Chapter 190: 1 small note

While Chen Xin was considering how to make snow track wheels, the atmosphere in the city became increasingly tense.
Although the surface is calm and the waves are calm, in fact, under the surface calm, there are huge waves ready to go.
At the gates of the major shelters, there are strict checkpoints set up by the city's administrative staff, the police and the armed police, to strictly check everyone who enters and exits.
The management personnel are responsible for the identity review to ensure that the identity of every person who enters and exits through the gate of the refuge is well documented and has a residence certificate and a pass issued by the municipal government.
This is a management system implemented after the disaster. Although there were also passes and residence permit systems before, the controls were not very strict. Just like the ID cards before the disaster, many people would not even bring them with them. It must be strictly checked but everyone must have it, and can match the number.
The police are responsible for security checks to ensure that people entering and leaving the shelter are not carrying dangerous or prohibited items. As for the armed police, they are responsible for maintaining order on the scene. Suspicious elements are handed over to the police for arrest and detention. Criminals who intend to disrupt or cause trouble are arrested by the armed police. Arrest, resist the priesthood can directly kill.
Under the close cooperation of the three, although I dare not say that the dripping water is not leaking, at least it looks orderly on the surface, and it is impossible for criminals with ulterior motives to fish in troubled waters.
General refuges are so tightly guarded, especially the refuge where the city hall is located.
As the current city government office location, it is also the resident of the joint investigation team. Soldiers transferred by the joint investigation team from Star City are stationed here, so that the inspection and defense at the entrance of the municipal government is higher than other refuges. Level, Jane has reached the point where a fly can't fly in, even though there are no more flies now.
However, despite the strict screening of entering and exiting the shelter, it is relatively easy and simple if you just stand at the door of the shelter and smoke a cigarette if you do not come out.
Because of the closed interior of the shelter, it is very troublesome to smoke.
After all, smoking in a confined environment will leave an unpleasant smell if the smoke does not dissipate, and smoking in a refuge can easily cause safety hazards such as fire.
Therefore, smoking inside the refuge is prohibited, but the cigarette itself is not banned, but you need to come to the door of the refuge to smoke in a well-ventilated place.
Considering that the pressure of life in the doomsday environment is relatively high and there are more people who are addicted to cigarettes, each shelter has a small area at the door as a smoking place.
It’s just that the so-called smoking place is just a corner covered by the wind. Although there is no cold wind that will roll up the ice and snow and pat on the face, smoking a cigarette while standing is basically the limit. Standing in this place takes a long time. The foot is not to lose consciousness, but to be frozen in a physical sense.
But for smokers, being able to smoke a cigarette in the current environment is also a very rare enjoyment, although the cigarette is expensive and requires a lot of food and materials to be exchanged on the black market, or there are enough contributions and work points. A very rare pack can be obtained from the supplies issued by the shelter every month.
The same is true for officials who have just finished the meeting from the city hall, especially the boring and mental exhaustion caused by the long meeting. A cigarette can indeed have a refreshing effect.
Although they are not short of cigarettes as the management, they still have to comply with the regulations when they come to the smoking place at the door.
Because the smoking area is located inside the checkpoint at the door, the police and armed police in charge of the inspection just glanced here and did not pay much attention. The staff were even less likely to offend their superiors.
Ever since, there were a few more smokers standing and smoking at the door of the municipal refuge.
"Fortunately, I still have a cigarette. Otherwise, the continuous meetings will go on, people really can't stand it." The one who spoke was a slightly rich official who spoke with a bit of Star City accent, indicating that he was from the provincial government. identity of.
A city government official who was also smoking couldn't help but agree: "Who said it was not! In this environment, there are still a few cigarettes left to smoke, otherwise people will not be able to handle the addiction."
Several officials came out to smoke during a break in the meeting. At this time, everyone didn't care about their status or the difference between the provincial government and the municipal government. The few people chatted about smoking-related topics.
However, the burning time of a cigarette was not long, and the break during the meeting was also not long. Soon a few people smoked the cigarettes in their hands and prepared to go back to the shelter to continue the meeting.
