The night cannot affect the vision of the Cybertrons, and the harsh climate of Mars and the low temperature of the night also have little impact on Decepticons like Sun Cheng, Adam, and Prometheus.

"This is the place I chose for my first Mars base!"

Prometheus glanced at the ground in the canyon, and suddenly as if he had made a discovery, he walked over and squatted down and grabbed a handful of fine sand, and two pillars of light shot out of his eyes and scanned for a moment, looking a little excited: "Master, the ordinary soil on Mars also contains a very high proportion of magnesium sulfate, iron oxide, and carbonate, and after proper reaction and refining, we can obtain a variety of minerals in large quantities." ”

Adam picked up a crimson stone and examined it, "What a treasure star!" ”

"A treasure star indeed!"

The smile on Sun Cheng's face couldn't be suppressed, and after looking around the canyon for a moment, he retracted his smile and said in a deep voice: "I can't stay on Mars for too long, so let's get ready to start!" Prometheus, you explore the veins around, Adam and I will go to the cave first, and in a moment I will wake up some of the sappers and let them come and listen to your arrangement!" ”

The news that Sun Cheng has mastered the mysterious space bridge technology and can put a large amount of resources into a mysterious space is no longer a secret inside Base 2.

Because of the legendary space bridge technology, even during the period of the Council of Elders at the peak of Cybertron's civilization, there were only a few in the mastery.

After all, this involves the space field, and even if it is a great Cybertron scientist who has studied in space physics, quantum mechanics and other fields all his life, it is very difficult to get started, let alone the group of Decepticon engineers under Sun Cheng.

So Adam and Prometheus, the two new Decepticon engineers, had only heard some rumors from their predecessors.

Although they were curious about how Sun Cheng hid a huge amount of resources and carried them with him, they had no clue at all.

Prometheus did not dare to question his orders, bowed slightly and agreed: "Everything is as you wish, master!" ”

Sun Cheng then took Adam and walked towards the underground cave hundreds of meters away, like the bloody mouth of a demon hidden in the darkness.

This underground cave is located in the middle of Mariner Canyon, just over 100 kilometers away from the main rift and several bifurcations in the canyon.

In the afternoon, Sun Cheng and the others rode on the Hope test spacecraft and patrolled back and forth in Mariner's Canyon three times before they determined the location.

The average depth of this stretch of Mariner Canyon is about 5.47 km, and the average width is about 267 km.

In this Grand Canyon, which was formed for unknown reasons, Sun Cheng and his team inspected three times in the afternoon and found countless caves and caves.

However, they chose this place because it is located in the middle of the Grand Canyon, and the nearby mountains contain more hematite than other areas.

Not only will it be convenient to mine in the future, but it will also save a lot of trouble by relying on the hard mountain to transform the nearby underground cave that they selected into a base.

Before coming to the cave, Sun Cheng was not in a hurry to enter.

The armor plate on his chest cracked automatically, and a small unmanned reconnaissance vehicle quickly flew out and flew towards the depths of the cavern.

Sun Cheng took Adam with him and walked in without hurry.

Nature's magic is always magical.

Sun Cheng originally felt that the underground cave where he first established Base 2 in Brazil was already a gift from nature.

But compared to this cave on Mars, it is much worse.

The entrance to this cave in the middle of Mariner's Canyon is extremely wide, no less than twenty meters high, and some narrow, only about seven or eight meters, but the cave is extremely deep.

After walking a little further into the cave twenty or thirty meters, you can see a huge rock blocking most of the way.

Adam could easily flip over, but Sun Cheng had to work a little hard.

After passing the roadblock, I walked a short distance and suddenly felt a sense of enlightenment.

An irregular space with a height of no less than sixty or seventy meters and a total area of almost seven or eight thousand square meters appeared in Sun Cheng and Adam's field of vision.

"Yes, it saved us a lot of effort!"

This natural cave alone can save Sun Cheng and them a few days of workload.

Of course, the follow-up will definitely be widened, reinforced, and shockproofed, and in the end, it will even be the same as the main control center of the No. 2 base, and the cave will be covered with high-tech metal everywhere, and you can no longer see the original appearance.

But what does it matter, he wants this base, and it is not for the development of tourism.

Seeing that this space was spacious enough, Sun Cheng thought about it and waved his hand to stop Adam, while he took a few more steps forward and took out the dormant pods of more than a dozen dormant sappers from the spherical space.

"Adam, leave these sappers to you to wake up. One of them will arrange for some of them to go to Prometheus to explore the nearby mineral deposits with him, and sort out more and more detailed information as soon as possible. You'll take the other part with you, and you'll be in charge of designing the cave! ”

"Yes, master!"

Sun Cheng walked to a corner of the cave and took out a batch of engineering robots from the spherical space.

Immediately, he walked deeper along a cave not far away.

This underground cave is much more than expected, and the drone he sent is still transmitting back more information from the cave.

The cave where he and Adam had stayed for a short time had an outward passage to the depths and on each side.

However, two of the holes were too small for Sun Cheng to get through, so he gave up on continuing the expedition to those two sides.

But his drone quickly detected one of the paths, and the results were very encouraging.

Although the entrance and passage of the cave extending to one side are very small, after walking deeper for more than 200 meters, there is a huge karst cave with a length of more than 370 meters, a width of more than 640 meters, and a height of more than 50 meters.

And another passage that Sun Cheng couldn't enter, was soon confirmed by the drone that there was another magic inside, that passage is nearly five kilometers deep, in addition to the small entrance, there are also some caves of different sizes scattered inside, and one of the caves extends down six or seven hundred meters, which is quite wonderful.

On the contrary, it was Sun Cheng, the cave he stepped into alone seemed to be spacious, but in fact, after walking in less than two or three minutes, he saw the end of the passage, there was neither a cave nor other magical places, which made him a little disappointed.

Soon he returned to the same cave again, and looked at Adam, who had begun to wake up the sappers and begin to direct them to busy.

Sun Cheng stepped forward and copied all the information captured by the drone and the three caves he saw and copied it to Adam.

After quickly digesting the information of the cave, Adam looked at the passage that connected the huge space with a total area of more than 200,000 square meters, and ordered the sappers to control the engineering robots and start widening and excavating there.

Sun Cheng's spherical space also stores a large number of materials and robots, and a larger space is needed to place them.

The Decepticons, who had only arrived on Mars for a few hours, immediately began to get busy.
