This is a world where the gods have long since departed, leaving only wreckage and embers. The world is filled with "divine radiation", and ordinary people will go crazy or mutate when exposed to it. Only by "imitating the gods" can we analyze the traces left by the gods and use their power to act. The world is divided into countless dangerous "forgotten places" by huge "divine corpses" and "miracles", and human beings huddle in safe areas to survive.
