Doomsday Bunker Upgrade Chapter 213: people on the way

, the fastest update I can upgrade to the latest chapter of the shelter!

Although the crawler-type chassis has many advantages and is more suitable for moving in snow, the biggest problem of the crawler compared to the wheel is that the speed is not fast enough.

In addition, the car itself is heavy enough, and the maximum speed it can run is only 80 kilometers per hour. Even if the engine is overloaded by Chen Xin, twice the electric energy can only make it run to 160. .

The overload mode is used in emergency situations. It is impossible for Chen Xin to turn it on easily. After the overload mode is turned on, it will cause a huge loss to the track, engine, transmission, and even the car body itself, which cannot be sustained at all.

Moreover, the theoretical maximum speed at that time can only be achieved by running in a straight line on a flat and unobstructed road. With the current complicated road conditions and poor sight lines, Chen Xin's current speed is only per hour. Fifteen kilometers, and this is only the speed of the car, not the speed of his travel on the map.

After all, in this environment, the original roads are buried under more than one meter of snow, and the surrounding environment has long been completely unrecognizable. It is impossible to follow the original road at all, and Chen Xin can only check the map. Determine your position, and then wait for the drone and radar to scan the surrounding road conditions before deciding how to move forward.

Sometimes the straight line is only 100 meters, but because there is a big crater in the middle of the road, if you want to go around it, you have to walk a few hundred meters, and this detour will naturally take a lot of time.

So it looks like a speed of 15 kilometers per hour, but in fact it is very rare to be able to travel 10 kilometers per hour on the map.

"Is there another crater? Which are the first ones I encountered today?" Chen Xin couldn't help but complain. After scanning by radar and drone, there was another crater over fifty meters in diameter on the road ahead. The meteor crater forced him to take a detour.

Although it is said that the off-road performance of the track is good, it is not impossible to drive directly down the pit, but if there is a flat road, Chen Xin still does not want to climb the pit.

This section of the road, Chen Xin has not let the operating system to drive automatically, but is holding the steering wheel and moving forward carefully.

Although automatic driving saves trouble, the intelligence level of the operating system installed by Chen Xin on the car is not high enough. The recognition of road conditions and route planning are only the car can pass. So yesterday, when Chen Xin let it drive automatically, It crashed into the crater on the road.

Although relying on the climbing performance of the vehicle itself, these craters cannot hinder Chen Xin's progress after being covered by snow, but for Chen Xin sitting in the car, the bumps caused by the vehicle climbing the crater are too human distressed.

If he could, he would rather detour a little more and walk as flat as possible.

But when it comes to craters, I don't think at home that although there are houses destroyed by meteorites in the urban area, craters are not too common.

But after coming out, Chen Xin found that there are still quite a few craters on the road. On average, he can encounter a crater after walking for about an hour or two.

Most of these craters are tens to hundreds of meters in diameter, and most of them are formed by falling meteorite debris.

In order to prevent the meteorite from falling to the Blue Star, Lucia guided the nuclear bomb launched by Wuchang to bombard the meteorite. Although it did not completely smash the meteorite, it also knocked down a lot of debris.

These debris did not fall directly to the surface of the blue star, but temporarily floated in low-Earth orbit, just like the space junk around the blue star.

Some of them will gradually fall to the surface over time, and some will float forever in low-Earth orbit, and most of the debris that falls on the blue star’s surface is burned by the atmosphere. It burned up in the sky.

Even the debris that can fall to the surface is not large, and the craters caused by the fall are only "small craters" of about tens of meters to hundreds of meters.

In fact, since the meteorite hit the Blue Star, for the past half a year, the dust formed by the meteorite impact has been falling continuously. But over time, as more and more dust falls, sunlight will eventually penetrate the clouds.

It's just that this time may be very long, and the surface of the earth can only recover to a low-light environment in a short period of time, rather than the current non-light environment.

If the earth's surface can be restored to a low-light environment, then the living conditions of human beings should be improved, right?

Chen Xin took control of the steering wheel, and after circumventing the crater, he switched to autopilot mode again, and he thought about it himself.

Sunshine is extremely important for human beings and life on the surface. It can be said that there is life without sunlight.

Compared with the cold, the lack of sunlight is the biggest problem. After all, in the past on the Blue Star, there was no shortage of winter temperatures as low as minus 60 or 70 degrees, but even in cold Siberia, there are Dense forests exist, so the cold doesn't kill life.

