The strongest technician of Muye

In the evening, the hospital director's office.

"Kakashi, I heard that your Mudu experiment has been successful?"

Tsunade, who was checking the work of the three, suddenly asked.

"Yes, sister Tsunade, the first successful Mudun experimental subject has been taken away by three generations of adults, saying that he will personally accept him as a disciple."

"Oh, the old man has a good calculation."

When Tsunade heard this, he was a little disdainful.

The thirty-two clansmen who died because of Mu Duan's experiment before have always worried her.

The Thousand Hands clan, which had suffered heavy losses in previous ninja wars, now only some old, weak and sick remained!

If it weren't for his own disciples to propose a safer plan, I was afraid that if the experiment was not successful, the Thousand Hands Clan would be extinguished!

"Kakashi, since the Mudun experiment has been successful, you should return to the hospital for internship in the future."

Tsunade went on to say, after all, no matter how strong the theoretical reserve is, it will not be possible to become an excellent medical ninja without a lot of practice.

"That, sister Tsunade, I have already made an appointment with Lord Orochimaru, and I will follow him systematically to do scientific research."

Kakashi scratched his head, his expression a little embarrassed.

"Huh? Don't forget whose disciple you are!

Tsunade turned to look at Kakashi in a stern tone.

"That's a must. Sister Tsunade, you are my own master!

"Hehe, I just want to learn the big snake pill-sama's set of things and use them in medical research."

Kakashi, who is a two-life man, has a strong desire to survive.

"Well, that's pretty much it."

Tsunade nodded, sensing Kakashi's still decent attitude, so he didn't think about him anymore.

Kakashi was secretly relieved that this level had finally passed smoothly.

After a long time together, he and Tsunade already had the feeling of brothers and sisters.

Tsunade's demands on him also became stricter, for fear that he would go astray.

Therefore, it is reasonable that he hopes that his approach will be approved by Tsunade's sister.

After class, Kakashi took Rin to eat tricolor balls as usual, and since the evening class, it had become a habit for them to eat snacks every night.

As for Obito, after understanding the current situation of the Uchiha clan and after more than two years of training by Kakashi, he is now more urgent to improve his own strength, so this point is generally at the training ground.

And Kakashi and Rin would always pack a late-night snack to send him over.

"By the way, Rin," sitting in the beautifully decorated three-color ball shop, the atmosphere here always reminded Kakashi of the dessert shop in front of the school in his previous life, "Did you learn the Yin Seal that Tsunade's sister taught before?" "

Not yet~" Rin, who was holding a three-color pill in one hand, replied vaguely, "The sealing technique of the Yin Seal is too difficult, and it is estimated that it will take half a year to succeed." "

It's not that Lin isn't talented enough.

In fact, for her under the age of 8, the difficulty of learning the Yin Seal up to S level is really superb.

"In this way, then tell me when you succeed, maybe I can let you quickly [create regeneration]."

Kakashi glanced at the 82 points he had saved, and silently calculated the time it would take to collect 100 points.

"Really!"

Rin looked delighted.

The trust she had cultivated over a long period of time made Rin never doubt Kakashi's words, even if it sounded incredible like a quick S-class ninjutsu.

Looking at Rin who was full of expectation, Kakashi's eyes curved into a crescent.

"Don't get excited, eat slowly, don't choke."

Kakashi said, handing the juice to Rin.

"Uh-huh."

Looking at Kakashi's slightly spoiled eyes, Rin's little face blushed slightly.

Since she and Kakashi studied medicine together, the relationship between the two seems to have changed subtly and become more intimate.

Kakashi noticed this as well.

Unlike Kakashi, who ruthlessly rejected Rin in the original work, when he first came to this world and was deeply panicked and uneasy, it was Rin who first entered his heart and lit up the light.

Over time, this warm and sunny girl has gradually become an indispensable part of his life, and even the reason why he rushed to worship Tsunade was because he wanted to find a way to rewrite the tragedy of Rin's death.

Therefore, he naturally will not know that Obito likes Lin like the original work, and deliberately avoid Lin's emotions.

Feelings are such a thing, and they are about two loves.

There is no such thing as whoever loves to die and live, who is more qualified to be with someone he likes.

What's more, Obito in the original work did not think of resurrecting Rin after learning about the ability of reincarnation.

