Tsunade, who is tough by nature but hates war, was entangled by Orochimaru's words. At the same time, she remembered her younger brother who died a year ago, and immediately lost the mood to teach.

Yayoi didn't mean to bother her. In his impression, a woman who was inexplicably entangled was a very troublesome creature.

His choice was to ask Orochimaru, a master of ninjutsu and human body research, and Tsunade did not stop him again.

Orochimaru happily accepted Yayoi's advice.

In terms of human medical knowledge, Orochimaru's research is very in-depth, no less than Tsunade's. It is naturally more than enough to answer Yayoi's questions.

However, when he was teaching Yayoi, he intentionally or unintentionally brought some "private goods" to convey his ideas indirectly, that is, the evil "science" in Naruto.

What surprised Uncle Snake was that Yayoi accepted some of his ideas very quickly, and could even quickly learn from them and propose some research directions that Orochimaru had not considered.

The two of them gradually changed from simple teaching to discussions with a little communication meaning. Of course, Orochimaru was still the absolute dominant one.

Unlike the other two, Orochimaru no longer treats Yayoi as a child, which can be seen from his name.

Among the three, Jiraiya completely regarded Yayoi as a person who needed care, and he was always called "Koyayoi".

Tsunade treated him as a slightly precocious little devil, and he was called "boy" and "Yaoi".

Orochimaru is different. His name for Yayoi has now become "Yaeyoi Jun", and it seems that he has completely regarded him as an adult.

During the communication with Orochimaru, Yayoi's understanding of ninjutsu and chakra was rapidly improving.

Compared with his own memory, Yayoi has a new understanding of medical ninjutsu.

What is different from Tsunade and others is that in Yayoi's eyes, the essence of the sage art is not so much the "morphological changes" and "properties changes" of chakra, but rather the use of another hidden characteristic of chakra, "erosion".

This erosion characteristic of chakra is reflected in many places in anime.

At the chakra level of ordinary mass, this erosion ability is more manifested as "homotorization", "suppression" or "assimilation".

When the mass of chakra breaks a boundary, it will show further "erosion", "transformation" or even "genetics", affecting the spirit and body of the ninja. The blood-resistance limit is the perfect embodiment of this characteristic.

The four steps of the magic of immortal palm are to simulate the erosion of this chakra, which is an application of vitality and body energy. After sublimation to a certain level, it is the so-called "Yang Dun Chakra".

In the four steps of "release", "coordinate", "invasion", and "control", "release" and "coordinate" are carried out in vitro, while "invasion" and "control" are carried out in vitro.

In anime, you often see medical ninjas looking at the injured person with their hands facing green light.

In fact, this is the process of chakra's "release" and "homologous".

Only after the "homologation" is completed can chakra successfully "invade" the injured patient's body, and use medical chakra to "control" the injured body tissues and chakra meridians to achieve effects such as stopping bleeding, removing poison, accelerating self-healing, and physical transformation.

Therefore, we often see a medical ninja's green light masterpiece, which seems to have taken a lot of effort. In fact, only the medical ninjas themselves know how many are fishing and how many are playing a role.

Compared with ordinary medical ninjas, Yayoi's advantage lies in his mental and eye perception ability.

With the help of the perception of the mind, Yayoi can easily analyze the nature of the injured person's chakra, so that after "release" the chakra, he can quickly complete the "homologation" step, so that his chakra "invades" the body tissues and meridian systems of the injured person, and perform the purpose of healing or destruction.

Soon, Tsunade began to allow Yayoi to participate in the rescue of Konoha's wounded. In order to prevent Yayoi from being eager for quick success and instant benefits, she specifically asked: The chakra cannot be used to contact the injured chakra meridian system.

In order to get Yayoi's philosophy closer to him, when teaching Yayoi, Orochimaru often instills some of his own unethical ideas.

He deliberately guided Yayoi to develop the destructive ability of the Palm Skills, and also captured several unlucky enemy ninjas alive with Tsunade and Jiraiya on his back as the destructive experimental subjects of the Yayoi Palm Skills.

Yayoi saw Orochimaru's purpose in his eyes, but did not care much about it.

When his mother Uzumaki died, Yayoi's life began to work hard towards a route: to survive, become a bloody snare, resurrect parents, and rebuild their homes.

For this reason, his bottom line is lower than Orochimaru imagined.

With the contribution of several experimental subjects, after completing the step of invading the human body, Yayoi discovered another secret about his mental and eye abilities.

Originally, from the perspective of the mind, creatures without chakra are clusters of vitality, while ninjas with chakra are a personal outline.

The perception of the mind and eye cannot know the contents of the outline. The inside of the human body is a chaotic whole for the mind and eye.

However, after his chakra further invaded the ninja's chakra meridian system, Yayoi discovered that the perspective of the mind and eyes also expanded to the inside of the human body with the invasion of the chakra, allowing him to clearly see the internal structure of the human body and even the metabolism of the cell as if he were rolling his eyes!

This means that the last step of "control", "the last step of "similarity", is not much more difficult for Yayoi than "homologous".

Yayoi thought for a while and told the discovery, confessing to Tsunade and the other two about their new abilities.

Tsunade and the other three are all very excellent and experienced ninjas, and may be able to give him some advice on mental application.

Upon hearing this, Tsunade was a little surprised and thoughtfully said: he had already banned Yayoi from using the Palm Art to invade the injured chakra meridian system, so how did he discover this characteristic? Could it be...

"Orochimaru, did you let Yayoi on the prisoner..." Thinking of this, Tsunade couldn't help but stare at Orchimaru with his eyes ignited, like an angry lioness.

Perhaps it was Yayoi's age that reminded her of her younger brother when she was a child.

Tsunade has always wanted to keep Yayoi away from the front battlefield as much as possible, and the knowledge he taught Yayoi was mainly medical knowledge and medical ninjutsu.

Therefore, when Orochimaru guided Yayoi to develop the magic of palms in a lethal direction, she was so dissatisfied.

"From today on, you are not allowed to contact Yayoi alone!" Tsunade said angrily at Orochimaru with a gloomy face.

"It's useless, Tsunade." Orochimaru didn't care: "Just like you can't stop Rosaki from participating in the war, what Yayoi carries will make him come to me on his own initiative."

"You guy!" Tsunade clenched her fists.

"Well...well..." Seeing the two of them looking like they were about to fight, Jiraiya hurriedly acted as a peacemaker, "You both are calm!"

As a reckless man who doesn't even know illusion, Jirai didn't know how to practice the magic of palm, and he didn't know that Orochimaru led Yayoi to involve human experiments.

He only knew that his new ability was very good and was very suitable for medical ninjutsu.
