Jade Cheng as the female lead, I'll give it a try..... but honestly this drama is disappointing..... To me the story is kinda awkward and boring.

Female lead is a 鏢師. Which is basically a person that helps guard/watch/deliver goods and people to a destination.... but the fact is that she doesn't have good kung fu doesnt make any sense. The male lead has better kung fu than her.... like how are you suppose to protect people's property. Also the female lead was suppose to be a maid to the Bai family to repay a favor( because the Bai's wife helped the female lead's when she was in need. The female lead is to protect the Bai's daughter and get her to successfully marry the Yang family second son.

The male lead is the Yang family second son. His parents died trying to establish a new road of trade. He wants to continue that and open a new road for the trades to go through This is what the drama is about and on their way they try to find people to support them but a lot of people dont want the new road and try to kill them on the way....

The romance between the leads is pretty cute.The male lead falls in love with the female lead from the early episodes, but the female leas is hesitant because the male lead is the suppose fiancee of the Bai's daughter. But the leads go through near death and slowly fall in love with each other. They have a decent chemistry. They have a lot more kissing scenes after episode 15.
