"What mystery?" Xu Tian asked.

"When I was investigating that university, I found a fenced vegetable patch in the northwest corner of the campus, I started investigating that university in early September, when the vegetable patch was still green, and by mid-September, the vegetable patch began to turn yellow, and it was the school cafeteria manager who planted the vegetable patch, and when they cleaned up the yellow stumps in the vegetable patch, I saw a few small raised dirt bags in the vegetable patch. At that time, I felt a little strange, probably because I had seen those cat graves in my childhood, and I was a little curious whether those small dirt bags could be the cat's graves. At that time, there were no tombstones in front of those small earthen bags, and I did not rush to find out what those small earthen bags were, but sat by the library window while checking the materials in the nearby library and observing whether anyone approached the small earthen bags. One day in late September, a female classmate walked into the vegetable garden with a dead cat in her arms, and I sat by the library window to see that the girl had dug a deep hole next to the little dirt bags, and she buried the cat in it. I observed that the female classmate didn't care if anyone around her was stopping her, and she was burying the dead cat with a complete appearance, so I concluded that the vegetable patch must be a school-approved place to bury small animals. Dr. Lin took a sip of water and said.

"Does this have anything to do with what happened so many years ago?" Xu Tian asked.

"Listen to me!" Dr. Lin took another large sip of water. "I wrote down the appearance of the female classmate, and then I found the female classmate, and I also found her dormitory, and I wanted to observe her movements, but after I ambushed the female classmate downstairs in the dormitory, I never saw the female classmate again. I could have found out the name, department, class, and phone number of the female classmate, but the female classmate disappeared. ”

"Did you report this to the school?" Xu Tian asked.

"It's not just about reporting to the school! I also called the police, and it was Lao Chen who took over the case at that time. However, the school did not admit the existence of the female classmate at all, and her student status was not found, and even the police went to the provincial Ministry of Education to check the root cause of the female classmate's student status, but still found nothing. In the end, the police thought I was vexatious, and since I was a psychiatric graduate, the police even took me to have a psychiatric evaluation. I'm not convinced! So I begged Lao Chen to investigate the female classmate's household registration, as long as the female classmate's household registration is located, I will definitely be able to find out the truth. Lao Chen was very conscientious, and he cooperated with my request, but as a result, the female classmate's name and mobile phone number did not exist at all, and even the female classmate's ID number did not correspond. Dr. Lim said.

"Are you sure that the information about the female classmates you investigated at the school at that time is correct?" Xu Tian asked.

"My perception of myself is very clear, and this incident is the fuse that I came into contact with the ruling Tai Sui. In the end, the police were very helpless, Lao Chen was responsible for his work, and once wanted to take me for a psychiatric evaluation, but I underwent all the humiliating examinations, but fortunately, I was proved by the hospital to be a normal person at that time. After that, I went to Lao Chen alone, and I repeatedly emphasized my findings to Lao Chen, and I even told Lao Chen what happened in my childhood. When Lao Chen heard what I said, he began to pay attention to the incident, but under the conditions at that time, because the identity of the female classmate could not be found out at all, which was confirmed by the police, Lao Chen could not file a case against me. But Lao Chen already believed in what happened to me a little, so Lao Chen used other time to help me find the female classmate. Dr. Lim said.

"Seven years ago, the real-name system was not implemented for mobile phone numbers, and at that time, female students could use the mobile phone number handled by other people's ID cards, but they should be able to find out when the mobile phone number was cancelled." Xu Tian said.

"Lao Chen used his position to go to the business hall to check the mobile phone number, but it turned out that the mobile phone number was used by another person, and the person who used the mobile phone number became our only suspicion at that time." Dr. Lim said.

"Who is that?" Xu Tian asked.

"It's a girl in that university, and it's because of this result that Lao Chen insists on believing me." Dr. Lim said.

"The missing female classmate has a dormitory, right? What were the results of your investigation in the dormitory? Xu Tian asked.

"The dormitory of that university is a two-person dormitory, but unfortunately, the information I found was that the missing female classmate had a dormitory of her own, and her roommate had gone abroad to study before I started to investigate the school, and the school had not allocated an empty bed to anyone else." Dr. Lim said.

"It's too coincidental, isn't it?" Xu Tian asked.

"That is! We are all college students, and the dormitory at school has always been very tight, and as long as there are vacant beds, we will definitely allocate beds immediately, which is basic common sense. Dr. Lim said.

"What does the school say about this?" Xu Tian asked.

"The statement given by the school surprised me and Lao Chen, according to the dormitory manager, no one dared to live in that dormitory, so it has not been assigned." Dr. Lim said.

"Why?" Xu Tian asked.

"One of the reasons why it's very old-fashioned is that the dormitory manager said that the dormitory was not clean, which means that it is haunted." Dr. Lim said.

"That's a bit ridiculous! But since that's the case, there must have been an incident in that dormitory, right? Xu Tian asked.

"The dormitory manager also confessed to us about this, and it is said that the people in the dormitory next to it often hear a sound similar to a baby's cry coming from that dormitory, and it is a very terrifying cry." Dr. Lim said.

"It's also possible that the female cat has that terrible baby cry when she is in heat." Xu Tian said.

"There is surveillance in the hallway of the dormitory, and it can be determined that there are no cats in that dormitory, and no one has cats." Dr. Lim said.

"You said at the beginning that you saw the female classmate bury the dead cat in the vegetable patch, isn't that cat from the dormitory?" Xu Tian asked.

"Of course Lao Chen and I will investigate the cat, but when we dug up the cat's grave in the vegetable patch, I was dumbfounded, and it was not a cat at all, but a rotten pumpkin." Dr. Lim said.

"You may have fallen into someone's trap, someone is seducing you." Xu Tian said.
