When Gu Changning, a doctor of agriculture, opened his eyes, he turned into a foolish concubine who was forced into a sedan chair to get married. Prince Yong, who had killed three wives, was waiting for her to surrender, and her close relatives, who were full of scheming people, were waiting for her to accept her fate and die. But she didn't. With the secret method of breeding in hand and the saline-alkali wasteland under her feet, she started from an experimental field, established a commercial bank, set rules, created a bank, and established commercial laws, and used modern business thinking to make waves in the ancient dynasty. There is no heroic prince to save the beauty, no male protagonist to protect her affectionately, only a woman using abacus and contract to carve her trust into the bones and blood of Daliang. When the former concubine stood in court and competed with the prime minister for the power to set the rules, people all over the world understood that she didn't want anyone's favor. What she wanted was for the whole world to run according to her rules.
