Take the mall to Datang

Dugu Ruolan saw that she was getting farther and farther away from the ground, her body was getting smaller and smaller, her heart was pounding faster, and her hands were gripping tighter. At this moment, she didn't feel anything, she was completely in a state of bewilderment.

The sky, the ground, the strong wind, and the huge umbrella wings stretched out for a distance of more than ten meters. The flying state was very stable, which made her feel at ease. Could it be indulgence, and she shouted heartily in the sky.

Yuan Shan controls the glider, thinking that the actual operation is not that difficult, soaring in the open sky, looking sideways, you can have a panoramic view of the whole Chang'an.

In the imperial palace, Ma He just went out, and immediately ran in yelling as soon as he raised his head.

Li Shimin frowned, when did he see Ma He so flustered, could it be that there was a mutiny, Gao's atmosphere became tense.

"Your Majesty... Duke Lan... is flying in the sky..." Ma He said nervously.

Li Shimin stood up suddenly and scolded: "What did you say?"

"Your Majesty, Duke Lan and her wife are flying in the sky..." Ma He repeated, this time bringing up Dugu Ruolan.

Li Shimin couldn't sit still anymore, people are born to fly, so he rushed out without saying a few steps, looking up, Yuan Shan was sitting inside a strange thing, really flying.

Tang Jian went out to take a look, and said involuntarily, "It's really flying."

But they are much more sensible, especially Li Shimin's eyes are microscopic, and he immediately seems to know what the strange thing Yuan Shan is playing with.

Yuan Shan didn't expect to see Li Shimin like this, and he was still waving from above, and asked Dugu Ruolan to wave.

Li Shimin smiled pretending to be calm, and also waved his hand, looking calm, but his heart was trembling so violently that he couldn't slow down at all.

The sound of "Boom~" passed the palace and flew directly to a higher place.

The soldiers in the palace were all shocked, and a group of people surrounded them, staring at the tall things helplessly.

In the East Palace, as soon as Li Chengqian sat down, he was startled by people's exclamations. Hearing that Yuan Shan was born to fly, he couldn't sit still. .

More and more people saw Yuanshan flying in the sky, and seeing all the people in Chang'an come out to watch, Yuanshan felt a sense of accomplishment, but this time he did not lower the flight, and flew in the air for a long time, from Chang'an to Yuan's house The manor can be seen clearly.

Worried about insufficient fuel, the first flight ended like this. According to the performance of this hang glider, it can fly for at least five hours.

Return to the Xishan clearing and land safely.

When Dugu Ruolan came down, her legs were a little numb, and Yuan Shan supported her.

"It's really flying, and my husband Qianyu will also fly in the sky." Du Qianyu said in a delicate voice.

Yuwen Linglong was eager to try, but was held back by Yuwen Wanrou. After all, she was the second wife, so she couldn't be rude.

"Okay, don't worry, everyone in our Duke's Mansion has a share, but today's first test flight is here, and we will continue tomorrow, haha..." Yuan Shan was very happy.

Chapter 874

Before Yuan Shan returned home, a group of people were discussing on the street.

Afterwards, there was even a team of Jinwu Guards who directly invited Yuan Shan to the palace.

Li Chengqian rushed directly to the space, and asked again, Yuan Shan had entered the palace, and His Royal Highness, who was sadly urged, wanted to turn back, but he didn't do that after thinking about it, but continued to wait at the Duke Lan's mansion.

In the palace, in the imperial study, Li Shimin was sitting upright, with a sullen face, not knowing what to write, Yuan Shan looked around and smiled at Tang Jian.

Tang Jian hadn't reacted from the surprise at this time, and his eyes were wrong when he looked at Yuan Shan.

Yuan Shan was stared at by him and screamed, thinking that Tang Jian, Minister of the Ministry of Civil Affairs, could not be that one, even if it was so obvious, it was unimaginable.

"Yuanshan, I came here to ask about the population of Donghai Prefecture, but I didn't expect you to go to heaven. Let me talk about this first. The people in Chang'an City are talking about you, saying that you have ascended to immortality." " Li Shimin said in a cold tone.

In fact, more than anyone else, he wanted to know what was going on.

"The matter of 'Flying' is not complicated. In fact, it is a kind of flying equipment that I researched. It is roughly the same thing as a steam cart or a locomotive. There is no such thing as a mysterious thing. It’s not easy, it requires systematic training and courage, and the accident rate is high.” Yuan Shan explained.

Li Shimin had long guessed that it was a kind of machine, and when Yuan Shan confirmed it himself, his complexion improved a lot.

"Glider, that's a good name. Since you can fly to the sky, doesn't it mean that everyone in Datang can go to the sky?" Li Shimin asked.

