The Four Collection

A government department known as the Six Panels appoints their best officer to infiltrate a special force called the Divine Constabulary, to ensure their way in stopping the circulation of counterfeit coin currency in the capital.

Four detectives (Emotionless, Iron Hands, Life Snatcher, and Coldblood), each uniquely skilled with their own individual superpowers, are sent to investigate a murder outside the city. During the investigation, they unexpectedly stumble across clues to an unsolved murder from 12 years previous that hits close to home for one of them. Suddenly, the investigation becomes all too personal, and the detectives must put their lives on the line to solve this crime!

Emotionless has left Six Doors, as has Cold Blood, who has decided to investigate the death of Lord Bu on his own. The departure of two of the four constables has effectively left Six Doors defunct. At this time, trouble begins to brew in the Imperial Palace as Emperor Huizong plans to travel incognito to the outside world. When he is almost assassinated and subsequently disappears, Cold Blood, Emotionless, Iron Hands and Life Snatcher must band together once again under Master Zhuge to save the empire from a massive conspiracy.
