Thousand-year-old couple Lin Qingge and Lin Ruoxue accidentally caught a monster and their live broadcast was exposed. They were assigned by the Monster Hunting Bureau to start a live broadcast of monster science. Chihu, corpse chasers, fox demons and other strange people and monsters take turns to appear. They live broadcast the knowledge of Chinese monsters, folk customs and monsters, and deal with cases of human monsters at the same time. There are high-octane fights between monsters such as Zi Zhan and Gu Huoniao, as well as light comedies in which old couples fight each other every day. Mortal cases continue one after another, and heavenly gods often join in the fun across dimensions, revealing the humanistic stories behind traditional monsters during live broadcasts.
