Naruto World does not talk about science, but Ninja

"This is it. Today I will take you to meet the person who gave you those sealing techniques." Senju Tobirama said.

"I understand." Uchiha Taki instantly understood who he was going to see next, Senju Hashirama's wife, Konoha's first Nine-Tailed Jinchuuriki, Uzumaki Mito.

To be honest, Uchiha Taki has always been curious about one thing. Kyuubi is said to be able to share perception with its host. So... when Senju Hashirama and Uzumaki Mito did that... would he feel it?

And judging from the plot, Kyuubi is also a man, so...

Well, no wonder Kyuubi is always so grumpy, it's understandable.

.........

"Coming?" After entering the living room, Uchiha Taki saw Uzumaki Mito.

An old man who looks very kind.

Even though she is not young, she still looks energetic, and there are diamond-shaped lines of Yin seal on her forehead, but her old face shows that she has not mastered the art of creation and regeneration.

"The art of creating regeneration should be Tsunade's original creation...it can promote cell division or inhibit cell division. It can not only effectively maintain the body's youthfulness, but also significantly increase its life span." Uchiha Taki wants to learn this ninjutsu, after all, it is People from the Rabbit country have a strong pursuit of "immortality".

"You seem to be distracted?" Looking at the distracted Uchiha Taki, Uzumaki Mito asked with a smile. Her kind face made her look quite kind, "What are you thinking about?"

"It's just a new ninjutsu." Uchiha Taki did not explain in detail. It is unclear whether Tsunade will create regeneration at this point in time, so it is better not to talk nonsense.

"That's so rude, Taki!" Senju Tobiran scolded with a frown, "Don't think about these things when facing your elders."

"Okay, don't be so serious. There is no topic. You can talk about the ninjutsu you thought of. Maybe I can help." Uzumaki Mito smoothed things over. The oldest and senior person present She deserves to do these things.

"Okay." Uchiha Taki nodded, and after thinking about it for a while, he spoke about his idea.

"In previous research, I discovered that chakra can be controlled according to one's will, and by studying the physiology of cells, I discovered the processes required for cell division and listed them down." Uchiha Taki said one by one. "Furthermore, human lifespan is actually determined by cells. There is an upper limit to the number of divisions of each cell in the body. Cells with stronger vitality have a higher upper limit, but they are also easier to divide, so each person's cells divide The time difference between the arrival of the upper limit of the number of times will not be too big, so the actual life span of each person is not very different."

"So? What are you going to do?" Senju Tobirama asked, thinking this might be an interesting ninjutsu.

"I think that chakra can be used to induce cell division or inhibit cell division. As long as this process is designated as a ninjutsu and used, then in daily life we ​​can divide our own cells as little as possible, which can significantly extend our lifespan. , Wounds can quickly divide cells during combat, thus achieving rapid healing." Uchiha Taki said about the effect he wanted.

"And after reaching this step, we can further develop. Every cell in the human body actually contains the information of all human cells, but the final expression is different. If we can control each cell through chakra, it will divide. The end point of success, then... the disability may be eradicated." Rejection also exists in the Naruto world, but... it is relatively less serious, and no matter how severe the rejection is, it cannot offset the effect of chakra.

"You mean to find cells that can continue to divide and then have them divide into specific organ cells and finalize them, and then install them on patients who are missing organs?" Senju Tobirama raised an eyebrow. He felt that this was not possible. It doesn't work, although it's a bit outrageous, but there are no limits to ninjutsu, maybe it can really be done.

"No, it doesn't need to be so troublesome at all. We can reverse the process of cell differentiation, convert them into primitive cells, and then directly guide the primitive cells to divide and generate the organs we need." Originally, Blue Star's technology was not up to the mark. We have reached this point, but this world has unscientific energy like chakra, which makes this kind of thing possible.

"There is another problem. The operations at the cellular level are too delicate. If you want to experiment, you must select ninjas with sufficient qualifications, but such ninjas are precious resources..."

"I'll do it!" Before Senju Tobirama could finish speaking, Uchiha Taki answered directly.

