Xie Chaoyun, the son of a demon-hunting family whose entire family was wiped out, met Cheng Xi, a little girl who had a similar experience to himself, while wandering around, and the two depended on each other for life. Later, he was lucky enough to be accepted as a disciple by master Li Lan, and he studied hard to catch monsters. When he was wandering around the world after becoming a teacher, he unexpectedly met two wealthy young masters Jiang Huaizhi and his daughter Nangong Yiyi (Huan'er) who had run away from home. The four of them shared the same goals and joined hands to slay demons in this treacherous world.
