When Zhang Qiang and Chen An left the house together the next morning, it just so happened that Old Wang wouldn't be able to come in for his shift until noon. Although what Chen An had said to Zhang Qiang the day before made a lot of sense, once Zhang Qiang had calmed down, he still felt that something wasn't quite right.
But relying on Zhang Qiang's brain to figure it out proved fruitless; the not-so-bright Zhang Qiang still had no clue and simply did not bother thinking about it further.
Chen An wasn't sure if Zhang Qiang would notice anything, but judging from the time he had spent with Zhang Qiang, it was highly likely that Zhang Qiang wouldn't understand the situation. Instead of always being careful not to be discovered by Zhang Qiang, it was wiser to be wary of the shrewd Old Wang in the maintenance room.
