There are two well-known fights in wuxia that were preceded by the main participant's use of inner power to heal another, and I wonder if in either case, the performance of the participant during the fight was affected in any meaningful way.
The first is Gwok Jing during ROCH. Two nights before facing the Golden Wheel Monk, Wan Hak Sai, Siu Seung Tze, Lui Mor Singh, and Ma Gwong Jor outside of Kublai Khan's base camp, Gwok Jing had expended some of his inner power to correct a "fire deviation" that he believed Yeung Gor had suffered. Did this affect Gwok Jing in his battle against the Mongol mercenaries in any noticeable way?
The second is Sai Mun Chui Sheut during the duel. Again, about two nights before his duel with Yip Goo Sing, he had used his inner power to heal Au Yeung Ching after she had been stricken by a Tong Family poison dart. Did this contribute to his relative slowness during his duel with Yip Goo Sing?
