Doomsday Bunker Upgrade

A set of snow track wheels was soon completed and placed on Chen Xin's workbench.

Looking at the four snow crawler wheels that were made, Chen Xin didn't say anything yet, but Ding Ning and Li Yulong on the side were already eager to try.

"Brother Chen, how about taking it out and trying it? This thing has been made, so you have to try it out, right?" Li Yulong asked Chen Xin tentatively with a little expectation.

Chen Xin thought for a while, then nodded and said, "It's alright to try it, and see if there is any room for improvement. Just try it with my car."

Seeing Chen Xin's agreement, Ding Ning and Li Yulong couldn't wait to run towards the door of the shelter by themselves holding two snow crawler wheels.

Watching the two run up, Chen Xin and Qin Lan glanced at each other, couldn't help but smile at each other, and then walked up together.

The installation of the snow crawler wheel is very simple, you only need to put it on the ground, put on two boards, then drive the car up, and use the weight of the wheel to clamp the wheel into the groove on the snow crawler wheel to complete the installation.

Therefore, it didn't take long for the four snow crawler wheels that had just been made to be installed on the wheels of Chen Xin's car.

Since he agreed to try out the new equipment, Chen Xin didn't talk nonsense, and asked Ding Ning and Qin Lan to change into the protective equipment for going out. He also put on protective clothing in the preparation room, put a pistol in his pocket, and took The breathing mask opened the door of the shelter, got into the car, and was about to drive out.

Qin Lan sat in the co-pilot's seat, while Ding Ning and Li Yulong squeezed together in the back seat.

Seeing that everyone had fastened their seat belts, Chen Xin started the car and drove towards the door of the shelter.

The snow at the door had already collapsed partly because of Li Yulong's subordinates carrying supplies, and this just provided a ramp for Chen Xin's car to go out.

If it is a car without snow crawler wheels, facing the snow that is nearly half a meter deep at the door, even if there is a ramp that has basically been stepped on, it is not easy to go up.

But with snow track wheels, that's all different.

Because the snow track wheels are installed on the wheels, the original chassis of Chen Xin's car has been raised a lot, which undoubtedly increases the vehicle's ability to pass through rough roads or roads that are easy to sink in like snow. ability.

The baffles installed in front of the snow track wheels can help the wheels press the snow surface well without sinking directly.

With the rotation of the wheels, the tracks were driven, and the front of the whole car was lifted suddenly, and it rode up the snow slope, and then drove out with the high-speed operation of the engine.

"This climbing performance is good!" Since Li Yulong sells SUVs, he naturally understands cars. When he went uphill just now with three extra people sitting in the car, it was so easy, enough to show this car. climbing ability.

Chen Xin couldn't help but nodded: "The climbing ability of the track is better than that of the tire, the ground contact area is large, the friction force is also greater, and it is not easy to slip."

However, although he drove out the car, Chen Xin did not continue to drive immediately, but parked the car at the door and said to the three people in the car: "Wait for me, I'll go down and check, and by the way, take the shelter from the shelter. Close the door."

With that said, Chen Xin got out of the car, closed the door of the shelter with the remote control, turned on the flashlight, and checked the situation after the snow crawler wheels were installed on the four wheels of his car.

There is no problem with the installation, and the climb just now performed very well, which naturally makes Chen Xin very satisfied.

However, the problem is not without. After all, the snow track wheel is only a modified part, not a complete snow track assembly. There is still a situation of sagging on the snow.

Although the subsidence is not much, only a few centimeters, this still makes Chen Xin realize the problem.

Compared with professional snow crawler components, the grounding area of ​​snow crawler wheels is still not large enough, and subsidence is inevitable.

Of course, compared with tires, the performance of snow track wheels is already very good, and this level of snow subsidence does not have any impact on the use of snow track wheels. It can still run very smoothly, and will The car is firmly supported, and it will not be stuck in the snow and cannot move.

After checking the connecting components and the chain hanging on the bottom of the car, and seeing that there was no problem, Chen Xin returned to the car.

"Axin, is there any problem?" Qin Lan, who was sitting in the co-pilot, asked Chen Xin with concern.

"The track is still not wide enough, and it still sags a bit, but it doesn't affect the use." Chen Xin shook his head and explained the situation to Qin Lan. Then he looked back at the two people in the back seat and asked them: "Since it is said to be a test drive , where do you think it should go?"

"In this environment, it's almost the same wherever you go, right?" Ding Ning felt that there was snow everywhere, and it didn't make any difference where to test the car.

