"If the murderer is sure that he is using the secret room to confuse us, there is no need for him to create other strange incidents, which would be redundant. Just like You Lu's paintings, the chamber itself is simple, but it is associated with all the other strange times, some people are afraid, some people are disturbed, and then the murderer's continuous provocations and warning messages attract attention, and the case becomes complicated. Shen Cheng said.

Shen Cheng glanced at the room: "If he is good at using simple methods to create complex cases, perhaps, I want to understand why there are no traces of blood left in this room." I'm going to do the actual deduction. "Actual deduction is also a very common method used by investigative agencies.

On that day, when Shen Cheng and I were competing against the two-headed man, Shen Cheng asked his men to conduct an experiment, so as to deduce the position of the murderer who pushed down the big stone at the midnight construction site, the weight of the stone, and the force used. Half an hour later, everything was ready.

"This painter, when he committed the crime, probably thought that he was making art." Shen Cheng pointed to a layer of plastic transparent film and an absorbent blanket that had been laid on the ground and said, "This is his canvas." ”

At Shen Cheng's request, the police went to find a large piece of plastic transparent film and a large blanket with absorbent function, the transparent plastic film was spread at the bottom, and the absorbent blanket was spread on top of the plastic film paper. Shen Cheng held a human-sized dummy and a saw in his hand.

Shen Cheng took the dummy and walked to the place where Rena fell, he pressed the dummy's head from behind, and put the saw on the dummy's neck. At this moment, Shen Cheng seemed to have turned into a perverted murderer, and the saw in his hand quickly moved left and right, and soon, the dummy's neck was sawed open.

Shen Cheng asked for a spraying device to be placed around the neck of the dummy, which was filled with paint. As soon as the dummy's neck was sawed open, red paint sprayed out like blood. When a person's neck is slit, blood will inevitably spill out in the form of a spurt, and if it falls on the ground or on the wall, it will show a fog-like trace.

My heart was beating fast, because I saw Shen Cheng as You Lu. You Lu's facial muscles were severely distorted, the corners of his mouth were raised, and his fanatical expression was revealed. The blood-red paint continued to spray, and soon, the dummy's entire head was sawed off by Shen Cheng. Shen Cheng held his head in one hand and pointed to the ground with the other, and began to explain.

"The blood fell on the absorbent blanket, and the impermeable plastic film underneath the blanket, after committing the crime, he rolled up the plastic film and the absorbent blanket so that the blood would not fall to the ground. When he was done, he left through the window and locked it from the outside. Shen Cheng's words were fast: "The garbage truck that the drunk man hit was the one he used to hold all the tools of crime." ”

Shen Cheng said that he went to that neighborhood to observe, although it is a downtown area, but there is not a lot of garbage. Cleaners clean up every day, and the garbage on a street generally doesn't make the garbage trucks smell stinky. The drunk man said that the smell of the garbage cart he hit was unbearable.

Shen Cheng speculated that after committing the crime, the murderer rolled up plastic film and blankets and threw them into the garbage truck, and the head of Rena was thrown into the garbage truck. The stench is to keep people who walk at night to avoid it, and also to cover up the smell of blood. Bumping into a drunk man is beyond the expectations of the murderer.

didn't take action against the drunk, because he was afraid of another incident.

"There are other ways to leave no blood, and I'm not sure if that's the murderer's method. But if our speculation comes true, You Lu is the murderer, and he may be using this simple way to construct a mysterious and mysterious case. Shen Cheng said.

I asked Shen Cheng what his plans were next, Shen Cheng thought about it and said that our time may be running out, he has always felt that the murderer will make a big move in the short term, and he decided not to waste any more time on the woman in red case, we have done all the speculations that can be made, and now there is only a lack of evidence.

After such a long time, the traces disappeared without a trace, and the garbage truck was missing, and the evidence that Shen Cheng said was the murderer's confession. He decided to arrest You Lu first, and then interrogate him, after all, all the suspicions were pointed at You Lu. Shen Cheng immediately made a decision and said that we would go to City B tomorrow, and solved the last mystery: why did the bus disappear out of thin air under people's noses.

