Doomsday Bunker Upgrade Chapter 190: 1 small note

When Chen Xin was thinking about how to make a snow crawler wheel, the atmosphere in the city became increasingly tense.

Although the wind and waves are calm on the surface, in fact, beneath the surface calm is a monstrous wave poised to break out.

At the gates of the major shelters, there are strict checkpoints set up by the city government's management personnel, the police and the armed police, and everyone who enters and exits is strictly checked.

Administrators are responsible for conducting identity checks to ensure that every person entering and exiting through the gate of the shelter is well documented and has a City-issued shelter-in-place and pass.

This is a management system that was implemented after the disaster. Although there was a pass and residence permit system before, the control was not very strict. Just like the ID card before the disaster, many people usually don't even bring it with them. , But if you want to strictly check it, everyone must have it, and it can match the number.

The police are responsible for conducting security checks to ensure that people entering and leaving the shelter do not carry dangerous or prohibited items. As for the armed police, they are responsible for maintaining order at the scene. Suspicious persons are handed over to the police for arrest and detention. The armed police are responsible for the arrests, and the rebellious priesthood can directly kill them.

With the close cooperation of the three, although I dare not say that there is no leakage, at least on the surface it looks orderly, and criminals with ulterior motives will never be able to fish in troubled waters.

General shelters are so heavily guarded, especially the one where the city hall is located.

As the current location of the city government office, it is also the location of the joint investigation team. The soldiers transferred from the joint investigation team from Star City are stationed here at the city government, so that the inspection and defense at the gate of the city government is even more difficult than other shelters. One level higher, to the point where a fly can't get in, even though there are no flies now.

However, despite the strict screening of entering and leaving the shelter, it is relatively easy and simple to stand at the entrance of the shelter and smoke a cigarette if you don't come out.

Because of the closed interior of the shelter, it is very troublesome to smoke.

After all, smoking in an airtight environment will leave an unpleasant smell if the fumes cannot be dissipated, and smoking in a shelter can easily cause safety hazards such as fire.

So smoking is prohibited inside the shelter, but cigarettes themselves are not prohibited, but if you want to smoke, you need to come to the door of the shelter and smoke in a place with better ventilation.

Considering the pressure of life in the apocalyptic environment and the fact that there are more people addicted to smoking, each shelter has designated a small area at the entrance as a smoking area.

The so-called smoking place is nothing but a corner affected by the wind. Although there is no cold wind to roll up the snow and ice and slap it on the face, standing smoking a cigarette is basically the limit. Standing in such a place for a long time Now, the two feet are not lost consciousness, but will 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 cigarettes are very expensive and need to spend a lot of food and materials to exchange for the black market, or have enough contributions And work points, you can get a very rare package from the materials distributed by the shelter every month.

The same is true for officials who have just finished a meeting in the city hall, especially the boring and mental exhaustion brought about by a long meeting, a cigarette can indeed have a refreshing effect.

Although they are not lacking in cigarettes as managers, they still have to follow the regulations to come to the smoking area at the door.

Because the smoking area is located inside the checkpoint at the entrance, the police and armed police in charge of the inspection just glanced here and paid little attention, and it is even less likely for the staff to offend their superiors.

As a result, there were a few more smokers standing and smoking at the entrance of the municipal shelter.

"Fortunately, I still have a cigarette here, otherwise people can't stand this continuous meeting." It was a slightly wealthy official who spoke with a little Xingcheng accent, indicating that he came from status in the provincial government.

A city official next to him who was also smoking couldn't help but echoed: "Who said no! In this environment, it's a blessing to have a few cigarettes to smoke, otherwise people can't bear it if they get addicted to cigarettes. ."

Several officials came out to smoke during the break in the meeting, and at this time, everyone didn't care about their identity or the difference between the provincial government and the city government, and a few people were chatting about cigarettes. topic of.

However, a cigarette does not burn for a long time, and the rest period in the middle of the meeting is also not long. Soon a few people finished smoking their cigarettes and prepared to avoid the inside of the refuge to continue the meeting.

Only one of them was left behind and didn't seem to want to go in yet.

This behavior naturally caught the attention of others, and one of the officials asked, "Secretary Li, are you still going in?"

"I'll go in after I finish smoking this cigarette." The person who was shouted raised his half-smoking cigarette and smiled.

The person who asked him naturally understands it very well. Now, unlike before, a cigarette is very precious. Naturally, it is necessary to finish smoking it, and it is impossible to put it out after half of it.

Other officials didn't ask much. A group of people who had finished smoking returned to the shelter one after another, leaving only Secretary Li who was still smoking.

However, the time for half a cigarette is very short. When the others are almost gone, Secretary Li's cigarette is almost exhausted.

He finished his last two puffs and threw the cigarette **** into the trash can beside him.

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 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 over to clean, he nodded politely as a greeting.

The cleaning staff also greeted Secretary Li politely. After he passed, he came to the smoking place where a bunch of officials smoked just now, swept the cigarette butts on the floor, and emptied the trash can into his own in the bag.

There's nothing suspicious about this, so the police and armed police at the door didn't pay attention to this side. They paid more attention to 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, 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 rubbish.

In Chen Xin's refuge, Chen Xin quickly drew the design of snow track wheels.

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 chain on the bottom of the car and a fixed rod on the hub to increase the fixed point. The clips together fix the snow track wheel to the wheel so that it will not slip off.

As for removing it when it is not needed, it is easy to remove it, just unfasten the fixing rod on the hub and the chain on the bottom of the vehicle, 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 trivial matters.

The next question is of course how to make this thing. Parts processing is naturally not a problem. With the existence of the system, Chen Xin can easily obtain the parts he wants, but he can't make the track belt without the 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 material from Southeast Asia or chemical rubber obtained through petrochemical technology, it was very easy to obtain before the disaster.

Unfortunately, it is a bit difficult to obtain rubber now after the disaster.

In addition to the rubber raw materials that survived before the disaster, it is estimated that there should be no natural rubber. After all, even if those rubber trees are not burnt, now that the world has entered an ice age, those rubber trees have also lost their growth environment~IndoMTL.com~More No one goes to tap the glue.

On the contrary, chemical rubber should still 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 go in this environment. A planting greenhouse has been specially built to grow rubber.

According to Chen Xin's estimation, the country should have retained some industrial facilities and oil wells before the disaster. With these preserved industrial facilities, production should have resumed after this short half-year.

It's just that now all traffic is in a state of semi-cutoff, only railway transportation can go, and the entire road network is almost paralyzed. Even if rubber is produced, it will be shipped to the places where it is most needed, instead of Waste precious production capacity and transportation capacity to this non-key industrial 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 the fire, and it is difficult to count the unknown number of equipment that can survive. .

After all, the chemical plant itself is a flammable and explosive place. For Chen Xin, who grew up in a chemical plant since he was a child, it can be said to be familiar.

Therefore, there is almost no industrial base in this city. Only the factory area under the municipal government can produce some materials needed by various shelters, and these productions do not say that there is no chemical rubber, and even if there is, Chen Xin can not get it.

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 to extract rubber that can be used as raw materials.

And the most suitable rubber products are naturally tires.
