LIKES:
Costumes, colours, cinematography and locations, were all well done. Music was okay, but nothing memorable.
I loved the opening graphics of the little white "snake", it was super cute. First 2 or 3 episodes were good.
Inconstancy was a problem throughout. The FL doesn't initially save the "snake," it was her Lady that suggested it.
Second couple: Lonely Star and Blue Bird were the only reason I watch every episode of this garbage.
The actress playing the Blue Bird, was spot on even when in human form (constantly chattering away, very vain, always moving quickly from one place to the next, etc.)
All the reviews talking about the second couple are correct.
Plenty of immortal/magical moments as expected in a fantasy type drama.
Some of the special effects were good, but considering it's 2021 when it aired, it's pretty lame for the most part.
FX: the fireflies and wounds were well done, but the rest was cheesy or worse.
The cat demon's makeup was good and the actress is very pretty.
The hair for all the women was also well crafted, especially the cat ears.

DISLIKES:
WRITING
The writer started out with a good concept (pretty girl heals animals, they are demons and become loyal to her) and then the writer got drunk and wrecked the rest of the writing. And instead of calling the animals (both real and mystical) demons, it would have been better to call them spirts (good and evil) and why heavens immortals are friends with them. Too repetitive with the reincarnation lives, two maybe done well would have been plenty, but instead the writer muddles through multiple ones. Total crap. Even fairy tales have more kisses than this "romance" historical drama. Even the ending was stupid; just pick a concept already!
All they eat is pastries? Weird.
The "villain" is so obvious and gives a hint right in the beginning of the drama.
WAY TOO SLOW paced for the romance parts, thankfully there is fast forward.
Why start off making the FL a strong character and then trash all that over and over?
FX
The dragon's face when it became large looked like a cross between a fox and the dragon from Never Ending Story (American movie). The makeup and hair on the male lead was terribly done. The set design when it came to the rocks or rock formations was terrible. The fighting scenes, even with swords are not well choreographed and their swords look like rubber.
PRODUCTION
So many choppy parts, where editing was a fail. At least they didn't have shaky camera syndrome and used film stabilizer, but that's the only good thing about it. The CGI was terrible, as if their budget was limited, yet they made 36 episodes? UGH
Directing was bad too, huge lag when a character was supposed to react immediately, lack of showing the romance and chemistry, etc. Time management was a huge problem which was so obvious with how it dragged on.
ACTING
They did the best with what they were given. Dylan Wang was okay in this role, but they didn't direct him properly. Zhu Xu Dan was okay in the beginning, but became annoying later, but again I think this is due to the writer and director stuffing it up.
Deng Wei was surprisingly really good in his role as Lord of Luofeng Pavillion and showed good chemistry with Pan Mei Ye. Pan Mei Ye's acting was superb, especially acting bird like as her human/elf moments.

OVERALL it's a waste of time. The 2nd couple carried the drama, but still wasn't given enough time for a proper build of their chemistry and romance. I won't recommend it, unless you just watch a scene compilation on Youtube. I definitely won't rewatch.
