The story is what kept me going in the first season. I was really annoyed by Duan Mu Cui's personality, mostly when she starts falling in love, and I couldn't deal with Darren Chen playing Zhan Yan. I saw him in The Sleuth of Ming Dynasty and that's all I could see him as during the first season; he didn't fit the character of a constable. So when they fell in love, it just didn't work for me; there was no chemistry in my opinion. However, towards the end of season 1 and mostly during season 2, I feel like their chemistry got better and it was more believable.

The story is somewhat unique. Humans and immortals fighting demons/evil, solving crimes, falling in love (nothing new); travelling to Shen Yuan (aka "The Abyss") was something new to me, and probably my favorite part. You get to see a different side to Duan Mu Cui and see what she was like; I really enjoyed it.

I really don't know what to say about Zhan Yan. He's what you expect his character to be like: righteous and loyal. There's not much development in his character, which makes sense since the drama is basically about Duan Mu Cui.

I just feel sorry for Wen Gu and Hong Lan's characters. They are just so tragic in my opinion (oh, unrequited love...the bane of all dramas). I loved Yang Jian as Duan Mu Cui's brother. He's serious and funny. He cares about his sister the most, and does everything he can to protect her and make her happy. And lastly, I can understand Jiang Wen Qing because seriously, why was everything left to Duan Mu Cui to deal with?

Anyways, overall I liked this drama. I'm glad I stuck it through the first season because the characters really annoyed me, but the story was interesting enough for me to keep going. And I'm glad I did because it got better.
