Zhu Ling owes the system an enormous debt of 600 million and is forced to travel back in time to ancient Qinshui Village. Taking the place of a poor young woman named Zhu'er, she must care for her injured adoptive parents while dealing with the malicious schemes of her uncle's family. Her system does nothing but munch on sunflower seeds and demand repayment, offering no special powers whatsoever. With only her own intelligence to rely on, Zhu Ling struggles to survive. Starting with soybeans, she develops tofu-making techniques, seizes opportunities to build a business from scratch, helps the entire village establish tofu workshops, and eventually invests in restaurants to expand her commercial empire. While earning money to repay her debt, she also rescues women suffering from oppression and establishes workshops to help them become self-reliant. Despite one crisis and conspiracy after another, Zhu Ling overcomes every obstacle through her own resourcefulness. She needs no romance, relying solely on her own strength to carve out a vast world of opportunities for women.
