Although Zhang Chengguang just came down from space, his hands and feet are in a state of powerlessness, and even his own walking belongs to gritting his teeth and insisting on it, he still dismantled the data memory in the re-entry capsule as soon as possible.

In Zhang Chengguang's opinion, the data storage is more important than himself and even the other two astronauts. That is all the observation data of the blue star from the space station Tiangong in the past half a year.

After the initial mission failed, they were unable to return to the blue star, so they took control of the spacecraft and went to the Tiangong space station, which used to be the operation support base.

Tiangong space station has a large amount of fuel and supplies for this mission. Although most of the fuel has been supplied to the three spacecraft flying to the meteorite in the previous mission, the supplies are still very sufficient.

After they arrived at the Tiangong space station, they tried to use the communication equipment on the Tiangong space station to get in touch with the blue star. Indeed, they once got in touch with the command center to observe the meteorological and other data of the blue star according to the requirements of the command center, so as to provide data support for scientists to analyze the impact caused by the meteorite impact.

But with the fall of the meteorite, the dust completely covered the entire blue star, and their communication was seriously disturbed, so they could hardly get any more contact with the ground.

In the next few months, although they had been trying to resume communication with the ground, they had little effect. They could only receive a little bit of ground signal sporadically, but most of them were disorderly civilian radio signals.

As for the communication with the command center, it has been unable to recover.

In a few months, they gradually exhausted the supplies in the Tiangong space station, but in desperation, they decided to risk using the return capsule to return to Bluestar.

It's almost a gamble, because they only have one return capsule. Once they start to return, there is no chance to fail again.

And landing failure, for them, is just a dead word.

The three astronauts didn't care about their own life and death. They were ready to sacrifice for their country long before they set out to carry out the mission.

However, they have to find a way to hand over a large amount of valuable data collected from the Tiangong space station to the state in any case, which is far more important to them than the lives of the three of them.

That's why they took the risk of landing in the densely populated area along the Yangtze River, rather than in the sparsely populated northern desert.

On the one hand, this is to facilitate rescue after landing. On the other hand, they are considering that in case of landing failure, their wreckage will fall in this area. As long as someone can find the re-entry module, the data memory in the re-entry module will also be found.

In this way, even if they are sacrificed, these precious data can still be returned to the surface of the blue star and sent to scientists.

However, they seemed to be lucky. When they landed, although the shell of the re-entry module had been hit by all kinds of debris and dust, so that the shell of the re-entry module had been smashed out of shape, but it was not damaged, and they were still sent back to the surface of the blue star very smoothly.

However, the situation on the ground is worse than they expected. If Chen Xin didn't happen to save them, the three astronauts with soft hands and feet would not be able to find refuge in the cold weather of tens of degrees below zero.

After all, even if they are strictly trained astronauts who have stayed in the space gravity free environment for more than half a year and suddenly return to the earth's surface, it is impossible for them to make a long journey in their space suits of more than 20 kg.

Not to mention that they have to face the ill intentioned survivors in the wind, snow and darkness, and hand over the data storage they bring back to the country.

Fortunately, they are really lucky to meet Chen Xin, who has the ability to help them, but also has no bad ideas for them.

Zhang Chengguang quickly disassembled the data memory. Although cheap disassembly was considered in the original design, in order to protect the data memory itself, it was fixed very firmly, and more than one had to be disassembled.

Zhang Chengguang's hands don't work hard. He does everything easily in a gravity free environment. After half a year, his body has been used to the gravity free environment. When he suddenly returns to the gravity environment, he can't help feeling that everything is hard to do.

But now is not the time to worry about this. He has to remove several data memories as soon as possible.

Zhang Chengguang's action is not slow. He said it took ten minutes, but it only took more than five minutes. Only the last two data memories needed to be disassembled were left. At his speed, he could do it all in three minutes.

Only at this time, Zhang Chengguang's ears also heard the sound of the car engine, the four cars have approached.

This made Zhang Chengguang anxious, but he didn't panic. He pulled the pistol on the side directly, and then continued to tear down the data memory against the clock.

Chen Xin and the other two astronauts on the car were also worried. They saw the four cars in sight earlier than Zhang Chengguang.These cars didn't hide their intention at all. The light of the headlights penetrated through the night and came directly. There was no arrogant cover up at all.

