Reborn into Naruto World with Tenseigan

Looking at the pair of Eternal Mangekyou Sharingan in Shisui’s eye sockets, Kuroto had a thoughtful expression for a while, then clearing up the thought he said to Shisui, “You should take a good rest, at present, your body has just gone through genetic changes which is undoubtedly a very tiring process, so plenty of rest is necessary. Additionally, there are chances of unstable elements to appear, so you have to be aware of them too.”

According to Kuroto’s estimation, even if the implantation operation is completed, it won’t be considered truly completed until all the hidden dangers are eliminated and the genetic change is completely stabilized, which will take at least two weeks to a month of recovery and analysis.

Shisui was already in an exhausted state, so after listening to Kuroto’s words, he nodded, closed his eyes, and soon fell asleep.

The implantation operation even with a 100% success rate was no short of a life and death battle for him, perhaps it was even more tiring than any life and death battle he has participated in up to now as such he really needed a short nap to be able to recover the bare minimum before he goes back to his home.

Kuroto did not disturb Shisui, and while Shisui was sleeping, Kuroto cleaned up the messy Operation Room, realigned the fallen devices and monitors, and then reconnected them to Shisui’s body.

And while recording the data displayed on various monitors, Kuroto started analyzing the result of the operation.

Without a doubt after the successful implantation of Hashirama Cells, Yin and Yang Chakra in Shisui’s body have fused, and the Eternal Mangekyou Sharingan is currently in Shisui’s eye sockets and has also entered a state of evolution.

But perhaps because the stimulation for evolution wasn’t enough, this state of evolution did not continue and stopped midway.

As per Kuroto’s speculation, there may be three reasons for the failure in evolution.

First is the lack of Otsutsuki Indra’s Chakra.

It is stated that Hagoromo’s Chakra is necessary for awakening the Rinnegan.

The Chakra of Asura was obtained from Hashirama Cells, and if, for the awakening of Rinnegan, the chakra of both Asura and Indra are really needed, then the reason for failure this time was the lack of Indra’s Chakra.

The second speculation is that Shisui is not the original owner of the Eternal Mangekyou Sharingan in his eyes.

The original owner of this pair of Eternal Mangekyou is Uchiha Ryota, perhaps Uchiha Ryota’s body must be used as a breeding ground for the evolution of this pair of Eternal Mangekyou Sharingan into the Rinnegan.

After all, Madara’s Rinnegan evolved from his own Eternal Mangekyou Sharingan.

And the third speculation in Kuroto’s mind is the lack of Chakra as a whole.

This speculation of Kuroto is not without a reason, it must not be forgotten that the Battle of the Valley of the End took place when both Senju Hashirama and Uchiha Madara were probably in their thirties, so in a way, both of them were in their prime. At the end of the war, Madara faked his death with Izanagi through a time transcription seal, managed to obtain Shodaime’s Cells, and later implanted them into his body.

But he did not awaken the Rinnegan until his old age when he was near death, as such he had no choice but to foster the Rinnegan in Nagato who has the Uzumaki blood and hoped to be later revived by the ‘Samsara of Heavenly Life Jutsu.’

From this point, it can be confirmed that Madara did not awaken the Rinnegan until decades later in the battle of the Valley of the End.

So, what took Madara such a long time to awaken the Rinnegan?

Kuroto speculates two possible reasons for such a long delay:

First is that because Madara has used ‘Izanagi’ so he completely lost the visual prowess of one of his eyes, therefore, even if Madara has Otsutsuki Indra’s Chakra along with the Eternal Mangekyou Sharingan, with just the visual prowess of a single eye, the Yin Chakra in his body was not enough.

He had to wait for years for his visual prowess to be restored because of the Hashirama Cells, then further wait for the Yin and Yang in his body to merge to finally awaken the Rinnegan when he was closer to death.

