As an Uchiha I became the Jinchuriki of Senju Tobirama

After a while of displays of youth between father and son, Might Duy introduced himself to Kazuki.

"Guy, Dad is very happy that you have found a lifelong rival and a youth companion! Kazuki-kun, allow me to introduce myself, I am Guy's father, the crazy Duy of Konoha!"

Kazuki nodded seriously and extended his hand to him. "Nice to meet you, Mr. Duy."

The hands clasped together, and a strange spark appeared in Duy's eyes. He beat his chest hard, as if he had forgotten the pain in his waist, and exclaimed loudly: "Kazuki-kun, you can do anything to my body, please don't hesitate!"

"Uh... That's not necessary, don't worry, Mr. Duy, it's just a simple physical examination."

Although Kazuki was a little bit overwhelmed, he kept a smile on his face and motioned Might Duy, Might Guy and him to go.

At this moment, Kazuki also sensed a hidden chakra, locking his position from the direction of the Hokage Residence not far away.

"Telescope technique? Very good, I came to the Hokage Residence on purpose to attract your attention."

A spark of satisfaction fleetingly crossed Kazuki's eyes as the group arrived at a grassy field, Hiruzen's chakra following closely behind them, not missing a detail.

"Lie down, Mr. Duy."

"Oh! Got it, Kazuki-kun!" Might Duy nodded and lay down on the soft grass obediently.

"Please, I ask you not to make noise during what is coming."

The magatama in Kazuki's eyes slowly turned, and in front of Nohara Rin, Might Guy, and the peeping Sarutobi Hiruzen, he opened the double tomoe Sharingan.

Nohara Rin and Might Guy looked at Kazuki in shock.

In the Hokage Residence, the Third Hokage frowned, but then shook his head and said to himself: "Sharingan... That's right, with Kazuki's talent and his feelings for the village and his companions, it would be strange if he didn't awaken the Sharingan."

"But why show the Sharingan at this time?"

Sarutobi Hiruzen became curious, and even chose not to deal with the government affairs on the table for the time being and looked at it attentively.

Shisui frowned slightly, but still controlled his expression well.

"Sharingan has the ability to observe the flow of chakra... This is very effective for treating hidden injuries with medical ninjutsu."

Kazuki stared at Might Duy's sturdy body and couldn't help but admire it secretly.

He was a clear example of how to make the most of limited talent.

Although Might Duy's body does not look particularly strong, every muscle is full of traces of training and contains extremely amazing power.

Especially the meridians in his body, each of which is extremely thick and resilient, several times that of an ordinary person.

However, that strength was in contrast to the numerous hidden injuries on his body.

Deep bruises embedded in the muscles, small cracks in the organs from overexertion, displaced and aged bones...

Without proper nutrition, timely recovery after training, and the use of medication, even the most hardened steel would eventually show cracks after being repeatedly forged day after day.

Kazuki sighed from the bottom of his heart, with a hint of admiration in his eyes, and shook his head.

"Ah..." As if responding to Kazuki's expression, Might Duy covered his waist in pain and groaned in a low voice.

If it weren't for Kazuki offering his help, Might Duy might have endured the pain in front of his son, but knowing that there was hope for healing, he finally relaxed.

"Kazuki, is my father okay?"

Might Guy first looked at Kazuki, who was full of emotion and regret, and then looked at his father who was fine just now but now groaning, his face full of fear.

"The matter with your father, well, it's not simple, it's a bit complicated..."

Kazuki pondered until he heard... [From the target Might Guy, you gain a small boost to muscle strength!]

Finally, he smiled and replied confidently: "But it doesn't matter, as long as I am here, there will be no problem."

Might Guy exhaled a long breath and shook Kazuki's hand gratefully.

"Kazuki, thanks to you!"

"Rin, next, it's your turn." Kazuki turned his head and looked at Nohara Rin. "Are you ready?"

Rin looked into Kazuki's bright scarlet eyes. Although she didn't know what Kazuki was planning to do, she felt a slight tension within her. Still, she smiled and nodded. "I'm ready, Kazuki-kun."

"Very well…" Kazuki nodded, and his ocular power invaded Rin's body.

