"Are you doubting me? As for the key, because my colleague in 601 upstairs is very good friends, I gave him the key before he went on a business trip so that I could take care of it in case of emergency. Pen? Interesting? Pavilion wWw. ｂiquge。 info" Mr. Jin explained.

"I don't mean anything else, don't get me wrong." Xu Tian looked a little embarrassed in the face of Teacher Jin, who was not shocked.

There was a dull sound of going upstairs at the stairs, and a boy about 1.9 meters tall, with a fat body, eyes and a very round beer belly, walked up.

The boy went straight to 501 and was about to knock on the door, Xu Tian and Sitong both sighed, and the two seemed to have seen through the boy's origin.

"Wait a minute! Are you here for help? Xu Tian asked the boy.

"Huh?" The boy who was about to knock on the door looked at Xu Tian, looking confused. "You are?"

"Don't move, I'll deduce, you're here for me to help you find a girlfriend, right?" Xu Tian said with a pretended mysterious look.

"Are you Mr. Detective in Mr. Wang's mouth? I did entrust you to help me find a girlfriend, do you still know fortune telling? The boy looked at Xu Tian with a shocked look.

"That ......," Mr. Jin's voice came from the top of the stairs. If it's okay, I'll go first. ”

"Oh! I'm really sorry just now, please do it! Xu Tian said politely.

Xu Tian turned his gaze to the boy, who was already sitting at the door, looking very struggling.

"Tell me what happened!" Xu Tian asked.

"My name is Du Hui, my girlfriend's name is Xia Lan, we made an appointment to meet yesterday, but she hasn't shown up this morning, and the phone is turned off, so I can't contact her."

"How long have you been in a relationship?"

"For almost a year, she went out a lot because she liked to play, and I knew that there were a lot of boys around her, but I felt that sooner or later she would be able to devote herself to me."

"Your girlfriend's name is Xia Lan? Is she a student at this school? ”

"Of course, she is from the music department, and there is an important performance tomorrow, I wanted to be able to accompany her well before her performance, but now I can't find anyone with her, although she often goes out to play, but she will definitely not lose contact with me, this situation is too abnormal."

"When was the last time you contacted Xia Lan?"

"Last night."

"Exact time?"

"I'll see." Du Hui took out his mobile phone and flipped out the address book. "The phone was connected at 9:40 last night, and the call lasted for three minutes."

"Are you sure it's Xia Lan herself who answered the phone?"

"I'm pretty sure it looks like someone knocked on the door while we were on the phone, and then she said hang up first and contact me tomorrow."

"Do you know where Xia Lan's residence is?"

"She doesn't live on campus and rents an apartment outside, but she doesn't live there often."

"Did you go to her today?"

"I went there in the morning when I found out that she turned off the phone, but the apartment has been vacated by her, and now someone else has rented it."

"Do you have a picture of her?"

"My phone is full of pictures of her." Du Hui flipped out the photo album and said.

Xu Tian looked at it, and sure enough, it was the girl who disappeared in 503, and it was exactly the same as the girl described by the first three clients, and these four clients were looking for the same person.

"Do you know all the people around Xia Lan?"

"I've never asked, and she doesn't like to be asked, so all along, I've turned a blind eye, because I love her so much, no matter what she does, I can't do without her, I've been wronged, I've been angry, but ...... But when I see her innocent appearance, my heart will soften, and when I hear her gentle voice, my anger will disappear. Charan is like a magic that can extinguish all my anger and make me feel more in love with her, I know it's sick, but I really can't live without her. ”

Xu Tian and Sitong listened very awkwardly, and neither of them seemed to be able to understand Du Hui's mentality.

"Can you leave me Xia Lan's identity information? It's easier for me to investigate. ”

"No problem, please find Xia Lan quickly, I feel that something must have happened to Xia Lan, otherwise she will definitely not lose contact with me."

"When was the last time you saw each other? I mean meeting, not calling. ”

"About a month ago! Because Xia Lan has an important performance tomorrow, she told me that she is going to retreat and practice this month, so she won't let me disturb her, and we just talk on the phone once a day. ”

"During this month, you haven't noticed anything unusual about Xia Lan?"

"If it's abnormal, I think Xia Lan is a little cold to me, I used to be very enthusiastic when I talked on the phone, and during this month, Xia Lan seemed to be in a hurry to hang up the phone every day, especially yesterday, and hung up in a hurry."

"I see, if you think of any useful clues, remember to let me know in time."

"Okay, you must find Xia Lan as soon as possible, my feeling will not be wrong, Xia Lan must have an accident."

"I'll do my best, you can rest assured."

Du Hui staggered to his feet and walked downstairs with heavy steps.

"Xu Tian." Sitong said. "These four people are looking for the same girl, do you think this girl described by Du Hui will be the real identity of the girl?"

"Let Siyan help you check it out, music department, Xia Lan."

At this time, Siyan was reading a book in the house, and when she saw Xu Tian and Sitong walking in, Siyan closed the book and beckoned Xu Tian to sit down.

"What the hell are you saying about me in front of my students? Since this morning, my business has been in a constant stream! Xu Tian said teasingly.

"I just created a detective in front of them, and of course, I made up most of the story." Siyan said proudly.

"Although I don't reject this, it's better to be realistic, I don't want to be a legendary character!"

"That's right, if you solve this case, there will be real cases in the future."

"You can help me check Charan first! Music department, there is a performance tomorrow, and I have a photo too. ”

"I'll help you ask."

While Siyan was inquiring about Xia Lan, Xu Tian took out his mobile phone and glanced at Xia Lan's photo again, and the first client, Shao Xiaowen, sent a screenshot of the video that made Xu Tian feel very curious, and Xu Tian enlarged the photo to view. This time Xu Tian moved his gaze to the background of the photo, in addition to Sitong who had just gone out, there was also the appearance of the 504 homeowner entering the door, this person who was opening 504 was indeed the real homeowner of 504.

Hey? Xu Tian put his eyes on the head that poked out of the staircase, it was a man, and looking at that posture, he should be going upstairs, Xu Tian felt that this man was ......

"Ahh Decedent! This man is the man who died in 504. ”

"Xu Tian." Siyan hung up the phone and said. "That Xia Lan is indeed the real identity, there is indeed a Xia Lan in the music department, I asked the teacher of the music department, and I showed her the photo, this girl is indeed called Xia Lan."
