Shen Zhiwei, a merchant's concubine, once traveled through time and was trapped in a powerful and aristocratic dynasty. She used the account book as a sword and the password as a blade to tear open the iron cage of the family. The third prince Xiao Heming secretly protected her, but he didn't know that she held the secret key of the previous dynasty; Xie Zhaohua, the daughter of the Minister of Industry, and she were both enemies and friends, sharing financial power; the crazy nun in the cold palace, Aunt Liu, handed over a copper coin every night, pointing to the secret code of the burned emperor. When the northern female general Zhao Yanqiu led her cavalry to attack the border, Shen Zhiwei realized that she was not here to seize power, but to return it.
