People are in Konoha, scientific achievements are followed by blood

In the days that followed, Tsunade and the others, armed with Yayoi's 'living radar', continued to engage in guerrilla warfare with the enemy.

At the same time, he also teaches Yayoi medical knowledge as well as ninjutsu and taijutsu as leisure activities.

The medical ninjutsu that Tsunade taught Yayoi was Konoha's latest developed "palm ninjutsu".

With Shinato in front of her, and the fact that the Uzumaki clan has such a good relationship with Konoha that she wears a pair of pants, Tsunade has completely regarded Yayoi, a distant relative of the same clan as her grandma, as a Konoha person.

"The palm ninjutsu is a medical ninjutsu recently developed by the village. Although the rigid learning conditions are B, the actual application of the palm ninjutsu is an out-and-out A-level ninjutsu."

Tsunade used Yayoi's body as the subject of the technique, held his left ring finger, and demonstrated to him the release process of the Palm Senjutsu.

"However, since you can learn the Shadow Clone Technique, you are qualified to practice it."

From Yayoi’s perspective, you can see:

First, a chakra similar to the body's energy was released from Tsunade's palm, covering the entire surface of her palm.

Then, the nature of the chakra began to slowly change.From the original chakra of Tsunade, it became more and more like Yayoi's chakra.

Then, this chakra seeped into Yayoi's fingers, controlling him to bend his fingers involuntarily.

Tsunade actually taught him Palm Senjutsu for two purposes. One was to enhance Yayoi's life-saving ability, and the other was to see how high his talent for 'jutsu' was.

Palm Senjutsu is an unprinted ninjutsu, and the teaching process is simpler than other ninjutsu.In a sense, this type of jutsu is more suitable for people like Yayoi who don't have much knowledge of ninjutsu to practice.

Yayoi silently reviewed the process of performing the surgery that she saw in her mind's eye, and began to try to recreate it.

Seeing that Yayoi was deep in thought, Tsunade was afraid of damaging his enthusiasm, so she added:

"Well, it is still very difficult for beginners to learn this technique. Even in the village's medical class, there are not many people who can use it. Just take your time..."

At this point, Tsunade suddenly widened her eyes.

I saw a thin layer of chakra slowly pouring out of Yayoi's right palm, clumsily but firmly wrapping the entire palm, and then changing the nature of the chakra just like Tsunade.

"Does this count as success?" Yayoi stretched out her right hand and showed it to Tsunade.

"Of course, this is just the preliminary stage. This level of Palm Immortal Technique can only be regarded as a B-level technique..."

Tsunade flipped her bangs, hiding her frightened expression, wanting to dampen Yayoi's 'arrogance' and make him take his master's opinions seriously.

"I always feel that the effect of this technique is more than just that..."

Ignoring Tsunade's little tricks to maintain her dignity as a teacher, Yayoi seemed to have discovered something again, muttering to herself, but the technique in her hand had undergone subtle changes.

The chakra representing palm senjutsu extends upward from the palm, wrapping around the forearm, then the elbow, and upwards to the shoulder...

"This kid is a monster!"

Tsunade stared blankly at the 'Palm Senjutsu' coat that gradually wrapped around Yayoi's body, and such a somewhat rude term came to her mind involuntarily.

Orochimaru on the side had brilliant eyes, and he took the initiative to explain to Yayoi:

"Yayoi, you have to know that the development of most jutsu is based on the two changes of chakra "form" and "property". Palm Senjutsu is such a rare combination of "form change" and "property change" The Muji Ninjutsu. "

"In order to reduce the difficulty of using Palm Immortal Technique, the village removed its original ability to change its form and weakened its ability to change properties, thus forming the current Palm Immortal Technique."

Orochimaru glanced at Yayoi's palm senjutsu coat and said with a hint of amazement: "And what you are doing now is to restore the original appearance of this jutsu. And this original palm senjutsu..."

Orochimaru glanced at Tsunade who was a little dissatisfied with his own nosy, "Probably only the woman in front of you has mastered it."

"Of course! No one knows palm magic better than me!"

In order to maintain the dignity of her master, Tsunade resisted the urge to punch Orochimaru and said confidently:

"The Palm Senjutsu is a general-purpose ninjutsu with strong user characteristics. It exhibits different effects depending on the user's medical knowledge and chakra control ability."

While Tsunade casually demonstrated the use of her Palm Senjutsu, she explained to him the origin of this technique:

"The reason why this technique is called "Palm Immortal Technique" is not just that the technique is released by the palms, but because this technique simulates the function of the human body's 'palm'. "

"As Orochimaru said, in order to reduce the difficulty of using the technique, the village used the hand, the most delicate control part of the human body, as a breakthrough point to transform the abstract control of chakra into image control like controlling the palm of the hand, and then from The hands of chakra enter the injured body to repair damaged body tissues."

"Using Palm Immortal Technique can be divided into four steps: "release", "synchronization", "invasion" and "control". "

“Among the four steps, the biggest difficulty lies in the two steps of “coherence” and “control”.These two steps require extremely high chakra control capabilities, especially the latter, which also depends on the user's level of medical knowledge. "

At the same time, Tsunade warned him seriously: "Once the user's chakra control ability is insufficient, or the level of medical knowledge is not up to standard, the chakra originally used for treatment may harm the injured."

"This also means that palm ninjutsu has the potential to develop into offensive ninjutsu."

Orochimaru on the side suddenly interjected and said, seeming to lead Yayoi to this line of thought intentionally or unintentionally:

"The chakra coat you constructed already has the prototype of an A-level destructive ninjutsu."

"Orochimaru!" Tsunade shouted, dissatisfaction in her beautiful eyes: "Don't teach Yayoi to use medical ninjutsu as a murderous weapon!"

"Well..." Orochimaru turned and left nonchalantly:

"In this war, doesn't saving people mean killing people? Why should we make such a distinction?"

Hearing this, Tsunade was stunned for a moment and felt a little depressed for a moment.

At this time, the Second Ninja World War has reached a critical moment. In order to prevent the war from spreading to the country, the Kingdom of Fire and the Kingdom of Wind decided to open the adjacent Rain Kingdom as a battlefield.

In response, the leader of Amegakure Village, "Sansho Hanzo", resolutely declared war on the major powers that invaded his territory.

At this time, they were no longer at the border of the Land of Fire where they met Yayoi, but deep into the hinterland of the Land of Rain.

Their enemies are no longer the invaders of the Kingdom of Wind, but the defenders of the Kingdom of Rain.

In other words, they changed from the protectors of justice to the invaders of evil.
