The Mirror: Twin Cities

There are three tribes in a fictional universe named Yun Huang: Quan Xian, Kong Sang, and Cang Liu. A century ago, the Cang Liu launched a plot and took the empire that Kong Sang had built. Zhen Lan, a Kong Sang prince, fought Cang Liu on the battlefield all the way to the end. Cang Liu then sealed his emperorship over him. To prevent them from being massacred, the six young monarchs of Kong Sang, including princess Bai Ying, locked all of their tribal members under the Mirror Lake. After a century, the Cang Liu Empire was battled against by Kong Sang and the youthful heir Su Mo from Quan Xian. Su Mo attained the power of the Dragon God after overcoming many challenges, and Zhen Lan unlocked the might of the Emperor. They succeeded in overthrowing the Cang Liu Empire and establishing peace in Yun Huang.
