Tang Yue sat on the roof of the Mars Stray Dog Experimental Cabin, looking at the sunset as it dipped below the horizon. In the same direction, the night sky and the starry sky slowly rose.

Tang Yue had heard of the legend of Guixu. In the era when navigation technology and astronomy were not developed enough, the ancients thought that the earth was flat. At the end and edge of the world, there were endless waterfalls and endless seawater flowing from the cliffs.

Pour down and fall into the never-ending void. It is an unimaginably majestic scene.

He tried to imagine Mars as a huge plane. If Mars was flat, then Tang Yue should be able to see the bright Milky Way rising from his feet when he stood on the edge of the earth... It would be great if Mars was flat.

, so that he can look face to face with the universe without having to look up.

It's so painful to raise your neck.

The old cat climbed up from the edge and sat down next to Tang Yue.

One person and one cat sit in a row.

"How far have we come?"

"Ninety-five kilometers."

"How far is it?"

"One hundred and eighty kilometers."

"It's so long... This is really the longest road I have ever walked in my life." Tang Yue said, "What do you think is still supporting me to continue walking?"

"hope?"

"It's not hope." Tang Yue shook his head and whispered, "There is no hope. In fact, you and I both know that this letter is not reliable at all. Even if it is true, I can't win the case. I'm not

Lawyer, the defeat of this battle has long been doomed, and it is impossible for the earth to recover."

"what is that?"

"It's inertia." Tang Yue replied, "People and wheels are actually the same. If you push a wheel forward hard, even if it loses power, it will keep rolling until the energy is exhausted and it falls to the ground.

, I am like this wheel now. I have no power, but I am still rolling forward. When I encounter an obstacle and can no longer roll, I will stop here."

Tang Yue sighed, lay back and faced the sky, and stretched his limbs into a large character.

The old cat also lay down and stretched its limbs into a large letter shape.

"Look at the sky...are those clouds?"

"Yes."

Under the dark night sky, Tang Yue saw extremely thin white flocs, emitting a faint light, moving slowly at a speed that was almost imperceptible to the naked eye.

"Are there clouds here too? It's really rare."

"Of course there are clouds in the atmosphere of Mars... It's just that you don't pay attention to it. After all, there are trace amounts of water and carbon dioxide in the atmosphere. The clouds you see may be ice crystals condensed by water, or they may be dry ice condensed by carbon dioxide, but their

The height is much higher than the clouds on the earth." Lao Mao explained, "It is distributed in the upper atmosphere above 40 kilometers."

Tang Yue looked at the translucent clouds that looked like rotten cotton wool, and suddenly felt that they were like egg whites mixed in Guiling paste.

You can't blame him for not paying attention. The existence of these clouds is so weak that Tang Yue can barely identify them against the dark background at night. These extremely thin clouds float in the atmosphere dozens of kilometers above the ground, reflecting

The sunlight is enough to stand out, but the sunlight is so strong during the day that no one can spot them at all.

Weather changes on Mars tend to be subtle and slow. If there is a weather forecast here, then the weather tonight should turn from sunny to cloudy.

clear.

clear.

clear.

clear.

clear.

clear.

Tang Yue suddenly laughed. He felt that such a weather forecast was inexplicably funny. One word could last ten thousand years.

"It may not always be sunny, there are also storms." Tang Yue suddenly remembered this time. The global storm on Mars lasted for several months and half a year, which was really impressive. "The storm we encountered last time

, you won’t come again, will you?”

"No." Old Mao simply denied, "What we encountered last time was an extremely rare small-scale strong convective weather. There are only a handful of such strong storms in history. The conditions for their formation are very harsh, and the probability is very high.

Winning the lottery is even lower than five million, and you will only encounter it once in your life. If you can encounter it again, you will be the chosen one, and the important task of saving the world belongs to you."

"What about global storms?"

"There is no need to worry about global storms, because they are cyclical and follow rules." The old cat scratched his ears, "Don't be frightened by the word storm. The intensity of global sandstorms in this damn place is actually very low.

It’s not as good as the smog in Beijing.”

Compared with strong convective microclimates that come and go like thunderstorms, global storms are much milder. They usually come slowly and go slowly. I leave gently just as I came gently and wave my sleeves.

, bringing a large swath of smog - like the smog in Beijing when they come.

In front of the Chinese people who are used to all kinds of big battles, a mild Martian sandstorm is really nothing.

"The climate on Mars is very cyclical. To take an extreme example, if a strong wind blows here this year, there may be another similar wind blowing here at the same time and in the same place next year.

Strong winds." The old cat said, "Do you understand? Because global storms are cyclical, we can predict their coming and ending."

“When is the next global storm coming?”

"A global storm will come about once every three to four Martian years, and the next storm will come in the spring after one Martian year, which is two Earth years, or two years at the earliest, so you don't have to worry at all."

The old cat swears by it.

There will be a storm in two years. In Lao Mao's opinion, it will definitely not affect Tang Yue. By that time, Tang Yue has either left or died. They don't care if it floods after they die, even if the strong wind lifts the land.

It doesn't matter, so the old cat can raise the flag as much as he wants, and raise the flag high to Mount Olympus.

Let the whole universe see it!

"But..." Tang Yue hesitated.

"But what?" asked the old cat.

Its flag stands erect and indestructible, and no one can try to pull it out, because standing behind it are Newton, Joule, Pascal and Helmholtz! Predicting storms is essentially a climate issue, and climate issues are essentially a thermal issue.

This is not metaphysics like astrology, but rigorous and accurate physics. Backed by reliable data, Laomao can boldly put flags all over the world!

"But...are you old data from previous observations?" Tang Yue expressed his worries, "After the Earth disappears, won't the orbit of Mars be affected? The heating and circulation conditions of the atmosphere will remain the same as before.

?"

The old cat froze.

Eyeballs bulging.

Holy shit!
