In a fantasy world called Yun Huang, there exist three tribes Quan Xian, Kong Sang, and Cang Liu. A century ago, the Cang Liu started a conspiracy and seized the empire created by Kong Sang. At the battle field, Kong Sang prince Zhen Lan fought against Cang Liu until him the last one. His power of Emperor was then sealed by Cang Liu. The six young kings of Kong Sang, including princess Bai Ying, sealed all their tribal people under the Mirror Lake in order to protect them from being massacred. After a century, the young heir Su Mo from Quan Xian allied with Kong Sang and fought together against the Cang Liu Empire.
