Not very often, we've compared these two supremely fast and unconventional Gu Long swordsmen, but from what I recall, the consensus was that if Ah Fei from SENTIMENTAL SWORDSMAN, RUTHLESS SWORD dueled Sai Mun Chui Sheut from LUK SIU FUNG, Ah Fei would lose.
Are we certain about that? I guess that judgment comes from the fact that Ah Fei is a bit deficient in certain general martial arts skills such as inner power, acupoint sealing, and an actual hing gung technique, whereas Sai Mun Chui Sheut was a master of those arts as well as swordsmanship. However, in SSRS, Ah Fei proved many times that despite his lack of cultivation in certain aspects of martial arts, the swiftness of his sword could often overcome more "powerful" conventional martial artists.
Does Ah Fei really stand no chance?
