Chapter 265

Chen Xin naturally knows nothing about what happened to Qin LAN. At the moment, he is still on his way home.

"Mr. Chen, why do we go from three towns? If you go to Huanggang City, you can save a lot of time. " Han Ping studied the map in his hand, some of which didn't quite understand Chen Xin's choice.

Although there are no other refuges and supply points on the way back from Anhui Province along Chen Xin's road, so that the consumption of materials is a bit large and must be supplemented, Huanggang City, as an important city in Hubei Province, has refuges and supplies.

So Han Ping didn't quite understand why Chen Xin had to walk a long way around the three towns.

To this, Chen Xin just answered: "when I come here, I have an appointment with people. When I go back, I will go to three towns."

When he heard Chen Xin say so, Han Ping didn't say much. He just expressed his doubts and didn't want to interfere in Chen Xin's decision.

For Han Ping, he is Chen Xin's driver. Asking questions is what he should do, but it is Chen Xin who makes the decision. Since Chen Xin has made the decision, he just needs to implement it.

Unless Chen Xin's decision is too bizarre, in Han Ping's opinion, all he needs to do is implement it.

Hand over the driving to Han Ping, Chen Xin turns around and goes to the rear living cabin, intending to have a rest.

With the addition of Han Ping and Han Ze, the biggest advantage for Chen Xin is that he is much more relaxed. Most of the things can be done by these two brothers, and he just needs to give orders.

Han Ping, the elder brother, is responsible for driving, while Han Ze, the younger brother, is responsible for acting as the co driver. At first, the two brothers are still a little unfamiliar with the car, but after they are familiar with the driving style of the car, they are already competent for their work, so that Chen Xin can rest assured to give them all the driving matters.

Back in the living cabin, Chen Xin saw his father standing in front of the planting box, as if he wanted to water the vegetables inside. So he went to his father and asked, "Dad, what are you doing here? Where's my mother? "

"Your mother is resting on it." Chen Xin's father pointed to the top of his finger, then looked at the planting box in front of him and asked Chen Xin, "do you need to water this vegetable every day?"

"Well, it doesn't need to be watered every day. It has its own irrigation function. It will drip irrigation according to the soil moisture and crop growth, so as to ensure that the water needed for crop growth will not be over watered at the same time." Chen Xin explained one sentence.

Hearing Chen Xin say so, Chen Xin's father couldn't help showing a pair of exclamation expression: "now technology is really developed, even watering don't have to do it yourself."

"Yes, the development of science and technology is very fast." Chen Xin nodded in agreement, echoing his father's words.

Talking about this topic, Chen Xin's father didn't know what he thought of. He suddenly asked Chen Xin, "son, do you think human beings will perish?"

"No Chen Xin gave the answer to his father's question without even thinking about it.

"But now there is no sunshine, and we can't farm. It's still so cold outside. How can human beings survive?" Chen Xin's father obviously finds it difficult to accept Chen Xin's answer, or to get convincing reasons from Chen Xin. He still asks Chen Xin.

"The dust in the sky will disperse in a few years. Although the dust in the stratosphere may not fall down for hundreds or even thousands of years, the dust in the troposphere will almost fall down in ten or eight years, and the sun will shine on the earth again at that time." Chen Xin also asked Zhang Chengguang some related questions before. When his father asked, he naturally answered in the affirmative.

Before landing on the blue star, Zhang Chengguang used the observation equipment of the space station to observe the blue star for more than half a year. According to their observation, the blue star was surrounded by a large amount of dust and debris formed by meteorite impact.

The materials raised by the impact of meteorites are distributed in the whole atmosphere and the near earth orbit of blue stars. From the troposphere at the bottom of the atmosphere to the outer escape layer at the top, they are densely distributed. It is these dust and debris that shield the sky and prevent sunlight from reaching the ground.

The debris with large volume and weight will first fall to the ground due to the influence of gravity, and burn up due to atmospheric friction.

The rest of the dust will fall one after another according to its height in the atmosphere.

The dust in the troposphere at the bottom of the atmosphere will be the first to fall, and the dust in this layer is also the most dense. When the dust in this layer settles, the surface will transform from a dark environment to a low light level, and the light intensity will gradually increase.

