Just after a hard day's work, whether it is going to class, going to work or really working in the fields, what you need is to wash your face with cold water, rinse your mouth, and then drink a big sip of cold water or drink, and then lie comfortably on the sofa or bedside, and after the physical and mental exhaustion has dissipated, stand in front of the window, and quietly wait for the night to come.

Night will not come, the sun is already on the horizon, but it refuses to set for a long time, and always shows the upper part of the earth, and half of the sky is red.

It was past nine o'clock in the evening, but it was still not completely dark outside, and the sky was dark blue, and the sky was red and purple clouds floating in front of the stubborn sun, and the sun refused to leave for a long time, just as the sun never left the wonderful horizon.

Slowly, people finally understood the reason why the sun was motionless in the sky. It turns out that the rotation time of the planet has become the same as the revolution time.

Now, some people are more uncomfortable. The temperature on the side that always faces the sun has reached 40 degrees. The heat was unbearable, and people migrated in droves, running towards the side with the sun on their backs.

At first, the side that always turned away from the sun did not notice anything abnormal, but after more than ten hours, the sky was not yet dawn, and some people thought it strange. I learned from the news on TV that the sun would not come back.

Eternal dark nights are loved by some and annoyed by others. Whatever those people like about the night, is it quiet? Is it a beautiful night light? It's an abnormal night. Those who still want to sleep are no longer able to sleep peacefully. They all walked out into the street and looked at the sky that should have been lit up, but it was still full of stars.

After a while, people felt that the weather was getting colder, and people went back to their houses to get thicker clothes to put on.

The wind began to blow, and the big trees under the lights in the distance had begun to sway with the wind, and it was no longer a big tree that could be shaken by the breeze, it was definitely a strong wind above level five.

The temperature dropped to more than 10 degrees Celsius in a short time, but the people who were already dressed in thick clothes did not realize how cold it was, but felt that the insects that used to chirp loudly at night were silent, and there was silence all around, only the sound of wind and leaves.

Some went back to the house when they couldn't stand the cold, while others were excited, writhing in the dim light on the smoky dance floor. Some restaurants were about to close when they saw a lot of people running by, and it suddenly became a 24-hour bar.

The temperature in the very center of the Hemisphere has dropped to minus forty or fifty degrees Celsius, and it is still decreasing. It had become a real icy place, and the snow was falling half a meter thick, and it was still falling. The people there have moved their families and there are no more people left.

A few hours ago, people were walking on sunny streets in short-sleeved trousers, and the temperature was hovering around 356 degrees, and after a few hours, it became the coldest place, and the temperature difference was unheard of.

On the other hand, the temperature there has reached more than 50 degrees, and some flammable and explosive materials will give you a moment if you are not careful. As a result, there have been hundreds of fires there, and people are simply too busy to put out the fires.

People are much happier in the area where day and night meet, where the temperature is very moderate, the cold is only more than 10 degrees, and the hot is only about 30 degrees.

All the news is reporting on this, people are hurrying to pack their bags, move their families, and go to a place they have never been before, where they can live, where they can see the sun in the sky, look back at the beautiful night sky, take two steps forward and it will be daytime, and a few steps back will be night.

However, it didn't take long for the place where night and day met to be overcrowded. Not only that, but the temperature difference between the two hemispheres surrounding the planet continues to widen, and the pressure difference caused by the temperature difference also widens, resulting in a world-class gale.

Before the new residents could gain a foothold, they were swept away by the gale. The gale was like an incomparably huge broom sweeping across the earth, and those tents that were fastened were swept up to the sky, and those who weighed more than 200 pounds were not enough to see, even if they grabbed the big tree, even the tree took people to the sky together.

After a gale, mountains turn into hills, lakes into swamps, rivers into valleys, and grasslands into deserts.

A gale took away more than a billion people, and those who left late were lucky. If you look up, you can see tents, cars, houses, trees, and so on flying high in the air, and it feels like a god is casting a spell and someone is driving the clouds.

The wind's contents fell on the central part of the eternal day hemisphere, where the fire had been burning for a long time, and now it was like firewood that had brought in new combustibles, and the fire was raging again.

Gale took life away and brought hope for survival. The hot air was sent by the gale to the hemisphere of eternal night, warming the air, the earth, and the hearts of the people. At the same time, the cold air is transported by the strong wind to the hot eternal day hemisphere, which lowers the temperature there and refreshes people's hot hearts.

After the gale, there was another heavy rain.

This heavy rain only visited the hemisphere of eternal night, because the source of the rain was the moisture brought by the hot air. As a result, the eternal night hemisphere is flooded, and the eternal day hemisphere is dry and rainless. People are united in order to survive. The people of the Eternal Night Hemisphere brought water to the Eternal Day Hemisphere, and the plan was implemented in less than half an hour.

After a few days, people have come to terms with the reality that it is dark or day, and it is important that everyone is together to live.

The hemisphere of the eternal night is at minus 50 degrees Celsius, and no one wants to set foot in it again, except for a few dedicated scientists, even if it was once their home. The expansion of the ultra-low temperature area has stopped, and it is basically the cool breeze blowing in the air that stops the spread of the low temperature area. On the other side, the temperature stopped at 59 degrees and no longer rose, but it still could not make people survive, and the size of the ultra-high temperature area was about the same size as the area of the ultra-low temperature area on the other side, occupying a range of about 60 degrees of longitude.

A few months later, some adventurous sports enthusiasts ventured into ultra-low temperatures, and some lesser-known skiing began to flourish. And some people who like to show off their slim and strong bodies began to gather in the sun, on the sand ponds, and some swimming projects also became popular.

A few hundred light-years away from this planet, there is an even bigger planet, and on that planet there is an astronomer who has detected this strange planet through a telescope, measured the data, and published the conclusions in scientific journals for people to see.

The astronomer came to the conclusion that the temperature of the sunny side of the planet is about 560 degrees, and the sunny side is about minus 450 degrees, with a temperature error of 20 degrees, and with the thin atmosphere, there is no life on the planet.

Finish.
