"No, all CCTV's had been deactivated an hour before the person arrived at their house. It was deduced that he arrived around midnight." He answered, eyes glued at his computer screen. "However, I found a strange car a few blocks away from Xuan Hui's place. All black to plates. I tried to follow it but it disappeared around Kowloon. Whoever did it was a professional."

"Hmmm. I already checked all the hospitals but no one came. But we already expected this. The thing is, we don't know what the man looks like. Based on the recorded call, they can speak Cantonese fluently. It might be a native or someone who can speak multiple languages," said Qin Yuanfeng. Eyeing Lily, he continued, "Jingren said it might be someone that you offended in the past?"
