Time flies very quickly, and it takes nearly an hour without realizing it.

It took nearly an hour, although I didn’t fly at full speed, it was enough to fly back and forth between Mount Li and Chang'an, and to go around the city of Chang'an.

Li Er was quite satisfied.

However, he did not forget the main business. After returning to the village and visiting the plastic greenhouse built, he talked about the hydropower station.

Chen Yuan patted his head: "I lie to me, I always think this matter has been done. According to Brother Qin's wishes, how big will we do this time? Why don't we just go directly to the Ba River?"

Li Er guessed that was the case.

But I understand that after all, one of the hydropower stations has been built, and the village is not short of electricity at all. It is normal to forget about it as soon as there are too many things.

However, the Ba River was still a bit too big, although during this period of time, I found that there were indeed suitable places in the upper reaches of the Ba River.

He smiled and said, "Don't, let's try a few smaller ones first, get a few smaller ones first, accumulate experience, and wait until the time is right, get a big one."

Chen Yuan thought for a while and nodded: "Okay, just go to the larger ones. First, it is easy to encounter problems, and second, there is no place to consume the power when it is sent, so let's get the smaller ones first!

It just so happens that the water is dry in autumn and winter, so it is perfect to build a hydropower station at this time."

Li Er laughed: "What my brother said is very good, but in fact, I think so too."

After saying that, I directly ordered someone to bring a map specially: "Come on, please see, this is a map of the land of Chang'an. Brother Yu searched carefully these days and found that the generation of Zhongnan Mountain is good.

Zhongnan Mountain has been sparsely populated, with many mountains, streams, and steep mountains as its backdrop. It is an excellent place for hydropower stations to build..."

The map is a map.

Although Chen Yuan's eyes are very rough and he can't understand it at all, it is undeniable that Li Er is indeed very concerned and has done a lot of work for it.

Chen Yuan had no objection, and after hearing this, he said, "Then let's make a temporary appointment with Zhongnan Mountain. I will go and take a look, pick one first, fumble and accumulate experience."

Things settled.

As soon as Li Er left, Changle said worriedly: "Brother Chen, don't you really plan to bring the Duke of Jin and his wife to Qiongzhou together, are you?"

Chen Yuan drank the hot orange juice: "It's not that I want to take them there, it's because Duke Jin had to pester them. Besides, I really want to go there. I want to plant the trees and take a vacation by the way. After all, it's warm there."

After saying that, he stroked Changle's black and beautiful hair and smiled, "Why, are you worried about something wrong?"

Changle nodded: "Worried."

Chen Yuan laughed and hugged his little shoulder: "Silly girl, don't worry, nothing will happen. At worst, I will take them all away when something happens. Anyway, I won't fall to death."

Changle's starry eyes flashed, and he raised his little face: "Really?"

"Of course it's true, and I'm planning to change to a helicopter, a much safer helicopter." Chen Yuan said with a smile.

Yongjia came in with a fruit plate. When he heard it, he asked, "What helicopter is so safe?"

"Domestic, ac313, ac represents China AVIC Helicopter Company, 3, represents all things, 1, represents the technical level, and the last 3 represents the number of engines.

In other words, this helicopter has three engines. One can continue to fly if there is a problem, and two can still land nearby if there is a problem. Most helicopters, such as the ones we were riding before, were single-engine.

In addition, this helicopter flies across the plateau and over the high cold. It can fly at an altitude of 8,000 meters, and it can fly at minus 40 degrees Celsius. It also has an emergency floating system that can land on water."

The high rate of helicopter accidents is mainly the engine and the second is the environment.

My rabbit's usual character is that it is not only two engines that can use three engines, but also all kinds of high-altitude plateaus must be arranged.

After all, there are thousands of roads, and safety is the first. The heads and minds of the unit are not afraid of anything, but are afraid of death.

Yongjia said in surprise: "It's so amazing, why didn't you buy it before?"

"Yes, isn't it better to get it done in one step?" Changle also asked curiously.

Chen Yuan shrugged: "I didn't know at that time, and this thing is not cheap, it costs 80 million!"

"Eighty million?"

Even though they never took the money seriously, the aunt and nephew were still extremely shocked at this moment.

Because I have never bought such expensive things, the price of helicopters before was even one-tenth of 80 million.

To this day, they are more aware of what kind of purchasing power 80 million is and how much they can buy.

Chen Yuan nodded with a smile: "Yes, 80 million, maybe it can't be beaten, but this thing is not only safe, but also big.

This is a large civilian helicopter, which can take up to twenty-seven people, almost an Airbus."

“Twenty-seven people?

No wonder it is so expensive, so large, with good safety performance, so it is strange if it is not expensive."

"Yes, but it's much easier to go out like this. Twenty-seven people, with more choices, can basically take care of them."

“…”

No surprise, I was surprised again.

But this is obviously good news, because safety is not only the safety of the fuselage when riding on the plane, but also the safety of the personal safety when walking in a foreign land after landing.

So just two days after returning, Chen Yuan went out again.

This time I went to Greece. Although it was made from domestic products, it was better to buy it outside.

This is not something that can be done every day or two.

Taking advantage of this opportunity, he traveled to Zhongnan Mountain, determined the construction address of the hydropower station, studied and determined the plan, and stayed for two days.

Then this matter was left to a group of the top engineers in the Tang Dynasty to practice.

Anyway, it is not a big project. If it is wrong, it will be corrected. If it really cannot be corrected, there will be no big loss.

It was the first time he officially stepped on Mount Li on Mount Li.

The lesson is about to be taught.

But it was not too formal. He just summoned everyone and spent a morning to help everyone open the door to the new world with auxiliary teaching equipment and instruments such as globe telescope and microscope.

The teachers in the village academy are left to do it for them. After all, these people have no foundation. What they need now is not advanced knowledge, but basic enlightenment.

There is no need to worry about not enough teachers.

Because the current education system is like the Imperial College, which is similar to that of modern universities.

There are very few teachers.

Especially for a doctorate, it is hard to say whether there is a class in three or five days.

It depends more on students' own efforts after class.

It doesn’t matter if you don’t work hard. You can take the exam for one ten-day exam, one month three exams, and one quarter exam every year. As long as you have the ability, you can pass the exam, and you can play whatever you like.

On the other hand, I’m sorry, you don’t care wherever you fight, and there is no need for us to care.

That's it.

So it's totally visible.

In this case, there is actually no need to worry about it in the future. Anyway, there are only a few classes a month.
