The kite circled four times in the sky before Li Yi controlled it to glide down with the wind. It gradually approached the ground and then stopped.
Opening the buckle, Li Yi stood beside the triangular hang glider and panted. Flying in the sky was also very tiring.
The main reason was that he was more nervous and was afraid of sliding down. Should he come back up or wait for the people above to come down?
Everyone surrounded Li Yi and looked at him. Very good, he was alive. Looking at the kite, it was also very good and not broken.
"This thing is a kite. Many people tried to fly with a kite but failed, but Li Yi did it."
Wei Zhigu went forward and squatted down to touch the hang glider.
A hot air balloon could fly in the sky and an umbrella could slowly descend from the sky.
Now, with a big kite, it could still fly. As long as the wind was strong enough, it could fly very high.
"It looks scary flying so high, what if I fall …" Su Yi was scared. He definitely wouldn't go up and try it.
"It can be used in the military." Li Longji first thought of the military.
Find a high place and let the soldiers jump into the enemy's city or attack the enemy's Baggage.
"Can it always fly at a high place?" Bi Goo was more concerned about this matter. It could fly here and there to pass on information.
"It depends on the wind. If the wind is suitable, there will always be wind. No matter which direction it blows, an expert can control it."
Li Yi mentioned an expert. He couldn't and could only choose an area. If he suddenly flew far away, he would involuntarily lower his altitude.
Today, he could be considered to have performed above his usual standards. Otherwise, he would have fallen down the mountain.
"Is it easy to learn?" Empress Wang was interested.
Li Yi shook his head vigorously. "It's not easy to learn. First, you need to find a flat ground with wind and practice many times. Before that, you need to learn how to parachute first."
The probability of an accident was not high, but once an accident happened, the worst result would be a fracture.
In fact, the reason why people had accidents most of the time was because those people wanted to challenge a difficult move. Flying normally was very safe.
There was also a video that said that he didn't wear a belt and grabbed the bar to descend. In the end, he still fractured his hand.
"Can you take off from flat ground?" Li Longji thought of something.
"Wait for the wind. Use a horse to lead the kite. After it flies, it can circle. If it is led by a horse, it can continue to fly."
Li Yi said with a smile. Flying a kite was simple. Previously, he had learned how to fly a kite, and it was not high off the ground.
If you have the conditions to go to the wind tunnel, you can practice in the wind tunnel first.
"Good, train some people and use horses to pull them outside the city." Li Longji also smiled.
"What if the other envoys saw it? Especially the Tubo and the Turks? "Song Jing immediately thought of the reason.
If he showed it to others, they would be scared to death. For example, the Tubo and the Turks felt that it was simple. They would make their own kites and fall to their deaths.
Song Jing didn't think that any kind of kite could fly people. If Li Yi could take out a kite that could fly around, it must be very high-tech.
Just like a gun, a gun looked simple in structure, but in reality, it had many parts and was extremely difficult to process.
"Is it cold in the sky?" Princess Yongmu looked at Li Yi with admiration.
To be able to fly in the sky with a kite, many people only dared to think about it. It was like a dream.
"The weather is warm now. I will use a hot air balloon to bring you up to take a look." Li Yi shook his head. If it was cold, he would also say that it was not cold.
"Fly ~ ~ Fly ~ ~" The little fellow opened her arms and ran with her little legs, shouting as she ran.
"If there is something that can bring people up to the sky and land at any time, it would be great."
Bi Goo was also afraid of hang gliding and didn't want to play with it.
He was thinking about long distance air transportation. It was more convenient than using hot air and would not be affected by the wind.
"Wait, wait. Wait for me to build a diesel engine. I will run on the ground first. It will be developed together with the steam engine. Both of them are not easy to build! "
Li Yi was worried. He wanted to build a steam engine locomotive, but it was not easy. He could build a small one first and use the same track.
The difficulty was that the parts were big and the boiler had to be thick enough.
If he changed to a diesel engine, the cylinder could be cast, and he had the blueprints for the parts inside.
The difficulty was that the parts were small. Many parts were small, especially the bearings, and the cylinder seal had to be tightly sealed.
First, he could build a single-cylinder engine and then add more. Then he would have a tractor.
The easiest way was to build a hand-held tractor. It was like riding a bicycle. The handlebars and brakes were all controlled by the handlebars.
But how to solve the problem of tires? Trains were not needed, tractors … …
"Xiao Yi, you said you can build it?" Bi Goo could not guess Li Yi's thoughts. He was surprised by Li Yi's words.
Li Yi said it was not easy to build, but he meant that he could build it.
"It's still early. I still need to build the foundation of the industry. I also need the Tang dynasty's navy to go out to the sea and bring back some things. It will take at least eight to ten years. "
Li Yi did not want to give them too much confidence. If they kept thinking about it and pondered about it all day, it would delay their work.
"Okay, eight years. Eight years it is. I want to live to see that day. Xiao Yi, work hard." Bi Goo gritted his teeth and agreed with eight years.
As for the ten years mentioned before, he pretended that he did not hear it.
"Let's go down the mountain and do our own things. Old Song, I know there are two new things. You have to be more open-minded." Li Yi looked at Song Jing.
"I'm fine." Song Jing was indeed open-minded. He was too far away from the people and did not make any achievements.
The people only recognized his position as the prime minister. They did not care about what he said.
He knew that he was the same as Yao Chong. His power was not in the hands of others.
However, when he saw the new gun, the gun that could make bullets fly a hundred feet away.
When he saw Li Yi fly a big kite in the sky, he was incomparable to Li Yi.
He came to play for two days, soak in the hot spring, receive a massage from Li Yi, and eat some comfortable food.
The group walked down the mountain. Li Yi took Princess Yongmu's hand and said, "Be careful. It's easy to go up the mountain, but hard to go down."
"There's a slide pole. It takes four people to carry it. Take a ride at a good place." Li Longji looked unfriendly, but he did not stop them.
Li Yi had to marry a wife, right? Marry who?
Marry my daughter. Then I'll change my name. It doesn't matter what my name is. The most important thing is to tie Li Yi to the royal family.
Princess Yongmu's face was red all the way to her neck. She lowered her head and let Li Yi pull her away.
Xiao Lan supported her on the other side and looked around with her big eyes.
The four ministers also walked by themselves. They did not look at Li Yi at all. They looked at the road and the scenery.
Li Longji thought for a moment, then took Empress Wang's hand and walked by himself.
The little girl sat on the slide pole. Everyone was protecting her. They were ready to catch the little girl with their own bodies at any time.
Guo Ziyi followed closely with his blade and a row of small throwing knives on his waist. He held Li Yi's sniper rifle in his hand.
"Guangping, the Japanese Empire is coming. Prepare to receive them and give the Japanese Empire a reward." Bi Goo discussed national affairs with Song Jing as they walked.
The Japanese Empire's vanguard team had arrived. There were six people, and it was said that the team would arrive soon.
They had left the Japanese Empire last year and had been on the road ever since.
There were more than three hundred people. The Japanese Empire's envoys in Chang 'an were ready to receive them at any time and present a letter of credence.
"Reward the Japanese Empire with books, scriptures, and technology. I want the head of whoever gives the Japanese Empire good technology."
Li Yi suddenly said. He did not care if the four ministers were in a good mood or not.
