The Great Yong Dynasty was peaceful on the surface, but in fact the court and the academy were jointly controlled by a "Spring List". Anyone who could leave his name on the list could change the fate of a city or a place. Seven modern female academics collectively traveled to Dayong on the night after the college entrance examination, and fell into different identities: the concubine of the Hou family, the female doctor, the shopkeeper of the embroidery workshop, the "younger brother" of the down-and-out son, the female historian in the palace, etc. Each of them was bound to an "annotation system" with different functions. They must collect the "fragmented pages" scattered throughout the year, otherwise they will be trapped in ancient times forever.
The heroine, Jiang Zhaoxue, disguised herself as the legitimate daughter of an official family who was sent to Zhuangzi to "recuperate", but found that she could still wear the identity of her deceased brother and enter the Imperial Academy as a man to investigate the case; what is even more troublesome is that the spring list seems to be tampered with, and all records of women's talents and learning are disappearing page by page. While she was contacting the sisters who had also come through the same time, she was dealing with Pei Guanlan, the cold-faced prince who was ordered to investigate "the strange movement in the Heavenly Book", and they solved the problem side by side in mutual testing.
This is not a simple imperial examination, but a group of smart girls using vests, systems and knowledge to forcefully open a crack in the ancient rules and compete for a position where "women can also sign their real names".
