I would guess that she was originally a character from one of the worlds (like the type she migrates to and helps to avenge). It hinted at this a lot in the cultivation arc with the weird sect master who was obsessed with her. Basically, (I assume) characters who are very smart and realize that their world isn't all their is to the universe have a chance to become like Su Luxia
Do you think the reason why she's helping those female characters out is because she's trying to find out a way to defeat someone from the world that she came from.
I don't know actually. I would think that she already kicked eveyones' ass in her story already. but your guess is as good as mine. it's weird bc her name is Su Luxia and so is all the other females that she has helped, so i could see your theory working.
It's mentioned that the name 'Su Luxia' for all the female leads she's transmigrated into is for convenience sake so nothing deep about that.
In the other side story, where she first starts out as a transmigrator, it's mentioned that she was a cannon fodder that died in her own world but was given another chance to be a transmigrator.
I cannot wait to find out who is Su Lüxia really is. Since they don't give out a lot of information about her and her life since it is classified. Since this manga has romance in it. I would always wondered who is Su Lüxia going to end up with. And why does she always help female characters who has been treated bad by others?
