Li Jia came to school in Hong Kong alone. In the car, he recalled that his mother had schizophrenia and died at the age of 24. His brother also suffered from schizophrenia at the age of 24 and he was almost 24 years old. Sitting on the bus, a girl riding a skateboard almost collided with the bus. Li Jia kept watching the girl riding a skateboard passing by a woman burning paper on the side of the road, and a piece of paper flew onto the glass of Li Jia’s seat. .

After getting off the bus, Li Jia went to the Reporting Office of the Chinese University of Hong Kong’s Master of Psychology to sign in. A man who claimed to be Wang Qianran ran out to make a report. This is a man wearing a skirt and a wig. The person at the sign-in area asked him to leave quickly. At this time, the man heard the sound of the skateboard girl clawing the bell on the backpack and was stimulated to pull the fork. He asked her why she abandoned herself with a knife holder on the neck of the fork. ? Zhang Chacha didn’t know this man at all and was frightened by being held hostage by a knife. The person next to him said that Wang Qianran had passed away for a year. This man was her boyfriend and was crazy. Li Jia found out that the bell was attracting the man and took the bell to attract the man’s attention, and finally caught the man with the help of the security guard.

Shicheng, a medical student on the side, saw Li Jia saving a person and took the initiative to greet him, but Li Jia hurried away because he had to go to the classroom. When he came to the classroom, a person who claimed to be a mentor was speaking on stage. No one noticed his abnormality until he asked Li Jia a question. Li Jia found something wrong and asked who he was? At this time, the real mentor Chen Mingxuan came out and said that this was a test, and Li Jia didn’t know that the reason why Chen Mingxuan was willing to accept him was because he wanted to experiment with him as a patient.

After coming out of the classroom, Li Jia was not assigned to the dormitory because he missed the time. Zhang Chacha saw Li Jia and offered to introduce him to a very cheap house. Zhang Chacha took Li Jia to the place where he lived. There were many cats in this place and it was very gloomy. The residents living on the fifth floor were also very strange. Li Jia passed by the door of each household and carefully analyzed what kind of people the households living here are. But Li Jia said that there are no ghosts in the world and he is not afraid. Li Jia discovered that Zhang Chacha was not the landlord and asked why the house is so cheap? Zhang Chacha said that he was a real estate agency and asked Li Jia not to go out, and then left by himself.

Li Jia was washing in the toilet when he heard a sound outside, he came out to check and saw that it was a black cat eating outside the window. At this time, Li Jia’s family called and Li Jia took the call and looked again and found that the black cat was gone. Back in the room, Li Jia found a red ball and heard a knock on the door, and came out to see the figure of a woman. When Li Jia stepped forward to check, a horrified face turned around, and Li Jia suddenly woke up, and it was a dream. After Li Jia woke up, he rushed to the school to find Professor Chen Mingxuan and asked about the possibility of schizophrenia and heredity.

Professor Chen Mingxuan believed that he should not draw conclusions about what has not happened and then left Li Jia’s contact information. Professor Chen Mingxuan is still studying a person named Bertha, and Li Jia is also an observation object. Shicheng found Li Jia and wanted to take him to find a house, but when he heard that Li Jia had found the house, he wanted to take a look. After arriving at the place, Shicheng was frightened and told Li Jia that the place he lived in was not clean, and then left in fright. Li Jia went home and found that the elevator was broken and he could only take the stairs. At the corner of the stairs, he picked up the ball in his home. He felt that someone had thrown it down, so he looked upstairs and saw a man.
