ZSF's martial arts were the start of a new theory in martial arts, 'start later, arrive first'. before that, all martial arts school were based on 'take initiative, move first'. even quanzhen sect which was a school with 'soft and empty' as it's basis followed the 'move first, seize initiative'. ZSF did have the idea of going against shaolin's martial arts idea so he won't be accused of stealing shaolin martial arts. he also took idea's from nature since he only knew about 22 moves. the shaolin 18 arhats boxing and four moves from yang guo's sad palms. most other schools would teach a few moves and then teach inner power cultivation methods. wudang started with inner power first, then moves.
