The Ancient Tomb Sect's martial arts were devised by the sect's founder, Lam Chiu Ying, specifically to counter the Cheun Jen Sect martial arts of Central Divinity Wong Chung Yeung. Thus, although Lam never personally defeated Wong, her followers usually held the upper hand against Cheun Jen Sect acolytes (except in those rare cases when the Cheun Jen Sect member in question, such as Gok Dai Tung, was far superior in martial arts to the Ancient Tomb Sect member, such as Granny Sheun). The Ancient Tomb Sect's martial arts were the specific "black star" of the Cheun Jen Sect martial arts.
During ROCH, we did not get to see very many examples of the Ancient Tomb Sect's martial arts versus those of the other Greats'. The only such fights were brief skirmishes between Lee Mok Sau and assorted Peach Blossom Island personnel.
Do you believe that the Ancient Tomb Sect's martial arts have any significant advantage over the other Greats' martial arts such as Hong Lung 18 Palms, Dog Beating Stick Technique, Ha Mo Gung, 1 Yeung Finger Technique, etc.? Would Ancient Tomb Sect's martial arts face a better challenge from these other techniques to which the Ancient Tomb Sect's techniques are *not* the black star?
