In the days that followed, the three generations of Hokage did not use the telescope technique to observe Yamanaka, and Yamanaka's previous performance was recognized by him.

And Yamanaka Yuan spent a week in the library, and in a week, he read all the books related to medical ninjutsu in the Konoha Library, and had a certain understanding of the medical system of the Hokage World.

The medical ninjutsu of the Hokage world is a medical ninja that repairs some cells that can be repaired through special chakra, stimulates cell division and regeneration to replenish the cells that cannot be repaired, so as to achieve the purpose of allowing the wound of the injured person to heal quickly.

Medical ninjutsu also has morphological changes, and through morphological changes, the essence of medical ninjutsu can also be changed to achieve the effect of attack, such as the chakra scalpel.

And the change in the nature of medical ninjutsu, combined with the ninjutsu that appeared in the original book, is currently only the creation and rebirth of Tsunade, and the self-reincarnation of Chiyo's mother-in-law.

As for the rapid recovery and healing of the wounds between the first Hokage Thousand Hands Pillar, in Yamanaka's distant opinion, this is out of the category of medical ninjutsu, and it is the manifestation of the extreme Yang Escape Immortal human body.

However, it is undeniable that the rapid healing between the Thousand Hand Pillars is the basis for the development of medical ninjutsu, and not everyone can have the immortal body, but the healing technique that can be learned through the change of form, the palm immortal technique can be widely promoted.

In this way, later generations learned that the rapid healing of wounds between the thousand hands and pillars was the effect of accelerating cell division, so they repaired the cells through chakra, accelerated cell division, and replenished the missing cells at the wound, and sure enough, the patient's wound healed quickly.

But even the rapid healing between the thousand hand pillars is not unlimited, and there are times of cell division in a person's life.

In the early days of Konoha establishment, Senju Tsuruma and Madara Uchiha fought in the Valley of the End, Senju Tsuruma killed Madara Uchiha, and if it wasn't for Izanagi Uchiha Madara was already dead, it is only said that the result at that time was that Senju Tsuruma won.

However, the victory is also a miserable victory, not to say that this is the plan of Madara Uchiha, but to say that after the battle of the end valley, Senju Tsuruma also died soon after. And the cause of death between the Thousand Hands Pillar Yamanaka is speculated to be a battle with Madara Uchiha, and the number of cell divisions is too much, and even the ultimate immortal body can't withstand such a huge consumption.

And the medical ninjutsu developed on the basis of accelerating cell division between the Thousand Hand Pillars is inherently imperfect in the eyes of Yamanaka Yuan, and the Thousand Hand Pillars with the human body of Yang Dun Immortal cannot allow cells to divide indefinitely, let alone ordinary ninjas.

In the original book, when the Five Shadows vs Madara Uchiha, Tsunade Jiefang Yin Seal continued to stimulate the cells with the accumulated chakra, and opened the forbidden art [Ninja Creation is alive. Baihao's Technique] barely reached the rapid healing of the Thousand Hands Pillar back then.

After the release of Tsunade's technique, not only will the chakra of Baihao's technique be consumed, but the lifespan will also be shortened, and the reason for the shortening of the lifespan is the continuous division of cells during the release of creation and regeneration.

Compared with the medical skills in Yamanaka's previous life, the effect is immediate, and it can be said that both the treatment process and the treatment result are simple and rude. And the biggest disadvantage is that the patient's wound has to be exchanged for his own life.

The world of Yamanaka has a clear understanding of the Hokage's medical system for a week, and the next step is naturally to learn medical ninjutsu.

The basis for learning medical ninjutsu is chakra control, and the secret art of the Yamanaka clan is to improve and control mental power, and the mental power is strong and controllable, so naturally the control of chakra is also extremely good. In the anime, Yamanaka Ino was favored by Tsunade to teach medical ninjutsu for this reason.

Shan Zhongyuan has been a human being for two generations, and he has practiced the family secret art of the mountain clan since he was a child, and his spiritual power is also outstanding in the family.

After dinner, Yamanaka and Yamanaka made it clear that they wanted to learn medical ninjutsu.

