I have a few negative things to say, and I will say them first.
✘ Regarding the male lead:
In the beginning, we get an overpowered villain male lead with deadly ancient powers. He could basically destroy entire realms and no one could stop him. He is ruthless, emotionless, and deadly. Now I'm a sucker for overpowered anti-heroes so the premise was right up my alley. I love it when shows don't just hype up someone, but also DELIVER. In this aspect, the show delivered in episode 9 (my fave episode in the entire show) and then never again. It got me sooo hyped up, but then it fell through. The hero becomes more of a hero than a villain, he becomes emotional and weak. He completely changes his cold and ruthless demeanor I loved. I am okay with having him gain emotions and falling in love as a part of his character development, but I really hated him becoming as weak as any other immortal. He gains his powers back in the very end, but we get to see nothing of it. :(((

✘ Regarding the ending:
The ending was very rushed. The angst that began with him losing his powers and the heroine dying continues up to the last few seconds of the show. The hero returns, they kiss, and the end. We see nothing more of the goddess/Orchid mix of a character. I'm still not sure how that works. We get robbed of seeing him in his overpowered state again and reuniting with his people and others. We see nothing of how others react to him coming back. We don't even get the wedding. I feel like the price we paid with all the angst and heartbreak wasn't worth the 3 seconds of HEA.

That being said... I LOVED everything else.
❥ The whole show was soooo AESTHETICALLY PLEASING, I can't stress this enough:
The cinematography was stunning. The intro and outro art was really something else, just absolutely gorgeous. I absolutely loved the costumes, especially Moon Supreme's armor. The soundtracks are amazing, especially the main theme/opening song (Cut Off Love (诀爱 Jue ai)) - I'm still listening to it now after the show ended, it gives me goosebumps and possibly PTSD to all the emotional scenes, lol.

❥ Some scenes were so EMOTIONAL, they made me cry:
The father-son scenes really opened an important theme of sacrifice. Heroine's sacrifice was gut-wrenching. And finally, the hero's sacrifice probably hit the most, because I really felt he was gonna disappear forever.

❥ The show was really FUNNY too, especially in the beginning! It had so many comic relief scenes that really made you cringe-laugh all the time.

TL;DR: get ready to laugh, cry, have PTSD from this. 10/10, worth rewatching and worth sticking with 36 episodes.
