A month can change a lot of things.

Sun Cheng stood on top of the cliff thousands of meters high on the side of Mariner's Canyon, and under the super vision of the Decepticons, even though the canyon below him was more than 5,000 meters deep, Sun Cheng could still clearly see everything in the canyon.

Hundreds of robots of various types are busy in the canyon, and a few sappers are standing on the side to command.

If you look closely, you can even see that in the wide canyon like a great plain, there are already two strange buildings with a radius of hundreds of meters like yurts.

More than a dozen kilometers away from the two superstar yurt buildings that have already been built, there is a third giant yurt under construction.

"The recent storms are becoming more and more frequent, and the wisdom brain predicts that the next Martian monsoon season will be bring, and I hope to build a third factory before the storm arrives!"

A month ago, Sun Cheng had just arrived on Mars.

At that time, because of the beauty of the sky, they did not directly understand the legendary terrifying and abnormal Martian storm at that time.

The good times didn't last long, though.

God obviously doesn't bless just one person forever, and the good weather doesn't last long.

Almost from the fourth day of Sun Cheng's landing on Mars, storms began to blow continuously.

The first few days were relatively small, lasting only an hour or two.

Then the storm began to escalate little by little, and finally one day it lasted for a day and a half like the end of the world.

Because the wind was raging enough, the Mars base was not prepared for a while, and as a result, more than a dozen robots were blown away by the sudden storm.

Although the sappers recovered and repaired most of the missing robots according to the locator, four were still missing.

Today is the first sunny weather in a long time, there is no storm coming, but the two fire-probing satellites have sent very bad information.

According to the current temperature difference, air pressure and other data of Mars, a pseudo-intellectual brain that was brought to Mars from the earth by Sun Cheng and placed in the base judged that a terrifying Martian storm that may last for a week or even more than half a month is coming.

During the storm, it is obvious that the robot has no way to work outdoors, but fortunately, in the previous storm, Adam and Prometheus have thought of many countermeasures.

With reference to some architectural knowledge on the earth, they designed the hemispherical structure in the canyon that resembles a yurt.

The structure is an underground metal mining and smelting plant, and the two giant yurts are located near a vein, 17 kilometers and 39 kilometers away respectively, from the underground caverns that have been converted into Martian bases.

It is a building designed specifically for Martian storms, and although it covers an extremely large area, it is less than a dozen meters high.

The winds are hardly a real threat to this relatively low structure, and the interior of the two giant yurts is made of all-metal.

In addition to the top floor, the giant yurt is surrounded by discarded earth and rocks excavated during the construction process, and a shell nearly two meters thick has been piled up, which can withstand the impact of most storms, and ensure the safety of the sappers and robots inside.

Inside the two giant yurts, each has a mining passage leading to an underground ore vein, and a transportation passage that also connects to the base through the underground.

Of course, the above is still a design plan for the time being.

In the past month, although the entire Mars base has almost more than ninety percent of the sappers and robots of all types, all of them have been put into the construction of three giant yurts.

However, due to the huge amount of work, so far only the ground facilities of two of the giant yurts have been completed.

As for the underground transportation passages that are tens or even tens of kilometers long, the construction of the first giant yurt has only just begun, and the second has not even started.

However, when the storm comes, the sappers and robots will not be able to go out to work.

At that time, on the Mars base, all the robots will be concentrated to excavate the underground transportation channel.

It is believed that it will not be long before the underground passage will be successfully completed.

In the construction and development of Mars bases, the most scarce resources are not various rare metals and rare earths, but water.

Water is a strategic resource necessary for industry, and this is important not only for humans, but also for the Cybertrons.

So far, Sun Cheng and his team have not found groundwater resources on Mars, but they have found glacial areas and a small amount of solid ice.

Unfortunately, they found that the nearest area of solid ice was more than 780 kilometers away from the Martian base, and it could not be used until a large transporter was built.

However, this does not affect the Martian base to get on the right track little by little, because Cybertron is a metal planet, although there were rivers, lakes, and oceans on the planet in the early days, but with the civil war that lasted for millions of years, coupled with the destructive exploitation of the resources in the occupied area by the Decepticon Legion, water resources could not be obtained from nature as early as the early stage of the second civil war.

To this end, scientists from both the Autobots and the Decepticons have developed a series of synthetic and water-generating methods to sustain industrial use.

For example, the current Mars base, because it is not yet on the right track, and all kinds of machinery and equipment are also insufficient, for the time being, we can only use chemical synthesis and temperature difference to synthesize water resources.

Although the water resources of the Martian base are not yet able to meet the needs of industry.

But because the Decepticons and robots are not carbon-based life that cannot survive without water, they can still endure it.

Anyway, as the Martian base continues to grow, it won't take long for the snowball effect to roll in.

Although the natural environment here is not as fast as that of Earth, the initial development speed of the Mars base is certainly not comparable to that of the second base when it was first established in South America.

But after all, this is a planet that has not been visited by outsiders, and only Sun Cheng is currently eyeing and developing.

It is believed that as more and more Decepticon engineers and sappers are cultivated, and more robots are manufactured, the development speed here on Mars will only get faster and faster, and sooner or later the Earth side that has begun to be constrained by various constraints will be thrown far away.

So, more than a month has passed in the blink of an eye. I don't know what's going on on the other side of the planet now? Shouldn't I go back? ”

Looking up at the sky, Sun Cheng began to remember the other side of the earth in his heart again.

Before participating in the first flight test of the Hope test spacecraft, he had already informed the Precursor and several other subordinates that he would immediately notify himself of uncontrollable dangers on Earth.

Judging from the fact that none of the Forerunners have sent interstellar communications to them in the past month, the Earth should still be safe.

But to say that he is not worried, it is naturally impossible.

After thinking about it for a while, Sun Cheng finally made a decision.

"It's time to go back!"

But before that, he's going to do another little experiment.

……

ps：

There is something temporary, and I arrived home at almost five o'clock, so today I tried to see if I could do three more.