Yamanaka Jingzi didn't have strong combat power during her time as a ninja, but she was a special shinobi of Konoha with excellent medical ninjutsu.

Yamanaka is one of the few medical ninjas in Konoha Hospital who can use the [Palm Immortal Technique]. Tsunade has a thousand hands of blood, and the amount of chakra is huge, and the healing effect of medical ninjutsu is much stronger than that of Yamanaka Jingzi, but in terms of the medical skills mastered, there is not much difference between the two.

Yamanaka Jingzi began to teach Yamanaka Yuan Medical Ninjutsu from the basic [Healing Technique].

Yamanaka Jingzi didn't expect her son's talent to be so terrifying, in three days, Yamanaka Yuan had already mastered the basic ninjutsu [Healing Technique] of a medical ninja, Yamanaka Jingzi watched her son use [Healing Technique] to make a fish that was about to die alive again, and her proficiency was almost comparable to that of ordinary doctors in Konoha Hospital.

Yamanaka Yuan has repeatedly practiced and used more than 1,600 [healing techniques] in the past three days, Yamanaka Yuan's ninjutsu talent is actually average, but Yamanaka Yuan's chakra control is very good, and diligence can make up for clumsiness, in addition to eating and sleeping for three days, Yamanaka Yuan has been practicing [healing techniques], and finally can skillfully use the basic ninjutsu of this medical ninja.

[Healing] is actually like the five basic attributes of wind, thunder, earth, water and fire, only with the wind attribute can you learn the ninjutsu of the wind attribute, and learning the [healing technique] is like having the medical ninja attribute.

"To learn the [Healing Technique], the next step should be to add the form change on the basis of the [Healing Technique], whether it is the [Palm Immortal Technique] or the Chakra Scalpel, it is the [Healing Technique] after the form change. Yuan, I'll teach you the palm fairy art first. Yamanaka Jingzi explained the [Palm Immortal Technique] to Yamanaka Yuan in detail.

The cultivation of [Palm Immortal Technique] is not as simple as [Healing Technique], Yamanaka Yuan has not been introduced for more than a month, it is not so simple to add form changes on the basis of a ninjutsu, the original Zhongbo Feng Shui Gate took three years to complete the Spiral Pill, even so, Yamanaka Yuan was still a little impatient, repeating the form changes of [Healing Technique] again and again.

The cultivation of [Palm Immortal Technique] has not been able to enter the door, Yamanaka Yuan can only find inspiration in the original book, he recalled that in the original book, Naruto added the wind attribute nature change to the Spiral Pill, Yamanaka Yuan began to add the sharpness of the wind in the [Healing Technique], Yamanaka is far from having the wind attribute chakra, but he can simulate the feeling of sharpness, and the [Healing Technique] has become a scalpel condensed by Chakra with the injection of Chakra.

"I see!"

What kind of morphological change is added to the [Healing Technique] is determined by the chakra injected by the caster.

Yamanaka Yuan infuses the [Healing Technique] with a soft and warm chakra that feels like warm water. The [Healing Technique] gradually became the [Palm Immortal Technique]. After more than a month of cultivation, I finally succeeded!

"Very well, with the accumulation of experience far from the rest, I have nothing more to teach you."

"Hmm."

After nearly two months of hard work, Yamanaka Yuan mastered the [Healing Technique], the [Palm Immortal Technique] and the Chakra Scalpel in the medical ninjutsu. Combined with his 5 years of surgical experience in his previous life, Yamanaka is confident that at this time, he is very close to Tsunade in the original book in terms of medical ninjutsu.

Early the next morning, Yamanaka decided to go to the ninja school for the first time in a long time.

After the shadow clone is lifted, the memory and experience ontology are all empathetic, and in Yamanaka's distant memory, he gets along very happily with Kakashi, Obito, and Harano Rin. The love triangle in the original book is still a love triangle, the difference is that he has a big light bulb. And these three people have also become one of the few friends in the mountains.

Thinking of these three people, Yamanaka Yuan suddenly looked forward to the ninja school.
