Qi Jingyun gathered the personnel on duty for the three days before and after the incident.
Yang Ruxin questioned them one by one about their situation while on duty. Nothing seemed amiss, and finally, it was the turn of the four prison guards on duty in the cell that day.
"Are you the Old Liu who delivers meals to the prisoners?" Yang Ruxin first asked a middle-aged man dressed in a prison guard uniform.
"Yes, madam." The prison guard replied respectfully, kneeling on the ground.
"Stand up and talk." Yang Ruxin nodded, "Tell me about what happened on the day of the incident, in detail."
The prison guard nodded and seriously recounted the events of that day.
"Wait." Yang Ruxin suddenly raised her hand, "Did you say there was someone inside before?"
