Mangekyo Sharingan Awakening Experiment

After the contributions of dozens of death-row prisoners over this period, Uchiha Yansheng's Emotional Potion had finally produced its first results.

What he needed next was a test subject.

He did not dare use something that had just been made and never tested on himself.

After thinking briefly, Uchiha Yansheng took the potion and went to find Fugaku Uchiha.

That night, Fugaku Uchiha, Shisui Uchiha, and Itachi Uchiha arrived together at Uchiha Yansheng's laboratory.

When the three of them arrived, Uchiha Yansheng was conducting Sharingan cloning experiments.

By now, Uchiha Yansheng had mastered the technology for rapid cell growth and had successfully awakened the cloned Sharingan.

Unfortunately, the cloned Sharingan were only One-Tomoe Sharingan. Uchiha Yansheng had yet to find a way to increase a Sharingan's ocular power.

Perhaps cultivating them with Hashirama Cells would work, but that would take far too long. They were only Three-Tomoe Sharingan; there was no need to go to such lengths.

As Fugaku Uchiha watched the One-Tomoe Sharingan before Uchiha Yansheng suddenly wither, a flicker of heartache crossed his face.

But he quickly came to his senses. Where had this One-Tomoe Sharingan come from?

Uchiha Yansheng did have a stockpile of Sharingan, but they were basically all Three-Tomoe Sharingan. There were not even any Two-Tomoe Sharingan, much less One-Tomoe Sharingan.

"Yansheng... this eye..."

Fugaku Uchiha could no longer concern himself with anything else and hurriedly asked.

If Uchiha Yansheng truly could clone Sharingan, would that be a good thing or a bad thing for the Uchiha Clan?

"Just a failed product..."

"Alright, since all three of you are here, does that mean Itachi has decided to become my test subject?"

Uchiha Yansheng looked the three of them over and spoke slowly.

"I naturally will not pass up a chance to obtain the Mangekyo Sharingan."

"However, Yansheng... there is a question I want answered. The genjutsu you showed me not long ago..."

Itachi Uchiha asked Uchiha Yansheng the question that had been troubling him all this time.

"Oh, that? Didn't I tell you? That was going to be your future. It was simply a future I had already changed."

"To be honest, I don't like you very much. You're too stupid. What kind of mindset made you choose to join forces with a traitor and slaughter the entire Uchiha Clan?"

"If I had not awakened the power to see the future, I estimate I would have been one of the people you slaughtered."

Uchiha Yansheng's words left Fugaku Uchiha beside him dumbfounded. This was the first time he had heard that the Uchiha Clan's future would become like this.

No matter what, he refused to believe that his son would make such a choice.

Faced with Uchiha Yansheng's accusation, Itachi Uchiha merely fell silent and offered no opinion.

Uchiha Yansheng did not care about his attitude. As he adjusted the dosage of the Emotional Potion, he continued speaking.

"Forget it. Perhaps I've seen too many futures. Sometimes, I don't care much about such things anymore. Anyway, as long as I'm here, if you make that choice again, I'll kill you first."

"Do you know why I chose you for this experiment?"

"It is not because you awakened the Mangekyo Sharingan in the future I saw, but because you possess the aptitude to awaken the Mangekyo Sharingan."

"Don't think the aptitude I mean is talent or anything like that. The Uchiha Clan's aptitude for the Sharingan is not about mastery of ninjutsu, but... emotion!"

Upon hearing the word emotion, Itachi Uchiha abruptly raised his head and stared directly at Uchiha Yansheng, his gaze burning.

"You really are... stupid! Yet it is precisely fools like you, who value feelings so deeply, who can more easily awaken the Mangekyo Sharingan."

Uchiha Yansheng shook his head helplessly and reminded him.

"If you are still alive later, go look through the clan's history. Do not focus on the names of those with Mangekyo Sharingan; look at what they experienced before awakening them."

"You have always believed that the Uchiha Clan is a clan that values power."

"But in truth, the more someone values power and scorns emotion, the less capable they are of awakening the Mangekyo Sharingan. Some cannot even awaken the Sharingan."

"And the less someone cares about the Mangekyo Sharingan, the greater their chances of awakening it instead."

"They say the Uchiha Clan is easily misunderstood by others, but in truth, even the members within the clan misunderstand the clan."

After saying this, Uchiha Yansheng injected a tube of potion into Itachi Uchiha's body. After observing him for a moment, he gave Shisui Uchiha beside him an order.

"Next, it is up to you. What you need to do now is make Itachi Uchiha sink into his inner memories. Cast a genjutsu on him, and use the power of Kotoamatsukami."

Upon hearing Uchiha Yansheng's words, Shisui Uchiha nodded and used Kotoamatsukami on Itachi Uchiha.

"What you need to do is not control Itachi Uchiha, but make him believe that the world in the earlier genjutsu was real."

"Only by making him completely immerse himself in the world of the genjutsu will there be a chance for him to awaken the Mangekyo Sharingan."

"And once he awakens it, he will be able to break free from the illusion himself, so you need not worry about his safety."

Under Shisui Uchiha's Kotoamatsukami and the effects of the potion, Itachi Uchiha began to sink into the world of the genjutsu.

Uchiha Yansheng had already tried it. No matter how tragic the experience in an ordinary genjutsu was, it likely could not make someone awaken the Mangekyo Sharingan.

Therefore, even with Shisui Uchiha's Kotoamatsukami, Uchiha Yansheng was still not entirely at ease. During their conversation just now, he had already used a Three-Tomoe Sharingan to activate Izanami.

Izanagi's effect was to impose a genjutsu upon the entire world, thereby changing reality according to the caster's will.

Izanami, on the other hand, used several conspicuous points to trap an enemy in a real illusion capable of looping.

Within Izanagi's real environment, the target's perception of time and the outside world would be weakened, causing them to sink into that real environment.

As for breaking free from Izanami through profound enlightenment and sincere repentance, that was merely a condition imposed by the caster.

After all, Izanami had been created to save people.

Naturally, that condition could be changed.

In other words, Izanami's ability was to make someone fall into an eternal illusion.

With everything prepared, this Mangekyo Sharingan awakening experiment targeting Itachi Uchiha had officially begun.

As for what the outcome would be, no one knew.

But the most important thing now was recording the various conditions within Itachi Uchiha's body.

Thus, Uchiha Yansheng quietly activated the penetrative ability of the Byakugan and closely monitored everything inside Itachi Uchiha's body at all times.

The only known side effect of using the Byakugan's ability was fatigue, so Uchiha Yansheng used it without concern. There should not be any problems in the short term.

If something unexpected happened, he could always follow Orochimaru's example and switch to another body.

He had prepared so many clones precisely to guard against all kinds of accidents.

Time passed quickly within the genjutsu, and Uchiha Yansheng soon collected data on the changes occurring in Itachi Uchiha's brain.

The change did not come from the brain itself, but from a special chakra produced within it.

It turned out that Uchiha Yansheng had gone down the wrong path. What was needed to awaken the Mangekyo Sharingan was not some kind of hormone, but a special chakra produced by the brain.

This chakra should emerge under extreme emotions.

After this special chakra appeared, it would actively affect the optic nerves, causing changes in the eyes and thus forming the Mangekyo Sharingan.

"I've really been focusing too much on Kekkei Genkai lately. I actually forgot the reality I had always understood."

"Chakra is the root of everything."
