There was a sudden change in the world. Jiang Mo, a student taking the postgraduate entrance examination, suffered a plane crash on his way to the examination room and was stranded on a strange desert island shrouded in "evil powers". Time here is messed up and monsters are rampant. Only by solving the puzzle of the island can you return to reality and take the fateful exam. On the surface, Jiang Mo appears to be a docile top student preparing for exams, but in his heart, he has an extremely yandere soul. He awakened the golden finger's "absolute analysis" and could see through the weaknesses of all things, but he also regarded all existences that hindered him from "going ashore" as lesions that must be eliminated. On this island, the villain is not a specific person, but the evil power itself that can corrode the mind and bend the rules. For the "perfect score" in his heart, Jiang Mo used scalpel-like calmness and madness to turn desert island survival into a bloody problem-solving process. In a strong suspense atmosphere, every breath is a countdown, and every survivor may be a disguised test question.
