Naruto: Sasuke Uchiha Returns from Soul Society

But to outsiders, such as the two sitting on the roof beams of the main hall, Sasuke and Itachi Uchiha were just standing there blankly, motionless.

"..."

The man wearing the orange spiral mask, along with the half-black, half-white pitcher plant beside him, silently gazed down.

"What are they doing?" Bai Jue asked curiously. "They're not fighting, and they're not exchanging words. Are they having a contest to see who can hold their breath longer?"

"It's a battle of genjutsu." Beneath the mask, Obito Uchiha's voice was deep and hoarse.

"The Sharingan is a dojutsu that excels at genjutsu. When two powerful users meet, the battle is no longer limited to the physical body, but unfolds in the spiritual world, where a more dangerous struggle takes place."

"That technique called Tsukuyomi?" Black Zetsu's voice hissed as he stared at Itachi Uchiha's eyes below, which were beginning to change.

Obito Uchiha did not answer immediately, but simply watched in silence.

A few minutes later.

The chakra within the two surged, sending dust flying from the ground.

Sasuke raised his head, holding the sword in one hand, upright in front of his chest.

Uchiha Itachi's body trembled violently, and he raised his right hand to cover his left eye tightly. A trickle of bright red blood flowed down between his fingers.

"...You're really something, Sasuke."

Itachi's voice was hoarse as he said in surprise, "You actually broke my Tsukuyomi."

"It's just a little illusion trick; no matter how you use those eyes..."

Sasuke spoke with disdain, his Mangekyou Sharingan bursting forth with intense light, "An illusion can never become reality."

Having said that, he formed a hand seal with one hand and held it upright in front of his chest, causing a dramatic change in his aura.

A jet-black flame rose from beneath his feet, engulfing his entire body.

"Um?!"

Obito Uchiha, perched on the roof beam, looked horrified. He sensed an extremely dangerous aura emanating from that presence.

"What is this?!" Bai Jue exclaimed in surprise.

Under their horrified gazes, Sasuke's form was undergoing a bizarre transformation within the pitch-black flames.

The color drained from his skin rapidly, turning as pale as a corpse. His already long black hair grew wildly, fluttering even without wind against the backdrop of the black flames.

Immediately afterwards, a layer of pale, bone-like substance emerged menacingly from his right cheek, spreading rapidly and eventually coalescing into half a mask with an ominous beauty.

The mask's eye sockets were pitch black, unfathomable.

Only in the depths of that empty space, the golden six-pointed star-shaped eyes of a beast, ravenous and mad, slowly turned, revealing a hint of sinister ferocity.

It formed an eerie contrast with his exposed kaleidoscope-like left eye.

A powerful and overwhelming aura surged from his body.

The dust on the floor of the main hall was blown away, and even the two figures hidden in the shadows above felt a strange sense of unease.

"I am not the same person I used to be, Itachi."

Sasuke's voice came from beneath the half-pale mask, hoarse, low, yet eerily calm.

"You actually mastered this power..." Itachi Uchiha looked at his unfamiliar younger brother, his eyes showing seriousness. "I really didn't expect that."

Sasuke gave him no more time to think. The ground beneath his feet suddenly collapsed, creating a large crater, and he transformed into a streak of black light and shot out.

This time it's not an illusion!

It was a real, hard-fought battle.

On Indra's blade, black flames extended as if they had come alive, drawing an irregular, pitch-black arc straight towards Itachi's neck.

Itachi Uchiha reacted quickly, barely dodging the attack by sidestepping.

But Sasuke's attacks did not stop.

The blade missed its mark, but the wrist had already flipped, changing the horizontal slash into a downward chop, the momentum of the blade increasing rather than decreasing.

Uchiha Itachi dared not be careless, raising the two kunai in his hands to block the trajectory of the falling blade.

"Clang!"

The clang of metal on metal illuminated Itachi's astonished face with the sparks that flew out.

He felt an extremely powerful force coming from the point of impact, and his tiger's mouth was instantly cracked, spurting out streams of blood.

He slid backward several meters uncontrollably.

