Brother Yu died without any suspense. In the days that followed, Brother Song didn't use his communicator to contact others; he only contacted a friend from the municipal government once using his work communicator. He found out that the communicator used by the whistleblower was a stolen one from two years ago and had a fake identity covering the original owner's information. It had been used intermittently over these two years, proving the whistleblower was from Flower City.
Additionally, the whistleblower using this communicator had reported more than just Brother Yu. They subsequently reported three other players involved in kidnapping and human trafficking—the shared trait of these people being they frequently mingled with unsuccessful groups of players and engaged in shady business.
