Naruto: God-Level System

"I know you want to increase your strength quickly, Mikoto, but cultivation requires a gradual approach. Otherwise, you will only end up hurting yourself." Hyuga Shin's expression was slightly stern.

"Mm! I understand, Shin." Mikoto nodded, though her eyes still betrayed a sense of determination.

Mikoto was the type of person who was soft on the outside but firm on the inside; once she made up her mind, she would do whatever it took to achieve it, even if it meant risking her life.

Hyuga Shin knew that Mikoto hadn't really taken his words to heart. He couldn't help but show a helpless expression on his young face. Having lived with Mikoto for over half a year, he understood her personality very well.

"Actually, as long as your Sharingan evolves, your strength will increase rapidly. If you can evolve it into a Mangekyo Sharingan, Kage-level strength is guaranteed."

Mikoto shook her head. "In the entire Uchiha Clan, legend has it that only Madara Uchiha ever evolved those supreme eyes. It is incredibly difficult to evolve into a Mangekyo."

Hyuga Shin smiled. Having watched Naruto, he knew the methods for awakening the Mangekyo like the back of his hand.

If Hyuga Shin himself possessed a Sharingan, he might not necessarily be able to awaken a Mangekyo, but helping someone else awaken one was a relatively simple matter.

As long as an Uchiha clansman had decent talent, Hyuga Shin could help them awaken it, though the methods were too brutal; he didn't want to use them on Mikoto.

If Hyuga Shin were to use Genjutsu: Terror Reincarnation on Mikoto right now, he could at least force her to awaken the Three-Tomoe.

However, it would likely leave an indelible psychological trauma in Mikoto's heart, and the cost would outweigh the benefits.

"Don't worry, Mikoto! I have a way to awaken the Mangekyo Sharingan, but you will have to suffer a bit. I just hope you won't beat me up afterward," Hyuga Shin said with a laugh.

He had already thought of a way to help Mikoto awaken the Mangekyo, but she would have to endure some stimulation. It was unavoidable—who told the Uchiha Clan to be such a twisted family?

One had to suffer mental trauma to awaken the Mangekyo.

"Really?" Mikoto found it hard to believe, yet she chose to trust Shin.

"Of course it's true, but Mikoto, there is one thing I must tell you."

"What is it? Even if I can't awaken the Mangekyo, it doesn't matter. I never really expected to awaken it anyway."

"Awakening the Mangekyo Sharingan is possible, but it has a side effect: excessive use leads to deteriorating vision, or even blindness," Hyuga Shin said with a serious face.

The side effects of the Mangekyo Sharingan were no small matter.

After a long silence, Mikoto looked up and said, "If the side effects of the Mangekyo Sharingan are truly that severe, then let's not awaken it."

Compared to immense power, she preferred being able to see Shin every day.

"Don't worry! I should be able to find a way to evolve it into an Eternal Mangekyo Sharingan, so there won't be any side effects," Hyuga Shin comforted her with a smile.

He possessed a system, and with an omnipotent system at his disposal, solving the side effects of the Mangekyo should be a trivial matter.

"Eternal Mangekyo Sharingan?"

Mikoto looked at Hyuga Shin in confusion. She knew about the Sharingan—to be precise, every Uchiha clansman currently knew about the Mangekyo Sharingan.

But she had truly never heard of an Eternal Mangekyo Sharingan.

"Hey! What are you two whispering about over there?" Nawaki shouted from a distance.

"Nothing!" Hyuga Shin replied, then whispered, "I'll explain the Eternal Mangekyo Sharingan to you when we get back."

The Ninja Academy was very relaxed; usually, school let out after four o'clock. This made Hyuga Shin feel quite pleased—it was much better than the schools in his previous life.

Moreover, the Ninja Academy had a high degree of freedom. As long as your practical grades were good, you could manage your own time during the afternoon practical classes.

Chapter 37: Mangekyo, Eternal Mangekyo

After school, they said goodbye to their classmates, and Hyuga Shin and Mikoto headed home.

