Feng Qingwan, the most favored princess of the Dajing Dynasty, single-handedly stabilized the situation and shocked all parties. However, on the eve of the canonization ceremony, she was assassinated. When she opened her eyes, she was transformed into the body of a modern cannon fodder girl with the same name. The original owner was cowardly and could be bullied. He was teased by his stepmother and step-sister, humiliated in public by his fiancé, and finally committed suicide due to depression, which allowed Feng Qingwan to be reborn. Feng Qingwan, who has the mind of a princess and the skills of an emperor, looks like a weak white flower on the outside, but is a decisive and killing king on the inside. She activates her portable golden finger - the "Qing Wan Mirror" that can see into people's hearts, and starts a refreshing battle of wits. Facing the difficulties of her stepmother and stepsisters, the provocation of her ex-fiancé, and the covetousness of the villain forces, she worked step by step and planned at every level, using ancient tactics to play with modern life, slap the best in the face, regain the family property, and establish her own business territory. Those who tried to control her will eventually be crushed by her, and in the battle of wits, she met the person who understood her, protected her, and walked side by side with her, and lived a more dazzling life than her previous life.
