About the question on how the fuck a goblin that has the lifespan of a week able to form societies, it probably has something to do with their transfer skill thingy, and the skill every goblin has the moment they are born and the fact that they're extremely fertile, meaning there probably is an abundance in their population and also that it's fiction, so expect things to not make sense. And I wouldn't say this is pretty shit if I just read one chapter, I'd give it a few chapters more and decide from then. And yes, I understand it has a resemblance to the first chapter of tensei shitara slime datta ken but I won't base my judgment on the story from there, the author probably got inspiration from there or didn't have any other idea to start their story and is greatly invested in the idea of the mode of isekai in tensei shitara datta ken. Point is, there are tons of isekai out there, it's kind of hard to be original in the start of the story, hell, I cant even count the many times truck-kun has been responsible for many isekai incidents but still, those stories differ, and that's what matter.
