wait, so the author thinks that Crossbows didn't exist in the middle ages? Sure, in the early middle ages crossbows were bigger than that one, but it's still the same shape so the mercenary should've been able to understand what it was!
@Sancturil It depends on where and when this takes place. In Europe, crossbows didn't show up until 5th century, and even then they weren't really used until later. Other countries did have crossbow variants long before this though. Plus, this is another world. We can't really assume that they have the same exact technology advancements that our world had.
@Callidus That's my point though. The Middle Ages began around the 5th century CE, and based on what we see of the society and technology of the country in which this story is taking place, they aren't in the early Middle Ages, but instead seem to be at least around the half way point of the Middle Ages.
I swear the onii-chan somehow pulled an Isekai Tensei Soudouki and just hangs out in her mind. There are a lot of places where the onii-chan is just mirroring what she does.
If people assume they should apply our earth's tech to another world then i have news for you. Never assume every world has the same tech. And who says it's medieval era?
