Natsume is a lonely boy who has been able to see monsters since he was a child, but was rejected because of it. By chance, he was pulled into the chat group "Wanjie Ghost Mutual Aid Society" by a mysterious mobile phone APP. There are forgotten mountain gods, lost river uncles, aggrieved urban legends, and even monsters from other worlds in the group. They are not here to scare people, but to issue tasks and seek help from humans! After completing the mission, Natsume will be able to obtain heaven-defying rewards such as "God-level Spirit Control Technique", "Yin Yang Pupil", and "Ghost King Contract". In order to no longer be troubled by monsters and to become stronger, Natsume bit the bullet and accepted various "weird" commissions from the group. He discovered that there were unknown stories behind the "evil spirits" that were misunderstood by the world. When he solved one supernatural incident after another, subdued one powerful monster after another, and gradually became the "big boss" of the group, he was shocked to realize that he had accidentally stood at the pinnacle of the Yin and Yang worlds and became the new "Master of the Yins of the Ten Thousand Realms"! "Wait a minute, I just want to be friends with the monsters quietly!" Natsume said innocently.
