Lin Feng and his wife Su Ling'er started a business together after graduating. After the company went public, he stepped back from the limelight, willingly becoming a househusband out of love, and binding himself to a Sign-In System. He needed to sign in at home for 3 years to receive the system reward. On the very last day of his successful sign-in streak, his wife came home with her lover, demanded a divorce, and insisted he leave with nothing. Lin Feng promptly completed his sign-in, obtained the system reward, and signed the divorce papers. He then showed his extraordinary abilities at lottery shops, antique streets, gemstone gambling workshops, and the stock market, meeting three women who became close companions along the way. Later, he made his ex-wife and her family face the consequences of their actions, rose to the pinnacle of success, and lived a fulfilling and happy life.
