During the Chongzhen period, after her father's tragic death due to the ban on books, Shen Yunshu, a talented girl from Jinling, tore up her skirt, tied up her black hair, and entered the male-dominated imperial examination battlefield under the pseudonym "Shen Yanqing". A blood-stained fish-shaped jade pendant, and half a volume of "Tiangong Kaiwu" with hidden secrets, involved her in the mystery of imperial examination fraud that spanned twenty years.
On a moonlit night in the academy, she had a chessboard confrontation with the mysterious student Xie Mingyuan, but her daughter's body was exposed because of the rouge mole behind her ear. In this game where the world is at stake, the most difficult thing to decide is not the case, but the sentence hidden in the annotations of "Nine Chapters of Arithmetic" on the night he took her hair off: "We are willing to join the branches and break the blue cloud wall together."
Intention: No questions about the West and the East
