She makes it to the list after
defeating the younger 金輪法王. With 玉女素心劍法 plus 左右互搏, she became one of the best
defensive fighters. 金庸 often says that her inner power is weak, but that is one of several inconsistencies he made in the story. She had been sleeping in the 寒冰床 for at least five years, and it was supposed to help increase her inner power improvement by a factor of 10, so her actual inner power should be a lot higher than what 金庸 had made it to be.
