Naruto: The Strongest Sage.

Qingye's body appeared in a special space. This was the illusion space created by the Sharingan.

It can't be compared with Itachi's reading. This space is extremely simple, and Aoba can't manipulate time and space.

But relatively speaking, this space is not as dangerous as Tsukuyomi. Most importantly, the Sharingan's illusion is activated using Aoba's chakra.

Therefore, he can interfere with this space to a certain extent.

What Aoba needs to do now is to reversely invade the spiritual world of the Sharingan through this illusion space.

Of course, a pair of three-magatama eyes alone cannot be called a spiritual world, but the power it contains is real, and has been successfully activated.

This made Aoba's search for the source of the Sharingan's power much easier.

The invasion process was not easy. Qingye encountered obstacles at the beginning. It was a special mental force that prevented his invasion.

An instinctive force.

Aoba knew that this was the original owner of the Sharingan, and the spiritual power that remained in the Sharingan.

After breaking this power, Qingye entered a peculiar perspective.

The spiritual world itself is different from reality. It is more idealistic, even absurd and bizarre.

Qingye found it difficult to describe the scene he saw. If he had to describe it, he would say that he saw something like a puzzle.

Yintun Chakra, mental power, and some more abstract power together form a puzzle.

Qingye understood that this should be the analysis of the power of the Sharingan. However, in the spiritual world, it was presented in an extremely abstract way.

Qingye could understand this abstraction. The only thing he couldn't understand was that the puzzle was incomplete.

The third abstract force has a noticeable gap, which makes the whole puzzle incomplete.

Aoba realized that he had approached the deepest secrets of the Sharingan.

The Sharingan is extremely powerful, but has a huge flaw.

After turning on the kaleidoscope, you may be strong, but it is really unbearable to be blinded all the time.

Qingye also has a kaleidoscope. Although Kotoamatsukami has consumed a lot of his pupil power, he can still use kaleidoscope-level illusions. But he doesn't dare to use it casually.

Although Hashirama's cells alone can slowly restore his pupil power, the speed is too slow.

As for the operation of opening Susanoo with one eye, he didn't even try it. His Sharingan was too precious. If it was blinded, it would be a bit not worth it.

However, after a deep exploration of the power of the Sharingan, Aoba gained a new understanding of the problem of blindness caused by excessive use of the Mangekyō.

The combination of Yin Release Chakra and spiritual power is the most basic pupil power. The Uchiha clan, because of their blood relationship, are born with the ability to perform this operation inside their eyes.

But that's all, at most you can open the Sharingan to three magatama.

If you want to go further, you need a third force to join in. Aoba calls this force the power of the mind. It corresponds to the name of the mind-reflecting eye of the Sharingan.

It can only be said that although the second generation is not a member of the Uchiha clan, his research on the Uchiha clan is quite in-depth. This description can be said to be very accurate.

Because in Aoba's observation, the last kind of power is the key to triggering the qualitative change of the Sharingan pupil power, eventually transforming into a Mangekyo, and obtaining various magical abilities.

This kind of power is more abstract than the illusory spiritual power. It is the projection of a person's inner subconscious.

Yin-Touch Chakra and spiritual power make up the pupil power. And this power of spiritual projection sublimates and transforms the pupil power, projecting the power that one desires most in the depths of one's heart in reality. In this way, different Mangekyō Sharingan are formed.

But that power of mental projection has certain flaws.

Qingye didn't know why. He guessed that it was because the Uchiha clan, as the descendants of Indra, had an impure bloodline and a natural mental or physical defect.

It is precisely this defect that causes the Kaleidoscope's pupil power to be strong, but the burden on the body is extremely huge.

The intuitive description is that the desired effect of mind projection is a world. However, the pupil power of the eyes can only create an independent small space. The missing ones will be transformed into a burden on the body.

You know, whether it is chakra, mental power, or the final pupil power, they all need to be truly released through the physical body in the end.

From this perspective, if Obito didn't have Hashirama's cells, he wouldn't be able to use Kamui many times. And from this, we can see that although Uchiha cheats, Hashirama's cells are the real official cheats.

In any case, this experiment is of great significance to Qingye. After learning this, he has already thought of many different research directions for the future. However, they all need some time.

He still needs to deal with some trivial matters at the moment.

The negotiations with Sand Village have been going on for a week. For negotiations between two of the five major ninja villages, this is a normal operation.

In fact, Qingye felt that it was still a bit too fast. Because the results were said to be out today. He originally thought that it would take at least half a month.

Although Tsunade is a woman, she has a hot temper and is very decisive. She has no intention of dragging this on any longer.

The Sand Village naturally had to pay a huge price. They had no money for war reparations, but they paid a lot for various secret ninjutsu.

This made Konoha's Sealed Book almost twice as thick.

At the same time, there is also the opening of trade, giving up a large share of missions, intelligence sharing, etc. And most importantly, a military alliance with Konoha.

The contract stipulates that Sunagakure needs to provide military support when Konoha needs it. However, it does not mention whether Konoha will recruit more troops when Sunagakure needs it.

To put it bluntly, this is a disguised subsidiary contract. Since signing the contract, Sunagakure has become Konoha's younger brother to some extent.

Tsunade's dominance is completely different from the easy-going Third Hokage. Without Chiyo's presence, the team led by Maki is no match for Nara Shikaku.

After signing the contract, Maki was in a trance. He even felt like committing suicide right now, because this contract almost sold out Sunagakure.

Tsunade, who had won a great victory, was naturally very proud. After drinking two cups, she went straight to Aoba's house.

"Are you Haruno Sakura?"

"Yes, Lord Hokage. The teacher is not at home." Sakura hurriedly saluted when she saw it was the Hokage.

"Okay, you are Kamikawa Aoba's disciple. I don't remember that guy ever greeting me. And I'm not here to see him this time, I'm here to see you."

"Find me?"

"In the recent war, I heard that you performed the Palm Immortal Technique for a whole day and night, and treated more than three hundred wounded soldiers?"
