In a world where memories are cleared every twenty-four hours, Lin Mo, as the "Rememberer", is the god who holds history and truth. However, when his own temple of memory began to collapse, the god fell to earth. In order to find a cure, he had to step into the "Heart of Destruction", the source of doom forgotten by the world. The only person traveling with him was a girl from the wasteland who had a map carved on her skin.
In this journey of survival, he not only has to fight against his disintegrated self, but also evades the pursuit of his old mentor. When the ultimate truth of the world - about the power of forgetting and remembering - unfolded in front of him, he discovered that the most terrifying thing was not losing memory, but remembering everything that should not be remembered. How will he choose? Will the world sleep in a false sense of stability, or wake up to a painful truth?