Instead of going back to the hospital, we went to the police station. Zhao Da didn't think about it as much as us, he already subconsciously thought that all our speculations were correct, and he was asking the police to record the suspects and criminal methods we speculated into the file.

I kept frowning, and Shen Cheng asked me if I still had any doubts.

I nodded, I had two concerns. One is why the murderer chose Rena to attack, and when we were in the border provinces, someone deliberately used Rena's head to scare us. Another is Meng Ting's move, if Meng Ting and You Lu have problems, Meng Ting shouldn't have put away the color block abstract painting that You Lu threw away later.

When You Lu was painting, he was already surrounded by an artistic atmosphere, and he didn't even notice it when I went outside his studio. That painting is revealing himself to himself, which is also the possible reason why You Lu deliberately threw away that painting. If Meng Ting and You Lu were in a gang, Meng Ting should no longer do the thing of biting her own people.

Shen Cheng said that the mastermind behind the scenes may have understood the psychology of Uncle Yi. Uncle Yi has never been able to trust other people, including Uncle Man, which will allow Rena to get close to Uncle Man. A few years ago, several coffins appeared in the Kuta Desert, which may have been deliberately arranged by the mastermind behind the scenes.

Everything is to make Uncle Yi think that Uncle Man has a problem. However, things don't go according to people's wishes, and Uncle Yi doesn't seem to be completely suspicious of Uncle Man because of this. That operation, on the contrary, contributed to the case of the evil spirit of the desert

Rena is the person sent by the first uncle to spy on Uncle Man, and if Rena dies, the first uncle will definitely start to be suspicious. Indeed, later the Youth Federation sent Tang Yingxuan to the desert to look for clues. After I entered the border province, I gradually began to suspect Uncle Man, and after discovering Rena's head, I began to doubt Uncle Man.

It's just that Uncle Man is not an ordinary person, he did not fall into the conspiracy of the people behind the scenes, but made me gradually believe that he is definitely not the person behind the scenes.

Shen Cheng gave an explanation, but he had no way to explain the second question.

After thinking about it for a long time, I suddenly spoke slowly.

I thought of a possibility: Meng Ting may really fall in love with Du Lei.

Meng Ting, on the one hand, is doing things for the mastermind behind the scenes, but on the other hand, she is really in love with Du Lei. Feelings, have nothing to do with good or evil, Du Lei loves Meng Ting deeply, and it is not impossible for Meng Ting to fall in love with Du Lei. I remembered that when Du Lei kidnapped You Lu to Xiaolinzi, Meng Ting's behavior was very strange.

It doesn't look like it's pretending.

If this speculation is true, many other problems could be solved.

Meng Ting knew all the secrets of Du Lei, and Dr. Liu's hypnosis of Meng Ting failed, but the mastermind behind the scenes was completely as if he didn't know that the mysterious man was Du Lei. There is no routine because Meng Ting did not tell Du Lei's secret to the mastermind behind the scenes.

Because of Meng Ting, I don't want Du Lei to be in danger.

Meng Ting put away You Lu's painting, probably deliberately showing it to me, she was wondering if she was going to give me some hints. Meng Ting doesn't have any feelings for me, but her feelings for Du Lei may be as deep as a crazy demon.

After Shen Cheng heard this, he was stunned, not only him, but also everyone else was stunned by my bold speculation.

I was about to say something more when Shen Cheng stood up. After pacing a few steps in the office, Shen Cheng turned around with a solemn expression, and he looked at me: "If your speculation is true, this may be the biggest opportunity we have ever had. ”

I asked, "What kind of opportunity?" ”

"Lead Meng Ting out, or even, the opportunity to lead the people behind the scenes." Shen Cheng replied.

I was stunned: "Are you going to take advantage of Meng Ting's feelings?" ”
