Chapter 90 The dangers of popular science!

Xu Tian raised questions one after another, Li Shimin, Li Ji, and Cheng Yaojin all stared at Xu Tian and Changsun Wuji with wide eyes, while Li Changle looked at Xu Tian with a strange expression.

The three of them were puzzled, why did Xu Tian suddenly ask this question?

Does this have any connection with Changsun Chong and Changle’s marriage?

"In ancient times, princes died young, and many nobles died young, but fewer children of landlords died young. In ordinary people's families, there were also fewer ones who died young!"

Changsun Wuji said coldly.

"All of them are humans, why do princes die prematurely? Few children of noble families can become adults. On the contrary, they are the descendants of landlords and gentry. Most of them are very healthy. In ordinary people's families, few children die due to illness. Have Uncle Zhang ever thought about why this is?"

Xu Tian asked in a deep voice.

"Hmph! Of course, it is because of the imperial power and heavenly destiny. The prince was born to uphold the fortune of heaven. Some people could not bear such luck and died prematurely, which is also normal."

"The same is true for aristocratic families. The larger the family, the more lucky people need to inherit the family business. Those without luck can only be a foil!"

Changsun Wuji said coldly.

If someone else dared not say this, but he dared!

Just because his nephew was Li Chengqian, the crown prince of the current dynasty, Li Shimin could be dissatisfied with this, but he would never dare to blame him for this!

At this time, Li Shimin frowned and was indeed angry. According to Changsun Wuji, his son, except for Li Chengqian, shouldn't he die!

"Haha! Uncle Zhang, you are wrong, and you are outrageous! You are at the extreme!"

"As the saying goes, I don't say that my son is so powerful that he is so chaotic. We scholars don't believe in these things. The reason why the prince died prematurely was because of the marriage between relatives!"

Xu Tian said with a smile.

"kindness?

Marriage between relatives! A row of nonsense! They are all human beings, why can’t relatives marry?

Why do children born in marriage die prematurely?”

Changsun Wuji said coldly.

Li Shimin, Li Ji and Cheng Yaojin all knew Xu Tian’s ability and knowledge. He did not directly doubt this matter, but instead pricked his ears and waited for Xu Tian’s explanation.

At this time, Xu Tian also had a difficult time. The theory of genes is complex and complex. Even people from later generations rarely understand it, let alone the Tang Dynasty. How should he explain it to them?

Have it!

Xu Tian suddenly thought of how to explain and said, "Uncle Zhang, I would like to ask you, do your brothers and sisters have the advantages you have, too?"

"Haha! As the saying goes, dragons give birth to dragons, phoenixes give birth to phoenixes, and children born to rats can dig holes. Since they are my fellow-birth compatriots, they naturally inherited the advantages of their father like me!"

Changsun Wuji sneered and said, thinking that Xu Tian’s problem is very young!

"Okay! Since Uncle Zhang said that, it means that Changle's mother and Uncle Zhang have the same advantages. I'm fine if I say that, right?"

Xu Tian asked in a deep voice.

"Of course this is true. Changle's mother is my own sister. She has been like me since childhood. She is extremely smart and proficient in everything from chess to calligraphy and painting!"

Changsun Wuji said proudly.

"Since that's the case, brother Zhang and Changle also have almost the same advantages?

The only difference is that Changle has the advantages of my father-in-law, while Brother Zhang has the advantages of Aunt Zhang, right?”

Xu Tian said again.

this……

Changsun Wuji felt that what Xu Tian said was a bit difficult to talk about, but he could also barely sort it out.

"That's right!"

Changsun Wuji said.

"If Uncle Zhang can understand these, this matter will be easy to explain. First of all, we can be sure that a couple's children will inherit the advantages of both husband and wife, that is, they will take half each to form a complete person."

"This means that if the advantages of two people are different, the children born will have the advantages of both parties! And they will be better than the younger generation."

"But if the advantages of both husband and wife are the same, then if the children born have half of their advantages, isn't it highly likely that this half will be repeated!"

"In other words, he inherited only half of his strengths. Is this still a complete person?"

Xu Tian first explained, then asked.

this……

Li Shimin, Li Ji and Cheng Yaojin shook their heads at the same time. If others inherited the advantages of both parties and their children only inherited half of them, they would definitely not be considered a complete person.

"This...of course it doesn't count!"

Changsun Wuji said in a deep voice. At this time, his expression had become solemn.

"Okay, now Changle and Brother Zhang have half of their advantages, which are the same. This means that if they get married, the children they give birth to have at least 30% chance of inheriting the same advantages. Therefore, for the health of their offspring, Changle and Brother Zhang must not be together."

Xu Tian said in a deep voice.

hiss!

After Xu Tian's explanation, Changsun Wuji took a breath of air and Chong'er and Changle were together. Not to mention 30%, even if there is a 10% chance of giving birth to an incomplete child, he is unwilling to do so!

"This... a virtuous son-in-law, what will it become if a person is incomplete?"

Li Shimin asked.

Li Ji, Cheng Yaojin, Changsun Wuji, and even Changsun Chong stared at Xu Tian with his ears.

"A person is not necessarily physically incomplete, or it may be because his body is born weak and sickly, not as strong as others, or he may be a fool, not as smart as others, or even born with poor ears, poor eyes, and poor legs and feet. These are all!"

Xu Tian explained.

"By the way! Most princes are born weak and sickly, and this history is recorded!"

"There are many children in noble families and noble families. Most of them are weaker than those in ordinary people's families. It turns out that this is the reason!"

"Generally speaking, the most capable people have more poor families. Is this the reason?

But few nobles from aristocrats have passed on their inheritance for more than five generations. Is this the reason?”

...

Li Shimin and others suddenly realized the serious consequences of getting married in close relatives.

When Xu Tian saw that all four of them understood, he not only nodded with satisfaction, but although he was an ancient person, he was an intellectual after all, and his ability to accept new things was stronger than that of ordinary people.

"So, if the two families are related, wouldn't they be in-laws!"

Li Shimin suddenly realized a problem.
