Sharingan

The first day of school ended, and Uchiha Nagi returned to this dilapidated home.

"Have you already left?"

Discovering that Uchiha Eri was no longer home, Uchiha Nagi let out a sigh.

The other party was only a thirteen-year-old child, yet she had to shoulder the burden of earning money to support the family.

At his current physical age of only six, he simply couldn't be of any help.

Shaking his head, Uchiha Nagi set down the pile of textbooks issued by the school; the knowledge contained within them covered a very broad range.

If one were to measure by his previous life, it included mathematics, physics, and chemistry...

It was just a pity that the only purpose for these subjects in these textbooks was to allow the learner to better master the methods of killing.

For instance, learning parabolas was to better throw shuriken or kunai;

Learning the chemical properties of combustion was for the various ways to utilize Fire Release, and so on.

A ninja is, and always will be, a violent profession.

However, with these subjects integrated into the textbooks, it was indeed difficult for them, at only primary school age, to fully grasp everything.

Looking at it this way, if the Hokage really wanted to develop technology, they should be able to advance very quickly; unfortunately, those in this world who mastered this knowledge did not have their ambitions set there.

Uchiha Nagi thought about the strength that those Six Paths level figures in the ninja world would eventually display, which really could not be compared to low-level science.

Things like space-time teleportation—those who could master such things were at least of a high-level civilization.

In the Hokage's domain, there were not a few people who could master it.

Do not mistake Summoning Jutsu for anything other than space-time ninjutsu!

Uchiha Nagi shook his head, recalling the basic knowledge the teacher had taught today.

"Let's try the Chakra Refinement Technique first."

Originally, Uchiha Nagi's parents were both Chunin, and according to their initial plan, they were going to start teaching him the Chakra Refinement Technique as soon as he turned six.

It wasn't that they didn't want to teach him earlier, but chakra refinement was not a case of "the earlier, the better."

As everyone knew, chakra was formed by the combination of physical energy and spiritual energy; it would not increase in total volume just because you started refining it a few years earlier.

Physical energy, in particular, was closely related to one's constitution; refining it too early meant competing for the energy needed for physical development.

If a child were ignorant and extracted too much physical energy, the damage to a body still in development would be irreversible.

Therefore, his parents likely wanted to wait until he was more sensible and understood the pros and cons before teaching him.

But unfortunately, after Uchiha Nagi turned six, his parents were no longer around.

Although there was Uchiha Eri, she was only a Genin; of course, teaching these basic skills would not have been a problem.

However, she was always out on missions, and she was already exhausted every time she returned, so Uchiha Nagi did not want to trouble her.

After all, he would be entering school soon, and there was not much difference between learning these basics a day earlier or a day later.

Following the knowledge learned in class, Uchiha Nagi began to attempt it.

Although theoretically, chakra refinement did not require special preparation, he still took a deep breath, sat cross-legged, and devoted himself entirely to it.

Before long, Uchiha Nagi opened his eyes with a strange expression.

He had not failed; on the contrary, he had succeeded. Chakra refinement was... much easier than he had imagined.

Although it was not a difficult task in itself, the fact that he learned to refine chakra from scratch in just a moment probably proved something.

"Could it be that I have quite a good talent?"

Uchiha Nagi raised an eyebrow. If that were true, that would be great.

Up until now, he hadn't discovered any "golden finger" or cheat system.

And it was not easy to survive safely in this world of Hokage, which was why he had been so eager to cling to Namikaze Minato's leg.

Now it seemed that relying on his own strength might not be bad either, even if it was a bit tiring and troublesome.

Uchiha Nagi clicked his tongue; then, it was decided.

He would first try to see if he could become a powerhouse himself, while not stopping his efforts to cling to the big shot. In this way, wouldn't he have double insurance? Profit!

"There is one more thing to try." Uchiha Nagi looked at the familiar surroundings.

Even though this was his home, and generally no one would come to the edge of the clan grounds.

Uchiha Nagi still checked carefully, and only after confirming that no one would come did he act.

He solemnly walked in front of a mirror and channeled the chakra he had just refined toward his eyes.

Soon, that pair of eyes, originally as black as ink, turned blood-red, with two tomoe embedded within them.

That's right, this was a pair of Two-Tomoe Sharingan!

If this news were known to the Uchiha higher-ups, his life would completely bid farewell to peace and stability.

One must know that, according to the normal process, Uchiha Itachi was already eight years old when he awakened his eyes, and it was only a single tomoe.

Even so, Uchiha Itachi was considered a young genius of the Uchiha Clan, and only Uchiha Shisui could be mentioned in the same breath as him.

Uchiha Nagi had not only awakened the Two-Tomoe Sharingan, but he was also only six years old.

It was easy to imagine that once his Sharingan was exposed, it would inevitably trigger a storm within the Uchiha Clan.

