The ancient country of Loulan collapsed overnight, and after hundreds of years, it could not escape the result of destruction. Afterwards, the four forces that destroyed Loulan successively established the four kingdoms of Linguo, Yiguo, Yeguo and Liguo.
He is the white-clothed prince Murong Jing who is admired by the world. He exists like a banished immortal and has the legend of being invincible. But after Loulan's demise, he never went to the battlefield.
She is Yun Jingxun, the ill-fated orphan of Loulan. Her family was destroyed when she was young, which created her premature and independent character. She experienced killings since she was a child, just to one day avenge the destruction of her country.
