Vientiane Maintenance Department

"Master, the sun in my house is broken." At 00:07, a red landline phone that had been disconnected suddenly rang. Municipal maintenance worker Chen Xu followed the phone call and drove into Ningheli, which does not exist on the map. There, the sun sets every seven minutes; every time it sets, one person disappears from reality and everyone's memory. When Chen Xu arrived, the seventh sunset had already begun. From that day on, all the faults that should not exist have found him: the ceiling is leaking starlight downstairs, the refrigerator is freezing last July, a subway has lost "tomorrow" and is carrying a full bus of passengers towards yesterday; and a man who has been dead for ten years still comes home from get off work on time every day... Others rely on guns to deal with abnormalities, but Chen Xu relies on multimeters, wrenches, insulating tape, and the simplest rules of maintenance workers: Cut off risks first, then find a way back; confirm who the customer is first, and then decide what counts as repair. Until a work order from thirty-seven years later appeared------ Fault object: this universe. Fault content: Continuously generate the future. Chen Xu answered the red phone that kept ringing: "Vientiane Maintenance Department, please speak."
