Ah? Let Me Be the Demon Lord and Play Such a Big Role?

Thousands of years of floating dreams, the path of life and death. I am a demon, the common people bow their heads, and the whole world encourages me. I will become an immortal, destroy demons with my bare hands, and shake the heavens with my raised hands. That day, Lu Wei was sitting in a high hall and knocked on his forehead with his hand. He couldn't figure it out until his head was swollen: "What is my large password? Why can't I remember it?" "Eh? Who am I?" "Ah! I went to bed early because of my regular schedule and traveled through time!" —— I traveled through time and became a demon in a fantasy world. In this world, I promote the core values of socialism and engage in construction with the people. They all thought I had some ideological problems and was a big devil! ? That's outrageous! ! It's me who keeps everyone fed and clothed, and it's me who makes everyone's life rich! It is me who makes everyone live and work in peace and contentment! It's me... Um, no... Isn't the Demon Lord the biggest demon?