Although Hyuga Hiashi and Hizashi Hyuga were heading in the same direction, they didn't walk together; mainly because Hyuga Shin found having two "big lightbulbs" around annoying.

After returning home, Mikoto suppressed her curiosity and went to prepare dinner. Once they finished eating, Mikoto looked at Hyuga Shin with her adorable, wide eyes.

Seeing Mikoto's anticipation, Hyuga Shin gave a light cough and began to show off his knowledge.

However, when it came down to it, he didn't know where to start. Should he begin from the creation of the world?

"Let's start with the Uchiha Clan. The Uchiha Clan is very extreme and their thinking is quite radical; you should be aware of that, Mikoto."

Mikoto nodded. It was true; she had lived in the Uchiha Clan since she was a child, and she knew this better than Hyuga Shin.

Hyuga Shin continued, "Most Uchiha clansmen awaken their eyes when they encounter a major change or a life-or-death crisis."

"In my view, the awakening of the Sharingan is a result of extreme mental fluctuation that breaks the internal limitations, awakening the Sharingan hidden within the bloodline."

"Awakening the Sharingan is a bit troublesome, but once awakened, evolving from one-tomoe to three-tomoe is relatively simple. I estimate that it can be evolved through accumulation," Hyuga Shin speculated.

He didn't have a Sharingan himself, so he could only guess. Whether he was right or wrong, he couldn't be sure, but it didn't matter—with Mikoto's talent, she could definitely awaken the three-tomoe.

"Setting aside the Tomoe Sharingan, let's talk about the Mangekyo Sharingan. To awaken it, one must pay a great price, such as witnessing the death of someone closest to them."

Upon hearing this, Mikoto's pupils shrank violently. The person closest to her right now was Hyuga Shin. If it required his death to awaken the Mangekyo, she would rather never awaken it at all.

Seeing Mikoto's tension, Hyuga Shin comforted her, "Don't be nervous. Actually, that isn't the only way to awaken the Mangekyo."

Afterward, Hyuga Shin took out two small saline bottles containing two three-tomoe Sharingan eyes. The pupil power contained within them gave Mikoto an incredibly powerful sense of oppression.

"Shin, these Sharingan are...?"

"They belonged to Uchiha Akito, and these eyes have already evolved into the Mangekyo."

Mikoto was deeply shocked. "Uchiha Akito actually awakened the legendary Mangekyo Sharingan?"

"Yes, I helped him awaken them," Hyuga Shin said with a smile, without explaining the specific circumstances.

Mikoto was not shocked that he had killed Uchiha Akito and then gouged out his eyes, which left Hyuga Shin feeling very surprised.

Seeming to perceive Hyuga Shin's surprise, Mikoto said firmly, "You are the only one closest to me now, Shin. No matter what you do, I will support you."

Hyuga Shin remained silent for a long time before he began to continue, silently tucking Mikoto's words into his heart.

"Set the Mangekyo Sharingan aside for a moment; what we need to discuss is the Eternal Mangekyo Sharingan. Awakening the Eternal Mangekyo is dozens of times harder than awakening the Mangekyo."

"To awaken the Eternal Mangekyo, one must possess a Mangekyo Sharingan and then transplant the Mangekyo of a sibling."

This condition is incredibly perverse. If you want the Eternal Mangekyo, you must ensure you can awaken the Mangekyo yourself, ensure you have siblings, and then ensure those siblings also awaken the Mangekyo.

The probability of this is truly outrageously small.

"With conditions like these, has anyone actually awakened the Eternal Mangekyo?" Mikoto asked, her mouth agape.

"There is indeed, and you know him as well: Madara Uchiha. When Madara Uchiha's younger brother, Izuna Uchiha, died, he gave his Sharingan to Madara. It was precisely this accident that brought about the birth of the Eternal Mangekyo."

"However, there is definitely more than one way to evolve into the Eternal Mangekyo; there must be other methods." A gleam shone in Hyuga Shin's eyes.
