Out of the police station, I took a taxi back to school, it was already noon, Xue'er had been missing for sixteen hours, walking back to the dormitory, I had been praying, Xue'er, you must not have an accident, I will definitely find you as soon as possible.

Back in the dormitory, the three people in the dormitory were there, the dormitory chief was reading a book, Tang Long was still lying on the bed, holding his Pad in his hand, watching his TV series with relish, Sun Hou was still playing computer games, and from time to time he popped out a national scolding, the dormitory director saw me coming back, he put down the book in his hand, and was just about to open his mouth to talk to me, I made a silent gesture to the dormitory director, and then waved his hand to signal him to come out, the dormitory director did not speak, I gestured to tell him that I was waiting for him outside.

After waiting for about five minutes, the head of the dormitory stood in front of me dressed neatly, I looked at him, and then motioned for him to follow me, the head of the dormitory followed me silently, and after leaving the door of the dormitory, the head of the dormitory asked me: "Why did you get out of the hospital, why are you looking for me so mysteriously?" I looked back at the head of the dormitory and said, "I'm fine, except for a little discomfort in my throat, nothing else is serious, I came out of you because I wanted you to do me a favor." The head of the dormitory asked me suspiciously, "What do you want me to help with?" I turned around and walked on, then said to him, "Help me restore the scene!" I clearly felt the footsteps of the head of the dormitory behind me pause, I looked back at him, and then said to him: "I have gone to the police station to report the case, the police will come to me in the afternoon, I think they should go to investigate the scene, but yesterday's heavy rain should have basically destroyed all traces, I hope that when the police come to investigate the scene, you accompany me to restore the scene, because I have already gone to investigate there before the rain, and I sorted out all the clues there last night, I already have a rough conjecture in my mind, I want you to accompany me to verify it when the time comes, it will be of great help to find Xue'er's traces, are you willing to help me? I looked at the head of the dormitory with expectant eyes, and the head of the dormitory looked at me a little evasively, and when I saw that he thought for a moment, nodded, and agreed to my request.

At one o'clock in the afternoon, I had lunch with the head of the dormitory in a restaurant, and not long after eating, the phone in my pocket rang, and I picked up the phone casually to answer.

"Hey, hello." A woman's voice came from the phone, and I asked into the microphone, "Hello, I'm Xiao Han, who are you?" The woman on the other end of the phone said: "Hello, I am a police officer from the police station of City C, my name is Lan Meng, you can call me Officer Lan, responsible for the security of your area, you reported this morning that Ling Xue, a student from class 152 of the Department of Biology of University A, is missing, we need to find you to understand some information, is it convenient for you now?" I said into the microphone, "Yes, I have time now, you can come to me at any time." Officer Lilan's voice came over the phone

"Okay, we'll be at your school around half past one in the afternoon." I said into the microphone

"Okay, no problem, I'll wait for you at the school gate at half past one." After speaking, the other end of the phone hummed softly and hung up the phone.

I looked at the head of the dormitory who was eating across from me and said, "The police are calling, they will come to our school at about half past one, now I will tell you about my findings and conjectures, and how you will cooperate with me at that time." After speaking, the head of the dormitory put down the chopsticks in his hand and quietly listened to me narrate and analyze the discovery of the day and his own conjectures.

Time unconsciously in my narrative reached half past one, I and the head of the dormitory came to the gate of the campus, not far away a policeman drove towards us, stopped in front of us, a tall, a female police officer in a police uniform walked down, followed by a middle-aged policeman, and the little policeman who made a note for me today, the female police officer walked up to us and asked us, "Who is Xiao Han?" I stepped forward and said to the female officer, "I'm Xiao Han." The female police officer looked at me and then said to me, "Hello classmate, I'm Lan Meng who called you today, Officer Lan." We're here today to find out what happened, and we need you to take us to the place where you found your girlfriend missing. I nodded in understanding, and then said to Officer Lan, "This is my dormitory master next to me, and I may need his help today." The female officer looked at him and said to me, "No problem, you can take us to see where your girlfriend disappeared." I nodded, then turned and walked towards the spot where the clues to Cher's disappearance had been found.
