Because Du He had no experience in leading troops, the second Li Chengqian sent Su Dingfang to Longshouyuan to assist in training the Flying Eagle Army, and Du He and Zhao Jie also began to make hot air balloons according to the drawings.

The DPRK and China temporarily calmed down because of Li Chengqian's meal of sticks and dozens of dishes.

Early that morning, Du He came to the palace to see Li Chengqian, saying that the hot air balloon had been made and assembled.

So Li Chengqian quietly took the East Palace guards and went out of the palace to Longshou Yuan to watch the first flight of the hot air balloon.

Li Chengqian and his entourage rode their war horses to Longshou Plain, and saw that the area along the river had been blocked by Duhe, and when they walked in, they saw a row of dozens of large baskets along the river embankment, and next to the baskets stood several strong men with big shoulders and round waists, waiting to listen to Li Chengqian's command.

Li Chengqian sighed in his heart, in the end, he has traveled to Datang to do things is atmospheric, and he can make so many things out of an experiment.

The people inside saw Li Chengqian riding a horse and walked in, and Su Dingfang hurriedly led people forward to greet him.

The group came to the basket and dismounted, the soldiers took everyone's war horses away, Su Dingfang walked in front of Li Chengqian and saluted solemnly again: "The minister heard the captain of the horse say that these are artifacts that can fly to the sky?"

As he spoke, he looked at the baskets and the oil-soaked silk bags in the baskets, obviously not believing that these things could go to heaven.

Li Chengqian was looking at the basket in front of him happily and didn't notice Su Dingfang's expression, and when he heard this, he just waved his hand casually and said, "I can still deceive you, quickly order someone to light a fire and let one fly for General Su to see." ”

"Yes!" Du He hurriedly bowed down to receive the order, and went to the side to direct people to light and release hot air balloons.

The principle of hot air balloon is simple, the workmanship is also simple, if the requirements are not high, the materials can be used, and the book records that some people used firewood as fuel to fly the hot air balloon at the earliest.

Of course, Li Chengqian didn't need to use firewood, because the Tang Dynasty already had fire oil.

When Du He first made the first one, he quietly did the experiment, and then he dared to invite Li Chengqian to come and see, and now he is familiar with it again in front of everyone, whether it is him or the operator.

Li Chengqian saw that with the burning of the oil and soon the airbag on the hot air balloon puffed up, and as soon as the airbag puffed up, it swayed and rose with the wind and river.

Li Chengqian couldn't help but look at Du He when he saw the empty basket and said, "Why don't you put something in it?"

Du He was excited about the hot air balloon taking off, and was stunned by Li Chengqian's question: "What to put it?"

At the time of this question and answer, the hot air balloon had already flown two or three meters high, and Li Chengqian saw that there was not only nothing in the basket, but also a rope underneath.

Seeing the hot air balloon flying higher and higher, he couldn't help but be furious, pointed at Du He with a horsewhip and scolded: "Idiot! ”

Li Chengqian, who was looking up at the hot air balloon in the sky, was shocked by anger and looked back at Li Chengqian in amazement.

Du He, who was scolded, didn't know what he was wrong with, he had always thought highly of himself and had never been insulted like this, and he bowed his hand to Li Chengqian with a red face and said: "Please make it clear to His Royal Highness the Prince, what is wrong with the minister?"

Seeing this, Li Chengqian also knew that he had lost his words, but since he had already said it, he naturally confessed his mistake, and when he saw this, he snorted angrily and asked: "I asked you to make this flying artifact in order to send soldiers into the sky, so that soldiers can easily fly over dangerous places and throw gunpowder packets on the ground." If you put an empty basket in the sky, it can be regarded as a large Kong Ming lantern at most, and I have nothing to do when I am idle, so I can see you put the Kong Ming lantern?"

Hearing this, Su Dingfang hurriedly looked up at the hot air balloon in the sky, watched the hot air balloon fly farther and farther away, and muttered in his mouth: "Kong Ming lantern ......"

