Although the crawler chassis has many advantages and is more suitable for advancing on snow, the biggest problem with crawlers compared to wheels is that they do not move fast enough.
In addition, the car itself is already heavy enough, and the maximum speed it can run is only 80 kilometers per hour. Even if Chen Xin overloads the engine and pumps in twice the electric energy, it can only run to 160 kilometers.
The overload mode is used in emergencies. Chen Xin cannot easily turn it on. Moreover, after the overload mode is turned on, it will cause huge losses to the tracks, engine, transmission device, and even the car body itself, and it will not last long at all.
Moreover, the theoretical maximum speed at that time could only be achieved by running in a straight line on a flat and obstacle-free road. With the current complicated road conditions and poor visibility, the speed Chen Xin maintained now was only fifteen kilometers per hour. , and this is only the speed of the car, not the speed at which it travels on the map.
After all, in this environment, the original road was buried under more than one meter of snow, and the surrounding environment had long been changed beyond recognition. It was impossible to follow the original road. Chen Xin could only check the map to determine his location. Position, while waiting for the drone and radar to scan the surrounding road conditions, and then decide how to move forward.
Sometimes the straight line is only a hundred meters long, but because there is a large crater made by a meteorite in the middle of the road, you have to walk hundreds of meters more to get around it, and this detour will naturally take a lot of time.
So it seems like a speed of fifteen kilometers per hour, but in fact it is very rare to be able to advance ten kilometers in one hour on the map.
"Is there another meteorite crater? How many of these have we encountered today?" Chen Xin couldn't help but complain. Through radar and drone scanning, there was another meteorite crater with a diameter of more than fifty meters on the road ahead. , forcing him to take a detour.
Although the off-road performance of the track is good, it is not impossible to drive directly down to climb pits, but if there is a flat road, Chen Xin still doesn't want to climb pits.
During this section of the road, Chen Xin no longer asked the operating system to drive automatically. Instead, he held the steering wheel and moved forward carefully.
Although autonomous driving is trouble-free, the operating system installed by Chen Xin in the car is not intelligent enough. The recognition of road conditions and route planning are only enough for the car to pass. Therefore, when Chen Xin let it drive autonomously yesterday, he rushed in several times. into the crater on the road.
Although relying on the vehicle's own climbing performance, these craters could not hinder Chen Xin's progress after being covered with snow, but for Chen Xin sitting in the car, the bumps caused by the vehicle climbing the pits were too uncomfortable.
If possible, he would rather take a longer detour and walk on as flat ground as possible.
But when it comes to meteorite craters, I don¡¯t realize it when I¡¯m at home. Although there are houses destroyed by meteorites in urban areas, meteorite craters are not too common.
But after coming out, Chen Xin found that there were quite a lot of craters on the road. On average, he would encounter a crater after walking for about an hour or two.
Most of these craters range from 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 into the Blue Star, Lucia guided the nuclear bomb launched by Wuchang to bombard the meteorite. Although the meteorite was not completely shattered, a lot of debris was blown down.
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 in low-Earth orbit forever. Most of the debris that falls on the surface of the blue star will remain in the sky after being burned by the atmosphere. Burned out.
Even if the debris that can fall to the surface is not large, the only craters caused by the fall are "small craters" of tens to hundreds of meters.
In fact, for more than half a year since the meteorite hit the Blue Star, the dust formed by the meteorite impact has been falling continuously in the sky. Although it is still dark and not a trace of sunlight can penetrate, but as the As time goes by, more and more dust falls, and sunlight will eventually penetrate the clouds.
It¡¯s just that this time may be very long, and the surface of the earth can only return to a low-light environment in a short period of time, rather than the current no-light environment.
If the earth's surface can be restored to a low-light environment, then the living conditions of mankind should be improved, right?
Chen Xin controlled the steering wheel, and after bypassing the crater, he switched to automatic driving mode again, and he himself thought about this problem.
Sunshine, for humans and life on the surface,? is extremely important. It can be said that only with sunshine can there be life.
