The local police stations paid close attention to the deaths allegedly caused by Green Fresh. The police stations and agencies were involved in the investigation.

However, the murderer was too cunning or too skilled. They searched and searched, and all the evidence pointed to Green Fresh. The result showed that their food was poisonous. 

However, everyone knew that this was simply impossible.

Because anyone who had eaten this food knew that the food at Green Fresh was good for the body.

Also, what puzzled them the most was that the dead victims were all poor people. Their families were generally of two types. One was that their children were especially filial. The other was that their children were especially unfilial.

It was difficult to reason with either of them. They wanted compensation in terms of life or money. Those who chose money wanted a lot of it.