Yuan Shan thought for a while and felt that there was nothing wrong with this, and immediately said: "Theoretically, this is the case, but the cost of flying is too high, the maintenance fee of equipment, fuel fee, labor fee for the driver, risk guarantee fee, and no liability agreement Waiting for the calculation, it is at least about [-] guan per flight."

Li Shimin knew that he was talking nonsense, how much is Wanguan, and is a piece of equipment that expensive?

"You are indeed a shrewd person. Gliders are of great significance to Datang. If the Ministry of War has mastered this technology, wouldn't it be very effective in combat? Therefore, if I want this equipment, you can make a price." Li Shimin said.

Yuan Shan didn't hesitate, what a joke, you can't make a single internal combustion engine, isn't it just a decoration for you, after thinking about it, he said: "Your Majesty, the glider still has many disadvantages, it is still in the research and development stage, and the technology is not yet mature. , if the imperial court forces the research, I am afraid it will really waste people and waste money."

"Are you questioning the strength of the Military Weapons Supervisor?" Li Shimin said.

"Of course I don't dare, it's just that the accident rate of glider is really high. It can be said that there is no other person in Tang Dynasty who can master this flying technology except for the minister, and there is only one glider. If it is really scrapped, the minister will not be able to manufacture the first For the second one, the complexity of the workmanship is comparable to that of Zulue machinery such as trains." Yuan Shan told the truth, and it is true.

Besides, do they know what airflow and other phenomena are? Turbulence in the air is very dangerous.

Li Shimin didn't give in, his expression immediately turned cold. It seemed that a good high-end entertainment project was about to be killed, and no one from the Yuan family had sat in it yet.

"Your Majesty, it's not about money. It's very dangerous to operate a machine in the air. If Your Majesty really wants to make people fly into the sky, there are actually many ways, but everything has its drawbacks." Yuan Shan continued.

When Li Shimin heard that there was still a way to make people fly into the sky, his eyes lit up immediately. He could see that Yuan Shan really didn't intend to give up the glider. The emperor can't afford to lose this man.

"Let's hear about the method." Li Shimin said.

"I know that there is a way, which is a concept that was needed in ancient times. It is to enlarge the Kongming lantern several times, sew the balloon with leather, and inflate the hot air balloon with charcoal fire to support combustion, so that people can fly in this hot air balloon. The disadvantage is to fly up. It’s easy, but the control of the direction is more complicated. It needs to change the direction according to different heights. It is greatly affected by environmental factors, and the risk factor of landing is very high. If you want to climb high and look far, it is a method to use ropes.” Yuan Shan said.

"Heat a leather balloon with charcoal fire and lift it into the air? What you said is amazing, but I don't know if it is really feasible." Li Shimin said.

"Of course it's possible, but everything has risks. In short, it's easier to go up than it is to come down." Yuan Shan said.

Li Shimin pondered for a while and said, "What else can I do?"

Yuan Shan was secretly greedy, and continued to say with a smile on his face: "There is a kind of parachute, which can let people slide down from the hillside smoothly. If you control it properly, you can use the parachute to glide in the air for a certain distance."

Li Shimin pondered in his heart how it sounds so weird to be able to fly down to the ground after jumping down from the mountain. He immediately thought about the scene of a group of people falling from the top of the mountain, but he couldn't figure out how people could fly down.

"It's better for you to make something and show it to me." Li Shimin said.

Yuan Shan was dumbfounded for a while, it's fine if you don't believe it, I don't want to jump off the cliff.

Yuan Shan expressed a very embarrassed look and said: "These things are expensive to manufacture and require extremely high technology. They cannot be produced in a short while."

"You can ask the military supervisor to help, and the material craftsmen can be dispatched as you like." Li Shimin said straightforwardly.

Yuan Shan secretly cursed that he was really old and cunning, saving money is not like that, and said with a smile: "In that case, I know."

"Okay, now let's talk about the population of Donghai Prefecture. I heard that you were blocked by the people as soon as you came back." Li Shimin said.

"Yes, Your Majesty, it is normal for the people to be ignorant of Donghai Prefecture, worry, and worry. I think that the situation in Donghai Prefecture can be spread to every corner of the Tang Dynasty. After all, Donghai Prefecture is a newly established state capital, and we still need to The sense of identity of the Tang people." Yuan Shan said.

"The idea you mentioned is very good. Donghai Prefecture is the territory of Datang. Publicize the local situation to let the people know. Maybe some people are willing to go there. However, the population of Donghai Prefecture is too large. It is not enough for the people to apply for it on their own initiative." It can be solved, if you have any good ideas, please let me know." Li Shimin said.
