Dome Restricted Area

A hundred years later, the world is covered by a dome. A person's life is determined by the system score. The S-class takes control of the city, and the E-class is recycled. On the day of the adult test at the age of eighteen, Lin Xu discovered that he was not among the "human model" of the system. When ratings fail, order begins to collapse. What he wants to figure out is---- Is the dome protecting humans or screening humans?
