This is the only drama that I've watched three times. That's how much I loved it. But I'll keep my review simple and easy to read, instead of reading long paragraphs.

+1 Amazing Cast (No one can play a better Yehua)
+1 Beautiful & Befitting Music (music really set the tone/stage for this drama, went along with the theme, plot, and brought out the story altogether, without the music, or music in general, it would be hard to make successful dramas, good music is what draws people emotions and imaginations)
+1 Romance Action (more like +100, at first you're like where's all the real action? Just wait and keep watching, you WON'T be disappointed. Trust me on this one. It'll creep up on you and surprise you out of nowhere)
+1 Beautiful & Eloquent Clothes Set
+1 Strong, Creative and Complex Story Plot
+1 Set (pretty good for a fantasy drama for the most part)
+1 Relationship Build
+1 Character Build (except for the relationship between Moyuan and Siyin. It kind of came out of no where, like what? huh? They had a close mentor/mentee relationship? Didn't see that but since everyone said so then okay...)
+1 Strong Side Character Stories (Feng Qiu's side story was kind of redundant and annoying but they made the story interesting and impactful at the end)
+1 Good Ending

Cons?
- Fighting action could have been better and "floating/flying" scenes were average and very noticeable
- Like most dramas in general, some dragging parts that take forever with your typical mellow characters, but the story eventually picks itself up. Can't avoid that one.
-Some people will have a hard time liking the male lead at first but don't worry, he'll draw you in when you least expect it.
