In order to survive, Shen Wan, a woman from a humble background, orchestrated a "fake death" escape from the Hou Mansion and came to a small and barren border county. She made her debut and started selling goods at a stall. With her amazing talent in mathematics and precise control of human nature, she made her way in the mall step by step. At first, she was regarded as a profiteer by Xie Lan, the newly appointed iron-faced county magistrate, who used this as a profiteer. The two were tit-for-tat on people's livelihood issues such as road construction, food prices, and taxation, but they had to borrow each other's strength in the process of governing the local area and fighting against the wealthy gentry. Shen Wan paved the way with money, Xie Lan escorted him with the law, and the two joined forces to fight back to the capital from the county seat. In the end, Shen Wan not only became the number one imperial merchant in the world, but also revealed the mystery of her life experience and recovered all her "debts" from the Hou Mansion that had bullied her.
