One thing doesn't make sense....*SPOILER*
How did Zhaoyang expect to collect any money when he killed his partner at the end? Jinming was pretending to be the boy's uncle, so he was the only one that could have collected on the boy's death, and vice versa. Zhaoyang couldn't have collected any money from either of their deaths because he wasn't a relative. Was he just being irrational?
Please correct me if that isn't how the system works.
