When he learned that Li Shimin had agreed to his marriage with Li Qi, Peaceang almost jumped up happily, but then he was a little shy and said, "It depends on his father and His Majesty to take charge." Then he ran out with a blushing face. This was the first time Li Xiu saw his son lose his composure, and he couldn't help laughing.

"Husband, do you really want Heianro to marry a beautiful woman?" Compared to Heianro's happiness, Yi Niang asked with some displeasure at this time. After all, as a mother, she really doesn't want her son to marry a woman with physical problems, even if the other party is a princess.

"Why are you here again?" Li Xiu couldn't help but say helplessly when he heard Niang Yi's words, "You have seen his son just now. A child who is usually so steady is shy because of this. You know the character of Heianlang the most. However, he looks gentle and respectful, but he is actually very independent. If we really force him to separate from Lizhi, he may really dare not marry him for the rest of his life. At that time, we can't force him to marry a woman he doesn't like, right?"

"What's wrong? Didn't your husband just be forced to marry me?" The lady in the air still retorted dissatisfiedly, and even used herself as an example. She and Li Xiu were really forced to get married. Although it was very awkward at the beginning, over time, their relationship became deeper and deeper. It was a typical example of getting married first and then falling in love.

"You..." Li Xiu felt amused and laughed when he heard the words of Yi Niang. After a moment, he said helplessly, "We are just exceptions, and our son is much more stubborn. You, the one who is a mother, must know more about this than me."

The lady in the air was actually just stubborn. Thinking of her son's appearance just now, she couldn't help but sigh and said, "Forget it, as long as Ping Anlang likes him, I, the one who is a mother, will not stop him. At worst, I will take him a few concubines in the future. However, the princess must get the princess' consent to take a concubine, and then I will discuss it with Lizhi."

"You have considered taking a concubine too early!" Li Xiu said laughing and crying when he heard Yi Niang's words. Ping Anlang and Lizhi were just about to get engaged, but Yi Niang was about to take a concubine for Ping Anlang, and she felt a little sorry for Lizhi.

"I almost forgot that Lizhi is a princess, and His Majesty also knows her physical condition. So when Lizhi comes, His Majesty will definitely arrange many dowry maids. These maids are generally of good origins and are all people around Lizhi. You can feel more at ease as a concubine, so as not to have any fighting in the future." The lady in the air didn't listen to Li Xiu's words at all, but instead thought carefully there.

When Li Xiu heard this, he slapped his forehead powerlessly. He picked up his youngest son Li Le and left the room so that he would not listen to Yi Niang's calculations about these things that were still unknown. By the way, he went to Princess Pingyang and Yuechan and told them about Ping'anlang and Lizhi's engagement. As a result, both of them were very happy and immediately ran to Yi Niang's place to help her prepare for the engagement.

Three days later, Li Xiu went to Zhongnan Academy to give a lecture as an appointment. Although he was knowledgeable and talented, the current students of Zhongnan Academy mainly mainly passed the imperial examination. In the imperial examination, Li Xiu's only good at the subject of Mingcai. In fact, as he introduced symbols into mathematical science, he also used mathematical symbols in the examination of Mingcai. This also made his book "Li Gongzi's Arithmetic" widely circulated. Almost everyone who wants to take the imperial examination of Mingcai has one.

The most difficult and most eye-catching imperial examination is naturally the Jinshi subject. In comparison, the Mingsuan subject is just a small subject, but the advantage is that the court has a relatively large demand for talents in this area, at least several times more than the Jinshi subject. Moreover, compared with the Jinshi subject, the Mingsuan subject is also easier to take, so many people regard the Mingsuan subject as a stepping stone to enter the officialdom.

So when Li Xiu came to Zhongnan Academy to give a lecture, almost all the students who wanted to get the Ming Case subject in the academy came, and even some students who didn't plan to get the Ming Case subject in the academy came. After all, it was a very rare experience to be able to listen to the famous Li Xiu's lecture. As a result, three or four hundred people came at the end. You must know that there are less than eight hundred students in the entire Zhongnan Academy. It can be said that half of the students in the academy have come, and this is because many students have other classes to take, otherwise more people will definitely come.

This is the first time for Zhongnan Academy to listen to the class together. The academy could not find a classroom where so many students could sit for a while. Finally, it simply vacated a large warehouse, which gave birth to a place to attend classes. It is worth mentioning that Xiao Yu and some gentlemen who had no classes today also came to listen to Li Xiu's class.

