Lin Yi reached his hand out to touch the wall, only to find that his palm was buried in the rock.
"Hehe ... It's a fake mountain wall! A 3D projection?"
Lin Yi felt the cold metallic touch on his palm and shook his head,"It seems that this is Central's base!"
After mumbling to himself, Lin Yi turned into his essence spirit and went in silently.
Behind the virtual mountain wall was a huge, heavy steel door with the most modern locks, but Lin Yi didn't need to open it at all-his spirit floated in.
Behind the gate was a steel-cast passage, and LED lights were installed at intervals along the passage. It looked very sci-fi, and it shouldn't have appeared in a place like Sky Class Island.
Other than the center, no one would build such a building.
Lin Yi sent out his spirit sense, but he didn't find any signs of life. This made his heart sink!
