Li Xiang nodded yes. In fact, the principle www.biquge.info of hot air balloon is very simple, but it is the same as the "Pseudo-Shangshu", the people have been in awe of the sky for thousands of years, and our country has invented the Kongming pink lamp in ancient times, but who would have thought of creating a larger object to carry people into the sky? Now there is no rubber, Li Xiang has to use cowhide instead, compared to hydrogen balloons, the heat is quite safe. Even if the supply of hot air stops due to unexpected factors, due to the buoyancy of the balloon and the resistance of the air, the balloon will fall at a very slow speed and will not cause life damage to people. The main thing is that there can be no such huge cowhide, and it takes a lot of cowhide inlays to create this balloon, and it must be firm when sewn, otherwise it is no joke that the balloon will burst when the hot gas expands. In fact, for the first time in history, a balloon was lifted off to meet this situation. Therefore, Li Xiang was not sloppy when making this balloon and personally supervised it.

The little princess raised her neck and said, "Lord Li, can this thing really make people fly into the sky?" ”

She had been looking forward to this balloon for a long time. I've been looking forward to it for more than half a year.

Zhao Ji replied for Li Xiang on the side: "Yes, because the air is heated, the density is light, and there is wind, so it can carry people to the sky." ”

He followed Li Xiang to study physics for more than half a year, and he had long understood this simple truth, but Li Xiang still didn't dare to teach chemistry, Li Xiang was afraid, this was simply a complete subversion of all the people's understanding of nature and Confucianism for thousands of years. With him as a teenager, he didn't dare to face the attacks of all living beings in the world.

The little princess said again: "Lord Li, you are really a heavenly immortal who came down to help my father?" ”

Li Xiang sweated on his head, there are such rumors among the people, but he can't say this to the emperor, this little princess heard it from somewhere, and she actually said it directly in front of such a minister and the emperor and queen.

He said, "Your Royal Highness, you must not say this. Wechen just read a little more. If it is really a heavenly immortal who descended to earth and was reincarnated, it is just a small god, and His Majesty is a big god, who is in charge of the small gods. ”

Emperor Lizong smiled, this kid is clever.

Li Xiang connected the pipe and lit the coal stove. After a while, the air in the balloon was heated and began to sway with the wind, turning into an upward trend, and the rope was also stretched tightly. Li Xiang knew that the time was almost up. But he was in trouble and asked Emperor Lizong, "Who should go first?" ”

According to reason, Emperor Lizong should go first, after all, he is the Son of Heaven, and it can be said that it can be big or small. But if someone picks up something and makes a fuss, Li Xiang will also be unbearable. Emperor Danlizong was the first to go up, and someone would also take it out to make a fuss.

It's like Kou Zhun. In the first year of Jingde, Liao Shengzong personally marched south to attack the Song Dynasty. Emperor Song was afraid of the enemy, obeyed the plans of Li Boyu, Chen Yaosu and other ministers, and wanted to move the capital to Jinling and flee south. Tongping Zhangshi Kou Zhun tried his best to disagree with the public and persuaded the Song Emperor to supervise the battle in Lanzhou, but as a result, his morale was greatly boosted and he made the "Alliance of Lanyuan". In the third year of Jingde, Li Boyu provoked Emperor Song: "Your Majesty is not ashamed of the battle of Lanyuan, but it is said that there is a social merit, why not?" …… The alliance under the city, "Spring and Autumn" is ashamed. The move of the abyss is the alliance under the city. With the value of ten thousand times and the alliance under the city, what a shame! Later, Kou Zhun dismissed the prime minister.

Li Boyu, the crown prince, once advised Li Xiang: "Gewu arithmetic is a science, but after all, it is the knowledge of craftsmen. ”

Li Xiang also agreed with him, it is impossible to ask Zhao Ji to study physical chemistry in the future, he still has to learn the art of the emperor as a tight, he must not become the carpenter emperor of the Ming Dynasty, not to govern the country, but to take an ax and saw to make furniture all day long, the Ming Dynasty is a mess, and then hand over a tattered country to his younger brother, and finally Zhenzhen wants to govern but can not govern, first civil strife, and then the Qing people entered the customs and lost the country.

At this time, Zhao Ji helped Li Xiang speak: "Li Taibao, Master Li also often teaches Gu to learn the way to govern the world. It's just that he doesn't make a big sense. ”

Li Boyu also heard that on the first day that Li Xiang entered the palace, the smart crown prince gave Li Xiang a few difficult things, and smiled silently.

After Li Boyu went out, Zhao Ji quietly asked Li Xiang: "I often hear people say that villains and gentlemen, is this Li a villain, or a traitor?" ”

Li Xiang almost wanted to cover his mouth, he was silent for a while and said, "I don't completely deny Lord Li, he also contributed to the prosperity of the Song Dynasty. ”

When it comes to Li Boyu, no one will say good things about him. The reason why Emperor Lizong did those ridiculous things in his later years, such as Feng Chan Xiangrui, was all done by this Li Boyu

Zhao Ji thought for a while and said, "Master Li, Lone understands, a gentleman has a gentleman's practice, and a villain has a villain's usage." For example, when you wrote the book "Three Kingdoms", you asked Zhou Yu for foreign affairs and Zhang Zhao for internal affairs. ”

Li Xiang was overjoyed, and he said with a smile: "Your Highness is wise." ”

Zhao Ji also felt the joy on his face from the bottom of his heart, and said warmly: "Li Xiang, you made a blood oath that day to help our Great Song Dynasty build a strong country." In the future, you will have to help Gu. ”

and held Li Xiang's hand tightly. The two teenagers looked at each other and smiled again, and this heartfelt smile made the two feel warm again.

Li Xiang asked this question sharply enough, and these ministers looked at each other, but none of them dared to speak.

At this time, Yan Guifei asked, "Lord Li, is there any danger for people up there?" ”

Li Xiang replied: "The minister who did it did not dare to say, but the minister made this guarantee that there is no danger, but it must be repaired again after a long time, because these twine will corrode because of time, and there will be danger at that time." ”

Emperor Lizong heard that there was no danger, and his heart was moved, heaven, who doesn't want to. So he said, "Then I'll be the first to board this hot air balloon." ”

Li Xiang said: "Your Majesty can board this balloon, and only Your Majesty is qualified to be the first to board the balloon, and Weichen will also accompany Your Majesty and perform a show for Your Majesty." It's a very fun show. But His Majesty will not allow anyone else to make a fuss about this in the future. ”

Emperor Lizong smiled and said, "I can guarantee it." But what other fun shows do you have? ”

Li Xiang smiled slightly, and he said mysteriously: "Your Majesty will know when the time comes, but Your Majesty can rest assured that it will be safe for Weichen to perform this show." ”

"Oh?" Emperor Lizong's heart itched even more when he heard this. He knew that no matter what Li Xiang did, it was magical.

The little princess is also going to be noisy. So the first candidates for the balloon were Emperor Lizong, the little princess, Li Xiang and a soldier. Of course, the first person to board the base under the balloon was Emperor Lizong, and no one dared to grab it. Li Xiang also asked them to wear more clothes, after all, it was colder than the ground at high altitude, and Emperor Lizong was not in good health, so he had a cold or something, or he would die because of this cold, and he still couldn't escape the blame.
