quadruple sleep

Chen Yezhou's technical analysis results also came out, but after communicating with Lu Nanshen, he found that the information obtained by technical analysis was not as much as artificial. Therefore, when Lu Nanshen and Hang Si came to conflicting results and waited for a third party to corroborate, Found that hope was dashed.

Chen Yezhou had been in contact with Lu Nanshen for a long time, so he naturally knew what he was capable of. He said with some embarrassment that there were interference signals in the audio frequency, resulting in a small amount of information that could be obtained through technical analysis.

Nian Baixiao felt that these words were evasive.

But Lu Nanshen believed what Chen Yezhou said and said, "There are indeed some low-frequency sound waves in the audio frequency, and now I think they are used to interfere with the signal."

From the current surveillance data, no information about the suspect has been found, which shows that the murderer's anti-reconnaissance ability is quite strong. In fact, in this short period of time, no one expected to find anything from the surveillance. If it were so easy to investigate, the murderer would not have the ability to deal with them for two years.

The big information in the audio can be found out, but the result is a headache. According to the information given by Lu Nanshen and Hang Si, it has rained in many places in the surrounding suburbs in the past two days. The approximate area of ​​the woods can be determined by time and direction, but there are many such woods hidden deep in the outer suburbs.

What's more, it may not be in this city. There are many locations in North China that can be found that meet the conditions based on these types of clues. And there may be areas they don't know about?

Nian Baixiao was one head and two older, "I thought you had heard a lot of information and could pinpoint the location."

Everyone thought so at first, except Lu Nanshen.

Lu Nan deeply understands Mr. C’s idea of ​​​​a killing game. How could it be possible for people to easily find all the information based on just one piece of audio content?

Hang Si couldn't help with the matter of restoring the tune. Although Nian Baixiao heard the tune while following Lu Nanshen, he didn't take it seriously. Even if he tried hard to recall, let alone a few syllables, he couldn't even remember a few syllables. I can't even remember the sound.

This requires Lu Nanshen to work independently.

and the need for absolute silence.

The school environment was not good, so Lu Nanshen finally chose Jiang Yu's studio. There were no people coming and going, and the important thing was that the music room was more or less soundproof.

Bai Hao was overjoyed to learn that Lu Nanshen was here, but the keyboardist and flutist were a little trepidatious, obviously afraid of being implicated. But they were afraid. After all, something happened to their good brothers, and they would not stand idly by.

The number of syllables that Bai Hao can recover is limited, and he only relies on memory to recover, so he is not completely sure of the recovered parts.

Lu Nanshen received a call from Mr. C before entering the music room.

Chen Yezhou had contacted Lu Nanshen's mobile phone before. Mr. C took Jiang Yu away and was bound to call Lu Nanshen again, so Chen Yezhou also turned on the tracking mode when the call was connected.

It was still a processed sound, so Lu Nanshen listened slightly.

Mr. C, "What? Haven't you found my location yet? Lu Nanshen, is there something wrong with your memory or your hearing has deteriorated?"

"How did you take Jiang Yu away?" Lu Nanshen was very calm.

Mr. C smiled, "Have you forgotten how your two chiefs died? People who study music are very sensitive to sound waves. This is like a double-edged sword, sensitive to success and failure."

Lu Nanshen's expression was gloomy. He could indeed use his voice to control people.

"Actually, you know very well that it's totally out of the blue for the police to use phone calls to track my location." After speaking, Lu Nanshen heard a set of sound waves here.

He suddenly took the phone away to avoid irritating his eardrums.

Mr. C on the other end is laughing, and the laughter has been processed to be very harsh. "Lu Nanshen, I told you I'm playing a game with you. I'll only give you 24 hours for this round of the game. If you can't find Jiang Yu's location after 24 hours, he will be punished."

24 hour!

Lu Nan raised his wrist and took a deep look.

"Four hours have passed since you discovered that Jiang Yu was missing in the morning." Mr. C sighed again, "You must know that I really hope you can find him, otherwise I will have to kill people, tsk tsk. , it’s not a good feeling to have blood all over your hands. Oh, by the way, you’re familiar with this feeling.” “What do you mean?” Lu Nan asked sensitively.

"Remember, you still have 20 hours." Mr. C reminded him lightly without answering him.

Only 20 hours.

Lu Nanshen wasted no time and locked himself in the music room.

As expected, Chen Yezhou and the others failed to track Mr. C's location, saying that they received strong interference during the tracking process. Hang Si informed, "The murderer came prepared. This is an open provocation."

Because Jiang Yu and Lu Nanshen were involved at the same time, and time was tight, no one in the group had the intention to go to school again.

Bai Hao, the flutist and keyboardist, Nian Baixiao, Fang Sheng, and Hang Si all stayed in the studio, paying attention to Lu Nanshen's situation at all times. They were almost tiptoeing around the studio.

The sound of the piano can be heard from the music room. It is because Lu Nanshen is using musical instruments to restore the tunes he has heard.

not easy.

No one dares to go in and disturb easily.

During this period, the flutist and keyboard player took Bai Hao out to chat quietly. The flutist and keyboard player had little confidence in Lu Nanshen and said to Bai Hao, "The longer it takes to restore the tune, the harder it will be to remember it. How about we Think about it, what else can you do?"

Bai Hao has now become Lu Nanshen's fan. He frowned and said, "Recovery is difficult for us ordinary people, but it is definitely not difficult for Mr. D. Also, what can you two do? Call the police? Didn't watch. Does Officer Chen’s hope also lie with Mr. D?”

The flutist said, "Have you deified him?"

Before they even finished speaking, Nian Baixiao came out and said to them, "Keep your voice down, it will affect the inside."

The flutist and keyboard player were surprised. They came out and lowered the volume. How could they affect the inside? The keyboard player gestured, "How about going outside again?"

Nian Baixiao saw that the position he pointed at was quite far away. He originally wanted to nod, but then he thought about it and decided to forget it and said, "It's best if you shut up."

If he doesn't shut up, he will be punished.

Lu Nanshen didn't even bother to come out just now, so she called him directly and said in a bad tone, "Nian Baixiao, tell the three of them to shut up."

Ok.

The three of them didn't dare to brag after hearing this.

Two hours later, Lu Nanshen came out of the music room.

Everyone stepped forward to meet him.

Lu Nanshen chose a chair and sat down. Hang Si was closest to him. He was surprised when he saw this, "Why are you sweating so much?"

A thin layer of sweat formed on his forehead.

Hang Si stood and Lu Nanshen sat, looking up at her with a pitiful expression, "I'm too tired."
