The story line was really interesting and I really enjoyed watching it, but I wouldn't say that it's a must watch or one of my favourite drama. There were many scenes and details that could have been more elaborated as there were some scenes that felt kind of lacking and others just weren't that well explained. The acting was okay, not the best not the worst. Some characters were super annoying but I did like the personal growth of some of them like Princess Chang Le or Mu BeiYan. Personally, I got hooked once I started watching it and kinda ended up binge watching it. I'm a big fan of strong female leads who know how to fight and don't need a ml to protect them so that's a huge plus in this drama. The mysteries and murder cases were really well thought and I love how the solved the cases. Although I do enjoy dramas and misunderstandings to spice things up, the lack of communication from the ml drove me crazy and it ended up being a bit annoying how he took the fl for granted and how he tried to plan her life without consulting her. The ending also felt too rushed and I feel that some characters deserved a little bit more of screen time and background story to at least relate to them a bit better. For example, the background story of Yanxi and Jiang Tan, and how she ended up working for the enemy would have been interesting. All in all, it's a nice costume drama and I really enjoyed the plot.
