Just as people are celebrating their New Year and arguing endlessly over population policy, a series of subtle changes have taken place on the living planet next door.

There are three human artificial satellites floating on this planet, monitoring the surface conditions at all times. The reason there are only three satellites is because humans did not carry more artificial satellites when they set off from the earth. For such a long time, these three artificial satellites have not experienced any abnormalities on the surface, so that people have gradually relaxed their vigilance.

Gliese 581g, an unremarkable terrestrial planet. Because its mass is larger than that of the earth, it has a thicker atmosphere, mainly composed of nitrogen, carbon dioxide, water vapor, and a small amount of greenhouse gases such as hydrogen sulfide and methane.

Even if the illumination intensity of the central star is not high, the average temperature on the surface can still reach minus 20 degrees Celsius under the action of the greenhouse effect.

The temperature of minus 20 degrees Celsius is quite comfortable for life. Even the north and south poles of the earth have life tenaciously, not to mention alien creatures that have fully adapted to the environment.

Of course, the data of the average temperature does not explain anything, because the temperature difference between the various regions of this planet is very huge...

Incredibly huge!

Due to the tidal locking of the stars, only one side of Gliese 581g will always face the stars. The light-receiving side is under the long-term sunlight, and the temperature is so hot that even the seawater in the center is almost boiling.

But the other side is the eternal night, which is extremely cold. The temperature is more than 100 degrees below zero, causing all the water to condense into thick ice, forming a permanent ice cover with a thickness of several kilometers.

This scene of two heavens of ice and fire has formed an astronomical spectacle that makes people talk about it.

But there's more to the planet's landscape. According to the laws of thermodynamics, heat transfers spontaneously from high-temperature regions to low-temperature regions. The huge temperature difference between the two heavens of ice and fire has caused the air convection phenomenon of the entire planet to be extremely violent.

Heat and water vapor from seawater transfer spontaneously from the warmer side to the colder side, creating gigantic gusts of wind.

Water vapor condenses to form rain. Most of the rain will return to the ocean due to the high level of ice on the shady side. In this way, the water cycle of the entire planet is formed.

Global large-scale air convection has made typhoons of magnitude 15 and 6 common. Sometimes, these violent hurricanes can reach magnitude 18 or even magnitude 20!

In order to adapt to this windy environment, almost all animals on this planet have the ability to dig holes with one hand. When the wind blows, if you don't hide in the hole, you will lose your chance of survival.

In addition, the oxygen content of this planet is very low, and the energy generated by anaerobic respiration is not much. Most of the animals are very short and crawl on the ground, which is somewhat similar to the reptiles on the earth.

Such a living body would crawl out of the ground to look for food only when needed.

All in all, the dusk line is still the best living area on this planet. The temperature here is suitable, the precipitation is abundant, and there is a certain amount of light. As long as you can avoid the huge typhoon, life can live well here...

Of course, the messy hurricane also caused a huge hindrance to the entire human scientific expedition. With the current productivity of human beings, if the scientific expedition team members are put down directly, it is estimated that there will be no return...

Send some drones or survey vehicles to conduct on-the-spot investigations, and they will be blown away by the hurricane within a few days, and then smashed heavily on the ground and scrapped.

For poor human beings, every scientific instrument is precious. In the current situation where there is no way to mass-produce it, if one is damaged, there will be one less. So, until now, human beings still don't know the specific situation on the surface, so they can only use satellites to watch and monitor from a distance in the sky...

After all, life means opportunities, but also...crisis!

On this day, the wind was sunny and cloudless, a rare good weather. The eternal sun hangs in the west and never sets.

A living body like a guinea pig emerged from the ground. It vigilantly observed its surroundings, sniffing here and there, and sensitively made movements of searching for food.

Those yellow and purple dwarf plants with short leaves and extremely developed root system are called "Aruba" by the Gliese people. In ancient times, it used to be a kind of food with little taste, but also a raw material for clothes...

This guinea pig approaches an 'Aruba' before looking up towards the sky.

It is no ordinary creature, but a mechanical mouse!

Powerful electronic eyes began to observe satellites as far as 330,000 kilometers away.

The Earth Age is docked there, a huge spaceship, and a large number of machines are moving back and forth on the surface of the planet...

The mechanical mouse recorded all the data.

Yes, this galaxy does have intelligent life!

Even, and the strength of science and technology far exceeds human estimation.

But fortunately, just like the ultimate prediction of the history of new civilizations, the vast majority of civilizations in the universe are mediocre. The Gliese civilization is also in an unprecedented and irreparable recession...

"Sir, this is the astronomical data we captured, please have a look!"

A Gliese man with a height of only one meter is crawling respectfully on the ground. This is their unique etiquette culture of respect.

Because of the structure of the body, these intelligent creatures do not need stools, nor do they need beds. I habitually squat on the ground when I rest, and curl up my whole body when I sleep.

According to human aesthetics, they look a bit like pangolins, with scales growing on their yellow skin, and their two front paws are flexible and powerful. It looks like a species that is good at digging holes.

Of course, as far as the current level of technology is concerned, they no longer need to use their claws to dig holes. In order to better perform complex tasks, their nails are usually trimmed off.

The officer worriedly flipped through the astronomical report, photos one after another, huge spaceships, and various transportation devices that appeared on the surface. Not particularly clear, but enough.

Everything shows that this foreign civilization is not a scientific research, but to take root here!

Several other Gliese people are discussing in this small room underground: "According to our analysis, it is very likely that the civilization that sent a signal more than 3,000 years ago originated from the solar system and is more than 20 miles away from us." light-year position."

"They've been sending signals ... and we haven't responded."

"It seems to be called...human!"
