Naruto started cultivating immortality from creating the Six-fold Immortal Thief

"Two theories, Yusuke, you are really amazing!"

Orochimaru looked at Yusuke with surprise, and was even more amazed at Yusuke's endless ideas. He never thought that a person's thinking could be so wild and unrestrained, and not restricted by the human world at all.

Yusuke smiled and did not hide it, because he knew that it was not enough for one person to create a true practice method. Dharma, wealth, companions and land must all be available to create a true practice method.

"The first theory is what I am practicing now. Through the immortal chakra, I can create the perfect eight systems of the human body just like I perfected the six-storey immortal thief, so that life can complete its evolution and completely become an immortal body that belongs to me.~！"

Orochimaru, who knew the human body very well, heard this theory and murmured in disbelief:"If the eight human systems, including breathing, digestion, circulation, and endocrine, are all built to perfection, I can't imagine what people will look like then?!" With indestructible defense, thunder-like bursts, a gluttonous appetite, lightning-fast reactions, and a body that is immune to all poisons, immortality will no longer be a dream.

Thinking of this, Orochimaru smiled triumphantly. He felt that he was getting closer and closer to immortality. As long as he followed this theory, his dream would definitely come true.

After laughing triumphantly for a while, Orochimaru realized that he had lost his composure. He coughed twice and said seriously,"Yusuke, what about the other theory?!" Yusuke smiled and continued,"The second theory is just a theory. I haven't tried it, but according to my speculation, it is likely to be realized. And as long as it is realized, immortality is just the most basic!"

Hearing this, Orochimaru was even more shocked. He originally thought that the first theory that could make people immortal was shocking enough, but he didn't expect that the second theory of immortality was just the most basic. He quickly asked,"What is the theory?!"

"Actually, this theory is the result of my research on the Tailed Beast Chakra. I found that Chakra can not only be transformed into matter, but also from matter into Chakra."

"So what?!"

Orochimaru was a little confused. He knew that Yusuke had a large amount of Nine-Tails Chakra in his hands, and he also obtained Shukaku's tail in the battlefield of Wind Country last time, but is there anything special about these chakras?!

He has also studied the tailed beast chakra. Although he thinks this kind of chakra is very special, it doesn't help much for his research, so in the end it was left unfinished. He doesn't understand how the tailed beast chakra can help humans. Yusuke's eyes were full of pride, and he smiled:"Teacher, you must know that the tailed beasts are immortal creatures that can be seen in the ninja world. Their history can be traced back thousands of years ago."

"I understand what you said, but the tailed beasts are chakra creatures, they don't have a physical body, isn't it normal for them to live forever?!"

After being reminded, Orochimaru reacted immediately, and he vaguely guessed Yusuke's idea in his heart, and at the same time he was even more confused. He had studied the tailed beasts, so he naturally understood the life form of the tailed beasts, but what did this have to do with Yusuke's theory?

""Teacher! Didn't I just say that?! Chakra can be transformed into matter, and matter can also be transformed into chakra!"

As he spoke, Yusuke picked up a stone with his foot and put it in his hand. The senjutsu chakra condensed on the stone. Under Orochimaru's shocked eyes, the stone was quickly assimilated into chakra under the infection of the senjutsu chakra, and in the blink of an eye it turned into stone again, and then it continued to transform between stone and chakra.

"According to this discovery, I found that matter and energy are not independent of each other, but can be transformed into each other. In this case, just as the human body can be transformed into chakra life through chakra, does it mean that people can also be immortal like the tailed beasts!"

The tailed beasts are not simple chakra lives, they can be transformed between matter and energy, just like in the original work, Kinkaku and Ginkaku swallowed the meat of the Nine-Tails in its stomach and obtained the Nine-Tails' chakra.

And the tailed beast transformation is to first transform the human pillar into chakra, and then condense the matter into a tailed beast. It was with this conjecture that Yusuke wondered if he could create a chakra version of the reverse life triple.

After listening to the complete theory, Orochimaru also began to reason in his mind and found that the possibility of this set of theories was much higher than the previous human body system theory. The most important thing is that the Dragon Immortal Mode he studied has already had a trace of material transformation into immortal chakra. He suspected that Yusuke proposed this theory for him.

Orochimaru really guessed right about this. Yusuke had obtained the Nine-Tails' chakra a long time ago and had never stopped studying it. In this process, he also unintentionally He discovered the mutual conversion property between chakra and matter.

After discovering this property, the practice method of the three levels of reverse life came to his mind. He was not opposed to transforming life into the life form of the tailed beast, because in his speculation, the final form of life evolution is a special life that can transform between energy and matter.

But because of the Otsutsuki clan, Yusuke always felt that it was inappropriate to transform into a life state similar to the tailed beast now, and the strength of the nine tailed beasts has not increased much in so many years. He was also afraid that his strength would not increase if he transformed into this life form in advance.

The most important thing is, will the food eaten by the transformed tailed beast still taste good?! If the food eaten by the transformed tailed beast has no taste, it would be better to kill him.

So he wanted his teacher Orochimaru to help him try it, and by the way, perfect this set of theories, lay a foundation for his future practice, and let Orochimaru���After all, as long as Orochimaru can be immortal and learn all the ninjutsu, he doesn't care about gender, life form, etc. How can he let go of such a useful tool?

……

Feeling Orochimaru's gaze, Yusuke smiled and said,"Teacher, do you want to try the second theory?!"

Orochimaru was a little strange:"Yusuke, tell me honestly, is this theory specially designed for me?!"

Yusuke waved his hands again and again:"Teacher, don't get me wrong! I discovered this theory accidentally, but it is not suitable for me now. At the same time, I found that your Sage Mode is very consistent with this theory, so I want to give it to you!"

"Isn't it suitable now?!" Orochimaru accurately grasped the key point, looked at Yusuke and nodded:"In this case, let me perfect this theory!"
