Han Jingyi was a wealthy woman worth tens of millions. When her heart condition flared up, she didn’t die in her own villa, but on the operating table. Six people on the surgical team, led by Liu Xianfeng, director of Liancheng No. 8 Hospital, were directly involved in her heart bypass operation. Before surgery, Han Jingyi placed a curse on the doctors preparing to operate on her, warning that if anything happened to her during the procedure, she would curse their souls to hell and her ghost would never let them go. After the curse, the three surgeons who took part in the operation died one after another. Each death was connected to a mysterious fax. Before long, the hospital was filled with the atmosphere of a funeral home. A voice just like Han Jingyi’s wandered through the cardiology ward, day after day hunting down those who had killed her. The local police station formally took over the case. As the story unfolded in a series of terrifying twists, they eventually discovered that the voice belonged to Huang Xiangyun, an ordinary nurse in the cardiac surgery department of Liancheng No. 8 Hospital. Thus began a shocking series of murders...
That's quite interesting.
It's so good! I've watched it repeatedly.
