Xia Xiaomang is an orphan from Xiajia Village in the Qian Dynasty. She was sold to a cruel butcher by her money-grubbing stepmother Li Juanhua. In desperation, she escapes into the haunted house in the village and accidentally discovers a door that leads to modern society. Taking advantage of the price difference between the two worlds, she sells wild vegetables and mushrooms that were ignored in ancient times at high prices in modern times, and then uses the money she earns to buy scarce food and iron locks in ancient times to improve her life. She cleverly made use of modern materials, successfully separated her family and set up a household under the auspices of the village chief, and got rid of her vampire mother's family.
