Xuanhuan: Turns Out I’m a Cultivation Prodigy

My name is Wang Dachui... No, my name is Xu Changsheng. I'm the personal disciple of the leader of the Tianyuan Sect. Ever since I was little, I've made it my mission to uphold righteousness and punish evil, until I found out... I'm actually a good-for-nothing at cultivation! But that's not even the worst of it. A bunch of demonic-sect disciples are threatening to grind my bones to dust. I just want to ask, is it too late to call the police?
