Hypothetical time.
Imagine that you're the Head Abbot of Shaolin around the time of DGSD (not necessarily Yeun Chi, but just someone in the position of Shaolin's top official). The Head Abbot of Dali's Celestial Dragon Temple comes visiting one day with a stunning proposition: he is offering the 6 Mak Divine Swords (including the initial 1 Yeung Finger component, so there won't be problems a la Deun Yu) to Shaolin in exchange for *either* the top six of Shaolin's 72 martial arts or the Yik Gun Ging.
As Head Abbot of Shaolin, do you make this deal? If you do, which one do you offer in exchange...the best six of the 72 arts, or the Yik Gun Ging?