However, Li Yulong had a different opinion. He thought about it and said, "Why don't we drive to the high-speed rail station? It's more open there, so it's better to test the performance, and even if you want to test the rough road, there are mountains between here and the high-speed rail station. , climbing a mountain is the best test."

"Where is the high-speed rail station?" Chen Xin hesitated for a moment, seeing Qin Lan's expression of approval, so he didn't say anything more, stepped on the accelerator, and drove the car in the direction of the original high-speed rail station.

From Chen Xin's house to the high-speed rail station, there was originally a road connection. Before it snowed, Chen Xin walked to the vicinity of the high-speed rail station and found a group of survivors.

However, as the temperature dropped and the snow accumulated on the ground, the original road could not be seen clearly for a long time.

Driving on the snow, the snow track wheels ran smoothly and didn't feel anything other than maybe a little louder than just using the tires.

But the feeling of experimenting with a new thing still made Li Yulong and Ding Ning in the back seat novel and excited. What does it feel like to have a car with snow crawler wheels.

Chen Xin didn't care, and after stopping the car, he and Qin Lan switched to the back seat, while Ding Ning and Li Yulong sat in the front.

The two had a rock-paper-scissors showdown to compete for whoever drove first. In the end, Ding Ning won and was able to hold the steering wheel.

Looking at the two people in the front seat laughing, Chen Xin couldn't help shaking his head. If it was before the disaster, such a scene was common, but with the advent of the apocalypse, he hasn't gone out with friends like this for a long time. It's been a while, and I haven't heard such laughter for a long time.

However, although the inside of the car is still very similar to the past, the outside of the car is still icy cold with cold wind and pitch blackness.

Although based on the memory of the past, the statue not far away that has not been completely submerged by snow can judge that this is the station square of the high-speed railway station, but it is obvious that the former station square has been completely buried under the snow. .

Even the original ten-meter-high statue on the side has been damaged, leaving only a little pedestal protruding from the snow and the dilapidated statue.

And the high-speed rail station in the distance can only see a shadow standing in the wind and snow, and this shadow has collapsed in a corner, as if it was caused by a meteorite impact.

The high-speed rail network is an important national transportation network built by the Yan Kingdom after the new century.

It’s just that compared to traditional railways, the high-speed rail network built by the Yan Kingdom is more dependent on daily maintenance and the support of the modern civilization system. support becomes useless.

The operation of high-speed rail is extremely dependent on electricity. After all, the high-speed rail train itself is an electric locomotive, and it cannot run without electricity.

Therefore, the entire high-speed rail network is now only useful for railway tracks and high-speed rail stations. The original electric locomotives do not have enough power to supply the entire high-speed rail grid to make it move, nor do they have enough manpower and material resources to maintain them in today's environment. The entire high-speed rail network.

Chen Xin doesn't know what's going on in other places. Maybe some places will allow one or two high-speed rail lines to operate due to the needs of use and their own good conditions, but obviously the high-speed rail station here in this city has been abandoned.

After all, if you just use the rails, the original old rails are enough, and there is no need to spend more energy and resources to maintain the operation of the high-speed rail station.

In particular, because the high-speed rail station in this city is built on the outskirts of the city, the surrounding residents seldom say it, and there is not enough underground space for renovation, unless a new shelter is built on the spot.

Therefore, for the city government, it is not difficult to make a choice and judgment on the abandonment of the high-speed rail station here.

Looking at the abandoned high-speed rail station outside the car window, Chen Xin couldn't help sighing. He sighed for the high-speed rail network that Yan Kingdom spent a lot of money to build, and also sighed for the prosperity and the collapse of civilization.

Just when Chen Xin sighed, there was a sudden muffled sound in his ear, as if thunder had struck.

This made him quickly wake up from the sadness just now, and looked at the other three people in the car, and Ding Ning, who was driving, also hurriedly stopped the car.

"What happened?" Li Yulong was a little surprised, and hurriedly looked out the car window, hoping to find out what happened.

"Isn't it because the meteorite fell? It's quite common these days. It can be encountered every few days in urban areas. It should be..." Ding Ning was a little optimistic, thinking that it should be the impact sound of the meteorite falling. .

However, before she could finish her words, the second muffled sound came again.

The expressions of Ding Ning and Qin Lan changed. They had obviously already reacted. This was not the sound of a meteorite hitting, but the sound of a bomb exploding.

"It's a bomb!" Ding Ning shouted, and quickly turned his eyes to Qin Lan and Chen Xin in the back seat, and asked, "What should we do?"

"Drive back, don't worry about anything." Chen Xin glanced at Qin Lan and said.
