In a world of chaos with demons and monsters, human life is like grass.
Gu Changan was originally just a corpse collector in Qingshi County's Demon Slaying Department. He lived in the coldest yard, carried the dirtiest corpses, ate scraps, and did the job that was most likely to lead to death. Until that rainy night, he found a glimmer of opportunity on the corpse of a demon wolf that should not belong to a mortal.
From then on, killing monsters can help you live longer, and killing evil spirits can help you maintain your health.
But he soon discovered that the most terrifying thing in the world may not be the monster. The powerful people in the county, the servants in the yamen, the evil worshipers secretly, and even those wearing human skins and sitting in high places are all using monsters to eat people and take lives through chaos.
Since the world does not give him a way to survive, he will use his knife to find a way out.
From skin refining, meat refining, to the sound of muscles and bones; from a corpse collector in a small county on a rainy night, to a demon slayer who makes all the demons turn pale after hearing their blood.
He first kills the evil spirits in the world, and then asks the gods in heaven.
