Legend speaks of Yun Huang, a paradise created by the gods—but for Na Sheng, fleeing turmoil in the Central Districts, this mythical land proves far from idyllic.

A century earlier, Su Mo, once a lowly slave of the Quan Xian tribe, met Bai Ying, the future Crown Princess of Kong Sang, at the sacred Mirror Tower. Tasked with entertaining her, Su Mo unexpectedly won her heart. But when Bai Ying lost her claim to the royal seal, she chose to leap from the tower, unable to fulfill her destiny.

Now, a hundred years later, Bai Ying awakens from her slumber to find Kong Sang in peril. Meanwhile, a powerful Su Mo returns to a Yun Huang controlled by the tyrannical Cang Liu. As ancient threats rise once more, the two must reunite to face a danger that threatens them all. But can Bai Ying’s love heal old wounds, or will Su Mo's desire for revenge consume everything?
