Su Qingnuan paused, slightly startled, and stopped in her tracks, tilting her head to look.
The white, spotless wall showed no trace of dirt.
Su Qingnuan frowned and pressed her ear against the wall.
"How should I do this? I've been doing exactly what you told me…."
Although the voice was faint and unclear, Su Qingnuan could mostly discern what was going on behind the wall.
Her frown deepened as she walked to the door and knocked.
The door opened from the outside.
A man dressed in a black security uniform stood at the door, his face devoid of emotion as he looked at her.
"Do you need something?" he asked.
Su Qingnuan pointed at the neighboring room. "I heard someone talking next door. Could you go check it out?"
The man nodded. "Understood. Anything else?"
"That's all."
The door closed again.
Su Qingnuan sat down on the chair, her gaze fixated on the wall to her right.
After a long while, she stood up and leaned against the wall.
The voices continued.
