Qin Ya ignored Tian Fan's question, observing the situation on the rooftop while closing the door. He then headed towards the parapet and asked, "This afternoon, when the music started playing, did you see those people on the opposite building?"
Yu Nuo had already climbed up from the ground, her feet unsteady as she walked to Qin Ya's side. Hearing his question, she quickly said, "I did see them; a man in his twenties and two women, probably around the same age. Did they commit a crime, Officer?"
"They couldn't have. They were just trying to attract zombies using sound, right? That's not illegal, is it?" Tian Fan asked, somewhat incredulous.
"So, there were three people…"
Qin Ya shook his head, denying Tian Fan and Yu Nuo's speculations. His gaze swept across the dark windows of Building No. 3, hoping to find some clues. Unfortunately, he was disappointed; there was no sign of light, as if the entire building had turned into a ghostly tower.
