Ok, I think there were 8 different girls. Compared to numerous other stories and that one guy in real life that I think has 62 wives(definitely in the double digits, I could have accidentally doubled the number) I don't think the harem is so big that you have to die.
@awake1122 It is said in the title that following the path of pure yang means he'd die if he gets with a woman... meaning just 1 is too much for this man...
