In this way, since Voyager sent an engineering ship to the planet, more than ten days have passed peacefully. For the first few days, the ship set up a simple workstation on land before it began its first resource gathering on the planet's surface.

Due to the distribution of resources on the planet itself, the location of the workstation was not chosen on the largest island discovered by the probe, but on another narrow island with an area of only 2,000 square kilometers. According to Atlas, the island chosen is a little more "rich" in terms of reserves of various resources. However, this "abundance" is only relative, and in the subsequent process of resource collection, Atlas's previous judgment is well confirmed - it took ten days for the engineering robot to collect resources from the seabed at a depth of nearly 100 meters to fill the entire engineering ship, which is more than half of the slowest speed before. Although Zhou Xin felt a little dissatisfied with such progress, he could only reluctantly choose to accept the reality.

After discovering the dark red asteroid, Atlas studied it with great interest for a while. However, after only a dozen days, she quickly lost interest in it and turned her attention to life on the planet.

When Zhou Xin asked why, she replied: "People also want to continue researching, but the high temperature on the surface of the asteroid at the beginning has destroyed many clues. So far, in addition to being able to determine that the asteroid should have belonged to the core part of a planet, other things such as the size and shape of the original planet, the cause of the rupture, and so on cannot be analyzed at all. In that case, it would be better to put aside the research there for the time being, and wait until the probe collects more clues. At this, the little girl smiled and scratched her head, "Besides, brother captain, don't you think it's much more interesting to study life than to study asteroids." As soon as she finished saying this, she became excited, "Ahhhh Brother Captain, a new species has been discovered on the planet, do you want to take a look? As he spoke, the screen was cut to an aquatic creature with what looked like a flower growing on its back.

Just when Zhou Xin felt a little helpless because of Atlas's move, her voice sounded again, "Oh, by the way, Brother Captain, people have discovered a strange situation during the investigation on the planet in the past few days. Well—it's not particularly strange, it's just that people think it's a little unusual. ”

"What's the situation?" This sentence immediately attracted Zhou Xin's attention.

Atlas's next answer surprised Zhou Xin, "The equipment on the probe has detected radiation everywhere on the planet under our feet—"

"Radiation? How can there be radiation on the planet? Will it affect us? Before Atlas could finish his words, Zhou Xin eagerly asked a series of questions.

"Brother Captain, don't be so nervous." The little girl replied slowly, "The radiation intensity on the surface of the planet is quite weak, and it is no longer even harmful to life. But it stands to reason that even such a faint radiation shouldn't exist on a planet that has been in shape for so long, so people think it's a little strange. ”

Atlas's answer made Zhou Xin breathe a sigh of relief, and then he said casually, "Maybe it's just a special phenomenon on the planet that we don't know about, as long as it doesn't affect us, then don't worry too much." ”

"Hmm." The little girl on the screen nodded, "People are just mentioning it in passing." ”

Within a few days, the engineering ship returned to the ship loaded with the first batch of collected resources.

Looking at the engineering ship on the screen that was carrying out the docking procedure, Zhou Xin opened his mouth and asked, "Voyager, did you encounter any problems in the process of resource collection?" ”

"There are some problems, the first is the efficiency of underwater work, although theoretically engineering robots can work underwater, but from the working conditions these days, the strong water pressure and resistance have seriously affected the work efficiency of the robot. There is also the problem of the reserves of minerals on the planet itself, but this problem seems to have a way to solve, in the process of resource collection, it was found that the deeper the water on the planet, the richer the content of minerals, and the higher the enrichment, so this ship intends to let the robot take the equipment to explore the deeper seabed, I don't know if you agree. ”

"Let's try to send a few robots down to have a look." Zhou Xin commanded, and then he added, "But there should be no problem, I remember that the probes have already reached a position three thousand meters underwater." ”

"Understood."

As Voyager judges, the amount of minerals in the seabed does increase significantly as the depth of the water increases. Considering the impact of water depth on robots and mining equipment, Zhou Xin finally set the mining depth at about 500 meters underwater.

Just when Zhou Xin, who had finished arranging all the work, thought that everything would be on track next, and that he could order to leave as long as the Voyager was repaired, Atlas reported to him a new discovery.

"Brother Captain, Brother Captain." It's still a routine two calls.

"What's wrong?" Zhou Xin asked casually without raising his head, "Have you found any new animals and plants?" "Ever since the little girl began to study life on planets, she would show Zhou Xin some very interesting discoveries every day, and many times even more than once a day, Zhou Xin had already seen it.

"It's not those things this time, it's about the bottom of the sea." Atlas replied.

Hearing this unexpected answer, coupled with the confused tone that Atlas's words showed was completely different from the previous excitement, Zhou Xin's attention was immediately attracted. He put down the task he was working on and looked up at the little girl on the big screen, "Under the sea? What did you find at the bottom of the sea? ”

"When people surveyed the seabed, they found that when the water depth reached about 4,000 meters, there was a clear stratification of the seabed." Atlas first stated her findings, and then she explained, "Generally speaking, because of salinity, the sea does stratify at a certain depth, but it is difficult for the ocean floor to change so significantly at a certain depth. What's more, the phenomenon of seabed stratification that has been discovered has nothing to do with the stratification of seawater. As he spoke, the screen showed the scene taken by the probe at the bottom of the sea......
