Naruto: The Strongest Sage.

Yumi's Wood Release was so strong that she couldn't control it in a short period of time. This was normal because she had not received enough ninja training and had no idea about ninjutsu itself. It was indeed a bit difficult to directly control the bloodline limit of Wood Release.

But Aoba was still a little jealous privately. Although he said on the surface that he didn't care about Wood Release, he was talking about Yamato's Wood Release that was used for greening.

Look at Yumi. The effect she produced accidentally is comparable to Yamato. If it is developed, it won't reach the level of the first generation, but it feels not much different.

It was a lie that he said he didn't want this kind of Wood Release!!! It was a pity that he didn't have that kind of luck.

The laboratory is gone, and there is no hope of rebuilding it in a short time. Although Aoba's laboratory is not big, the things used in it are all top-quality goods equipped by Orochimaru.

If those experimental instruments were purchased from the market, they would cost at least 200 to 300 million taels. But Qingye's entire fortune was less than 10 million taels.

His ninja tool shop has been doing well recently, but he won't be able to rebuild his laboratory in two or three years.

Therefore, Aoba could only temporarily suppress the idea of ​​rebuilding the laboratory and focus his limited energy on Yumi and Karin.

Karin hadn't changed much since she woke up from her coma. Her chakra increased again, but she couldn't use the Diamond Seal on her own initiative.

Kakashi and Aoba spent a lot of time researching this, but in the end they had no clue. They could only infer that Karin was too young and using the Diamond Seal would put too much strain on her body.

Last time, she only used a chain for a few minutes and was so tired that she fainted for a whole day. Therefore, her body may have developed a sense of self-protection, limiting her from using this power now.

After this experience, when she grows up, she should be able to perform the Diamond Seal naturally.

Then there is Yumi.

Having obtained such a powerful Wood Release, Yumi naturally needs to master this power as quickly as possible. But in reality, this is a bit difficult.

Because of the special nature of Wood Release and Yumi's weak control, there was no suitable training ground in the entire Konoha.

The woods and riverside areas within the Konoha barrier were all under observation by the Third Hokage's telescope technique. Aoba couldn't take the risk of letting Yumi train under their noses.

If you go out, you need to register. It's not impossible, but if you do it too frequently, it will still attract the attention of others.

After the three of them discussed for a while, Kakashi finally gave a suggestion.

"In fact, I think your previous suggestion is very good, medical ninjutsu. This is one of the few ninjutsu in Konoha that anyone can learn as long as they want to. The simplest medical ninjutsu also requires very high chakra control.

Let Yumi learn medical ninjutsu to train her chakra control. With time, she will eventually adapt to her own strength. "

"It seems there is no better way for the moment." Wood Release, especially Wood Release of this level, would be a big trouble once discovered by Konoha.

Qingye had no intention of destroying Konoha, and at the same time, he did not want to defect for the time being. He still had things to do here. So, it was better to be careful.

However, the number of medical personnel alone is not enough to make full use of Yumi's new body.

The body she obtained from this fusion was many times stronger than Qingye's.

A simple comparison shows that Aoba has obtained a body close to that of an elite ninja from the Uzumaki clan. The chakra amount, physical strength, and recovery ability are all similar. It can be considered as one of the top ninja bodies in the world.

But Yumi's body was matched with Senju Hashirama's. At that time, Senju Hashirama's cells proliferated wildly, almost covering most of Yumi's cells.

In the end, Yumi relied on her spirit and will to forcibly master this power. Even if the cells proliferated, they may not be as powerful as the original Hashirama cells.

However, Aoba deduced that if the power of Yumi's current body was fully released, it should be able to reach 50% to 70% of the level of Hashirama Senju.

It is no exaggeration to say that if Hashirama Senju had 70% of his strength, he could almost destroy the current ninja world as long as Uchiha Madara did not revive. Even Nagato with the Samsara Eye would dare to confront him head-on.

However, if Yumi wants to reach that level, it will take a lot of time to train her.

Her first goal at this stage is for her to initially master the Wood Release technique in her body.

At the same time, Aoba began to give her various basic ninja training, such as climbing trees, treading water, and physical skills. But before she mastered the wood escape technique, he did not dare to let Yumi learn ninjutsu.

The main reason was that they were afraid that she would accidentally cause the advent of the Wood World and submerge Konoha.

After Yumi is able to initially control her power, she will begin real advanced training and learn the Wood Release Ninjutsu of the first generation.

But there is still a small problem here, that is, neither Aoba nor Kakashi knows the Wood Release Ninjutsu.

"Konoha's Sealed Book should contain all Wood Release Ninjutsu. It can be exchanged for points."

"Don't consider this plan. It's too conspicuous. If we dare to choose it, it will definitely attract attention. Sarutobi Hiruzen still has to have some dignity, but if Shimura Danzo finds out, I will have no choice but to kill him."

"...I was just about to say that Shimura Danzo also has information on Wood Release. But you're right, that person is not trustworthy."

"Let's talk about this later. If it doesn't work out, I'll make a deal with Orochimaru."

Kakashi felt very strange about Aoba's choice, because he found that, in Aoba's opinion, Orochimaru's priority was higher than Shimura Danzo's. However, Orochimaru was the traitor, the wanted one.

"Haha, how should I put it. Orochimaru is a dangerous guy, very dangerous. But he is also a very pure guy.

He has his own pursuits and is willing to pay a price for them. So, if you trade with him, as long as you can ensure that you have the capital to trade, then everyone will be happy.

But Shimura Danzo is different. This guy wants everything but doesn't want to give anything. The best way to make a deal with this guy is to kill him when he shows his chips and then take his chips. Because he will do the same thing. "

"Okay, I can't help you with this problem." Kakashi said that he was powerless and Aoba should handle it himself.

At this time, Qingye thought of something. It had been more than a year since he was promoted to a jonin. He had completed a lot of missions and had accumulated a lot of points.

In theory, these points can be exchanged for ninjutsu from Konoha's high-ranking officials, but Aoba has never used them.

"Kakashi, can the Flying Thunder God of the Fourth Hokage be redeemed with points?"

"......" Kakashi looked at Aoba with a strange look.

"You want to learn Flying Thunder God?"

"Yes."

"Then you don't have to exchange it, I can."

"You can?" Aoba expressed his doubt. When would Kakashi learn Flying Thunder God?

"Um, okay. I don't know how to use Flying Thunder God, but I know how to practice it. After all, the Fourth Hokage was once my teacher."
