Cemetery administrator Li Muyun clicked on a strange check-in notification, and a warm and strange rain of agave fell in the cemetery late at night. He was forced to shuttle between the Mayan city-state of the 16th century and the bizarre virtual fairy world, and his identity switched between a tomb keeper, a ball game player and a luck monk. The appearance of archaeologist Lin Wanzhao allowed the two people's fragmented memories to gradually piece together the shocking truth: the so-called demise of the Mayan civilization was actually a successful full-dimensional migration. Now, the ancient ball game ritual that maintains the two worlds is on the verge of collapse, and the boundaries between virtual and real are dissolving. Li Muyun must use the eyes that can see cracks in his sickly body to find a third way to prevent the two civilizations from being annihilated together amidst sacrifices, cultivation, and the siege of time and space bugs - even if the price is to become an eternal tomb guardian who wanders outside all dimensions.
