However, although in terms of bones, the size of that civilization is generally very high, in comparison, the strength of their bones itself is not high, only about 60% of the earthlings. The internal bone structure is also quite loose, and it can easily break with a little force. Seeing that the attention had been turned back from Spred's, Atlas continued, "Of course, the force they say is according to our standards. Logically, that civilization simply couldn't use the strength that could exceed the strength of their bones. ”

As for why this is so, according to people's estimates, it must have something to do with the fact that the planet's surface is only about 70 percent of the Earth's gravity. Life on the planet doesn't need to use as much force to live on it, so bones don't need to grow as strong, and this is also true for other terrestrial creatures. Based on the same conditions, it can be inferred that the individual size of that civilization must not be very strong, but rather slender. The little girl then explained, "From this condition, together with a large number of skeletal specimens, the general appearance of that civilized individual has been restored. At this point, a model of a humanoid creature appears on the screen.

After carefully observing the model, Zhou Xin found that the humanoid creature in the picture was roughly not much different from the earthlings in appearance. The only difference is their forearms, which have a much larger range of motion than those of earthlings, and can even bend in reverse, looking much more flexible than human arms. Although the calf is not as exaggerated as the arm, the range of motion is not comparable to that of earthlings.

"That's the benefit of low gravity." Atlas clearly knew what Zhou Xin was focused on, explaining, "The structure of the joints doesn't have to be as complex, which gives a lot of flexibility. If the joints of the earthlings or Atlanteans were like those in the model, they would have broken long ago without thinking about exerting force. After explaining this, she added, "Also, because musculature is not something as strong as bones, it can be preserved, especially in seawater for so long." Therefore, it may be difficult for people to restore superficial features such as face and skin. ”

While listening to the little girl's explanation, Zhou Xinzhong was thinking about it, and after a moment of silence, he asked, "Is there a way to confirm the time of their death?" ”

"Based on radiometric dating, it is tentatively concluded that all individuals died about 800 to 900 years ago, which is consistent with our previous inference of sudden extinction." Atlas replied, "Oh, by the way, from what is known so far, individuals of that civilization cannot survive underwater on their own physical condition. So—"

"In other words, if you don't find it on land, there will basically be no survivors left in that civilization, right?" Before the little girl's words were finished, Zhou Xin helped her complete the conclusion, and then he said to himself, "Forget it, if you can't find it, you can't find it, it can only be said that their luck is too bad." The tone of his voice revealed an irrepressible sadness.

Hearing the sadness hidden in Zhou Xin's words, Atlas decisively changed the topic, "Brother Captain, the probe just discovered a new city somewhere at a depth of three hundred meters yesterday. It is tentatively estimated that the city should cover an area of more than 1,500 square kilometers, which is the largest of all the cities that have been discovered. Judging from some of the images observed, it is believed that the city may have been the capital of that civilization or one of the cities of the same level as the capital. As she spoke, she showed the screen the images captured by the probe.

Sure enough, Zhou Xin's attention was immediately attracted by the news, and he looked up at the screen. In the footage, the probe is wandering through an ordinary street in the middle of the city, lined with the remains of collapsed buildings on both sides of the street. Zhou Xin noticed that although the damage to the entire city was still quite severe, the wreckage in the city looked relatively intact compared to the remains of buildings seen in other towns before, and some buildings even preserved the lower half of the building, which had to be a bit surprising.

As if guessing what Zhou Xin was thinking, Atlas explained: "Due to the size of this city compared to other cities on the planet, coupled with the special architectural structure of the city itself. The buildings that were once located along the coast have protected the buildings farther from the sea, so that the buildings in the vicinity have preserved a small half of what we are looking for. ”

As the little girl spoke, the probe approached the wreckage of one of the buildings. Halfway through, the aquatic creatures that had long been accustomed to making their home from the wreckage swam out of the probe. It didn't take long for them to scatter and disappear into the ruins in the distance. Until the probe came to the ruins, Zhou Xindu also saw a slightly sluggish transparent oblongated insect writhing in a panic and swimming away from the crevice in the gravel below.

As the bug disappeared from his field of vision, Zhou Xin focused his gaze on the ruins in front of the camera. It can be seen that due to the time constraints, the walls that should have been smooth were attached to the remains of a large number of aquatic creatures, including the "coral" that had been seen before, as well as the carapace of many unknown creatures. Some of the carapaces are even opening and closing regularly, suggesting that there are creatures hiding inside that are unable to move freely.

Just as Zhou Xin scanned the remnant wall in front of the camera, the detector had already begun its own action. It stretched out its mechanical arm and began to clean the wall of what was attached to it, and as the probe moved, the crustaceans that were still opening and closing closed their shells tightly in the first place, but this did not protect them from the following catastrophe. With just a slight exertion, a lot of mess, including the carapace, fell off the clinging wall and fell to the bottom of the sea, sending up a small puff of smoke.

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