Naruto: Transmigrated as an Uchiha

The next morning, Mei cleaned herself up, put on the Uchiha-police-specific chunin ninja vest, and got ready for work. 

"Wait a minute, Neesan, can you bring back some books on human musculature and medical treatment when you come back?" he asked here before she could leave. 

"It's okay to learn new things. But Toshiro, you also need to make more friends." As a four-year-old child, it is not surprising that Toshiro is so eager to learn and has a thirst for knowledge.

After two months of continuous contact, she noticed a change in her sister's child. He stands out from his peers with his remarkable maturity and precociousness. It's not very common to see children displaying enthusiasm, determination, and self-control. She was happy that he had all of them but also concerned about Toshiro's social growth. She wished he could make more friends and have more opportunities to interact and play with kids his age.

He frowned. He didn't want to play with those little kids. But seeing Mei's insistent expression, he nodded again and agreed, joking later. 

"Then it's a promise! A man has to keep his promises."

"Hmm!" Confirming that Toshiro was not perfunctory, she smiled knowingly.

"The things that you asked for, I will bring them after three days." Saying this, she left for work. 

After watching Mei move out, Toshiro returned to the study and pulled out a thick book from the shelf; the title read 'Chakra Theory', and in the lower right corner of the book was the name of the author, 'Senju Tobirama'. 

Though this was written by one of the Senju, the most hated clan by the Uchiha, even the proudest of the Uchihas understood that Senju Tobirama is the pioneer when it comes to anyting chakra. The amount of jutsus he created, that too, which were non-elemental and forbidden ones, was more than anyone has on their own. I read 'chakra theory' and the 'History of Uchiha' books to pass the time. 

This is the first time he has taken something so seriously in his life, including the previous one. In his mind, he wanted to understand the most important factor in becoming a ninja, i.e., chakra. It is very essential for his livelihood in this world. Sitting on the veranda outside the house, Toshiro holds a book in his hand, sometimes reading carefully, sometimes looking up, looking at the flowing clouds in the sky, and occasionally enjoying the scenery in the courtyard. 

'Well! This way of life isn't so bad after all. Even though progress is a little harder, my thoughts inevitably turned to the impending Third Ninja World War and the Nine-Tails Incident. The Uchiha extermination tragedy occurred after the Nine-Tails incident. Pain's complete obliteration of Konoha. There are also main bosses hidden behind the scenes, such as Uchiha Obito, Uchiha Madara, Black Zetsu, etc.'

Obito should be a small child at this point; perhaps I can kill him before he becomes a problem... Argh!! Forget it; if it's not Obito, then it will be Obisu or someone else. I am a similar age to Obito; it might even be me. What if Madara targets him? What can he do? Just thinking of the old, wrinkled face of Madara gave me chills.

'Knowing too much is sometimes not a good thing.' Otherwise, it's not a bad thing to be an ordinary ninja. I read the book for almost two hours. Put away the book. He strode towards the empty dojo on the left side of the house. It has complete, solid wooden flooring. In the middle hangs a sandbag. This place is very suitable for a child of his age to practice physical Taijutsu. It might be that even my father has trained here.

"Ha" with a loud shout. A bandaged fist slammed into the sandbag with a crisp snap. The sandbag just shook slightly. Following the first punch, the second, third, and fourth punches hit the sandbag one after the other. Then I combined knee strikes, kicks, and other techniques. Even though, as a four-year-old, I do not have too much force in my strikes, each attack is extremely serious and in proper form. Jabs, straights, hooks, kicks, and flying kicks are all in accordance with the form taught by the trainers in the training camp.

Although I have no experience in martial arts, there was this cliched saying in my previous life: 'The journey of a thousand steps starts with one,' and for the glory I want to achieve, I can only rely on myself. The body, mind, and time are the investments to achieve this greatness, and he understands these truths.

For nearly two months, his training plan continued in an orderly manner. Every morning, I get up at dawn and run, from jogging at the beginning to slowly accelerating to normal running. Following this, there are about an hour's worth of push-ups, sit-ups, frog jumps, pull-ups, and other exercises before breakfast. Post-breakfast, it was training camp on the Uchiha training grounds till noon.

After lunch, read a book for two hours and take a one-hour nap. In the evening, I practice swordsmanship, shuriken throwing, and hand sealing for an hour. At night, before going to bed, I meditate, trying to understand the flow of chakra in my body and get a feel for it. This would help later with chakra control.

There's no way he could become a high-level ninja, even at chakra control or chakra quality, without cheating or using a system, especially at just four years old. So he can only trust the process and improve day by day.

Although this kind of life is a bit boring, it is somewhat unavoidable. The world of the Hokage is not technologically mature. Now, after 36 years of its establishment, things like refrigerators, microwave ovens, and the like have appeared. Well! The TV should be present, but its primary purpose is surveillance or movie theater screenings. There is a dearth of available entertainment options. Even adults in the previous world would feel bored and disappointed with the nightlife, not to mention the children.

When it comes to throwing out ninjutsu, Toshiro is not in a hurry. Konoha hasn't yet reached the time for him to go to war. In his plans, until he goes to the academy, taijutsu and endurance training are his first choices. He prioritizes the development of chakra and control skills, and of course, not overlooking swordsmanship, sealing, and shuriken throwing. Learning these at the starting stage would provide him with ample time to work on ninjutsu when he has enough chakra.

People need to set a goal for themselves, and only with a goal can they find the right direction and succeed. For now, these are my goals.

Become a Shinobi by age 8.

Open Sharingan by age 7.

Survive the Third Great Ninja War.

As for becoming a Kage-level shinobi, opening the Mangekyo Sharingan, avoiding the tragedy of the family, and defeating the mastermind behind the scenes, aka black Zetsu, You can consider these options, but it all depends on the specific situation.

It's not that he doesn't want to have a big goal. The problem is that he isn't completely sure about opening the Mangekyo. After all, what are the conditions for opening his eyes? As a modern person with normal views, he can't do things like Indra and kill his friends off. And because he is an only child and has no brothers, the chance of opening the Eternal Mangekyo is zero. As for transplanting Hashirama cells, he can't get them, even if he wants them. And no one likes to have another human face on their body. Even if that person is the first Hokage.
