The strongest technician of Muye

Leisure time was always short, and after seven days of vacation, Kakashi returned to the place where he practiced with Tsunade's sister.

"Kakashi, Rin, you're here."

Tsunade looked at Kakashi and Rin in front of him and nodded slightly.

More than two years have passed since Kakashi and Rin first practiced with her.

Now Kakashi and Rin have faded their original youth and immaturity, and faintly have the appearance of professional medical ninjas.

Kakashi's progress goes without saying.

Rin also showed her talent for chakra control.

Through the study of forgetting food and sleep, she has firmly mastered the primary and secondary medical knowledge, and successfully learned the A-level medical ninjutsu [palm cactus]!

You know, the level of ninjutsu is divided by learning difficulty.

Normally speaking, the vast majority of ninjas in the village who can master A-level ninjutsu have the level of upper ninja.

On the one hand, because in addition to the mystic family's own inheritance, the learning of A-level ninjutsu requires enough contribution points to be obtained from the village, and ordinary ninjas cannot reach it.

On the other hand, A-level ninjutsu requires extremely high requirements for the learner's basic ability in at least one aspect.

For example, the prince's signature multiple shadow avatar requires the user to have a huge Chakra reserve, otherwise it is likely that Chakra will be exhausted and die after excessive use.

Similarly, the reason why [Palm Cactus] is only mastered by a few people in the entire Konoha's medical class is because it has almost demanding requirements in the level of Chakra control of the caster.

And Lin, with her amazing talent in Chakra control, coupled with more than two years, has spent almost all of her rest time practicing the precise control of Chakra water masses.

Now she can stitch up the wound while controlling Obito and Kakashi, composed of two Chakra water masses, and perform a physical duel on her shoulder!

This high-end operation with three hands and three uses, even Tsunade was amazed when he saw it for the first time!

Therefore, from the moment Lin learned the [Palm Immortal Art], Tsunade officially accepted him as a disciple.

"After more than a year of continuous study, you already have the basic qualities of a medical ninja, so I will arrange for you to go to Konoha Hospital with Shizune for an internship."

"In the future, you will practice in the hospital during the day and learn advanced medical knowledge with me at night, so that you can apply what you have learned and become a professional medical ninja as soon as possible." Tsunade said to them solemnly.

"Yes, sister Tsunade!"

Kakashi and Rin looked at each other and replied in unison.

"Tsunade, what I said before, do you want to think about it again. The experiment has not been going well, and I need the help of you, who is well versed in human medicine.

At this moment, a hoarse voice sounded, and Kakashi fixed his eyes on the fact that it was Orochimaru who came.

Experiment, Kakashi's heart moved.

After World War II, Konoha, which had already suffered a serious loss of combat power, was stimulated by the further loss of Konoha White Fang, a shadow-level powerhouse, in order to reproduce the glory of the original Hokage, the Mudu experiment was finally opened!

At this time, the Mudu experiment belonged to the high-level organization of Konoha, a legal project approved by the third generation of Hokage.

The Thousand Hands clan who participated in the Mu Dun experiment were also voluntarily dedicated themselves with a strong sense of mission under the influence of the will of the three generations of Hokage Fire.

Unfortunately, because the cells of the original Hokage were too overbearing, the experimental progress so far, there has not been a single successful case.

And the losers have all become big trees!

The Mu Dun experiment itself is confidential.

However, Kakashi and Rin belong to the Tsunade lineage, and their potential status in the village is not low.

In addition, although he is not old, he has a mature mind that exceeds his peers, and his tone is very strict, and he is deeply trusted by Tsunade.

Therefore, except for the first time when the big snake pill came, Tsunade specifically emphasized the confidentiality requirements for the two of them, and when the big snake pill looked for them again, Tsunade did not deliberately avoid them.

"Great Snake Pill, as I said before, although I can not oppose all this for the benefit of the village, I will not participate in such a dangerous thing as experimenting with my people!"

Tsunade frowned, his tone a little disgusted.

As a par medical ninja, Tsunade himself does not reject human experimentation.

On the contrary, she also believes that human experiments are an indispensable part of promoting medical progress, but the premise of all this is that the safety of the experimental subjects themselves must be as much as possible!

And she, who had seen the power of her grandfather Mu Dun with her own eyes, was pessimistic about the Mu Dun experiment from the beginning, because it really didn't look like a power that mortals could control.

Sure enough, the Senju people who were incited by the high-level and sacrificed their lives for the righteousness of the village died one after another, which made her show deep dissatisfaction with the high-level behavior of ignoring the danger of the experiment and enforcing it.

"If you really don't want to, you might as well let Kakashi be my assistant."

Orochimaru licked his lips and turned his words to look at Kakashi on the side.

After being rejected many times, Tsunade's attitude was already well known to him, so Kakashi, who inherited Tsunade's mantle and showed an amazing talent for learning, was the real purpose of his trip.

"Impossible, such a dangerous experiment, I won't let Kakashi participate, don't even think about it!"

Tsunade decisively refused.

"That, sister Tsunade, actually, I want to give it a try too."

Kakashi, who had been watching, suddenly spoke.

"Kakashi, do you know what you will face if you get involved!"

Tsunade jerked into Kakashi's eyes.

She wondered why her disciples were interested in such a dangerous experiment.

Did he also think that the villagers in the same village could be sacrificed so rashly in pursuit of strength?

"Tsunade-sama," Kakashi did not avoid Tsunade's gaze, "Since the experiment cannot be stopped, perhaps I can use my medical skills to reduce the casualties of those warriors who gave their lives for the village."

"Even if it's just a little more chance of surviving for them, it's worth it."

Listening to Kakashi's unscrupulous words, Tsunade fell silent.

Even she had to admit that Kakashi's method was most realistic at this stage when she wanted to protect her fellow students involved in the experiment.

Orochimaru on the side didn't make a sound, but his interest in Kakashi grew stronger.

After a while, Tsunade finally sighed.

"Well, since you have such an idea, I won't stop you. However, every night of higher medical studies, you must participate on time.

At this, Tsunade paused.

"In addition, if you encounter a problem that cannot be solved during the experiment, you can take advantage of the evening class time to ask me questions."

With that, Tsunade waved his hand, signaling that he could go.

"Yes, sister Tsunade!"

Kakashi breathed a sigh of relief, and with Tsunade's sister's statement, he was able to participate in the Mudu experiment and contact the intercolumn cells.

Orochimaru on the side smiled slightly and turned to leave, while Kakashi followed behind him.

"Big Snake Pill, no matter what happens, protect him!"

Tsunade's voice came from behind him.

The big snake pill froze at his feet and did not look back.

These familiar words reminded him of the scene before the rope tree set off.

That time, he failed to bring his beloved apprentice back, and Tsunade lost his own brother ever since.

"Don't worry, Tsunade. This time, I won't break my word. "
