It was just that handling these matters openly was difficult and hard to explain. As a result, during this period, Jing Shu still needed to devise a way to have her father and grandfather set up some traps around the villa.
The best would be live traps: the kind that normally remain closed and are opened only when needed. She would need to consult her grandfather, who was a carpenter, and Baozi's father. They would likely understand what she meant.
Although historically, those who possessed spatial abilities might never have used such a primitive method, Jing Shu still felt a deep sense of satisfaction.
Being a person should be simple, and killing people should also be simple. Don't complicate things with unnecessary flair. If there's a direct way to smash someone to death, there's no need to consider other methods.
