Chapter 1416

The Jiuli nationality followed the Chiyou tribe and lived here for thousands of years.

For thousands of years, the population has ranged from thousands to tens of thousands, or even hundreds of thousands. However, their tribe has always been married by close relatives.

In fact, these people do not know what close relatives are.

For example, in ancient times, many, even many princes and nobles married their cousins in this way, which naturally gave birth to many premature deaths, even idiots.

Now the same is true of the Jiuli tribe. Except for the marriage of internal close relatives, there is no marriage of those outside.

Over time, the tribal population has become smaller and smaller.

The tribal chief and elders don't know what the situation is, and the tribal witch doctors and wizards don't know either.

However, more and more people in the tribe are getting sick, which is still strange, which makes Mao and the patriarch pay attention.

This time, I learned that Xiao Chen came and specially asked Xiao Chen to see it.

"Next of kin marriage?" Mao asked the patriarch strangely.

The so-called close relatives refer to the common blood relationship among three generations or within three generations. If they intermarry, it is called consanguineous marriage. Both of them have too many similar genetic factors, and their offspring cannot produce variation from them, and harmful genes will pass it on to their offspring.

If this gene is inherited in an autosomal recessive manner, its children may develop disease because they are mutant homozygotes. Therefore, inbreeding increases the risk of some autosomal recessive diseases.

Mao let the patriarch certainly don't know.

After hearing Xiao Chen's explanation, Mao asked the patriarch to say, "Dr. Xiao, do you mean you can't get married within four generations?"

"Yes, you'd better not get married. I think you'd better marry the Miao people outside. The young women of the Miao people outside can marry in, and the young women here don't marry out, so it won't lead to close relatives, and harmful genes are easier to pass on to future generations. "

Marry the women here?

Let the women outside marry in again?

Tribes and others never seem to think about it.

Now they still live a life of slash and burn cultivation and isolation from the world. If they marry like this, can't they maintain the traditional culture?

Mao asked the patriarch to frown.

"Dr. Xiao, is there any other way besides this?"

"No. Otherwise, there will be fewer and fewer people in your tribe, and those of your descendants will have more and more genetic diseases and more pain. It must be harder to suffer from pain. "

Xiao Chen feels that the nine Li people can keep their traditions, such as good essence culture can be preserved, and they will not be abandoned.

Like the marriage of close relatives, it must not work in Xiao Chen's opinion.

In fact, this kind of situation also exists abroad. There are such tribes in the Amazon jungle. They live the same life as the Jiuli nationality, and finally disappear slowly, because there is no one.

No one, naturally there is no tribe.

"Dr. Xiao, what do they do?"

"According to their symptoms, I give them medicine to drink. Some can be cured, but others can't be cured."

Xiao Chen knows that his medical skills are very good, even in the late stage of cancer. As long as he wants to treat them, he can be completely cured.

However, this requires mysterious medicine and needs to pay a price.

Strange diseases like these in front of us.

Many did not exist, but now they appear in the ordinary people of these tribes, which is caused by their close relatives' marriage.

Xiao Chen gave them prescriptions one by one and asked them to buy at the small town drugstore outside.

In the mountains, although many can be used as medicinal materials, decoct medicine soup and drink it.

However, in fact, we can't have all the herbs here. We still have to go to the drugstore outside to buy them.

Maybe it was because of what Xiao Chen said. Mao asked the patriarch to meditate and asked people to entertain Xiao Chen. When they went to a wooden house, Xiao Chen had seen master Miao.

"Master." Xiao Chen greets master Miao.

Master Miao is still very satisfied with Xiao Chen, a young man.

The other party has good medical skills, medical ethics and personality.

Although the other party is not Miao, his talent is still very good in all aspects of witchcraft.

"Just now Mao asked the patriarch to invite you over?"

"He asked me to see the patients of his tribe."

"Have you seen it?"

"Look, some are cured, some are difficult to treat."

Master Miao understood when he heard Xiao Chen's explanation.

In fact, thousands of years ago, the Miao and Jiuli were not the same nation, but later, due to the regional environment, the Miao slowly contacted the outside world, while the Jiuli stayed here and were willing to accept the outside world.

"When the Jiuli nationality had the largest population, there were actually hundreds of thousands of people. Later, it gradually became less and less. Until now, there are only thousands of people left."

On the contrary, there are more and more Miao people outside.

Xiao Chen was surprised that there was only a small population left.

"It seems that it's better to let them contact and communicate with the outside world. Otherwise, if it goes on like this, thousands of people will be lost."

Master Miao nodded.

In fact, they are similar to Jiuli culture in all aspects, and even many ancient characters can be understood by Miao people.

"Master, when shall we go under the cemetery again?"

"Tonight."

Go in tonight?

Xiao Chen felt that it was safer to go in from another port.

If you go in through the front door, Xiao Chen doesn't know what's going on inside.

Last time, I met the double headed snake and the layout of gold, wood, water, fire and earth. It can be said that it was only after five passes and six generals.

Of course, these thousands of years, basically can not get in or out.

He wondered why master Miao had to go in?

"Shifu, it's too dangerous to go in. If you want to find something, let me go in instead of you."

Xiao Chen is also worried that master Miao will die if he goes in like sister Sang's master.

"I must go."

Master Miao said that. Xiao Chen didn't ask any more questions.

When Xiao Chen and sang and Mo Xiaowan went to another wooden house to have a rest, time passed quickly unconsciously.

In the twinkling of an eye, at more than five o'clock in the afternoon, Xiao Chen felt that it was dark here.

It may be that there are many trees near here, blocking the sun.

Xiao Chen and others and master Miao were called to maorang clan leader.

At this time, in addition to Mao rang, Xiao Chen also saw several old people, who should be the elders of the tribe.

"Dr. Xiao, this is our big elder, two elders, three elders, four elders and five elders."

When Mao asked the patriarch to introduce them, Xiao Chen stood up and greeted them one by one, whether they were elders or not, but they were already old people, and Xiao Chen should respect them.
