Just when Luo Chuan was a little distracted, the mobile phone suddenly rang. There was no way, Luo Chuan came back to his senses and had to pause the radio broadcast first.

When I picked up the phone, I heard a frantic roar from Luo Chuan's boss, Director Yang, on the other end of the phone: "Luo Chuan! What the hell are you doing now! Just now, two or three minutes ago, all the police cars outside in several districts sounded a moonlight sonata! Is this going to be a piano concert for our city!? Dozens of police cars sounded the moonlight song at the same time, and they couldn't be turned off! Do you know how bad that effect is! Come on, come on, tell me, do you don't want to do it anymore, or do you don't want wo to do it?! What are you still doing out there? Hurry up and get me back to deal with this! Beethoven and I both need a reasonable explanation! ”

Before Luo Chuan could ask more carefully, the director hung up the phone angrily.

Guan Shan looked at Luo Chuan's complicated expression, and asked with some concern: "What's the matter, is things worse than we expected now?" ”

Luo Chuan exhaled heavily and replied, "Just now, we held a police car concert for that demon. On our side is the main switch, and at the same time, dozens of police cars sounded a moonlight sonata. Hell, we listened to the whole song with great interest. If we don't stop, they won't turn it off. It's hard for me to imagine how ridiculous and funny the picture just now is...... This kind of high-tech means is not something that ordinary people can do. ”

"No one ever said he was an ordinary person. Go, and I'll go back to my place, with this device. Just after you pressed pause, I heard something behind me, but in order to avoid giving the amplifier to all the police cars, let's take it and listen to it alone. Guan Shan asked Luo Chuan's opinion with his eyes.

Of course Luo Chuan agreed, when he didn't understand the ins and outs of this matter, he didn't want to make a storm in the city and people panic.

So, Luo Chuan followed Guan Shan to Guan Shan's home. After carefully studying it and making sure that it would not trigger the "concert" effect again, Guan Shan replayed the contents of the USB flash drive.

After the melodious "Moonlight" was played, about another minute and thirty seconds later, an elegant male voice suddenly came from the stereo. The voice was slow and cold, as if every word was a voice from the depths of hell.

"Luo Chuan, if you have enough composure and patience, then you will be the only one among all the police who has heard my real voice. For the past year, I have enjoyed this song "Moonlight", which inspired Beethoven in the midst of excruciating suffering. So you see, suffering and destruction are not terrible, it is perfectly capable of creating something better. Without painful illness and psychological torture, there would be no Beethoven and no Moonlight. Without me, this city would not have a place for you, the heroes of justice. People only need heroes and justice in times of danger and fear, and in times of peace and prosperity, who will remember who is a hero? I think I should help you selfish and ugly people remember the heroes of a year ago. The city needs a higher level of crime, and if you seek pleasure from slaughter, what is the difference between that and a lowly murderer? I heard that you have a very good psychologist by your side. It just so happens that the sick murderers in this city are going crazy to commit crimes. Let me see if you and your people are qualified to be the next hero of this city. ”

This elegant and cold male voice is calm and calm with arrogance and contempt. He seems to be looking at everything from above. When he said all the parts, the USB flash drive also stopped abruptly. If Luo Chuan and Guan Shan didn't wait patiently for that minute and thirty seconds, they would have completely missed this demon's provocation and the message he gave.

The two of them were silent for a moment, and then Luo Chuan smiled a little bitterly: "I really didn't expect that from a change, the word hero came out of Tai's mouth, it was so natural." He is revealing his identity to us and declaring war on us. He said that he wanted to remind us of the heroes of the past, was it the S who fought him to the death? Is the person who was responsible for solving this case still alive......" Luo Chuan was a little dazed, because in the police circle, everyone knew that the genius who solved the case had evaporated from the world, and he was like dead, and there was no news of this person, and the police file completely erased this person. In this world, there seems to be no such person.

