Zeng Wenxi stayed behind to take care of Shen Xin and Ding Yuwei.
She had stepped out earlier when Zhang Hancheng started discussing the case.
When she noticed Qian Zidan running to the nurses' station to borrow a whiteboard, she pushed the door open and came back in, asking what was going on.

Qian Zidan shoved the whiteboard into Zhao Tianxing's hands for him to hold, then said, "From your perspective, the Li Siyu case is already solved. The killer is Wang Liang, and the motive and sequence of events are all perfectly clear."
"But putting Li Siyu aside and looking at this from our National Security perspective, I believe the situation might look something like this."
