The demon world went bankrupt, and the three-and-a-half-year-old princess Fu Cheng was coaxed by her father to go to the world of immortality to borrow money from her mother. She recognized her relatives and was dismissed as a liar by the Qingyun Sect, so she switched to the Poorest Tianjian Sect. The Chaos Spirit Root allowed her to practice quickly, and she also burned money to the point of bankrupting the sect. All her brothers and elders doted on her sister to make money. She hides her identity as a demon, makes hilarious counterattacks and slaps her in the face, while searching for her mother, protecting her family, and getting involved in a century-old conspiracy.