Guan Shan thought for a moment and said: "Judging from this audio, the person who solved the case should still be alive." And this demon also knows that he is still alive, as for where this person is, I think we can only find out by exploring slowly. I want to tell you, Luo Chuan, this devil is no longer a simple criminal, you must not despise him. ”

Luo Chuan nodded seriously: "I know." You must have heard something from him, right? Talk to me. ”

Guan Shan stood up, poured a cup of tea for Luo Chuan, took a sip himself, walked to the window and said slowly: "Do you know Maslow's demand theory?" He hierarchies human needs into five levels. The most basic and low-level needs are physiological needs. It refers to the most basic needs of life, such as food, water, and air, which are all indispensable. Neither of us can survive without any conditions. In this case, the people at the bottom of the need only have enough food and clothing, sunshine and air in their minds, and they have no intention of thinking about anything else. The second level is security requirements. On the premise of being alive, people began to think about how they could make themselves feel more secure. This includes how to ensure the safety of one's own life and property, and how to ensure good health. Let's put it this way, people with a layer of needs, because they want to live, they will eat anything when they are hungry. But when it comes to the person on the second floor, if you grab a handful of soil and give him a handful of soil, he won't eat it, because it is unhygienic and unsafe. When it comes to the third level of need, it is emotional need, when a person can ensure that he is safe and alive, he will want a warm emotional and physical reproduction need. Not only lovers, but also worship and religion. Those who are not satisfied with food and clothing do not have the heart to talk about faith. This is followed by the fourth need, respect and affirmation. When this demand can be reached, it is generally more successful among normal people. They need to be recognized for their achievements, their high social status, and the respect and affirmation of the public, so as to highlight the meaning and value of their existence. As for the last highest level, it is self-realization and self-transcendence. The reason why it is said to be the highest level is because it is generally difficult to attain. The higher the level of need, the fewer people are needed. If this is compared to a pyramid, then the person who reaches the highest demand is the person who stands at the top of the pyramid. He may have fulfilled all the ideals and needs of life, he realized himself, he had everything. When there is no goal to climb upward, the only thing that can be done is to surpass yourself. Luo Chuan, can you understand what I mean by applying this level of demand to crime? ”

After listening to Guan Shan's professional and straightforward explanation, Luo Chuan nodded thoughtfully and said: "I understand that the lowest level of murderers is the kind of ordinary criminals who are impulsive or impulsive for money, and the purpose of their crimes is to meet the most basic needs. And then as the need increases, so does the psychological change of the offender. When the pleasure of a murderer is no longer just killing, then this person should be on a higher level of demand. So, that demon he ......"

There was no doubt that he was already at the top of the pyramid. If a year ago, his contest with the myth of the police world was his self-realization, then what he has to do now is self-transcendence! He no longer likes low-end bloody killings, he wants something higher. That's why he would say that the city needs a higher level of crime. Guan Shan said with great certainty.

Luo Chuan frowned and said: "As far as I know, he was almost arrested a year ago, but because he changed his appearance, he finally escaped from under the nose of the police, thus realizing his need to defy the police." After that, he finds out some people whose crimes are unforgivable, but who will not be sentenced to death, brutally kills, confuses black and white and becomes a judge, thus fulfilling his chaotic need for innocence. So now, what does he want? ”

"Sooner or later, we'll understand. Now that he has appeared, and he has revealed his identity in such a grand manner, it shows that what he wants to do has already begun. The reason why he made such a big move to make all the police cars sound moonlight was probably to use his unique humiliating way to remind the police that the case was not over and that he was not dead. Perhaps, it is also to convey a message to the disappeared S. Guan Shan also fell into a state of thoughtfulness.

