"So, how did you know there was something wrong with our chicken soup?" Boss Fang also stared at the man.
Everyone's eyes focused on the man for a moment.
The man immediately felt the pressure and said, "How would I not know? I saw my little sister drink the chicken soup with my own eyes. She was fine before, but something happened after she drank it. So, it must be the soup."
Lin Fan said, "Only she drank the chicken soup among your family? Why didn't the rest of you drink it?"
The woman said, "It's like this, we are tourists, we were out playing all day, and we came here for dinner at night. After ordering, we went to the restroom while waiting for the food. When I returned from the restroom, I found my sister poisoned."
Lin Fan said, "Did your whole family go to the restroom?"
The woman said, "No, we were afraid someone would take our seats, so we deliberately left one person behind."
Lin Fan said, "Who stayed behind?"
