While Chen Xin was thinking about how to make snow track wheels, the atmosphere in the city became increasingly tense.
Although the situation is calm on the surface, in fact, beneath the surface calmness is a huge wave that is ready to go.
At the entrance of each major shelter, there are strict checkpoints set up by city management personnel, police and armed police, and strict inspections are carried out on everyone entering and exiting.
Managers are responsible for conducting identity checks to ensure that everyone who passes through the shelter gate has a well-documented identity and has a shelter residence certificate and pass issued by the city.
This is a management system that was only implemented after the disaster. Although the pass and residence permit system was also implemented before, the control was not very strict. Just like the ID card before the disaster, many people usually would not even carry it with them, but if It needs to be strictly checked, but everyone must have it and be able to get it right.
The police are responsible for conducting security checks to ensure that people entering and leaving the shelter do not carry dangerous items or prohibited items. The armed police are responsible for maintaining order on the scene. Suspicious elements are arrested and detained by the police. Criminals who intend to cause damage or cause trouble are arrested by the armed police. If arrested, the priest who resists can be killed directly.
With the close cooperation between the three, although I cannot say that it is watertight, at least it looks orderly on the surface, and it is impossible for criminals with ulterior motives to fish in troubled waters.
Generally, shelters are so tightly guarded, and the shelter where the city hall is located is even more so.
As the current location of the city government office, it is also the headquarters of the Joint Investigation Team. The soldiers transferred from the Star City by the joint investigation team are stationed here in the city hall, so that the review and defense at the door of the city hall is higher than that of other shelters. The level is so high that not even a fly can fly in, even though there are no flies left now.
However, although the entry and exit of the shelter is very strict, if you don't come out and just stand at the entrance of the shelter and smoke a cigarette, it is relatively easy and simple.
Because the interior of the shelter is closed, it is very troublesome to smoke.
After all, smoking in a closed environment will leave a bad smell if the smoke cannot be dissipated, and smoking in a shelter can easily cause fires and other safety hazards.
Therefore, smoking inside the shelter is prohibited, but cigarettes themselves are not banned. However, if you want to smoke, you need to come to the entrance of the shelter and smoke in an area with better ventilation.
Considering that life in a doomsday environment is relatively stressful and there are more people addicted to smoking, each shelter has designated a small area at the door as a smoking area.
It’s just that the so-called smoking area is just a windy corner? Although there is no cold wind to roll up the ice and snow and slap it on the face? But standing to smoke a cigarette is basically the limit. Standing in this place for a long time? Two Isn’t the foot unconscious? It’s actually frozen in a physical sense.
But for smokers, being able to smoke a cigarette in this environment is also a very rare enjoyment. Although cigarettes are very expensive, they need to spend a lot of food and materials to exchange for them on the black market. Or do they have enough contributions and work points? You can get a very rare pack from the supplies distributed by the shelter every month.
This is naturally the case for officials who have just returned from a meeting in the city hall. Especially the boring and mental exhaustion caused by the long meeting, a cigarette can indeed have a refreshing effect.
Although as management they are not short of cigarettes, they still have to comply with the regulations and come to the smoking area at the door.
Because the smoking area is located inside the entrance checkpoint, the police and armed police responsible for the inspection just glanced here and paid no attention to it. The staff are even less likely to offend their superiors.
As a result, there were a few more smokers standing and smoking at the door of the city government shelter.
"Fortunately, I still have a cigarette, otherwise I would be really overwhelmed by the continuous meetings." The person who spoke was a slightly wealthy official, with a bit of Star City accent when speaking, indicating that he came from the provincial capital. identity of.
A city official nearby who was also smoking couldn't help but echoed: "Who says it's not the case! In this environment, how many cigarettes are there to smoke? Otherwise, people won't be able to bear the addiction."
Several officials took advantage of the breaks in the meeting to smoke. At this time, no one cared about their status or the difference between the provincial government and the city government. The few people chatting were all related to smoking.
However, the burning time of a cigarette is not long, and the break between meetings is also not long. Soon, several people have finished smoking their cigarettes and are ready to return to the shelter to continue the meeting.
But one of them is left behind? He doesn’t seem to want to go in yet.
This behavior naturally attracted the attention of others, and one of the officials asked: "Secretary Li, why don't you go in?"
