Running amok: Starting from Naruto

Father!

He and Uchiha Mikoto had a child of their own.

It's a boy.

When the child was born and opened his eyes, a bright red color caught Fugaku's eyes.

Born with eyes open!

The overjoyed Uchiha Fugaku regarded this child as the hope for the future of the Uchiha clan and named him Seiichi, Uchiha Seiichi.

……

Shengyi here was also a little confused.

Isn't he already dead?

Died just before the development of a special medicine.

5 minutes.

Just 5 minutes left.

In Shengyi's previous life, he was born into a wealthy family with great power and influence, and his family was prosperous.

It is said that let children win at the starting line.

Then he can say that he was born directly on the podium.

He has regular features and a dignified appearance.

IQ over 140.

He has a cheerful personality, a harmonious family, and is friendly to his brothers.

At the age of 9, he was admitted to the top junior class in the country.

It can be said that when he was 9 years old, he had everything that most ordinary people dream of throughout their lives.

But, things don't always go as planned.

When he was 10 years old, he fell on the playground of his university school and was diagnosed with muscular dystrophy, a terminal disease.

However, he did not become discouraged nor did he give up on himself.

He chose to drop out of school.

Study biology and medical knowledge at home.

At first, the doctor asserted that he would not live to adulthood, but later changed his statement to say that he would not live to the age of 22, then to the age of 25, and then to the age of 30.

He successfully extended his life time and time again.

Finally, under his leadership, a specific drug for treating muscular atrophy was successfully developed.

However, his life ended at the age of 34.

The picture freezes at a time when there are still 5 minutes left for the new special medicine to be successfully synthesized.

……

But none of this matters anymore.

Shengyi just wanted to know what was going on with his current baby body?

Reborn?

cross?

In his previous life, Shengyi was under too much pressure, so he chose to relax and read a lot of online novels and animations.

But isn’t that thing written for fun?

Are you serious?

As his thoughts tumbled, he felt his eyes getting a little hot. He pushed open his heavy eyelids and saw a tall, fierce-looking man with red eyes staring at him.

A baby's body doesn't support him thinking too much.

After taking a quick look, he fell into a deep sleep.

time flies.

In the blink of an eye, it was already the 43rd year of Konoha.

The baby who had difficulty opening his eyes has grown into a cute 5-year-old boy.

This boy inherited the handsome looks of the Uchiha clan, and was even more outstanding.

He has a bun hairstyle with a strand of hair falling on his forehead, which makes him handsome and cool, and looks clean and neat.

"Father, don't get excited. Mother and brother will be fine."

Looking at Uchiha Fugaku struggling back and forth in the yard, Shengyi felt a little dizzy.

"You are still young, you don't understand! By the way, why do you say you are my younger brother?"

"intuition!"

"Congratulations, Chief. Mother and child are safe!"

Fugaku was also very happy when he heard this.

When I could go in, I ran in as soon as possible.

Shengyi followed behind, neither hurried nor slow.

"Mikoto, look, this is our second son."

“It’s a bit ugly.”

Shengyi stood on tiptoe to take a look, and what he said made everyone in the room laugh.

"All newborns are like this. They will grow out of it after a while. In our Uchiha clan, no one is ugly, regardless of gender."

Shengyi thought about it and it seemed to be true. At least in his memory, there was not a single ugly Uchiha clan member with a name. They became even more handsome after opening their eyes.

Not like the Hyuga clan.

Except for Hinata and her two sisters and Neji and his two siblings, no one is good-looking. They become uglier after opening their eyes! The three good-looking ones also become ugly!

"Itachi, just call you Uchiha Itachi."

Everyone present was laughing, except Shengyi.

Because apart from him, no one else knows what the name 'Itachi' means.

Although Itachi in the original work was tricked and did many unforgivable things.

But in Shengyi's opinion, he expressed that it was understandable.

Itachi had never studied seriously, and in the end he chose to graduate early, taking an exam on martial arts.

In his previous life, he was a semi-illiterate person who had only graduated from elementary school and was lucky enough to be able to recognize words. How could we expect him to have profound insights?

impossible.