Compared with the cold, the lack of sunlight is the biggest problem. After all, in the past on Blue Star, there was no shortage of winter temperatures as low as minus sixty or seventy degrees, but even in cold Siberia, there are still dense forests. exists, so cold will not cause the extinction of life.
But without sunlight, most life cannot survive.
So if the surface can return to a low-light environment, Chen Xin believes that even if the surface is shrouded in ice and snow at temperatures as low as tens of degrees below zero, there will still be signs of life that will slowly recover.
It¡¯s just that this recovery process will be very long, long enough to use hundreds of 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 to be almost wiped out. Even the current period when the global temperature drops to dozens of degrees below zero is not uncommon. Such an extremely cold climate stage It is called an ice age by scientists.
There have been two of the most famous ice ages on Blue Star.
The first time 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, the entire continental edge along the North Atlantic coast was covered with thick ice.
The other time was about 21,000 years ago. Most of North America and Europe were covered by ice up to 2 kilometers thick, and caused the sea level to drop by as much as 120 meters. This time, the cruelest ice age in 500 million years at least affected 30% of the blue star's surface.
But these two ice ages were not as dramatic and cruel as the global ice age event 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, with only a small amount of liquid water remaining on the seafloor. At that time, the entire Blue Star was completely frozen, and it was jokingly called a "snowball" by scientists. Blue Star".
As for the reason for the formation of "Snowball Blue Star", there are many reasons: whether the sunlight is blocked, the ice chamber gas is produced in large quantities, or the ice cap reflects the sunlight.
No matter what the cause of the "Snowball Blue Star" is, the surface of the Blue Star at that time was completely covered by a thick layer of ice. Only the ice layer in the equatorial region was slightly thinner, maybe 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.
But for humans and other creatures living on the surface of Blue Star, this is a natural disaster that can wipe out everything.
Nowadays, the surface of the blue star has cooled rapidly due to the blockage of sunlight. In addition, a large amount of surface water has been evaporated by previous meteorite impacts. Under the influence of these two phases, the surface has been covered with ice and snow. This is different from the blue star environment during the "Snowball Blue Star" period. Very similar.
In such a cold environment, even the oceans are frozen. Before the dust disperses and the sunlight shines on the surface of the blue star again, the entire planet has been frozen into a snowball.
In other words, even if normal lighting is restored, the temperature will still be difficult to rise under the reflection of surface ice and snow. The extremely cold weather may last for a long time, and this long time is based on the Blue Star itself. .
"This really makes people 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 time to put people in a good mood. reality.
The long night may pass quickly, but the cold does not.
??It may be a long time before humans can see spring flowers blooming again.
¡°Perhaps humans can relive the past by building greenhouses, but it will be a long wait to see green mountains, green waters, blue skies and white clouds again.
¡°However, even if we think deeply about such things, it should be the work of scientists, but it is meaningless to Chen Xin himself.
Perhaps in the future, he can use the power of the system to create a planet transformer to transform the planet's environment, allowing the ice and snow on Blue Star to melt in advance, returning the environment to before the disaster, or even directly transforming Blue Star into the planet Gaia, but this is all a matter for the future. .
For Chen Xin right now, it is more practical to think about where to rest at night.
After taking a look at the map on the console and the records on the display screen, Chen Xin's driving mileage today was about more than 150 kilometers, but the straight-line distance on the map was less than 40 kilometers. It can be said that he has not traveled far. How far.
The main reason why he only walked a straight line distance of more than 40 kilometers was that Chen Xin encountered a damaged viaduct on the highway section, which forced him to turn back a long way before getting off the highway and bypassing the damaged viaduct. section.
And this detour undoubtedly delayed him a lot of time. If there had been no detour, according to Chen Xin's estimation, he would have walked an extra ten kilometers in a straight line today.
But in Chen Xin¡¯s opinion, the fear of not being slow is the fear of not being able to walk.
As long as you can move forward, you will get there if you go slower, but if the way forward is blocked, that is the most troublesome thing.
He drove the car to a windy depression, stopped the car and put down the eight auxiliary tools at the bottom of the car. After fixing the chassis and body as much as possible, Chen Xin left the cab and came to the living cabin, planning to give himself make dinner.
