Li Shimin and Changsun Wuji were both looking at Li Xiu, which made him touch his face, thinking to himself whether he had any flowers on his face, but even if he had flowers, it would be uncomfortable to be stared at by two big men like this.

"Your Highness, what's wrong with you?" Li Xiu was stared at by Li Shimin and his whole body was chilled, and finally he couldn't help asking.

"Well, this..." Li Shimin actually showed a embarrassed expression at this time, then turned his head to look at Changsun Wuji, signaling him to explain to Li Xiu, which also made Changsun Wuji look helpless. The lower-ranking person could not refuse the orders of the higher-ranking person.

"The Prince Li, this is actually the case. In a few months, Your Majesty will abdicate the throne to Your Highness. However, Your Majesty has long felt that the laws of our Tang Dynasty are somewhat insufficient, so he ordered me to recompile a law. Although it generally follows the original laws, in some places, we try our best to check for omissions and make the laws of our Tang Dynasty perfect!" Changsun Wuji explained immediately.

"The memorial in the hands of the prince is your newly drafted Tang Dynasty law?" Li Xiu seemed to understand something when he heard this, but it seems that this matter has nothing to do with him, right?

"The Tang Dynasty law cannot be written in one piece of paper." Changsun Wuji smiled and continued, "The memorial was only an addition to some omissions in the law. It was written by memorials for a long time with several people who were proficient in the law. The others were nothing, but one of them was related to the prince-consort!"

"Oh? What law can be related to me?" Li Xiu blinked and said. He couldn't think of any law that would be related to himself, a lazy idle person?

"The same surname is not married!" Changsun Wuji stared at Li Xiu's eyes and said.

"What time has it been? Why would anyone propose such a law?" When Li Xiu heard the four words that Changsun Wuji said, he stood up in anger and said.

The so-called marriage of the same surname was indeed a taboo in Han marriage, but note that it was just that there was this law before the Han Dynasty, but after the Han Dynasty, there were too many people with the same surname. Therefore, although there was such a saying among the people, the court no longer included this article in the law, and many places no longer abide by such customs. For example, in the past, the Sui Dynasty was not in the law. Princess Pingyang joked about this matter.

"Well, this... the same surname does not marry according to the ancient system. Some customs and taboos left by our ancestors also have certain reasons. As the orthodox Central Plains, our Tang Dynasty naturally also has to follow the ancient system!" At this moment, Li Shimin suddenly said something, and then spoke seriously.

Li Xiu was stunned when he heard Li Shimin's words, and then he understood the implicit meaning in his words. The origin of Li Shimin's family was a bit complicated. Some people said that they were Xianbei people, while others said that they were Xianbei people. Anyway, no matter which statement, it means that they had the blood of Hu people, which caused a lot of trouble when the Tang Dynasty was established. For this reason, Li Yuan also found himself a Taoist ancestor, claiming to be a descendant of Lao Tzu. However, the more this happened, the more it meant that they were guilty.

Now Li Shimin's so-called following the ancient system is actually out of the same mentality. People who secretly slandered them said that they were Hu people, so he followed the ancient system of the Central Plains, and even picked up the ancient system that had been abandoned for hundreds of years. As a result, Li Xiu just hit the gun.

"Actually, the princess and the princess are not a problem. After all, you have been married before and will not be affected by this law, so the princess doesn't have to take it seriously!" At this time, Changsun Wuji suddenly spoke, as the saying goes, "Li Xiu is in this situation."

"That's not right. This law is wrong, and may even affect an important foundation of the Tang Dynasty, so it must be revised!" Li Xiu did not appreciate it at all. Instead, he retorted that he and Princess Pingyang finally got together, so he would never give anyone any reason to attack, not to mention that no one might say anything in the officialdom. Now he said that he would not blame him, but who knows if anyone would make any contribution to him in the future?

"Oh? Why did you say that?" Li Shimin was already a little unhappy at this time, but he still asked patiently.

"Your Highness, the so-called marriage of the same surname does not make a living from a medical perspective. Because if a man or a woman with blood ties gets married, the chance of giving birth to a child with congenital diseases in the future is much higher than that of other couples. However, blood ties are also different. Relatives within three generations can be called close relatives. This close relative must not get married. On the one hand, it is contrary to human ethics, and on the other hand, it will also give birth to a child with congenital diseases."

When he said this, Li Xiu paused for a moment and continued, "But as long as there are three generations, the blood relationship will be much farther, and the impact of getting married with a man and a woman is not very big. In addition, cousins ​​are popular in our Central Plains, which is actually a close marriage. The children they give birth to in the future are likely to have various congenital diseases, and women are likely to cause the death of children and mothers during childbirth!"

