Review Detail of Shadow_king_393 in God Of Monsters System

i just want a good long live summons with system because I think my writing isn't good enough to write one but i think yours is a good story just don't drop it if you need a second world you can use a world like high school dxd because one fact it's popular and has alot of things in its plot , you can use another world like harry potter you can use it to get some mind magic , my hero academy to get a quirk and others alot
