As an Uchiha I became the Jinchuriki of Senju Tobirama

"My body is still too weak... Although a ninja has enough strength to move mountains, he is still vulnerable to conventional weapons."

"If this shortcoming can be made up, safety will be greatly improved, and it will be of great benefit to the battle."

While Kakashi was relieving his sore arms, Kazuki was also reflecting on this battle.

At that moment, an electronic voice resonated in Kazuki's mind.

[Detected a strong desire to win in Hatake Kakashi towards the host. Target linked.]

Kazuki's eyes lit up.

Kakashi's desire to win seemed to be stronger than he thought.

"Kakashi, it seems I can't hold back anymore..."

Kazuki's eyes changed, and the Muramasa in his hand burned with a raging fire.

Kakashi's eyes narrowed as a sense of danger washed over him.

"Earth Release: Earth-Style Wall!"

The towering earth wall stood in front of Kakashi, giving him a little sense of security.

"Wow... this chakra level is quite impressive."

Kazuki looked up at the towering earth wall. As a seven-year-old ninja, this is definitely not something that a ninja with insufficient chakra can release.

"But, it's useless, Kakashi..."

Kazuki swung his Muramasa sword. The flames on the sword transformed into a fire dragon that charged at the wall, melting it with its intense heat.

"Tsk, flashy, this kid still learned the swordsmanship of that bastard."

Senju Tobirama curled his lips.

Kakashi on the other hand, watching his wall melt in the flames, was left speechless.

And then Kazuki fell from the sky, engulfed in fire, and cut it down with a deadpan attitude!

But at that moment, a blue chakra slash shot out from the side, colliding with Muramasa.

[Boom!]

Suddenly, the dust covered the training ground.

Kazuki narrowed his eyes, feeling the numbness in his hands, and looked at Sakumo, who had an apologetic expression on his face.

At this moment, Kazuki finally saw Hatake Sakumo's fighting style!

Kakashi was stunned on the ground, looking at Kazuki who was still calm, and finally realized the gap between them...

[From the target Hatake Kakashi: You gain the Lightning Chakra attribute!]

[From Uchiha Madara's target: You gain the Fire Release Ninjutsu!]

Kazuki had gotten the rewards he expected, albeit with an added surprise. He sighed deeply, looking around, but found nothing strange.

No, why is there an old man peeping?

That's enough, do you understand what distance is!

...

Mountains' Graveyard.

Uchiha Madara was half reclining on a wide chair, his mind filled with the image of Kazuki holding the Muramasa sword. The sharp blade and the flames that filled the sky, along with that sword technique and cold gaze...

That stance, in the entire shinobi world, was only matched by that of his brother, Uchiha Izuna.

Especially the way Kazuki used the Muramasa sword, and the Fire Release techniques were identical to Izuna's. Even Madara had the feeling of having traveled back in time, of having returned decades ago, to the moment when his brother was enthusiastically showing him his kenjutsu…

"Izuna, Izuna..."

Uchiha Madara recalled his younger brother, the best younger brother.

Uchiha Izuna's life, thinking back carefully, is a life dedicated to Uchiha Madara.

As a child, Izuna was his spiritual pillar, and as he grew up, he became his advisor and support in combat. He never left any offspring, and in the end, he voluntarily chose to gift Madara his Mangekyo Sharingan, dying in his prime.

Even though Madara was an unparalleled genius, and ruled the shinobi world as the feared Shura of the shinobi world...

But for his younger brother, Uchiha Madara owed nothing but debt.

As a traditional Uchiha older brother who failed to protect his beloved younger brother, and was constantly cared for by him, Madara felt unspeakable guilt towards Izuna.

In a trance, Uchiha Madara suddenly thought of a possibility that made his heart tighten. Why did Kazuki know Izuna's kenjutsu?

Madara had taken almost all of Izuna's techniques and belongings with him when he left the village.

He only left the Muramasa sword, which Izuna had personally gifted to a close friend. So Madara decided not to take it.

But somehow, that sword was now in the hands of Kazuki, who had, in addition, somehow mastered Izuna's kenjutsu…

So, could it be possible that Kazuki is the reincarnation of Izuna?

After all, the Pure Land is real, and the souls of the dead have not perished, and the Impure World Reincarnation Technique has proved this!

Thinking of this, Madara began to tremble and slowly closed his eyes.

