Terrible sirens sounded in all areas of Immigration One at the same time, and the red siren lights flashed rapidly.

Everyone in the activity center did not dare to delay, and they all rushed to the cabin where they were located. Space is not as good as on Earth, the slightest situation may be a big problem, they can't help much, it's best to stay in their own cabin, and the rest is just to resign to fate.

Li Chen followed the flow of people to his rest cabin, still carrying half a bottle of liquor and half a box of cigarettes in his hand, although the rest cabin could also order food directly. However, this kind of scarce material is really not something he can get, with these things, no matter how long this problem will have to be dealt with, at least for a short time, he doesn't have to worry about being bored in the rest cabin alone.

The precarious situation at Immigration 1 seemed to heal after about four hours, but the military's control room did not notify the passengers that they could come out. Everyone thought that the military was probably busy and forgetful, but everyone didn't dare to come out, so they stayed in the rest cabin and played games.

The passenger rest compartment has computers that connect to the entire ship's network, allowing passengers to communicate with each other even when they are not going to the activity center. Of course, this kind of communication is limited to verbal communication, and as for physical communication, it is still necessary to wait until the activity center is open and go to the double rest cabin of the activity center to achieve it.

Li Chen opened the computer in the rest cabin with a little expectation, the chat software on it is very funny, even if the manufacturers on the earth immigrate to Mars, they don't forget to advertise once, is it possible that they will have the opportunity to do business with the first batch of immigrants on Mars in their lifetime!?

The data in the computer has collected most of the knowledge about infrastructure, science and technology, medicine, production and life that can be recorded on the earth, and it is believed that as long as these 20,000 people are not stupid, even without the remote command of the Earth command, these 20,000 people can survive in the temporary space station on Mars.

Li Chen didn't look at these materials, he didn't know how different Mars was from what was recorded in the data. He had already learned everything he needed to know before boarding Immigration 1, and the most important thing to do on Mars was to survive first. Li Chen entered the operation simulation interface of engineering equipment in the computer, the earth has entered the 22nd century, compared with excavators and forklifts a few decades ago, the new engineering equipment is not just as simple as digging a soil.

The operation simulator opened by Li Chen is not a simple operation of engineering equipment, but a competitive type of game, and players participating in the game must use the limited resources in the game map to build a base and open up a territory, and finally the one with the highest score will win. Li Chen doesn't play this game in order to win, he tries his best to be familiar with the various engineering equipment in the game, every time he plays this game, he only uses one kind of engineering equipment, anyway, the engineering equipment is a multi-functional engineering vehicle, there is one that can barely complete the game task, but the difficulty level is different in different maps.

The engineering equipment in the game is all products that have been produced in the real world, and they are all carried on this Immigration One, in fact, this equipment will be used in the construction of Mars in the future. Li Chen understood that he couldn't learn superb medical skills, and he didn't want to understand any complex genetic engineering to grow food, and as for what scientific research and development had nothing to do with him, he decided to start with infrastructure construction, first learn engineering equipment thoroughly, and lay the foundation for his life on Mars in the future.

These engineering equipment has not developed like the original anime or film and television works can become humanoid mecha appearance, most of the engineering equipment can be described as engineering vehicles, of course, these engineering vehicles are not ordinary engineering vehicle image. These engineering vehicles are all bionic engineering equipment, either in the image of a beetle, or in the image of a water spider, centipede, etc.

This time, Li Chen used a construction vehicle in the image of a water spider, and the scene was still a boundless wilderness. This is not a suitable working environment, but fortunately, although the water spider is called a water spider, it can still burrow into the ground and work on the desert, but it is much slower than other engineering vehicles.

The detector starts working at a high frequency in the map, Li Chen has to find survival resources before the inherent resources are exhausted, the kinetic energy of the engineering vehicle is not to worry, and the high-efficiency solar panels and small nuclear power system are enough to complete a game. But the survival time of the characters is really the most important issue.

Deep underground, Li Chen succeeded in discovering water resources, with which he could synthesize food. The problem of the base is better solved, under the double-line operation, Li Chen explored the location of the water resources while digging holes in the soil layer above the water resources to prepare for the construction of the base.

"Boom!" Just when Li Chen was wholeheartedly familiar with the operation of the engineering vehicle and understood the use skills of the water spider engineering vehicle, he suddenly felt that the perspective at the top of the screen trembled. "There's an earthquake!?" Li Chen turned on the high-frequency mode of the engineering radar in confusion, and he vaguely found a small engineering vehicle in the shape of a beetle above him, which was actually covered with miniature bombs above him.

"! Can you still play like this!? Li Chen immediately understood the other party's intentions after seeing the dense bombs overhead.

Li Chen has only played this simulator a few times, and most of the time after he got on the spaceship was wandering around various living areas, he just thought that this game was used to let the immigrants get familiar with and understand the production tools, so he could come and grab the base so brazenly.

Li Chen is not a master to be bullied, although his engineering truck is not loaded with weapons, it is not difficult to defend. He strengthened the density of the soil layer above the base to minimize the damage to the base from the bomb's shock wave, and then began to use a 3D printer to create a honeycomb-shaped wall behind the first line of defense, which was to create an anti-resonance buffer layer, believing that the opponent would not be able to attack the base in a short time until he stabilized the base.

Above the "Boom! The sound was getting closer and closer, but Li Chen was not moved at all, he knew that although the other party had bombs, those were all for engineering use, and the power was not comparable to military weapons, even if the other party reached the defense layer of his base, it was enough for the other party to have a headache.

In a recreation cabin in the volunteer area, a voice shouted angrily, "What a person! Building a base is still so deep underground, is it a rat!? "The owner of the voice has always been fully armed when playing this game, and he has never mined by himself, and he will win by grabbing the unlucky guy closest to him and grabbing resources. But today he found the nearest engineering vehicle signal to himself but found that the other party was nearly 100 meters underground, but he did not install a large drill on his engineering vehicle, but could only use a small drill pipe to arrange a bomb to open the way, and the people below were scolded in his heart for being bloody.

Just when the owner of the voice was secretly cursing the players below, he suddenly heard a signal from the other party below, "Hey, brother above, are you tired!?" Would you like to come down and drink saliva!? You've finally arrived at my door, and it's not good for me to drive you away, isn't it? ”
