Following Guo Feng's order, the members of the team entered the rover again, and began to dig on the spot using the bucket carried by the rover itself.

After all, this Mars rover has already taken these issues into consideration when designing and manufacturing, so this Mars rover has many functions. There are a variety of manipulators of different sizes, the largest of which can extend to more than 30 meters in length, and can also install a variety of excavation equipment and manipulators. It is definitely one of the best equipment for exploring Mars.

Following Guo Feng's digging, they soon dug down nearly ten meters. Just when they wanted to continue digging, suddenly, a team member saw the situation below through the camera on the top of the robotic arm.

So the team member said: "Captain! Stop for a moment, there seems to be something below."

"What's there!" After finishing speaking, the captain Guo Feng also looked down.

Sure enough, he saw a huge stone standing quietly at the bottom of the tunnel dug out by them. Of course, if it was an ordinary stone, it would not attract their attention, but the one below The stone is obviously not an ordinary stone, but a rectangular stele with very smooth surroundings. The most important thing is that there are some patterns and some words on the stele.

Therefore, from all kinds of evidence, this stone tablet is definitely not formed naturally, but is carved by artificial polishing.

That is to say, from the appearance of this stele, it has been shown that Mars once had the existence of intelligent civilization, because only intelligent civilization can make such a stele, and it still needs to be developed to a certain level when civilization, because even It is a primitive civilization, and it is impossible to create such a stone tablet.

This made everyone in the entire exploration team very excited, and immediately used the manipulator to continue digging down. After all, the exposed part of the stele is only less than 20 centimeters, so there is still a large part below, and Not dug up.

Sure enough, as they excavated, the exposed part of the stele became larger and larger. Finally, when they continued to dig down for nearly three meters, the entire stele was exposed, and at the bottom of the stele, they also excavated A flat land made up of flat stones.

Obviously, the ground below is likely to be the former ground of Mars, and these flat lands composed of stones are the ground of the Martian civilization city.

However, it can also be seen from here that the former Martian civilization may not have such things as asphalt cement, but from the gaps in the middle of these stones, it can be clearly seen that the gaps between these stones have been filled with adhesive.

And even after such a long time, these adhesives are still working. Although there is an effect of the Martian environment, these adhesives will not be oxidized due to oxygen, but But how about it, this is definitely better than those cement and other adhesives in human civilization.

Moreover, it can also be seen from this that the previous civilization of Mars was definitely not low in civilization, and even surpassed the technological level of the current human civilization.

Although everyone was very excited again, no one got out of the car. Instead, they used the mechanical arm of the excavator to completely take the stele out of the ground, and then put it on the car body of the Mars rover. , and then started digging again.

In fact, the excavation of ruins on Mars also has better conditions than that on Earth, that is, because there is no oxygen on Mars, so when the items in the ruins are dug out, they will not be placed due to the interaction with oxygen. function, so that the item deteriorates quickly.

Take this stone tablet as an example. When it was just dug out, the color of the whole stone tablet was snow white. According to Guo Feng's speculation, the surface of this stone tablet may be painted with an unknown paint. However, if it is in the environment of the earth, then these objects will definitely deteriorate if they are buried underground for a long time, exposed to light, and then exposed to oxygen.

As the excavation continued, Guo Feng and the others soon had new harvests, and this time the harvest was not stone tablets, but many cold weapons similar to spears, and the material they were made of was also a very hard And very elastic metal materials, at least not inferior to some special materials in the current human civilization society.

Of course, compared with the most advanced special metals of human civilization, it still has a very big advantage, but if compared with the most advanced special metals of human civilization a few years ago, it can still be slightly better.

This also made Guo Feng and others very strange. After all, judging from the material of this spear, the metallurgical technology of the Martian civilization was already very developed, and its degree of development has reached a level comparable to that of human civilization in Tiangong technology. It is not as developed as it was before it appeared.

However, these spears on the ground are obviously not for decoration, because both sides of the spears have been unsealed, and some spears have been curled at the unsealed parts on both sides, and some spears even seem to have been subjected to severe blows. It seemed that they had been broken into two pieces. It was obvious that these spears became like this after a lot of fighting.

Unfortunately, they did not dig up any biological remains where they were. After all, according to previous data, Mars civilization has disappeared for more than 100 million years. Such a long time is enough for any biological remains. All turned to dust.

At the same time, during their excavation, although Guo Feng and the others also dug up some architectural traces of the Martian civilization, due to the change of time, these architectural traces have become unconfirmable, and nothing can be found at all.

However, even so, what Guo Feng and the others have gained this time has exceeded their expectations, so at this time they are still full of confidence and continue to excavate this ruins, because they believe that as their excavation continues, More valuable things will definitely be found, along with the reason why the Martian civilization will be destroyed.

Of course, regarding the current discovery, Guo Feng and the others reported the news to the base on Mars as soon as possible, and then the base transmitted it back to the command center on Earth. After hearing the news, everyone in the command center was in high spirits. Zhen, because the discovery of these things proves that their previous calculations and guesses were not wrong. In the past of Mars, there really existed a smart civilization, and it was a highly developed civilization, but it has disappeared in the long river of history now. , As for the possible reason for the disappearance of civilization, it still needs to be further explored.
