The chicken was offended

Lu Yifei rummaged through the bottom of a one-meter-long plant and found the key. The key was soaked in water and was dripping wet. It probably didn't take long for Old Wutou to water it around the floor.

I rubbed the key on my clothes and inserted it into the door lock, and I opened it easily. It was different from the stagnant feeling in my bedroom. It was obvious that someone occasionally maintained and oiled it.

The layout of each bedroom in the building is the same. There are four beds in the four corners of the room, and a long table with two tables put together by the window in the middle.Although there are not as many things in the boys' dormitory as the girls', they still make full use of the space. The changed clothes and shorts are piled up on the four chairs, like baobab trees growing in the tropical rainforest.Computers, glasses cases, and game consoles are piled up on a small table, and various power cords are tangled together.

The induction cooker and pots are stacked in the corner between the bed and the wall, in case old Wu suddenly checks his bed.There is a suitcase next to each bed, and Liu Zhengyang's suitcase is 30 inches in size.

The two people in this dormitory have already gone home, and the beds are empty.Liu Zhengyang's bed was on the west side by the window, while Zhang Bin was on the west side of the door.The furnishings in the dormitory seem to be the same as when Lu Yifei came to eat hot pot last time, but many things have changed.

He looked at Zhang Bin's bed.

There were traces of Zhang Bin lying on the bed that day, and the quilts were crookedly piled up, as if the owner of the bed was just going to the bathroom.There were still blood stains on the quilt by the bed, and most of the blood on the ground had been cleaned up, restoring the gray color of the floor tiles themselves.

On the day of eating hot pot, talking and laughing loudly, and drinking heavily, I never imagined that this kind of thing would happen. At that time, one of the people who made jokes together was accused of being the murderer, and the person who identified him was his closest classmate and brother. What an irony.And the real murderer hid behind his back and laughed wildly, watching their own people biting their own people with cold eyes, waiting for the time when their internal friction is over and committing another murder.

Lu Yifei sighed, the sun was still high in the sky in the evening.The humidity in the south is heavy, and the sun in winter is like a lamp in a refrigerator, which can only illuminate the light.He walked to the window sill, trying to open the window, to let out the stuffy feeling in the room.

He approached the window, unexpectedly kicked it to the bottom of the bed, and something popped out.

Police station.

Xiao He continued to add things to the case file in his hand on a whiteboard filled with the relationship between the characters and case analysis of the three cases.Yan Changhai supported the conference table with both hands, staring straight at the whiteboard.Wu Yong came back from the forensic doctor, sat quietly beside him, and lit a cigarette.

Wu Yong only took two puffs, "The time of death was around 7 o'clock, and the time of death identification was indeed delayed on purpose. This murderer's thoughts are so meticulous and terrifying."

Yan Changhai frowned, expressing agreement: "The mentality is amazingly stable, unlike ordinary people."

"Should we look at people with previous convictions? Repeat offenders are easier to get."

"No, I believe it was the constant crimes that made him grow."

"How to say?"

"In the beginning, he had to move the body after killing someone. The first reaction he encountered was to hide and cover it with a rain cloth and wait until it was completely safe before moving. But look at the third person," he pointed at Dong on the whiteboard. Yu's photo, "After killing someone, he even responded to the WeChat message leisurely for the deceased, making people play with applause. He was not afraid of being discovered when he committed the murder, and even enjoyed it a little bit before he was discovered. The thrill of escaping."

Yan Changhai could still form a picture in his mind. After a faceless figure committed the crime, Shi Shiran sat on the comfortable sofa of Dong Yu's house, sitting side by side with the deceased, caressing the remote control to turn up the temperature.

Wu courageously smiled bitterly, "It's more troublesome like this. You have a smart mind, are cautious about details, and have a bit of an anti-reconnaissance mind. It would be great if you walk on the right path."

Xiao He nodded in agreement, "I have read the case files dozens of times, and there are only a handful of flaws. If I were a student of Minghai University and knew there was a murderer in the school, I would have run home early."

Yan Changhai's eyes lit up suddenly, "What did you say?"

Xiao He was taken aback, recalling what he said 5 seconds ago and repeated it again.

Now Wu Yongyong also understood, and exchanged a glance with Yan Changhai, "The murderer must be a student!"

Only Xiao He looked left and right in a daze, "What do you mean?"

"Dong Yu returned to Minghai City halfway. His trip to the United States has not yet been completed. Originally, he could not return to China on his own initiative. In order to avoid dissatisfaction among other students, the school only notified a small number of students related to that project. Only a few students know it, we just have to ask his tutors to find out."

"It seems that the murderer has a lot of thoughts, and he will eventually make a mistake. There is no case in this world that does not leave traces."

Wu courageously went to contact the teacher of Minghai University.

At the same time, in bedroom 312.

Lu Yifei lowered his head and picked up the dark blue umbrella.The umbrella is very beautiful, with a dark blue check pattern, and the wooden umbrella handle is covered with pulp, with smooth wood grain, but it is a pity that the umbrella handle was cracked by him, revealing a seam.

