Qin Mu made use of his "devil" physique, which made him "unable to be selected" (difficult to hold him responsible under social rules) due to his "advanced age" and "terminal illness", and combined with the abilities granted by the system such as "disease control at will", to transform into an "eighty-year emperor" and a "subway judge", specializing in punishing and "confronting" those unhealthy phenomena in society. The logic of his behavior is to use his own characteristics of being carefree, terminally ill, and not afraid of trouble and death threats to use tough methods such as "magic confrontation" and "ultimate counterattack" to stand up for the good people in society.
