It was already noon when Li Mu came out of the palace. Li Shimin's enthusiasm for hot air balloons was extraordinary and he had to let Li Mu tell him the principle. Li Mu had to talk about it, starting with Kongming lanterns, then heat expansion and contraction, and then to the basic structure, materials, etc. of the hot air balloon, which made him dry and dry.

Li Shimin is a good student. He listens seriously and is very humble when asking for advice, but he is a little stupid. But this is not his fault. Although Li Mu has worked very hard to explain some principles of physics so easy to understand, Li Shimin has no foundation in physics after all, and he has no imagination in his mind to cooperate, so he naturally has to understand it slowly.

Fortunately, the hot air balloon is not complicated at all. Li Mu's gestures and explanations were considered popular science for Li Shimin.

After leaving the palace, Li Mu did not rush back, but went straight to the Duke of England's Mansion. Yesterday he did not get the hot air balloon, did not fly over the Duke of England's Mansion, nor did he see the scene of Li Siwen getting married. As his elder brother, Li Mu felt a little disgusted. Of course, he would come to the door and have a wedding wine today.

But unexpectedly, Li Mu came to the Duke of England's mansion and was out of stock. The concierge told him that the family got up early and rushed to the valley outside the city.

This matter was so troublesome that Li Mu had to rush out of the city. After a long journey, he finally saw the gate of his own courtyard.

The carriages could no longer be stopped on both sides of the road in front of the door. The shadows were all over the place. Li Mu saw it from afar and the flowing mat was put on again. It was obvious that officials from all over Li Siwen who had not arrived in person came to give gifts.

Li Siwen was hospitalizing for him. When he saw Li Mu coming back, he threw away the wine pot in his hand and ran over, shouting, "Brother, have you come down from the sky? Why did you get up? Take me around!"

Dugu Jiu followed closely behind, his eyes were also bright. Although he had no words, his meaning was already very obvious.

Li Mu got off the horse and said, "Isn't it just flying? It's a small matter. When I have time another day, I'll make another hot air balloon and take you all around."

"Don't go another day!" Li Siwen said anxiously: "Let's fly after dinner? Where is the carriage? Why didn't you bring it back?"

"It's burned!" Li Mu walked into the yard, and while walking, he told several people about the experience of "Hot Air Balloon No. 1". Li Siwen immediately felt regretful and murmured: "I'm going back to Dingxiang the next day, and it seems that I can't fly."

Li Mu stopped and frowned and said, "I'll leave the next day? I'm so anxious? Your Majesty asked you to leave? I'm too unkind to tell him!"

Li Siwen shook his head and said, "Brother, it's not what Your Majesty meant, it's me that I want to leave myself."

"It's been a month since I left Dingxiang. Every tree and grass in that city was built by me with people. Although there are no strong enemies nearby, I don't have to worry about anything going on, but I still think about it. I discussed with my father-in-law yesterday, and Xiaoyu will accompany me. Tomorrow I will accompany her back to the door, buy some things, and leave the morning after tomorrow."

Li Siwen smiled, with a few less hippie smiles, a lot more sorrow, and his eyes were slightly red: "Brother, I'll leave this time, and I'll meet again next time, it will take a year later-"

"It's not that long." Li Mu waved his hand and said, "After I'm going to the Zhang family to pick up your sister-in-law, and I will definitely pass by Dingxiang at that time. It will only be half a year at most. As for this hot air balloon, the technology is not yet mature. When I've studied it, I'll be a set of messengers to send it to you!"

Li Siwen was immediately happy and smiled foolishly: "That's great, I want to fly in my dreams."

Li Mu shook his head helplessly. He didn't know how to evaluate the obsession of Tang people in pursuit of "flying to the sky". Maybe this is the primitive desire of mankind. If there were no such primitive desire, the airplane would not have been born in more than a year.

Li Mu took his younger brothers toasted a circle of wine, then returned to the yard and entered Bai Qiaoqiao's room. Li Zhien was also here. When he saw Li Mu's face turned red, like a ripe apple, and he didn't dare to look at his eyes. Last night, both of them took off half of their clothes and hit the hot air balloon on the tree. When they remembered, they felt embarrassed and had a fever on their cheeks.

Li Mu could understand that he hadn't seen Wang Ou. He saw Wang Gui while toasting just now. Wang Ou was not here, probably because he was afraid that he would be seen.

Li Siwen's wife Qin Yu was talking to Bai Qiaoqiao. Li Mu saw a golden lock next to the pillow and knew that it must be Qin Yu's intention. It seemed that this brother and sister had chosen the right choice, with a handsome appearance, a prominent family background, and it was even more difficult to be delicate and understand human feelings. For Li Siwen, it was an excellent complement to her. Moreover, she still had a lot of skills.

After chatting for a while, Li Mu brought Li Siwen out again. When he was toasting, he didn't see Li Ji and Qin Qiong. After asking the students who helped, he realized that the two learned that there were rhinos in the valley and went to see the rhinos together.

Li Mu brought Li Siwen to come over. When Li Ji saw Li Mu, he asked about what happened last night. Li Mu told him about the cause and effect. While Li Ji breathed a sigh of relief, he was still frowning.

There are no outsiders here, and Li Ji doesn't need to be cautious and said worriedly: "Li Mu, you are still too careless. When I returned to Chang'an, I felt uneasy when I heard about some of the things you did. This is also my fault. I, the adoptive father, are not in Chang'an, and I cannot persuade you in time. I have wanted to explain to you in detail these days, but because of Siwen's marriage, I have been delayed. Now I have time, so I have to talk to you."

Li Mu was asking to tell Li Ji about something, so he led everyone to the "Dongpo Pavilion" on the east hillside. This was a bad thing he had when he was choosing a site and ordered Gongsun Kang to build a pavilion. It was just a joke at the time, but Gongsun Kang never carried out his words without any discount. The "Dongpo Pavilion" on the east hillside was built with the courtyard.

The four of them sat down in the pavilion, and Li Ji opened his mouth: "Li Mu, let's talk about it one by one. The first mistake you did during this period was to have something to do with the Prince of Hejian. I have told you about the Prince of Hejian. This is a person who cannot be touched, because he is the only person who makes His Majesty and the Emperor feel guilty in his heart."

In this case, Li Ji would not say it in front of Qin Qiong the day before yesterday. But after yesterday, the two of them had formed a family. This was an unbreakable alliance, and they were already grasshoppers on a rope, so they had no scruples.

"...You must know that if you fight the mien, you will be able to raise the mien hatred. If the emperor can afford the merits of his ministers, he will naturally not have to worry about anything. But the merits of the Hejian prince cannot afford them. Throughout history, those who have made great contributions have not ended well. You must know this in your heart."
