Chu Hao followed Xiaocao to the depths of the valley, where there was a cave.
Xiaocao walked in first, with Chu Hao following behind. He continually observed, noticing that the cave was very large, large enough to allow a plane to enter, and as they kept walking deeper into the cave, there was no sign of it getting any smaller.
They were slowly descending.
After walking for half the day, a huge space suddenly appeared in front of them.
The previous cave was already very large, but compared to this newly emerged space, it was like comparing a minor witch to a grand sorcerer, a vast difference.
Both the cave and this underground space were filled with flickering green lights. They weren't particularly bright, but they were sufficient to clearly see the contours of the space.
What shocked Chu Hao wasn't the enormity of the underground space, but that this huge space was filled with skeletons everywhere.