"I'll finish smoking this cigarette before I go in." The person who was shouted raised the half-smoked cigarette in his hand and smiled.
The person who asked him naturally understood very well. Today is no different than before. A cigarette is very precious. It is natural to smoke it to the end. It is impossible to smoke it out halfway.
The other officials didn't ask any questions. A group of people who had finished smoking returned to the shelter one after another, leaving only Secretary Li who was still smoking.
However, half a cigarette lasted only a short time. By the time the others were almost gone, Secretary Li had almost finished smoking the cigarette in his hand.
He finished the last two puffs of his cigarette and threw the cigarette butts into the trash can nearby.
But just when Secretary Li was about to go back, he found that the shoelaces on his feet had come loose, so he squatted down and tied the shoelaces again.
Secretary Li finished tying his shoelaces, then stood up and walked inside the shelter. When he met the cleaner who came to clean, he nodded politely as a greeting.
The cleaner also greeted Secretary Li politely, and after he passed by, he came to the smoking area where a bunch of officials were smoking, swept the cigarette butts on the ground, and poured the contents of the trash can into his bag.
There was nothing suspicious about this, so neither the police nor the armed police at the door paid attention here. They focused more on the outside of the shelter, watching everyone entering and leaving the shelter vigilantly.
However, no one noticed that when the sanitation worker put the trash can back, he already had a note in his hand.
The sanitation workers cleaned up the floor and then walked back to the shelter carrying their bags filled with garbage.

In Chen Xin's shelter, Chen Xin quickly drew the design of the snow track wheels.
The connection between the snow track wheel and the wheel is still a problem, but after Chen Xin thought about it, he decided to add a chain to the bottom of the car and a fixing rod to the wheel hub to increase the fixing points, plus the clips on the wheel. The snow track wheels are fixed on the wheels and will not slip off.
As for removing it when it is no longer needed, you only need to unfasten the fixing rod on the wheel hub and the chain on the bottom of the car, then fix the snow track wheel, and pull the wheel out of the snow track wheel.
Chen Xin looked at the drawings he drew and felt that they should not be much different from the originals. Even if there were some differences in structure and details, they were all minor matters.
The next question is of course how to make this thing. Part processing is naturally not a problem. With the system, Chen Xin can easily get the parts he wants, but he still can't make the track without rubber.
Rubber was a very common industrial material before the disaster, and various rubber products also filled people's lives.
As an important industrial raw material, whether it is natural rubber raw materials from Southeast Asia or chemical rubber obtained through petrochemical technology, it was very easy to obtain before the disaster.
But unfortunately, now after the disaster, it is somewhat difficult to obtain rubber.
Except for the rubber raw materials that remained before the disaster, there is probably no natural rubber. After all, even if the rubber trees were not burned, now that the world has entered the Ice Age, those rubber trees have lost their growing environment, and no one is tapping the rubber.
On the other hand, chemical rubber should still be produced in the country. After all, it is a very important industrial raw material that is used in various aspects. Even if chemical rubber is not as good as natural rubber, in today's environment, it is impossible to build a dedicated plantation. The greenhouse is used to grow rubber.
According to Chen Xin's estimation, the country should have preserved some industrial facilities and oil wells before the disaster. With these preserved industrial facilities, production should have resumed after just half a year.
It's just that traffic everywhere is now in a semi-isolated state. Only railway transportation can still operate. When the entire road network is almost paralyzed, even if rubber is produced, it will be shipped to the places that need it most without wasting precious rubber. Production capacity and transportation capacity are sent to non-key industrial cities like this city.
Although there are many large chemical plants in this city, which are important industrial production enterprises, in previous disasters, chemical plants around this city were affected by fires. It is difficult to estimate how much equipment can be saved.
After all, the chemical plant itself is a flammable and explosive place. This is something that Chen Xin, who has grown up in a chemical plant since childhood, is very familiar with.
Therefore, the city's industrial base is now almost gone. Only the factory areas under the city government can produce some materials needed for various shelters. Among these products, there is no chemical rubber, and even if there is, it is not something Chen Xin can get. .
Therefore, if Chen Xin wants to use rubber tracks, the only way is to get the rubber products that were left before the disaster and use the system function to extract the rubber that can be used as raw materials.
The most suitable rubber product is naturally tires. (End of chapter)
