The first rebel of the Tang Dynasty

"Come, aunt, mother, Wang Guifei, drink tea! This is my new tea, it tastes very fragrant!"

Li Yin gestured.

At this time, there were already a dozen cups of tea on the table.

The three picked up the tea cups and took a sip.

They didn't say anything, and they didn't care how good the tea was, because all they wanted to know was the helicopter.

So, they quickly put down their glasses.

Empress Changsun looked at Concubine Yang.

Concubine Yang understands.

sidewalk:

"My son! What is that helicopter you're talking about? Can you tell Mom?"

Empress Changsun followed her words and asked: "Yes, what kind of existence is it that can go to the sky, it makes people feel shocked."

And Concubine Wang Guifei just watched from the side without saying anything.

After all, her words have no effect here.

There is no need for Li Yin to hide.

He said: "Helicopters are the next generation of transportation. They can be widely used in transportation, patrolling, tourism, ambulance and other fields, but they are still under research."

Helicopters have many advantages that are difficult or impossible for other aircraft, and are widely used. Helicopters are mainly used for sightseeing, fire rescue, sea first aid, anti-smuggling and anti-drugs, fire fighting, business transportation, Medical assistance, communication, and spraying pesticides and insecticides to eliminate pests, detect resources, and other sectors of the national economy.

The reason why Li Yin researched this thing is mostly because of its relatively small technical barriers.

Of course, for Li Yin, the future will be very difficult.

Because of research.

But now he can get future information at will.

In the manufacture of some parts, helicopters are indeed a little faster than other aircraft.

Another point is that its speed is not fast, unlike a fighter plane, which can reach a speed of thousands of kilometers at every turn.

The three were startled.

This generation of ground transportation has not been popularized yet, and the next generation is about to be created.

Sheng Tang Group's thinking is really advanced.

Of course, if his thinking is not advanced, how could Sheng Tang Group become so advanced?

In fact, there are still many things that need to be improved.

But these things have to be done step by step, not too radical.

"Then how fast can it fly? How far can it fly? How high?" Empress Changsun asked again.

This question has only a few words though.

But it asked the most important data.

I dare say she was instructed by Li Shimin.

You know, just now Li Shimin saw the helicopter drop directly and rapidly from an altitude of 100 meters, down to about ten meters, and the flying speed was extremely fast, flying tens of meters away in just an instant.

This is hundreds of times better than a hot air balloon.

Therefore, she was asked to specifically ask these three key questions.

Now that they all know, Li Yin has nothing to hide.

The common people also know it, so it doesn't hurt to release some data in advance.

In this way, it creates a foundation for the commercial use of helicopters.

Although the future pricing will be high.

The price is high, and few people can afford it now.

It does not mean that fewer people will buy in the future.

He believes that people will earn more and more money in the future.

There will be more and more billionaires.

So, he said: "This helicopter, I want to design it to have a speed of 15 miles per hour and a height of [-] miles. In the past, the flying distance reached [-] miles."

Li Yin said so.

The three were quite shocked.

However, they only have a little feeling for the height. After all, 15 miles is an altitude of nearly eight kilometers, but they have no special feeling for speed and distance.

Because for these data, they are not cold.

Empress Changsun asked again: "Can you explain it with an example so that we can understand it better?"

Li Min thought for a while.

"Let's put it this way, it only takes three hours to fly from here to Qingzhou and back again! Six hours! For example, if you have breakfast before six o'clock in the morning, you can come back for lunch at noon."

That said, it's pretty clear.

Judging by the current train, it takes at least ten hours to go to Qingzhou.

It takes a day to go back and forth.

I have to stay in the car all day, which makes people feel that there is not enough time.

And this thing can go back and forth in as little as six hours.

But it is very powerful.

"How long will it take to reach Nvtang?" Concubine Yang suddenly asked.

How did Li Yin feel that she did it on purpose.

At the same time, the faces of the five women around him were a little unhappy.

Wang Guifei didn't notice either.

She didn't know the relationship between Li Yin and Nv Tang.

She probably thought that Concubine Yang was asking for Li Shimin.

Li Yin said with a serious face: "It takes three hours to arrive! If you go in the morning, you will arrive at noon, and if you come back, you will leave at night, that is, leave before breakfast and come back for dinner in the evening."

"That's half a day to go back and forth!?" Concubine Yang asked.

"Yes! Mother, but if there is no oil there, you may not be able to come back. You have to add oil!" Li Yin added.

"In this way, Qingzhou is considered to be between Nvtang and Chang'an! It's in the middle." Empress Changsun said suddenly.

"If you are afraid of running out of oil, you can start from Qingzhou and go back and forth with Nvtang! It's also possible, isn't it?" Concubine Yang said.

"It is indeed possible, my sister is really smart!"

The two actually chatted.

At this time, Li Yin's five wives were a little unhappy.

Because they were afraid that Li Yin would leave Qingzhou for Nütang.

After all, the middleman came here once, and Li Yin also said that he was going to Nvtang.

As time gets closer and closer, maybe Li Yin has already made plans.

It is to borrow a helicopter to go.

After all, if you take a boat, the speed is not fast, and the second will attract attention.

It’s different if it’s a helicopter, you can set off at night.

Then it's six hours away.

It's so fast, you can go back and forth in the same day, it's not too good.

The key point is that the people below have found out, and it is impossible to attack.

Li Yin estimated that he also wanted to go to Nvtang by helicopter without anyone noticing, but now he can't, because Li Shimin knew about it.

If he wants to go, he has to weigh it.

In fact, as long as he wants to do it, there is nothing wrong with it.

Empress Changsun and Concubine Yang chatted and seemed to find that the five women were not happy.

They understand, because there is no more to say.

If you continue talking, I'm afraid something will happen.

That is not one husband to one wife, but one husband to five wives.

If the five women are in a bad mood now, it may destroy Li Yin's relationship between husband and wife.

Therefore, the two of them stopped the topic just in time.

Instead, move on to another topic.

Empress Changsun said: "Ms. Min'er has a sentence here, I don't know if I should say it or not?"

Li Yin realized that something was wrong.

Next, is Empress Changsun going to do something?

But no matter what kind of move he makes, he has to accept it.
