This drama deserves more promotion than it got. I really wanted a Zang Linghe-Esther Yu pairing after Love Between Fairy and Devil. I am glad that I finally got to watch them together as lovers.

The story is about Yun Weishan, a Wufeng spy who needs to do one last risky mission before she can gain her freedom. She must infiltrate the Gong Residence, a fortress that Wufeng needs to crush to entirely rule the martial arts world. There, she met Gong Ziyu, the degenerate son of the Gong family and the man she thinks she can use to complete her mission. But what will happen if a spy falls for her target? Then it can only end in tragedy.

The story is full of intrigues that keeps you guessing what's next. Add a capable cast then you'll have a good drama. I really like that Esther Yu as Weishan was able to prove in this role that she can play a serious and badass character. It is so far out from the cutesy and bubbly characters like Xiao Lanhua that she did in the past. I know she can do it and I'm glad to be proven right. Zang Linghe as Gong Ziyu was not as amazing as she was but he was able to passably show the transformation of a weak character into a strong leader. The second leads, Lu Yu Xiao as Shangguan Qian (another Wufeng spy) and Ryan Cheng as Gong Shangjue (Gong Ziyu's rival for the Sword Wielder position), had one of the most edgy relationships I have seen in a while. They always have the "love each other-just use each other" air between them. Both of them gave microexpressions that kept you guessing their true intentions. For the supporting roles, I always looked forward to seeing Omid as Han Yasi (Weishan's trainer), he's kind but have to be tough. I also have to mention that Tian Jia Ru as Gong Yuanzi (Shangjue's foster brother) gave me complicated feelings. He was so hateful and maniacally crazy when he was planning bad things against Ziyu but so lovable when he's being a puppy to Shangjue. I didn't like Gong Zishang (Ziyu's cousin played by Jolin Jin) that much, especially when they use her for comedy. I sometimes find her annoying when she's running after men and when she's being screechy, but she's ok in non-comedic scenes. All the remaining casts were also good. Questions that I had for some illogical things that happened were given explanations.

But, and it is a big but, the writers did not give a perfect happy ending. They used the last 5 minutes to give a cliffhanger ending, maybe so they can have room for a season 2. So if you want everything in a bow, don't watch the last 5 minutes. Otherwise, this was a great drama.
