After opening the door with a brass key, Shang Jianyao used the light from the street lamps on the ceiling to see the familiar wooden bed, sink, burgeoning screws, a red-painted wooden table, and a matching high-back chair.
It was identical to when he left.
Thanks to the underground building's excellent ventilation system and unique geographical environment, Shang Jianyao didn't even find the room depressing, nor did he see any obvious accumulation of dust.
He slowly walked in and closed the door behind him. He removed the old rag hanging by the sink, turned on the tap, and wet it.
Shang Jianyao then bent down, occasionally squatting down to wipe all the spots he could.
When he was done, it was exactly 7 p.m. Shang Jianyao—who had already showered and changed into his regular clothes at the Security Department—immediately took his key and headed for this floor's Rec Center.
