66 episodes that I thought I will enjoy because I love all Dee Renjie works however, this dragged for me.
It may be because I have seen all the recent Dee Renjie works that this click for me. The story was slow and the romance added seemed forced. I may be biased because I prefer mystery without an added romance. There was more chemistry between renjie and the empress than the female healer that us supposedly his love interest.
The character of Dee Renjie here seems off from the typical Dee Renjie character played.
