These big shots are actually me

I traveled through time to a backward world without magic, fighting spirit, or even electricity. It’s still a standard orphan start.
Fortunately, time travel has given me a relatively comforting benefit, that is, I can experience various fantasy lives in my dreams.
In my dreams, I was one of the ancient gods, leading a noble rebellion against the original.
In the dream, I was the most authoritative Grand Duke of the ancient empire, and I single-handedly created this great empire.
In the dream, I was the most powerful hero in the mythical age, and all evil was afraid of me.
In the dream, I was the leader of the elves, the oldest king who guarded the twin sacred trees.
In the dream, I was the girl’s god, but I played a big joke on her.
…..
My traces and legends can be found in every era, but no one knows that these famous people are all one person!
And now you suddenly tell me that it was not a dream, it was real? ? ?
And so many goddesses, saints, princesses, queens, etc. that I provoked are still alive? ? ?