The second speculation is that the evolution of Rinnegan from the Eternal Mangekyou Sharingan takes a very large volume of Chakra in addition to right stimulation, so the reason why he stayed in the dormancy even after the death of Shodaime Hokage was to continuously accumulate Chakra.

It can be assumed just how huge would be the Volume of Chakra if a powerhouse like Madara took several decades to accumulate.

Of course, it’s also possible that both reasons are correct.

But anyway, even if a single conjecture of Kuroto is correct, then it can be judged that the evolution of Eternal Mangekyou into Rinnegan is still a very far sight in the future, and when reaching this conclusion, Kuroto can’t help but think, ‘Awakening Rinnegan might really be not as simple as I had assumed initially.’

But Kuroto was not disappointed.

Kuroto’s main objective is the Project Godhood, everything else is just some side hustle or hobby that Kuroto occasionally takes interest in, if they succeed then well and good, but if not, then he will not delve too much of his time into them unless these side hustle and hobbies are related to his Project Godhood.

About 2 hours later, Kuroto and Shisui slowly walked out of the secret laboratory, of course, Shisui couldn’t walk on his own because of weakness, thus Kuroto helped him.

Itachi who had been keeping watch over the surrounding for all this while noticed the arrival of the two, at the same time he also noticed that although Shisui looks weak and tired, he was still smiling and talking a bit cheerfully with Kuroto, which means that, ‘Implantation Operation was successful!’

This was Itachi’s conclusion, and after understanding this, he hurriedly greeted the two with a joyful expression, “I knew you would successfully make it Shisui-san.”

Shisui smiled bitterly and shook his head, he wanted to tease Itachi for worrying too much but did not have enough energy to do so, at the same time he did not disclose how closer to death he was in this operation.

Kuroto said to Itachi, “Shisui’s current state is very weak, let’s not talk about missions, Shisui won’t even be able to fight or defend himself in this period, if the enemy were to notice this weakness of Shisui, they will definitely take advantage of it, so I am assigning you the mission of protecting Shisui until he fully recovers. You are to stay by his side all the time and make sure that Shisui remains safe, understand?”

Itachi quickly nodded, “Understand captain.”

Then Kuroto said to Shisui, “Make sure to follow the training regimen I gave you and do not overexert yourself for the next month, until you are fully recovered, additionally, don’t forget to send me daily reports regarding the changes in the body and eyes that you experience, this data will be very crucial.”

Shisui nodded, “Don’t worry Kuroto-san, I will keep it in mind.”

Then Shisui with the help of Itachi went to his home, and Kuroto also went in the direction of his home, but not before making sure that no traces of the secret laboratory being present here were left after that short accident.

On his way home, Kuroto also felt that he was unusually exhausted today, but fortunately, Shisui successfully survived the operation. Compared to this result his fatigue was not worth mentioning.

Reaching home, Kuroto ate a random cup of Ramen, and while lying on the bed he thought of his next move.

Most importantly the next Clone he should focus upon.

The pair of Eternal Mangekyou Sharingan in Shisui’s body did not evolve into the Rinnegan, however, the visual prowess increased a lot. Additionally, with the mastery of ‘Enton: Oshihomimi’ the requirements of the standard Fire Chakra Clone are finely progressing and this clone will be complete sooner or later.

The progress of Water Clone too is on the right track when Kuroto completely masters Sennin Mode with the Suijin Clone, the strength of Suijin Clone will be nothing to scoff at. Then there is also ‘Okami Mode’ and ‘Kuraokami Mode.’

Kuraokami Mode was inspired by the ‘Yamata no Jutsu’ of Orochimaru, and it certainly is a nice Jutsu to battle Bijuu Class opponents.

Overall, Kuroto doesn’t have to focus much on Water Nature Clone and Fire Nature Clone aside from the continuous training, so now he must direct his attention toward the third Clone.

Which Element to choose, and whose Cells to use for the Clone becomes the next major issue Kuroto must focus his attention on.
