Slime Paradox

Let's go back to the timeline where Rimuru never became a demon lord but an awakened demon lord only

After Rimuru sends Chronoa in the past as a time spirit while the war between the East and the West is currently happening

Rimuru was about to die from using too much magicules after he managed to send Chronoa to the past which will cost his life and since he already used all of his magicules from trying to calm the rampaging Chronoa.

But before death comes to him, all the sudden he found himself in a place where the time doesn't moves on which prevents him from dying, a place outside from the Cardinal world.

There he watched Chloe's time travel adventures through a pixilated screen and decided to help her from behind the scenes with the help of his trusted partner

This story is inspired by Aftertale, an Undertale AU (my favourite) made by CrayonQueen/Loveofpiggies