He was thinking.

Thinking about how to contact Kazuki, and even more thinking about whether his plan needed to be changed...

But no matter what, the figures of Kazuki and Izuna were intertwined and flashing in Uchiha Madara's mind, as if they had merged into one.

"Ah..."

A sigh, a mixture of emotion and heaviness, echoed in the cave for a long time.

...

On the training ground.

Kakashi was lying on the ground, staring in shock at the Muramasa, engulfed in flames, and at Kazuki, frowning.

He had imagined many times what it would be like to face Kazuki, but he never thought that he had already reached the level to stop his father's attack.

"Is this… is this the real genius?"

Kakashi clenched his fists tightly, remembering with shame the title of Konoha's First Genius that he had enjoyed for several years.

Sakumo narrowed his eyes, watching Kazuki intently, as he thought: 'This young man is amazing… I can't see through him.'

But Kazuki was in no mood to care about Sakumo and his son at this moment.

The strongest and most ruthless old man in the shinobi world just exploded a wave of large gold coins in a very heroic manner, and directly rewarded Kazuki with a full set of Fire Release ninjutsu.

This force is comparable to the first gold coin explosion that Kazuki obtained from Tobirama using the system information gap.

"Bah, if he wants to look, let him look a little. Crazy old man..."

Kazuki sighed resignedly in his heart, after all, the man had paid, gifting him a complete set of Fire Release ninjutsu.

As for blacklisting Uchiha Madara's viewing rights, Kazuki can't do it for the time being. Who told him to have the Demonic Statue of the Outer Path and the White Zetsu?

Since he can't resist, he can only choose to enjoy it...

However, Kazuki didn't know at this time that Uchiha Madara had already started his fantasy time.

"Kazuki-kun, I'm sorry."

Hatake Sakumo walked over slowly, with sincere apology in his eyes.

In order to protect his son, he had attacked more seriously than necessary, even launching a sword technique of great destructive power.

In theory, a ninja of his level should not have used so much force to supervise a simple practice between two children.

But the problem is that Hatake Sakumo also underestimated Kazuki's strength. He didn't expect him to be so fierce...

"It's okay, Sakumo-san, I also forgot that Kakashi is still a child..."

Kazuki glanced at Kakashi with a smile, turned to Hatake Sakumo and said: "Is that move just now the secret technique of the Hatake clan? It's really an amazing slash."

Hatake Sakumo nodded. "It is a technique that involves releasing invisible chakra through the movement of the sword, inherited from the ancestors of the Hatake Clan and from my own understanding as a ninja. It is my own creation."

"Awesome..." Kazuki looked at the shining sword, the White Fang, in Sakumo's hands, and said softly: "Sakumo-san, I rarely get the chance to face a sword master like you. Since I have the honor today, could you teach me a few moves?"

Kakashi raised his head suddenly when he heard it. He was already very upset when Kazuki said that he was still a child.

And now, Kazuki seems to want to challenge his father!

"Hey, Uchiha Kazuki, you are still a student who has not graduated from the ninja school..." Kakashi was about to refute Kazuki, but as soon as he said the beginning of the words, he became more and more unconfident.

So what if you haven't graduated from the ninja school?

Even if you are a special jonin, can you withstand Hatake Sakumo's slash?

Hatake Sakumo hesitated for a moment, then took a serious look at the Muramasa in Kazuki's hand, then smiled and nodded. "I am also very interested in your swordsmanship Kazuki..."

"Then, let's just exchange a few moves."

"Kakashi-kun, please move aside, the fight may be a bit intense."

Kakashi, still sitting on the ground, stood there stunned, looking at his father, who was also motioning for him to get up. He reluctantly walked away to the edge of the training field, watching the two fighters intently…

"Then, let's get started, Sakumo-san."

Kazuki raised his Muramasa sword and took a deep breath.

The Sharingan behind Kazuki's water film spun rapidly.

The Muramasa sword he held in his hands also burst into even more intense flames.

Suddenly, in the blink of an eye, Muramasa's sharp blade, wrapped in fire, swooped down on Sakumo from a strange angle.

"So fast!"

Kakashi was shocked. Even though he had tried his best to observe the battle, Kazuki's speed had exceeded his imagination. He could only see the afterimage!

Kakashi's eyes widened, his eyes full of unwillingness.
