"On Zhong Nanshan, the tomb of the living dead" refers to the ancient tomb school in The Condor Heroes.
"Condor heroes, extinct rivers and lakes" should mean that Yang Guo and Miss Xiaolong later withdrew from rivers and lakes.
The woman in yellow should be a descendant or descendant of Yang Guo and the girl, not a daughter. Because when the little dragon girl was about 40 years old, Guo Xiang 16 years old. Zhang Sanfeng is a centenarian, and Guo Xiang is several years older than Zhang Sanfeng in "Eternal Dragon Slayer".
Judging from some subtle descriptions in "The Dragon Slayer", it should be the descendant of the great god carved Yang Longnv.
Chapter 33: The woman in yellow helped the descendants of the Beggars' Sect regain the position of leader when she first debuted, and then said to the elders of the Beggars' Sect, "My ancestors have a long history with your Sect."
Chapter 39 Secrets of the Art of War In this book, Zhang Wuji asked her name at that time, and she replied: "After Mount Zhongnan, the tomb of the living dead and the condor heroes disappeared from the rivers and lakes."
Readers who are familiar with "Heroes of the Condor" know that Yang Guo was instructed by Hong Qigong, the former leader of the Beggars' Sect, and learned all the formulas for beating dogs. Huang Rong, the next leader of the Beggars' Sect, adopted him as a child and taught him to read. Later, when Huang Rong fought against King Jinlun at Kistler, Professor Yang Guo learned the trick of beating a dog with a stick, so both Huang Rong and Hong Qigong should be regarded as teachers who taught Yang Guo. Yeluqi, the leader of Xiangyang Beggars' Sect, is also a good friend of Yang Guo. Therefore, the woman in yellow should say that her ancestors had a deep relationship with beggars' gangs.
[Condor Heroes] Finally, Yang Guo's little dragon girl decided to retire and return to the tomb of the living dead to spend the rest of her life. The woman in yellow doesn't have to say her name directly, but she inadvertently reveals her identity as a descendant of Yang Guo Xiaolong.
