Extradition Without Name

At 11 o'clock in the evening, the power in Chongwen Building was cut off on time, but I didn't have time to walk out. In silence, the four walls turned into white - fresh mortar, airtight, no doors, no windows. The fluorescent tubes were pale and trembling, casting skewed shadows amid their buzzing sound. I came to a secret room, no, this was a classroom. Thirty old desks stood silently, but there were only ten people, ten students. No, no, there is another person here, and the eleventh person is him! How could it be him! The candlelight on the podium illuminated a yellowed roster. He stood in the light while writing, his face blurred but his voice clear: "Class. Roll call."
