Delivery worker Lin Xiao accidentally awakens to the negative review system. Starting from giving negative reviews to Internet celebrity restaurants, he gradually exposes and challenges the hypocrisy and injustice of the real world. In the early days, he used bad reviews to gain abilities and solve his personal difficulties. However, he was targeted by the Zhao family of the ancient martial arts family and was involved in the overt and covert fight between the Lawful Alliance and the Reform Society. In the mid-term, Lin Xiao's target of criticism shifted from specific things to corrupt rules. He joined forces with the Reform Society and the Free City to fight against Zhao Tianhao's conspiracy and the taboo experiments of the secret cult, while pursuing a cure for his mother's rheumatism. In the later period, Lin Xiao faced the obliteration of the rules of the agents of heaven and revealed the truth of the civilization of the ancient gods. Finally, as the ultimate critic, he deconstructed the underlying logic of the world and brought a new balance to the internal and external world while avoiding the disaster of Taoism.
