บท 519: Chapter 519 Decryption 1:

"Xiaocang, the matter you asked us to investigate is very strange. There are no clues at all. The cameras were indeed broken that day, and there were no eyewitnesses.

The person on the other end of the phone said with difficulty.

"So you haven't found a single clue?" Xiao Qingcang furrowed his brows and asked. The friend who had called him was a police officer from Yucheng City. If he said there was nothing that could be done, then there really were no clues to be found!
