King Yang Qiu had two types of personal guards.
The first type were his personal security guards. They were basically warriors whose heads were filled with muscle, or Oracles whose brains had been replaced by the power of the Ghost God. They had no other skills except killing, torching, or serving as human shields when necessary.
The second type were the talented people whom he had worked very hard to recruit. These were the people who possessed all sorts of amazing talents, such as those who managed his tax revenues, trained his hunting dogs and falcons, trained his subordinates and security guards, and men like Wu Qi, who advised him on government and military affairs.
