As they approached Gu Nuan's room, Tang Shaohong became more cautious and pulled Old Lu to hide at the corner to observe.
The corridor was silent, and it seemed there was not a single person.
Old Lu asked him, "Why—"
Before he could finish, Tang Shaohong covered his mouth with his hand.
Then, both of them stared in surprise as the room's door appeared to be effortlessly blown open by a gust of wind. After waiting for a long time, it seemed no one was inside the room, so no one came out to close the door.
Frightened, Old Lu jumped onto Tang Shaohong, "Look, has someone disappeared again?"
Tang Shaohong quickly dug into his pocket for his phone while leading Old Lu toward the service elevator that Old Lu mentioned was used by the cleaning staff.
When he took out his phone, he realized there was indeed no signal.
Fortunately, Gu Nuan had already told him where to meet up before.
