Naruto: The Strongest Sage.

The main research of the institute is still the biological coat made of Hashirama's cells. Once this biological coat is applied to a ninja, it will immediately produce a huge increase in combat power.

Giving it to those elite ninjas can even directly create a Floor Shadow-level combat force.

But because of this, Qingye now strictly prohibits the leakage of this thing. He only keeps improving this technology in the laboratory.

In the entire Konoha, only Aoba, Kakashi, Sakura, and Tsunade have cultivated their own chakra coats.

The rest, even the protagonist like Uchiha Sasuke, did not receive such treatment.

Outside of the chakra coat, Aoba is studying the power of the Sharingan.

Unfortunately, no one else could help him with this research. He could only explore it step by step on his own.

After successfully analyzing the power of the Sharingan, Aoba's next step is to separate and purify the power of the Sharingan.

The complete power of the Sharingan is composed of three parts: Yin Release Chakra, mental power, and spiritual power.

Among them, Yin-Touch Chakra and mental strength form the basis of pupil power. This kind of pupil power is the kind consumed by the one to three magatama Sharingan before the Mangekyō.

And these pupil powers continue to accumulate, and at some point, they will reach a limit.

After reaching this extreme value, the pupil power will undergo a qualitative change through the projection of the power of the mind, thus deriving various incredible effects, forming the various abilities of the Mangekyō Sharingan that people see in reality.

What Qingye needs to do now is to strip away the power of the mind and only keep the purest pupil power.

After several months of testing and analysis, Qingye finally came to a conclusion, or inference. After all, he had no answers to compare, and everything was just his own exploration.

He believes that the reason why the Sharingan is different is because everyone's spiritual power is different. Therefore, the forms of the Mangekyo are different.

At the same time, for some reason, the Uchiha clan has a loophole in their mental power, so the Mangekyo has the weakness of becoming blind if used too much.

There is no difference in the original pupil power, and in theory they can be superimposed on each other. However, the power of mental projection contained in them is different.

This is why the Sharingan's eye power cannot be stacked at will.

However, the kaleidoscope pupil power of the bloodline of the closest relatives can be superimposed. This is also a point that Qingye cannot fully determine the reason for at present.

But he also had a rough idea.

He guessed it had something to do with the body.

Because the power of the mind cannot exist alone. In other words, all the above powers rely on the body to exist.

The power of the body and the mind must be closely connected. The root cause of the defects in the power of the mind that he had observed before was most likely caused by defects in the physical bloodline.

The reason why the kaleidoscope of bloodlines of close relatives can merge is that there is some kind of implicit complementarity at the bloodline or gene level in this process.

This process completes the defects of the physical and even spiritual aspects. In this way, the eternal kaleidoscope appears.

What Qingye needs to do now is to strip away the spiritual power in the pair of Sharingans in front of him, leaving only pure pupil power.

The process itself is not complicated. What is difficult is to find a way to interfere with the power of the mind.

Aoba spent several months in the illusion before he was able to mobilize his mental power to suppress the mental power in the Sharingan.

Once this is achieved, the whole process becomes very simple, because after all, the other person is just a pair of eyes, not a complete person.

Qingye thus successfully separated the pure pupil power.

He took out a sealing scroll and sealed the pupil power inside it. This experiment had come to an end.

The reason why Qingye must strip off the pure pupil power is for his next stage.

He had always had an idea. Bloodline limits were not an absolute bloodline factor. In theory, bloodline limits could be synthesized.

Just like Wood Release can combine chakras of water and earth attributes. It's just that it's extremely difficult to do, and almost no one can do it.

Aoba's idea is that since the blood limit can be synthesized in theory, can the pupil power of the Sharingan be synthesized? In theory, it should be a combination of mental power and Yin-Tsu Chakra.

He had tried before, but couldn't do it. After analyzing it, he found that it contained the personal spiritual power of the Uchiha clan.

This thing obviously cannot be synthesized. Therefore, he chose to strip away the power of the mind, leaving only the purest pupil power, and then re-analyze and try to synthesize it.

But soon, Qingye found that he couldn't do it.

Even though he had stripped off his spiritual power, and even determined the ratio of spiritual power to Yin escape chakra perfectly and accurately, he still couldn't perform the operation of synthesizing pupil power.

Simply put, in his hands, Yin-Touch Chakra and spiritual power cannot be integrated at all. This is not the fusion of two chakras, but two different energies. When operating it, you will find that there is no possibility of fusion.

I can’t even synthesize the basic pupil power, let alone the higher-level pupil power like the kaleidoscope, for the time being.

Qingye's research came to a standstill again. But this time he was not impatient. He even had a feeling that he was very close to the answer. What he lacked now was a flash of inspiration.

After putting his research work on hold, Qingye walked out of the laboratory to get some fresh air.

Sakura has now started to participate in some work at the research institute. It is worth mentioning that she is now a Chunin.

Although she didn't even take the exam, her record of treating hundreds of wounded soldiers still allowed her to advance successfully.

The promotion of a ninja is not based on the results of the exam, but on the ninja's talent shown during the exam.

With Sakura's talent, it would be easy for her to be promoted to Chunin. Of course, others didn't know that this was the effect of the chakra coat.

In fact, for a medical ninja, even if he has the position of a jonin, he cannot use the healing hand hundreds of times in one night.

With this record, she could be promoted directly to Special Jonin. However, she was not old enough and had insufficient experience, so Tsunade decided to play it safe.

"How's the progress?"

Aoba stepped forward and asked Sakura.

"Ah, teacher. The progress is not very obvious at the moment. The activity of the chakra coat is too strong, and the interference with the sealing technique is very obvious. For the time being, it is not possible to use the sealing technique to change the properties of the chakra in it."

A chakra coat with special properties, this is Sakura's current research topic.

Because not everyone, or most people, can have all five attributes. For example, Sakura only has the water attribute.

Yangtun Chakra is acquired through practice, and it can only be flexibly controlled with the chakra coating of Hashirama's cells.

Medical ninjutsu didn't need to be released instantly, so it wasn't a big problem. But combat ninjutsu was far behind.

Qingye was thinking that he could use sealing techniques to interfere with the chakra coat, so that the chakra coat would have its own properties changed.