As the person who caused this storm, his life path would certainly be altered from this point on.

At the very least, living a peaceful life would no longer be possible; he would likely be subjected to brainwashing rhetoric about the glory of the Uchiha...

That was why Uchiha Nagi did not want anyone to know he had awakened the Sharingan, not even Uchiha Eri.

"It really is a Two-Tomoe Sharingan."

Uchiha Nagi looked at his eyes in the mirror, feeling somewhat surprised. In fact, this was his first time seeing his own Sharingan.

He had known he should have awakened the Sharingan, but since he did not know how to refine chakra, he had been unable to manifest it.

The awakening occurred the moment he regained the memories of his past life; the massive cognitive dissonance and the shock to his worldview triggered a mental fluctuation that successfully unlocked the Sharingan—and a Two-Tomoe one at that.

He even suspected that if his mental energy hadn't been a limiting factor, his Sharingan might have surged directly to the Three-Tomoe stage.

One had to remember that even the Second Pillar only reached the "Three-Tomoe" stage after the massive trauma of his clan's extermination.

At this moment, Uchiha Nagi felt a sense of relief.

"Fortunately, the special chakra required to awaken the eyes is generated by the body's instincts. Otherwise, once I grew accustomed to this world, I would have needed new stimulation to awaken the Sharingan."

As it stood, with the simple accumulation of time, it should be relatively easy for his Sharingan to evolve into the Three-Tomoe stage.

The problem lay in the transition from Three-Tomoe to Mangekyo Sharingan.

Based on what he knew, aside from Sarada in Boruto, every Uchiha in the Naruto series who awakened the Mangekyo Sharingan did so by killing a close friend or family member.

If he were to follow that path, Uchiha Nagi naturally had a candidate in mind: Uchiha Eri.

But...

"Relying on killing someone close to me to awaken the Mangekyo—I'd rather not awaken it at all."

Uchiha Nagi shook his head. This was impossible; it diverged too greatly from his values.

His pursuit of power was meant to secure a peaceful life and ensure he didn't have to live so exhaustingly.

And yet, he was expected to kill someone he cared about just to unlock the Mangekyo Sharingan?

Wouldn't that be completely backwards?

Therefore, even if he needed to awaken the Mangekyo Sharingan, he would only attempt the method used by Sarada.

Furthermore, he felt that Uchiha Eri's current place in his heart probably hadn't reached the level required to trigger his Mangekyo.

His thoughts concluded, and Uchiha Nagi sensed his chakra levels; they had been nearly depleted by this pair of Two-Tomoe Sharingan.

"Less consumption than I imagined."

Uchiha Nagi muttered to himself. Considering he had only refined a portion of his chakra and it had lasted this long, if he refined it at full capacity, he could sustain it for a considerable amount of time.

Even if he wasn't using its abilities during that time, one had to remember that his body was only six years old, and the amount of chakra he could safely refine was pitifully small.

Once he graduated and his body had fully developed, the consumption of the Sharingan should pose no problem for him at all.

"So, Hatake Kakashi's high consumption is indeed because he isn't of the Uchiha Clan, compounded by the fact that he cannot deactivate the Sharingan."

"For an Uchiha, the consumption is actually quite manageable if the eyes are just being maintained."

Uchiha Nagi nodded with satisfaction. Indeed, the Sharingan was meant for an Uchiha.

Moreover, having the Two-Tomoe Sharingan made many things much more convenient.

For instance, when it came to acquiring ninjutsu, he could rely on the Sharingan's ability to copy techniques.

He had previously been hesitant about how to obtain the Shadow Clone Technique to accelerate his training, but with the Two-Tomoe Sharingan, that was no longer an issue.

There were plenty of ninjas in Konoha who knew the Shadow Clone Technique. Even if he lacked Hatake Kakashi's experience and couldn't learn it after seeing it once, he could just watch it a few more times.

Uchiha Nagi wore a smile.

"An Uchiha start doesn't seem so bad. If I had really become an ordinary person, acquiring ninjutsu would have been a hassle; I might have even had to craft a 'genius' persona to secure investment from the higher-ups..."

Thinking of that, Uchiha Nagi shuddered. That would be too exhausting and troublesome—the exact opposite of his pursuit of a peaceful life!

That was absolutely out of the question!

"Gurgle~~"

Just then, Uchiha Nagi's stomach suddenly growled.

"It's half an hour before my usual mealtime, and I'm hungrier than usual. It must be the toll of refining chakra."

He rubbed his stomach. It was too late to cook, so he would just make do with instant noodles.

As long as he wasn't eating instant noodles for every meal, every day, the nutritional impact wouldn't be too severe.

Still, it looked like he would need to increase his intake of meat, eggs, and dairy. That expense...

Uchiha Nagi sighed. Indeed, being a ninja was an incredibly expensive profession!
