To his dying day, Beggar's Union Chief Lo Yau Gerk never became one of wulin's top fighters. The man had heart, but his martial arts were mediocre. In the world of ROCH, it's doubtful that he broke into the top 25 martial artists of the period.
Surprisingly, however, he held his own during the assault on Seung Yeung Fortress after Gwok Jing was injured by the Golden Wheel Monk and the other Mongol mercenaries. With Gwok Jing incapacitated, Wong Yung in labor, and Yeung Gor and Little Dragon Girl already having their hands full fighting the Golden Wheel Monk, it was up to Lo Yau Gerk to singlehandedly hold off Siu Seung Tze, Lui Mor Singh, Fok Do, and Dat Yee Ba. Fok Do was the weakest member of that group, but he'd already handily defeated Lo Yau Gerk during the Luk Family Manor Heroes Conference. Somehow, however, Lo Yau Gerk was able to hold off those four superior fighters without getting killed or seriously wounded until help arrived (in the form of the Fisherman and Mo 3 Tung). How was Lo able to put up such a good fight against such powerful opposition?
