On the day of the wedding, her fiancé Lu Jingchen regretted his marriage in public, hugging his true love and calling her a "high-flying Cinderella". Lin Mengyao was wearing a wedding dress and was humiliated by 300 people. But just when she was desperate, she bound to the "rich family counterattack system" - as long as she spends the scumbag's money, she can get ten times the rebate! So she used the breakup black card given by Lu Jingchen on the spot, spent his money to buy the entire wedding, spent his money to acquire his company, and spent his money to make him go bankrupt step by step. From the down-and-out daughter who was kicked out to the vengeful queen who annexed the Lu family's business empire, Lin Mengyao only used one system - and an unexploited secondary card. When Lu Jingchen knelt in front of her and cried and begged for mercy, she threw down a check: "This is the breakup fee you gave me back then. I will pay you back double and use it to start over." Then she turned around and her high heels crushed the last trace of his dignity. Three years later, her name appeared at the top of the wealth list, and the man who had humiliated her could only work as a waiter at the charity dinner she hosted. This turnaround started with her maxing out a card.
