This is a very good and entertaining period drama. This drama has a lot of well choreographed action scenes, crime investigation, palace antics, a great antagonists and his entourage of bad people, a loud, oftentimes too impulsive but sweet and cute female lead, and a seemingly cold, smart, and loyal male lead. The supporting cast was great and the main cast was fantastic. The female lead, Yuan Jin Xia ((played by Tan Songyun) and imperial officer Lu Yi (played by Ren Jia Lun), had great onscreen chemistry, which left a hint of disappointment that their love storyline didn’t have many romantic scenes. The romance takes places slowly, it is steadfast and endearing as they both are constantly working together and willing to sacrifice their own lives to protect the other, and for the lack of romantic scenes, they make up by their understanding just on the way that they look at each other! Overall, this drama has adventure, mystery, action, and a lovely romance. Enjoy it!
