Watched this series because of Zhao Lu Si and Li Hong Yi and see the high rating of 8+ (After I watch this I wonder how people rate this...) Hard core fans?

40 episodes is too much, 20 will be just nice. The story is very long winding, it's only about a love story with "conflict" in martial arts. Unnecessary episodes which at the end also does not make viewer want to see more.
Acting wise only main lead acting plus Liu Yi tong who portrayed Qin Liu Feng is good, the rest very unnatural.
First view episodes are ok, but then draggy until lost the essence of the story. So whoever looking at Zhao Lu Si drama, you may still watch this if you have nothing better to do and want to see her acting.
