Bab 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. We wanted to investigate the doctors and nurses at the time, but some have gone abroad, some have passed away, and some we just can't find. It's very difficult!" 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!

"Yes, this case was handled very cleanly!" the police hinted at something more.

"Especially clean?" Xiao Qingcang repeated the phrase. "That would suggest that this person is either an experienced criminal or has significant backing, able to destroy all evidence and even prevent the police from investigating?"
