"Captain, look, this is the picture taken by the probe at the location where someone found the anomaly." Atlas said to Zhou Xin while marking the screen, "These photos were taken at a depth of more than 300 meters, and these photos are below 300 meters. After saying this, she stopped and gave Zhou Xin some time to observe carefully.

"It doesn't look any different." After staring at the screen for a few minutes, Zhou Xin still didn't find anything, so he had no choice but to speak.

"Brother Captain, let's see now." Hearing Zhou Xin's words, Atlas removed most of the pictures from the screen, leaving only two of them, and put the remaining two pictures side by side, and then said to Zhou Xin.

The contrast was quite obvious, and it took Zhou Xin less than a minute to see the difference, "It seems that the seabed plants in the picture below are growing more luxuriantly than the one above?" Because he wasn't sure if what he found was the anomaly Atlas was referring to, he couldn't help but speak with an uncertain tone.

"That's really one of those aspects." Atlas replied, "There's a lot more to it than that. Saying that, the little girl released more similar comparison pictures on the screen, which even attached a complete image taken by the probe during the dive, and at the same time, she also explained to Zhou Xin that it was not easy to see the difference, "Brother Captain, look, this is unique to that planet, a creature similar to the polyps on the earth, and they will also accumulate similar structures like coral on the bottom of the sea." The photo below was taken by the probe at a depth of about 310 meters, and you can see that the 'corals' on the seabed are numerous, complex and huge. However, with almost the same vertical position, the water depth is reduced by just less than 100 meters upwards, and the situation on the seabed is completely different. As she spoke, the little girl pointed to another picture on the screen.

Next, without Atlas continuing to explain, Zhou Xin himself can see the difference. Compared to the photo below, the "corals" in the above photo are not only scarce, but also very small, and the shape is very simple, and it looks like it has just formed.

"Of course, this is only possible at the bottom of the sea, where there are 'corals' like this, and the probe has also captured a more common phenomenon." As soon as he finished speaking, Atlas switched to the screen again. However, in the two new photos, Zhou Xin did not see anything other than the bare rocks at the bottom of the sea. Just as he wondered why Atlas had released these two photos, the little girl spoke.

"Brother Captain, pay attention to the erosion of the rocks on the seabed in the two photos." Under Atlas's reminder, Zhou Xin found some clues, and at this time the little girl did not stop, but continued to explain the picture, "At the bottom of the sea below 300 meters in water, the erosion of rocks by seawater is quite obvious, which makes their overall appearance appear relatively rounded. In contrast, this is not the case at the bottom of the sea, above 300 meters, where the edges and corners of most of the stones are so obvious that there are hardly any traces of seawater erosion. In addition, not only erosion, but also the thickness of the sediment on the seafloor has changed significantly at the same depth, and the detector can hardly see much sediment on the seafloor above 300 meters, but the thickness of the sediment can even bury the entire detector if it is a little lower. ”

Speaking of which, the image on the screen froze on the rocks at the bottom of the sea, but Atlas's voice did not stop because of this, "Of course, if this phenomenon only occurs in some parts of the planet, then people may be able to judge that it is caused by the geological activity of the planet itself." However, after summarizing the survey results sent back by probes scattered all over the planet, people can basically conclude that in all places on this planet, there are special faults similar to those in the photos on the bottom of the sea at a depth of about 300 meters, which has to attract our attention. ”

Speaking of this, Atlas stopped, but Zhou Xin did not speak immediately, he looked at the two underwater photos on the screen and fell into deep thought. In fact, not only Zhou Xin, but now most of the people in the command cabin are silently digesting what the little girl just introduced. After synthesizing all the contents, Zhou Xin had a faint guess, and he said in a tentative tone: "Could it be that with a water depth of three hundred meters as the boundary, the seabed on both sides is not formed at the same time——? Is it possible to say that the sea level on this planet has undergone a process of rising? ”

"I'm afraid that's the most likely answer." Atlas replied earnestly, "Moreover, from the extent of the erosion of the sea and the thickness of the sediment, it can be further inferred that the sea level rose no more than a thousand years ago, and it is very likely that it will rise all at once." ”

"How is that possible?" Zhou Xin looked a little unconvinced, "What happened on this planet, how can the sea level change so drastically?" ”

"The exact cause is still under investigation. Some people speculate that it is some kind of special climate upheaval, such as the greenhouse effect. ”

"If it's the greenhouse effect, then the sea level should be rising slowly, and it shouldn't rise so much at once." Regarding Atlas's speculation, Zhou Xin expressed doubts.

"Maybe that's something else." The little girl replied uncertainly.

Zhou Xin thought for a while, and then said, "Finding a way to find out the cause of the sudden rise in water on that planet, if it is some kind of special climate change that we don't know, it will be of great warning significance to us." ”

"What warning significance?" Before the words fell, Spred's voice came from behind Zhou Xin.

"Atlas has made a new discovery on the planet." Zhou Xin casually continued, "For the specific situation, let's talk about it together when Dart comes later." ”

However, the next development of events was completely unexpected by Zhou Xin. Just as Zhou Xin was waiting for Dart while looking through the information that Atlas had investigated, an alarm suddenly sounded in the command cabin for the first time in nearly a month......
