EDIT (putting it at top so you don't gotta read my confused rant lol): Okay, so I did all my research. Jia is from what is known as a Murim (the Korean equivalent of Wulin), which is a "martial arts world" used in the Wuxia genre (a genre focusing on the stories of martial arts/martial artists); it seems like the genre is traditionally Chinese but also used in Korea. The world is basically the same and all Chinese-geared, but generally with Korean names. So Jia is not from the same world as Valerie at all. She's not from ancient China and happens to know martial arts but is actually from a fictional martial arts world, hence her martial arts abilities also including magic. In her world, there are SOME people with non-martial arts powers;. This part I'm not so sure of, but it sounds like they're referred to as being in a clan but aren't actually related. The source of their abilities is not common knowledge. As for why Jia introducing herself as "Moyong Jia" made Valerie realize she was from Murim, this is because the Moyong family is a prominent one in Murim (I guess the world in all the stories has basic stuff like the same Noble families?).
As for why Valerie could read a Chinese character... idk. The fact that she's so familiar with all this, I can only imagine she was a fan of, or at least familiar with, the genre.
----- Some of this is so confusing that I’m not even going to try and understand it, but I just wanna get this basic thing down.
At first I was just like “Oh Jia’s from ancient China” but then there was the flying stuff. Then suddenly people from her world have powers. And apparently reincarnation is common enough that they call people like that blood sect (unless I’m misinterpreting which I probably am). That’s definitely not ancient China lol. I mean, I was confused why Valerie knew a Chinese character, especially when she said she was Korean. So why does Valerie seem to know so much about Jia’s world when it is very clear that Jia is from a different world and Valerie is from our world?
