The big kite circled in the sky four times, and Li Yicai controlled the wind to slide down, gradually approaching the ground, and then braked with his feet.

Opening the buckle, Li Yi stood next to the triangular glider and gasped, flying in the sky was also very tiring.

The main reason is that he is more nervous and afraid of sliding down, will he come up again when the time comes, or wait for the people above to go down?

Everyone stepped forward and looked at Li Yi, very good, alive. Look at the big kite again, it's also good, it's not broken.

"This thing is a kite, many predecessors used kites to take off into the air, but Li Yi did it."

Wei Zhigu stepped forward and squatted down to touch the gliding wing, sighing with emotion.

Hot air balloons can fly into the sky, and umbrellas can slowly fall from the sky.

Nowadays, with a big kite, you can fly up, as long as the wind is strong enough, you can fly very high.

"It's scary to look at, fly so high, if you fall down......" Su Ying was scared and asked him to go up and try, he would definitely not go.

"Available in the army." Li Longji first thought about the military.

Find a high place, put soldiers from above, jump into the enemy's city, or go to the enemy's baggage.

"Can it always fly high?" Bi Gou is more concerned about this matter, and can fly around to pass on information.

"You need to look at the wind, the wind is suitable, there is always wind, no matter which direction it blows, the master can control it."

Li Yi mentioned a master, he can't do it, he can only choose an area, and suddenly fly to a distant place, he will involuntarily reduce the altitude.

Today, he is playing at a super level, otherwise he will fall off the mountain.

"Is it easy to learn?" The queen is interested.

Li Yi shook his head vigorously: "It's not easy to learn, you need to find a windy flat ground first, practice many times, or take off by traction, and learn to skydive before you do." ”

The probability of an accident with this thing is not high, but it is the worst fracture of an accident, and the ruthless one is gone.

In fact, the reason why someone has an accident is that most of the time is that those people want to challenge difficult movements, fly normally, and be safe.

There is also a video saying that he didn't tie the strap, and he grabbed the crossbar and went all the way down, and finally broke his hand.

"Can you take off on flat ground?" Li Longji thought of something.

"Wait for the wind, use the horse to pull the kite, and after flying, you can circle, and if you are always led by the horse, you can always fly."

Li Yi said with a smile that kite flying is simple, and you have to fly a kite before learning, and it is not high above the ground.

If you have the conditions to go to the wind tunnel, you can practice in the wind tunnel first.

"Okay, train some people and fly outside the city with horses." Li Longji also laughed.

"But let the other envoys see it? Especially the Tibetans and Turks? Song Jing suddenly thought of his intentions.

Show it to others, scare you to death. For example, the Tibetans and Turks feel that it is simple, and it is better to make their own big kites and fall to death.

Song Jing doesn't think that any kind of kite can take people to fly, and the kite that Li Yi took out and can fly around must have a high technical content.

Like the gun, the gun has a simple structure, but in fact there are many parts, and it is difficult to process.

"Is it cold in the sky?" Princess Yongmu looked at Li Yi adoringly.

can personally use a kite to spin in the sky, how many people only dare to think about it, like a dream.

"Now that the weather is warm and not cold, I will take you up in a hot air balloon one day." Li Yi shook his head, and he said that he was not cold.

"Fly~~Fly~~" The little guy spread his arms and ran upside down with his calves, shouting as he ran.

"If only there was something that could fly into the sky with a person, it could land at any time, and it wouldn't have to wait for the wind."

Bi Gou is also afraid of hang gliding and does not want to play.

He was thinking about long-distance air transport, which would be more convenient than hot air and not affected by the wind.

"Wait, wait, wait until I build the diesel engine, run on the ground first. Developed together with steam, neither of which is easy to make! ”

Li Yi's face was sad, he wanted to build a steam engine locomotive, it was not easy, he could build a small one first, and the track would be the same.

The difficulty lies in the large number of parts, and the boiler needs to be thick enough.

Replaced with a diesel engine, the cylinder can be cast, and he has drawings for the parts inside.

The difficulty lies in the small number of small parts, especially the high requirements of the bearings, and the cylinder seals must be tightly sealed.

Just build a single-cylinder one first, and then add it so that the tractor is there.

The simplest is a walk-behind tractor, like riding a bicycle, controlling the handlebars, and the brakes are all operated on the handlebars.

Just how to solve the tires? Train's don't use, tractor......

"Xiao Yi, you said you could make it?" Bi Gou couldn't guess Li Yi's various embarrassing thoughts, and he was surprised by Li Yi's words.

Li Yi said that it is not easy to build, and that it is not easy to build means that it can be made.

"It's early, I have to build a solid industrial foundation, and I still need the Datang Navy to go to sea and get things back. I don't have a ten-year-old dream. ”

Li Yi didn't want to give everyone too much confidence, if they were worried about it and pondered all day long, it would delay the right thing.

"Okay, eight years, eight years will be eight years, the old man wants to live, see that day, Xiao Yi, you work hard." Bi Gou gritted his teeth and recognized it for eight years.

As for the ten years mentioned above, he assumed that he had not heard of it.

"Let's go, go down the mountain, we are busy, we know that there are two new things, Lao Song, you have to look at it." Li Yi looked at Song Jing.

"The old man is fine." Song Jing really saw it, he was too far away from the people and didn't make any achievements.

The people only recognized his position as prime minister, and they didn't care about what he said.

He understands that he, like Yao Chong, has the same rights.

However, when I saw a new gun, a musket that could make bullets fly out of a hundred feet.

Seeing Li Yi get a big kite and fly in the sky again, he is not comparable with Li Yi.

Come and play for two days, soak in the hot springs, receive Li Yi's massage, and eat some comfortable meals, okay.

The group walked down the mountain, and Li Yi took Princess Yongmu's hand: "Be careful, it's easy to go up the mountain and difficult to go down." ”

"There is a sliding pole, a sliding rod carried by four people, and a car is taken in a good place." Li Longji's face was not good, but he did not stop it.

Li Yi can't help but marry his daughter-in-law, right? Who to marry?

Marry your own daughter, and then change your name, it doesn't matter what your name is, it is the most important thing to tie Li Yi to the royal family.

Princess Yongmu's face was red all the way to her neck, and she lowered her head to let Li Yi pull her away.

Xiaolan was holding on the other side, looking around with big eyes.

The four ministers also walked by themselves, not looking at Li Yi at all, looking at the road and the scenery.

Li Longji thought about it, took Queen Wang's hand, and also walked by himself.

The little one sits on the pole, surrounded by all the people who are protected, ready to catch the little one with his body at any time.

Guo Ziyi carried a knife on his shoulder, a row of small flying knives on his waist, and followed closely with Li Yi's sniper rifle in his hand.

"Guangping, the Japanese people are coming, prepare for the reception, and there is a reward for the Japanese country." Bi Gou discussed state affairs with Song Jing while walking.

The vanguard of the Wa Kingdom came, six people, and said that a large group of people would come soon.

I came out of the country last year, and I have been on the road ever since.

More than 300 people, the envoys of the Japanese state in Chang'an are ready to greet them at any time, and then send a letter to the country.

"Reward books, scriptures, and technology are not allowed to leak out, and whoever gives the country good technology, whose head I want."

Li Yi suddenly spoke, not polite at all, regardless of whether the four ministers were in a good mood or not.
