Doomsday Bunker Upgrade

How other people's lives have nothing to do with Chen Xin, he needs to worry about his own life now.

The original plan to upgrade the shelter was also affected by this incident. Chen Xin's original plan to collect supplies through Li Yulong's trading market was temporarily shattered when the trading market and plantation were stopped. People don't have the energy anymore.

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

This made Chen Xin's original shelter upgrade plan unable to continue in a short period of time.

Although the survival point has been settled after the ground source heat pump unit on the SWAT team runs smoothly, the survival point reserve on Chen Xin's head is close to five figures, and the survival point obtained every day has also exceeded 100. As long as he accumulates for a while, it is enough to upgrade the shelter with survival points, but Chen Xin still does not want to upgrade in this way.

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

When the SWAT team's survival points were settled, Chen Xin also discovered that, according to the rules set by the system, the upper limit of the survival points he could obtain in a single shelter or settlement at one time was 5,000 points. The upper limit of survival points is 50 points.

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

Maybe you can choose an upgrade plan to upgrade first, and then adjust it later, but if possible, Chen Xin still hopes to upgrade the shelter as a whole in one place.

Therefore, due to the shortage of supplies, Chen Xin could only temporarily shelve his shelter upgrade plan and focus his energy on other things.

For example, upgrading your car.

In the past few days, he has been in and out of the city frequently because he is going to deliver meals to Qin Lan. With the increase in the demand for cars, Chen Xin has more requirements for his car, so upgrading and transforming the car has become his current priority. priorities.

However, this is not a big impact. After all, the previous vehicle modification was the top priority among the various items he ranked according to the priority. Now it is just to move the overall upgrade of the shelter backwards. And make this a top priority.

In order to go out, Chen Xin has already upgraded the wheels to improve the ability of the tires to deal with snow roads.

But this is only the most basic upgrade, and does not make the vehicle performance completely reborn.

Although it is enough in the current situation, Chen Xin wants more.

The previous modification to the tires only made ordinary snow tires more grippy, and adjusted the ride 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 the traffic capacity is worse than that of the tracked chassis.

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

In addition, the driving force of the crawler chassis is larger, and the grounding specific pressure is smaller, so the off-road performance and stability are good, the climbing ability is large, and it is more suitable for the passage of complex road conditions with high and low fluctuations in the field.

Especially when driving on snow, the wheeled chassis is prone to tires getting caught in the snow, while the track has no such trouble. The track with a larger ground contact area can make the vehicle run quite smoothly on the snow surface without noticing. Causing the wheels to get stuck in the snow and get trapped.

So for Chen Xin, he prefers to replace the chassis of the SUV in front of him with a crawler, and upgrade it from an SUV to an ATV all-terrain vehicle.

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

"So going around, it's still necessary to use nuclear power!" Chen Xin looked at the design sketches he drew on the computer and felt that he still had to use nuclear power for his car.

Because of his calculations, only nuclear power can meet his needs. After all, if he really replaces the crawler chassis, the consumption of fuel is also very amazing.

As for nuclear power, this is not a high-tech thing. Although many people talk about nuclear discoloration and directly link nuclear and radiation, they always feel that this thing is very dangerous. , it has long been possible to use nuclear energy 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, but the equipment has been lacking maintenance and aging for a long time before the radiation leaks.

Therefore, in history, the group of Maozi who were indecisive and hit a nuclear bomb not only created a four-track monster like a nuclear-powered tank, but also used nuclear bombs to repair reservoirs and block oil field fires.

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

The principle of this kind of thing is to use the radiation with heat energy released by the radioactive material in the process of decay, and convert the heat energy into electricity in the thermoelectric element.

Radioactive substances are very stable in the process of decay, and 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 decay time is very long, which determines that the nuclear battery can be used for a long time.

Of course, Chen Xin doesn't have a nuclear battery on his own, and he has nowhere to buy it, but having a system means he can upgrade it himself.

To make a nuclear battery, the long half-life isotope would be made into a charge, which would then be wrapped with a thermoelectric element, possibly with lead to prevent radiation leakage.

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

Of course, without these things, there is no problem with directly leveling up with Survival Points.

After careful consideration of various pros and cons, Chen Xin decided to directly upgrade a nuclear battery with survival points, and then consider the matter of isotopic materials.

After all, things like isotopes are controlled materials in the Yan Kingdom. They are not as easy to get as thermoelectric elements and lead. He will definitely not be able to get them directly.

But if there is a nuclear battery as a sample and he says he can make a nuclear battery, Chen Xin feels that he still has some hope of getting some isotopic materials.

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