"The world is made up of matter and spirit, and the spiritual aspect is not mentioned for the time being, let's talk about matter. Matter is made up of tiny particles such as molecules, atoms, electrons, protons, quarks, etc., which are polymerized into macroscopic matter by high-speed movement under the action of force. I think you know a lot about Orochimaru?" Rope tree asked, looking at Orochimaru with a serious face.

"Of course. But this is physics, and we're supposed to be talking about biology?" Orochimaru doesn't understand how these basics have to do with immortality?

"Living things are also made of matter, aren't they?" Rope Tree asked rhetorically and motioned to Orochimaru to calm down, "Since all particles are constantly changing and moving, causing the state of all matter to be unstable, no matter is eternal. ”

"Rope tree-kun, you are right, if the organic matter that makes up the human body loses its activity, it will soon decay, but the active body can only hold life through metabolism, we don't need all the substances that make up the whole body to exist forever, we just need to ensure that the body has enough vitality to maintain the metabolism and regeneration of cells to obtain eternal life!" Orochimaru felt that the rope tree might be confusing the concept.

"Unfortunately, it's almost impossible! Because of the oxidation reaction, the cells in the human body also have a limited lifespan! Once the number of cell divisions reaches the upper limit, the human body will naturally decay and die! Rope shook his head and vetoed Orochimaru's idea.

"That's why I'm interested in Joki-kun's body! Wood Escape Blood Inheritance can create life! As long as the vitality is sufficient, the cells can be freed from the limitation of lifespan and thus immortal! Orochimaru said feverishly.

"It's a pity that Mu Dun can't do this!" Rope Tree shook his head again and said, "My grandfather has developed Mu Dun's power to the extreme, and his vitality still can't completely stop the aging of cells!" It's just a matter of slowing down the process. ”

"Maybe it's because of a lack of vitality? If there is enough vitality......" Orochimaru guessed still immortally.

Rope tree directly interrupted Orochimaru's words: "No, Orochimaru! I won't hide it from you, in fact, the reason why Mu Dun was able to create life was because Mu Dun Chakra added the Yang Dun attribute! And Yang Dun Chakra is a manifestation of the vitality in your and my mouths! You want to increase your vitality with Yang Dun Chakra...... What's the difference between that and eating your own flesh to stay alive?"

"What if it's a foreign chakra? Like tailed beasts?" Orochimaru is still unwilling and wants to make up for it by other means.

It's a pity that the rope tree still shook his head and said, "Even if you absorb someone else's chakra, you can't live forever!" The problem of the longevity of cells cannot be solved by the amount of life force at all! Not to mention my grandfather's almost endless amount of chakra, even with my current amount of chakra, I can easily meet the upper limit of the absorption of chakra by some cells in my body! When the life force in the cell is saturated, it does not stop dividing and aging, but only prolongs the lifespan! I think you also have a yang chakra in your body, right? A little experimentation is all it takes to draw conclusions! Moreover, with the quality of ordinary people's yang attribute chakra, it can't even delay cell aging! Therefore, only my Thousand Hands and Uzumaki Clan can prolong their lives, but due to the quality of the chakra, this extension also has a limit. It is precisely because the quality of my grandfather and my Yang Attribute Chakra far exceeds that of other clansmen, that Mu Dun can exert the greatest power in our hands!

So I speculate that when the mass of the yang attribute chakra reaches the limit of perfection, it will be possible to completely solve the problem of the longevity of the cell. ”

"Then find a way to improve ......" Orochimaru stopped and kept silent as soon as he said it, if the quality of chakra was so easy to improve, the ninjas in the ninja world would have already succeeded, so why should it be his turn to experiment? He had just said something stupid driven by obsession.

"You've thought of it too, haven't you? Orochimaru! Now in the entire ninja world, among the known chakras, the highest quality is the immortal chakra, and the legendary six immortals can also resist the erosion of time, and in the end they can only accept the fate of death. Even if we reach the height of the Six Realms Immortals, we won't be able to live forever! And want to surpass the Six Dao Immortals...... IMHO, this is not something that can be achieved by scientific experiments, and it may be even more difficult than immortality! ”

Hearing Rope Tree's final conclusion, Orochimaru nodded, although he was a crazy researcher, but he was not a fool who couldn't accept reality, and he quickly realized his mistake under the conclusion supported by experimental evidence: "Rope Tree-kun is right! It is almost impossible to have eternal life physically! So we can only start with the soul?"

"I'm glad you changed your mind so quickly! That's what a researcher should be! Rope Tree was happy that he was able to convince Orochimaru, and couldn't help but open his mouth in admiration.

"Hehehe...... I still have this amount of equipment, and I'm not an old stubborn person who clings to old ideas! Orochimaru was also happy with Naruki's compliment, which was completely different from the others from the same kind of appreciation, "It seems that Naruki-kun also thinks that he should start from the soul side?"

"Yes, I think only the soul and the spirit can reach eternity in the true sense. Even the vitality comes from the soul! Rope Tree spoke his theory.

"Oh? Very novel point of view. I agree that the soul can exist forever and continue to carry out the cycle of life and death, but why is it said that the vitality comes from the soul? Is there any evidence?" Orochimaru asked curiously.

"All life has a soul! Even plants are spiritual! If a dead thing is spiritual, it can be counted as life in a sense! The difference is only in the strength of the spirit! Of course, human beings are the most spiritual, followed by animals, then plants, and even bacteria have spirituality, but they are too small to be negligible. So speculate that the life force comes from the soul! Nothing without spirit is nothing but dead without life! ”

"Bang Bang!" After listening to the rope tree's reasoning process, Orochimaru unconsciously applauded: "It's really an unheard of theory and there are no flaws in logic!" In other words, if the spirit is stronger, the soul will be stronger, and even the vitality will be strengthened? Is this a theory developed by Rope Shu-kun himself?"

"Having said that, this is just a logical expansion and speculation based on the Buddhist theory to come to a conclusion." Rope tree humbly told the truth.
