This drama's thrilling opening had me on the edge of my seat with my heart in my throat. It is one helluva start that brilliantly sets the stage for the backstory. We are immediately transported to ancient Wei, a wicked, immoral, debauched kingdom where the dissipated nobility hunt slaves for sport. Our titular character Xing'er/Chu Qiao is no ordinary slave she is a superhero; assassin, gladiator, warrior and survivor. Her courage and fiery fighting spirit draws the interest of many suitors including her owner and spymaster Yuwen Yue, Yanbei hostage prince Yan Xun, Prince Yuan Song of Wei and Prince Xiao Ce of Liang. If not for the fact that she pulls her weight when it comes to the rescuing, this would sound absurdly Mary Sue. As it turns out, the most powerful men across three rival kingdoms simply have a death wish and are fatally attracted to dangerous, irascible and bad-ass women. Recognising her indomitable spirit and lethal fighting ability, Yuwen Yue trains her to be a top notch spy and assassin.

I enjoyed every moment of the first half of this drama - despite some discontinuity in the editing, the plot is intriguing, the characters are flawed and complex, it moves at a fast pace and the fight scenes are powerful and exhilirating. The chemistry between Zhao Liying and Lin Gengxin is off the charts and their supercharged one on one fight scenes are hot, hot, hot. The way Yuwen Yue grooms her, her gratitude and resentment and the push and pull attraction between them and their strong personalities results in a highly combustible build-up in passion between them. I just love how his eyes reveal how vulnerable he is, his grumpy sullen glower conveys his displeasure at being enslaved by his slave while the tiniest wry smile suggests a sense of acceptance and humor about it. The fierce answering spark in Xing'er's fiery eyes and her combative, resentful stance is a dead giveaway as to who this spitfire also most unwillingly longs for. I believe she would never have left with Yan Xun if her pride had not been so wounded at the thought she was nothing more than a lean mean killing machine to Yuwen Yue.

I have always considered Zhao Liying a vastly overrated, creepy life sized LOL doll with her gigantic head and eyes. This drama has given me a newfound appreciation for her acting skills and commanding screen presence. Her fight scenes are phenomenal and it is obvious that she immersed herself in this fabulous, kick-ass role of a fearless heroine with a big heart and bold dreams. It is hard to pull off the typical cold male lead well but Lin Gengxin effortlessly depicts the iceberg that conceals a dormant volcano. It is such a waste that his masterful articulation of such a complex and interesting character does not get nearly enough screen time. With one glaring weak link, this boasts an all star cast with complex, interesting and funny supporting characters with Xiao Ce (Deng Lun), Yue Qi and Yang Song being my favourites.

After peaking near the middle with a barbarous, heart wrenching massacre that results in irreversible divisions, the plot digresses into a long winded, meandering, melodramatic and ultimately trite tale of revenge as the focus shifts to the second leads Yan Xun and Chun'er. They are parallel selfish and amoral characters who go off the rails albeit for good reason and become consumed by hate and revenge. Although Li Qin does a fantastic job making a delusional, entitled and spoilt princess somewhat empathetic, the character Chun'er is not smart or interesting enough to command the amount of screen time she got and in so many gratuitous sub-plots. Xing'er/Chu Qiao's character is thrown under the bus in these arcs where she is dumbed down, stagnates and even regresses on several fronts when she excuses Yan Xun's misdeeds and lies at the cost of many lives. Like Chun'er she closes both eyes to the fact that Yan Xun sold her an empty dream and is nothing but a selfish, heartless prick with no game plan, is of mediocre ability and has no vision.

Yan Xun is a well written, complex and interesting antagonist. It is hinted from the beginning that he is innately selfish and quite manipulative, traits that rule him after the loss he experiences. This has to be said - this role however was badly miscast and that is why the drama pretty much implodes in the second half, from the moment Yan Xun takes centerstage. Shawn Dou is a blank actor that never compelled me because underneath the surface of his toothy, million dollar smile, there is not much to him. He can only pull off easy going, laid back two dimensional good guy roles and from his blank placid gaze it is clear he never really gets deep into character, he is the epitome of still waters run shallow. They would have been way better off sticking a Darth Vader mask over him rather than to inflict the wooden, constipated expression he wore for over half the damn drama on us. And the annoying sibilant "dark" whisper that became his voice made him the first male character I have ever been tempted to mute in a c-drama. To me, there is no believable triangle in this drama because there is zero spark between him and Zhao Liying. Put against an intensely masculine actor like Lin Gengxin, Shawn Dou's utter lack of sex appeal (男人味) is painfully obvious. I don't mean to offend his fans but this is too important a role that got way too much screen time to have been so poorly cast. I struggled to complete this drama because I lost all interest in the Yanbei arcs and the last few episodes are simply incoherent.

I was well warned that this drama has the worst open ending ever. The problem is that unlike The Rise of Phoenixes, it is not just about one bad ending episode. This drama starts to sink from about the halfway point where my intriguing historical spy / assassin drama turns into yet another boring revenge drama and my strong female allows her dreams to be subsumed by someone else's agenda. The only reason I didn't drop this is the remarkable chemistry between Yuwen Yue and Xing'er. I am reading the book (which is long but riveting) so I know their story does go on and the portrayal of both characters are quite faithful to the novel. Many much more interesting sub-plots didn't play out because they wasted 15-20 episodes on the most boring Yan Xun and Chun'er. Sadly the odds of this ever being completed with the original cast are low.

This drama could have, would have, and should have been epic but it just isn't. All it is is unfinished. Thus I rate the first few arcs 9.0/9.5 but the second half is at best a 5.5/6.0. My overall score is 7.5 which I consider generous. This is one that must be watched with adjusted expectations.
