The night was like water, the autumn breeze slightly cool.
Ling Chen stood at the top of the rooftop, his eyes sweeping around, but besides himself, there was no one else; the kidnapper had not shown up. Holding his phone, he patiently began to wait nearby.
Soon after, his phone finally rang.
"Put the money on the rooftop, and you can leave."
Without hesitation, Ling Chen tossed the trash bag to the rooftop's top and promptly returned to his car. Those wads of cash were implanted with micro-tracking devices; as soon as the kidnapper touched the money, they could track the kidnapper's whereabouts.
Several minutes passed.
"Officer Xia, any movement yet?"
"Nothing."
Odd! Ling Chen furrowed his brow as he watched the stairwell entrance of the residential building. It had been so long, yet the kidnapper hadn't come for the money.
Just as he was pondering, Xia Mutong's anxious voice suddenly came through the earpiece: "Ling Chen, the signal is gone."
"What?"
