The only reason to watch this is because you saw the ML/FL in Love Better Than Immortality.

The story goes from mediocre to worse
The character development goes from bad to intolerable
The few good supporting characters goes from few to zero
Zhao Lusi's lovely voice gets dubbed & subpar at that

after ~20 the story just gets worse and worse. Obsessed people all turns evil over unattainable love as that's an excuse for bad drama

It could've been a great drama w/ the frame work. Magical land with CGI, fun magic powers, powerful healer with mysteries to be solved. Instead they focused entirely on evil obsession love.
Chu Tian Yao lives to be one the worst written characters ever in c-drama history. Completely unnecessary.
