At the bottom of the deep pit, Lei Wenjun was entranced, staring at the wall of the pit beside him.
Right where his left hand touched, there was a striking piece of gray rock sprinkled with white phenocrysts—or rather, a complete rock wall.
This rock wall appeared about five or six meters above his head and extended downward, with no end in sight.
As a geological expert, Lei Wenjun determined the rock type almost immediately upon seeing this rock wall.
It was for this reason that he was trembling all over with excitement, looking just like Wu the Second.
However, Lei Wenjun's trembling didn't last long before it was interrupted by Lin Ziming.
Lin Ziming's voice came through the earpiece once more, even more urgently than the first time:
"Director Lei, are you okay?
Your blood pressure and heart rate are rising sharply, exceeding certain limits, please respond immediately, please respond immediately!"
