Reincarnate with Rimuru's powers!!

A terminal cancer patient after dying is in a white room with a shining man who offers him 3 wishes and he asks for all of Rimuru's powers. . . . . Note: I do not own Rimuru or Tensura or any of the novels or universes that appear through my OCs and if any of the creators of the characters or the image on my cover want it to be unsubscribed, it will be done.
