It was already completely dark. The rooftop of the high-rise building was exposed, and the cold wind cut through the air as if it were a knife scraping across the skin.
Tang Qingzhong took off his suit jacket and offered it to Gu Nuan, "Wear this."
Gu Nuan shook her head; she had an extra women's suit jacket with her that could also block the wind.
Seeing her lips turn white from the wind, Tang Qingzhong regretfully clutched his head and said, "I should have listened to you—"
Whether someone intentionally locked the rooftop door or not, had they chosen not to linger here at the beginning and instead gone downstairs, they wouldn't be trapped now.
"Senior, don't blame yourself." Gu Nuan consoled him, "Let's keep looking up here."
"Looking for what?" Tang Qingzhong only remembered that he had already searched the rooftop once for evidence and just as she had said, found nothing.
