He was once the god in charge of memory. Because of a well-intentioned transgression, he was sentenced to eternal "possession" by heaven.
Of the thousands of faces, none of them belong to me; of the hundreds of lives, none of them can be retained. The cursed Thousand-faced Spirit "Shangyao" parasitizes the skin of a dying person in endless reincarnations to repay his obsession during life. It wasn't until a water spirit came to his door and a Ten Thousand Phase Stone appeared in the world that he realized that the curse thousands of years ago was not the end.
Intention: Find remembrance in forgetfulness, regain new life in loss
