A global strong earthquake suddenly tore apart the earth's surface, sending tens of millions of tons of rock and soil rushing downwards along with mud. Half of the city was reduced to a burial ground within a few hours. Construction engineer Lu Chen crawled out of the collapsed office building and met Su Wan, a doctor holding a first aid kit. When the roar of the aftershocks intertwined with the cries of the survivors, they discovered that the real desperate situation was not the ruins without water and food, but the glimmer of humanity that maintained in the darkness - the rusty fire ax split the concrete, the threads to suture the wounds were taken from the curtains, and the body temperature of strangers became the only heating device. When the last radio transmitted intermittent rescue signals, this group of people who were piecing together hope among the rubble finally understood: as long as people are still supporting each other, the buried city will never truly die.
