The Wú Míng Assault Corps is a penal military regiment. All its members are denied a name and instead are given a serial number. The regiment is formed from the most dangerous and violent elements of the regular Yu Jing forces, often referred to as “pigs for the slaughter”. All Wú Míng live on probation and the Zhànying Imperial Agents are their handlers. By virtue of being the lowest rank of agent, the Zhànying usually perform their own dirty work, making them no stranger to both shady deals and firefights.
