The Dajing Dynasty ruled the world with literature, and the aristocratic families relied on their collection of classics and literary names to establish themselves. The concubine Shen Qingci is the most unpopular child of the Shen family, a family that collects books. She has been obsessed with classics since she was a child. However, due to her humble biological mother and quiet temperament, she is regarded as useless by her clan members. In her previous life, she devoted all her life's knowledge to helping her sister-in-law Shen Qingyao win the title of crown princess and compile a collection of books for the family. However, in exchange, her biological mother was framed and sentenced to death, she was silenced by her sister-in-law and her fiancé, and the Shen family was also tragically destroyed due to being involved in a dispute over the throne.
Once reborn, Shen Qingci returned to the age of fifteen. At that time, his biological mother was still alive, his sister's conspiracy was revealed, the engagement was not solidified, and the family crisis was still hidden in the dark. This time, she put away her innocence, used her wealth of knowledge as a blade, and used ancient books and secrets as a strategy. She took off her frail coat and transformed into a wise man who takes care of everything step by step. She relied on her knowledge of phonology to decipher the forged letters from her eldest sister, and used her knowledge of the official system to resolve the crisis in which her family was framed. She used lost classics to compete with powerful officials, and even unexpectedly awakened the secret key to the Shen family's ancestral book collection, uncovering a centuries-old mystery of the dynasty's unresolved documents.
In the process, she meets Xiao Jingyuan, the forbearing and dormant seventh prince, by chance. The two go from testing each other to fighting side by side - Shen Qingci uses his literary knowledge to help him break through the conspiracy trap, and Xiao Jinyuan uses his power to support her on the road to revenge. Faced with the constant pressure of his sister, the family's profit calculations, and the turbulence of the court, Shen Qingci not only had to kill his enemies and protect his biological mother, but also, as a female, reversed the prejudice that "it is a virtue for women not to have talent", took charge of the world of classics, rewrote the fate of the family and the dynasty, and finally lived a life that he had never dared to imagine in his previous life.
