Migratory Birds and the Smell of Blood

The smell of the blood of the "waiting girl" can attract migratory birds. My mother was willing to be controlled by the "waiting girl" in order to pay off her debt. In order to avenge his sister, Chen Yu dragged me to escape in the wind and snow. The smell of blood weaves a web and the migratory birds chase their lives. Can we tear apart this blood-based scam?
