I was excited for this to air as I really enjoyed watching Lin Yu Shen in his many supportive roles in varies historical dramas. The first episode took off with a promising start. But overall story was average with mediocre dialogue at best. Nothing witty or memorable.

Costumes: some of the best I've seen. I always appreciate the fine details of these elaborate costumes. The FL had almost daily outfits.
Fight scenes: great choreography and no shortage of them.

I wish the casting matched to the characters age.

You have the drama start off with ML at the age of 13. He's smart can save bunch of people with his quick thinking then he leaves. BOOM! 5 years later he should be (18 or at least under 20) but looking like a 35-40 year old. All his youthful smarts disappeared, and he got himself almost killed many times over. Doesn't make a whole lot of sense.
Good thing FL came to the rescue! Now the FL has a lot of historical dramas under her belt, but there was 0 chemistry between her and this ML.
Mid way through FL left and came in FL2 the poison girl. Again, this character rescued ML a million time because she's smarter than him. Somewhere along the way ML's Kungfu improved 10x and in a flash ended with an anti-climatic finish. What I call an EASY way out with so many stereotypical C-dramas.
