Li Xiang saw that the landlady was playing dumb and not very cooperative, so he said, "How could you not know? How many people leave each year? Besides, they're all locals, everyone knows each other, can't you even remember these people?"
The landlady, being cornered by Li Xiang, finally named a few people who had quit, then made an excuse that she was busy and left to attend to other matters.
Mao Ji looked at the landlady's departing figure and suspiciously said to Li Xiang:
"Why do I feel that this landlady has a problem?"
Cao Gang nodded affirmatively and said, "Be more confident, remove the 'feel'."
"Should we ask the factory workers instead?"
Then, they went back to the factory, found the worker who had called the landlady for them earlier, and asked, "In recent years, has anyone gone missing from our factory, or has there been any unusual incidents?"
The worker curiously asked back, "Are you talking about the body dug up in the grave?"
