During the day at work, I brought the disc with Yang Qianyun's message to the police station. I wanted to hear the opinions of my other colleagues in the office. If they assisted me in investigating this matter, I thought things would be much easier to handle.

　　I had made up my mind that if I didn't get to the bottom of what the girl named Yang Qianyun had said in the disc, I would keep feeling extremely uneasy.

　　At Zigu Road Police Station, there were three police officers handling cases: me, Chen Hao, and Jiang Tao. Around eight o'clock in the morning, the two of them sauntered in together.

　　"Come on over, guys! I've got something good for you to listen to!" I didn't reveal what it was right away, just wanting to see their reactions.

　　The two of them crowded around me, thinking I was going to discuss some movie with them. They were all excited. I clicked the mouse lightly and played the prepared disc on the computer.

　　This time, I skipped the songs at the beginning, and Yang Qianyun's voice suddenly jumped out: "Hello! I don't know who you are, but please listen to what I have to say. I'm an 18-year-old girl. A month ago, I played the 'Ouija board' game with three roommates, and something went wrong in the middle. Later, my three roommates died in mysterious circumstances one after another. I'm so scared. I suspect it's an evil spirit at work.

　　I told my relatives, but they didn't believe me and even wanted to send me to a mental hospital. Please save me. My name is Yang Qianyun, and I live at Unit 404, 2nd Floor, Building 44, Huayuan Community..."

　　I paid close attention to their reactions. They had joined the police station a few years earlier than me, so I thought they might know something. I saw their initially smiling faces instantly turn somber, their eyes go blank, and then fear filled their expressions. Without a word, they went back to their seats.

　　The office suddenly became filled with a heavy and oppressive atmosphere.

　　"Hey, what's wrong with you two? Did you see a ghost in broad daylight?" I muttered unhappily.

　　It was as if they hadn't heard me. They simultaneously rummaged through their drawers and started busily working on some files.

　　Normally, they were never this enthusiastic. I walked over to Chen Hao. He was a cheerful guy who always had something to say.

　　"What are you scared of? Do you know something about this case?" I stared at Chen Hao and said.

　　Chen Hao was stunned for a moment and then said, "Wang Jie, I advise you not to ask any more questions. Forget about this case. Getting involved won't do you any good."

　　"Why?" I almost screamed hysterically. "You have to tell me why!"

　　Chen Hao didn't say anything else and left his seat and went out. I turned to Jiang Tao, but he ignored me. No matter what I said, he just acted as if I wasn't there.

　　I instinctively knew that this case was truly extraordinary. Although I had been at the police station for more than two years, I was the most junior one. Clearly, before I arrived, they had come into contact with Yang Qianyun's case in some way. But they were intimidated by a force they couldn't resist and didn't dare to get involved in Yang Qianyun's matter anymore.

　　What kind of force was it?

　　In broad daylight, in the office, I felt a chill run down my spine and goosebumps cover my whole body. This force could only be explained as a supernatural one. Otherwise, it wouldn't have made several police officers so scared that they didn't even dare to mention it.

　　A surge of passion rose in my heart. Yes, I had been a bit fearful because of this mysterious force recently. But my curiosity drove me to want to get close to this force and uncover this secret.

　　The unknown was the most terrifying. Only by understanding the whole story of Yang Qianyun's case would my fear disappear. Ever since I applied to the police academy, I had had a belief: to fight against dark forces to the end. For this, I wasn't afraid of death, so what else was there to be scared of?

　　A heroic belief grew in my heart. I clenched my fists and said to myself, "I'm going to take care of Yang Qianyun's case!"

　　At 9:50, I noticed that Chief Li entered his office, so I hurried over.

　　"Chief Li, there's a case I'd like to ask you about!" I said respectfully.

　　"Go ahead," Chief Li said warmly. He liked it when his subordinates discussed cases with him.

　　"Has our station ever received a case from a girl named Yang Qianyun? She said she encountered a ghost."

　　Chief Li's warm face instantly stiffened. He silently took out a cigarette and offered it to me.

　　He then took out another cigarette for himself. He only smoked occasionally, and I could tell that this pack had been opened for a while as it had a musty smell.

　　Chief Li took out his lighter and lit it for a long time before finally getting the cigarette lit. He took a puff and then realized the cigarette had gone moldy.

　　"Have mine," I offered Chief Li a cigarette. It was a local brand, not expensive, just twenty bucks a pack. It was given to me by someone who came to handle some business.

　　Chief Li took a few puffs and then started to talk. "Three years ago, not long after I became the chief here, a girl in a school uniform came to report a case. She had a very pretty face, but she looked extremely frightened.

　　She was Yang Qianyun, a senior student at Hongcheng City No.1 High School nearby. She said her three good friends had died and that she was going to die too. She begged us police to protect her."

　　"I poured a cup of tea for Yang Qianyun and calmed her down. Then, through slow conversation, I finally learned the whole story. It turned out that a month before, right before the first mock exam for the college entrance examination, Yang Qianyun and her three classmates played a spirit-summoning game in the classroom, hoping to know their mock exam scores."

　　"These four students were all girls, named Yang Qianyun, Meng Qingwen, Zhang Xiaoyu, and Xu Yiran. After evening self-study, instead of going back to the dormitory, they pushed two desks together. Then each of them took a corner and stared intently at a saucer placed on the desk, which was upside down on top of a newspaper.

　　Yang Qianyun took a colored pen from her schoolbag and marked a red downward arrow on the saucer. The four girls all had extremely solemn expressions, showing that they were under quite a bit of psychological pressure from playing such a terrifying game."

　　"Yang Qianyun was the leader among them, and it was she who introduced the game. She explained the rules: You have to be sincere! Everyone put your hands on the saucer and silently chant 'Disc spirit, disc spirit, come out quickly.' At this point, you'll feel your hands move involuntarily. Don't be afraid; it means the disc spirit has manifested. You can ask any questions you have.

　　But the game must be finished before midnight, and it can't be interrupted manually in the middle. As for what would happen if it went past midnight or was interrupted manually, Yang Qianyun didn't know. She had only heard from a senior who had played the Ouija board game that if something went wrong, what was summoned wouldn't be the disc spirit but an evil spirit, and then those who played the game would be cursed by it."

　　"Xu Yiran, who was the most timid among the four girls, felt something blowing against the glass window at that moment and screamed in fear. She didn't want to play anymore. But the other three wanted to continue and persuaded her that once they finished playing, they could know their scores for this mock exam in advance.

　　Xu Yiran was a girl who didn't do well in exams. Every time she took a test, she was full of anxiety and gave it her all, worried that she would disappoint her parents and teachers. Persuaded by her classmates, she had no choice but to keep playing."
