Su Tangli transmigrates into the body of an unlucky girl forced into a proxy marriage and activates the "Billionaire-Building System." The System tells her that if she helps her husband become the richest man in the world, she can coast her way back to the modern era. The problem is, her husband is a fool laughed at by the whole city, and all he can do is follow her around saying, "Wifey smells so good." Su Tangli rolls up her sleeves. No problem, she has the System. Even a fool can become a billionaire! She grows chili peppers, opens restaurants, and builds infrastructure, leading her husband on a meteoric rise. Her stepsister, who once mocked her for marrying a fool, gets down on her knees and begs to work with her. Su Tangli sneers: Too late. When her foolish husband suddenly regains his memories and pins her against the wall, he asks, "Wifey, now that I'm a billionaire, can I call you something else?" The whole city is in an uproar: The fool was a hidden big shot all along?
