Epic, Mind blowing & simply amazing story with full of twists & turns, no matter how smart the police is, the criminals are equally smart.

Zhang Yi as ML always delivers, a smart veteran police officer with calm mindset & very good memory always remembers even the smallest details of the cases, always on the front & leads like a leader, everything seems to revolve around him because of his capabilities as a capable police officer.

Other Support Characters are not simply there for the script, they have smart brains as well & deal with issues with maturity.

I specially liked the character of Gu Kaiyan, a smart capable & calm female police officer that deals with cases with calmness & looks for loopholes in the statements of the criminals, she really reads the criminals like a book & knows which page contains how many mistakes.

Romance was good, for mature audience, no kisses or anything though but we can see the emotions being conveyed.

Ending was expected, everyone got what they deserved but someone's missing, I won't spoil though, you guys can understand after watching.
