Naruto: The Strongest Sage.

Performing a transplant on oneself is actually risky. However, Aoba knows that there is no way to guarantee a 100% success rate for transplanting Hashirama's cells.

He has gathered the three conditions: Hashirama cells, White Zetsu cells, and natural energy as a harmonizer.

For him, the natural energy has an effect somewhat similar to that of the Sharingan.

Danzo also had Hashirama's cells in his body. But his was actually a failure. However, he transplanted ten three-magatama Sharingan into his arm. In this way, he barely suppressed Hashirama's cells in his right hand.

In Aoba's opinion, Danzo's approach was a bit rough.

Hashirama's cells and Sharingan represent Yang and Yin respectively. The true existence of the two should be the intersection of Yin and Yang, mutual promotion and mutual restraint.

But Danzo only knows how to play hardball. Unable to withstand Hashirama's cells, he used the power of Yin escape from the Sharingan to forcibly suppress them. In this way, Yin and Yang only restrained each other, not mutually beneficial, which was really a bad move.

Aoba didn't have the Sharingan. But he had White Zetsu, a special fusion agent that could neutralize the erosion of Hashirama's cells. At the same time, he had unexpectedly discovered that natural energy could actually play a neutralizing role in the fusion process.

This discovery is actually the biggest gain of the entire experiment.

Danzo hadn't discovered it for so many years because there were too few people in this world who could control natural energy. There shouldn't be any roots.

In fact, Aoba deduced a lot of things based on this harvest. Orochimaru's various human experiments in the later period became more and more outrageous. It is very likely because of Jūgo.

Jūgo is a kind of incomplete immortal body. But no matter what, it is all about natural energy. This is probably why Orochimaru's biological experiments are always successful. Natural energy seems to have some special effect. It can act as a kind of adhesive when different biological systems merge.

This discovery was listed as the highest level of intelligence by Qingye because it coincided with a secret deduction he made a long time ago. However, at present, his technology and strength could not reach the essence of those things. Therefore, he could only temporarily seal it and wait for an opportunity to restart the research.

Looking at Aoba's squirming back, Kakashi was still a little bit unbelievable.

"How on earth did you do that?"

"This is a bit complicated to explain. To put it simply, you can understand that I have mastered a method of transplanting primary cells. The success rate is about 50%."

This 50% is the probability without natural energy. Qingye does not want to reveal this secret for the time being. Moreover, he does not have control over natural energy, so it is useless to rely on external forces during the fusion process. Because outsiders cannot grasp the detailed condition of the transplant recipient's body.

Therefore, if you want to use natural energy to neutralize it, you can only master the Sage Mode. If you master it, the success rate can reach about 70% to 80%.

But what Qingye didn't expect was that the fusion process was much slower than he imagined. Because according to the description in the plot, both erosion and fusion were very fast.

But when it came to him, the fusion became extremely slow. But this was not a bad thing. Because he remembered that even Uchiha Madara directly fused Hashirama's cells, and Hashirama's face appeared on his chest.

This shows that such high-speed fusion must have flaws.

On the contrary, Aoba's slow fusion should be that his body completely absorbed and assimilated Hashirama's cells, and combined the strengths of both to rebuild a brand new body.

This is also the reason why Qingye stayed at home and did not go out. This process was not only slow, but also during the whole process, his chakra was almost unable to be mobilized.

That's right, all the chakra in his body was involved in this qualitative change of his body. This also meant that he couldn't use ninjutsu before the fusion was complete.

Of course, his physical skills were still good. In fact, he had already begun to feel his physical strength improving. Moreover, high-intensity exercise was also beneficial to the acceleration of fusion. Therefore, he had been exercising crazily these days.

"So, this is your secret. You completed the first Hokage's cell transplantation all by yourself. What does this get you? Wood Release?"

The reason for transplanting Hashirama's cells is, of course, Wood Release. This was the reason why Konoha started the human experiment.

"Haha. Kakashi, believe it or not, I'm not that envious of Wood Release. What I really want is the first generation's powerful self-healing ability and the chakra that's as huge as that of the tailed beasts. These are what I lack.

As for fighting methods, I am confident that my fighting methods are no worse than any ninjutsu."

"So, you conducted this experiment just to increase your strength? That's all?"

Kakashi couldn't believe it. He was experimenting on himself and transplanting the first generation cells. Was it just to become stronger? Aoba didn't look like a hysterical person.

"Yes, the basic idea is to become stronger. But why do you want to become stronger is the key."

Kakashi was shocked. He had a feeling that the next conversation would be the real key.

"Who do you want to deal with? The Sandaide?" Kakashi knew that Aoba didn't like the Sandaide.

"Haha, forgive me for being blunt, but the Third Generation is not worthy of my plan. I have to deal with an enemy that is ten or a hundred times more dangerous than the Third Generation."

"Impossible, how could there be such a strong person in the ninja world? Even if the third generation is old now, his strength is definitely not to be ignored. How is it possible..."

"That only shows that you know too little about this world, Kakashi. This ninja world is much more complicated and dangerous than you think. The enemy I expected is much more terrifying than the so-called Kage."

............

Aoba had a question, that is, the Konoha high-level officials did not ask him about the Sage Mode.

From this point of view, there is only one possibility, that is, Jiraiya did not report this matter. At that time, Jiraiya should be the only one who could sense the natural energy. If he did not report it, outsiders would naturally not know.

What puzzled him was that he had thought Jiraiya would approach him privately and talk to him or something.

But in fact, Jiraiya disappeared after the Kumogakure incident. He did not return to the village, did not report Aoba's Sage Mode, and did not contact Aoba, as if nothing had happened.

This is what Qingye is most confused about.

At this time, at Toad Mountain, one of the three holy places, Jiraiya was sitting in front of the Great Toad Sage, ready to listen to his new prophecy.

But what the Great Toad Immortal said was a little hard for him to accept.

"The future has become chaos, and I can no longer see the future."
