A bizarre global examination suddenly descends upon the world, throwing thirty million candidates into real examination grounds filled with zombie hordes, vengeful ghosts, mutant species, and the apocalypse. Correct answers earn points, while wrong answers mean instant death. Points can be exchanged for wealth, bloodlines, and power. To uncover the truth, the Ministry of State Security brings out Ye Lin, a death-row convict from the world's largest prison. With his astonishing powers of observation and deduction, he repeatedly solves seemingly impossible questions, only to discover that the examination grounds extend far beyond Earth. All the races of the Milky Way are candidates, and even gods are nothing more than exam questions. To escape alive, Ye Lin decides to track down the question setters and bring this examination to its knees.