Although the dust in the upper atmosphere will be difficult to fall because the upper atmosphere is mostly translational, the light will still return to the acceptable level within ten years.

Chen Xin explained to his father about the sun, and then added: "the sun is not the most critical factor restricting human beings. In terms of the science and technology currently mastered by human beings, although ten years without sun will have a great impact on human civilization, many people will die because of lack of food and cold, but it is not enough to destroy human beings."Hearing Chen Xin say so, his father is obviously relieved. After the disaster, the hardship he faced is not hard, but the lack of hope and future is the most unbearable.

Chen Xin obviously understood this, so he said to his father, "the country is now in the process of post disaster reconstruction. The towns below may not feel much, but big cities like the three towns are gradually recovering. Perhaps the present living conditions will be a little harder, but they will certainly be better in the future! "

"You don't have to comfort me. I suffer more than your generation. It's not your turn to comfort me." Chen Xin's father has some embarrassment on his face, but he still maintains his dignity as a father.

While father and son were still talking about this topic, Han Ze suddenly ran over from the cockpit and said to Chen Xin, "Mr. Chen, come and have a look. We have received the signal from the three towns. It seems that they are testing some equipment."

"Where's the testing equipment in three towns? We're a long way from three towns, right? You can get their signal now? " Chen Xin was shocked and went back to the cab with Han Ze.

As for Chen Xin's question, Han Ze quickly introduced the situation: "I was debugging the radio station just now to see if I could receive the signal. As a result, I received the communication from the three towns, but they didn't send it to us. They should be doing some testing. They started a high-power signal source, but we were just in the signal coverage."

Chen Xin nodded slightly. After understanding the situation, he directly sat in the co pilot's seat and said to the console, "system, replay the signal just received."

"Signal playing..." The system's electronic audio starts, and a signal is replayed at the same time.

“… Long Communications In the test, third Test... " The signal doesn't seem very clear, but it can be heard clearly.

Chen Xin listened to the intermittent signals played by the system and generally understood what was going on.

As Han Ze said, this should be a test, and his car only received the signal when it was within the signal coverage.

Chen Xin didn't find it strange about this. There are so many scientific research institutions in the three towns, so it's not strange to do communication testing.

As for saying that your car is shrouded in the signal coverage, it's not surprising. That is, the satellite signal can't be received in this kind of environment, otherwise it's strange that there is no signal.

"People are doing communication tests, so let's leave it alone." Chen Xin confirms what's going on, so he doesn't care any more. He says to Han Ze, and then stands up to leave the cab.

However, at this time, the console received a new signal: "thanks On That Chen Xin The adjustment of students This set of The end of the equipment To achieve long distance I've heard from you

Hearing this, the expression on Chen Xin's face couldn't help showing his interest. Is it still related to him?

It seems to have something to do with the set of communication equipment that they adjusted when they visited Sanzhen last time. Are they testing their adjusted equipment now?

Chen Xin just a little association, then thought of what is going on, so he reached out and picked up the intercom on the console, a little operation, his car's signal is also connected to the other party's communication channel, pressed the call button, said: "I seem to hear someone mention my name, it seems that the last time I adjusted the equipment effect is not bad!"

"Mr. Chen Xin? Why are you on our channel? " The other party seemed very surprised that Chen Xin was able to access their communication channel, but soon responded: "Mr. Chen Xin, are you back from Anhui Province?"

"Yes, I'm on my way back now. I should arrive in three towns in two days." Chen Xin answered the other party's question and said, "are you testing the equipment? Then I won't disturb your work. "

"No, no, Mr. Chen Xin, if you can, we hope you can help us test the new equipment!" The other side obviously does not intend to let Chen Xin quit like this.

Researchers who have seen how Chen Xin modulates the device instantaneously will not let go of Chen Xin's powerful foreign aid. Moreover, Chen Xin is just outside Sanzhen now. It is also a very important test to test the signal stability of the device when the target is moving with his help. It can save them a lot of things to ask Chen Xin to help.

"All right, how can I help you?" Chen Xin is not stingy. Anyway, it's just a matter of lifting a finger. He is idle on the road.
