Doomsday Bunker Upgrade

Chen Xin is naturally ignorant of what happened to Qin Lan, and at this moment he is still on his way home.

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

Although there are no other shelters and supply points on the way back from Anhui Province, along the same road where Chen Xin came before, so that the material consumption is a bit large and must be replenished, but Huanggang City is an important city in Hubei Province. , No matter what, there are shelters where supplies can be supplied.

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

To this, Chen Xin just replied: "I have an appointment with someone when I come, and I will go to Sanzhen when I go back."

Hearing Chen Xin say this, Han Ping didn't say much. He was just expressing his doubts, and he didn't want to interfere with Chen Xin's decision.

For Han Ping, he is Chen Xin's driver. It is his responsibility to ask questions, but it is Chen Xin who makes the decision. Since Chen Xin has already made a decision, he only needs to implement it.

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

Handing over the driving to Han Ping, Chen Xin turned around and walked towards the living cabin at the rear, intending to take a rest.

With the addition of Han Ping and Han Ze, the biggest advantage for Chen Xin is that he is much more relaxed, and most of the things can be left to these two brothers, and he only needs to issue orders.

The elder brother Han Ping was in charge of driving, and the younger brother Han Ze was in charge of the co-pilot. At first, the two brothers were a bit jerky about this car, but after getting familiar with the way of driving this car, they were able to do their jobs well and let them Chen Xin can rest assured to leave all the driving matters to them.

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 walked over and asked his father, "Dad, what are you doing here? My mother Woolen cloth?"

"Your mother is resting on it." Chen Xin's father pointed to the top of his head, then looked at the planting box in front of him and asked Chen Xin, "Does this thing need to be watered every day to grow vegetables?"

"This, you don't need to water it every day. It has its own irrigation function. It will drip irrigation according to the soil humidity and crop growth, so as to ensure the water needed for crop growth without overwatering." Chen Xin explained a sentence.

Hearing what Chen Xin said, Chen Xin's father couldn't help showing an expression of amazement: "The technology is so advanced now that you don't even have to do it yourself."

"Yeah, technology is developing very fast." Chen Xin nodded in agreement, echoing his father's words.

Talking about this topic, Chen Xin's father didn't know what to think, and suddenly asked Chen Xin, "Son, do you think mankind will perish?"

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

"But now there is no sunshine and no farming, and the weather is still so cold outside, how can human beings survive?" Chen Xin's father obviously had a hard time accepting Chen Xin's answer, or he wanted to get something from Chen Xin that could convince him. The reason, he still asked Chen Xin.

"The dust in the sky will spread out in a few years. Although the dust in the stratosphere may not fall for hundreds of years or even thousands of years, the dust in the troposphere will almost fall in ten or eight years. It was re-photographed on the ground." Chen Xin also asked Zhang Chengguang and the others related questions before, and when his father asked, he naturally answered in the affirmative.

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

The matter lifted by the meteorite impact is distributed in the entire atmosphere and the low-Earth orbit of the blue star, from the bottom troposphere of the atmosphere to the topmost exosphere, which is densely distributed. It is these dust and debris that cover the the sky, so that sunlight cannot reach the ground.

Among them, the relatively large size and weight of debris will be the first to fall to the ground due to the influence of gravity, and burn up due to atmospheric friction.

The rest of the dust falls in succession depending on its altitude in the atmosphere.

The dust located in the troposphere at the bottom of the atmosphere will be the first to fall, and the dust in this layer is also the densest. When the dust in this layer settles, the surface will transform from a non-light environment to a low-light environment. 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 human acceptable levels within a decade.

Chen Xin explained to his father about sunlight, and then added: "Sunshine is not the most critical factor restricting human beings. With the technology currently mastered by human beings, although ten years without sunlight will cause great damage to human civilization. A lot of people will die from lack of food and the cold, but not to the extent that humans can be wiped out.”

Hearing Chen Xin say this, his father was obviously relieved a lot. The hardships he faced after the disaster were not difficult, but the lack of hope and future was the most unbearable.

Chen Xin obviously understood this, so he said to his father: "The country is now starting to rebuild after the disaster, and the towns below may not feel anything, but big cities like the three towns are gradually recovering. The living conditions may be a little tougher right now, but the future will definitely get better!”

"You don't need to comfort me, kid. I have suffered a lot more than your generation. It's not your turn to comfort me with this kind of thing." Chen Xin's father's face was a little embarrassed, but he still maintained his fatherhood. majesty.

While the 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 take a look, we have received a signal from Sanzhen. , they seem to be testing some kind of equipment."

"Sanzhen is testing the equipment? We are still a long way from Sanzhen, right? Can we receive their signal now?" Chen Xin was shocked and returned to the cab with Han Ze.

In response to Chen Xin's question, Han Ze hurriedly introduced the situation: "I was debugging the radio station just now to see if I could receive a signal, and as a result, I received a communication from Sanzhen, but they didn't send it to us. It was supposed to be a test that turned on a high-power signal source, and we just happened to be within the signal coverage."

Chen Xin nodded slightly. After understanding the situation, he sat directly in the passenger seat and said to the console: "System, replay the signal received just now."

"Signal playing..." The electronic sound of the system sounded, and a signal was replayed at the same time.

"...long...communication...trial, third...test..." The signal didn't seem to be very clear, but it was still generally audible.

Chen Xin listened to the intermittent signal played by the system, and roughly understood what was going on.

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

Chen Xin didn't feel anything strange about this matter. There are so many scientific research institutions in the three towns, and it is not a strange thing to do a communication test.

As for saying that your car is shrouded in the signal coverage, it is not surprising. This means that the satellite signal cannot be received in this environment. Otherwise, it is strange that there is no signal.

"They are doing a communication test, so let's just leave it alone." Chen Xin confirmed what was going on, so he didn't care anymore, said something to Han Ze, and stood up to leave the cab.

However, at this time, a new signal was received on the console: "Thanks to... the adjustment by that... Chen Xin... Sheng... This set of... equipment is finally... to achieve long-distance... information."

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

It sounds like it has something to do with the communication equipment that I adjusted when I was in the three towns last time, so are they testing the equipment they adjusted?

Chen Xin thought about what was going on after just a little association, so he reached out and picked up the walkie-talkie on the console. I put down the call button and said, "I seem to have heard someone mention my name. It seems that the device I adjusted last time 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 quickly responded, "Mr. Chen Xin, are you back from Anhui Province? "

"Yes, I'm on my way back now, and I should arrive in Sanzhen 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. already."

"No no, Mr. Chen Xin, if possible, we hope you can help us test the new equipment!" The other party obviously did not intend to let Chen Xin quit just like that.

The researchers who have seen how Chen Xin modulates the equipment instantly will not let go of such a powerful foreign aid as Chen Xin, and Chen Xin is just outside the three towns right now. With his help, he can test the signal stability of the equipment when the target is moving. A very important test, it can save them a lot of trouble if Chen Xin can help.

"Okay, how can I help?" Chen Xin was not stingy. Anyway, it was just a little effort, and he was idle on the road.
