I'm Really Not Mentally Ill!

Lu Yuanyuan accidentally enters a mental hospital, battles wits and courage with mental patients, survives there, and discovers abilities he has never had before. One day interview: Passerby A: Are you mentally ill? Lu Yuanyuan: I'm not, I'm just fighting with them. Passerby B: You had a lot of fun with them. Passerby A: You are a psychopath. Lu Yuanyuan: I... Not! Passerby B: You have gone out to hallucinate. Lu Yuanyao: I am saving the world! Passerby A: Look how sick you are, how pitiful~(ಥ_ಥ) Passerby B: Who says it's not? Lu Yuanyuan: I... Should probably... Not be mentally ill, right? Passerby A and Passerby B thought at the same time: I don't care if you are. It's so beautiful to think that one person's mouth can fight with two people!
