Oh boy I have a lot to say about this drama, and I invested my time worth of 59 episodes to watch this so I really do have A LOT to say on this.
First and foremost, the basic story is nice. Actually it is really good. Although I was tad creeped out by Xianji suddenly turning to a man and I was swept into a world of BL (which I totally like, only creeped out because I was not expecting it), the drama have a strong backstory. One could almost feel the pain the FL character went through in her past, (mainly because the star of mosha done a better job in acting than the god of war). And although I did feel sympathy for Si Feng, in the later episodes, the more he felt pain the more I found myself rolling my eyes, honestly is there any episode where he did not fell pain or was acting like a fool in love sacrificing himself, or comically jumping in front of the blade?

Summarized review (SPOILERS)

i) Slow and gradual process of love story. We can relate to the love story and it feels quite natural (as compared to Ashes of Love where everything seemed forced). However I personally find myself more moved by the 'sacrificing' part, probably because the ML sacrificed himself way too much that it lost the gravity, or perhaps the deliverance way not upto the mark. (or maybe I am still caught in the aftermath of Ashes of Love)

ii) The secondary characters were interesting in a way, and perhaps not so interesting in another. Honestly I did not care too much about Linglongs storyline, and her trauma really did not make any sense to me. I mean, it was the flower demon who did all that, and sure they are sharing same memories and all but why was she so affected by it? I found it rather bother than being sympathetic to be honest. Same goes for the Lize palace lords love story which rather feel stretched to be honest. But I think it might have contributed to the storyline and perhaps it was necessary but I found myself bored to the core. Now the storyline I found more interesting was of the fox and monkey, the fluff was just amazing. That reminded me, I really do not like silver snake and her death did not move me to tears sorry.

iii) The villains were... confusing. The deputy palace lord who never seems to die, dijun, who disappeared easily without any sort of punishment for all the things he done, and wu tong, for a mere mortal, dang, he did made the mighty demons run for their lives.

iv) The righteous sec leaders were just a no-no. They were harshly accusing someone with no evidence. Also arent they supposed to be kinda strong? But honestly the sec leaders felt really weak.

v) The final arch of the flask or torch or whatever that thing was tipping over to destroy the world??? Dear lord where did that come from???

Xuanji - At first she seems so childish, to an annoying level. Sure, its her naivety, so it can be pardoned. Her character development was steady, and it was sort of nice to see. However, the might of god of war was not that satisfying, in a way it made no sense? Sure she is the god of war but even the immortals cant stop her? Even when she is just a mortal? Now why is that just weird? Even with the misunderstandings, she stayed (or tried to) stay loyal to Si Feng, now that was satisfying (I am looking at you, Ashes of Love). Although she tried her best to portray the emotions, I rather felt it was fake when she did most of the time.

Sifeng - Apart from him spitting out blood all the time, and jumping in front of the blades to protect xuanji (probably because that god awful god of war armour was as useless as it seems), and sacrificing himself for love which he seems to be doing from the very beginning to the end, I really cannot understand his character. To say honestly, he really seems to lack a character outside the 'lost in love' thing. I was waiting for him to flutter his wings and show everyone that he was the son of the heavenly emperor and make everyone fall to their knees, but it never really came. It was like I waited all for nothing. Till the very end, his only character was to sacrifice and dot on Xuanji in a very toxic relationship which everything seems one sided if we look at it this way (but lucky for us its not because we know she was loyal to him) But I must say, him as the lord of Lize palace had me drooling. I mean im always drooling over him whenever he is not there spitting blood (which is like 90% of the time)

Linglong - Idk she annoys me.

Sixth senior - There was nothing much to say about him, although I found him and linglon lack chemistry and perhaps that was why the whole storyline felt dull.

I am lazy to go on about other characters.

It was a nice drama, although the story felt lacking in the later episodes, I dont regret watching it. The costumes were amazing, so was the setting. The CG was worthy to be praised. The supporting casts were amazing with their work. The OST was not that great, I expected something more. (lets blame Ashes of Love again). And the fluff was just heart eyes. but would I go back and watch it all over again? No.
