Lin Yan, a modern restorer of ancient books, dies from overwork and becomes an outer-sect woman tasked with copying books in the cultivation world. Her spiritual root has been stolen, her aunt torments her, and her father died under mysterious circumstances. She uses a divine artifact to restore ancient books and earn literary merit, at the cost of losing her emotional memories: she forgets her office, her orange cat, and everything about modern life.
Forced to form a pact to restore texts with Pei Xuanzhou, the cold-faced head of the sect, she agrees to a three-year contract, but he falls for her first. They search an ancient secret realm for fragments of the True Text. The Demon Venerable Ye Canglan kidnaps her to the Demon Abyss and reveals that she is the reincarnation of a sage with a literary heart. Her senior brother Wen Zhe vanishes into ashes saving her. The male lead becomes a demon for her, and she chases after him for three thousand miles.
The Heavenly Dao wants to erase her, and the Demon Venerable wants to rewrite the Heavenly Dao. As for her, she will wield her pen like a sword and rewrite the rules of the entire cultivation world. Governing through both civil and martial means, she writes her way to ascension.
