The Nine-Calamity Corpse King

Lu Jiuyuan, a modern surgeon, dies after a patient's family takes revenge on him for a surgical error. His consciousness plunges into the blood-mist-shrouded “Rift of the Yellow Springs,” where a voice claiming to be the “remnant will of the Corpse Ancestor” drags him into the realm of the undead. Here, zombies are ranked across eight realms: Purple Stiff (the lowest), White Stiff, Black Stiff, Hairy Stiff, Flying Stiff, Wandering Corpse, Floating Corpse, and Unchanging Bone. High-ranking zombies control the rules of the realm, while the low-ranking ones are enslaved and devoured like ants.
