When the video began playing, everyone saw Li Zhuojia arrive at the Qin Residence. Li Zhuojia handed the box of medicine to the Qin Residence's family doctor.
Then, Li Zhuojia left.
After that, the doctor opened the box of medicine and gave it to Qin Hongzhi to take.
The whole process was done under surveillance. As a result, the doctor did not have any time to switch the medicine to something else.
Five minutes after Qin Hongzhi took the medicine, his body suddenly developed violent convulsions. Then, fifteen minutes later, Qin Hongzhi's heart stopped.
The entire video proved that Qin Hongzhi indeed took Jian Yiling's medicine before he died. Furthermore, throughout the entire process, there was no possibility of the medicine being switched.
Once everyone finished watching, they turned to look at Jian Yiling.
Their eyes were filled with disbelief.
"I didn't expect her to be the murderer!"
