how the helly did he get a watergun from? can anybody make a theory about it

So gwen is from outside their isolated country and everywhere else is modern and advance except all is a fantasy world and only shah's country is backward because of their isolated lifestyle, hence the reason he commented that what Nain said sounded like a line from a movie

Hmmm I was thinking he was reincarnated rather than the rest o of the planet being modern

That's what I got from all what I read

probably a transmigrator

So I checked the novel info and apparently he's isekaid...my mad I was assuming wrong

Spoilers








Gwen is from the Labyrinth, a mage who is isekaied from different world. The story is related to the author's another story "Show me your stats!" but in a different country.
