There Is a Door Under the Soil

My name is Chen Shoushan, and I do the work of drilling holes, exploring wells, and finding missing people for others. When I was sixteen, my father entered an ancient tomb with no owner and never came back. Before he disappeared, he only left me one sentence: "The tomb is for the dead, and the door is open for the living. If you hear someone knocking on the door in the future, don't answer it." Twelve years later, a landslide occurred at a construction site in Linjiang City, and workers dug out a sealed brick room seventeen meters underground. There was no coffin or bones in the brick chamber, just a black door embedded in the ground. Twelve names are engraved on the door. Eleven of them were workers who entered the brick room that day. The last one is me. That night, there were three knocks under the door. And my father, who had been missing for twelve years, called my name from behind the door.
