Civilized Immortal Master

Well... Also known as Mou Qiangxian Master, I can kill you, do you believe it? "You traveled through time and became the heir to a rich man, and you have a pretty little maid?" Just when Su Bai felt that the time travel was okay, another memory popped up in his mind! "I am a detective who wants to find and arrest the murderer! In fact, I am an undercover agent!" Su Bai felt the danger, but unexpectedly a vague memory popped up in his mind! "I'm a death row prisoner???" Speaking of which, how can I break the memory of having inherited too many identities after traveling through time?
