I love Wuxia dramas. I think my introduction to Wuxia dramas was Legend of Fu Yao. I gave it a watching the plot sounded interested. I've been a fan ever since.
This drama started off very well, but I dropped when it got to the backstory with the mistresses. I also just couldn't get past that creepy incestious relationship the doctor had with his stepmother.
BTW your comment has bit of a spoiler, so I think putting that in a spoiler would be a good idea