Li Xiu also prepared enough content. In the first half of the year, he mainly talked about students and listened to them, while in the second half, students were allowed to ask questions to increase the interactivity in the classroom.

The first half of the class was very smooth. Li Xiu often gave lectures to his children in the family over the years. In order to arouse the children's interest, he also taught boring maths and science. It is probably the first time that these students in the academy have heard such a class. After all, most of their husbands are tight-fitting and are serious in class. They never joke with the students, which also makes many people think that Li Xiu's class is very interesting.

In the second half of the questioning session, the students' emotions were also inspired by Li Xiu, and they raised their questions in their hearts to ask Li Xiu for advice. At the beginning, the questions of these students were normal, at least within the scope of calculations. However, I don’t know when the students’ questions actually started to get rid of the questions.

In fact, it cannot be considered a wrong question strictly. The questions raised gradually exceed the scope of mathematics. For example, someone asked how to measure the distance between the moon and the earth. This requires the knowledge of astronomy and mathematics. Thanks to Li Xiu's knowledge, these questions are not difficult for him. As a result, these students saw that Li Xiu would refuse everyone, and the questions asked later were even more outrageous. Some of them were not content in mathematics at all, but Li Xiu still answered them smoothly, which made the students admire and admire them.

After one class, all the students were impressed by Li Xiu's erudition, and Xiao Yu and others were even more impressed by it. Especially Li Xiu's way of teaching, he also had to write and draw on the blackboard while speaking to enhance students' understanding, which also made them feel like they were eye-opening and could also be used in teaching in the future.

In the following period, Li Xiu also went to Zhongnan Academy to give lectures every now and then. Every time, there were many listeners. Even some people who were not students of the academy were famous for their attendance. Some of them were students of Nanshan Academy. Although the two academies were competitors, Xiao Yu was very dignified. As long as the other party was willing to come, he would never drive the other party away.

The engagement matter between Heianlang and Lizhi was also under intense preparations, and the engagement date was also set. On the 20th day of the twelfth lunar month this year, it is said that it was a good day that the Imperial Heavenly Prison calculated for a long time. Moreover, this matter has been spread now, and it has attracted a lot of attention for a while. After all, one is the royal princess and the other is the eldest son of the important minister of the Tang Dynasty. The combination of the two is enough to cause a big and small shock.

It is worth mentioning that after Lizhi knew that she was about to get engaged, she cried with joy. It was only when Yizi told Li Xiu that there was one thing that was not good, that was, Lizhi was too shy and did not dare to see Heianro for a long time. Even if Heianro entered the palace, she would not see her. But this is good. Although engagement is different from getting married, it is a good thing for the two to reduce their meeting appropriately, so as not to cause gossip.

Li Zhi is one of Li Shimin's favorite daughters, and Peace Lang is Li Xiu's son. Coupled with Li Zhi's physical condition, Li Shimin attaches more importance to this marriage. Even if it is an engagement, he is preparing to hold a grand ceremony. Li Xiu has also prepared a very generous betrothal gift. Although the royal family is not short of this, it also shows the attitude of his family.

However, the last time Li Shimin went to Li Xiu's house, he was talking about not only the marriage between Ping Anlang and his two, but the most important thing was related to Li Chengqian. However, from Li Shimin's attitude at that time, Li Xiu had already discovered that Li Shimin would not agree with his suggestions. After this period of observation, Li Shimin did not unexpectedly.

Of course, Li Shimin did not completely agree with Li Xiu's suggestions. For example, he severely punished the villain and treacherous people around Li Chengqian, and transferred Zhang Xuansu, who was the most powerful, from the East Palace. Cen Wenben, Ma Zhou and others no longer went to the East Palace to discuss politics with Li Chengqian, but Yu Zhining, Kong Yingda and others did not move much.

Li Shimin also became more concerned about Li Chengqian. It happened that Li Chengqian and the first son of the Crown Princess were born some time ago. Li Shimin personally named Li Jue, and therefore had a banquet in the palace to celebrate the birth of the emperor's eldest grandson.

However, although Li Shimin took some of Li Xiu's suggestions, he had not done the most critical point, that is, the suggestion of letting Li Tai leave Beijing. He heard that Li Shimin had also considered letting Li Tai leave Beijing, but in the end he gave up his thoughts. The reason why Li Xiu knew so clearly was actually Cen Wenben personally told him, because Cen Wenben had repeatedly persuaded Li Shimin to let Li Tai leave Beijing. Although Li Shimin was moved several times, he finally regretted it.
