Legend of Youli.

In the beginning of times, humans and demons existed side by side in peace. Thousands of years later, the master of Youli clan violently launched a war to expel mankind. After hardships, the strange men and strangers expelled them to the depths of the earth and suppressed them with the Qianyuan Immortal Formation. The former head of the Ping You Division, Yi Shui Han, guides the half-human, half-Yuli to gather the Five Noble Ones to reorganize the division. After the human skin case, the emperor also ordered to reopen the Department of Peace and Harmony to find out the truth.