Li Chengqian said angrily when he heard this: "If the night is very bright." ”

Su Dingfang nodded innocently when he heard this: "His Royal Highness the Crown Prince is clever!" ”

After saying that, he immediately realized that Du He hurriedly turned his head to look, only to see that Du He also looked up at the hot air balloon in the sky, and looked at Li Chengqian's expression and said: "It's the minister's fault!" ”

Li Chengqian also raised his head and the hot air balloon flew to cause a fire, so he ordered: "Send a few people to follow the hot air balloon, the oil in it will fall by itself after it burns, be careful not to cause a fire!" ”

"Obey the order!" Su Dingfang hurriedly went to send someone.

Only then did Li Chengqian walk to Du He's side and help him up, and said: "You have to remember that the Flying Eagle will build this hot air balloon in the future, and you must study how to use this hot air, so that you can command the Flying Eagle Army to overcome difficulties." ”

"Thank you for the teachings of His Royal Highness the Crown Prince!" Du He said sincerely.

Li Chengqian nodded and said, "Go find a long rope and two, and then experiment again." ”

At that moment, Du He didn't ask Li Chengqian what he was looking for these things, and as soon as he heard the order, he immediately went to find them himself.

The hot air balloon experiment was a success, and on the same day, Li Chengqian explained some things about the Flying Eagle Flying Army, and then returned to the Taiji Palace before noon.

Lunch was eaten with Li Shimin, and when he was eating, he mentioned to Li Shimin that tomorrow, June 19, was originally the day of the Great Dynasty, and now Li Chengqian is in charge of the country, so he is preparing to ascend to the court in the Jiade Hall of the East Palace.

Li Shimin did not have any opinion on this, and Li Chengqian went out and ordered someone to pass on the decree that the Jiade Hall would ascend to the court tomorrow.

After learning of this, the outside officials were also happy and sad, and the main reason for the more sorrow was that several prime ministers and monks had already stored hundreds of letters of advice, and these notes were all scolding Li Chengqian for being cruel and unkind.

Gao Shilian and Yang Shidao originally thought that if they handed over these sparse music now, Li Chengqian's temper would inevitably conflict with these sparse people, so they both pressed Zhongshu and prepared to wait for Li Shimin's illness to recover and hand it over to him directly.

But tomorrow Li Chengqian will be promoted in the Jiade Hall of the East Palace and accept the worship of hundreds of officials, those imperial histories should not scold Li Chengqian in person, think about that picture, I really don't know what will happen tomorrow?

Of course, those who are happy are those who want to scold Li Chengqian in person, these people have been dissatisfied with Li Chengqian since Li Chengqian was in charge of the country, they were stopped outside the Liangyi Gate, and the music on the top was like a stone sinking into the sea, this time I finally had the opportunity to meet, even if I fought to the death, I scolded you in person, a tyrant.

On the morning of the second day, the palace maids in the Ganlu Hall were busy, and the ceremonies of the crown prince in the early Tang Dynasty were all modeled after the emperor's dynasty in the Taiji Palace.

At this critical time, Li Chengqian did not dare to slack off in the palace, the central province and the East Palace, and they were cautious one by one, for fear that something would go wrong and be caught.

The subordinates were all busy, and Li Chengqian, the protagonist, naturally couldn't be idle, so he was called by Shang Gong to change his clothes early.

After tossing for half an hour, Li Chengqian dressed neatly, got into the car, and drove out from Chengtianmen to the East Palace Jiade Hall.

Li Chengqian sat in the car and saw from a distance by the light that there was already a long queue of ministers in front of the Jiafu Gate of the East Palace.

When Li Chengqian's car drove to the Jiafu Gate, the East Palace Guards opened the Jiafu Gate, and Li Chengqian's car and the ministers behind them walked into the East Palace Jiade Hall in a mighty manner.

Li Chengqian entered the throne of the Jiade Palace, ordered Liu Kui to put the evidence of the crimes of the Chang'an clan collected by Qiu Shenji on the table, and looked at the courtiers who were marching into the main hall in a cold manner.
