It was confirmed that the nurse was not a real nurse from the hospital, but an impersonator who had intruded into the hospital. It was her poisonous injection that had caused Jia Qing's death.
The nurse was taken to the scene by the police. She explained the whole process of how she was bribed and how she committed the murder in front of the crowd. The behind-the-scenes perpetrator was indeed He Liang.
Guan Hao concluded, "Now there's a lot of evidence to prove that Jia Qing's death was caused by He Liang, not Jing Xi. As for why He Liang wanted to murder Jia Qing, we will let the police take over and investigate this issue. Now, does anyone have any questions?"