He was about to put it down when a flash of light flashed through his mind. The feeling came unexpectedly and made his hairs stand on end.

It was as if the drumsticks were beating his heart loudly and violently.

impossible.There are some strange thoughts in my mind, yes, I must have followed the scene of the crime, so I am suspicious.

But he couldn't even convince himself with his own hands.

Holding the umbrella handle tightly with his right hand, he pulled out the slick knife silently with force, and his unbelievable face can be seen in the mirror on the slick knife blade.

"The murderer is very obsessed with killing people with a knife", "It's slightly longer than a scalpel, and the blade is cut on both sides", "The murder weapon is still not left at the scene", Lu Yifei's ears were filled with discussions one after another.

His head seemed to be covered with a layer of ice, and the cold air poured into his body from the top of the sky, but his hands were gradually sweating, almost slipping on the wooden handle.

There were footsteps at the door.

creak.

Lu Yifei calmed down and kicked the umbrella under the bed.

"I've been waiting for a long time." Liu Zhengyang looked at him through the lens, and found that he was standing there with some doubts, "What's wrong."

"It's nothing, I'm thinking about Zhang Bin." Lu Yifei gulped down his saliva, pretending not to see Liu Zhengyang locking the bedroom door with his backhand.

"Then... what do you think?"

"Zhang Bin is innocent... Although I don't know why someone caught Zhang Bin and made him choose to kill himself, Lin Quan was led by a person with ulterior motives to frame Zhang Bin and force him to commit suicide. "

"Oh? Then who do you think is the most suspect? Why can't it be someone with surgical experience who killed three people? Zhang Bin has performed many surgeries on people in small clinics." Liu Zhengyang took a step forward with his hands behind his back, The corners of the mouth are raised, and the lens is glowing with a cold metal light.

I see!On the day of Zhang Xinhua's death, Zhang Bin performed an operation on someone illegally, so he couldn't say anything, and he couldn't prove that he was not in the art building.

Lu Yifei took a step back unconsciously, unlocked the fingerprint lock of the smartphone with his hand in his pocket, and was stunned the next second, hating why it wasn't a nine-button tablet, and his touch typing skills were completely useless.

Find the emergency call button with the feeling of your fingertips, and then you can only rely on God's blessing.

"You are the same person as me. I have seen you save a girl. You are usually indifferent, but once something happens, a sense of justice suddenly erupts in your chest, right?" Liu Zhengyang said to himself, "But With you like this, you have to get involved here and there, which makes people upset."

"You've already found out."

This Liu Zhengyang, who was completely different from the way he helped him out while eating hot pot, made Lu Yifei feel strange.

Liu Zhengyang put his hand to his mouth, like a whisper in class: "My knife."

"It's really you!" Lu Yifei couldn't accept it at all, "Are you crazy? Think of yourself as a god and judge everything. What right do you have to deprive others of their lives?"

"Haha, I guessed that you would understand. You are another me in this world, so how could you not understand? It's really cool to implement a just ruling, and you should feel it too." Suddenly grabbed Lu Yifei's hand With his left hand, pressed against his own bed, pulled out a plastic buckle from his sleeve to fasten him with the metal frame of the bed, and when Lu Yifei opened his mouth wide to call for help, he stuffed a ball of rags into his mouth.

Lu Yifei was suddenly under the control of others, and a chaotic cry came from his throat, but the sound could not even penetrate the dormitory.

"Shut up," Liu Zhengyang pushed his glasses, his throat was rarely hoarse, "Before you meet Teacher Zhang and your classmates, you can still listen to the story. How about it, am I being nice to you?"

Police station.

Officer Wu called back and looked at several staff members present, "I've confirmed that, including the mentor, only five people know about Dong Yu's return to China, and one of them is the first discoverer of Dong Yu's case, Ji Ji." Xing, two girls from civil engineering, both of them had a meeting in the project company in other provinces on the day of the incident, many people can prove it. There are also two students from the Department of Management, one named Liu Zhengyang and the other named Tang Qinglan .”

Xiao He scratched his chin with a marker, "I remember it was written in the case file that Lu Yifei was seen by the murderer who committed the crime for the first time. Classmate Lu has been working on this case. Since the murderer is a student, it is impossible not to know that he is providing us with clues." , but the murderer hasn’t attacked him until now. Isn’t the murderer very cruel, why didn’t he attack him, is it because Lu Yifei has a close relationship with him?”

Lao Li was listening silently with a tea mug, and said hesitantly: "This Liu Zhengyang seems to be in the same dormitory building as Lu Yifei, and he lives quite close. I made the notes for him that day." After Zhang Xinhua's body was found One day, I got up early to go to the male dormitory of Minghai University to take notes, no wonder the name sounded familiar.

"Something happened to Lu Yifei." Yan Changhai clutched his cell phone. He and Lu Yifei had agreed to keep in touch 24 hours a day, but now the other party's cell phone was turned off.

"Let's go to Minghai University." Wu Yong ordered.