Chen Xin gritted his teeth. These four cars are no threat to him. His car has armor protection, even the windows are bulletproof, and there is a heavy machine gun on the roof. It can be said that Chen Xin is willing to solve these guys every minute.

However, the existence of the three astronauts makes him worry about exposing his heavy machine gun. If it's just pistols and other weapons, Chen Xin believes that the three astronauts won't go deep into anything, but the meaning of heavy machine gun is quite different. Even in this era of doomsday chaos, it's not something ordinary people can load into their cars.

However, if things come to a time of last resort, Chen Xin will not hesitate for such a small matter. Four ill intentioned cars and three astronauts will not let him catch up with him for the sake of confidentiality.

"I'll go down and help Lao Zhang!" An astronaut stood up and wanted to get off, but Chen Xin stopped him.

"It's more than 40 degrees below zero outside. You're looking for death if you go out like this!" Chen Xin's tone is not polite, and another astronaut also cooperate to pull the astronauts who want to get off.

It's more than 40 degrees below zero, which is extremely cold that the human body can't bear. Without enough protection, it only takes more than ten minutes to freeze a person, and it can directly freeze to death in half an hour.

That's why Chen Xin gave his protective suit to Zhang Chengguang to stop the astronauts from getting off the train.

As for the spacesuit that astronauts used to wear, although it has very good protective performance and the total weight is less than 20 jin, it takes more than ten minutes to put it on, so it's too late.

In this case, Chen Xin thought about it for a moment and then started his car. He put the car body between the direction of the four cars and the return cabin to form a protection for Zhang Chengguang.

However, Chen Xin didn't stop the engine. He just stopped the car. At the same time, he picked up the phone hanging on the console and handed it to the astronaut. He said to him, "you can shout to the outside. You can say something to scare those people first."

The astronaut immediately understood Chen Xin's meaning, and quickly, as he said, took the phone and yelled out. Chen Xin was also very impolite and turned on the loudspeaker outside the car to the maximum volume.

"Stop the traffic ahead now! Stop the vehicles ahead immediately! This is Yanguo space agency. It's on a secret mission! No one is allowed near! Please stop at once! Otherwise, we will take military measures to drive away! " Although Chen Xin and two astronauts were on board, the astronaut seriously pulled out the flag of the space agency.

For ordinary people, the space agency and secret missions are enough names to scare them from some ideas they shouldn't have. Even in today's Doomsday, Yanguo's national institutions still have full deterrent power.

Sure enough, under the bombardment of the loudspeakers, the four cars that had rushed towards Chen Xin's location all stepped on the brakes, braked on the snow and stopped several hundred meters away from Chen Xin's car.

Clearly, deterrence is working.

The four cars parked in the distance seem to be hesitating. If the other side rushes over regardless, Chen Xin can only turn over the heavy machine gun on the roof and blow them up one by one.

And now they stop, not only to save themselves, but also to keep Chen Xin from exposing the heavy machine gun.

However, no one knows how long this deterrent will last. Maybe these people will take risks in the next moment, or maybe the name of Yanguo space agency can scare them away. But for Chen Xin and the three astronauts, all they need is a few minutes' delay.

Seeing that the four cars just stopped and did not withdraw, Chen Xin signaled the astronauts beside him to continue to shout. At the same time, he launched a second UAV and approached the four cars with two UAVs, posing a threatening posture.

Chen Xin doesn't know who these people are, but no doubt his operation has calmed them down and made them dare not act rashly.

Zhang Chengguang, on the other side, naturally heard the sound. He quickly removed the last data memory, packed up his tools, held six data memories in his arms and was ready to take them away, but the heavy weight was not easy to take.

This makes Zhang Chengguang suddenly anxious, he almost did not hesitate to take off his protective clothing, put six memories in the protective clothing, and he climbed out of the re-entry capsule with the protective clothing.

The air-conditioning immediately eroded his whole body. Zhang Chengguang felt a piercing cold, but it didn't affect his movement. He rushed to Chen Xin's car quickly, and Chen Xin, who had been staring at this side, opened the door when he rushed.

Standing at the door of the car, two astronauts saw Zhang Chengguang rushing over and quickly reached out to pull him into the car.

Seeing Zhang Chengguang getting on the bus, Chen Xin quickly closed the door, and no matter what the reaction of the four cars was, he drove away from here with a bang of the accelerator.
