"Look, can you leave your contact information, it will be convenient to contact you in the future," Yuan Qi stood in front of the manager and said.

The manager took out his business card and handed it out, saying, "This is my business card, and my surname is Feng." ”

Yuan Qi took the business card in the manager's hand, looked at it for a while, raised his head, and said, "Well, okay." ”

"There's my contact information here, if you have anything to ask, call here, there's my phone number on it," the manager said, pointing to the phone number on his business card.

"I see, you go get busy first."

The manager turned and entered the office. Yuan Qi walked into the elevator and went upstairs, entered his room, turned to face Zhao Deqing who was standing behind him, and said, "I have some things to think about, so if I don't have anything to do, go into my room and rest." ”

"Okay, Master, you should rest earlier, too."

"yes, I see."

Zhao Deqing exited Yuan Qi's room and closed the door, entering his room. Yuan Qi stood in this room, paced up and down in his room, sat on the sofa again, took out a pack of cigarettes and shook out a cigarette in his mouth, took out a lighter and lit the cigarette in his mouth, took a puff and spit out the smoke, sat on the sofa and smoked while pondering, thinking of the scene when the white swallow entered the elevator. At twelve o'clock in the middle of the night, the white swallow lying on the bed was tossing and turning, unable to sleep, and the head was in unbearable pain, suddenly sitting at the head of the bed, with an exclamation, stretched out his hand and touched the switch on the wall, turned on the electric light, and the room was bright. After the white swallow got out of bed, she put on her clothes and shoes and slowly walked out of the room. After walking out, the white swallow walked in the long corridor and stood in front of Liao Hongmei's door for a long time before slowly leaving. Walking through this long corridor and standing in front of the two doors of the elevator, perhaps his head was starting to hurt again, banging his head on the two doors of the elevator. The two doors of the elevator opened, and Bai Yanzi walked into the elevator. Standing in the elevator, Bai Yanzi's body was shaking, and he kept shaking his head, looking listless, and the elevator went down to the first floor and two doors opened. The white swallow slowly walked out of the elevator and out of the hall. An hour later, the white swallow slowly walked into the hall again, walked into the elevator, and stood in the elevator. When the elevator ascended to the second floor, the two doors of the elevator suddenly opened. At this time, an old lady and a little girl walked in from outside the elevator. Bai Yanzi looked at the old lady and the little girl standing behind her. At this time, the old lady smiled strangely at him, which made people shudder. Looking at the little girl beside the old lady, her face was expressionless. The two were pale and bloodless. At this time, Bai Yanzi showed a look of fear on her face, and hurriedly pressed the button next to the elevator, and the two doors of the elevator opened again. The white swallow was in a hurry to get out, and walked very slowly in the long corridor on the second floor. The long hallways were dark, and there were no lights to illuminate them. As he reached the end of the hallway, he suddenly heard the laughter of a little girl behind him. When he turned around, he found that this little girl was standing behind him, wearing a floral dress, holding a leather ball in both hands, looking up at the white swallow, and said, "Uncle, come and play with me." Then he let out a giggle. Bai Yanzi looked at the little girl standing behind her, her face was pale, and there was a pool of blood where she was standing, and a strong smell of blood came to her nose. The white swallow pushed the little girl away and ran through the long corridor, looking left and right. He was panting for breath when he stopped. Strange laughter echoed around the hallway, and when he looked behind him, the little girl was nowhere to be seen. In the midst of the echoing laughter, the little girl's voice was heard.

"Uncle, come on, play with me."

"No, no, ah," Bai Yanzi held his head in both hands with an extremely frightened expression, as if the whole person was about to collapse. Go straight to the two doors of the elevator and press the button to open the door next to the elevator. At this moment, the little girl appeared in front of him, slowly approaching, and suddenly the sound of exclamation echoed all around. Bai Yanzi hurriedly pressed the button next to the elevator, the two doors of the elevator opened, and Bai Yanzi hurriedly entered the elevator. When the two doors of the elevator were closed, I saw the little girl's arm stretched in, the arm was clamped off by the closed elevator door, the broken arm fell, and the blood sprayed the white swallow's body, and the little girl outside the elevator screamed in horror, and the cry of the loss of voice came into the elevator as if it was heartache. Bai Yanzi took off his clothes, kicked and stepped on his feet, and kicked the broken arm around, maybe he was too flustered, calmed his expression, the elevator returned to normal, there was no blood on the ground and no broken arm, and his legs were weak and he sat on the ground, which was a scene with the surveillance video in the elevator that Yuan Qi saw, which made an association. Yuan Qi suddenly opened his eyes, looked at the cigarette that was about to finish smoking in his hand, took another big breath and spit out the smoke, threw the cigarette butt into the ashtray, got up and walked out of the door, stood in the long corridor, slowly walked to the two doors of the elevator, pressed the button next to the door, the two doors opened, and walked into the elevator down to the second floor. Yuan Qi walked out of the elevator, the second floor is different from the third floor, there is a light in the corridor on the third floor, but the corridor on the second floor is pitch black, there is no light; The rooms on the third floor are basically full of people, and this place gives people a lifeless atmosphere without the slightest popularity. Yuan Qi walked very slowly in this long corridor, looking left and right, taking out his mobile phone and turning on the flashlight, the left and right irradiation, these rooms were pitch black, obviously there had been no one living in these rooms for a long time. At this time, a flashlight light shot out of the stairwell, and a black figure walked out of the stairwell and walked in the corridor.

"Who is it?" Yuan Qi turned around and shot the flashlight of the mobile phone in his hand.

"Master, it's me, Zhao Deqing," Zhao Deqing stepped forward and stood in front of Yuan Qi and said.

"Deqing, it's so late, why haven't you fallen asleep?"

