Liancheng only answered half a sentence, and then got to the point, and his serious attitude towards work made me dare not slack off: "Do you dare to marry?" Less dreaming. What happened to this Xu Xianan before he died? Are there any strange actions? ”

"Strange action—" I pondered for a moment before speaking, "I don't know what kind of strange behavior you are talking about, the police did not find any suspicious behavior before Xu Xianan's death, otherwise this case would not have dragged on for seven years." ”

"There must be something, it must be something that they overlooked. The first case always leaves the most evidence. ”

Listening to Liancheng's puzzlement, I shook my head and smiled mysteriously, looking at Liancheng's appearance, I knew that he must not know the case yet. I said, "The right time and place are not just about ancient wars. Lian Cheng frowned when he heard this, because he didn't seem to understand what I was saying, I paused and explained simply, "God can't help the bad guys." It was raining heavily on the night of Xu Xiannan's death, and the scene was washed clean with water. No evidence remains. ”

"Didn't the murderer have sex with the deceased? Can't DNA be measured? No, you know, even if there is no other evidence, as long as you have the murderer's DNA, you can still arrest people. Lian Cheng's face gradually became a little angry, and the tone of his voice became stiff, "What did they take the investigation of?" Is it fun? That's human life! ”

"Liancheng, calm down."

"Team Leader Murong, you listen first," Xiao Yan, who had been quietly flipping through the documents, finally spoke, he put down the kraft paper in his hand and looked at Liancheng's eyes full of anger seriously, "There is no murderer's sexual material left in the body of the deceased Xu Xianan. To be precise, Xu Xianan's Yin Dao was destroyed, and there is no way to verify it. The murderer was cruel and cautious enough, from hunting, eating the prey, destroying the corpse, almost step by step. The murderer played a game of nirvana, which made the criminal police lose before they even started. ”

For a moment, the whole office was silent, and the faces of the three of us were extremely heavy, and we couldn't understand why this case was so difficult to investigate. The usual procedure is no longer useful. There was not a trace left, except for a brutal death, and everything was taken for granted.

"There it is!" A flash of inspiration flashed through my mind, and I immediately stood up from the sofa and looked at Liancheng with joy on my face, "There are still doubts!" Liancheng, Zhang Zhi and Lu Zheming were handed over to you for autopsy, right? Lu Zheming! His death was different, he was killed! Dagger, no, it's a fruit knife! He has a fruit knife in his chest! ”

To my surprise, Liancheng was not happy because of my words, but his face became even more ugly, he said: "There are no fingerprints left on that fruit knife, Lu Zheming is not fatal because of the knife in the chest, the knife is very shallow, he died of excessive blood loss." ”

"Why don't we go to the equipment room tonight and keep watch."

"You're crazy! Do you want to die! Go yourself! We're not going to die with you, you ........."

"Xiaoyi!" Lian Cheng reprimanded, and turned to me, "Don't worry, let's go and check Xu Xianan first." ”

Directionless, we acquiesced to Liancheng's idea, and that was the only thing we could do. Liancheng, I, Xiao Yi, the three of us are divided into three ways, Liancheng will check the family of the deceased, I will go to check the classmates and friends of the deceased, and Xiao Yi will go to find the criminal police officer who took over the case seven years ago. The division of labor was clear, and we set off quickly.

The weather in ZJ is always so hot, the sun falls on the skin and burns, even in such bad weather, the streets are still full of vehicles, but there are only a few pedestrians. I could barely open my eyes in the sun wearing a sun hat, but the sweat came out layer after layer, and the shirt was wet and uncomfortable against my body, and I could vaguely see the tight skin under the clothes, and I didn't seem to know the young girl who occasionally looked at me. The closer I got to noon, the scorching sun became, and the faster I walked.

I'm going to Room 7, Unit 1, Yebei Community, Yebei Street, to find a middle-aged man from Luo Wei. Luo Wei is a professor at the University of Science and Technology, and he was Xu Xiannan's mentor when he was not a professor seven years ago, and he should know Xu Xiannan very well.

It took about half an hour from the bureau to Yebei Community. Standing downstairs in a unit of Yebei Community surprised me, I thought that Luo Wei, who was a professor at the Polytechnic University, lived in a high-end apartment similar to a villa with white bricks and blue windows, but in fact it was just an ordinary residential building. The high walls made of reddish-brown fire bricks, the railings of the stairs stained with heavy rust, the marble floor tiles with thick dust, and the walls that should have been painted white are also gray, and there are children's graffiti on them. I couldn't believe my eyes that there was a respected professor living in this simple, even dilapidated, residential building. It was quiet in the building, and I only stopped downstairs for a few seconds before walking in.

