Originating from the inner curiosity about the unknown and the desire for abilities, the human body will produce a substance that promotes supernatural abilities. This substance is called Ua. Individuals with supernatural abilities have extraordinary physical fitness and need to eat raw meat, and are classified as aliens. Organizations represented by Project Zero study this phenomenon and classify alien races into four levels: SS, S, A, and B based on differences in individuals and ability to control alien abilities. Zhang Zheng, the director of Project Zero, formed a force called the Navigators, hired technical consultant Devo to analyze the structural differences between aliens and humans, capture aliens, and secretly conduct a large number of individual experiments. An ordinary sophomore, Xia Weifeng, accidentally fell into traps and was forced to get involved in one inter-racial fight after another.
