The cave entrance was only a few dozen meters from the ground, so with the Steel Rebar shovel in hand, Chen Mo did not waste much time climbing down.
He was only this slow because he was carrying Nangong Xue on his back. Otherwise, jumping straight down would have been easy.
Once they reached the ground, they found it was extremely uneven, covered everywhere with rocks, dirt, and other debris. It was clear that a collapse had occurred here, and no one had come back since.
Chen Mo and Nangong Xue slowly walked along the edge of the stone wall, observing as they went. In some places, the space was over a hundred meters high; in others, it was around two hundred meters. The differences were enormous.
This also made the ground rise and fall constantly. Where there was dirt, it was loose as well; one step could sink all the way to the ankles.
After passing a slope, Chen Mo discovered a huge gap. It was shaped like a funnel, with an entrance roughly ten-plus meters wide and nearly ten meters high, about ten-plus meters above the ground. However, even when the high-intensity flashlight shone on it, he could not make anything out. Standing on the ground and looking up, he could not see inside.
Chen Mo examined it and felt that this might have originally been connected to the tunnel they had come through. Although they were not in a straight line, mine tunnels were not likely to have been dug in straight lines anyway.
Perhaps when the workers had excavated this area in the past, a mine tunnel had connected through here. But some accident had caused a geological collapse, creating a space larger than the current one.
Then, because of a second collapse, a large-scale cave-in
