The Chinese text is expressed differently, but the general concept remains the same. Below is a possible restatement of the passage:
Xinwen, a history student, is engulfed in a library inferno, and as she loses consciousness, she sees a strange woman before awakening in a dissimilar realm. From there, she learns she is Princess Wenxin Li, the only magical entity in the Flower Nation's imperial dynasty, and is tasked with a political union within the United Realms. Xinwen, an outsider and unskilled sorceress, struggles with numerous obstacles and must evade those after her life while attempting to solve the mystery of the former queen's appearances in her visions.
