Naruto: The Strongest Sage.

Two days later, Kakashi brought back a message for Aoba.

"This was planned before. Shikaku wanted to ask for your opinion."

Aoba took it and saw that it was actually Karin's early graduation document. As Karin's guardian, as long as he signed the document, it would take effect immediately.

Qingye thought about it for a moment and immediately understood.

"The higher-ups want Karin to team up with Uzumaki Naruto?"

"That's right, I was originally the team leader. But now, as long as you nod, it's yours."

"Haha, interesting. Is this what Shikaku meant or what the Sandaime meant?"

"It should be the result of a discussion between the two of them. Any questions?"

"It's not a big problem. I can only say that this move is very clever. The higher-ups won't be so confident if I lead a team of Jinchūriki.

But if Karin joins, I won't be able to not do my best. And Karin and Naruto are both from the Uzumaki clan, so it's easier to establish a bond. Who's the last one, Uchiha Sasuke?"

"Yes."

"Sasuke has a good relationship with Naruto. He is from the Uchiha clan. After his Sharingan grows up, he can restrain the tailed beasts. Counting me as Karin's guardian, the whole team has a full bond and restraint effect. It's really difficult for the top leaders of Konoha.

Sorry, I forgot that you are also one of Konoha's high-ranking officials. "Aoba's insincere apology made Kakashi feel helpless. He was not very interested in this so-called Hokage advisor.

But after he actually took the position, he found that things were not as complicated as he thought. He had a lot of time to slack off, so he just accepted it.

"By the way, who originally took Karin's position?"

"She is a girl named Haruno Sakura, a pure civilian ninja. But just like you back then, she is very good at theory classes, and she basically gets full marks in all of them."

"If Karin had half of what others have, her mother and I wouldn't have to worry so much about her homework. They will graduate next month, so keep this girl for me and I will ask her if she is willing to be my disciple."

"no problem."

Kakashi could now feel the benefits of being a Hokage advisor, or the benefits of power, from time to time. This kind of small matter did not need to go through Konoha's high-level meetings. With just one word from him, Konoha's teachers immediately arranged everything clearly.

After discussing the business, the two came to the basement again. At this time, Feidan was receiving the transplant of Hashirama's cells.

Aoba made a series of plans for Hidan, and the transplantation of Hashirama's cells was only the first step.

At this time, Hidan's whole body was wrapped in bandages. That was the result of Aoba directly removing all the deformed bodies after the last transplant failed.

And the distortion continued, causing the wounds on his body to not heal.

To be honest, if this happened to an ordinary person, they would go crazy even if they were immortal. But Feidan, the evil god's chosen one, had an extraordinary resistance to pain.

He even said that the Evil God liked this kind of pain and he could hold on for a while longer.

Of course, for Hidan, the evil god can only rank second in his heart. The first is Aoba. As long as Aoba is willing, he can sacrifice himself or even the evil god at any time to make Aoba happy. A little pain is nothing to him.

"For Hidan, the transplant of Hashirama's cells was a failure. And it failed more than once. But the immortality of his body gave him countless possibilities. Now, his body has begun to merge with Hashirama's cells. The process is very slow, and normally it would be unbearable. But he can do it."

Kakashi was a little speechless. He realized that he couldn't catch up with Aoba in this aspect.

But it must be said that although Qingye's methods are cruel, once he succeeds, he will have a super master with huge chakra, immortal body, and even the possibility of knowing wood escape as a subordinate. And the kind of person who is absolutely loyal and willing to die for him.

But these are just the first step in Qingye's eyes.

After Hidan completely merged with Hashirama's cells, Aoba asked him to start training in ninjutsu. Hidan's physique is very good, and he possesses most of the characteristics of a ninja. His weaknesses are in ninjutsu and illusion.

The problem of ninjutsu is easy to solve. Chakra is enough, and you just need to practice hand seals. Feidan has a lot of combat experience, and the timing of releasing ninjutsu is basically self-taught.

As for illusion, Aoba is almost ready.

But Aoba was not satisfied, he had another idea waiting for Feidan to complete, that is the Eight Gates of the Physical Arts.

Just imagine what the result would be if an immortal body practiced the Eight Gates. Aoba was really looking forward to that day. By then, Feidan would become a perfect tool man.

Kakashi still had some work to do as a consultant. He turned around and left.

Aoba continued his other research, the Sharingan.

He now has his own Sharingan. Although Kotoamatsukami has used it, it does not mean that this Mangekyō is useless. Aoba can still use this Sharingan to release illusions and rebound these operations.

At the same time, this Sharingan also made up for the last weakness of Qingye's attributes, Yin escape. In other words, now Shangchuan Qingye has all the seven attributes of Yin and Yang, Five Elements.

Theoretically, he could now try to create the Truth-Seeking Jade, or try to develop his own bloodline network.

Of course, Aoba himself knew very well that these were only fantasies at the moment.

Whether it is the Truth Seeking Jade or the Bloodline Net, they are beyond his reach now. Therefore, his current energy is still focused on the Sharingan.

However, Qingye's research this time was not on the abilities of the Sharingan. His research was more in-depth, and he wanted to analyze the power of the eyes contained in the Sharingan.

Aoba has been curious about this variant of Yintun Chakra for a long time.

The Sharingan has many abilities. Dynamic vision enhancement, illusion enhancement, illusion rebound. After opening the Mangekyo, a super eye technique that echoes the mind photography will appear.

The core energy source required for so many abilities is pupil power.

Eye power is a kind of Yin escape chakra, but it is more than just chakra. Because it has a unique property, the eye power will surge instantly due to the fluctuation of the spirit.

This characteristic is the conventional advancement route of the Sharingan. At least before the Mangekyō, there is no other shortcut.

Based on this characteristic, Qingye deduced that the pupil power of the Sharingan should be a product of the combination of Yintun Chakra and mental power, just like Senjutsu Chakra is a combination of natural energy and Chakra.

Qingye's goal is to reverse analyze this combination, find the synthesis formula, and thus find a way to artificially synthesize pupil power.
