During the Second Mt. Hua Sword Tournament near the end of LOCH, Wong Yung arranged to have her father East Heretic Wong Yerk See and her teacher North Beggar Hung 7 Gung fight Gwok Jing instead of each other directly to ensure a fair fight (mitigating such factors as Hung 7 Gung's recent recovery from a two-year period of injury, a very recent fight against West Poison Au Yeung Fung that had sapped some of Hung 7 Gung's energy, and the fact that Hung 7 Gung had practiced some of the 9 Yum Jen Ging while Wong Yerk See had not). Inadvertently, however, could this arrangement have actually saved the two Greats' lives?
We saw what happened on Mt. Hua during ROCH when Hung 7 Gung and Au Yeung Fung went all out against each other directly; both lost their lives. Their egos prevented them from giving anything less than their all to defeat the other.
Had Wong Yerk See and Hung 7 Gung fought each other directly during the Second Mt. Hua Sword Tournament (taking away Hung 7 Gung's various disadvantages due to injury and advantages due to the 9 Yum Jen Ging), would they have ended up killing each other as Hung 7 Gung and Au Yeung Fung indeed did some seventeen or eighteen years later? Did fighting Gwok Jing, against whom they had to hold back (for fear of killing him), actually save them from a potentially lethal duel against each other?
