A huge comet fragment that deviates from the predicted orbit hits the moon, triggering a chain of disasters that far exceeds all mathematical models. Not instantaneous destruction, but a slow, suffocating end. The change in the moon's orbit caused the earth's axis to deflect, the earth's rotation gradually slowed down, and the days and nights began to lengthen abnormally. What follows is global geomagnetic disorder, climate madness and gravity distortion. The former order disintegrated amidst the stretching of time and frequent disasters. Lin Jian narrowly survived the initial global blackout, relying on professional knowledge and over-prepared hoarding to retreat to her high-rise apartment before the city plunged into complete darkness and chaos. His goal is simple, to survive, amidst the noise of his mother's old radio, waiting for a dawn that may never come. But he soon discovered that the most terrifying thing in the long dark night may not be the cold, hunger or crazy geological activities, but the alienated human heart that is also groping in the dark, fighting for a glimmer of life.
