As an Uchiha I became the Jinchuriki of Senju Tobirama

“Yes…”

“It’s right there, Rin, a little softer… Very good, you’re doing great, your technique is already very delicate…”

Kazuki gently instructed Rin who was learning the Mystical Palm Technique. As an A-rank ninjutsu, the learning difficulty of this technique is still too high for the students of the Ninja School.

After all, even most Jonin couldn't master this technique.

However, Rin did not let herself be defeated by this difficulty. Even though she was so nervous that there were beads of sweat on her nose, she still tried her best to follow Kazuki's instructions.

After a long time, the somewhat exhausted Rin sighed. "I still can't do it, Kazuki-kun."

Shisui on the side nodded slowly and encouraged: “Rin, don’t be discouraged. Geniuses like my brother are very rare, but you’re already doing very well.”

Kazuki waved his hand indifferently. "I am not a genius at all. I am just a few years older than you. At Rin's age, I can't even master the Transformation Technique..."

Shisui and Rin pouted in sync. By this point, no one believed that Kazuki had ever been a mediocre ninja.

“The Mystical Palm Technique has two key aspects: the creation of medical chakra and precise chakra control.”

Kazuki's fingers lit up with a little green fluorescence, and he explained: "The so-called medical chakra is to decompose chakra into small and soft fragments to heal injuries. Non-attribute chakra is a more moderate choice, and Yang Release chakra with a stimulating effect on the body is the best choice."

"So, the so-called medical ninjutsu practiced to a higher level can be regarded as the same as the secret technique of the Akimichi clan, which is a special use of Yang attribute chakra."

“As for precise chakra control, it’s a matter of constant practice. And Rin, you already have a lot of talent in this area. With daily practice, you will undoubtedly master it.”

Rin nodded nervously. "I will work hard, Kazuki-kun."

Rin valued this opportunity greatly. She learned from Kazuki knowledge that was not taught in Ninja School, and even details that her instructors would not be able to explain to her after graduation. She was grateful for the opportunity.

Kazuki looked at Rin, and an interesting idea came to his mind.

Could the Sharingan's 'copy' and 'hypnotize' abilities be combined to create an 'autopilot'-like effect, allowing a hypnotized ninja to perform ninjutsu they normally couldn't, and develop muscle memory?

This principle is a bit like teaching a child to ride a bicycle.

At the beginning, they still need to be supported to ride, but when the adults quietly let go, the children can still ride well. With the help of psychological suggestion and muscle memory, they have mastered this skill.

If Kazuki's conjecture is successful...

It could be a quick method to learn advanced ninjutsu! Master Kazuki, at your service. No ryo needed! You just need to have Kazuki's will of fire in your heart...

“Tobirama, how about I bet that I can make Rin master the Mystical Palm Technique today?”

Kazuki sought Tobirama's opinion.

After completing the written exam on the Will of Fire, the Second Hokage was a little nervous, eagerly awaiting his results. It could be seen that Tobirama was worried about the possibility of Kazuki getting a perfect score while he only managed 99 points.

“Boy don’t speak without thinking. If you can make a seven-year-old girl master an A-level jutsu, then Hiruzen no longer needs the position of headmaster of the Ninja School, you should take it instead!”

Tobirama waved his hand disdainfully. “Even if I taught her myself, I couldn’t guarantee that she would learn it in a week. Let alone you.”

Kazuki chuckled. “Let’s stick to the same rules as always. If I lose, I’ll do whatever you ask. If I win, you don’t have to bow down to me, I just ask that you guide me in my training from time to time.”

"If you want to worship me as your master, you might as well say it directly, although I won't agree." Tobirama smiled. It seemed like Kazuki was looking for any excuse to get him to teach him.

Curiously, Tobirama didn't feel any repulsion towards Kazuki. In fact, he felt somewhat pleased. Although his mouth kept saying that he wouldn't train him, his attitude said otherwise.