"I can't sleep, I think about it, I think there must be something strange on the second floor, but I can't find any reason, so I want to see the second floor."

"You and the teacher have the same idea."

"Master, what did you find?"

"I haven't found anything yet," Yuan Qi said after a long time: "In the corridor on the second floor, there is no light, and it is obvious that no one has come here to rent a room for the night for a while." In a huge hotel, only the second floor is empty, could it be that something has happened here? Tell me, what would have been the thing that made the entire second floor so empty? ”

"There are only homicides, and people die in this hotel."

After listening to Zhao Deqing's assumptions, Yuan Qi said, "Are there any other assumptions?" For example, the second floor is being renovated and cannot be inhabited for the time being. ”

Zhao Deqing illuminated the surroundings with a flashlight and said, "Master, come and see that there are no traces of decoration on the ground except for dust and confetti, it is obvious that it can be ruled out, only homicide." ”

After listening to Zhao Deqing's analysis, Yuan Qi nodded and said, "Well, if it's a homicide, then it will be in that room?" ”

Zhao Deqing looked around, his face was blank. Yuan Qi just smiled slightly, pointed with one finger, and pointed to the door of room fifteen. Zhao Deqing stepped forward and stood in front of the door of room No. 15, no matter how he thought about it, he couldn't figure it out, so he asked, "Master, how do you know that you are in room No. 15?" ”

"What do you see on the door?"

Zhao Deqing shone away with a flashlight, turned around and said, "Nothing." ”

Yuan Qi stepped forward and said, "Give the flashlight to the teacher." Yuan Qi took the flashlight, irradiated it in front of the door of room 15, then clamped the flashlight under his armpits, stretched out his hands and carefully removed the scrap of paper attached to the door, and said, "What do you look for?" He then used a flashlight to irradiate the marks on the scraps of paper. Zhao Deqing looked at the marks that had been pasted on the door, and then looked at the confetti left in Yuan Qi's hand, and said, "This is a seal." ”

"Yes, this is a seal, and the seal is used to protect the place where the crime was discovered, so the master can conclude that the murder scene is in this room."

"It's hard to find out in this dark night, Master, how did you find out?"

"We have seen the surveillance video, when Bai Yanzi was taking the elevator, the elevator suddenly stopped on the second floor, Bai Yanzi ran out for more than half an hour and entered in a panic, seeing that he must have been frightened by something so frightened, so he had an association, and went down to the second floor with a sense of curiosity, the second floor was empty and no one lived. There is only one person on the second floor of a huge hotel, and the door of the elevator is sealed to prohibit people from passing through. The first thing that popped into my mind when I stepped out of the seal was that there must have been a murder here. Let's make another assumption, if you are a murderer, you will not commit the crime in the corridor, it must be in a certain room, so you look around for clues, think of the seal before the aisle, look for each door, and find room 15, only to find that there are traces on this door, and there are no other doors, so you can conclude that the murder must have happened in room 15 on the second floor. ”

The next morning, Yuan Qi and Zhao Deqing waited in a nearby teahouse. Yuan Qi stood in front of the window and looked at the scenery outside the window, took out a pack of cigarettes and shook out one cigarette, then lit the cigarette in his mouth, and took a puff to exhale the smoke. Zhao Deqing sat in front of the card table next to him, drinking tea. After Manager Feng received a call from Zhao Deqing, he rushed to the teahouse they had agreed upon. Manager Feng entered the hall, stood in front of the two doors, and walked up the stairs. Manager Feng stepped into the hall of the teahouse and stood in front of them.

"Manager Feng, hello, since you are here, please take a seat," Yuan Qi turned to look at Manager Feng who was standing in front of him, threw the cigarette butt into the ashtray, and looked at Manager Feng after sitting down.

After Manager Feng sat down, he looked at Yuan Qi and Zhao Deqing who were sitting in front of him, and said, "If there is anything, you can ask." ”

"When I took the elevator down the second floor of the hostel last night, I saw that the second floor was unoccupied, and there were no street lights in the hallway. I just wanted to ask, what happened on the second floor that was seized? Yuan Qi looked at Manager Feng who was sitting in front of him and asked. However, Manager Feng seemed to have something to hide from this, and just said, "I don't know." ”

"I don't know," Yuan Qi sat in front of Manager Feng and observed Manager Feng's face, pondering for a long time before saying: "I know that these things are the most taboo for you business people, and it is normal to avoid talking about them, I understand this, but this matter is related to another case, you should have heard of the death of Bai Yanzi." ”

"I've heard of this, doesn't it mean sudden death?"

"It's not that simple, we're here to investigate the case of White Swallow. I would like to ask if there has been a homicide in room fifteen on the second floor. ”

"Since you said so, I don't have to hide anything, there is indeed a homicide in room fifteen on the second floor."

Yuan Qi nodded when he heard this, and looked at Zhao Deqing who was sitting next to him. Zhao Deqing, who was sitting next to him, asked, "When did this happen?" Tell us about the incident. ”

"At the end of May and the beginning of June, around five or six o'clock, there was a couple standing at the counter and renting a room for the night, and they stayed in room 15 on the second floor. The couple looked very affectionate, but in the middle of the night there was an argument, and the sound was so loud that almost everyone who lived here heard it. It's normal for couples to have arguments, and we don't take it seriously. The next day, when the cleaning aunt went to clean up, she found that there were a lot of blood stains on the ground, and the woman was lying motionless on the bed, but the man was missing, so we called the police. ”

"How's that woman doing?"

"I was stabbed several times, the murder weapon was a fruit knife, and we died of excessive bleeding when we broke into this room."

"You should know the name of the murderer."

"Cui Zicheng."

"Okay, take us to room fifteen."
