Seventeen years, the eighteenth day of the first month, King Teng Yuanying fainted, the emperor came, the four concubines of the harem, the princesses of the kings and the officials above the third grade accompanied, the envoys of various countries set up a wine banquet in Chang'an along the way, all kinds of beauties sang and danced to congratulate each other, and Changle Weiyang...... Shangguan Yi slowly put down the pen in his hand, and saw Li Yuanying withdraw the short sword in his hand, away from his fragile neck; Princess Jinyang put away the bricks in her hand and sat back beside the emperor obediently...... didn't dare to raise his sleeve to wipe the beads of sweat on his forehead, bowed and bowed and exited the west side hall.

As soon as he walked out of the Lizheng Palace, he sat on the ground with a soft foot, Shangguan Yi breathed a long sigh of relief, and finally raised his sleeve and wiped his forehead: After writing six versions...... Finally passed.

Li Zhi, the king of Jin, put down the tea cup in his hand, and after hesitating for three breaths, he said in a low voice: "Aya, you are all mouthful, I'm afraid it's ...... I'm afraid I can't prevent ......."

"Brother, what is important to the princes? It's just a matter of winning the name before and after death." Princess Jinyang said softly while smashing the walnut with a small hammer. "As long as there is no relevant record in the official historical materials, the biographies of wild history are all the words of one family, which is not enough to be believed by future generations. That's all because of the donkey of Qian, the elk of Linjiang and the teacher's sayings written by Uncle, and the crab song, which shaved the face of the scholars and doctors, and the slanderous words they framed."

As for the word of mouth of the people of Chang'an, it is easy to solve, as long as there are more novel and interesting things, it will not take three days for them to forget what happened on the day of Uncle's wedding. Uncle said that public opinion can be guided and manipulated, because most of them don't care about what the truth of the matter is, they just like to watch the excitement and add some fresh talk to the ordinary life.

"You're not trying to test that...... It's going to be a huge ball, right?" Li Zhi thought of the strange leather ball that Princess Jinyang and her master Gongsun Bai were making in the Furong Garden, his eyes widened wider and wider, his hands supported the desk, he leaned forward, and said in a solemn and cold voice. "You must not follow Mr. Gongsun on that ball, it's too dangerous!"

Gongsun Bai's swordsmanship is at its peak, so naturally there will be no danger, but Jinyang can't, she is just a little girl who has not yet reached the end of her life, and her body has not grown up, and there are many swordsmanship tricks that cannot be practiced at all. If Gongsun Bai was inadvertently negligent...... It was in the air, and Jin Yang was not Ye Fashan's birdman, and the consequences were unimaginable!

"Huge balls?" Li Shimin and Li Yuanying looked at Jinyang Xiaobaozi at the same time and asked suspiciously.

Could it be a hot air balloon...... Li Yuanying thought of a certain picture in the picture book story he gave to Jinyang Xiaobao, and felt that the green tendons on his forehead were on the verge of going berserk: The little son is not sensible, and the old ghost of Gongsun Bai is not sensible? It's not that hot air balloons can't be made, but they shouldn't let Jinyang Xiaobaozi know when they are not yet ripe.

Princess Jinyang puffed out her cheeks aggrievedly, took out the picture scroll from her sleeve, and unfolded it for Li Shimin to see.

「？？？」 Li Shimin looked at the ...... flying in mid-air on the scroll The ball came to say solemnly. "You are not allowed to ride on it."

After a pause, he added, "Except for Mr. Gongsun, there are a few of them...... Unless it is safe after many tests, no one else is allowed to ride on it."

Datang is now short of people, not only in each department, but also in all walks of life.

"Brother, you can use prisoners or death row prisoners for experiments." Li Yuanying looked at the scroll more carefully and found a structure similar to that that could regulate the flame. Although Li Chunfeng signed countless bills, he did not gain nothing, and the failed experiment provided Gongsun Bai and Wei Guizang with a lot of first-hand information, very precious first-hand information. "No." Li Shimin resolutely refused, without any hesitation or hesitation, "Captives must be used to build roads, and they cannot be wasted at will, and death row prisoners must be dealt with according to the law.

Shangguan Yi was able to be said to change the records related to the wedding, to put it bluntly, just because he knew that if it was realistic, the people who secretly beat him with a sack could not be counted on the two hands of him and his daughter-in-law combined. In short, in a nutshell, it's nothing more than four words, and it's hard to be angry.

"Then use a dog, or a sheep." Li Yuanying secretly pursed the corners of his mouth, Li Erfeng is now more and more cowardly, and he no longer has the bravery of the horizontal knife back then. "No matter how lively and lively the conversation is, it can't compare to the desire to fly in the sky

, but I must wait until I leave Chang'an before trying."

The first recorded flight of a hot air balloon took place on June 4, 1783, when the brothers of Montgolfier in the Gallic chicken land gave a public performance on Place d'Annone, made of pasted paper, the seams of which were fastened with buttons. The brothers used straw and wood to batch the passengers in the balloon, a rooster, a goat and a duck.

On September 19 of the same year, in front of the Palace of Versailles, the Montgolfier brothers staged a hot air balloon launch for the king, queen, court ministers and 130,000 citizens of Huadu. On the afternoon of November 21, they made the world's first manned air flight at Fort Muette, where the hot air balloon flew for 25 minutes and landed near Chef Wolf Square after flying half of Huadu, a full 120 years before the Wright brothers' plane flew.

I haven't mentioned the hot air balloon, originally thinking that Li Chunfeng could get out of the helicopter first, but I didn't expect to give him a chance and he didn't use it, and then he had to confirm whether the lower Kong Ming lantern already existed, and I didn't expect that there really was no Kong Ming lantern in the land of Sichuan and Shu. After three years of exploring the New World, alas, the pace of scientific research has slowed down a lot.

"After three days, go to Yangzhou, do things well, and don't make trouble for me again." Li Shimin thought of the hustle and bustle on the night of the wedding, raised his hand and rubbed his forehead, blaming the envoys for preparing a lot of wine...... However, the taste of that wine is really good, so that Mr. Gongsun can study and improve it, and then sell it to them backhandedly, how can Qian Mou calculate the money with a small amount of money in his heart? It's all because the vertical is hateful, and he has led a certain person astray!

"Why?" Li Yuanying bowed without much sincerity, looked at the aggrieved little bun, and explained softly. "The materials you use to make the ball have a certain flammability, and looking at your picture scroll, there is an open flame exposed, and it is too dangerous to fly manned. There are more important and unknown things, we don't know how high it will fly, and we don't know if there will be other dangers at high altitudes, that is, Mr. Gongsun, and I don't recommend him to take the test for the first time."

He couldn't tell Jinyang Xiaobaozi that the temperature at high altitude was very low, and he couldn't say that there was very little oxygen, and some test processes couldn't be omitted.

"Only." Princess Jinyang responded obediently.

Li Shimin: "......"
