Where it all started

This is a story of Rimuru going back in time to become an Ancient Demon Lord like Guy - Milim- Ramiris.
In order to make this story interesting I will make "Rimuru" to have only a portion of his powers.

This story is inspired from @Mertinator1905 as he/she wasn't continuing it and mine will be different from theres but the base will be inspired from them.

This is my first fanfic so i hope you enjoy it and feel free to criticize it.
