Time flies, time flies.

The happier the time, the faster it will drain.

In the blink of an eye, ten years have passed.

Emma Linko has become a thoroughly middle-aged man and has begun to enter the stage of old age.

The three children have also grown up, although they are all sensible, but there is a big problem in front of Ji Ran, which bothers her very much.

Men should get married, and women should get married, but apart from a few members of their family, where are there outsiders here?

Franks and Cao Kesi are brothers, and they have always had a good relationship, but recently they have become jealous of each other because of Elena.

Obviously, both brothers like Alena very much, and Alena is indeed a good girl, she looks a lot like Ji Ran, and even more beautiful than Elena.

She is ingenious, has learned all the skills of Ji Ran, and is a beautiful girl who is loved by everyone.

Both Franks and Caox liked Alena and felt that they were better suited to her.

However, they didn't know that in fact, none of them were Elena's most suitable ideal object, because they were brothers and sisters, sisters and brothers.

Biological brothers and sisters in a family are not allowed to be together.

Although in this kind of uninhabited hot spring valley, the laws of the normal human world do not apply, and no one can really punish them, Ji Ran still doesn't want to break such human rules.

After all, they are family.

Emma Linko, on the other hand, is diametrically opposed to Ji Ran's opinion, he believes that the conditions here are limited, and their children should not be bound by the laws and regulations of the normal human world.

If Franks and Caox don't unite with Shalena, then their family's bloodline will be cut off, and in a few decades, this place will become a wilderness without people, which is absolutely unacceptable to Emma Linko.

Emma Linko not only agrees with Franks and Caox's ideas, but even feels that Elena, as her daughter, should contribute to her family, not only to communicate with Franks and Caox, but also to create more blood and life for the family as much as possible, so as to make the family more prosperous and make this beautiful valley a real paradise and paradise.

In order to convince Ji Ran, Emma Linko also deliberately moved out of some special dynasties in history, some dynasties are intermarriages between royal families, most of them are elder brothers marrying their own sisters, or sisters marrying their own younger brothers, so that the blood of the descendants will be considered more pure.

In fact, those dynasties did not exist for a short time, some even as long as hundreds of years.

In other words, although consanguineous marriage will have all kinds of genetic defects, it is not absolutely sensational, as long as the population of offspring is sufficient, and then the method of cross-breeding offspring on a larger scale can actually eliminate some genetically defective members through natural selection, and finally leave a group of offspring as healthy as normal people.

In fact, in ancient times, human beings were bred by a group of Homo sapiens living together in a small population after intermarriage with each other.

This is not difficult to understand, because people are all descendants of parents, and parents come from grandparents and maternal grandparents, and further back grandparents and maternal grandparents come from great-grandparents and maternal great-grandparents, that is to say, our existence, in the generation of the fathers, we need two people, the father and the mother, to the generation of the grandparents, we need four people, the grandparents and the maternal grandparents, and if we push forward, we need eight people... Sixteen people... Thirty-two people...

By analogy, if we push forward 33 generations, we will have more than 8 billion ancestors, which is almost the same as the population of the world today.

However, thirty-three generations ago, it is estimated that there is only about a thousand years from today, that is, about the Northern Song Dynasty, not to mention the Northern Song Dynasty at that time, even the world may not have hundreds of millions of people.

At that time, when the great national integration had not yet begun in an all-round way, let's count our ancestors as pure Chinese, then, according to the population of 120 million people at the peak of the Northern Song Dynasty, the average number of times that everyone appeared in our genealogy book during the Northern Song Dynasty was at least 70 times.

Of course, this does not include the fact that some of them have no descendants, or their descendants have no descendants later, and if these cases are also removed, then in 1018 AD, each Song Dynasty appeared in our genealogy more than 100 times on average.

What does this mean?

That is to say, it is very likely that the son of your thirty-third ancestor is your thirty-second great-grandfather, or your thirty-second great-grandfather, or your thirty-first great-grandfather, because one of his descendants may reproduce quickly, and a few generations may be a generation.

That is to say, no matter how distant your generation marries a wife who is related by blood, or marries a husband whose blood relationship seems to have nothing to do with it, but the blood in your body has actually been repeated countless times in history.

If you can go back to 3,000 years ago, when all the people in the world were your ancestors, they were all your relatives, if you compare blood relatives with them, they are all your relatives, do you say that it is magical?

If we go back even further, we can even find a common ancestor whose name will appear in the genealogy of all human beings, that is, we are actually descended from the same ancestor.

As we all know, the earlier the population, the smaller the number of ethnic groups, because it is caused by extremely harsh natural conditions, so that even a very small family can develop into a large population if it reproduces in large numbers.

It is in this process of repeating the bloodline that human beings have developed step by step.

The reason why there are many people who are very different now is that most of them are acquired in different environments, and there are differences in adaptability.

Emma Linko wanted to explain this truth to Ji Ran, but limited by his ability to express, Ji Ran was confused and confused, but after calming down, it was not difficult for Ji Ran to understand what Emma Linko wanted to express.

Although in terms of racial reproduction, inbreeding is also an inevitable choice when necessary, but in Ji Ran's heart, there will still be a big hurdle that is difficult to overcome.

Is it for the sake of the race, and trampling on the rules of civilization accumulated by mankind for thousands of years?

Or is it to let one's genocide be carried out in order to abide by the rules of human civilization?
