After the incident earlier, Xiao Yifei felt it was time to show them a thing or two. After settling the patient and the patient's family, Xiao Yifei went to the director's office and checked yesterday's surveillance footage with the director's permission.
It was determined that this medical accident was caused by Zheng Peng. Zheng Peng was the only one on duty in the pharmacy yesterday, and the quantity of various medicines was clearly recorded on the computer.
Zheng Peng initially refused to admit it, but when Xiao Yifei presented conclusive evidence, he suddenly began to plead, saying, "Doctor Xiao, it's true that I placed the medicines, but it was Director Sun who asked me to do it, really. He wanted to see the prescriptions you wrote, and he threatened me, saying if I didn't do as he said, my job wouldn't be secure."