When Li Xiu heard Li Xu's novel explanation of marriage with his close relatives, Li Shimin and Changsun Wuji also showed a surprised expression. They did not expect that the ancient saying passed down actually had such a saying. After a while, Li Shimin then said: "Li Xiu, according to your statement, it is not wrong to not marry the same surname, and it is even a bit imperfect. Why do you say it will affect the foundation of my Tang Dynasty?"

"Your Highness, I would like to ask you what the foundation of a country is?" Li Xiu did not explain immediately, but asked Li Shimin.

"Is it basic?" Li Shimin lowered his head and pondered for a moment when he heard this, and finally raised his head and said slowly, "The most basic thing of a country is naturally the land and the people. Both of these are indispensable, otherwise the country will not be a country!"

"Yes, the foundation of the country is land and population. Our Tang Dynasty has a vast territory, the coast of the East China Sea and the border of the Western Regions, almost all of which are under the control of our Tang Dynasty. However, such a vast land has greatly reduced its population due to the previous wars. In order to increase the population, the court forced young men and women to get married on the one hand, and attracted fleeing from the mountains and forests, and even regarded the population as an important part of the assessment of local officials."

When Li Xiu heard Li Shimin and Changsun Wuji mentioned the population, Li Shimin and Changsun Wuji seemed to understand something at once. At this moment, Li Xiu continued to say: "Although there are quite a lot of fugitives in our Tang Dynasty, the number of people in the Central Plains has dropped significantly after the war. Therefore, it is the right way to really increase the population and encourage childbirth. However, if the law of not marrying the same surname is implemented, it will cause a serious blow to those big surnames. For example, Wang, which claims to have millions of people. If marriages of the same surname are prohibited, there will be fewer people who choose husbands or wives at once. If marriages of the right age are not allowed, and those men and women of appropriate age choose husbands or wives will be unable to get married in time. How can we ensure childbirth and population?"

"This..." After hearing Li Xiu's words, Changsun Wuji was speechless for a moment. Some people had previously proposed not to marry the same surname. They only considered the benefits brought by politics, but did not expect the impact on ordinary people. This is also a common problem for many noble officials, because they only look at the problem from their own perspective. After all, they don't have to worry about their children getting married.

Li Shimin also showed a meditative expression at this time. The orthodoxy of the Tang Dynasty was indeed important, but the population growth was also important. Not to mention anything else, he is now ambitiously preparing to destroy the Turks in the next few years, then pacify the Western Regions and the South, and Goguryeo, etc. Although these small countries are not as powerful as the Tang Dynasty, they still feel threats to themselves, and even make him feel like they are stuck in his throat.

However, war requires population, and the national strength to support war also requires population. It can be said that if there is no population, his ambitions can only be in vain. This is also the main reason why he has been introducing a policy of rest and recuperation during this period.

"Li Xiu, what should you do according to your wishes?" Li Shimin thought for a long time, and finally raised his head and asked Li Xiu.

"It's very simple. Modify the laws related to marriage, such as changing the same surname to a close relative without marriage, and then specify in detail what belongs to a close relative, such as parents, siblings, cousins, cousins, etc., and also increase the age of a woman when she gets married..."

"This is not right. Since you want to encourage childbirth, why should you raise the age of a woman's marriage? Wouldn't this reduce childbirth?" Before Li Xiu finished speaking, Changsun Wuji interrupted. It is undeniable that his talent is definitely above Li Xiu, but the gap in the times cannot be made up with his talent, which is also Li Xiu's biggest advantage.

"Brother Changsun, you don't know. From a medical point of view, women are fully qualified to have children after the 18th. However, most women now get married and have children on the 14th and 5th. This will seriously harm their bodies and will not be easy to get pregnant in the future. And it is also easy to have one corpse and two lives during childbirth. Even if the child is born smoothly, the child may lead to various diseases due to congenital deficiencies. However, if you have another child after the 18th, you will avoid these problems. Therefore, from a distance, increasing the age of a woman's marriage can increase more people!"

When it comes to giving birth, Li Xiu also seemed a little excited. Did the lady in the clothes really scare him before? Moreover, there are often women who die of difficult labor in the countryside. Most of these women are young and may still be in junior high school in later generations. Li Xiu felt uncomfortable every time he heard this, so he took this opportunity to mention it.

When Li Shimin heard Li Xiu's words, he couldn't help but show a contemplative expression, as if he was unable to make up his mind for a moment. After all, although what Li Xiu said makes sense, if he really wants to implement it, he needs to face great resistance. Not to mention anything else, just increasing the age of a woman's marriage is not something that can be solved by a decree, so he was also hesitating whether to accept Li Xiu's proposals?
