The mastermind is dead

"The owner of the house is related to Qiang Hu, and Qiang Hu himself is a somewhat introverted person. He used to be a student at a university in Serene City, but he was later expelled for causing a small-scale explosion in the laboratory. His grandfather was the old butler of the Hong family, so he and Hong Wen grew up together. After Qiang Hu was expelled from school, the Hong family found him a job on account of their past friendship..."

The police first explained Qiang Hu's situation in detail.

According to them, Qiang Hu had vented his anger on Hong Wen after learning of her death and had specially returned to Huaning County to take revenge.

The original residents of his temporary residence did not move, but their entire family was killed.