So, for such a simple-minded semi-illiterate person who has been brainwashed since he was a few years old, it would be hard for him not to be lame.

Shengyi said that it is still early and there is still time for everything.

This tool brother, he is determined to do it, he said!

Seiichi usually asked Fugaku to find him a lot of information about bloodline limits in the ninja world, and also checked the ancestral home of the Uchiha clan.

In this regard, he gradually made some new discoveries.

The Uchiha clan's bloodline is incomplete, or rather, it has defects!

Reasoning backwards from what he knows to be the end result.

1. The Uchiha clan needs strong emotional stimulation to open their eyes. It takes extreme emotional stimulation to open the Mangekyō Sharingan.

Second, using the Mangekyō Sharingan too much can easily lead to blindness.

3. The Mangekyō Sharingan requires a pair of brothers' eyes to combine into the Eternal Mangekyō Sharingan.

Fourth, the ultimate yin attribute represented by the Eternal Mangekyō Sharingan, combined with the ultimate yang attribute represented by the body of the sage Hashirama Senju, can create the true sage's eye - the Rinnegan.

Reverse reasoning based on the above data.

Opening the eyes, including the Mangekyō Sharingan, means that the opening of the Sharingan is related to spiritual power, which is the Yin attribute.

But the Uchiha clan had no method to train Yin attributes, and could only choose to use rough emotional stimulation.

The advantage of this method is that it is simple to operate.

The downside is that after opening your eyes, your personality changes drastically and you may go crazy easily!

But the Hyuga clan, which also originated from the Otsutsuki clan and belongs to the same Konoha eye-jutsu family, does not have so many problems.

The upper limit of the Byakugan is also very high, and the Samsara Eye and the Rinnegan are at the same level.

But the eye roll is not so complicated.

Whether it is opening the eyes or using it, it is very stable and there is no hidden danger.

This is absolutely wrong.

"Stimulation to open the eyes, blindness, eye replacement... Wait, I think I know!"

Shengyi sat on the steps of the courtyard corridor, feeling that he had missed some important clue.

But I just can't think of it.

Until I saw the fruit fall from the tree in the yard and kill a small insect.

He finally knew what the clue was that he had been ignoring.

Shengyi took out a piece of paper and wrote down his analysis in the small seal script of his previous life.

Hinata: Byakugan → Samsaragan, gone.

Uchiha: One Magatama Sharingan → Two Magatama Sharingan → Three Magatama Sharingan → Mangekyō Sharingan → Eternal Mangekyō Sharingan → Rinnegan.

In Seiichi's memory, the Six Paths Sage did not have the so-called Mangekyō Sharingan.

It's directly from the three-magatama Sharingan to the Samsara Eye.

But the Six Paths Sage's son has the Mangekyō Sharingan.

Although there are only two steps to evolve the Byakugan into the Rinnegan, these two steps are as hard as a fall from heaven. From beginning to end, no one has been able to successfully evolve their Byakugan into the Rinnegan.

Chapter 2 Found the problem, how to solve it

Although there are many steps to evolve the Sharingan, it also facilitates the evolution of the Uchiha clan.

Looking at it this way, the result is very clear.

The hidden danger to the Uchiha clan's bloodline was most likely caused by the Six Paths Sage.

The two sons of the Six Paths Sage inherited his sage body and sage eyes respectively.

The immortal is in good health, his physique has just been enhanced.

But the problem with the Immortal Eye is big.

Without an immortal body, an ordinary person's body cannot drive the immortal eyes at all.

Forced use is using lifespan as fuel.

For details, please refer to the long gate that quickly becomes an adult human specimen.

The incomplete immortal bodies are like that, let alone those who have no immortal bodies.

So, the Six Paths Sage did this in order to save his son's life.

He could only manually weaken the strength of his son's immortal eyes.

Keep weakening it again and again until it returns to its original one-magatama state, so that the Sage Eye can be improved along with the strength of the owner of the eye.

It not only ensures power, but also does not bring too much burden to the owner of the eye.

But the Six Paths Sage probably didn't expect that weakening would come at a price.

The part that was cut off made the originally complete bloodline appear incomplete.
