Chapter 215: People on the way

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

Although the tracked chassis has many advantages and is more suitable for snow

travel, the biggest problem with the track compared to the wheels 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. Chen Xin cannot easily turn

it on. 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 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 15 kilometers per hour. , And this is just the speed of the car, not the

speed at which he travels 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. Chen Xin

can only determine his own by checking the map. Location, while waiting for

the drone and radar to scan the surrounding road conditions, then decide how

to move forward.

Sometimes it is obvious that the straight line is only 100 meters, but because

there is a big crater hit by a meteorite in the middle of the road, if you

want to go around, you have to walk a few hundred meters, and this winding

will naturally take a lot of time.

So it seems that the speed of 15 kilometers per hour, in fact, it is very

difficult to be able to advance 10 kilometers in an hour on the map.

"Is there another crater? How many are these?" Chen Xin couldn't help but

complain. After scanning by radar and drone, there was another crater with a

diameter of more than 50 meters on the road ahead. , Forcing him to detour.

Although the off-road performance of the track is good, it is not impossible

to go straight down to climb the pit, but if there is a flat road, Chen Xin

still does not want to climb the pit.

During this section of the road, Chen Xin has not allowed the operating system

to drive automatically. Instead, he is holding the steering wheel and

proceeding carefully.

Although autonomous driving saves trouble, the intelligence level of the

operating system installed on the car by Chen Xin is not high enough. The

recognition of road conditions and route planning is only that the car can

pass. So yesterday, when Chen Xin let it drive automatically, he rushed in

several times. 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 uncomfortable.

If possible, he would rather take a little more detour and go as flat as

possible.

But when it comes to craters, when I’m at home, I don’t feel that although

there are houses destroyed by meteorites in the city, craters are not too

common.

However, after coming out, Chen Xin found that there were still many craters

on the road. On average, he could meet one crater after walking for about an

hour or two.

Most of these craters range in diameter from tens of meters to hundreds of

meters, 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 crush the meteorite, it also blasted a lot of debris.

These debris did not directly fall on 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

always float in low-Earth orbit. After the debris that falls on the blue

star's surface is burned by the atmosphere, most of them are in the sky.

Burned out.

Even if the debris that can fall to the surface is not large, the crater

caused by the fall is only this kind of "small crater" of tens to hundreds of

meters.

In fact, since the meteorite hit the blue star, the dust formed by the

meteorite impact in the sky has been falling continuously for more than half a

year. Although it is still pitch black now, no trace of sunlight can pass

through, but with With the passage of time, more and more dust will fall, and

sunlight will eventually penetrate the clouds.

It's just that this time may be very long, and the surface can only recover to

the low-light environment in a short time, instead of the current non-light

environment.

If the earth's surface can be restored to the low-light environment, then the

current human existence should be improved?

Chen Xin controlled the steering wheel. After bypassing the crater, he

switched to the autopilot mode again, and he thought about this problem

himself.

Sunlight is extremely important to human beings and life on the surface. It

can be said that there is sunlight to have life.

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 will not cause the extinction of life.

But without sunlight, most life cannot survive.

Therefore, if the earth's surface can be restored to the low-light

environment, Chen Xin believes that even if the surface is shrouded in low

temperatures of tens of degrees below zero and ice and snow, there will still

be traces of life that will slowly recover.

It's just that this 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 are almost extinct. Even the current period when the

global temperature drops to tens of degrees below zero is not rare, such an

extremely cold climate stage. It is called the ice age by scientists.

There have been two most famous ice ages on Blue Star.

One time occurred in the Pleistocene about 1 million years ago, when humans

had just begun to evolve. Because of the changes in the orbit of the blue star

around the sun, the entire continental edge of the North Atlantic coast was

covered with thick ice.

The other time was about 21,000 years ago, when most areas of North America

and Europe were covered by ice sheets up to 2 kilometers thick, which caused

the sea level to drop by as much as 120 meters. This time the cruelest ice age

in 500 million years has affected at least 30% of the blue star's surface.

However, in these two ice ages, the global ice age events that occurred

between 800 million and 550 million years ago have not been more dramatic and

cruel.

Between about 800 million and 550 million years ago, the surface of the blue

star was completely ice 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 and was dubbed by scientists as a "snowball".

Blue Star".

As for the cause of the formation of the "Snowball Blue Star", there are many

reasons for whether the sun is blocked, or the ice chamber gas is produced in

large quantities, or whether the ice sheet reflects the sun.

Regardless of the cause of the "Snowball Blue Star", the surface of the blue

star at that time was entirely 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 extreme cold weather is not a problem, and

for life, it does not make it completely extinct.

But for humans and other creatures living on the surface of the Blue Star,

this is a natural disaster that can make everything extinct.

Nowadays, the surface of the blue star is rapidly cooled due to the sun being

obscured. In addition, a large amount of surface water has been evaporated by

the previous meteorite impact. Under the influence of the two phases, the

surface has been covered by ice and snow. Very similar.

In such a cold environment, even the ocean has to be frozen. Before the dust

dissipates and the sun shines on the blue star's surface again, the entire

planet is frozen into a snowball.

In other words, even if normal light is restored, the temperature is still

difficult to rise under the reflection of the surface ice and snow. The

extremely cold weather may last for a long time, and this is a long time. It

is based on the blue star itself. .

"This is really unpleasant!" Although it is not different for Chen Xin whether

the extremely cold winter lasts for a hundred years or a million years, it is

still difficult to make people feel good. Reality.

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

Human beings want to see the warmth of spring bloom again, perhaps after a

long time.

Maybe human beings can relive the old days by building a greenhouse, but it

will be a very long wait to see the green mountains, green water, blue sky and

white clouds again.

However, this kind of thing should be the work of a scientist even if it is

considered in depth, and it has no meaning for Chen Xin himself.

Perhaps in the future, he can use the power of the system to create a

planetary transformer to transform the planet's environment, so that the ice

and snow of the Blue Star will melt in advance, and the environment will

return to before the disaster, and even directly transform the Blue Star into

the Gaia planet, but this is all for the future. Up.

For Chen Xin now ~www.mtlnovel.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 mileage is about 150 kilometers, but the straight line travel

distance on the map is less than 40 kilometers, so it can be said that he has

not gone out. How far.

The main reason why he only walked a straight distance of more than 40

kilometers was that Chen Xin encountered the damage of the viaduct on the

high-speed section, and he had to turn back a long way before getting off the

highway and bypassing the damage. Road section.

And this detour has undoubtedly delayed him a lot of time. If there is no

detour, according to Chen Xin's estimation, today he should have walked 10

kilometers in a straight line.

However, in Chen Xin's view, he is not afraid of being slow, just afraid of

not being able to walk.

As long as you can move forward, you will arrive at a slower pace, but if

there is no way forward, that is the most troublesome thing.

He drove the car to a winded depression, parked the car and put down the eight

hoes 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, intending to

give himself make dinner.
