DROPED. This is a story about a guy who died and went isekai. While the characters may sometimes may seem too crazy, they are simply that, crazy. There is an actual way to do everything in this novel, may it be turning into a God, whatever the fuck is above that protect me from ever having a destiny like that, or conjuring a fire ball, and those are all explained during the novel. Some things are basic, like earth magic is stronger underground, or the law of equal exchange, but everything is explained at it's own time. Also on Webnovel.
