Lin Wan, 34 years old, CEO of the multinational technology group "Star Dome", suffered an unexpected car accident late at night while signing a tens of billions of mergers and acquisitions. When she opened her eyes again, she became Shen Fenglin, the eldest daughter of Duke Jingguo of Daye Dynasty. She has the same name and the same age, but she is a famous "wooden beauty" in Beijing. Due to her mother's early death and her stepmother's suppression, she is about to be married to the King of Zhenbei, who is over sixty years old, to fill a house. On the wedding day, Shen Fenglin tore up the marriage contract in public and used modern business negotiation skills to reach a "three-year agreement" with the King of Zhenbei - to help him rectify the corruption in the military camps in the north in exchange for his freedom. Using modern financial management and supply chain thinking, she discovered a loophole in military pay within three months, brought down three military quartermasters, and shocked the government and the public. A modern female president does not compete for favor in the harem or rely on cheating, but uses business thinking to deconstruct ancient power games. In the process of transforming the times, she completes the cognitive transformation from "conqueror" to "builder".
