The footage taken by the drone at high altitude is particularly shocking to the ancients.

Coupled with the worry-free editing, modern people are enthusiastic when they watch it, let alone the ancients.

"That's a lot of food."

"It's good."

"Flying in the sky to watch?"

"The fairy took us to see it in the sky."

"I didn't expect it to look like this in the sky, people look so small, like ants."

As the camera progresses, everyone sees a variety of crops.

Someone in the canopy explained: "Our country has a large population, and in order to solve the problem of food and clothing, the country ......"

The immortals in the canopy first talked about various high-yield crops, then began to talk about agricultural production in ancient times, and even talked about the role of the 400 mm precipitation line in the rise and fall of dynasties.

Qin Dynasty

Qin Shi Huang listened very carefully.

When he heard the canopy talk about how the shift of the 400-millimeter precipitation line affected the rise and fall of a dynasty, the calmness on his face cracked inch by inch.

It turns out that this is the case?

He listened more carefully, and wanted to hear if the canopy would teach him how to do it without being affected by the precipitation line.

Then, he heard the immortals in the curtain mention the agricultural production of the Qin and Han dynasties, and wondered in his heart that this Han should be the dynasty after the Qin, but he didn't know how the Han system was, and how many years did this dynasty last?

But then he didn't think about it.

Because Tianmu began to teach how to farm in order to produce more food, and also taught how to make agricultural tools, such as the invention and application of the curved plow, such as the application of waterwheels, and the ridge tillage method.

Not only Qin Shi Huang was listening, but Emperor Wu of the Han Dynasty and Li Shimin were also listening very carefully.

Finally, Tianmu talked about breeding.

The previous ones that everyone can still understand, but when it comes to breeding, many people don't understand, and they don't know what's going on.

What kind of hybrid rice is that?

What is called monoecious, self-breeding, I hear it clearly, but why don't I understand?

But there are also those who get it.

Three dynasties, three emperors through the ages and one emperor ordered at the same time: "Pass the order, send people to recruit talents and talents in various places, and send anyone who understands the breeding method in the canopy to the capital......"

Soon, the breeding method was also finished, and when everyone breathed a sigh of relief, they saw a carefree smile appeared in the sky.

"Well, when I saw the explanation of the breeding method just now, I thought of one thing, and that is the matter of marriage between close relatives."

"We all know that everyone's genes are defective, if close relatives get married, it will be easy to pass on the same disease genes obtained from ancestors to the next generation, there is a greater possibility of giving birth to deformed children, or the children born are sick and weak, and may not be able to give birth to children, therefore, our country's law stipulates that close relatives are not allowed to marry, what do we mean by close relatives? Usually we refer to close relatives within five generations, or collateral relatives within three generations. ”

Speaking of this, Wu Wu also took out a picture on which the direct and collateral relatives were indicated.

The direct family understands it very well.

After all, in ancient times, the same clan and surname were not married.

But the side chart has made many people's faces change dramatically.

"Can't my aunt and uncle get married? Neither can an aunt or cousin...... Are these all close relatives? ”

"I said, there is a young couple in our village who are aunts and cousins, and they haven't given birth to a son and a half daughter after five years of marriage."

"Why haven't I heard of anyone who married and gave birth to a deformed child?"

"You are stupid, if you really want to give birth to that kind of child, you must have dealt with it secretly, who will shout that everyone knows?"

"Oh no, my uncle's cousin and my aunt's cousin are about to get engaged, I have to hurry up and say it, I must not let them get married."

Liu Che's expression changed greatly when he saw this.

He thought about his marriage to Chen Ajiao.

The two have not had children since they got married, and for this reason, Gillian gradually became crazy......

Now it seems that not having children may be fine for both of you.

What do you have to think of and say: "The marriage of close relatives is very harmful, and it has also caused many tragedies, for example, Emperor Wu of the Han Dynasty and Empress Chen are close relatives who married, so that the two have no heirs, and the famous Habsburg family in European history perished due to the marriage of close relatives, ending the dynasty that ruled for 640 years, and the Japanese kingdom is also about to die because of the marriage of close relatives." ”

Emperor:......

Although he already knew it in his heart, Tianmu said it in front of the world, which still made him uncomfortable.

Chen Ajiao in the Nagato Palace began to laugh wildly when she heard this, and after laughing, she cried.

"That's the case, I shouldn't have married him in the first place, it turned out to be ...... Mother, Gillian regrets it. ”

Qin Dynasty

When Qin Shi Huang heard about Emperor Wu of the Han Dynasty, he speculated that it must be an emperor of the Han Dynasty, and this emperor was unable to have children because he married his cousin.

He thought of his palace again.

Most of the beauties in his harem are nobles from the Six Kingdoms, and they have no blood relationship with him.

The calculation was understood, and Qin Shi Huang breathed a sigh of relief, and at the same time secretly laughed at the Emperor Wu of Han.

deserves it, who let his ancestors take away the Qin Dynasty.

Datang

Li Shimin thought that he and Empress Changsun had discussed marrying his eldest daughter to the eldest grandson's family, and he was secretly glad that this matter was just discussed, and he had not told Changsun Wuji yet.

At the same time, he is also secretly vigilant, thinking that when he marries his children and in-laws in the future, he must inquire about the other party's kinship, and there must be no such thing as close relatives getting married.

Some of the ministers of the DPRK and China had dark faces, and some were secretly rejoicing.

If you have a bad complexion, it is based on kissing and kissing, and close relatives are married.

Secretly glad that the family matter has not yet been negotiated.

The people in the three dynasties were even more noisy, and they almost turned the sky upside down.

Many people who are close to each other hurriedly ran to their in-laws' homes to ask for peace.

Before the big mistake is made, it is better to let the children separate as soon as possible, and marry each in the future, than not to have children, or to give birth to sick and weak children.

The map of the European royal family began to be released on the canopy, and when they saw the diseases shown in the picture, the people shouted: "You can't get married with close relatives, if anyone wants to kiss and kiss, we have to persuade you." ”

"You see, such a big royal family is extinct because of close relatives, we can't make such a mistake."

After talking about the dangers of close relatives getting married, today's live broadcast is basically coming to an end.

She put away the projection equipment and said with a smile: "Family, that's all for today's live broadcast, and the next live broadcast will be in three days, everyone." ”

At the end of the live broadcast, the whole person was a lot more relaxed.

She thought that Li Le said that she was going to travel, so she lay on the bed and took her mobile phone to read the travel guide.

Well, where are you going to be the first stop when you go out?

Worry-free immediately thought of Xi'an.

Now her live broadcast room has connected the three time and space of Qin, Han, and Tang, well, Wang Baochuan's plane is actually the Tang Dynasty, even if it is not the official history of the Tang Dynasty, it is also the Tang Dynasty.

The capitals of these three time and space are all in Chang'an, which is now Xi'an.

Then go to Xi'an, and let the ancients take a look at the modern city of Xi'an.
