I Am a Villain in the End of the Law

"Dedicated villain" and "forced to move". In order to survive, the protagonist has to follow the script to grab treasures and kill Zhengdao, but every "evil thing" he does is actually to slap the hypocritical Zhengdao in the face, or to help the low-level monks in disguise. The more seriously he played the villain, the more the protagonists (especially the heroine) felt that he was deep, lonely, and unable to control themselves, and in the end they were really impressed by his charisma.
