Ding Ning got in touch with the city bureau with the help of Chen Xin's shortwave radio station, and informed them of Chen Xin's speculation and concerns, and finally felt a lot more relieved.

Although I don't know how useful my reminder is, it's better to remind than not to come, and it can also make you have a clear conscience.

However, for this matter, there is only so much that Ding Ning and Chen Xin can meddle in.

In the final analysis, both Ding Ning and Chen Xin are just ordinary people, Ding Ning has at most the father of the captain of the SWAT team, and Chen Xin is nothing more than picking up a plug-in in the system.

But Ding Ning's father of the SWAT team also has limited care for her, and it is impossible to mess around for the sake of his daughter, and Uncle Ding does not have that right.

As for Chen Xin, although he is indeed powerful in some aspects with the system, the problem is that he was just an ordinary person before obtaining the system, and the foundation he held in his hands was too weak, so that after having the system, he could not quickly use the system to enhance his own strength.

From the current point of view, the biggest role of the system is to ensure that Chen Xin can live better in today's environment, and it is not yet possible for him to have the ability to interfere in other things.

So after reporting this matter, Ding Ning and Chen Xin did not continue to pay attention to this matter, but simply discussed a few words, Chen Xin went to busy his afternoon work, and Ding Ning also came over to help him.

Chen Xin's vehicle transformation plan is being carried out as scheduled, but at present, because the parts and materials promised by Li Yulong have not been delivered, Chen Xin can do very little.

And Chen Xin, who didn't want to spend more on this car before upgrading, had no intention of upgrading it at this time, so although he said to Ding Ning that he was going to renovate the vehicle, in fact, Chen Xin was just disassembling and inspecting and repairing the car in front of him.

After all, this car is not designed to drive in such a harsh environment, although Chen Xin has not driven many times in the past six months, but the damage to the vehicle by extreme cold and dust is not small, and inspection, repair and maintenance are necessary.

Although Chen Xin has never done vehicle repair and maintenance by himself, it is impossible for him to say that he can drive the car to a 4S shop for maintenance in this kind of world, so he can only get started by himself.

Fortunately, as a car owner, Chen Xin will still be able to judge and eliminate basic faults.

After opening the hood and looking at the engine and other parts that were already covered with dust under the hood, Chen Xin took out a large brush and began to brush the dust on it.

As for other more professional parts failure inspection, Chen Xin can judge which part has a problem with the help of the system's upgrade interface, after all, in the system interface, if there is a fault, it will be displayed as "faulty XXX parts".

However, although the dust accumulation is a bit serious, Chen Xin's car is in good condition and does not show which parts are faulty.

"Ah Xin, how are you going to modify your car?" Ding Ning was on the side planning to help, curious about how Chen Xin planned to transform the car.

There is no fault in Chen Xin's engine compartment, Chen Xin removed the battery and upgraded it to a nuclear battery, but the upgraded nuclear battery is not the same size as the original battery, and the output power is also far away, Chen Xin cannot directly install the nuclear battery as a battery.

Therefore, Chen Xin had to spend another 500 survival points to upgrade the power system of this car, upgrading it from fuel power to electric power, and then installed the nuclear battery back to avoid the dilemma that the car could not catch fire because the battery was removed.

But because Chen Xin didn't want to waste the upgrade point, this upgrade only adjusted the power system, and did not make other changes, and even the dust in the engine compartment was not reduced, it seems that this car has always been like this, and it has been driving for a long time.

Because of the existence of the ambiguous function of the concept of information state, and the battery itself is not inconspicuous, under the cover of dust in the engine compartment, it looks like a dusty part.

For Ding Ning, who doesn't know much about cars, she can't even tell whether this is a fuel car or an electric car, and naturally she can't distinguish the nuclear battery that has been blurred in concept.

"Ah Xin, how are you going to modify your car?" Ding Ning watched Chen Xin cleaning the engine compartment, so he took a few steps back to avoid dust falling on his body.

"At present, I plan to change the wheels to crawler, so that it is more convenient to drive on the snow, and the tires are still too easy to sink into the snow." Chen Xin answered Ding Ning's question while clearing the dust.

According to the standard cleaning process, the engine should be cleaned with a cleaning agent after cleaning the dust inside the engine compartment with a soft brush, but now the conditions are limited, and Chen Xin can only sweep the ash.