On the one hand, under Madara's guidance, he is already full of despair for this ninja world full of death and war.

On the other hand, Rin, who already liked Kakashi and voluntarily sacrificed for the benefit of the village, would not agree with his approach even if he was resurrected, and stayed with him.

Therefore, Obito hopes to create a world where Rin and Rin also likes him, and forces everyone to accompany him to have so-called beautiful dreams without asking others if they want to.

"Kakashi, Kakashi." Rin waved her little hand in front of the stunned Kakashi to wake him up, "The boss has already packed up, we should go find Obito!" "

Oh, okay."

Kakashi, who had come back to his senses, also stood up and walked with Rin in the direction of the training ground.

On the training ground of Konoha, a teenager in a sportssuit is using the chakra of his feet to stick to the branches and make a curly belly upside down.

"Obito!"

Rin smiled and waved at him.

Obito heard Rinchi's call, landed dashingly, and came to Rin.

"Give, this is the three-color balls that Kakashi and I helped you pack, eat them while they are hot."

"Hmm!"

Wiping the sweat from his face, Obito took the supper in Rin's hand and sat happily cross-legged on the ground.

"I'm going!"

Obito clasped his hands together and ate the warm three-color balls beautifully.

Lynn took out a handkerchief and wiped her sweat with Obito.

Kakashi didn't mind this, he knew that Rin had always regarded Obito, who had lost his parents since childhood, as family, and the friendship at this age was even more innocent and beautiful.

Obito looked a little embarrassed, but fortunately at night Rin couldn't see the redness on his face.

"By the way, Obito, how did you practice before letting you use the maximum amount of chakra and compress the volume of the Hao Fireball to less than half?"

Patiently waiting for Obito to finish eating, Kakashi asked.

"Haha, that's naturally a success, I'll show you now."

Obito wiped his mouth, got up and took a few steps to the side.

"Fire Escape Hao Fireball Technique!"

Obito sealed his hands and took a deep breath, and a solid, one-man-tall fireball erupted from his mouth, illuminating the entire training ground in the dark night!

"Good, the next step is to compress the volume to another quarter."

Kakashi nodded in satisfaction.

"Huh? You still have to compress it, it's not easy to compress it by half!

Obito pouted when he heard this.

"Yes, according to my speculation, when you compress the volume to a quarter, the power generated by its high-temperature explosion will reach the standard of B-level ninjutsu."

"In the same way, if you have mastered this technique, you can also increase the power of [Fire Escape Phoenix Immortal Fire Art] to level B, and the consumption of Chakra is lower than using Grade B Fire Escape directly."

Kakashi explained seriously.

This is the conclusion he came to after repeated verification from his uninterrupted special training.

"So strong?"

Obito seemed eager to try.

Like Rin, Obito has become accustomed to trusting Kakashi's judgment over the course of a long relationship.

After all, until now, he hadn't missed it.

"Yes, the power of ninjutsu used by people of different strengths is completely different."

"On the one hand, there is the difference in the amount of Chakra, and on the other hand, the degree of mastery of Chakra is different."

"For example, the senior Uchiha I mentioned to you earlier, the [Fire Escape Hao Fire Extinguishing Extinguishing] he used can even reach the power of S-level ninjutsu!"

Hearing this, Obito, who was full of anticipation, immediately ran to the side to continue training.

And Kakashi also turned his head to face Rin.

"Rin, your control over the water attribute Chakra now is far beyond the level of ordinary water ninjas, and I will teach you a defensive ninjutsu, [Water Formation]."

"You learn it first, and then try to turn it from a wall of water to a four-sided surrounding."

"Optimistic, Yin-巳-Zi-巳-Yin, Water Formation!"

I saw a wall of water rising from the ground in front of Kakashi, protecting him and Rin behind.

"I am currently mainly practicing the control of wind and thunder attributes, and Shui Dun is only barely able to use it, far from your control. So this training can only be done by yourself.

"Don't worry, I'll make it!"

Rin clenched her little hands, full of fighting spirit, the water attribute control training arranged by Kakashi before had benefited her a lot.

After arranging the training project of the two, Kakashi also came to the side and continued the research and development of the Thunder Attribute Attribute.

As usual, the three of them practiced late into the night again, and this pattern of high-intensity training has long been commonplace for them.
