That time I got reincarnated as a slime--Rimuru x op reader

Since I have ever seen one story about someone different go the rimurus demension. I decide that I would start my own fan fiction.

This one starts off with rimuru in the cave talking to veldora. And veldora senses a very powerful magic more powerful than his and he says for rimuru to hide and something grabs him before he can hide and you have to read the story.
