Shen Lingyi, a famous teacher in the modern public examination, assumes the role of the headmaster of a dilapidated female school in the Great Zhou Dynasty. She rescues Jiang Heng, a digital genius who was sold into marriage by his parents for fifty taels, in front of a red sedan chair at the beginning. Instead of joining the officialdom herself, she uses the loopholes in the imperial examination, women's system subjects, account book auditing, disaster relief practice, prison reasoning and military supply dispatch to train a group of female officials, and let them step by step from the white list into the court, and eventually rewrite the rules of "who can be an official" in the Great Zhou Dynasty.
