ITACHI'S MANGEKYO SHARINGAN

"Itachi..." Karl's voice brought him back to the present.

Itachi blinked, his Mangekyo Sharingan fading away as he refocused his gaze on Karl, "That was Tsukyomi, isn't it? So this is what was supposed to happen."

"Yes, that's what actually happened in the original timeline. And, no, it's just a cheap mimicry of the original," Karl replied, "Tsukyomi is your original Mangekyo Jutsu. Your right eye can summon black flames called Amaterasu. You can burn anything including fire itself and it won't extinguish unless the target is destroyed or you stop it. Master it as fast as you can."

Itachi nodded, his expression determined. "I will. But we need to focus on the task at hand—the rebellion. We don't have much time, and we can't let Obito's manipulation lead to tragedy."

"That's why you should be prepared. Now that his plan has been foiled, he won't stay still. He might just come after us and my condition isn't good. You need to be prepared to face him if the situation rises. That masked man specialty is Kamui, a dimension shift jutsu. He can ignore any attack and he can put you inside his own dimension. That's why, Itachi. You need to master it within one day. While I will focus on healing. Then we will move at tomorrow's sunrise," Karl explained.

Going against someone who has already mastered his visual prowess with newly awakened power might be a dangerous feat.

"Oh, and don't overuse it unless you want to go blind," He warned.

Itachi's gaze remained locked with Karl's. He had seen the potential devastation that could be wrought by Obito's manipulation and the Uchiha rebellion. Now, armed with the knowledge of the future and the path he needed to take, he strengthened his resolve to prevent that grim fate from becoming reality.

"Thank you, Karl, for entrusting me with this knowledge," Itachi said with a nod.

Suddenly, both of them stood up and looked outside the cave. They have sensed the ninjas surrounded their hideout.

"Well, looks like you are in luck," Karl said with a smile. "Perfect time to test your new powers. Go on, I will wait here." He felt a piercing pain in his chest. His broken ribs...

Itachi's gaze hardened, and his Mangekyo Sharingan once again flared to life. His body moved with a fluid grace as he stepped out of the cave, his presence exuding a sense of calm confidence.

The intruders, a group of masked ninjas, closed in on him with a barrage of shuriken and kunai. With a swift motion of his hand, Itachi activated his newly awakened power, "Amaterasu!" A swirling vortex of black flames erupted, incinerating the projectiles in their path.

Itachi's Mangekyo Sharingan glinted with a red glow as he moved, a force to be reckoned with. His movements were fluid, a dance of power and precision. The intruders lunged at him, their attacks relentless, but he was a storm of calculated grace.

Flames erupted from his eyes, a torrent of darkness that devoured the incoming projectiles. The shuriken and kunai were reduced to ash before they could even touch him. His control over the black flames was absolute, a manifestation of his newly awakened strength.

In response to their assault, he unleashed his counterattack.

"Tsukyomi!"

With a mere glance, his genjutsu prowess shattered their perception of reality.

Within the illusory realm of Tsukuyomi, time twisted and contorted. The ninjas found themselves trapped within their own worst nightmares—nightmares so vivid and horrifying that they felt as real as the world they knew. Their screams of agony echoed in the abyss of their minds as Itachi's power consumed them.

He took out his sword.

With a blade honed in shadows and power, Itachi moved with an unyielding purpose. His swift strikes met no resistance as his sword danced through the illusion-bound enemies, severing their connection to life. Each slash carried an intensity of purpose that spoke volumes beyond words.

Blood splattered as the intruders fell one after another. In mere seconds, he eliminated ten ninjas.

He unmasked the last one. He was a rat faced bastard. Itachi remembered him from his days of training. His was a fucking troll and a nifty ass licker, known for his cruel ways of dealing with the missions. Thanks to him, many ninjas lost their lives during mission. But surprisingly, all the missions he went were successful and he is the only one who returned alive without a single injury.

Due to his nature, he rose high in rank... Well, not that it did any good to him. Instead, it brought him to his impending death.

This bastards name is Chaddts. [-Fucking troll you just died.]

"Amaterasu!" Black flames engulfed the dead bodies and the last surviving ninja. Fucker died a painful death. Finally, the souls of the ones he killed will rest in peace.

As the last of the attackers crumbled into nothingness, Itachi's Mangekyo Sharingan faded away, leaving behind a lingering sense of dread in the air. The cave entrance stood silent once again, the battle's echoes replaced by a heavy stillness.

"Anbu! Danzo!" He clenched his fist as Shisui's smiling face appeared before his eyes just before he died.

He rubbed the blood that was dripping from the corner of his eye due to the usage of Amaterasu and looked around for potential threats. Then he set up a genjutsu to prevent any more intruders from attacking.

With the immediate threat eliminated, Itachi and Karl exchanged a brief but meaningful glance. Without a word, they knew it was time to leave their current hiding place. The cave had served its purpose, but it was now compromised.

In a matter of moments, they had packed their few belongings and vanished into the surrounding forest, their movements swift and silent. The leaves rustled underfoot as they navigated the terrain with practiced ease.

The forest canopy cast dappled shadows on the ground as they moved, their senses heightened, and their guard never faltering.

But Karl was having a hard time due to his broken ribs. But despite his discomfort, maintained a watchful eye on their path. His movements were slower than usual due to his injuries

They took small breaks in between, due to Karl's injuries. And finally at the end of the day, they reached a small broken hut in the middle of a marsh.

"A hut!" Karl muttered.

"A hidden escape route I made. It will directly lead us to my house," Itachi replied as he removed the genjutsu. There were approx ten to twenty seals around the area including paper bombs.

They carefully entered the broken hut and Itachi removed a carefully concealed hatch in the floor. Beneath it was a hidden underground passage that led to a network of tunnels. It was a well-planned escape route, designed for moments just like this.

They descended into the darkness, their footsteps echoing in the confined space. The air was damp, the scent of earth and moisture permeating the tunnels. The walls were lined with faintly glowing moss, casting an eerie luminescence that barely illuminated the path.

Navigating through the labyrinthine tunnels, they moved deeper underground.

After walking for an hour or so, Karl stopped, "Damn! You got some painkillers? Fuck! It hurts so much!" He groaned in pain as he slumped on the ground and leaned on the wall.

Itachi took out an emergency medicine pill, "This will help you with the pain. I will get a healer as soon as we reach my house."

"Yeah, taste like shit, but thanks," Karl swallowed the pill.

Itachi helped him up and put him on his back and dashed with full speed.
