Underworld workplace;
Although the Mirror of Evil can change good and evil, it cannot help the little ghosts who come and go bribe the law enforcers. Therefore, Emperor Fengdu arranged for the five ghost emperors to go to the Yang Realm to select the middle law enforcement. When there are errors in the law enforcement and there are objections, the middle law enforcement officers will go to the Yang Realm to verify the true and false, good and evil, and then the four judges will make corresponding rewards and punishments.
