Best wuxia fan theories ever?

[Ken Cheng]

Which theories devised by fans about wuxia fiction have you found the most interesting and plausible? These are ideas that the writers did not specify in their original texts, and have not commented on, but fans have speculated about.

Martial Arts Deterioration.

JY never explicitly states that martial artists from one era is weaker than another but from the feats performed by the characters, it does get less and less "impressive" as the timeline move forward.

There was one (not on this site) a while ago that my father told me about...

It claimed that Janitor Monk was actually the youngest martial sister of the XiaoYao Sect (younger sister of Li QiuShui). You know, the one that XiaoYaoZi really loved.
To escape from her martial sisters she hid inside the ShaoLin Temple for many years, and while she was there she honed her martial arts skills to perfection. However, she was always worried that someday somebody would (in a fight, of course) touch her or with palm wind lift her monk's robe (and thus reveal her true identity). So she practiced the "Qi Wall" thing to prevent such a possibility.

I myself don't believe it, but... I guess you have to give the creator of the theory credit for an awesome imagination...

I like the one that posits Kong Jian as being Guo PoLu in HSDS.

[odbayarb2000]

for me the plateau effect.

Kongjian = Guo Polu? That's new to me.

Yeah, Deterioration Theory comes to mind as a great one.

That Sweeper Monk = Li Qiushui's sister is my favorite unconventional speculation.

Others:
-Kenny's LDA theory for ranking fighters
-Huang Shang = gentleman who was injured by Dugu Qiubai

Also knew to me.
This would explain why Kongjian knew about the secret of the Dragon Sabre and Heaven Sword.

I would also like to add:

1) Ao Bai's dagger being made from the remnants of Dragon Sabre (aka Heavy Sword) in LDJ

2) Su Quan being a Gu Mu Pai member in LDJ

3) Hong Qigong's XiaoYaoYou being a set of techniques from XiaoYao Sect (aka from XuZhuZi)
