My Lord, the Demon Emperor Is Here Again.

She was originally the only god in the fantasy world. During the divine catastrophe that occurred once in a thousand years, she was plotted against her and was backfired, causing a wandering soul to travel to a different world in the 21st century. After twenty years there, I finally adapted to the living environment there, but now I was summoned back by a useless man without spiritual roots who activated the most ancient summoning array at the cost of my life. It's funny to say that she has always looked down on weak people without spiritual power, but now she was summoned by such a person with her life.
