Just before the end of LOCH, Gwok Jing and his archery teacher Jebeh engaged in one final archery duel. The result was a tie: either man could have made a legitimate claim to the title of world's greatest archer.
Both men sustained the same injuries (a serious, but non-lethal arrow penetration into the chest).
This seems like an unexpected result in light of the similar archery showdown between Gwok Jing and the Golden Wheel Monk many years later in ROCH. In that showdown, Gwok Jing managed to shatter the monk's arrow and bow with two arrows, then bring down the Mongol flag with a third.
Although Gwok Jing was not better than Jebeh in the archery department, at the end of LOCH, Gwok Jing's inner power (seventh best in the world after the five Greats and Kau Cheen Yan) was far superior to Jebeh's (none, except the natural inner power that keeps him alive). Although their skill levels were virtually identical, Gwok Jing's inner power should have enabled him to injure/kill Jebeh without sustaining injury himself.
Was Gwok Jing going easy on his archery teacher by not using inner power?
