Everyone in this world must establish certain relationships with the people around them, such as relatives, friends, teachers and students, lovers, and so on. Whenever you fall into a so-called relationship, there must be ethical and moral constraints, just like parents have the obligation to raise children, and when children become adults, they must also perform filial piety to support their elderly parents, and a married woman must not have an affair with others. However, the story takes place in a completely opposite world. In this world, people are also trapped in various relationships, but they are not bound by morality. There is no law, no system, no police station, and no supervision. No one forces you to marry someone you don't like, no one forces you to do the so-called Kong Rong's resignation, no one insists on your care and love, no one investigates your half-heartedness, and there are no regulations. But freedom is also relative. If you commit a crime and do not punish it, you will be helping the evildoer and giving wings to the tiger. If there is chaos and no measures are taken, black and white will be confused and social order will be disrupted. The growth of evil will also lead to the emergence of justice. Therefore, such a special social environment has given rise to two professions: "Prosecutor" and "Sanction Officer". The former judges whether an incident is a crime without moral constraints, and the latter takes sanctions against criminals. Of course, prosecutors also have a set of standards for judging incidents. It is roughly as follows: there are casualties in the incident, conflicts between two or more parties arise in the incident, financial interests are involved in the incident, unfair means are used to complete something, and there are elements of evil forces in the incident. If any of the above items are violated, it can be considered a crime without moral restraint.
