You don't need the JIETAI or the power of HIKKINEET to subdue 3rd-world fantasy realms. All you need is... cola! They'll all drop dead from diabetes in a generation. Then you can farm the dungeons yourself. This strategy is especially effective when dealing with parallel world isekai where there is plausible deniability that you didn't genocide the parallel world(s) you just genocided for fun and profit!
@valconius cola on its own won't be enough. A Wacdonald's franchise smack in the middle of their capital city would provide the required junk food firepower needed for total subjugation. 👽
Haha, has elf hentai manga, I wonder what an elf would think of such a thing. Also wonder if he has anything involving female knights going "k-kill me".
