The accident this time was very complicated, but the root cause was Mizuki's own negligence. He greatly underestimated the harm caused by the fake Jinchūriki derived from the Shadow Clone Technique. When the fake Jinchūriki clones with strong independence came up with inappropriate ideas, there were not many means of restraint. These clones, even if they have the same memory and way of thinking as the original body, will make different choices under different experiences and environments.

Belial did not directly answer the question about Shuimu's true self. Anyway, such a subjective topic would not yield any answer. He just looked at the nearly destroyed secret room, sighed and said, "I have also thought about the scene of meeting you, but I didn't expect it to be so soon. It's good this way. Sometimes I also worry about how far I will go!"

Mizuki's original body looked at Belial and said, "You and I both know that knowledge is power. From the beginning, I didn't intend to do anything to the clone. You should know whether I lied or not. But you also understand that the fake Jinchūriki clone, which came out of nothing, has inherited all my knowledge, but has no ties to this society, no worldly ties, and no moral shackles. Unrestrained desires will gradually lose their way in the continuous strengthening of self-will. You should know better than me the harm caused to the ninja world by a reckless me..."

"Of course, I've seen it clearly." Belial said with a wry smile: "The observation experiment progressed slowly. In the final analysis, it was because I was afraid. There were only four of us and it almost caused a big mess. You can create an unrestrained me, so I can also create a demon that destroys the world. Remember the term "invasion of alien species"? In the final analysis, we are invaders who came to the ninja world accidentally. If we act arbitrarily without any scruples, the damage we can cause will not be less than that of Kaguya Otsutsuki!"

There were so many fantasy works about the end of the world in the past, most of which were nonsense, but some of them made sense, especially in the ninja world with chakra, where the role of imagination was greatly enhanced, and some originally dangerous methods could be used. It might be difficult to play Resident Evil, but it was possible to study some super bacteria or dangerous synthetic organisms with some time. With Mizuki's knowledge, he might even be able to cleanse the ninja world.

"I'm almost sure it's clear!" Shuimu's main body concluded, "Communication is meaningful. Even if it's exchanging memories, we may not be able to accurately determine the cause of the difference. After all, we are a whole. It's just that the extended will is not shared, which leads to a deviation in understanding. I once thought that the deviation brought about by this environment would break through the limitations of working alone. However, harm also arises."

Mizuki tried to find an accurate description to describe the current situation: "Using the word 'fighting with both hands' is not quite accurate. I feel that the fake Jinchūriki clone that has left the field of vision is like an organ extending from the body. No, it is a tumor. It is benign, but it may worsen at any time."

"So, I will be treated as a lesion and removed?"

Shuimu's original body shook his head: "We are one body, so it is meaningless to talk about erasing. It is getting late, so let's exchange memories. This situation will change soon..."

"Oh? It seems like you've made a lot of progress recently." Belial was very interested in the new discovery of Shuimu's true self, "Let's put an end to the anxiety in our hearts as soon as possible..."

…

It took quite a while to clean up the broken laboratory, during which Mizuki also saw Kotsubaki's copycat Jinchuriki clone. The face was exactly the same, the way of speaking was exactly the same, and the difference from the original body was very small. Limited by the bias in chakra control talent, Kotsubaki's breath-retaining technique made little progress. The chakra used for the copycat Jinchuriki clone was not self-sufficient at all, so the original body needed to frequently replenish chakra and exchange memories at the same time. Although it was a bit troublesome, it also avoided the problem that happened to Mizuki.

Mizuki sealed up the clone who claimed to be Belial directly after exchanging memories with the original body and kept it for other uses. The remaining clone stayed at the base, which was very important. After handling all the matters, Mizuki left. Through this incident, Mizuki also deeply understood the practical significance of the saying that existence is reasonable. Most of the commonly circulated ninjutsu have been tested, and most of the sealed forbidden techniques definitely have immeasurable side effects and dangers. The Shadow Clone Technique is undoubtedly a semi-finished product. The superficial harm is the mental shock brought about by the return of multiple wills, but in the long run, the danger of this technique is really frightening, especially Mizuki's perfection to the point of physical clone, which gives the original body countless opportunities to try various behaviors that cannot be easily tried. After countless adventures, there will always be one time when it will go wrong.

When they returned to the village, it was not too late yet. After thinking for a while, Mizuki came to the training ground and stood quietly in the shadow of the trees, watching Kakashi Hatake doing combat training with Sasuke below.

Even though there are many shortcomings, Mizuki has to admit that Kakashi Hatake's strength and comprehensiveness are beyond Mizuki's reach, especially in physical skills. His excellent and balanced physique, under the stimulation of lightning chakra, has greatly improved his speed and flexibility. With his superb skills, especially with the help of the Sharingan, he is no worse than anyone else.

Mizuki himself was very envious of these gifted ninjas. You know, Mizuki's own body was actually not bad. His excellent body brought him a considerable amount of chakra, but his flexibility and reaction ability were far behind. The deviation in physical fitness made Mizuki not put too much effort into physical skills in his early development. Even now, he only relied on the great advantages of speed and strength in the Sage Mode to forcibly suppress his opponents. In fact, he did not play much advantage at all. However, Mizuki could still make the best use of his strengths and avoid his weaknesses in other aspects. But his disciple Sakura could not do it. Before the attainments of ninjutsu, illusion and sealing techniques were improved to the point where they could cover up the shortcomings, the huge loopholes in physical skills caused by the weak body could not be made up in the short term.
