After thinking for a long time, he couldn't help but quietly walk to Chi Jiazhen's side and quickly tell her what he knew about the students in the green camp who might be involved in command, as well as their respective relationships.

He remembered everyone's family, gender, and even personality perfectly... Because of his nervousness, he spoke softly and quickly, but Chi Jiazhen still looked at Lou Miao'an after listening.

"...W-what's wrong?" Lou Miao'an stammered, not understanding why Chi Jiazhen was looking at him so probingly.

"It's nothing." Chi Jiazhen didn't mention that he and Cen Yu had just switched to a one-on-one call channel.

Because they were so close, Cen Yu heard Lou Miao'an's entire voice, even though it was soft and quick.

“Xiao Yu.” Chi Jiazhen looked at the 3D terrain map projected in mid-air. “Follow my instructions. Now walk 40 degrees clockwise. You will see the carcasses of dead animals there.”

"Move aside the remains, dig down 2 meters, and you'll see the buried entrance."

...

Listening to Lou Miao'an's soft voice, Cen Yu understood how the other party had managed to snipe those Alphas in the original work.

They know their personalities so well... as well as their family influence and individual abilities...

Although he didn't understand how the pairing of Chi Jiazhen and Lou Miaoan came about, he thought about it again and realized that they were roommates, so it wasn't surprising that they would temporarily form a partnership.

Following Chi Jiazhen's instructions, he quickly found the entrance.

This place was quite far from where they had originally landed. Cen Yu quickly manipulated the mecha to move away the unrecognizable animal carcass—it was a full 3 meters tall and completely different from anything Cen Yu knew—and after digging open the entrance, he saw the combination lock on it.

“…” Cen Yu was speechless. “It has a combination lock.”

"Can it be forcibly untied?" Chi Jiazhen asked.

“Okay.” Cen Yu said, and the robotic arm exerted force, cutting the door open directly.

Then, he skillfully piloted the mecha and jumped into the space.

The underground space was limited and not enough for such a large mecha to move around underground... So after entering, Cen Yu immediately retracted the mecha into the mecha lock and then began to look at the area in front of him.

This area looks like it was rebuilt from the tunnel that the mutated beast originally dug.

Even after many years, and with the ground covered in dust, one can still vaguely see its original pristine appearance... The ground was cast with some kind of special metal, and the walls on both sides were made of a material that prevents scanning. Although it looks somewhat outdated now, it was clearly a technological fortress back then.

Cen Yu took out his earphones, put them on, and spoke to the other end.

"This doesn't look like it was dug out by a mutated beast."

"Hmm, this seems to be an abandoned laboratory," Chi Jiazhen said on the communicator. "The Green Faction doesn't seem to have discovered this place either."
