Thus, did the the venomous weaponry and skills that Lee Mok Sau became feared and renowned for in wulin originate from the Five Poisons Manual that she stole from West Poison Au Yeung Fung? Curiously, this could give her something in common with Yeung Gor: both used martial arts rooted in the legacies of Lam Chiu Ying and Au Yeung Fung.
Additionally, was the Five Poisons Manual ever mentioned in LOCH? It seemed like such a big deal in ROCH that if truly originated from Au Yeung Fung, it's surprising that it never came up during LOCH.
