And just like that, it didn't take long for a pile of carapace to pile up under the probe's feet.

It has to be said that the quality of the building materials used by that civilization is still quite good. Even after almost a thousand years, the corrosion of the seawater and the crustaceans attached to the walls did not cause much damage to the building itself. After the carapace was removed, most of the walls were marked white marks, with only a few slight peeling marks on the walls. As more and more carapaces are cleared, the walls in front of the camera are revealing their true faces.

After careful observation, Zhou Xin noticed that there was a slightly protruding rectangle on the flat wall in the picture, and there were some traces of depression in the middle of the rectangle. He soon noticed that Atlas's attention seemed to be focused on the rectangular area, which she hadn't cleaned the surrounding walls after exposing it. Not only that, but when controlling the detector to clean the area inside the rectangle, especially those dents, the little girl's expression was obviously very serious, and if she brought some gravel from the dents during the cleaning, she would even show a look of annoyance.

In this way, a few minutes passed, and when the detector had removed the last piece of carapace from the dent, the little girl on the screen finally showed a relieved look. Then she opened her mouth and said to Zhou Xin: "Brother Captain, if people's judgment is not wrong, I am afraid that these traces are the words used by that civilization." Then her voice looked a little lost, "But because the damage to those towns before was quite severe, even if the original damage was not so severe, most of them have been eroded by the sea and aquatic life for many years. So people don't get much useful information, so it's not so easy to understand what these words mean. ”

While listening to Atlas's introduction, Zhou Xin carefully observed the alien "words" in the picture. As you can see, the number of characters in the rectangular range is not very large, only five. Although the text itself has suffered some obvious damage after the erosion of time and the cleaning of the detector just now, its general appearance can still be distinguished. At the first glance of those words, the first word that appeared in Zhou Xinxin was - wide. That's right, although each word in the picture is the same size, but their width is so wide that it is almost three times their height, and it took only two lines to write just five words.

In addition to being wide, those words also gave Zhou Xin another feeling, that is, "soft". Because almost every word is made up of wavy lines of varying lengths, even some of the diagonal and vertical lines contained in the text have a distinctly wavy shape. Without Atlas's reminder, at first glance, few people would have thought it was text, but it was more likely that it was a painting. In addition to these two distinct features, there may have been other characteristics of those characters, but those features have long been hidden in the erosion of time and cannot be recognized.

"That civilized text—it's a bit peculiar—" Spred said slowly, after a moment.

"Judging from the appearance, the source of these words may be inseparable from water." Zhou Xin answered thoughtfully.

However, Atlas is well aware that since he has not yet figured out the meaning of the "words", it is obvious that relying on the strange appearance of the "words" alone will not attract much attention. So, it didn't take long for her to switch to another nearby probe.

In the newly emerged picture, Zhou Xin recognized it at first glance, this detector, like the detector just now, was moving along a certain street in the city. Slightly different from the previous ones, the buildings on both sides of the street in the picture appear to be significantly more dilapidated, presumably because they are closer to the "coastline". However, what Zhou Xin didn't expect at all was what was hidden in such a dilapidated ruin. As the probe quickly passed through the middle of the street, a large number of disturbed sea creatures swam out of their shelters, and as soon as they appeared, they fled as fast as they could, filling the otherwise lifeless ruins with life.

"Who would have thought that a city that was supposed to be inhabited by a large number of humans would now become a paradise for marine life." Looking at the picture on the screen, Zhou Xin couldn't help but say with emotion, "It's really impermanent. ”

"They were supposed to be able to become a civilization like us." Spred replied regretfully.

As he spoke, the probe came to the end of the street. Here, Zhou Xin and the others rarely saw a city square.

Although the entire city is now overrun by sea life, even this city square is no exception. But in the traces of the activity of sea creatures, it is not difficult for everyone to see the original appearance of the square. Its overall shape is the same as that of the city, with a standard crescent shape. The length of this crescent moon is about 100 meters, and the widest point is around 40 meters. Looking around, the edge of the square is surrounded by a low wall, with only one entrance and exit on each of the two sharp corners of the crescent. Although there are still a few faintly recognizable traces on the ground, these traces have long been unrecognizable in the erosion of time. In the whole square, apart from the low walls around it, the only thing that can be seen is a sculpture-like object standing in the middle.

Sure enough, after glancing at the entire square, Zhou Xin's eyes focused on the "sculpture" in the center. Without his order, the probe quickly aimed there.

As the probe approached the center of the square, Zhou Xin found that after a long period of time, the "statue", like the rest of the city, had a large number of traces of aquatic life on the surface, not only completely unrecognizable, but even looked like a dirty ball of dirt on a pedestal at first glance.

In view of this situation, the probe moved to the "dirt ball" and immediately began to clean it up......
