Chen Fan was originally an ordinary hunter in the suburbs of Qingyang City. He lost his home and relatives due to a sudden demonic disaster, and accidentally awakened the "mortal bones" hidden in his body - a special physique that is not recognized by the world of immortality, but can restrain evil spirits. Under the recommendation of the last elder of the Demon Slaying Pavilion, he embarked on the dangerous path of slaying demons. Holding a rusty ancestral hunting knife, he used a mortal body to fight against the monsters that devour the world. From the sewer demons in Qingyang City, to the thousand-year-old demons in the southern Xinjiang rainforest, to the demonic conspiracy deep in the court, Chen Fan has gone through the test of life and death, met like-minded comrades, and also encountered treachery and betrayal. He not only has to face the ferocity of monsters, but also resist the contempt and calculations of immortal cultivators. As the secrets of "mortal bones" are gradually revealed, he gradually becomes a monster-slaying legend that shakes the three worlds, and finally reveals the ultimate truth about the frequent occurrence of monster disasters in the world and protects the peace of the people.
