The Number One Useless Good-for-Nothing

A peerless assassin of the 21st century was framed by a scumbag and died a wretched death. After transmigrating, she became a good-for-nothing, despised and looked down on by everyone. Worst of all, she was forced into marriage, only for her fiancé to bring his mother along to kill her, claiming she was a good-for-nothing who would ruin his future!!! Damn it, enough is enough! The peerless assassin takes over a good-for-nothing’s body and fights back against impossible odds, turning the world upside down. The phoenix shatters the heavens! Look down on me? I’ll beat your eyes out! Hurt my family? I’ll wipe out yours! You owe me? I’ll make sure your family is ruined and suffers for generations! You bully me? I’ll see to it that your line dies out and you never reincarnate! Heh heh, dare to laugh that no man wants me? I’ll show you what it looks like when a demon god from the nine heavens crashes my wedding to claim me! Say I’m too arrogant and domineering? Sorry, Long Ying is here to cheat her way to victory and torment people in this life!
