Lin Xi, an intern doctor, has been frail and sick since she was a child. Her parents took her to major hospitals in Beijing and Shanghai to no avail. In desperation, the parents who believed in scientific materialism followed the advice of their grandmother and obtained a piece of blood jade from the Shoulongshan Ancient Taoist Temple. It turned out that Lin Xi was born in the lunar calendar at the midnight hour and had a special constitution that was prone to evil spirits. After wearing the blood jade, the number of illnesses decreased and the feeling of spying disappeared. However, while working the night shift at the provincial hospital, Lin Xi, who was sending a sudden death patient to the morgue, encountered a strange incident. At the critical moment, can the blood jade protect her again?