It's just that one of them lags behind and doesn't seem to want to go in yet.
This behavior naturally attracted the attention of others. One of the officials asked: "Secretary Li, are you still not going in?"
"I'll finish smoking this cigarette before going in." The person who was shouted raised the cigarette in his hand that was only half smoked, and smiled.
The person who asked him naturally understood very well. Now it is no better than before. A cigarette is very precious. Naturally, you have to smoke it. It is impossible to extinguish it after smoking halfway.
Other officials didn't ask much. A group of people who had already smoked returned to the shelter one after another, leaving only Secretary Li who was still smoking.
However, the time of half a cigarette is very short, and when the others are almost gone, Secretary Li's cigarette is almost exhausted.
He finished the last two cigarettes and threw the cigarette butts in the trash can aside.
Just when the secretary Li was about to go back, he found that the shoelaces on his feet were loose, so he squatted down and re-laced them.
Secretary Li finished tying his shoelaces, and then stood up and walked inside the refuge. When he met the cleaner who came to clean, he nodded politely as a greeting.
The cleaner also greeted Secretary Li politely. After he passed, he came to the smoking place where a bunch of officials had smoked, swept the cigarette butts on the ground, and poured the contents of the trash can into his own bag.
This is nothing suspicious, so the police and armed police at the door did not pay attention to this side. They paid more attention to the outside of the shelter, watching everyone who entered and exited the shelter vigilantly.
However, no one noticed that when the sanitation worker put the trash can back, there was an extra piece of paper in his hand.
The sanitation worker cleaned the ground, and then walked back to the shelter with his bag full of garbage.

In Chen Xin's shelter, Chen Xin quickly drew the design of the snow crawler wheel.
The connection between the snow track wheel and the wheel is still a problem, but after thinking about it, Chen Xin decided to add a fixed point by adding a chain to the bottom of the car and a fixing rod on the wheel hub, and the clamps on the wheels will The snow track wheels are fixed on the wheels so that they will not slip off.
As for it, it’s easy to remove it if it’s not needed. You just need to untie the fixed rod on the wheel hub and the chain under 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 it should not be much different from the original. Even if there are some differences in structure and details, they are all small things.
The next question is of course how to make this thing. Parts processing is naturally not a problem. Chen Xin can easily get the parts he wants with the system, but he can't make shoes without rubber.
Rubber was a very common industrial material before the disaster, and various rubber products filled people's lives.
As an important industrial raw material, whether it is natural rubber raw material from Southeast Asia or chemical rubber obtained through petrochemical technology, it was very easy to obtain before the disaster.
But it is a pity that now after the disaster, it is difficult to obtain rubber.
Except for the rubber raw materials that survived before the disaster, natural rubber is probably gone. After all, even if the rubber trees were not burned, they have lost their growing environment in the ice age around the world~EbookFREE.me~not to mention. People are tapping rubber.
On the contrary, chemical rubber should be produced in the country. After all, this is a very important industrial raw material. It must be used in various aspects. Even if the quality of chemical rubber is not as good as natural rubber, it is impossible to specialize in planting in this environment. The greenhouse has gone to plant rubber.
According to Chen Xin's estimation, the country should have retained some industrial facilities and oil wells before the disaster. Relying on these preserved industrial facilities, after this short half a year, production should have been resumed.
It's just that the traffic everywhere is in a state of semi-cut off. Only railway transportation can go. When the entire highway network is almost paralyzed, even if the rubber is produced, it will be shipped to the places where it is most needed without wasting precious valuables. Production capacity and transport capacity are sent to non-key industrial cities like this city.
Although there are many large-scale chemical plants in this city, which are important industrial production enterprises, in the previous disasters, the chemical plants around the city were affected by fires. It is difficult to count how much equipment can survive.
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, can be said to be very familiar.
Therefore, the city has almost no industrial base now. Only the factory area under the jurisdiction of the city government can produce some of the materials needed for various refuges. Not to mention that there is no chemical rubber in these productions, even if there is, it is not something that Chen Xin can get. .
So 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 functions to extract rubber that can be used as raw materials.
The most suitable rubber products are naturally tires.
