Chronicles of the Ghostly Tribe

In 1979, the bones of a mysterious creature were discovered in a cave in the Kunlun mountain range. Hu Baiyi leads an expedition into the depths of the mountains in search of more paleontological relics. As they descend, they discover an underground city belonging to a lost civilization that possessed great power and knowledge of life and death. However, their joy is overshadowed by the presence of large and aggressive creatures that attack the group.
