First of all, wuxia fiction is of course a fantasy. Although some story parts can be taken from real history, some martial arts can be taken from real life martial arts, some medicine and pressure points mentioned are real, etc., wuxia fiction is still a story after all, and while we may indulge ourselves in fantasy we *probably* expect some realistic aspects in the wuxia story we read.
In the past we have heard how HSDS was probably one of JY's works that really *begs* us to believe, like for example the presence of the bone healer medicine (what should I call it, actually?), how the gorilla didn't die after many years having the 9 Yang manual hidden inside his body, etc.
Let's take a look at another example. In DOMD, there was a fake Empress Dowager. She was a spy from the Divine Dragon Sect. She posed as the Empress Dowager for many years, while hiding the real Empress Dowager alive for those many years too, without being discovered. Okay, the part of posing as the Empress Dowager might not be too hard to believe, but how about that part of hiding the real one alive, and I cannot emphasize more that she did it for many years. How couldn't someone ever find out about it? What do you guys think? Do you think this part in DOMD possible, or is it another one that JY *begs* us to believe?
