According to an offhand remark made by Cheung Mo Gei in HSDS, the Ming Cult had been a presence in the Chinese wulin for centuries by the Yuan Dynasty. We know for certain that the Ming Cult had been present in China at least as far back as the period between DGSD and LOCH (Chow Bak Tung told Gwok Jing about the entire incident between the Ming Cult and Wong Seung that led to the creation of the 9 Yum Jen Ging), and it probably even predated the era of DGSD.
Oddly, we hear *nothing* about the Ming Cult until HSDS other than Chow Bak Tung's discussion with Gwok Jing on Peach Blossom Island during LOCH. During the LOCH/ROCH era, this is understandable because the cult was likely still recovering from its devastating encounter with Wong Seung, but what about the DGSD era and earlier? Just one of many questions:
1. What was the Ming Cult doing before and during the era of DGSD? It was supposed to have been a major wulin power for centuries (Cheung Mo Gei compared the Ming Cult to Shaolin Temple and the Beggar's Union for longevity and influence), but the Ming Cult was never even mentioned in DGSD.
2. Other than Chow Bak Tung and Gwok Jing, did anyone else alive during the era of L/ROCH know about the existence of the Ming Cult? The cult had apparently gone underground during the decades after its near destruction at Wong Seung's hands, but was it even marginally involved in wulin at the time? Could Ming Cult members have secretly been part of Gwok Jing's Seung Yeung defense force or Yeung Gor's group of allies in ROCH?
3. Sometime after ROCH and before HSDS proper began, the Ming Cult once again emerged as an important presence in wulin. When did this happen? It was before the main story of HSDS began, but how much earlier? Did the Ming Cult's resurgence happen closer to the end of ROCH or closer to the beginning of HSDS?
4. It was to defeat the Ming Cult that Wong Seung created the 9 Yum Jen Ging. If so, it would only make sense that Wong Seung needed to defeat the Ming Cult's most powerful martial art...the Keen Kwun Dai Loi Yee. Was the 9 Yum Jen Ging primarily designed to counter the Keen Kwun Dai Loi Yee?
Ironically, although Wong Seung himself never got the opportunity to use the 9 Yum Jen Ging against members of the Ming Cult, some 200 years later, a portion (the 9 Yum White Bone Claws) of his martial arts manual would indeed be used against a Ming Cult leader (Cheung Mo Gei).
