Naruto: The Strongest Sage.

To what extent will Kotoamatsukami's Mangekyō be enhanced when it is upgraded to the Rinnegan? The original plot does not give any useful clues.

The main reason is that the effect of the other god is a bit too overwhelming, just like the power of God. Even from the beginning to the end, there was no real gathering of a pair.

It was not until Aoba appeared and cultivated Sasuke, a Six Paths-level Uchiha, that the official strongest illusion Sharingan was finally upgraded to the state of the Samsara Eye.

After the Kotoamatsukami Mangekyo was upgraded to the Samsara Eye, it only had one effect, called Tianyu Linghui.

From a simple mental illusion to a deep soul realm, once performed, it can pull the opponent's soul into a space filled with special light, which is the so-called spiritual light.

The spiritual light has two effects, crush and reassemble, and the target is the opponent's soul.

Once hit, the caster can directly crush the opponent's soul in this space. If you don't want to kill the opponent, you can go a step further and reshape the opponent's soul.

After the soul is shattered, it is naturally a blank. Therefore, during the reorganization process, you can freely choose what kind of person the other person will become.

No matter the opponent's muscle memory, mental memory, or soul memory, it will not have any effect. This is a means of reshaping a person from the root.

Simple crushing is fine, but if it involves reshaping. It consumes a lot of energy, and can only be used against one person at a time. But once hit, no matter whether it is Sasuke's Amaterasu or Kakashi's Infinity Domain, they can't resist this soul-level attack.

This ability is a top-level skill that is only used in high-end games. It is similar to the previous Beelzebub. It is almost impossible to use it on soldiers.

After his soul was reshaped, Toneri completely became a brand new Konoha ninja. According to Aoba's instructions, Itachi made a detailed life plan for Toneri, which made him completely become another person.

However, this does not affect Sheren's combat effectiveness.

After completing the Otsutsuki's genes, Toneri's body is now a complete Otsutsuki body.

The amount of chakra contained in it even exceeds that of Hashirama's natural sage body. Moreover, it is born with all six attributes. All it needs is a pair of Sharingan or Samsara Eye to directly have all seven attributes and achieve the combat power of the Six Paths level.

The only regret is that Toneri did not open the Samsara Eye directly. This is actually normal because there are actually few people in the Otsutsuki clan who have the Samsara Eye.

Those Otsutsuki are more keen on using chakra fruits, or elixirs, to open the Rinnegan to supplement their attributes and combat power.

"How do you feel now?"

Aoba asked Toneri.

"It's hard to describe. I can feel that the Byakugan has reached a certain limit. But there's still a little bit left."

"What do you mean?" Sheren's statement was somewhat contradictory.

"Hmm... How should I put it? It seems that this body of mine is... too young."

"..." It was a bit abstract, but the people in charge of this project were all Konoha's top researchers. Soon someone understood the meaning of this sentence.

"Is it that the eyes don't match the body?"

"Not exactly. In fact, I feel very good. There is nothing wrong. This body is young, strong and full of vitality. But it is too young. So, there is a small problem. In fact, even if I do nothing, this problem will be corrected soon."

"I see. It should be the self-protection of the body and eyes. Just like Sasuke's Sharingan opened very late. It is essentially a kind of self-protection of the body. Because the eyes opened too early, the burden on his body was too heavy.

Your current body should be in a similar situation. Normally, you should be at least a teenager before you can open your Samsara Eye. Your body has the relevant memory at the genetic level.

Even if your body has reached the conditions, the body's self-protection mechanism has not yet responded. "

"That's a very accurate description. I just need to move my body around and go through a few battles. I should be able to quickly adapt and activate my Samsara Eye."

"Very good. Let's start with Neji and Hinata as well."

After making the arrangements, Aoba went to the place where Uchiha Madara was in seclusion.

Not long ago, he felt that Madara's chakra fluctuations began to become stronger. Madara took the Farewell and Utopia that Aoba had artificially upgraded. This pair of Mangekyō. He preferred this kind of eyes that directly increased attack and defense.

He also refused to ask Sasuke to help him open the Rinnegan, and instead made use of various research results and resources from the research institute, preparing to open the Rinnegan again on his own.

If someone else said this, Aoba would directly refuse. But if Madara wanted to do it himself, he didn't have any temper. Because the other person had really opened it himself.

The second time Madara tried to open the Samsara Eye, he had a younger body and more chakra than the last time. In addition to the experience from the last time, he also had the full support of the laboratory.

This time the opening was almost smooth sailing.

On the seventh day of retreat, Qingye felt that the power of the Kaleidoscope had reached its limit.

On the tenth day, signs of a breakthrough began to appear.

On the twelfth day, a new chakra appeared in his perception. He knew that Madara had succeeded.

It was much harder than Sasuke's. Because Sasuke first used the Six Paths and then reversed. Reverse was much easier. And Sasuke, who had absorbed all of Aoba's chakra, had a very strong foundation. His chakra was almost infinite, and he was many times stronger than Madara.

After opening, in Aoba's perception, the pupil power was obviously not as strong as Sasuke's eyes. But it didn't matter to Madara, because he opened his own eyes. Therefore, his control of the Samsara Eye was much stronger than Kakashi and Itachi.

"Master Madara, congratulations on your advancement to the Rinnegan."

"Humph, don't think I don't know. This is the fourth pair of Samsara Eyes in Konoha. The legendary Sage's Eyes appear in batches in your hands. You are really special."

"Haha, there are only four pairs, not many. Madara-sama should have some reserve Sharingan in his hands. Just give me some time, I can cultivate more Samsara eyes."

Madara was somewhat speechless. As an Uchiha, he once had a kind of reverence for the Samsara Eye. Although he didn't say it, he was actually very proud of himself when he opened the Samsara Eye by himself.

Unexpectedly, after the resurrection, Madara thought he could sweep the ninja world with the Samsara Eye. However, after a few years, the Samsara Eye was almost everywhere. This gave him a strong sense of unreality.

Four pairs of Samsara eyes, and more to come. Madara has begun to understand Aoba's tactics.
