Chu Ge walked to Yu Gong. He needed them to measure the specific rock structure in this area before they could determine the specific drilling location of the drilling team.

Yu Gong and the others were busy and did not notice that Chu Ge had come to them.

Chu Ge didn't have the nerve to disturb them, so he just stayed there quietly.

After a while, Yu Gong discovered the existence of Chu Ge.

"Academician Chu, when did you come here? Sorry, I was just busy burying instruments and equipment."

"It's okay, I just want to take a look. Are you planning to use the three-point measurement method to measure the structure of the rock formations below?"

"Yes, the main purpose is to determine the tilt direction and trend of the structural plane. Academician Chu also knows about geological exploration?" Yu Gong raised his head and asked a little surprised.

"What do I know? I only know a little bit about it." Chu Ge replied awkwardly.

“The most direct way to explore unfamiliar areas in the wild is to use a geological compass and GPS. These two pieces of equipment can accurately measure the direction, tendency and inclination of rock formations.”

"Obviously, neither of these two can be used here. We are going to use the most primitive method with basic tools such as laser rangefinders and levels and some scientific methods to determine the general direction of the rock formations here."

"It may be necessary for the drilling team to conduct experimental geophysical exploration in these places we have circled in the future. The geology here has no outcrops, and we cannot draw a cross-sectional structure map of this geology based on it."

Yu Gong briefly said a few words to Chu Ge, then lowered his head and went back to playing with the instruments.

An expert next to the two of them was recording something on an electronic instrument.

Just when Chu Ge was about to go over to see what he was recording, the mask panel prompted a call request from [Soul Blade], and Chu Ge walked aside.

"How about it?"

[Report to General Chu that the gravity anomaly area is a circle, and it is a very standard circle, just like drawn with a compass.]

[It has a diameter of 5,000 meters, which is slightly larger than this sunken basin. From a high altitude, it actually looks more like a huge crater. 】

"Well, I know this is a crater. We are on the ground and have limited sight. You can walk around again to see if there are any other abnormalities. Report any situation in time."

【Yes, General Chu.】

Chu Ge cut off the call and walked back to where Yu Gong and the others were working, only to see that Yu Gong and the others were already using some kind of engineering paint to mark the drilling site.

"How is it? Can we drill?" Chu Ge asked excitedly.

"Okay, Academician Chu, let the drilling team bring the two largest drilling equipment over."

"good."

After Chu Ge replied, he immediately connected to Captain Wang Lin via voice.

"Captain Wang, bring the two largest drilling equipment to my place, yes... um..."

After Chu Ge finished speaking, he cut off the call and called Yu Gong and the others to step aside.

Soon, the two drilling equipment were in place. After communicating with Captain Wang, Yu Gong stepped aside. Captain Wang finished debugging the equipment and then turned off the machine.

The huge drill bit began to rotate and penetrated into the ground fiercely. At this time, Chu Ge remembered a joke he made with Sister Moon one day on Earth...

The soil and rocks brought out by the rotation of the drill bit fall down in all directions with the force of rotation.

The soil was very fine but did not spread out at all. It fell in a parabola like a water curtain fountain and soon piled up into a circular hill.

Several small bulldozers began to clear these hills. When the drill bit was about to reach the top, Captain Wang Lin made a stop gesture.

The huge drill bit immediately spun out and then stopped spinning.

Thanks to the near-vacuum environment of the moon, this behemoth, with a maximum drilling diameter of more than 7 meters, made no sound when working.

A huge cave appeared in front of everyone on the surface of the moon, with a diameter of nearly 7 meters, which is much larger than an ordinary well.

"Yu Gong, do you need to increase the length?" Captain Wang walked up to Yu Gong and asked after a while.

Chu Ge knew that single communication was a bit troublesome now, so he simply opened the team communication permission so that everyone could communicate freely.

"Captain Wang, please stop for a moment. Let's go down and take a look at its layered structure."

"good."

After finishing speaking, Gong Yu began to greet several young engineers to arrange the lighting equipment. When everything was ready, several people took the temporary hanging ladder and slowly went deep into the huge shaft.

Chu Ge and Captain Wang Wang were idle on the surface and began to study the thrown debris.

After watching it for a long time, Chu Ge gave up. It was all mixed up, and there was no clue at all.

After a while, the hanging ladder moved. Chu Ge and the others hurried over. After a while, Yu Gong and the others poked their heads out.

"How is it?" Chu Ge asked hurriedly after a few people came down.

"Academician Chu, the rock structure here seems to have been destroyed, and its direction and cross-sectional structure cannot be seen at all."

"Ah? Is the drilling probe too big and damaged by it?"

"No, the entire rock structure here is fragmented, and our drilling rig will not create this effect."

"It's more like it suffered severe vibration or direct force and then the whole layer broke." Yu Gong explained.

"Earthquake? Ah, no, it should be a moonquake."

Chu Ge could only think of this.

"We have only drilled more than ten meters deep. To be able to damage it to this extent, the intensity of this lunar earthquake must be very strong, but the moon has not had volcanic eruptions for a long, long time."

"Furthermore, the moon's crust does not have continental plate structures similar to those of the Earth. Even if there are moonquakes, the intensity will not reach this level."

Everyone was silent after hearing this.

"From now on, it looks more like it was affected by some kind of external force. We analyzed that it was most likely formed by the impact of a huge meteorite."

Yu Gong said another possibility that several of their geological experts discussed below.

Chu Ge nodded after hearing this.

"Academician Chu, what should we do next? Should we continue drilling?"

The rock formations were chaotic, and Yu Gong was a little unsure about the next direction, so he asked Chu Ge, who had been thinking about it next to him.

"Captain Wang, how many meters can this drilling equipment with the largest diameter drill?"

"With another slightly smaller drilling equipment, the maximum drilling depth is 15,000 meters." Captain Wang replied without hesitation.

"Then continue drilling and prepare the snooping equipment. You don't have to go down, Yu Gong."

"Remember to record every 100 meters. I want to see how confusing it can be."

"Yes!" After the two people next to them replied, they separated and went to prepare their equipment.

Chu Ge intuitively felt that there must be something extraordinary here, otherwise there wouldn't be so many strange phenomena, and it wouldn't destroy anything anyway, so he simply went to find out.
