It was already noon when Li Mu came out of the palace. Li Shimin's enthusiasm for hot air balloons was extraordinary, so he had to let Li Mu explain the principles to him. Li Mu had no choice but to explain, starting with the Kongming Lantern, and then thermal expansion and contraction.
, and then to the basic structure, materials, etc. of a hot air balloon, my mouth is dry.
Li Shimin is a good student. He listens carefully and is very humble when asking for advice. He is just a bit stupid. But this is not his fault. Although Li Mu has tried very hard to explain some physics principles in an easy-to-understand manner.
I understand, but after all, Li Shimin has no foundation in physics and has no imagination in his mind to match it, so his understanding is naturally slower.
Fortunately, hot air balloons are not complicated in the first place. Li Mu even made gestures and explanations, which can be regarded as popular science for Li Shimin.
After leaving the palace, Li Mu did not rush back, but went straight to the British Palace. Yesterday he failed to get the hot air balloon, did not fly over the British Palace, and did not see the scene of Li Siwen getting married. As his eldest brother, Li Mu was worried
I feel a bit sorry. Naturally, I have to go to my house today and have a glass of wedding wine.
But what he didn't expect was that when Li Mu arrived at the British Duke's Mansion, he came to nothing. The concierge told him that the family got up early and rushed to the valley outside the city.
This incident made Li Mu have no choice but to rush out of the city. After catching up with the sun, he finally saw the gate of his small courtyard.
On both sides of the road in front of the door, the carriages could no longer stop. They were all crowded with people. Li Mu could see from a distance that the running water mats had been set up again. It was obvious that officials who had gone to Li Siwen's place yesterday and had not come in person came to deliver gifts.
Already.
Li Siwen was waiting for his guests. When he saw Li Mu coming back, he threw the wine bottle in his hand and ran over, shouting as he ran: "Brother, have you come down from the sky? How did you get up? Take me to fly around too."
ah!"
Dugujiu followed closely behind, his eyes blazing. Although he didn't say anything, his meaning was already very obvious.
Li Mu got off the horse and said, "Isn't it just flying? It's a piece of cake. Someday when I have free time, I will make a hot air balloon and take you all flying around."
"Don't change the date!" Li Siwen said anxiously: "Let's fly after we have eaten. Where is the carriage? Why didn't you bring it back?"
"Burn!" Li Mu walked into the courtyard. As he walked, he told several people what happened to "Hot Air Balloon No. 1". Li Siwen suddenly felt regretful and murmured: "I will return to Dingxiang the day after tomorrow.
, it seems that it can’t fly.”
Li Mu stopped and frowned: "Leaving the next day? So urgent? Your Majesty asked you to leave? I'll go tell him, that's too unkind!"
Li Siwen shook his head and said, "Brother, it's not His Majesty's will. It's me who wants to leave."
"It has been a month since I left Dingxiang. Every plant and tree in that city was built by me and my people. Although there are no strong enemies nearby and there is no need to worry about anything happening, I still worry about it in my heart yesterday.
After discussing with my father-in-law, Xiaoyu will go with me. I will accompany her back home tomorrow to buy some more things, and leave the day after tomorrow."
Li Siwen smiled, his face less playful and more sad, his eyes slightly red: "Brother, I'm leaving this time. The next time we meet again, it will be a year later."
"It won't be that long." Li Mu waved his hand and said, "After my spring vacation, I will go to Zhangjiaji to pick up your sister-in-law. I will definitely pass by Dingxiang then. It will only take half a year at most. As for this hot air balloon, now
The technology is not mature yet. When I finish researching it, I will make a set and send it to you!"
Li Siwen suddenly became happy and said with a silly smile: "That's great, I want to fly in my dreams."
Li Mu shook his head helplessly. He didn't know how to evaluate the Tang people's obsession with "flying to the sky". Maybe this is the primitive desire of human beings. Without this primitive desire, it would be impossible to survive a year or more later.
There will be no such thing as an airplane.
Li Mu took his brothers and toasted a round of wine, and then returned to the small courtyard and entered Bai Qiaoqiao's room. Li Zhien was also here. When he saw Li Mu, his face immediately turned red, like a ripe bird.
They were like apples and didn't dare to look into his eyes. Last night, both of them took off half of their clothes, and the hot air balloon hit a tree. Thinking about it, their cheeks burned with embarrassment.
Li Mu could understand that he didn't see Wang Ou. He saw Wang when he was toasting just now. Wang Ou was not there, probably because he was afraid of being 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 heart. He couldn't help but be very happy. It seemed that he had chosen the right sibling. He was handsome and had a prominent family background, which was even more rare.
She has a delicate mind and understands human feelings. She is an excellent complement to Li Siwen. What's more, she also has a lot of kung fu skills.
After chatting for a while, Li Mu brought Li Siwen out again. When they were toasting, Li Ji and Qin Qiong were not seen. After asking the students who helped, they found out that they had learned that there were rhinos in the valley and went to see the rhinos together.
Li Mu came over with Li Siwen. When Li Ji saw Li Mu, he asked about what happened last night. Li Mu told the cause and effect. While Li Ji let out a sigh of relief, he still frowned.
There were no outsiders here, and Li Ji didn't need to be cautious. He said worriedly: "Li Mu, you are still too careless. When I returned to Chang'an and heard about some of the things you did, I felt uneasy. This is also my fault.
As a foster father, I am not in Chang'an, so I cannot advise you on many things in time. I have wanted to tell you in detail in the past few days, but due to the matter of Siwen's marriage, I have been delayed. Now that I have time, I have to talk to you carefully.
"
Li Mu also wanted to tell Li Ji something, so he led everyone to the "Dongpo Pavilion" on the east hillside. This was the pavilion he ordered Gongsun Kang to build on a whim when he was choosing a site. At that time,
It was just a joke, but Gongsun Kang always carried out his words without compromise. The "Dongpo Pavilion" on the east hillside was built together with the small courtyard.
The four of them sat down in the pavilion, and Li Ji started talking: "Li Mu, let's talk about one thing at a time. The first wrong thing you did during this period was to get involved with the King of Hejian County.
.I have told you about the Prince of Hejian County. This is a person who cannot be touched, because he is the only one who makes both Your Majesty and the Supreme Emperor feel guilty."
In this case, Li Ji would not have said it in front of Qin Qiong the day before yesterday. But after yesterday, the two of them have become in-laws. This is an unbreakable covenant, and it is already a grasshopper on a rope, so
No worries.
"... You must know that the emperor can afford to reward the merits of the ministers. But the achievements of the princes of Hejian cannot be rewarded. Throughout the ages, the achievements have been unparalleled.
There will be no good end for the master, you must know this in your heart."
Qin Qiong nodded slightly, obviously agreeing with Li Ji's words. Li Siwen looked confused. He didn't understand this kind of topic at all.
