After Song Qingxiao heard from Zhu Xiaoke during breakfast that the keys to the gun were with Liu Yixun, she began to pay attention to Liu Yixun's office while he was on duty.
When Nurse Zhang was busy preparing the medication for the patients, and all the other nurses were engaged, she stood by the nurses' station, which faced the office door of Liu Yixun directly. The ward was not peaceful because the patients on the third floor were rowdy.
The door was half-open, and the curtains over the glass wall had been drawn. The room looked dimly lit from Nurse Zhang's position, and she could barely see if anyone was inside.

Someone began to sing loudly, and the melody rose and fell. Nurse Zhang became distracted and turned to catch a look. Several people had gathered around the door leading into patient room number nineteen.