I found room seven and rang the doorbell. And the doorbell, at least not as bad as I thought it would be. The door was opened by a middle-aged man in home clothes, the corners of his eyes had drooped, forming three deep wrinkles, there was no hair in the middle of the top of his head, and most middle-aged men had a "Mediterranean" hairstyle, which was very common, his lips were a little thick, tightly pressed together, and the whole looked a little decadent and desperate, but the eyes embedded on both sides of the bridge of the nose were shining, adding a bit of sharpness to the whole person.

He stood in the doorway and looked at me for a few moments before he turned sideways to let me in, his gaze softening. He walked over to the only desk in the room and sat down, picked up his pen and looked at me. That's what he was supposed to be writing just now. He picked up and put down the pen, and then paused for two seconds with his fingers folded and said, "Is there anything wrong with my classmates?" If you have any difficulties, just say it, and if you can help, I'll be happy to help you. ”

I stepped forward and propped my hands on the desk in front of him and looked him in the eye carefully: "The professor misunderstood, I am not a student. But I do have something to ask you, and you're sure to be able to help. ”

Hearing this, his pupils shrank, but he was not in a hurry to promise anything, but asked, "Oh, I don't know how I can help you?" Who are you? How will I know I live here? ”

"Haha, Professor Luo is really humorous, just ask a science and engineering student and ask you where you live. As for who I am, can't Professor Luo guess? I looked at him with a smile and slowly pulled out my wallet and opened it for him. His face changed again, and this time the person who was puzzled was me: "What's wrong?" Professor Luo, you seem to be very taboo about the police, especially the criminal police. ”

"Really? Isn't that strange? Who wants to deal with the interpol? Officer Jun, I can call you that, right? His expression was not in a trance, he looked at me with a polite smile, as if everything had nothing to do with him, which made me feel that the emotions I saw in his eyes just now were hallucinations, he was very calm and confident, his attitude made me feel a little strange, but it was not strange, "Officer Jun is only twenty, younger than my students, what a good talent, I don't know what I can help Officer Jun?" ”

"Thank you for the compliment, and I don't need Professor Luo to do anything, but I imagine asking Professor Luo some questions, and I hope Professor Luo will answer them seriously."

"Ask, know everything, say everything."

"Good!" I raised my eyebrows and smiled, "Professor Xu Xia Nanluo, who died tragically seven years ago, know it, right?" So Professor Luo, can you tell me about Xu Xianan's past? ”

"Bang bang bang - "

As soon as I said this, there was a series of sounds of broken glassware in the back room. I stood up in shock, pointed to the back room and asked, "Professor Luo's house is still a guest?" Why don't you hide in the back room and not come out to meet the guests? Or is it something unseemly......"

Luo Wei also stood up from the leather chair and looked at the back room, and when I looked back, I saw his pale face, and immediately realized that something was wrong. Luo Wei's eyes were full of fear, and even his body trembled a little, so a bad premonition also rose in my heart. There is definitely something wrong with this Luo Wei. Seeing that Luo Wei looked at the back room in fear without any movement, and the whole person seemed to be pointed, I was not polite, and strode to the door to open the door.

"Nope! Don't open! ”

Luo Wei suddenly pounced on me, and I was hit by him against the wall, and my left hand, which was already not good, hurt again. I'm even more curious about that door at the moment, and I'm going to see what is hidden behind that door today. Although the criminal police have guns, they can't be worn at any time, but fortunately, the silver "ghost hunting gun" I have always worn on my body, and now it is a little useful. I took out the silver pistol hidden in my waist and pointed it at Luo Wei, and said in a cold voice: "What? What did you do that you couldn't let me see? If you're blocking me, you're obstructing the police investigation, and I can arrest you as an accomplice! ”

Luo Wei still obediently gave in a step, but he still warned me: "You can't open it!" Can't open! Absolutely not! ”

The more he is like this, the more I feel that there is a ghost in my heart, and I have to see what is behind it! I pointed a gun at him, scared that he would pounce on him like a madman for a while. I walked to the door again, the speed was not fast, the door was closed, and the people inside couldn't still run away, right?

"Crunch—" I opened the door. Luo Wei sat on the ground in despair like a deflated ball. I cautiously entered the back room, holding my gun in front of me. It was pitch black inside, and there was a musty smell, and the doubts in my heart were even stronger. Slowly moved to the window and pulled down the heavy curtains, and the room instantly flooded into the sun, and the darkness was dispelled without a trace. That's when I saw the furnishings in the house. The house was full of dust, so thick that it made people think that at least four or five years had not lived in it. There was a chair in the corner, the wood of the chair was starting to rot, and there were a few broken shapeless cups right next to the chair, and a gust of wind blew in through the window and I shivered, and the wind blew the bitter cold on my face. There is a black stain on the wall behind the chair, which makes it awkward to look at. There was nothing in the house!
