A long time ago, Mizuki had considered the issue of the lineage of this world.

Humans are the dominant intelligent race in the ninja world, and it stands to reason that there shouldn't be too many mixed races with other races.

Even if there are many people in the ninja world, there is a very small possibility of large-scale hybridization, and it is more likely that a few special bloodlines will gradually disappear in the dilution from generation to generation.

The ninja world is not a very large world, and theoretically human beings should form a race with the appearance and quality of the vast majority of individuals.

But strangely, Mizuki didn't find such signs.

Even if you are tall, short, fat and thin, you don't feel that it is an eyesore to see too much of your colorful hair and pupils, but what is the problem of having a shark face? There are also those with many hands and feet, horns on their heads, bodies like rubber and noodles, and water and air......

Some of these are called blood inheritance limits.

The bloodlines of alien races like Otsumu have gradually integrated into the human race, and as long as there is no awakening of the blood inheritance limit or atavism, it will basically not show anything different from ordinary people.

Why is it that human beings' own differences are so difficult to eliminate, or even show no signs of erasing differences?

It wasn't until Mizuki figured out the impact of the psychic contract provided by Myoki Mountain on Bo Feng Mizumon and Naruto Uzumaki that Mizuki finally found a clue.

Chakra is the culprit behind such a diversity of human genetic traits in the ninja world.

After all, there are only a few people like Orochimaru and Mizuki who use biotechnology to actively adjust, and they can't affect the human race as a whole, but the ubiquitous Chakra can do this.

For example, Haruno Sakura, who practiced the control of the tailed beast chakra and then learned to master the immortal mode, the dominant characteristics that its descendants may inherit have undergone a great change.

As for the mutations caused by other reasons, there are even more, and the superficial changes in hair color, eye color, and skin color are not worth mentioning, but the blood inheritance limit formed by the fusion of chakra's nature changes is not a trivial matter.

Melting, Ice, Boiling, etc., these genetic traits accumulate from generation to generation, and they will form a stable blood inheritance limit or secret art family.

"Chakra, imperceptibly accelerating the planning process of mankind! The one who is at the forefront of mankind and leading the way is the ninja!"

It is no wonder that the level of productivity in this world is not very advanced, but the survival rate of newborns is very high, because the physical fitness of the human beings in the ninja world greatly exceeds Mizuki's expectations.

There is also some side evidence that large-scale plagues are rarely prevalent in the ninja world, and there are not many types of fatal diseases for ordinary people.

However, extremely talented blood ninjas like Uchiha Itachi and Kaguya-kunmaro have a higher probability of developing incurable congenital diseases.

Chakra is not radioactive radiation, and the probability of inducing undesirable mutations is extremely low, as long as ordinary people do not have accidents, the impact is very small, but the probability of ninjas who often use chakra to perform ninjutsu is much higher.

……

"It's all speculation and corroboration, so there's no substantive conclusion?"

Not long after returning to the village, Mizuki got the latest investigation report from the entity clone, Gongji,

"Your mission is social investigation, not the study of human genetic history, is it worth wasting too much energy on this report?"

Since each entity is given a great deal of autonomy, it is inevitable that the assigned tasks will be arranged differently.

Like not long ago, I fought with Payne Rokudo and still stood side by side, but they usually do their own things, and occasionally cooperate with each other.

Koji is the person in charge of investigating the structure and direction of the development of ninja society, focusing on the relationship between ninjas and commoners, and the reasons for the separation of the secular society represented by the ninja village and the daimyo.

Ever since discovering some unusual signs of the relationship between ninjas and civilians two years ago, Mizuki has been trying to find the cause, but it is disappointing that he did not expect to get such a result in more than two years.

"It's not surprising that you think so, but ......"

Gongzhi said seriously,

"These are not meaningless, the core of studying the social nature of the ninja world is to study ninjas. In the past two years of observation, I have always had a question about why the ninja world is the way it is now, where strength does not match power and power, status, and ninjas who master absolute force have actually lost their secular power. This is not the case with religious organizations, where the progress of civilization has led to the weakening of theocracy. There are gods in this world, but the status of ninjas with extraordinary powers is not high......"

"Huh?"

This entry point is kind of interesting,

"And what do you think?"

"I haven't figured out the final conclusion yet, but after finishing the report in your hand, I have some inspiration......"

"What is it?"

Mizuki asked with interest.

"We may have been misled by the memories of our past lives! The world in which supernatural forces exist cannot be applied to the social phenomenon that all men are created equal and need to be divided into classes by rules. ”

"System, power, law of the jungle?"

"It's not such a superficial thing. ”

Gongji shook his head,

"Power belongs to oneself, not to society and weapons. ”

Gongji's words made Mizuki stunned:

"You are denying the meaning of the existence of the ninja order, which is a cruel and reckless anti-social rhetoric than the law of the jungle. ”

"I'm not talking nonsense, think about it. How did Kaguya cleanse the world and then manage it, and what was the difference between Nagato collecting tailed beasts and using absolute force to establish a "kingdom of God" that ruled the world? Because Otsuki was an outsider? Or was Nagato more merciful? When did Uchiha Obito and Madara Uchiha take the will of ordinary ninja people to heart? Doing bad things with good intentions was just putting gold on their faces, and in the end, they were only for self-satisfaction. ”

"Think about yourself, you can't even trust the doppelganger, you never put the foundation of your power on others, but firmly grasp it in your own hands, if you don't have the current strength, what will the result be?"

"Because I'm strong and don't need to rely on anything external, I ......"

Mizuki thoughtfully,

"Even without Konoha Village, I'm still at the top of the ninja world. Power belongs to me, and all social institutions are only appendages that magnify the influence of power. ”

"You finally get it?"

"Superman and Spider-Man, who are self-disciplined and willing to obey the order of ordinary people, are idealized products, and Doctor Octopus will not care about them. ”

There is a plural number of unrestrained individual force, and the possibility of forming the current situation of the ninja world is too small, for more than a thousand years, except for the time when Otsuki Kaguya and the Six Dao Immortals were alive, most of the time, the ninja world was in war......
