The day she transmigrates back, her mother-in-law wants to sell her daughter and is waiting for her to starve to death.
Shen Jinxiu transmigrates from the 21st century to an imaginary ancient dynasty. When she opens her eyes, she finds a drafty shack, an emaciated husband, and three daughters who are afraid of her. The rice jar is empty, heavy snow seals the door, and her mother-in-law forces her to sell her eldest daughter for money.
She refuses to accept her fate.
She digs up potatoes in the mountains and earns her first fortune by frying them. She starts a factory, grows potatoes, buys a tofu shop, and opens a chain of stores, while helping her husband, Mo Yanli, pick up his books again. He passes the palace exams as the top scholar and rises to become Minister of Works. She builds a commercial district, develops real estate, constructs an amusement park, helps the imperial court build waterworks and divert water from the south to the north, and even teams up with the emperor to make money.
But this is not her story alone.
Her three daughters grow from timid girls into independent women: the eldest trades overseas and brings back golden corn, the second captures the Jiangnan silk market and marries a prince, and the third disguises herself as a man to join the army and defend the frontier. Each one works toward her own legendary life.
Amid court struggles over the throne, business associations trying to suppress her, and tests of imperial authority, Shen Jinxiu uses wealth and wisdom to overcome one crisis after another. Her husband refuses to take concubines and cuts ties with his relatives for her. The emperor honors her as "the nation's virtuous merchant," and the common people celebrate her name.
Watch her rise from a broken shack to a commercial empire, from being scorned to being admired by all. She originally only wanted to make money, protect her husband, and educate her daughters. One mother supports her entire family and, along the way, accidentally changes an era.
