Konoha Medical Department, Kuyukina studied here with Tsunade.

Jiraiya's disciple Mizumon walked on the bright avenue and bloomed, Orochimaru's disciple Ye Zi dedicated himself on the dark path, and Tsunade's disciple Ku Yukina took a back seat and concentrated on medical knowledge.

The famous Sanninja disciple keeps improving and strengthening himself in different ways.

Jiraiya has no interest in the Hokage's position, but he thinks that Watergate is very suitable for being a good Hokage, so he is using his influence to pave a bright road for Watergate.

Orochimaru used to yearn for the position of Hokage, but with the experience of these years, the mind of being the Hokage has faded, and now he is more inclined to the research and development of forbidden arts, as for the opportunity to become the Hokage, he will also fight for it, after all, there are many conveniences in the position of Hokage.

He devoted himself to research, unlike Zilai, and let Ye Zi grow and move forward on his own, but if Ye Zi encountered obstacles, he would not sit idly by.

Like Orochimaru, Tsunade is focused on medical treatment, her boyfriend Kato is aiming to become the Hokage, and she wants to be the popularity and effectiveness of a medical ninja to become Kato's backing.

If it weren't for Kuyukina's talent, which is perfect for a medical ninja, Tsunade wouldn't have wasted too much time betting on one person.

In fact, Tsunade has to admit that at a time when a lot of medical ninjas need to be trained quickly, it's worth spending time on Kuyukina.

The Nine-Tails Pillar Force, the Vortex Clan's super vitality, the amazing chakra control, and the same explosive violence have too many characteristics for Tsunade's appetite.

Seeing Kuyukina grow up step by step, Tsunade sometimes has the illusion that the front wave is dying on the beach, and at the same time, she is relieved that she is not the only pillar in Konoha.

In the exclusive room of the medical department, there is a workbench on which a black cat is lying unconscious.

Kuyukina's index finger was wrapped around the pale green chakra, and she gently stroked the wound on the black cat's abdomen that was not thin but not too thick throughout the abdomen, and the speed was not hurried or slow.

With a flick of the index finger, the wound healed at a speed visible to the naked eye, and in just ten seconds, the long wound had healed.

"Whew."

Kuyukina exhaled softly and removed the chakra that was wrapped around her index finger alone.

"Master, how is it?" Kuyukina looked at Tsunade on the side with a smug expression.

"Very good." Tsunade smiled slightly, giving the most correct evaluation, with Kuyukina's chakra control, becoming the strongest medical ninja in the future is just around the corner.

"Hey, hey."

After receiving the master's compliment, Jiu Xingna laughed happily, then gently picked up the black cat, gently stroked the black cat's head, and then softly apologized, and then put it on the windowsill.

"Master, I would like to ask a question." Kuyukina walked back to the workbench.

"You say." Tsunade looked up.

"What causes a young man's hair to start turning gray?"

"Huh?" Tsunade met Jiu Yukina's serious expression and did not answer immediately, because this question instantly reminded her of Ye Zi.

"Can you tell me why I'm asking for that?" Tsunade looked at Kuyukina with interest.

"It's just curiosity." Jiu Xingna hurriedly turned her gaze away, her neck slightly reddened.

"Yes." Tsunade let out an inexplicable laugh.

"Master!" Jiu Xingna was suddenly unhappy.

Tsunade stopped laughing, and said, "Okay, what you want to ask about is Ye Zi's situation, right?" ”

"Hmm!" Kuyukina replied quickly.

Tsunade said softly: "His body is very special, one of the characteristics is that he has strong vitality and fast wound healing, do you remember the day when Ye Zi was dying?" ”

Jiu Xingna nodded heavily, how could she forget that night, how could she forget the appearance of Ye Zi when she was lying on the trunk of a tree covered in blood, that scene had been deeply rooted in her heart.

"The speed of wound healing, which strengthens the vitality force, is one of the characteristics, but he is not a thousand-handed clan, nor is he a vortex clan, and having such a trait comes at a price."

Jiu Xingnai's expression tightened, and said, "Is that the price?" ”

"That's right." Tsunade said calmly: "That's just the superficial price, with the development of strength, Ye Zi's body will speed up this process, which can bring him many benefits, the price is the accelerated death of cells in the body, which will lead to the loss of life." ”

Kuyukina listened very carefully, as if she wanted to peck every word Tsunade said into her head, she opened her eyes and asked expectantly, "Is there a solution then?" ”

Tsunade looked at Jiu Yukina with an expectant face, nodded slightly, but was thinking in his heart: Ye Zi, you are really a lucky guy, there is such a person who cares about you.

"Great." Jiu Xingna couldn't help but cheer, and then couldn't wait to ask, "Master, what's the method?" ”

Tsunade smiled helplessly, held up two fingers, and said, "First, seal, and second, use the cells of the Thousand Hands or Vortex Clan to integrate into Ye Zi's body, but I can be sure that the first method is unrealistic. ”

"How could that person possibly agree to the first approach. I was saved by him, and in order to repay him, I thought about using the first method to help him solve this problem, but now I think about it, it's a bit ridiculous. ”

Even Tsunade, who had less contact with Ye Zi, could see Ye Zi's pursuit of power, and she could see that naturally more people would see this.

Jiu Xingna suddenly raised a happy smile, and she sincerely thanked her bloodline.

Cells of the Vortex family.

Tsunade saw through Kuyukina's mind and struck: "The second method is still just a theory, and it is not so easy to reach the level where it can be practiced. ”

At this time, Tsunade didn't know that this theory, which was just thought up to help Ye Zi, had been perfected by an existence she didn't know, that person was very young, and the possibilities he had in the future were no less than those of Jiu Yuina.

Moreover, after repeated defeats in the integration plan, he was able to believe in the strength of the Ye Zi cell, prompting him to deliberately ignore the strength of the cells between the thousand hands column, which led to the transformation of status, not the fusion between the cells, but only unilateral devouring.

This initiative is absolutely impossible for Tsunade to complete, no matter how active and special Ye Zi's cells are, it is impossible to surpass the cells of her grandfather who she admires and respects, this is the mindset.

"No matter how difficult it is, I want to make this theory a reality." Kuyukina looked confident.

Tsunade didn't say anything, and she still didn't say a word, that is: If Ye Zi doesn't improve as soon as possible, he won't live to be thirty years old, and this is based on not being seriously injured.

In the past, Tsunade maintained a minimum of hostility towards Ye Zi, because a village with a mature system would not accommodate a large clan with the same system.

Later, Tsunade thought the idea was ridiculous, so she gave it up, and after that, she felt that Ye Zi was actually very pitiful, although she had a special body, she could only passively accept it, and passively bear the price, rather than being able to control it herself.

If Ye Zi came to ask her, she would help, and that time she offered to help, but she was rejected, and then she gave up her mind, and now with Jiu Xingnai, she may be able to solve it.

Suddenly, Tsunade thought of something.

The reason why Jiu Yukina tried to learn medical ninjutsu was also for Ye Zi......
