Cold Blood chances upon the scent of blood while Department Six and the Divine Constabulary are setting up camp in a foggy forest. Running ahead of the others, Cold Blood, Life Snatcher, Iron hands and Ji Yaohua arrive in front of a locked and seemingly abandoned house. In attempt to break the lock, Cold Blood is attacked by a cannon and barely escapes. He notices the person behind the cannon - Zhuge Zhengwo. Keeping the information to himself, the rest of Department Six and the Divine Constabulary rush into the house to discover the bloodshed of many and there is only one survivor, a man Zhuge Zhengwo identifies as Ouyang Da, someone whose face had disappeared off the pugilist world twelve years ago. Every one else have died of similar wounds, all caused by the same weapon that Cold Blood was attacked with. Zhuge Zhengwo shows keen interest in the incident and promptly asks Sheriff King to turn over the case to the Divine Constabulary. Sheriff King agrees, and Ji Yaohua along with the others in Department Six protest; there have been similar cases of massacres that they have been investigating, each with a death of a man that was supposed to have died twelve years ago. The deaths are all tied to Zhuge Zhengwo, as these men were part of the Gang of Twelve supposedly executed by him when they massacred Sheng Yayu's, now Heartless, family. Department Six strongly believe it is likely that Zhuge Zhengwo had lied about executing the Gang of Twelve and rose to fame, only to silence those that were supposed to have been dead for twelve years now so that his secret would not be found out. Sheriff King believes in his friend but instructs Department Six to continue investigate quietly.
