There is no doubt that White Zetsu, a creature with almost no upper limit to its lifespan, is a huge loophole in this world. However, considering the way White Zetsu was born and its origin, it is not difficult to understand that it is a by-product of the power of Kaguya Otsutsuki. In this magical world, it is not surprising that some immortal monsters appear.

Since it fell into Mizuki's hands, Mizuki has spent countless energy and resources to study the cell characteristics of White Zetsu. After sufficient demonstration, Mizuki was surprised to find that the DNA chain after the division of White Zetsu cells showed no signs of telomere wear. In other words, White Zetsu can really achieve immortality biologically.

From Mizuki's knowledge, the structure of the human DNA chain shows that this should be impossible. If the genetic material of White Zetsu cells is not chain-like but circular like a few bacteria, with no beginning or end, and a DNA structure that can theoretically be perfectly replicated, then it is possible.

The conclusion is obvious. It is caused by other reasons inside the cells, or it may be the characteristic of the ninja world - chakra that causes the immortality of White Zetsu.

Shuimu was pressed for time and it was impossible for him to do more exploration. Moreover, this was something beyond his knowledge, and he had to conduct independent research and establish a new theory. Sorry, Shuimu didn't think he could do it.

However, not understanding it does not mean it cannot be used. So Shuimu put a bold idea into practice, which is the current experimental result.

The method was not difficult. The genetic material of Mizuki was used to replace the genetic material of the white Zetsu cells. The experiment went unexpectedly smoothly and the results were very satisfactory.

Does the ninja world have this level of cloning technology? Mizuki did some research and found nothing. Even Orochimaru still uses cell transplantation as the mainstream method, which shows that the biotechnology of the ninja world has not yet developed to this level. The most advanced cloning technology is still at the level of activating the universal cells in the body of an organism by chance, and then dividing the embryo after proper development. It is far from the level of Mizuki's all-purpose potion that can be reborn by a drop of blood, and naturally there is no such direct manipulation of genetic material.

This composite cell is similar to the cloned Dolly the sheep in the previous life, except that it is not a simple self-clone. After using the omnipotent potion to stimulate the splitting characteristics, and then with the guidance of its own chakra, a special clone that is exactly the same as Shuimu is generated. Shuimu does not know what the substance is that makes this miracle happen, but the conditions for achieving it can be met.

Then the somatic cells of this special clone are injected into other ordinary clones. After several generations of evolution, safe sample cells with stable shapes are born. After being injected into the main body, these cells that perfectly adapt to their own bodies begin to slowly replace the original aging cells. The identical genetic DNA fundamentally eliminates rejection reactions. Simply put, it is to use the DNA information backed up earlier to make a super cell and slowly change yourself into a new body. This subtle change will not have too much impact on your spirit.

Sure enough, the result was exactly as Shuimu expected. The genetic material in the White Zetsu cells was actually irrelevant. What was important was other unknown things. At the same time, the White Zetsu's amazing ability to possess, his ever-changing clones, and his superb simulation ability were well explained, especially the Wood Release - the change of objects, the perfect simulation after absorbing other people's chakra, which was a change at the genetic material level. It fully demonstrated that there were special substances in the White Zetsu cells that were sensitive to chakra and could change the cells fundamentally. So it was not strange for Shuimu to replace the White Zetsu DNA with his own, occupy the magpie's nest, and then use chakra to warm it. All he needed was the necessary knowledge and imagination.

"Does this count as achieving physical immortality? Even Orochimaru couldn't do it, but I did it so easily?"

Shuimu, who is always worried about gains and losses, always has a feeling of unreality.

"As expected, this world is going to be messed up. Life and death are just like a joke."

Mizuki, who was a little dizzy, certainly did not forget that the foundation of all this was created by the White Zetsu cells that played with the world like a child. Many people have received his favor, including Uchiha Madara, Uchiha Obito, Shimura Danzo, Orochimaru, and now it is Mizuki's turn.

Once the imminent shadow of death is dispelled, there will be enough time to study the deeper issues of White Zetsu cells. The victims in the Infinite Tsukuyomi and the first generation cells are all things that changed the landscape of the ninja world.

However, there is another problem that is about to be dealt with, that is Moonlight Gale, but unfortunately, Shuimu can no longer find his normal cells before aging, so he can only prevent it from getting worse.

To put it bluntly, the method invented by Shuimu is not to restore youth, but to stop aging. It is basically useless for a dying person.

"Let's do our best and leave the rest to fate. If we can save his life, retiring and becoming an ordinary person might be a good thing!"

…

A few days later in the Hokage's office, Tsunade frowned as she looked at the treatment plan handed over by Mizuki.

"How can you make me believe such an unclear method? This is a human life. I cannot let it be your experimental subject!"

"Isn't there anything we can do about this?" Shuimu asked, "Do you have a better treatment method?"

It has been four or five months since Gekko Gale was seriously injured and could not afford it. It was a scorching summer back then, and now it is almost winter. Being able to hold on for so long is already the pinnacle of Tsunade's medical ninjutsu, but this is not a solution. Gekko Gale's internal organs have been showing signs of failure from time to time, and the condition can no longer be alleviated. There is really no hope for him.

Tsunade was silent for a long time, and finally had to say: "I will discuss it with his family and let them make the decision. In this case, you should get ready, and once there is news, execute it as soon as possible."

Moonlight Gale's condition has almost reached the point where he has to try everything possible.

Mizuki received the order and walked out of the Hokage's office building, wandering on the bustling street with a relieved smile.

"I've passed the first set of levels. Is the next stage a more troublesome spiritual war?"

Although he didn't know if there would be any problems in the end with such an opportunistic method, at least for now, Shuimu had tested all aspects he could think of and found no signs that there was anything wrong with his body.
