Shen Mo accidentally awakened the [Moral Balance] system, which can quantify the moral value of everything in the world. In this different world where demons are rampant, the powerful supernatural organization "Holy Light Society" rules everything in the name of justice, but in fact, it secretly colludes with demons to squeeze the vitality of ordinary people. When the Holy Light Society asked Shen Mo to hand over the system, he directly disclosed the negative information about the negative moral value of the other party's high-level officials, which shocked the entire network. What's even more shocking is that he discovered that he had awakened not only the system, but also the inheritance of the ancient contract master - he could contract monsters for his own use. The Holy Light will regard him as the number one threat and send out elites to hunt him down. Shen Mo backhandedly contracted an imprisoned S-class demon to complete his counterattack. From then on, a contractor who kidnapped all hypocrites morally embarked on the road to subvert the entire world.
