I’m giving the drama a solid 9.
The story and plot is a mash up of multiple xanxia-verse so there isn’t much of an element of surprise on the plot but Cheng Yi oh boy Cheng Yi is a gem - His acting carried the show. The pain, anguish, regret and suffering portrayed looked sooooo real that I feel like Ying Yuan myself. He’s such an incredible actor that successfully made pain even more PAINFUL than it already is. I must commend that Yang Zi, despite her bubbly and girl next door image also did a fantastic job alongside Cheng Yi. The scene with her damaged and bleeding foot at the river destroyed me. Whyyyyyy??
The drama wouldn’t be as impactful without the stellar performance of our ML/FL. I think they’ve given all the characters justice.

What I love -
Brilliant first class acting by both leads!! We can hardly get performance like this anymore as they’re too many newbies in C-Ent and good looking actors/actresses without the real acting chops getting casted
The development from Ying Yuan and Yan Dan 1.0 vs 2.0 version of them - both have grown, mature and learn to love more u conditionally, so beautifully
The parallels between Ying Yuan & Tang Zhou/ young Yan Dan & demon Yan Dan - love how the tables were turned as they learnt the importance of living for yourself (for YY) and duty and responsibility (for YD)
The precious friendship between Yumo and the 2 Leads are beautiful to watch.
How Zhi Xi redeemed herself in the end - I love the twist to it
If you forget you have watched Eternal Love, Love and Redemption, the storyline is acceptable
Sexy Xuan Ye daddy is soooo sexy

The bad:
Some of the supporting cast - not exactly their fault but there’s so much repetition with some actors so it doesn’t feel as impactful. This is like watching Love and Redemption 2.0 in a way.
The editing could be better. Felt that the last few episodes were too rushed and could be laid out better for viewers
Too much focus on anguish and pain to a point it doesn’t make too sense - Yan Dan is willing to die for Ying Yuan, gave him her heart (literally and figuratively), suffered for 800 years but she’s not willing to be with Ying Yuan 2.0 just because he once chose duty over her. Err?? Like you’re already so in love with this person that you’d give him your life, why allow your ego to be in the way for smt so petty?
The 2nd ML - Yumo’s character is interesting and could have so much more potential if it was better casted. His acting is stiff and awkward which made whatever he does for Yan Dan very forgettable by the audiences.