"Old man, you seem a bit narcissistic. I suggest you reflect on your will of fire." Kazuki ruthlessly criticized Tobirama, then turned to Rin and said hesitantly: “Rin, I have a rather bold idea. Perhaps it will help you quickly master the Mystical Palm Technique.”

"However, this requires you to trust me very much, and I cannot guarantee that it will succeed. Do you want to try?"

Rin blinked. Is there such a good thing?

"Please do it with confidence, Kazuki-kun. I don't mind even if there are risks..."

Kazuki nodded. “In that case, let’s go near the Hokage Residence and wait for Guy and his father there.”

“To fully master this technique, we need to practice in a real situation. In this way, we can also help Mr. Duy alleviate his ailments.”

“I have observed Mr. Duy from afar. Although his body is strong, he has many hidden ailments that could affect his career as a ninja.”

Rin nodded again and again.

If all went well, this would be the first patient she would treat in her life as a kunoichi, which would be an unforgettable memory.

...

"Father, I am a genius, a hard-working genius recognized by Kazuki-kun, who is more talented than Kakashi!"

“This is youth! My youth is burning thanks to the inspiration of my friend!”

Might Guy ran with boundless energy, as if he never ran out of strength.

At seven years old, his mind was still not as firm as it would be in a few years. After suffering a blow, he also questioned himself and felt that Might Duy's strange clothes were ridiculous.

But being told bluntly that he was a genius, and had even inspired him, by Kazuki, known as Konoha's greatest genius, only strengthened his resolve.

Might Duy, who was running behind him, looked at his son with satisfaction. At first, he encouraged him loudly, but then his steps began to slow down.

"Guy, you have found a very good friend. I am proud of you..." Might Duy placed his hand on his waist, where a sharp pain shot through him.

Years of malnutrition and grueling training had made this iron-willed man understand the sufferings of hidden injuries.

“Kazuki-kun! You’re training hard today too!”

Not far away, hearing his son's excited voice, Might Duy's eyes lit up. He suppressed the pain in his waist, showed his radiant smile and rushed forward.

Might Duy wanted to thank Kazuki, thank her for being the true inspiration for his son's youth.

"You're looking very cheerful today, Guy!" Kazuki responded to Guy's bright flash of teeth with the same gesture, giving him a thumbs up in approval.

Shisui and Rin blinked, turned their heads and exchanged glances, and both nodded tacitly: 'As expected of you, brother/Kazuki-kun, you are so handsome in any action!'

"Guy, I came to you today because I want you to help me with something." Kazuki patted Might Guy's shoulder. "You know, I have been practicing medical ninjutsu recently and have some experience. If possible, please allow me to check your body and your father's body."

"After all, the body burning with youth is more valuable for research. Please forgive me for being presumptuous, Guy..."

Kazuki skillfully changed the language system to the youth form but Might Guy's expression gradually became serious.

Although Might Guy constantly spoke of youth, even in the exams he could discourse on youth in front of Hiruzen and the Will of Fire.

But he was not a fool. He had the intuition of a beast and could distinguish between good and evil in people.

However, what this young beast saw was only Kazuki's sincere and pure heart.

"Kazuki-kun, my lifelong opponent, how can you let me repay this favor!"

Guy clearly remembered that after a duel with Kazuki that left him exhausted, the Mystical Palm Technique had relieved his tired muscles in such an incredible way that the fatigue disappeared almost instantly.

And when Guy came home excitedly to tell his father about this, he learned that it was an A-rank ninjutsu that not even many jonin could master, and even in all of Konoha only a few knew about it.

And the few who knew this technique, were not someone Guy's family could approach.

"What are you talking about, Guy? There is no debt to pay…" Kazuki smiled as he patted him on the shoulder and said softly: "This is the will of fire and youth. You help me, I help you, right?"

Might Guy clenched his fists, and tears flowed like a stream.

Kazuki looked at him curiously. The Might family's tears seemed to flow down in a waterfall. Could this be some kind of special Kekkei Genkai?

At that moment, an even more robust man in a tight green suit ran towards them, sobbing, and hugged Guy, even trying to include Kazuki in the hug to cry together.
