It is not quite appropriate to call it a mutation. Although the Uzumaki family has a very large amount of chakra due to their physical constitution, which can effectively suppress the chakra of the tailed beasts, coupled with the strong vitality of their body cells, their hair is basically bright red, and there are only slight differences in the depth of the color between individuals, but it is quite rare for the hair color to change completely.

"Not only the hair color, but many other traits have undergone unknown changes?"

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

Golden hair and blue eyes are the characteristics of Minato Namikaze. There are also some other differences, such as Uzumaki Naruto's adaptability to natural energy and fairy chakra is much better than Karin.

"Basically, all the characteristics that may be affected by chakra are in the dominant state of Minato Namikaze's genes!"

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

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

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

From the above, we can see that there are many types of genetic material that can affect the human body.

The clone waited for the original body to read the report for a while before saying, "We don't need to get hung up on too professional issues. We just need to know that it is feasible to influence a person's genetic material traits. In the previous life, there was no extraordinary power, so we could only rely on pure science and technology to carefully verify. The effect of influencing DNA is minimal, and the fact that cancer has not yet been conquered is proof of this. It is impossible for us to thoroughly study these profound professional issues. This is a systematic project of the entire biology. With two hundred years of scientific accumulation in the previous life, it is basically impossible for us to produce any results in a short period of time..."

"But we don't have to go through so much trouble. The root of the problem is actually very obvious. The key lies in chakra..."

The activation of the cursed chakra not only changed Uchiha Sasuke's skin color and hair color, but also made him grow wings. In comparison, Uzumaki Naruto's hair color change is really just a small problem.

"Although there is no reliable conclusion yet, we have a guess that the reason why Myoboku Mountain spared no effort to spread the Toad Magic is the same as the reason why Ryuchi Cave created the Jūgo family. They changed the fate of some people, and if they paid something, they must get something in return..."

"Based on the current situation, the immortals from the two holy places do not intend to harm these people. This should just be a mutually beneficial process."

After Mizuki's real body finished reading the experimental conclusion in his hand, the clone continued speaking.

"The key to this matter is probably still going to come back to chakra and natural energy. Also, be careful when you use Sage Mode yourself, and keep an eye out for clues!"

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 discussing the experiment earlier, we had an opinion that I hope you can pay attention to. The origins of these non-human intelligent creatures are not simple. As for the final credible research conclusions, they still need to be supplemented by social observations to draw conclusions..."

"Oh? Is it so serious that it involves all of humanity? Will they harm humanity?"

"No, although it cannot be proven, the possibility that they directly threaten humans is extremely small. The question is, have you ever thought about it, in a world with many intelligent creatures, and at the same time there is such a magical thing as natural energy, how can humans become the rulers of the ninja world?"

"Do you remember the history of human evolution in the past? Humans spread from Africa to the rest of the world, and were on the verge of extinction countless times. Even after they spread all over the world, humans almost lost in the competition with their close relatives. If it weren't for climate change, modern humans might have been replaced by Neanderthals instead of us."

"The competition for survival is so cruel. Humans, who are not at an advantage, have become the most powerful creatures in the hands of such terrifying creatures. How likely is this? It would be fine if there was only one competitor, but how many species are known? Ninja dogs, ninja cats, mongooses, giant toads that can perform magic, giant snakes that can perform magic, the largest creature in theory - the slug fairy of the Wet Bone Forest, and some intelligent species that we don't know about..."

Mizuki thought for a moment and said, "It seems that the immortals in the sacred land of summoning beasts have no intention of competing with humans for the domination of the ninja world for the time being. Instead, they are doing their best to help humans. Those summoning contracts with some traps are not unacceptable to humans, but..."

"Does it feel weird?"

Shuimu pondered for a long time, but still had to nod his head: "Humans are fighting among themselves, and the five major countries fight a war every ten years or so. But I didn't expect these aliens to be so enthusiastic about humans. The spirit of internationalism is not enough to describe their noble sentiments!"

"Love and justice can solve many problems, but the struggle for living space doesn't make sense to be so harmonious. Therefore, there must be problems that we haven't considered, and this may affect our position in the final battle!"

Mizuki's original body smiled and said, "The villain who seems to be so righteous is really good at making excuses!"

The clone ignored the original's teasing and said in a daze: "In fact, now, except for our own spiritual defects, we are already very powerful. We have a sharp sword in our hands, but we don't know where to point it!"

Jiraiya's idea of ​​fighting for control over chakra was correct, but that was only a means and not a reason.

…

When Mizuki came to the Chunin Exam venue again, not much time had passed. However, the battle between Hyuga Neji and Omoi was almost over.

"Teacher Mizuki, you are finally here."

After receiving treatment, Kiba Inuzuka went to the stands to watch the next game. After noticing that Mizuki was late, he complained a little dissatisfied, and Hinata Hyuga beside him was a little embarrassed and hesitated to speak.

"It's good that you're alright. Try harder next time!"

Mizuki turned around and observed that the clone was no longer there. Hatake Kakashi and Might Guy were watching the game not far away, while keeping an eye out for suspicious people in the audience...