Luo Chuan shook his head, rubbed his temples and said, "Okay, even if we put aside these things we don't understand for the time being." So what does he mean when he mentions you? It seems to me that this is a declaration of war naked, luo, naked! But why would he target you? How does he say that the ability to confirm it is confirmed? No, Guan Shan, you can't enjoy your solitary life here by yourself. I want to explain the situation to the bureau, and I must protect you! I can't let you get involved in this case with me! ”

Guan Shan tilted his head and smiled: "Hey... Luo Chuan, are you scolding me? I've been involved since you called me. Isn't it too late for me to withdraw and hide under the protection of your police? ”

"But ......"

"Don't do it, I'm going back for him. I'm happy to take on his challenge. Don't worry about me, find out if the sick murderer he said is true. I think the challenge he gave me should be related to this person, not something that I brought up to you for no reason. ”

Luo Chuan said a little anxiously: "But now how can we know which of his words is true?" He said that there was a very serious change in mental illness, tai is killing people, and we believed it? So where do we look for it? ”

Guan Shan gently supported his cheeks, rubbed his chin, thought for a moment and said, "Police car, go to the police car to find it." ”

Luo Chuan was stunned, and after reacting, he asked rhetorically: "Guan Shan, when we got out of the car and left, everything was checked, and nothing was found." I asked them to seal the car and keep it intact to carefully check their fingerprints. ”

"Is it as it is?" Guan Shan suddenly looked a little anxious.

Luo Chuan nodded inexplicably and said, "That's right, they won't touch anything." ”

"That's great! Quickly sent someone to watch the car. Even if we checked them all, there was still one thing we didn't check. ”

"Yes...... Sand! Luo Chuan suddenly realized.

"That's right! It's sand! The sand that was sprinkled on the car and painted into musical notes! Why did he use sand? There must be a reason. Guan Shan's eyes had a bright brilliance.

Luo Chuan patted himself and said, "Oh my God, I'm so lucky to have you!" I've been made big by this series of things, and my IQ has plummeted! Let's go, let's go back, and by the way, you and I will go to meet Yang Ju. Hearing his voice just now, I was about to have a cerebral hemorrhage, and I really didn't feel at ease if I didn't go back to see it. ”

Guan Shan smiled and took his coat and went out with Luo Chuan, and when he was on the way, Luo Chuan called to convey his meaning, be sure to collect the sand carefully and give priority to the inspection. Whatever is in there, it must be reported as soon as possible.

The forensic officer on the other end of the phone was very embarrassed and said, "Team Luo...... You can't always jump in line...... There are several more cases in front of you, and the physical evidence of the second team has not yet been fully ......."

Without waiting for the other party to finish speaking, Luo Chuan said domineeringly: "In addition to losing the electric car, he lost his wallet, and no matter how serious it is, the glass of a car was smashed and the things in the car were robbed." Compared with a case where human lives are at stake, can't you tell the difference? Hurry up and mobilize the whole lab and get my sand to the test! If there are not enough people, let Ke Xue test it in person! All in all, the Police Force Evidence Lab is now owned by my sand, and whoever has an opinion has him to contact me directly! ”

Hanging up the phone, Guan Shan on the side couldn't help but smile and said: "This captain of the second team is really unlucky, how did he meet a colleague like you." I said Luo Chuan, how did you get mixed up in the bureau with your way of doing things? I suspect that if I really provoke you, will you not save face, Director? ”

Luo Chuan replied with a cold face: "If you save face for them, then this police force may become a recreation room for retired cadres in the future." I was interested in catching the two thieves, but I was not interested in eating and waiting for death. This second captain has never solved a major case, and his official authority is not small. Not to mention, he can be regarded as a righteous law enforcer who has been diligently catching thieves for the people for ten years. ”

After saying that, Luo Chuan couldn't help but laugh himself.

After returning to the police station, Luo Chuan immediately took Guan Shan to the director's office. He had to explain the matter of Moonlight Qu to the leader, and by the way, he would tell Guan Shan about helping him. After all, it is a bit inappropriate to suddenly bring in a professor from the Criminal Police Academy to help solve the case.
