Huang Que Zhuan

An assassin named Yan Po kills all eighteen members of the Huang family in a single night, taking with him the knowledge of a shape-shifting technique before vanishing. One Huang family member survives and seeks vengeance. Seventy years later, the phrase "As the mantis stalks the cicada, behind them will lurk the Golden Sparrow" is widely known in Chang’an, reflecting a determination to see Yan Po return.
