A long time ago, Mizuki thought about the bloodline of this world.

Humans are the intelligent race that dominates the ninja world, and it stands to reason that there should not be too many hybrids with other races.

Even if there are many human and alien intelligence species in the ninja world, the possibility of large-scale mixed blood is extremely small, and it is more likely that a few specific bloodlines will gradually disappear in the dilution from generation to generation.

The ninja world is not a big world. In theory, human beings should form a group with little difference in appearance and quality of most individuals.

But strangely, Mizuki did not find such signs.

The difference in height, shortness, fatness and thinness is not a problem. The colorful hair and pupils don't bother the eyes, but what's the matter with a shark face? And those with many hands and feet, those with horns on their heads, those with bodies like rubber and noodles, those that turned into water and air...

Some of these are called blood following limits.

The bloodlines of foreign races like Otsutsuki are gradually integrated into human beings. As long as there is no awakening of the blood and the boundary or the phenomenon of reversion, they will basically not show anything different from ordinary people.

Why is it so difficult to eliminate the differentiated characteristics of human beings, and there is no sign of eliminating differences at all?

Until Mizuki understood the impact of the psychic contract provided by Miaomushan on Minato Naruto and Naruto, Mizuki finally found a clue.

Chakra is the culprit behind the diversity of human genetics in the ninja world.

After all, only a few people like Orochimaru and Mizuki who use biotechnology to actively adjust, can not affect the whole human beings, but ubiquitous Chakra can do this.

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

As for the variation due to other reasons, there are even more changes. The superficial changes in hair color, eye color, and skin color are not worth mentioning, but the blood line boundary formed by the fusion of chakra nature changes is not a trivial matter.

Melting, Ice, Boiling, etc., the accumulation of these hereditary characteristics from generation to generation will form a stable bloodline boundary or a family of secret arts.

"Chakra, is subtly accelerating the planning process of mankind! The one who walks in the forefront of mankind and leads 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 quality of human beings in the ninja world has greatly exceeded Mizuki's expectations.

There are also some side evidences that large-scale plagues are rarely popular in the ninja world, and there are not many types of deadly diseases for ordinary people.

On the contrary, the extremely talented blood ninjas like Uchiha Itachi and Kaguya Junmaro have a higher probability of developing incurable congenital diseases.

Chakra is not radioactive radiation, and the probability of inducing adverse mutations is extremely low. As long as there are no accidents, ordinary people will have little impact, but the probability of ninjas who often use chakra to perform ninjutsu is much higher.

...

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

Soon after returning to the village, Shui Mu got the latest investigation report from the entity clone - Gongzhi.

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

Since each entity avatar is given great autonomy, it is inevitable to make differentiated arrangements for the assigned tasks.

Like the fight with Penn Liudao not long ago, they were still side by side, but they usually do their own things and occasionally cooperate with each other.

Gongji is the person responsible for investigating the social structure and development direction of the ninja world, focusing on the relationship between ninjas and commoners, and the reasons for the separation of ninja villages and the secular society represented by the daimyo.

Since discovering some unusual signs of ninja-civilian relations two years ago, Mizuki has been trying to find the reason, but it is disappointing that he did not expect to get such a result after more than two years.

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

Gongzhi said earnestly,

"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 doubt, why the ninja world is like this, power does not match power, power, status, mastery Ninjas with absolute force have actually lost their secular power. This is not like religious organizations, because the progress of civilization has led to the weakening of theocracy. There are gods in this world, but the status of ninjas with extraordinary power is not high..."

"Um?"

This entry point is kind of interesting.

"Then what do you think?"

"I haven't made up my mind about the final conclusion, but after completing the report in your hand, I have some inspiration..."

"What is it?"

Mizuki asked with interest.

"We may have been misled by the memory of our previous life! The world where extraordinary power exists cannot be applied to the social phenomenon that all people are born equal, and the social phenomenon that needs to be divided into classes by rules."

"System, power, law of the jungle?"

"Not such a superficial thing."

The prince shook his head,

"Power is in oneself, not in society and weapons."

Gongzhi's words surprised Mizuki:

"You are denying the meaning of the existence of the order in the ninja world. This is an anti-social speech that is more cruel than the law of the jungle."

"Did I talk nonsense, think about it. How did Kaguya Otsutsuki clean the world, and then how did it manage the world; Nagato Collect-tailed Beast wanted to use absolute force to establish a "Kingdom of God" to rule the world, What is the difference between this and Kaguya Otsutsuki? Because Otsutsuki is an outsider? Or is Nagato more benevolent? When did Uchiha Obito and Uchiha Madara take the will of ordinary people in the ninja world to heart? Doing bad things with good intentions Just putting money on their faces, in the end, they're just for self-satisfaction."

"Think about yourself. You can't even believe in your clone. You never put the foundation of your power on others, but firmly hold it in your own hands. If you don't have the power you have now, what will happen?"

"Because I'm strong, I don't need to rely on any foreign objects, so..."

Mizuki thought about it,

"Even if there is no Konoha Village, I still stand at the top of the ninja world. The power belongs to me, and all social systems are just appendages that magnify the influence of power."

"You finally understand?"

"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 that."

There are multiple unrestricted personal force, and the possibility of forming the current state of the ninja world is too small. For more than a thousand years, except when Kaguya Otsutsuki and the Six Path Immortals were alive, most of the time, the ninja world was in the world. During the war...
