Jiang Yun died in his original world, and his spirit traveled to a cultivation world as the Holy Son of the Sacred Land of Mist. However, his new body was severely injured from being attacked by demonic cultivators and having his Sacred Bones stolen.As he was in despair, a voice from a System, known as the Villain System, sounded.
