Although he has the character of a protagonist in a hot-blooded comic, he was not born into a good family. This is the main reason why Fu and Naruto have different circumstances.

Living in Konoha, there are many dangers, but also countless opportunities.

Even a person with mediocre talent like Shuimu was able to survive the initial danger by relying on the "Tiger Curse Seal" that he obtained unexpectedly and whose influence was difficult to distinguish between good and bad.

If you really have nothing and don’t even deserve to be noticed by others, what will you become?

No one can say for sure what has not happened, but Mizuki’s experience in the original work is the best portrayal.

Mizuki pushed these thoughts out of his mind and turned to leave the place.

I have already done my best to help. As for Fu's future, that is Tsunade's concern. Now, there are still some important things that Mizuki needs to deal with.

…

After a fierce battle with Pain, Mizuki and his physical clones were all injured to varying degrees.

For Shuimu, if the injuries did not hit the vital parts, he could easily recover through various means after leaving the battle.

But this time it’s a little different…

The first attempt to use the Byakugan to evolve into the Samsara Eye to resist the Infinite Tsukuyomi failed!

After Xinzhen came back, the abnormal condition of the white eye in her right eye socket became more and more serious. The results of the examination were also very frustrating. In the end, the only way to temporarily alleviate Xinzhen's predicament was to seal the white eye.

"Have you found the reason?"

"The repulsiveness of the Byakugan... No, to be precise, it should be the repulsiveness of the Samsaragan!"

"The Samsara Eye?"

The answer is really surprising.

"Isn't it too early for the Samsara Eye now?"

According to Mizuki's estimation, if he were to forcibly open the Samsara Eye, the amount of chakra consumed would be an astronomical figure. Mizuki even planned to steal the Ten-Tails' chakra to make up for it. Otherwise, if he relied on himself to accumulate it slowly, it might not be enough even after another ten years.

"certainly!"

Xinzhen, who was a little weak, answered weakly.

"But don't forget that the senjutsu chakra that is synthesized with natural energy and one's own mental and physical strength has a manifestation effect. Using the hair that can be controlled freely to perform the diamond seal, gaining the power of the giant bear summoning beast, and transforming into a tailed beast are all related to this characteristic of senjutsu chakra."

"I know that, but there is a limit. If the Byakugan can be activated by Senjutsu Chakra and evolve into the Samsara Eye, it would be a huge joke."

If it were really that simple, the Hyuga family would have unified the ninja world long ago, and there would have been no chance for the Senju and Uchiha to rise.

"Don't jump to conclusions!"

Xinzhen shook his head and answered helplessly.

"Comparing the comprehensive capabilities of the Byakugan horizontally, it is actually not as good as the three-magatama Sharingan. Although the Byakugan is far superior to the Sharingan in terms of detection ability, the increase in both ninjutsu and genjutsu is far less than the Sharingan, so there are physical techniques such as the Gentle Fist. Then how many stages does the Samsara Eye, which is at the same level as the Rinnegan, have to go through to evolve from the Byakugan?"

Shuimu thought about it and was speechless.

"The only one who could evolve to the Rinnegan in one go was the Sage of Six Paths. Even Uchiha Madara had to slowly improve from the Magatama Sharingan, relying on his talent and hard work to sublimate into the Mangekyō Sharingan. By chance, he transplanted the pupil power of his brother Uchiha Izuna's Mangekyō Sharingan, and only then was he able to achieve the Eternal Mangekyō Sharingan. He then took great pains to get the cells of the First Generation, and after decades of nourishment from the vitality of the Outer Path Demon Statue, he was able to achieve the Rinnegan before his death. What exactly does an ordinary Byakugan have to go through to evolve to the Samsara Eye?"

This question is really difficult to answer. Mizuki knows that the Samsara Eye can be synthesized from a large number of Byakugan. There is another method, which is for the Otsutsuki clan to seize the Byakugan of the Hyuga main family and then transplant and synthesize it.

The former method should be feasible, as quantitative change leading to qualitative change is a general rule. However, the latter method is still in doubt. Shuimu has not seen it, so he cannot be sure.

"You mean, the evolution of the Byakugan may also go through the process from the Sharingan to the Mangekyō Sharingan and then to the Rinnegan?"

"This possibility is actually quite high. The white eyes on me are an example of this!"

Two pairs of Rinnegan appeared in Mizuki's memory. In addition to the standard abilities of the Rinnegan, Uchiha Madara's unique eye technique is Rinnegan-no-Mabara, and Uchiha Sasuke's unique eye technique is Tenshūriki. As for the appearance of more Mangekyō Sharingan, there are even more various eye techniques.

The abilities of ordinary Byakugan are all the same, they only differ in strength. This is the result of qualifications and will not change the essence. Sharingan below the level of three magatama are also similar.

"The end point of the Byakugan's evolution may not be just the Samsaragan. There may be intermediate processes or various differentiated branches. Even if the form does not undergo a qualitative change, it is not surprising to have some abilities and signs unique to the advanced form, right? Once it is upgraded to a sufficient level, it will naturally become the Samsaragan, isn't it?"

How could Shuimu know this possibility? There is absolutely no information about this in my memory!

Ignoring Mizuki who looked confused, Xinzhen continued.

"No Hyuga has ever advanced to the Samsara Eye in an orderly manner. The system of the main and branch families prevents them from taking such risks. As for practicing Sage Mode? Well, before we tell them the disadvantages of the caged bird, how could they practice Sage Mode when they still cling to the Gentle Fist? They naturally know nothing about the effect of Sage Chakra on the Byakugan."

"What's your basis for saying that?"

Xinzhen smiled slightly:

"Try using your chakra to probe my Byakugan..."

Mizuki stretched out his hand as he was told, and his chakra slowly probed into the sealed Byakugan.

"Huh?"

"Felt it?"

Shuimu nodded:

"The chakra is being absorbed, a bit like the sealing technique!"

"It's worse than that! As long as the chakra of non-Hyuga people comes into contact with it, it will be absorbed, without exception. Although it will be slow for the time being, it cannot be eliminated actively at all."

If it hadn't been sealed in time, and if the chakra reserves collected by the Breath Containment Technique were not abundant, Xinzhen would have found it difficult to hold on.

"It has eased somewhat after being sealed. As long as you don't use chakra, the abnormality should disappear soon. But if you use Sage Transformation again, the problem will probably get worse."

This forced extraction of chakra from non-Hyuga members cannot be freely controlled like the sealing technique of absorbing chakra.

The situation is already very clear. People with Senjutsu Chakra should not use the Byakugan unless they have Hyuga bloodline.

"After all, unlike the Sharingan and the Samsara Eye, the Byakugan is a completely external bloodline limit, and some situations are really hard to guess..."

Mizuki sighed.

"But why didn't Sasuke's Sharingan upgrade to the Mangekyō Sharingan?"

"In the original work, Sasuke, who had two magatama Sharingan, activated the second state of the curse seal and directly upgraded to three magatama Sharingan. As for the Mangekyō Sharingan and even the Samsara Eye, they cannot be obtained by simply piling up chakra, but the Byakugan can be upgraded by simple fusion, although the amount of chakra required is so great that it makes people despair..."

"I see, this is the difference between skill and strength!"

Shuimu murmured to himself, as if he had realized something.

The end of power - the Samsara Eye and the Tensei Eye are similar, but one is the embodiment of the rules of the ninja world, and the other is a symbol of the conquering power of foreign invaders. Although both have been completely integrated into the ninja world, the difference in their roots is still very large.
