Xie Yunfan, an ordinary junior student, is actually the hidden game master ranked number one in the entire server. One day, he accidentally activated the "Humanity Experiment System" and was pulled into a strange assessment space. Here, everyone who enters the "Hell Campus" must face the test of the seven deadly sins-arrogance, jealousy, rage, laziness, greed, gluttony, and lust. Some people degenerate into monsters due to jealousy of their friends, some lose their minds due to greed and become puppets, and many more collapse under endless mental torture. Relying on the thinking ability and psychological quality of a top game master, Xie Yunfan not only passed every test perfectly, but also gained power that did not belong to this dimension. However, he soon discovered that there was a bigger secret hidden behind this system: his classmates were actually real humans, and the "Hell Campus" was devouring the real world. When the seventh test comes, Xie Yunfan must make a choice - continue to watch this human experiment with a cold eye, or use his own ability to save everyone?
