shrouding him entirely.

Driven by the power of despair, the apparition took shape at a visible speed. It was a gigantic skeleton dozens of meters tall, its bones black as tempered iron and wreathed in thick black mist. Every joint radiated a suffocating pressure. Its mere presence made the surrounding space ripple.

"Sizzle—sizzle—"

The Amaterasu Fire slammed into the black skeleton with a harsh sizzling sound. The black flames licked wildly at its bones, yet could not penetrate the mist's defenses.

After a few moments, the blazing Amaterasu Fire gradually dimmed, as if its energy had been drained away, then went out completely.

Just then, Itachi Uchiha abruptly looked up, his gaze fixed on the sky. The horror on his face deepened. Countless pale-blue spirit forms were pouring out from every corner of the Uchiha Clan Compound.

Some still bore the terror they had felt before death, while others retained the ferocity of battle. But all had lost their free will. Like iron filings drawn to a magnet, they rushed toward Uchiha Genki!

They were the souls of the thousands of Uchiha he had personally slain!

The spirits gathered behind Genki, forming a vast sea of souls, so densely packed that it stretched beyond sight.

Their gazes were dull and vacant, the expressions stripped from their faces. Their memories and consciousness had clearly been devoured by Magatsunokami's power, leaving only empty husks to be manipulated at will.

"Aaaah—!!!"

The next second, a heart-rending scream burst from Uchiha Genki's throat. His voice was as hoarse as a cracked gong, filled with unbearable pain, and echoed wildly through the silent compound, raising goosebumps.

He clutched his head with both hands, his nails digging deep into his scalp. Blood ran between his fingers and down his cheeks.

The memories of thousands of Uchiha poured into his mind like floodwaters bursting through a dam!

The despairing cries of children as Kunai pierced their bodies; the stubborn resistance of old people fighting to protect their grandchildren; the resentment and bewilderment of clan members in their final moments; and the warmth of everyday life—the games at the mouth of the alley, laughter around the dinner table, his mother Hazuki's gentle reminders, his sister Izumi offering him candy...

These memories were more than simple images. They came with the most vivid sensations and emotions!

He could clearly feel the warmth of a child's body, the stickiness of an old person's blood, the chill of the clan members' resentment, and the fleeting comfort of those warm memories. But that warmth was instantly replaced by the pain of their gruesome deaths. Two extremes of emotion clashed violently in his mind, threatening to tear his consciousness apart!

"Get out—!! No—!! All of you, get out—!! Aaaah—!!!"

He screamed frantically. His body collapsed to the ground against his will, rolling and struggling like a wounded stray dog.

His limbs kicked wildly, gouging vicious scratches into the flagstones. A mournful whimper rose from his throat as tears mingled with blood and streamed from his eyes, pooling on the ground in a scarlet puddle.

Despair, pain, resentment, indignation... countless negative emotions coiled around his soul like poisonous vines, tearing it apart and crushing it bit by bit.

And yet he couldn't die. Once Ōkuninushi's power was unleashed, it could no longer be stopped!

The moment the souls gathered by Magatsunokami entered the domain, the simultaneously activated power of Ōkuninushi forcibly devoured them, sending an endless stream of them into his body.

Along with this unbearable pain came an immeasurably vast power!

The chakra of countless clan members surged wildly through his body like a rushing river;

Their rich spiritual energy continually nourished his shattered soul, yet made the pain all the more vivid;

And the Sharingan power of those clan members gathered like points of starlight, forming a terrifying torrent that surged through the meridians around his eyes!
