Chapter 72

Zhou Xue glanced at him, took out a novel and read it for herself.

The car drove quickly.

This car is obviously a little old, and the car engine seems to be an asthma patient who is out of breath. It makes a "Kutong Kutong" sound. Chen Shouyi is a little worried about whether he will break down halfway.

After lying for about half an hour, he opened his eyes and looked out of the window.

Outside is an industrial area, with chimneys and a lot of white smoke.

Pingqiu city is not far from ningzhou, and it has entered the scope of ningzhou.

Compared with PingQiu City, which is still depressed, the traffic flow here has recovered, but it is still much less than before.

"Master, I heard that some factories here use steam engines?" Then someone on the bus asked the driver.

"Those who are smoking are basically!

At present, the electricity in ningzhou can only supply residential areas and some industrial areas. Most factories can only generate electricity by themselves, or use steam engines and transform machine tools. In this regard, it is said that the government has subsidies and interest free loans. " The driver said.

"This is really..." the passenger didn't know how to express his feelings: "I thought it was fake."

"In fact, steam engines are also good. You see, thermal power plants and nuclear power plants are not powered by steam turbines, and the steam engines in factories are not the same as before.

At least it is a subcritical steam engine. A steam engine can drive hundreds or even thousands of heavy-duty machine tools. It's much cheaper than generating electricity by yourself! "

As a former senior 3 student, Chen Shouyi still knows roughly what subcritical steam engine means?

In the process of heating and gasification of water, as the pressure in the boiler increases, the saturation temperature of water will also increase, and the gasification efficiency will decrease. When the pressure increases to a certain extent, the steam will be saturated and no longer gasified. The density of steam and water is the same, which is to reach the critical state.

If the pressure and temperature continue to rise, it will be completely vaporized into steam at this time. There is no difference between steam and water. Water is steam, steam is water, and it will become supercritical.

Subcritical is approaching critical state, which is an extremely mature technology.

As for today's thermal power plants and nuclear power plants, they basically use supercritical units, even ultra supercritical units.

However, the thermal efficiency of even subcritical steam engines is already extremely high, far beyond that of steam engines a hundred years ago.

But clearly, looking at the chimneys outside, Chen Shouyi still felt heavy in his heart.

This is the slow decline of human civilization.

After all, electricity is the cleanest energy for human beings.

If foreign forces continue to invade, once electricity is completely unavailable, not only will the prosperous and convenient era of information electrification become a history of civilization, but also all industries, including metallurgy and chemistry, will also suffer a serious recession.

The whole world will become dark.

He looked out the window at the chimney with white smoke, as if he saw the afterglow of a civilization that was about to decline.

There is no reason to feel a faint sadness in my heart.

……

The car continued to drive for half an hour, and finally came to a stop.

Chen Shouyi and Zhou Xue got off the bus together, walked out of the station and saw many taxis outside:

"Together?" Chen Shouyi asked.

Zhou Xue nodded and said, "well, carpooling together saves money!"

After all, it's a 15-year-old girl. It's estimated that she has never been to ningzhou.

Of course, he didn't, but he was much braver than her. He put his backpack behind him in the trunk and sat in the cab:

"Master, go to Wudao assessment center."

The driver quickly started the car and said, "I've picked up several times today, all of which went to the Wudao assessment center."

"Are there many people?" Chen Shouyi asked.

"Many! Most of them came from other places. I heard that this assessment will reduce the requirements!" The driver seemed to be well informed.

"Really?" Hearing this, Zhou Xue hurriedly asked.

"It must be. You think, when so many people come and take the exam one by one, the requirements must be relaxed."

Zhou Xue was not sure about the examination at all. Hearing the good news, she couldn't help but feel happy.

Chen Shouyi didn't care whether it was difficult or simple this time, and then asked:

"Is there a hotel near there?"

"There are many, but I guess they are full!"

"Go and ask there first, and then we'll talk about it."

The car arrived at its destination soon.

"The building in front is the Wudao assessment center, a total of 125."

"So expensive!" Zhou Xue in the back exclaimed.

"How fresh it is. Now the fuel cost has doubled, and now the fuel consumption of driving is also high. You see, I have punched the meter." The driver shouted.

Chen Shouyi didn't argue and directly took out his wallet to pay.

After receiving the change, he took out his luggage and that of the other party from the trunk and waited for her to get off.

"It's too expensive. I knew I'd take the bus." After lifting down Li, Zhou Xue also said repeatedly, looking distressed, and then took out a wallet: "here you are, this is 70 yuan! You can find me 8.5 yuan."

After taking it, Chen Shouyi put it in his wallet and said:

"No change, owe it first."

"You just received five yuan of the driver's change. Give it to me first."

Chen Shouyi reopened his wallet and found that there were five pieces in it. After taking it out, he handed it over: "here you are!"

"Then you still owe me 3.5 yuan." Zhou Xue said with a serious face.

This girl is a little more serious.

Chen Shouyi was speechless: "don't worry, I'll pay you back when I open it."

……

They then began to look for hotels nearby, but they were either full or too expensive.

Chen Shouyi doesn't care. Since he got the gold, his life has always been moist and he has become a little extravagant in spending money.

But Zhou Xue was not satisfied.

"This one is more expensive than the previous one. There are three hundred and one single rooms for two days."

"I've been looking for it for more than two hours. Why don't I pay it for you? You don't have to pay it back." Chen Shouyi couldn't help saying.

"If you're impatient, you can go. Anyway, I didn't ask to be with me all the time." Zhou Xue's face suddenly cooled down.

Chen Shouyi had good conditions at home since he was a child. He had no worries about life and never worried about money. It is inevitable that he can't imagine how much pressure there is for an ordinary family, and it may be a single parent family, to cultivate a martial apprentice. At the same time, he is more sensitive than ordinary people about money.

Chen Shouyi reacted and quickly apologized:

"Well, I'm wrong, so keep looking!"

The two of them didn't talk any more and walked with their heads down. Finally, the familiar atmosphere became cool.

Then they searched for nearly half an hour, and finally found a hotel with the right price.

Looking at their ages, the beautiful waiter at the front desk had nothing different on his face: "do you need a couple room?"

Hearing this, Zhou Xue widened her eyes slightly, and a crimson color quickly appeared on her white face. She stammered, "I... we are not together, single room, I live for two days."

"Please show me your ID card, a deposit of 100 yuan and a room fee of 200 yuan, a total of 300 yuan."

After Zhou Xue finished the formalities, she took her room card and didn't wait for Chen Shouyi, so she took her luggage and walked to the elevator, as if she couldn't wait to prove to the front desk that the two were OK.
