So, I really tried to like this show. I mean, it has good actors, a splendid wardrobe, amazing production and special effects. Even the opening and ending OST match the vibe that this show is trying to achieve...

BUT:

1. The Gods are weaker than the Devils till the 46th episode
2. The secondary lead/Muguang is a complete and utter fool but also gets major screen time
3. The villain is known from episode 12 and continues to go undetected and run rampant till episode 46. AND you get to see this all the time as everyone else is taken for a ride but you still ought to believe that they are Gods and not idiots.
4. Only saving grace are another pair of secondary leads - TianQi and Gu Jun - who unfortunately do not get enough screen time or the power to solve anything
5. The ML is too busy falling in love/out of love/ reincarnating/ suffering amnesia/ solving reincarnation problems and acting like the entire universe 's problems are on his shoulders
6. One avatar of the FL which is all powerful and can actually solve problems is there in approx 22 episodes. The first 12 eps where she is busy training and falling in love (so in my eyes - basically doing nothing), and then the last ten where she alone is able to devise how to make good triumph over evil. The rest of her avatars are powerless and only involved in entangling with the ML and suffering in the hands of the villain

SO:

Story:
If you can't tell from the above points how frustrated I am with the overall pace of this story then my rant has fallen on deaf ears. The storyline is pretty interesting as it has been derived from a popular novel. All story arcs are also fleshed out sufficiently with multiple secondary leads. My only bone of contention is that this story will try your patience to the limit and then some.

Acting:
TianQi and Gu Jun were good. The female lead is a good actress and Xu Kai is good at looking good. To me the story overpowered the acting. I have zero tolerance for fools and characters that just don't take the hint. Unfortunately, this show is filled with them so I wasn't able to get past my frustration with the characters to appreciate their acting.

Overall:
This is watchable if you are a fan of xanxia/wuxia genre. The production value is fantastic and the special effects are truly wonderful. The acting is okay and if you are a fan of the book you'll probably be a fan of the show. I think I would have rated this higher if it was a K-show with only 16/24 episodes. If I am watching something for 49 episodes it had better be sensible and keep me invested in the characters. I lost hope after ep 40 and only sheer grit made me finish this show so I could share my review truthfully.
All in all, if you have low patience for issue resolution and do not suffer fools gladly then do not bother to watch. You will thank me later!

PS: This is my opinion. If you don't agree that's fine but please desist from writing rude comments.
