The territory of the Heavenly Court's "Abandoned Horse Farm" was gradually occupied by countless cold "Plague Horse Stalls", and an ancient terror - Saddle Plague, began to sweep across all areas where there were people riding horses. The flesh and blood of those infected with the epidemic fester and grow mycelium. They are driven towards the dark wooden pile by this evil thing. The dead horse's carrion turns into a pus and blood inscription, and the seal is carved into a "rotting bone formation" that travels through life and death and reaches the realm of the gods.
"Cleaner" Tang Li, a member of the fringe of heaven who also carries a heavy identity, is responsible for cleaning the black wooden piles and inscriptions with pus and blood to control the spread of the plague. For countless days and nights, she kept scrubbing the solid black pile that her enemy's grandfather had occupied during his lifetime, while fearing the fateful connection that was gradually burying his bloodline. When the new plague swept across the desert and the mall, Tangli met Batu, who was infected with saddle plague again. The "root of taboo" in his chest was taking root and expanding as the poison spread. The awakened monster is dormant silently under the entire abandoned horse farm - will the "Rotten Bone Array" left by grandfather and ancestors be about to be reawakened? What role does Heaven want to play in this?
