Although Xu Kai is more famous and holds the lead role as Li Xuan, I feel that Li Jun Chen aka Yu FengMu is the most handsome actor in this production (nice hairdo and costume). His eyes is mesmerizing and can convey micro expressions. He deserves more chances in a lead role.

Nice CGI effect when spiritual powers are being used. And the flying choreography is good.
The costumes and props and background is also beautiful. Other supporting characters needed more screentime and story development.

I like the song "If". It suits Yu FengMu's story in this drama.
