It's actually 43 episodes.

I give this show a 10 to contribute to raising its rating, it certainly deserves more than a 7.9. At least 8.2 at a minimum. I've watched an 8.7 (One and Only) & an 8.9 (Love Like The Galaxy) that were down-right boring compared to this.

I read in another review it's a "refreshing take on xianxia" and I agree. The two leading characters are mortal, which makes a change for a xianxia, and makes their time all the more precious (as well as their sacrifices). The story, too, is refreshing in it's way and full of suspense. The disciple-master relationship developing into something romantic is nothing new but this one seems different.

Zhu Yan has some very satisfying character development from her childish younger self and a good deal of independence. Shi Ying is the seemingly aloof master while still being very in-touch with his emotional side. And Zhi Yuan is the selfless, gentle but powerful third lead who carried half the show. His character is so endearing you never tire of seeing him, with a sprinkle of Chong Ming to keep things lively.

The story starts a little cliche but gets a lot better later on and becomes something to be truly invested in and enchanted by. The ending was a little rushed and some explanation was lacking, but the final fight was a pleasant suprise as the show goes into full xianxia mode.

My only qualm is that Ren Min and Xiao Zhan sometimes failed to convey strong-enough emotion in their expressions for the circumstances they were in. But I love the whole cast, Alen Feng was a favourite in this one and it's great to see Xiao Zhan in a fantasy show again. I only give the rewatch value a 6.5 because a lot of what holds you in on this show is the suspense which is gone on a rewatch.
