Runzhi was naturally very interested in this topic, so he only heard and said:

"In fact, the size of the population is of course very crucial, because this is the greatest wealth of a population, and the expansion of any territory and the strength of culture must be achieved by the size of the population in the final analysis. Especially when any race becomes powerful, it will definitely use various ways, so that its many populations can occupy every corner and every space under the firmament in various ways, so as to achieve the greatest degree of cultural replication and reproduction. In fact, the role of culture is to the greatest extent determined by the quality of its elite engaged in cultural creation. If any population wants to realize the immortality of its own population, that is to say, if it wants to realize a large number of replication and expansion of the racial island, it needs to do everything possible to extract material from nature, transform this substance into the flesh of the population, and in the process, unconsciously copy the experience and wisdom of the entire population to this body, which is what we call a newborn. Therefore, since ancient times, those emperors have tried every means to have children and increase the number of their concubines, which is actually increasing the chances of replication and diffusion of their own clans. That's because there is this contest of opportunities for replication not only among all human populations, but also within populations. Similar populations, often with similar memories and experiences, come from the more things are common to their ancestors, so among similar human races, this is the most likely object of mutual war between marriage and population. ”

Runzhi cleared his throat slightly, and then continued:

"The population of similar people, for example, for the southern natives of Annam, and the intertwined county migrants of the original Chinese tribe in the north of Annam, this is a typical similar population, from the outside, the two populations almost do not seem to be much different, but these two groups have different ancestral experiences and experiences inside, which is equivalent to the two populations are copies of two different people, and these two different people were brothers at the beginning. Legend has it that when Nuwa created the heavens, there were three main types of people created, and these three types were white, yellow and black. At first, Nuwa saw that the water was white, so she wanted to make all people white. At the beginning, when Nuwa was creating people, she was thinking, what color should she make? Later he saw that the color of the water was white, so he wanted all the people to be white. But then when he saw that the burning flame was yellow, it was so beautiful, and besides, she saw that the sun was so bright, and the sun became orange especially at sunset, and it was very beautiful, and at this time, she thought that yellow was the most beautiful color in the world, so she wanted to make everyone yellow. But on the seventh and last day of the creation of man, suddenly there was a crack in the sky, and lightning came down from the gap in the broken sky, and burned a piece of sawdust on the ground into black coals. When she saw this black carbon, she felt that compared with water and fire, black was actually a kind of embellishment, a little bit, like the jujube in the jujube cake, but it was a rare and necessary existence, so she added such a black group. It's just that after the population was created, the girl looked left and right, and didn't like it at all, so she pinched the black kind of people casually, and saw that this black was the easiest to get hot, so she mainly threw it on the equator of the world."

Xiaohe heard that it was easier to have wars between similar populations, and at this time, she suddenly felt a little frightened, so she asked:

"If you say that those similar populations are actually brothers from the beginning, then why do you say that these similar populations are more prone to war? Isn't that a paradox? ”

When Zheng Xie heard this, he laughed out loud and replied instead of Runzhi:

"It's an interesting question, so I'll answer it instead of an adult. In fact, why is it that those similar populations are brothers in the first place, and why are such similar populations often the most prone to war? Of course, there is a reason for this. It turns out that between similar populations, their memories and experiences are often very different, but their experiences, and all the wisdom of their ancestors, have the greatest compatibility in this similar flesh. Therefore, all races have tried to achieve the goal of reproducing and spreading their own races through war. For example, the most typical is Alexander the Great's crusade, and the main thing he conquered was actually the kind of race that seemed to be little different from himself on the outside, but there was a huge difference in cultural level. Any race. If you try to replicate and spread your own existence, the first choice is the nearest population similar to you. In most cases, a large number of populations, in order to replicate themselves, actually choose the closest race. Because they understand that for them, first of all, the coefficient of difficulty is minimized, and then the compatibility of the flesh is the greatest, and at the same time, they can maximize the efficiency of the replication of their own population, and they can maximize the possibility of replication of their own population and the scope of the existence of racial memory and culture. On this basis, these populations will try to achieve physical integration and spiritual integration with other races that seem to be very different both internally and externally. Because they are often intolerant of people who are very different from each other internally and externally, they often use the strategy of direct expulsion, even after occupying the territory of the other party. For example, if the Persian Empire occupies a piece of land in the Roman Empire, then if the people of the Roman Empire and the people of the Persian Empire, if the two are very different internally and externally, then the ordinary people of the two will not be willing to intermarry, then the inhabitants of the land must be expelled regardless of the occupation of the land. This phenomenon also occurred in the northern part of the Chinese Empire, where there was once a place called Haishenwei, and the land originally came from thousands of years of history since ancient times, and it was the inherent land of the Chinese Empire. But it was forcibly occupied by the Dasha Empire, and there was a huge difference between the people of the Dasha Empire and the people of the Huaxia Empire, and it was not easy for the two to intermarry, so the Dasha Empire directly drove all the people of the Huaxia Empire to the south, and all the people of the Huaxia Empire who remained were brutally killed. ”
