There is positive space on the lake surface, reverse space under the lake surface, and random and flowing lake water under the lake surface. Occasionally, it will bring all kinds of terrifying alien creatures, wandering in the deserted city. Until one day the Blue Star evolves and the Cube arrives... Ye An, who died in the cube a year later, traveled back to a year ago, where should he go... This novel and its characters are purely fictitious.
