Murder at Waterside Mansion

The moment the door was kicked open, Lijia Lu would never forget that scene in his life. The girl stood in the entrance hall, her white dress splattered with blood, and the knife she held in her hand fell to the ground. She looked over with empty eyes, like a doll whose soul had been drained out. In the living room, one chair and two bodies. Only the head of one body was left, which was placed neatly on the table, with its eyes facing the other body - the headless body. There are three cups of cool tea on the table. She was the only survivor at the scene and the person closest to the two bodies. The newly recruited criminal police officer Lijia Lu encountered such a case when he appeared on the scene for the first time.

The clock rang at midnight, and the mystery of Waterside Mansion had just begun. Intention: family affection
