It is a very simple thing for Chen Xin, who is already familiar with how to use the system upgrade, to upgrade the car battery to a nuclear battery.

Remove the car battery from your SUV, open the system interface, invest in survival, and click upgrade.

The 1000 survival point disappears and the green light flashes. The car battery made of black-and-white plastic has become a cylindrical nuclear battery with a metal shell shining green.

Looking at this familiar shape, Chen Xin can't help pressing his forehead. Isn't this the battery of Titan in Titan fall?

In the game, this thing is the driving energy of Titan's big guy. It only needs one to make Titan's tall humanoid fighter move, and three batteries can make it gallop freely on the battlefield and play a strong combat effectiveness.

If it's the kind of nuclear battery in the game, it's very suitable to use it in vehicles.

Titan is not only firing guns, but also moving. It also needs to support shields and release all kinds of black technology skills. Nuclear batteries can move, let alone a car.

However, although the nuclear battery was built, Chen Xin still had to check it.

Apart from other things, at least voltage, current and output power still need to be measured to ensure that there will be no problems in use.

After all, if the current is too high, burn the circuit or something, it's not fun.

Fortunately, after some inspection, Chen Xin confirmed that this nuclear battery can continuously produce 300A current at 500V, and the actual power is 150KW, which is about 200 horsepower when converted into horsepower.

This power is already quite large. The batteries used by the popular new energy vehicles before the disaster are basically of this power, but the power stored by those batteries is only about tens of kW · h, which is also an important factor restricting the endurance of new energy vehicles.

But this nuclear cell is different, with long half-life isotopes as the heat source, and its theoretical service life is more than ten years.

Of course, if Chen Xin used to fight on a Titan as in "the fall of the Titan", a nuclear battery would not last long. However, it is obvious that Chen Xin does not need to use it so violently. He just uses it as the power source of the car.

With the output power of 200 horsepower of this nuclear battery, driving an all terrain vehicle naturally has no problem. After all, before the disaster, the engine power of the international classic Swedish bv206 all terrain transport vehicle was only 136 horsepower, only two-thirds of that of this nuclear battery. The weight of the bv206 vehicle was 4.34 tons, and the maximum carrying capacity was two tons.

The weight of an ordinary car is only about one and a half tons, and the output power of this battery is enough for Chen Xin to toss about.

With the most restrictive energy problem solved, the next thing is much simpler.

The chassis Chen Xin of course likes the crawler type, but the body Chen Xin does not want to make a hinged two car like the bv206, but wants to make an integral body.

The advantage of hinged two car is that it is convenient to replace the rear car and realize the switching of different functional modules. At the same time, the hinged connection can also eliminate the torsional load acting on the frame, so it can improve the reliability of the whole structure and greatly reduce the requirements of the vehicle suspension system when the vehicle passes through rough areas.

But what Chen Xin wants is not a carrier car or truck, but a more comfortable RV, which allows him to have a relatively comfortable driving and living environment in the process of driving, not to say that the car bumps like a roller coaster.

Therefore, it naturally has high requirements for vehicle suspension and shock absorption.

What's more, Chen Xin planned to go back to his hometown to pick up his parents. After driving hundreds of kilometers, Chen Xin must consider stopping to have a rest.

If he chooses two hinged carriages, if he wants to use the rear compartment when he stops for a rest, he has to get down from the cab of the front compartment to enter the rear compartment from the outside of the car body. In the current environment, naturally, the danger is greatly enhanced.

The integrated car naturally has no such trouble and danger. It can enter the living cabin of the rear car directly from the cab.

In addition, when he is besieged or at rest, he can enter the cab directly from the living cabin and drive away, instead of having to get off the car and go around to drive.

Therefore, after synthesizing his own needs, Chen Xin decided to transform it into a trailer with tracked chassis and integrated body.

Without the help of the system, it is obviously impossible for Chen Xin to transform his SUV into this kind of thing. First of all, the wheeled chassis will not become a tracked chassis, and the transmission structure and power system need to be redone, not to mention transforming the small body of the SUV into the living cabin of the RV.

But with the system, nothing is a problem.

However, in order to complete the transformation, in addition to the investment of survival, it also needs a lot of materials. After all, without the input of materials, the cost of survival is too high.However, there are quite a lot of materials needed to complete the transformation, even more than the materials needed by Chen Xin to upgrade the refuge as a whole.

Of course, this mostly refers to the type, not the quantity of a single material. After all, the total amount of materials needed to transform a car can't be compared with that of a shelter.

Just looking at the various transformation materials displayed by the system, Chen Xin can't help scratching his head.

Most of the various transformation materials are automobile parts. In addition, there are cold proof materials and materials needed for the transformation of living quarters. Even Chen Xin saw water circulation devices and short wave communication radio stations in the material list.

"To get these things..." Chen Xin copied the material list on the paper, thinking about how to get these things.

Now, no more than before the disaster, it is no longer possible to spend money on these things to solve the problem. It can even be said that many things can no longer be obtained with money, and some even depend on relationships.

It's easy to say about auto parts. Li Yulong used to work as a 4S shop. Chen Xin believes that he can still get auto parts.

As for the cold proof materials and some materials needed for the transformation of the life cabin, Chen Xin found out the list of materials he used when exchanging materials with the special police force, and saw a lot of materials he needed on it.

But the rest, such as water circulation devices, shortwave communication stations Chen Xinyou does, but they are all important facilities installed in the shelter. Is it necessary for him to dismantle the equipment in the shelter in order to rebuild a car?
