Doomsday Bunker Upgrade

The life of others has nothing to do with Chen Xin. What he needs to worry about now is his own life.

The original plan to upgrade the shelter was also affected by this incident. Chen Xin’s original plan to collect materials through Li Yulong’s trading market was temporarily shattered as the trading market and plantations were suspended. The special police team’s material trading was short-term. People don't have this energy anymore.

After all, the trading market project has been suspended, and the SWAT team has to invest its police force in the investigation of this incident, and the material transaction with Chen Xin can only be maintained in the exchange of basic living materials.

This made it impossible for Chen Xin's original plan to upgrade the shelter in a short time.

Although after the ground source heat pump unit of the SWAT team runs smoothly, the survival points have been settled, bringing Chen Xin’s survival point reserve close to five figures, and the daily survival points obtained have exceeded 100. As long as he accumulates for a while, it is enough to use survival points to upgrade the shelter, but Chen Xin still does not want to upgrade in this way.

On the one hand, it is too expensive, on the other hand, a single upgrade plan cannot meet the needs of Chen Xin.

When the survival points of the SWAT team were settled, Chen Xin also discovered that according to the rules set by the system, the upper limit of the survival points he can obtain in a single refuge or settlement is 5000 points, an increase of daily The upper limit of survival points is 50 points.

This obviously limited Chen Xin's idea of ​​quickly acquiring a large number of survival points in a short time, and then using the survival points to directly upgrade the shelter.

Perhaps you can choose an upgrade plan to upgrade first, and then make subsequent adjustments, but if possible, Chen Xin still hopes to upgrade the shelter as a whole in one go.

Therefore, because of the shortage of materials, Chen Xin could only temporarily shelve his refuge upgrade plan and focus on other things.

For example, to upgrade your own car.

In the past few days, because he was going to deliver meals to Qin Lan, he frequently went in and out of the city. As demand for cars increased, Chen Xin also had more requirements for his car, so upgrading and transforming the car became his current goal. Priorities.

However, this is not a big impact. After all, the previous vehicle renovation was the forefront of the various items that he ranked according to the priority. Now it is just the overall upgrade of the shelter. And let this matter become the top priority.

In order to go out before, Chen Xin has upgraded the wheels to improve the capacity of the tires to cope with snowy roads.

But this is only the most basic upgrade, and it will not make a completely different vehicle performance.

Although it is sufficient in this situation, Chen Xin wants more.

The previous changes to the tires only made ordinary snow tires more grippy, and adjusted the chassis height and suspension system, but if you want to continue to improve performance and ride comfort, you must upgrade more things.

For example, the structure of the chassis.

Now Chen Xin's car is still a wheeled chassis, which has the advantages of low fuel consumption, light weight, and good maneuverability, but its traffic capacity is worse than that of a crawler chassis.

Although the tracked chassis is heavier and has higher fuel consumption, it has a stronger carrying capacity and can tow heavier car bodies.

In addition, the driving force of the tracked chassis is greater, and the ground pressure is also smaller, so the off-road performance and stability are good, and the climbing ability is large, and it is more suitable for traffic in the complex road conditions of ups and downs in the wild.

Especially when driving on the snow, the wheeled chassis is prone to tires falling into the snow, while the crawler does not have such troubles. The crawler with a larger ground contact area can make the vehicle run on the snow surface quite smoothly without Cause the wheels to get stuck in the snow.

Therefore, as far as Chen Xin is concerned, he prefers to change the chassis of the SUV in front of him to a crawler type and upgrade it from an SUV to an ATV all-terrain vehicle.

However, the tracked chassis has many benefits, but the energy consumption is a key point that Chen Xin cannot avoid. After all, there is no high-horsepower engine to drive the tracked chassis forward, and high-horsepower also means high fuel consumption.

"So going around, we still have to use nuclear power!" Chen Xin looked at the design sketches drawn by himself on the computer, and felt that he still had to put nuclear power on his car.

Because he counts, only nuclear power can meet his needs. After all, if the tracked chassis is really replaced, the fuel consumption is also very amazing.

As for nuclear power, this is not a high-tech. Although many people talk about nuclear discoloration and directly link nuclear and radiation together, they always feel that this thing is very dangerous, but it has to be said that it is actually based on the current level of human technology. , Nuclear energy can already be used cleanly and efficiently.

Moreover, the continuity and stability of this kind of thing are also very reliable. The nuclear-powered lighthouse built in the pre-Sovia era is still in operation today, only the long-term lack of maintenance and aging of the equipment has radiation leakage.

Therefore, in history, the group of unresolved nuclear bombs not only created nuclear-powered tanks, four-track monsters, but also used nuclear bombs to repair reservoirs and block oil field fires.

And it is not complicated to put nuclear power on vehicles, only a radioisotope thermoelectric generator is needed.

The principle of this kind of thing is to use the radiation with thermal energy released by radioactive materials in the decay process ~ www.ltnovel.com ~ to convert thermal energy into electrical energy in thermoelectric elements.

The radioactive material is very stable during the decay process. The amount and speed of energy released are not affected by the temperature, chemical reaction, pressure, and electromagnetic field in the external environment. Therefore, the radioisotope thermoelectric generator has strong anti-interference and accurate and reliable operation. And famous.

Another feature is that the transformation time is very long, which determines the long-term use of nuclear batteries.

Of course Chen Xin doesn't have a nuclear battery in his hands, and he has nowhere to buy this thing, but having a system means that he can upgrade himself.

If you want to make a nuclear battery, you need to make the long half-life isotope into a charge, and then wrap it with a thermoelectric element. For safety, it may also be wrapped with a layer of lead to prevent radiation leakage.

But the system upgrade is not so troublesome. Chen Xin only needs to prepare long half-life isotopic materials, thermoelectric elements and lead to upgrade the car battery on his SUV to a nuclear battery.

Of course, without these things, there is nothing to upgrade directly with survival points.

After earnestly considering various pros and cons, Chen Xin decided to use the survival point to upgrade a nuclear battery first, and then consider obtaining isotopic materials.

After all, isotope is a controlled material in Yan Country. It is not as easy to handle as thermoelectric elements and lead. He must not be able to get it directly.

But if there is a nuclear battery as a sample, Chen Xin feels that he can make a nuclear battery, he still hopes to get some isotope materials.

Thinking of this, Chen Xin picked up the wrench and screwdriver from the workbench, and decided to remove the car battery from his car and upgrade it to a nuclear battery.