"The consequences of the experiment cannot be determined. If a large number of cells are induced to revert to the original cells, you may die." Senju Tobirama knew about the existence of embryonic cells and stem cells. His research had reached this level long ago, otherwise he would have died. It is impossible to create a "reincarnation of dirty soil" that performs magic based on blood and other cell tissues.

"Don't worry about this. My chakra control ability is extremely strong. Recently, I have also noticed that I can accurately gather my chakra into a certain cell for operation, and even to a more precise level for use in experiments. It's enough." Uchiha Taki was not worried about his own safety at all. He could just experiment on his fingers. If something went wrong, he would throw away his hands.

Just install one later.

"Drink tea." Uzumaki Mito, who couldn't say anything next to him, silently made tea and brought it over.

"Thank you." Uchiha Taki took it very naturally and thanked him, then continued the discussion between the two.

"And as long as a certain ninja can learn the ninjutsu I envisioned, then the ninja's control ability has at least reached the cellular level, and he can even control his own cells to achieve things that were impossible before." Uchiha Taki said, " For example, delaying one’s own aging or something.”

"Really!" Uzumaki Mito asked, grabbing Uchiha Taki's shoulders.

Only then did Uchiha Taki realize that her hands were so strong!

Even the body that had been strengthened for a long time felt severe pain under Uzumaki Mito's subconscious exertion.

"Yes, this level should not be a problem." Uchiha Taki said, "Human aging is nothing more than the loss of function of cells in organs and the aging of surface cells. After learning this technique, you can replace your own aging cells with new ones. Cells, as long as they have enough chakra, aging is almost non-existent."

Even the concept of old age and death may disappear.

"The experiment can be carried out. If you have any needs, you can ask me." Uzumaki Mito made the decision on behalf of Senju Tobirama. Ninjutsu that can make you younger is every girl's dream, even she who is already old is no exception.

"Sister..." Senju Tobirama felt helpless, "We still have to finalize some details. These things cannot be figured out with just a concept."

"Oh, tell me then." Uzumaki Mito waved his hands in a "all ears" posture.

Seeing this, the two could only continue to discuss.

"The seals that can accurately control chakra include the "final seal" and "you seal". When creating ninjutsu, you can add these two seals to ensure the success of the ninjutsu." Senju Tobirama said skillfully, regardless of the initial There are as many seals as you want, as long as the ninjutsu can create them, and you can slowly reduce the number of seals in the future.

"Yes, and my idea is to make this ninjutsu a "permanent ninjutsu". After all, it needs to exist in normal times, so the necessary point is the issue of duration and consumption. I think the duration can be like this..."

Uzumaki Mito looked at the scene where two people, one large and one small, were discussing ninjutsu, and in a trance, he seemed to see the two Senju brothers sitting together and chatting together before.

"That's great..." Uzumaki Mito said with a smile.

"Stupid!" Such a voice rang in her ears.

"What, are you jealous?" Uzumaki Mito asked in his mind.

"Are you kidding me? Will I be jealous of you cricket humans?"

"Hehehe...you have to pray for them to succeed, otherwise...you will have to change places in a few years." Uzumaki Mito said easily.

"Let me out! I've had enough of this old man in your body!"

"That's not possible. That guy Hashirama did something wrong, but we can't bear the consequences. We can only make you suffer." Uzumaki Mito said helplessly. She never thought that Senju Hashirama would do anything to him. The beasts were separated, and judging from the results, it was undoubtedly a huge mess.

"Damn!" Kyuubi gradually became irritable.

Calm down, anger can't change the facts, you might as well think about how to live a more comfortable life. "Uzumaki Mito said that she is not a good person. Even if her choice will hurt Kyuubi, she will never let Kyuubi leave.

After all... once the Kyuubi leaves, even if there is no revenge on Konoha, several other villages that have received the news will definitely use the tailed beasts to threaten Konoha, which may cause huge losses to Konoha.

This is what she doesn't want to see.

"I've wronged you, Kyuubi." Uzumaki Mito apologized in his heart, but his mind remained firm.