The transformation into Hollowfication and the Shikai brought Sasuke far more than just a change in energy patterns; they also brought a geometric increase in strength, speed, and even reaction ability.

Itachi's heart sank, and he couldn't help but marvel at the sheer power of it...

But before he could regain his footing, a whip kick accompanied by the sound of air being cut swept across him.

"boom!"

A muffled thud.

Itachi only had time to cross his arms in front of his chest to block before he was blasted away again by the immense force, crashing heavily into the wall behind the main hall, kicking up clouds of dust.

"cough......"

The weasel slid down from the cracked wall, knelt on one knee, and a trickle of blood escaped from the corner of its mouth.

He knew that if Sasuke hadn't deliberately held back a bit of his strength just now, his chest, which had been hit, would probably have collapsed by now.

Sasuke doesn't seem to want this battle to end so quickly...

This realization made Itachi's gaze grow even more serious.

"Fire Release: Great Fireball Technique!"

Itachi stopped engaging in pointless close-quarters combat. He quickly formed hand seals in front of his chest, and a huge fireball roared out, instantly illuminating the dim main hall.

But Sasuke is faster.

They also used the same type of technique.

"Hado No. 33, Azure Fire Falls".

A fireball, larger than a giant fireball and with a bluish-white color, sizzled and swirled.

The two flames collided violently in mid-air, almost without any stalemate.

Itachi's Fireball Jutsu was instantly destroyed by the more "textured" Azure Firefall.

The still-burning blue-white flames continued to roar towards Itachi.

"It's not over yet."

Itachi's eyes were cold, and he let out a low growl as chakra surged in his right eye.

"——Amaterasu!"

Dark flames appeared within the "Azure Flame Fall".

This flame was neither powerful nor intense, but it was of a higher "level." Even the Azure Flame Pendant, which carried spiritual pressure, was burned by it, albeit more slowly.

"..."

On the roof beam, Obito stared in horror at the technique Sasuke had unleashed.

"What kind of magic is this brat using?"

"I don't know." Black Zetsu's voice hissed. He had been active in the ninja world for so many years and had never seen such a technique before.

Obito remained silent. So, where exactly does this power originate?

Below, the battle situation changes again.

As Sasuke watched his "Azure Flame Fall" about to be completely engulfed by Amaterasu's black flames, there was no surprise on his face.

His figure swayed slightly as he activated Instant Step and drifted backward.

The black flames followed it like a shadow, moving with Itachi's gaze and biting Sasuke tightly.

Itachi's gaze remained relentless, but even with the Sharingan's reputation for "insight," he couldn't keep up with Sasuke's speed.

Amaterasu's black flames grazed past Sasuke's afterimage and landed around the main hall, instantly igniting a ring of black flames and turning this shrine, which had carried the history of the Uchiha for hundreds of years, into a sea of ​​fire.

Sasuke frowned slightly as he looked at the burning beams.

He didn't want the place to be damaged too much.

He raised his left hand, and the six-pointed star kaleidoscope slowly rotated in the firelight.

Immediately afterwards, the buildings that had been engulfed by flames quickly returned to their original appearance.

Obito Uchiha above was filled with shock. What kind of ability was this?

Should we turn back time, or...?

But if I had to say, he could have done the same with Izanagi, but Sasuke's eyes were clear and he didn't look like he had lost his sight.

At the same time, the leaping black flames below had already closed in on Sasuke.

Sasuke's expression remained indifferent as he raised his right hand, which was enveloped in black flames, and gently grasped it.

The flame, which was said to never go out, vanished in an instant, like a candle flame that had been extinguished.

"Is this all the power of your Kaleidoscope?"

Sasuke lowered his hand, his voice full of sarcasm, "So it seems your capacity is nothing special after all."

Looking at his familiar younger brother, Itachi Uchiha actually showed a relieved smile.

"...You've really grown, Sasuke."

"Don't lecture me like an older brother."

Sasuke's voice turned cold, "You are not worthy now."

He raised his eyes, and in those heterochromatic pupils was pure killing intent.

"If this is all you've got, then this farce should end."

“I will send you here now, so you can go to the Pure Land to apologize to your father and mother.”

These words deepened the smile in Itachi's eyes.
