Naruto: Transmigrated in Avatar World

Chapter-1

Had we come to this?

To fight to the death against someone I considered my first friend?

Why did everything have to end so badly?

This mission was meant to rescue Sasuke, taken by four Sound Ninjas. But in every effort to save him, we lost our comrades one by one: Choji, Neji, Kiba, Shikamaru, and finally Lee. They risked everything for a fellow Konoha ninja. If only they knew that the Uchiha we were trying to save had willingly gone to Orochimaru.

He faintly recalled the battlefield they were in now. If his memory served him right, it was the Valley of the End. This place was famous for a battle that occurred ages ago, a clash between two of history's mightiest and most rivalrous ninjas. The irony wasn't lost on him; history seemed to be echoing its past once again. If only his last name happened to be Senju, this situation could easily be mistaken for a poorly-made imitation of that epic showdown.

Right now we were wrapped in the cloak of a Kyubi tail fighting Sasuke who had the second phase of the cursed seal activated giving him a grotesque appearance, were we really going to clash our most powerful attacks like this? 

I could see Sasuke's eyes, so much hate and resentment, the… was he really trying to kill me?

"Naruto!"

My reaction was one of disbelief as I witnessed his intent to launch that lethal assault directly at my heart. 

Why did he not seem hesitant to execute the attack? 

Now I realized if I doesn't defend myself now then I would surely be dead.

"Sasuke!"

With all my might, I screamed, extending my right arm to point my Rasengan directly at the head of the person I had once considered my brother... oh, how foolish I was.

When our attacks collided, I observed the formation of a cancellation reaction, generating a strange, dark sphere around us. Without hesitation, Sasuke lunged at me with a punch.

In that instant, time seemed to slow down. A voice inside me urged me to use the claws that the Kyubi had bestowed upon me — to drive them into Sasuke's chest. I knew what I had to do; I needed to stop him. The realization hit me: Sasuke's alignment with Orochimaru meant that he would eventually set his course against the village, against all his friends and acquaintances. I had to intervene to prevent him from causing harm in the future; it was an imperative.

My arm extended, fingers turned into claws, I raked straight at Sasuke, who struggled to react. Mere inches from dealing the decisive blow, I couldn't help but think, "I'm so foolish..." And then, lifting my arm, I tore at Sasuke's headband. The next sensation I felt was that traitor's strike to my stomach. Suddenly, a blinding white light engulfed everything around me. Gradually, I witnessed Sasuke fading into the brilliance while I plummeted.

How could he take the life of someone he once held as a friend?

…..

Tenzo Hazumo was only an old man of 126 years, he worked as a doctor in a small town on the borders of the earth kingdom that was now occupied by several squads of the fire nation, his appearance was ordinary, he was bald and had a long beard with mustache that reached to his chest, he wore the typical green and brown clothes of the inhabitants of the earth kingdom.

Right now he was walking along a path carrying several branches on his back and holding on to his trusty wooden cane. In his life he has seen many things and done many, such as seeing the Northern water tribe with his own eyes, climbing the mountains to to see the flying bison of the air nomads, to see dragons in the famed lands of the fire kingdom, to have a threesome with two beautiful women from the water tribe, if those were precious memories that he would not forget, unless his case of senility increased . If it was a long life with many experiences, nothing could surprise him anymore.

Except seeing how now the sky was opening up showing a strong white glow followed by a strong explosion that knocked him down. In the midst of the chaos, the old man saw a silhouette in the light fall into the middle of the crater where the explosion was formed, once all the way Tenzo came closer to see what caused all this disaster and his surprise was great when he met a brat.

Using his cane he pokes his ribs…

"Ahgggg" 

Hearing the groan, a sigh of relief scaped from the old man's mouth. 

Because it meant that young boy was alive, that was good, bending down he took it to put it on his shoulder, using his cane he went home at a slow pace carrying the snot on his shoulder.

….

Three broken ribs, muscles atrophied in both his right arm and one of his legs, a rather severe head wound, and perhaps most concerning of all, a peculiar wound in the middle of his chest that resembled the result of being impaled by an unusual, hand-sized weapon.

However, setting these worries aside, what baffled him even more was how all these injuries managed to heal in a mere three days. 

Just three days.

It was utterly unbelievable considering that an ordinary person would require months to recover from such extensive damage. As Tenzo rifled through the boy's attire, he stumbled upon an array of weapons reminiscent of a pirate's arsenal—blades and star-shaped projectiles designed for throwing.

The question that echoed in his mind was: Who was this boy?

Determined to unravel this mystery, Tenzo sat beside the bed where the boy lay recuperating. His gaze traveled methodically from head to toe, taking in the numerous injuries the boy had sustained. Although the boy's hair and eyes were visible, Tenzo couldn't help but note their uniqueness. For the first time in his life, he encountered someone with this particular hair type.

Tenzo just looked at the unconscious boy on the stretcher, taking his cane he approached him, it was time to wake him up in a quick and subtle way.