But without sunlight, most life would not survive.

So if the surface can be restored to a low-light environment, Chen Xin believes that even if the surface is covered by low temperatures of minus tens of degrees and ice and snow, there will still be traces of life slowly recovering.

It's just that the recovery process will be very long, long enough to use a hundred years as a unit of calculation.

In the history of Blue Star, it is not uncommon for the entire ecosystem to be destroyed and species almost extinct. Even now, the period when the global temperature drops to tens of degrees below zero is not rare. The cold climate stage is called the ice age by scientists.

The two most famous ice ages have occurred on the Blue Star.

Once occurred in the Pleistocene about 1 million years ago, when humans had just begun to evolve, because the blue star's orbit around the sun changed, and the entire continental edge of the North Atlantic coast was covered with a thick layer of ice.

The other time around 21,000 years ago, much of North America and Europe was covered with ice up to 2 kilometers thick and caused sea levels to drop by as much as 120 meters, the most brutal ice age in 500 million years Affects at least 30% of the blue star's surface.

But neither of these two ice ages was more dramatic and cruel than the global ice age events that occurred between 800 million and 550 million years ago.

Between about 800 million and 550 million years ago, the surface of the blue star was completely frozen from the poles to the equator, and only a small amount of liquid water remained on the bottom of the sea. At that time, the entire blue star was completely frozen, which was dubbed by scientists. "Snowball Blue Star".

As for the reason for the formation of the "Snowball Blue Star", there are many reasons, whether the sunlight is blocked by the reverse, or the large amount of gas in the ice chamber is produced, or the ice sheet reflects the sunlight.

Regardless of the cause of the "Snowball Blue Star", the surface of the blue star at that time was covered by a thick layer of ice. Only the ice layer in the equatorial region was slightly thinner, perhaps only a few meters thick.

So for the Blue Star itself, the extremely cold climate is not a problem, and for life, this does not make it completely extinct.

It's just that for humans and other creatures living on the surface of the blue star, this is a natural disaster that can wipe out everything.

Nowadays, the surface of the blue star has been rapidly cooled due to the shading of sunlight. In addition, a large amount of surface water has been evaporated by the meteorite impact. Under the influence of the two phases, the surface has been covered by ice and snow. The star environment is already very similar.

In such a cold environment, even the oceans are frozen, and before the dust clears and the sun shines again on the surface of the blue star, the entire planet is frozen into a snowball.

In other words, even if the normal light is restored, it is still difficult for the temperature to rise under the reflection of the ice and snow on the surface. The extremely cold weather may last for a long time, and this is very long because of the blue star itself. for reference.

"This is really unhappy!" Although it makes no difference to Chen Xin whether the extremely cold winter lasts for a hundred years or a million years, it is still a difficult What a reality of good mood.

The long night may pass quickly, but the cold will not.

Humans want to see the spring flowers bloom again, maybe it will be a long time later.

Perhaps human beings can relive the old days by building greenhouses, but it will be a very long wait to see green mountains, green waters, blue sky and white clouds again.

However, even if you think deeply about such things, it should be the work of scientists, but for Chen Xin himself, it has no meaning.

Perhaps in the future he can use the power of the system to create a planetary transformer to transform the planetary environment, so that the blue star’s ice and snow will melt in advance, and the environment will return to before the disaster, and even directly transform the blue star into the planet Gaia, but this is all things to come.

For the current Chen Xin ~IndoMTL.com~ it is more practical to think about where to rest at night.

I glanced at the map on the console and the records on the display. Today, Chen Xin's driving mileage is about 150 kilometers, but the straight line moving distance on the map is less than 40 kilometers. It can be said that It didn't go very far.

The main reason why he only walked a straight distance of more than 40 kilometers is that Chen Xin encountered the damage of the viaduct on the high-speed section, which made him have to turn back a long way before getting off the highway and bypassing damaged road.

And this detour will undoubtedly delay him a lot of time. If there is no detour, according to Chen Xin's estimation, he should have walked ten kilometers more in a straight line today.

However, in Chen Xin's opinion, not afraid of being slow, but afraid of not being able to walk.

As long as you can move forward, you will get there if you walk slowly, but if the road doesn't work, that's the most troublesome thing.

The car drove to a windy depression, parked the car and put down the eight hoes at the bottom of the car, fixed the chassis and car body as much as possible, and then Chen Xin left the cab and came to the living compartment. Going to make dinner for myself.
