In his previous life, Lin Chen blindly speculated in stocks and fell victim to a scheme. When the market crashed, he died in despair. Only at the very end did he learn that the female lead, Liu Dan, had been running around trying to raise money for him. By chance, he is reborn in his senior year of high school and binds to the Wealth Growth Sign-in System. Starting with 500 yuan, he prepares for the college entrance exam while building his stock-trading experience on campus. When he is down on his luck, Liu Dan unconditionally supports him with her 300,000 yuan in savings. Her trust becomes the motivation that keeps him moving forward. From then on, with stock-trading skills and connections gained through the System's sign-ins, Lin Chen gradually establishes himself in the market and repeatedly face-slaps the rich playboy Zhao Lei. He also makes his mark in confrontations with Wall Street elites and the financial power brokers lurking behind the scenes. After building assets worth trillions, he stays true to his original aspirations and invests in biomedicine to develop a cancer drug. He receives the country's highest science and technology award, and ultimately starts a family with Liu Dan, bringing their story to a happy ending.
