Zhu Moyan, a "salted fish" young man who was forced to inherit the family business, appeared to be a playboy who spent all day playing mahjong in teahouses, but in fact he was the top psychological warfare master in the "Raven" organization in his previous life. In his previous life, he was killed by a trick by the men of the warlord Zheng Yanwang. He was reborn in Dragon City in the 1930s and possessed the body of a prodigal son also named Zhu Moyan.
