That is precisely what happened. Except this happened with both his weapon style and bare handed style.Originally Posted by Ken Cheng
With a barehanded style it's not unusual since a weapon gives an advantage. Martial arts master can determine who's better without resorting to weapons, but that doesn't mean a weapon isn't an advantage.
With the sword, YG made a severe error in believing that he had enough internal energy and internal energy control to be able to use the wooden sword against an equal expert.
