This is an attic, with a simple bed inside that looks like it should belong to a worker's room. Lin Chuan opened the door to the room, and the corridor was still lit with a dim light. The carpet laid on the corridor made things convenient for Lin Chuan, as the carpet had a soundproofing effect; so when Lin Chuan walked on it, there was hardly any noise at all.
All rooms on the third floor should be the rooms for workers and maids, so Lin Chuan decided to head towards the second floor.
There were five rooms on the second floor, each tightly closed, which made it difficult for Lin Chuan to judge. However, Lin Chuan made a quick assessment. According to the way Chinese officials think, "fortune comes from the East," so the room on the eastern side must undoubtedly be the master's room.
