I was greatly entertained.
A great story with skilled actors/actresses.
So many times I held my breath as I wondered how the the perfectly-matched pair was going to solve their crisis.
The series has entailed some good amount of history, politics, wuxia world, intelligence network, patriotism, wars, spying, betrayal, kingship, and stress of humanity.

Things are not always what they seem .
One of the 4 fine gentleman Mr. Yu is not who you see or think he is.
His urge for peace turns out to be the false-face for the urge to rule the world.
He did it in a rather cruel way, but close to perfection eluding FenLanxi's intel network.

An unexpected ending - but it's a good ending.
Hope you've enjoyed it as much as I did.
