It's not quite right to say it's a variation. Although the whirlpool family has a large amount of chakra due to physical reasons, it also has a good suppressing effect on the tailed beast chakra, and coupled with the strong vitality of body cells, the hair is basically bright red, and the individual is only in color. There is a slight difference in shade, but a complete change in hair color is quite rare.

"Not only hair color, have many other traits undergo unknown changes?"

After removing the commonalities, some physical characteristics are really suspicious.

Blonde hair and blue eyes are all characteristics of Minato Namikaze, and there are other differences, such as adaptability to natural energy and chakra, Uzumaki Naruto is far better than Incense.

"Basically, all the characteristics that may be affected by Chakra are all the genes of the water gate in the dominant state!"

Generally speaking, DNA and proteins in human cells combine to form chromosome sets, which control the characteristics of all aspects of the human body.

But the reality is not completely absolute, and there are some strange exceptions in the human body.

For example, the circulating DNA in the blood, the DNA in the episomal state for some reason, and even the mitochondria that exist in each cell have their own independent genetic material and genetic system. Although limited by the size of the genome, they are only a semi-autonomous organelle, but they can affect cell differentiation, cell genetic information transmission, and even regulate cell growth and cell cycle.

From the above, it can be seen that there are many types of genetic material that can affect the human body.

The clone waited for the main body to read the report for a while before saying: "We don't have to worry about too professional issues, but only need to know that it is feasible to affect a person's genetic material traits. There is no extraordinary power in the previous life, and we can only rely on pure science. We use technology to verify carefully. The effect of the means of affecting DNA is minimal. Cancer has not yet been conquered. It is impossible for us to study these profound professional issues thoroughly. This is the systematic engineering of the whole biology. It's basically impossible to get any results from research in a short period of time..."

"However, we don't have to be so troublesome. The root cause of the problem is actually very obvious. The key lies in Chakra..."

Inspired by the spell seal Chakra, Sasuke Uchiha not only changed his skin color and hair color, but even grew wings. In contrast, Naruto Uzumaki's hair color change is really just a small problem.

"Although there is no reliable conclusion yet, we have a guess that Miaomushan spared no effort to spread the toad immortality, and the reason for the creation of the Chongwu family in Longdidong is the same. They changed the fate of some people. There must be a return..."

"It can be speculated from the current situation that the immortals of the two holy places did not want to harm these people. This should just be a process of mutual benefit."

After waiting for the main body of Mizuki to read the experimental conclusion in his hand, the clone continued,

"The key to the matter is likely to return to Chakra and natural energy. Also, be careful when you use the immortal mode yourself, and pay attention to the clues at the same time!"

Shuimu's clone paused, then said hesitantly, "It is impossible to judge the severity of the problem for the time being. However, when we were doing experiments and exchanges, we had an opinion, and I hope you will pay attention to the main body. These non-human intelligent creatures have an opinion. The origin is not simple, as for the final and credible research conclusion, it must be supplemented by social observation to reach the conclusion..."

"Oh? Is it so serious, involving all mankind? Could they be bad for mankind?"

"No, although it can't be proved, it is extremely unlikely that they will directly threaten human beings. The question is, have you ever thought about it, in a world with multiple intelligent creatures, there is also such a magical thing as natural energy, what is human beings? Can you become the ruler of the ninja world?"

"Do you remember the evolutionary history of humans in the past life? Humans went from Africa to the world. During this period, they were on the verge of extinction countless times. Even if they spread all over the world later, humans almost lost in the competition with their close relatives. If it weren't for climate change, It may be Neanderthals, not us, that will replace modern humans."

"The competition for survival is so cruel and human beings who do not have the upper hand can actually become the spirit of all things in the hands of such a terrifying creature. How likely is it? If there is only one competitor, that's fine. How many species are known? , Ninja cats, mongooses, giant toads who know magic, big snakes who know magic, the largest creature in theory - the slug fairy of Shibone Forest, and some intelligent species that we don't know..."

After thinking about it, Shuimu said: "These immortals in the holy land of psychic beasts seem to have no intention of competing with humans for the dominance of the ninja world. Instead, they are doing their best to help humans. Those psychic contracts with some traps, It's not unacceptable to humans, it's just..."

"Does it feel weird?"

The body of Shuimu pondered for a long time, but still had to nod: "Humanity is in a fierce competition, and the five major countries fight every ten years. But I didn't expect that these aliens are so enthusiastic about human beings, and the spirit of internationalism is not enough. Describe their noble feelings!"

"Love and justice can solve many things, but the competition for living space is not so harmonious. Therefore, there must be problems that we have not considered, and this is likely to affect our position in the final battle!"

Shuimu's body smiled: "The righteous and awe-inspiring villain's rhetoric really makes excuses!"

The clone ignored the ridicule of the main body, and instead said blankly: "In fact, apart from our own mental defects, we are already very powerful. We have a sharp sword in our hand, but we don't know where to point it!"

Jiraiya's point of view of fighting for the dominance of chakra is correct, but it is only a means, not a reason.

...

When Mizuki came to the Chunin exam venue again, it didn't take long. However, the battle between Hyuga Neji and Omoi below is drawing to a close.

"Mr. Shuimu, you are finally here."

After the treatment, Inuzuka came to the stands to watch the next game. After finding that Mizuki was late, he complained a little dissatisfiedly, and Hinata Hinata, who was on the side, was a little embarrassed and hesitated.

"It's fine, try harder next time!"

Mizuki turned his head to observe, and the clone was no longer here. Hatake Kakashi and Matekai watched the game not far away, while embankmented the suspicious characters in the audience...
