Shanhe Backup

After the Daytime Catastrophe, humans lived underground for forty-seven years. The job of historical verifier Lu Chenzhou is to prove that old photos, old newspapers and old radios are all fake. Until one day, he heard the surface weather from a radio without power: Beijing will be fine tomorrow, and the Ninth Mountain River Reservoir will be permanently closed in forty-eight hours. The announcer then called him brother, but the household registration records showed that he never had a sister.
