I can't thank you enough for translating this on mangadex ! This is one my favourite thing to read ever. As Varler said, seeing this updated makes me so full of excitement~
Brothers are learning from all of the Association masters+dad while the sister is taking lessons from one of the five strongest masters in all of the magical land of China. So the reason why she was uninterested in learning the martial arts was because she already believed the old guy and was training under him (too dangerous to learn from more than one master). And here I thought he was sneaky about teaching her.
That and learning from multiple masters is not advised, hence it was such an issue with the brothers have multiple people's martial arts ki in them. The daughter is focused on learning from just one master, a master who is top 5 in the world.
@maraxusofk Y'all are missing something important. She's learning by watching, while being given the best foundations from the best of the best. She is observing how other people move, and learning just from that. She's being taught how to recognize something, utilize it and/or counter it, just by seeing it a couple times.
