Test Subject

In a universe ruled by gods, the Grim Reaper Satan experiments on humans to discover whether their souls enter the void after death. He wants to know what his test subjects can teach him, but they learn to resist his experiments and lead their fellow subjects in a struggle for freedom and survival. Yet other civilizations exist: Can the angelic civilization stop Satan? Can the demonic civilization spread across Aimei Star? Can the test subjects create a new world and change the existing one, where humans are experimented on for the sake of the Grim Reaper? Can humanity coexist with other races in this vast universe?
