The story mainly takes place in the four states of water, wind, earth and fire in the spiritual world; and revolves around the lords (wangjues)' fight for truth and honor.
The story line is good and is pretty consistent through out the series. The actors playing their characters good and I loved the brotherhood and chemistry between them. The make-up and costumes are fantastic. Unfortunately there are also a lot of director/-production flaws.. and the CGI, cinematography and music are average!
It's no masterpiece and probably a low budget production.
But I loved it <3
Just give it a try...You can watch it on iQIYI
