The 6 Mak Divine Swords skill was not featured in LOCH or ROCH, but there were two high-level 1 Yeung Finger Technique users in these two stories: Central Divinity Wong Chung Yeung and South Emperor Deun Chi Hing/1 Deng the Monk.
Wong Chung Yeung and Deun Chi Hing's inner power levels were greater than that of most 1 Yeung Finger users in DGSD (with the exception of Deun Yu). Did either Wong Chung Yeung or Deun Chi Hing/1 Deng have sufficient inner power to use 6 Mak Divine Swords had the technique been available to them?
