in the novel, the Ming Cult's 6 fighters didn't have some type of uber fighting formation did they?
cuz i recall in an old Jin Yong rpg game i played in the past, they did have such a formation but i'm guessing it's just a imaginative alteration the game designers just had to put in.
So what if they didn't have an uber formation? The Ming cult got so big; it would blow my mind if the 4 Guardian Lords never fought together. It makes zero sense if YX and FY never fought together. They were known as Xiao Yao Er Xian after all.
