Story line is good up until the ending. The story takes you to solving mysteries like a Sherlock Holmes and his sidekick.

The choreography of the fight scenes is fantastic.

Be prepared for disappointment though.
Character development is good.
But the endings in these dramas are too often disappointing as is with this one.

Li Lianhua is an amazing character but has a character flaw where others care about his life more than he does.

I feel robbed of 40 hours watching 40 episodes to have this nebulous ending where they built up thos story line beautifully.

The writer should be shot for writing this.
