The closest distance between Mars and the Earth is 54 million kilometers, and the farthest distance is 400 million kilometers.

From Earth to Mars, at Chen Mu's current speed of light, the shortest time from Mars to Earth is six minutes.

Of course, even at a long distance, Chen Mu does not need to spend too much time.

The speed of light is a very terrifying speed.

Normally, it is impossible for something with mass to reach the speed of light. According to Einstein's theory of relativity, the faster the speed, the greater the mass. However, when the mass of an object reaches the speed of light, the mass of the object will become infinite, and there is no such thing as infinite mass in this world.

The reason why light can reach the speed of light is that light does not belong to matter. It does not have a rest mass and belongs to a particle.

Of course, this is a kind of physical knowledge. For Chen Mu, the ability of the system allows him to ignore this physical phenomenon.

"Orange-red Mars."

Chen Mu fluttered his wings and rushed into Mars at the speed of sound.

Chen Mu's speed was too fast, and the friction of the air in the atmosphere of Mars caused a fire to appear in front of Chen Mu.

Chen Mu fell on the ground of Mars like a meteorite, surrounded by flames.

"Boom!"

Because Chen Mu did not control his speed, he fell directly on the ground of Mars like a meteorite.

Accompanied by a loud bang.

A pit suddenly formed on Mars, stirring up a burst of dust.

Chen Mu flapped his wings and flew up, landing next to the pit. He looked around at this Mars.

What he saw was a wasteland.

It looked like a desert on Earth.

Mars is different from the moon. There is basically no atmosphere on the moon, but Mars does. Although the density of Mars' atmosphere is less than one percent of that of the earth, these atmospheres still leave some air.

"System, what is the air of Mars made of?" Chen Mu slowly squatted down, touched a handful of sand from the ground of Mars, and played with it in his hands.

It was cool to the touch.

Chen Mu needed to know what the air on Mars was made of, so that he could know what kind of creatures Mars was suitable for.

On the current Earth, most of the air atmosphere is sulfur dioxide, which is toxic to carbon-based life.

What about Mars?

"The main components of the air on Mars are carbon dioxide, followed by nitrogen and argon, and there are also small amounts of oxygen and water vapor."

When Chen Mu heard the word water vapor, he was startled at first, but then he thought about it and didn't care so much. You know, there was a lot of water vapor on the previous Earth. The water vapor suspended in the air was all water vapor, but it was useless. The water vapor that didn't fall to the ground was equivalent to nothing.

There is still a small amount of oxygen in Mars.

Of course, this extremely small amount of oxygen is not enough to produce life.

Chen Mu opened his hand and looked at the sand in his hand.

"Atomic vision."

He turned on the atomic vision.

After such a long time of understanding the atomic vision, Chen Mu already has a way to judge various substances through the atomic vision.

Chen Mu's eyes fell on the sand in his hand.

In the sand under Chen Mu's feet, in addition to various elements, there is another thing that attracts Chen Mu's attention.

Chen Mu found that there was water on the sand in his hand.

There is water in it, but it cannot be felt by hand, nor can it be seen by consciousness. However, through atomic vision, the various components in the sand can be determined by atoms.

Chen Mu took a glance and roughly found it.

The sand in his hand contains 2% of water.

"There is water on Mars." Chen Mu likes some natural knowledge and has learned about some animals and other things, but it is very one-sided. He knows even less about some astronomical knowledge.

The existence of water on Mars makes Chen Mu interested.

"System, has there been water on Mars before?" Chen Mu asked subconsciously.

"There was water before and there is now." The system gave the answer.

This is not wrong, because there is water in the sand in Chen Mu's hand, although it is very little.

Chen Mu realized that there was something wrong with the question he asked.

He continued, "Let's put it this way. Did Mars have life before?"

"3.8 billion years ago, Mars had life. Later, a large number of meteorites hit Mars, causing ecological extinction. Later, Mars' magnetic field disappeared, and the atmosphere was blown away by the solar wind. After losing the atmosphere, the air escaped, the air density decreased, and gradually became what it is now, a world that cannot breed life." The systematic explanation is like a robot reading a textbook.

3.8 billion years ago, there was a terrifying meteorite impact in the solar system.

The evidence of the meteorite is hard to see on Earth, because the Earth's crust is very active, and some traces have long been buried by various volcanic earthquakes, but the Earth has a follower called the moon. The moon has not had any crustal movement in the past four billion years, and it has carved everything that the Earth has experienced on itself.

In the moon that we can see, we can see countless craters on the surface of the moon, densely packed craters, and by collecting stones in the craters and judging the age of the stones, we know when these craters were formed.

Those craters were basically formed between 3.8 billion and 3.9 billion years ago.

Mars, Earth's neighbor, also has countless craters. It is obvious that Mars, Earth, and the Moon all experienced the same horrific meteorite impact event 3.8 billion and 3.9 billion years ago.

Chen Mu said: "It sounds really complicated... Forget it, I'm not an astronomer, and knowing these things won't help much."

"Let's start building my farm." Chen Mu said: "System, like the Earth, can silicon-based life survive on Mars?"

"No."

"Why?"

"First, the current silicon-based life on Earth breathes sulfur dioxide, and they can use sulfur as energy to replenish their bodies. Mars lacks sulfur."

"Second, the lowest temperature that silicon-based life can withstand is within -100 degrees Celsius, and the lowest temperature on Mars can reach -133 degrees Celsius. Even silicon-based life can't survive on Mars."

Silicon can be made into low-temperature materials. The ultra-low-temperature silica gel that can be made can be used within -100 degrees Celsius.

"Third, Mars lacks a magnetic field and cannot resist the solar wind. The solar wind will directly attack the surface of Mars. At the same time, various high-energy rays in the universe will directly bombard the surface of Mars. Silicon-based life will definitely die in that environment."

Chen Mu fell into silence.

Then what's the point?

This Mars is simply not a place for life to stay.

In other words, this is simply a pasture with no grass? A cemetery?

But this is not a solution.

Chen Mu thought about it, and his mind moved. Some images of steel life that he had seen in the cinema before appeared in his mind.

He said; "Then, how about metal life?"
