Isn’t it normally the isekaid persons job to know things like cooking (and drone on about umami lol), rather than the slave that’s been in a cage but can apparently fight and cook, I repeat he was a caged slave in a medieval time period.
I think someone said the peace won’t last but I’m not too sure, they didn’t even get assaulted by bandits this time lol. I think this is just aiming to be a nice pleasant story.
