As a rule I always keep my reviews as short as possible and try not to include many spoilers.

First if all, I recommend this to anyone who hasn't watched it yet, but be prepared for some heartbreak.

Visually this drama is stunning.

The music is absolutely beautiful.

The cast is impeccably chosen.

The female lead is a very interesting character. The difference between the innocent Xuan Ji and her powerful alter ego is so well acted that you don't even doubt it.

The eternally self sacrificing male lead whose name is mentioned so many times in the drama that you'll never forget it is an absolute delight to watch. The actor did such an amazing job that even a slight change in his gaze portrayed so much emotion it was hard to look away.

I absolutely loved all the secrets and twists. All the characters were interesting to follow. Even the villains were fun to watch. You keep wanting to see more. You keep wanting to know more and unravel all the mysteries.

All in all, this is a very entertaining watch.