Hearing Chen Xin say that he wanted to replace the wheels with tracks, Ding Ning felt a little incredible: "The track chassis and the wheel chassis are completely different things, right?" How can this be transformed? ”

"What's not to be transformed about this? It's a pity that I didn't buy that kind of track modification before the end of the world, otherwise there would be no need for such a modification. Chen Xin closed the engine cover after cleaning up the dust in the engine compartment with a brush, and did not care about Ding Ning's problem.

However, Ding Ning was aroused by Chen Xin's words and asked him: "Track modification?" What's that? ”

"There is something called snow track wheels, which itself is a track structure, and it can be stuck on the wheels through the attachment mechanism, so that the wheels become tracks." Chen Xin explained to Ding Ning that he had only seen that kind of thing on the Internet, and he wanted to buy it at that time, but he didn't see this kind of commodity for sale in Yanguo.

Ding Ning was very interested in this, and pestered Chen Xin to ask him about this kind of snow track wheels: "What kind of thing is that?" Ah Xin: Do you remember the structure? Can you do it yourself? ”

"I remember the structure, but if I want to say that I did it......" Chen Xin was entangled by Ding Ning with a little headache, but still answered her question, but just wanted to say that he couldn't do it, but suddenly paused.

It seems that with the help of the system's workbench, he can make this thing?

First of all, the structure of the snow track wheel is not complicated, it is not like the traditional track system to replace the wheel, so it does not need to modify the transmission of the car or replace the tire, only need to put the snow track wheel on the ground, and then drive the car up, and it can be installed by sticking it on the wheel.

The two do not have power themselves, but rely on the original wheels of the car to drive the track forward, so there is no complex transmission structure, let alone the design of the power system.

Knowing the structure and principle, it is not difficult to make something similar, especially for Chen Xin, who has a system, it is even easier to build it.

Ding Ning looked at Chen Xin and was stunned, so he pushed him: "Ah Xin, what are you doing in a daze?" Can you do this? If you can do it, I feel that the demand is still quite large, and you can exchange supplies with my dad after you do it.

A lot of cars in the bureau are a bit of a nest now, and the snow really can't drive, so it would be great if you could solve this problem! ”

Being pushed by Ding Ning like this, Chen Xin also came back to his senses, nodded at her and said, "I was thinking about the structure of this thing just now, it seems that it can be made if you want to do it, this thing is not complicated." ”

Chen Xin said, and took Ding Ning from the garage back to the workbench in the shelter, took out a blank paper and pencil, and began to sketch.

Since it is called snow track wheels, it must be a track structure, so a track is essential, but there is no need to use metal tracks, rubber tracks are enough.

While recalling the kind of snow track wheels he had seen, Chen Xin sketched on the paper, and Ding Ning also watched with interest, and from time to time asked some curious questions to Chen Xin.

"Ah Xin, how did this thing get stuck on the wheel?" Ding Ning looked at the sketches that Chen Xinxing gradually drew on his hands, and asked him curiously.

Although Chen Xin drew a sketch and a general structure of the snow track wheel, he still did not know much about how it got stuck on the wheel.

After all, he has only seen pictures and videos, not physical objects, so what he draws on paper is only what he recalls by feeling, and he can only know if he actually does it.

However, Chen Xin still replied to Ding Ning by feeling: "It is used under the wheel, so it should be pressed by the weight of the vehicle itself, and it is fixed on both sides of the part connected to the tire, which should also be prepared to prevent it from falling."

I'm not sure if that's the case, because I haven't seen the real thing, and I'm just painting based on impressions, so whether it's good or not may have to be made later, and I can only know if I actually use it. ”

Chen Xin said this, and at the same time, he was constantly improving the design drawing, and at the same time, he was also thinking about how to make things.

This thing is like Ding Ning said, if it can be made, it is indeed in great demand, because it can solve the driving problem of most cars with wheel chassis in today's environment, without having to use a more laborious way to remove the wheels and replace them with tracks.

Although replacing with a track system is a one-and-done option in today's environment, since the underground passage has been repaired in the urban area, many cars still need to use wheels to drive, after all, the wear and tear of the track on the road is far greater than that of tires.

Therefore, this kind of track modification that can be easily disassembled and assembled is far more convenient and practical than the track system that needs to disassemble and assemble the wheels.

It's just that if you are not sure of the specific fixed structure, Chen Xin can only make one first, and then use the system upgrade to determine its fixing method, after all, it is impossible to really fix it as he said, just rely on the weight of the vehicle itself to press on it, so it is easy to fall off if the rugged terrain crosses a ditch or something.
