The character Ah Fei from SENTIMENTAL SWORDSMAN, RUTHLESS SWORD is one of the most fascinating and charismatic characters in wuxia, but I wonder if the character's martial arts abilities make sense in light of what we know about how powerful wulin martial artists develop their skills.
To become a wulin elite, one must be a master in at least one of these areas: inner power, fighting technique, or hing gung. Typically, the best of the best in wulin will be a master in all of these areas.
Ah Fei didn't train in inner power. He had no hing gung or acupuncture sealing/unsealing skills. He didn't really have a sword technique per se. He was just superhumanly fast with his sword. And yet, Ah Fei was clearly among the best fighters in wulin. Only the likes of Seung Gwoon Gum Hung, Lee Chum Foon, and Old Man Sheun were clearly superior to him.
Could Ah Fei really reach that high a level in wulin without inner power, hing gung, an actual sword technique (not just being fast), etc.? His speed was able to make up for the fact that he was missing two or three of the key components for attaining elite levels in martial arts?
