It's a given that in wuxia, regular soldiers/archers shooting arrows at Greats-level fighters are basically wasting their armaments/effort/time, because 99% of the time, those arrows have no chance of actually hitting their targets. It's almost too easy for a Great to dodge, deflect, or even throw back incoming arrows shot at them by ordinary archers.
Strangely, Chow Bak Tung, who might have been one of the top three fighters in the world at the end of ROCH, was injured by the arrows of Mongol archers in one of the final chapters of story. Somehow, after having defeated powerful foe after powerful foe for decades without sustaining significant injury, Chow Bak Tung was somewhat seriously wounded by the arrows of mere soldiers. How could this have happened? And why did it happen only to him and not Wong Yung and 1 Deng, who were with him at the time?
