When she is there (when the father died) i had a feeling fu ling is bai xi. That's jst my guess
Now I'm pretty sure she is a xi or bai xi. Coz in ep 17 her master told that her family abounded her he was the one saved her and a'xi was also dying and was gone from family. So he the master could hav jst manuplate her
This one is just burning man, it's so good. Only watched 3 episodes and I'm sure it will be one of the top drama. The plot the characters the ost everything is on point