At this moment, the pattern of the Sharingan also appeared in Nohara Rin's eyes.

Immersed in the genjutsu, Rin was shocked to find that her vision had synchronized with Kazuki's. Even the sensation of manipulating chakra while using the Mystical Palm Technique was as clear as if she were performing it herself.

Shisui's talent for genjutsu, placed in Kazuki's hands, made Rin's experience incredibly real.

Nohara Rin, who was concentrating on her work, didn't realize that when Kazuki carefully cleared the pain in Might Duy's body, her hands slowly lit up with green fluorescence.

Although the glow was faint, it was unmistakable: she was using the Mystical Palm Technique.

Seeing this scene, Sarutobi Hiruzen unconsciously took out his pipe, lit it, and slowly exhaled a puff of smoke. "Good boy!"

"This pair of eyes that frightened the world turned into kind eyes in Kazuki's hands... Kagami, perhaps, there will be an Uchiha who surpasses you..."

Looking at the excellent offspring of his friend, Sarutobi Hiruzen sighed and thought of his rebellious little son.

Not even a firm hand could educate him; on the contrary, it only strengthened Asuma's rebellion, who not only refused to recognize his mistakes, but even threatened to run away from home, far away from the 'hypocritical Hokage and Konoha'.

"Ah... Asuma, Asuma, why can't you learn from Kazuki?" Thinking of this, a glimmer of light flashed in Sarutobi Hiruzen's eyes. "It seems to be a good idea, let me think about it..."

At the same time.

Senju Tobirama watched Kazuki's operation silently.

What did he see?

The evil Sharingan of the Uchiha clan has become a teaching tool, allowing a seven-year-old ninja school student to learn A-rank ninjutsu.

Senju Tobirama, who has made a bet with Kazuki, does not intend to default.

Although not abiding by the agreement will not burden Senju Tobirama's mentality, but facing Kazuki, he does not want to do so from the bottom of his heart.

"It's nothing more than teaching this kid a few ordinary ninjutsu. After all, breaking one's promise is not in line with the will of fire... Well, that's it..."

Senju Tobirama said this to himself, but a smile unconsciously appeared on the corner of his mouth.

[From the target Senju Tobirama, you get Fire Release: Great Fire Annihilation!]

The strange reward arrived, but Kazuki didn't pay attention to it. Instead, he repaired Might Duy's body very seriously. Even though fine beads of sweat oozed out of the tip of his nose, the chakra in his palm was as stable as at the beginning.

A man who works so hard deserves Kazuki's respect and is worth spending time on.

Might Guy nervously watched Kazuki treat his father, his mouth was dry, and he didn't even dare to breathe.

Rin, immersed in the world of genjutsu, seriously watched the way Kazuki handled the Mystical Palm Technique.

Shisui looked at Kazuki with admiration. At this moment, he only felt that his brother was the one who understood the will of fire the most in Konoha!

And Might Duy, for his part, seemed to be floating on a cloud.

The pain that he could only bear with willpower in the past was removed from the root by Kazuki, making this iron man fall into a deep sleep, even snoring.

After a long time, Kazuki nodded and wiped his sweat: "Success..."

Might Guy immediately came over nervously. "Kazuki, is my father okay?"

Before Kazuki answered, Might Duy suddenly jumped up from the ground, turned 720 degrees in the air, and landed in an extremely abstract and difficult posture, with tears streaming down his face. "My body has rekindled the youth of a boy!"

"Such a strong and powerful youth!!"

Might Duy enjoyed his body as if he had been reborn. The relief that came from the elimination of these persistent illnesses that had afflicted him for decades was simply indescribable for a ninja who practices taijutsu.

"Mr. Duy, you will have to come for regular check-ups in the future. Intensive training will not be a problem, but you must also take care of your recovery…"

Kazuki watched Might Duy jump back and forth with a smile and spoke to him in a gentle tone.

Might Duy stopped in his tracks. As an adult, how could he not understand what Kazuki was implying?

But when he turned around, Kazuki was already tending to Might Guy. "Your body is in good shape, Guy. If there's any problem, come see me."

Might Duy was feeling a mix of emotions. He didn't like owing others favors, but Kazuki's selfless generosity made him wonder how he could return the favor.
