Review Detail of Kjv_Kjv in Child from the Dungeon

You need to give us a proper world background author, otherwise, we wouldn't understand where and when the story takes place. By the way, I begin to notice that the story had similarities with My Solo Revenge. Is this story happening in the same universe as it? or (based on the My Solo Revenge's lore), does this tory happens in one of its Timelines?
