Naruto: The Strongest Sage.

An underground laboratory in Konoha.

Aoba was standing in front of a cultivation chamber. Inside was a young boy, who was Toneri who was undergoing body transformation.

Toneri's transformation is the most complicated one in the entire Otsutsuki transformation plan. The main reason is that this child is not from Konoha.

Although he is controlled by Aoba using Kotoamatsukami, once the completion of the Otsutsuki genes is completed, Aoba cannot guarantee that he will not break free from Kotoamatsukami's control.

After all, in the original plot, although Kotoamatsukami was known as the strongest illusionist, he never really showed his full strength.

Because the original owner Shisui died a long time ago. The first person to use it, Danzo Shimura, was not from the Uchiha clan, and he himself was reluctant to use his eye power.

He controlled a three-ship, but was still seen through.

The other one used was Uchiha Itachi, but he didn't even appear on the field himself, but directly transplanted it onto a crow.

The Sharingan has a very obvious feature. The effects are completely different when used by the original owner, the Uchiha clan, or a foreigner. It's even more so when used by a summoned beast.

Therefore, throughout the original plot, Bie Tianshen did not show any real effect.

In Aoba's time, after he obtained Kotoamatsukami, he perfectly controlled Toneri in full state. But he himself was not an Uchiha, so it is unknown whether he could perfectly exert the effect of Kotoamatsukami.

After Toneri's genes were completed and he became a true member of the Otsutsuki clan, he was not sure whether the other party would break free. Therefore, he needed to add one or more insurances.

After the chakra was separated, he could no longer use the Sharingan. Therefore, Shisui's Kotoamatsukami was eventually given to Uchiha Itachi, who went by the alias Crow.

After all, there might be no one in the entire Konoha who is more suitable for these eyes than him.

Six Paths Sasuke upgraded Kotoamatsukami's Mangekyō to the level of the Rinnegan, and then gave it to Uchiha Itachi. Almost overnight, a combat power close to the level of the Six Paths was created.

It's just that Uchiha Itachi's original body is completely useless. His current body is cloned from the fused cells of Hashirama. Plus, his eyes are not his, so it takes some time to adapt.

This was the reason why he did not fight when Hashirama and Obito attacked before.

Now, he has basically mastered the pair of Samsara Eyes. Qingye brought him to this laboratory just to let him provide a safety net for Toneri.

He might be able to break free from a Kaleidoscope-level Kotoamatsukami, but for one at the Rinnegan level, that's another story.

And it's not just Kotoamatsukami. While Toneri's body was being repaired, the laboratory also did countless things to his body, brain, and even soul to ensure that this top-level combat force was 100% on Konoha's side.

The soul-level operations were carried out under the leadership of Orochimaru.

After arriving in Konoha, Orochimaru even felt a little regretful. He regretted not surrendering to Konoha earlier.

Because only after coming here did he realize the extent to which Konoha's research on chakra, the human body, and genes had reached.

In order to achieve immortality, he needs to constantly use the technique of reincarnation and take over other people's bodies to prolong his life.

But Konoha has been able to transplant brains and achieve another kind of immortality through purely medical means.

Orochimaru had thought of this method before. But his medical ninjutsu was not as good as Tsunade's. At the same time, there was a more important point.

Medical research of this level requires enormous resources, manpower, and reserves of various medical knowledge.

For ordinary ninjas, Orochimaru's reserves are at the ceiling level. However, Konoha's research team has hundreds of them. With Tsunade leading the team, they directly crush Orochimaru in terms of manpower and resources.

Moreover, Orochimaru was wanted by Konoha, and he had to abandon his home and career and wander around for a while every few days.

How could there be any major progress in this kind of environment?

After arriving in Konoha, Aoba had no intention of keeping anything to himself and disclosed most of the information, allowing Orochimaru to completely immerse himself in it.

At the same time, he took out all his research materials without hesitation and compared them with Konoha, which played a huge role in promoting the soul-level research of Konoha Research Institute.

Some of the methods used to target Sheren's soul came from his hands.

At this time, Toneri's transformation was nearing completion. The powerful physical body of the Otsutsuki clan had already awakened him early. However, the moment he woke up, a pair of strange eyes appeared in front of him.
