I think I've read this in qi before, it's about a guy who is in or can go to a medieval world and he sells them guns and things. If you know the tittle please comment bellow. As for why I used the recomedation tag because if you have any other similar story please comment. So basically I want a weapons merchant as the mc, it would be better if it's like selling them weapons like guns to a society that uses magic or swords. Thanks
