In the world, there are many monsters, some of which are similar to humans, or some are very different from them.
The reason why the world is afraid of monsters is not because of the monsters themselves, but because of the regret, guilt and hatred deep in their hearts. Thus, the Demon Subduing Master was born.
Heng Wu and Liu Yuanxi both belong to the same lineage of the Qiansi Sect. They have spent their entire lives practicing to capture monsters. Monsters have no intelligence and their thoughts are chaotic and disorderly, but is this really the case? What is a demon and what is a human being?
The skin-picking demon in the gambling house in Xishan, Kyoto, the drowning demon in Wanghe Village, Linzhou... One by one, the corpses are resurrected and transformed into demons, pouring out their undying resentments. I don't know since when, monsters seem to have gained spiritual intelligence. So, should they still be exterminated?
Intention: Why am I so nervous about catching monsters?
