In a time where magic is inherent in the Kunwu clan but Humans can only cultivate it, a war between the two ended with the Dragon Emperor protectively cocooned, but not defeated. Ten years later the last Saintess of the Kunwu tribe (
Jiayi Wu), who had been raised since the battle in seclusion with one purpose, is sent into the capital city of Tianqi to find and release the Dragon Emperor. There she clashes with the Nation-Protector (
Kai Xu), a rebellious but capable young man who holds the role reluctantly. The Dragon Emperor is sealed in the Mysterious Land, a powerful magic place accessible only with a particular token, which Li Xuan, the Nation-Protector, carries. Among their classmates at the Academy are royals, children of important officials, powerful talents and others who have battled their way through admission. With such personages about, political plots and machinations are constantly encountered and interfere with Su You Lian's agenda. Meanwhile Li Xuan, the Prince of Sha (
Junchen Li), and the second son of the Emperor (
Xintong Yu) have all taken particular interest in Su You Lian.
