0:17, Please Confirm Your Name

In Qiheng City, people will not disappear out of thin air - the city will first delete his name and then make everyone believe that he never existed. At 0:17 midnight, a fire alarm suddenly came out from a residential building with only 16 floors in Qiheng City: "Someone is trapped on the 17th floor." Fire protection facilities inspection engineer Zhou Jiming checked the as-built drawings, stair heights, elevator procedures and building facades, and all evidence proved that the seventeenth floor did not exist. But when he walked into the safety staircase, there was really an extra layer above the sixteenth floor. What's even weirder is that after he rescued a middle-aged woman from that floor, there was no trace of her existence in the property files, identity records, neighbor memories, or even her biological son's cell phone. The next day, the map of the city was missing one stop, and the last train had one more passenger. Zhou Jiming gradually discovered that twenty-three years ago, an underground accident that no one remembered happened in Qiheng City. There are seventeen lines in the accident list, but there are only sixteen names. The blank seventeenth line is waiting for the whole city to fill it with a person.
