The terrain detector shows that Jiang Le is not at all worried about the lunar underground. He has also turned on the thermal imaging function of the Tianyan live broadcast. If there are any alien monsters under the moon and only the other party has body temperature, he can't escape the detection of the Tianyan live broadcast.

Therefore, Jiang Le's situation is still very safe, but it seems very dangerous to outsiders.

After climbing down along the edge of the crack for hundreds of meters, Jiang Le stepped on the ground and landed completely.

At this time, the depth is out of reach, and the light diffused from the outside can not be seen at all. Fortunately, Jiang Le has night vision ability, but it will not be affected.

It has to be said that the underground of the crater looks no different from the valleys on the earth, that is, it lacks plants. Everything looks bare and will appear unique.

According to the display route on the terrain detector, Jiang Le began to look for the channel that can lead to the mysterious space thousands of meters away. Through the display of the terrain detector, you will find that the deeper the moon goes, the more cracks there will be. To describe it, it is really like an ant nest.

The terrain here is complex and rugged. Without a terrain detector like Jiang Le that can see the direction of all roads, even people with a good sense of direction will get lost in less than half an hour.

After finding the right way, Jiang Le went all the way, very fast.

On the moon, because there is no atmosphere, the temperature difference between day and night is very large. At night, the average temperature at night will drop to - 153 degrees Celsius, and the lowest can even reach - 180 degrees Celsius.

For astronauts who go out, leaving the spacecraft at night is like looking for death. Even if the spacesuit has the function of regulating thermal insulation, you can't withstand the cold.

Although Jiang Le's physical ability is very strong, he can't guarantee that he will be able to withstand such a low temperature, so Jiang Le gives himself a standard time. Once it is close to night, he must hurry back, otherwise once the night comes, it will be really dangerous.

In the gravity environment of the moon, Jiang Le's speed of traveling is very fast, which can easily reach four times that when he was on the earth. It looks like a distance of thousands of meters, but it didn't take more than ten minutes. When a huge dark space was exposed in front of Jiang Le at the end of the crack, he immediately stopped his steps and his face was tense.

This is an obviously artificially created underground space. On several sides of the space, there are still laying similar to aluminum plates. With Jiang Le's eagle eye vision, you can even see an alloy pipe exposed outside the wall.

"This!" Jiang Le's eyes widened.

Below where he stood, there were still many odd shaped columns and some rectangular earth bags.

[am I right? Are those metal plates and pipes?]

[lying trough, the fact that civilization once existed on the moon has been irrefutable. Who dares to refute it]

[I'm stupid. There's really a global nuclear explosion. It's hard for aliens to say. Anyway, civilization once really existed on the moon. It's too high! I'm glad to live in the age of brother Jiang. He made such secrets public for us]

[then why did this civilization disappear at the beginning? I'm curious]

Jiang Le calmed down his mood and began to walk towards the pillars and mounds below.

Generally speaking, columns have decorative elements in any civilization. If you can find information about who made this place from these columns, Jiang Le's trip will be a major breakthrough.

In front of a column closest to him, Jiang Le began to look at the surface of the column. Looking at it from a distance, he won't feel that these columns are very large. However, as soon as you get close, you will find that these columns are more than ten meters high, surrounded by three people, and there are many patterns like circuit diagrams on the surface.

Based on his previous exploration experience, Jiang Le can conclude that this is definitely some kind of communication text, and it is older than cuneiform text.

At this stage, Jiang Le can't crack it by relying on light blue No. 1. This involves the core carrier of another brand-new civilization. Unless the power of all mankind is taken out, it will be difficult to make a breakthrough in hundreds of years.

The lines on each column are different. Jiang Le asked the Tianyan live broadcaster to record all-round shooting, and he went to a rectangular mound not far away.

These mounds are stacked in a square way. Without professional tools, it is absolutely impossible to build this effect. Taking out the terrain detector, it seems that there are opaque objects in these mounds. With curiosity, Jiang Le reached out and began to dig the mound, intending to dig the mound on his own.

This is a long process, but fortunately, Jiang Le still has time and can stick to it for a few more hours, but if he can't dig it after a few hours, he can only set off to return to the jade rabbit and come back to continue his work after the night.
