The slime walked toward the wet sand area, he could sense Rem's soul energy coming from below and at once, the Slime knew that it was the boss room so he made a confident choice and changed the shape of his body, fitting to that of an adult man and continued walking through the wet sand… the magic stones jiggled in it's stomach and there was quite a lot of them, a rather obscene amount if one could see and all of that was gotten all in a day of being the prey.
'I should hide the Magic stones,' The slime thought as he reached the point where the sand started sinking him… covering it's stomach area with magical energy and concealing the magic stones, all he had to do was to sneak down and just get next to Rem, he was assured that Rem would do the rest.
