I was watching clips of HSDS03
In the novel, while trapped in the cave with XC, when CMK tried to use 9 Yang to open the wall (pre learning QKDNY), did XC know what martial arts he used? If so, how the heck did she know he was using 9 Yang.
When CMK used QKDNY, Yang Xiao and MK's grandfather seem to realize that CMK is using QKDNY. Is that possible? CMK has reached a peak that no one in the lifetime had seen before, so how do they know what he is using.
Yang Xiao only learned up to part two. Does he know the rest of QKDNY then, just that he is unable to learn it?
Does each level of QKDNY allows you do some special ability, but just because you know what it does, not necessarily mean you can do it?
Hence Yang Xiao only on level two, but he can recognize CMK being able to at least accomplish level 6.
