One day, Linghu Qiang suddenly acquired the "Villain's Revenge" system and began his new life as an isekai villain. His mission is to survive the story, claim his rewards, and return to his original world. But being a villain is no easy task. Sometimes, the protagonist would lock on to him right away and take him out. Other times, some mighty swordmaster would cut him down before he even did anything evil. In short, his success rate… kinda depends on his villainous skills.
