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

After all, this rover has already taken these issues into consideration when designing and manufacturing, so this rover has many functions. It not only has many scientific research equipment inside, but also has a variety of robots of different sizes on the outside of the vehicle. The largest one can extend to more than 30 meters in maximum length, and can also install a variety of excavation equipment and robots, which is definitely one of the best equipment to explore Mars.

With Guo Feng and his team digging, they soon dug nearly ten meters. Just as they wanted to continue digging down, suddenly, a team member saw something below through the camera at the top of the robotic arm.

So the team member said, "Captain! Stop for a while, there seems to be something down there."

"What's there?" After saying that, Captain Guo Feng also looked down.

Sure enough, he saw a huge stone standing quietly at the bottom of the tunnel they dug out. Of course, if it was an ordinary stone, it would not attract their attention. However, the stone below was obviously not an ordinary stone, but a very smooth rectangular stone tablet around it. Most importantly, there were some patterns and some things like words on the stone tablet.

Therefore, from this kind of evidence, this stone tablet is definitely not formed naturally, but is carved by manual polishing.

In other words, the appearance of this stone tablet has shown that Mars once had the existence of a smart civilization, because only a smart civilization can produce such a stone tablet, and it still needs to be developed when civilization develops to a certain extent, because even primitive civilizations cannot create such a stone tablet.

This made everyone in the entire exploration team very excited, and immediately used a robot to continue digging down. After all, the exposed part of the stone tablet was less than twenty centimeters, so there was still a large part below and it was not dug out.

Sure enough, as they excavated, the exposed part of the stone tablet became larger and larger. Finally, when they continued to dig down for nearly three meters, the entire stone tablet was exposed, and at the bottom of the stone tablet, they also dug a flat ground composed of flat stones.

It is obvious that it is very likely that the ground on Mars once was, and these flat grounds made of stones are the ground in the once Martian civilized city.

However, it can also be seen from here that the Martian civilization may not have anything like asphalt cement, but from the gaps between these stones, it can be clearly seen that adhesive has been filled with gaps between these stones.

And even after such a long time, these adhesives are still working. Although there is the role of the Martian environment, these adhesives will not cause oxidation due to oxygen, but no matter what, this is definitely better than those cement and other adhesives in human civilization today.

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

Although everyone was very excited again, no one got off the car. Instead, he used the excavator's robot arm to completely take out the stone tablet from the ground, then put it on the rover's car, and then began to dig again.

In fact, excavation of ruins on Mars also has better conditions than that on Earth. That is, since Mars does not have oxygen, when the items in the ruins are dug out, they will not deteriorate quickly due to the effects of oxygen.

Take this stone tablet for example. When it was just dug out, the color of the whole stone tablet was snow-white. According to Guo Feng and others' speculation, the outside of this stone tablet may be painted with an unknown paint, which is so snow-white. However, if it is in the earth's environment, then these objects will definitely deteriorate after being buried underground for a long time, and then they will come into contact with light and then oxygen.

As the excavation continued, Guo Feng and the others soon gained new gains. This time the gain was not a stone tablet, but a lot of cold weapons similar to spears. The materials they created were also a very hard and elastic metal material, at least not worse than some special materials in the current human civilized society.

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

This also made Guo Feng and others very surprised. After all, judging from the material of this spear, the metallurgical technology of the Mars civilization was already very developed, and its development level had reached a level that was even more advanced than that of human civilization before the emergence of Tiangong Technology.

However, the spears on the ground are obviously not used for decoration, because both sides of the spear have been opened, and some spears have been curled on both sides of the spear, and some spears have even been folded into two pieces as if they were hit violently. It is obvious that these spears have become like this after a battle.

Unfortunately, they did not dig any remains of creatures where they are. After all, according to previous data, the Martian civilization has disappeared for more than 100 million years. Such a long time is enough to turn the remains of any creature into dust.

At the same time, during their excavation, although Guo Feng and others also dug up some architectural traces of Mars civilization, due to the changes of time, these architectural traces have become unconfirmed and nothing can be found.

However, even so, Guo Feng and his team's gains this time exceeded their expectations, so they were still full of confidence and continued to dig out the remains, because they believed that as their excavation continued, they would definitely find something more valuable, and as they could dig out the reasons why the Martian civilization was destroyed.
