In ancient times, the four disciples of Xiye, ruler of Heaven and Earth, were renowned across the Six Realms. Feng Ziqing, the Demon Venerable, had extraordinary talent and was greatly valued by their master. Liu Liyue, the Moon Venerable, and Jun Ao, the Sword Venerable, fought side by side. A perfect match in both talent and looks, they were considered made for each other. Meanwhile, the then-unknown Xuan Jihuang quietly stood behind the others, head bowed as she listened.
Yet in the end, it was the unremarkable Xuan Jihuang who inherited the title of ruler of Heaven and Earth.
A thousand years later, the Moon Venerable was reincarnated as Lan Suiyue, an imperial princess of the Divine Realm. In her encounters with the Sacred Venerable Xuan Jihuang, Lan Suiyue seemed to catch a glimpse of the secret from a thousand years ago.
