In her previous life, Sheng Shengnan was determined to marry into a wealthy family, only to have her heart broken. Given a second chance on the day of her college entrance exams, she decides never to depend on a wealthy family again. Armed with her foresight, she invests her modest savings in the semiconductor industry. She invests in struggling Yuanshan Semiconductor, fights relentlessly for independent research and development, and joins forces with an AI entrepreneur to overcome challenges in developing China's own memory chips. Facing fierce international competition, she keeps control of the core technology and decision-making power in her own hands, refusing to let her birth family arrange her marriage. When her wealthy ex-boyfriend proposes to her in public, she calmly turns him down, proving that a woman's worth is not defined by marriage. From an ordinary girl to a female entrepreneur commanding cutting-edge technology, she builds her own security without relying on wealthy families or men to lift her up.
