I'm the Grim Reaper's child but I am barely surviving in a flooded world! (Oof)

Shi, A 24 year old person (because he has no gender like Death) was minding his business until one day "The Flooding" occurred where the world was flooded and most humans had evolved either into 3 different species or just stayed the same. 1.Drowns (people who died came back as monsters that vary in size color and deadliness) 2.mamalstorms (these are things like mammals to keep it short furrys) 3.Coldbloods (also furrys but like lizards and such) Please read I want to know that people read the story so I can make more:) !
