Xu Yanfeng did not go home to rest, but returned to his office.

Because Xu Yanfeng knew that Gao Lei would definitely find a way to contact him, and Gao Lei had been a jǐng cha for so many years, he must also know how jǐng cha worked.

At present, the Public Security Bureau will definitely monitor Xu Yanfeng and listen to Xu Yanfeng's mobile phone.

However, due to the special xìng of the office phone, the public security bureau cannot listen to the office phone at will without sufficient evidence and instructions from the leadership.

Therefore, Xu Yanfeng guessed that if Gao Lei wanted to contact him, he would definitely call the landline in his office.

So, after Xu Yanfeng returned to the office, he sat down all morning.

Although the phone on the table rang several times during this period, it was not Gao Lei who called.

At about half past three in the afternoon, the phone rang again.

"Hey!" Xu Yanfeng picked it up and said.

"Yanfeng, it's me." Gao Lei's voice came from the opposite side.

"I've been waiting for your call, what the hell is going on?" Xu Yanfeng said in a low voice.

"I don't know." Gao Lei's voice was very anxious: "After we broke up last night, I took a taxi home." But someone on the road stopped our white spoon taxi, saying that there was an emergency to report to me and let me get off first. I didn't think much about it, so I followed the other party to a corner, but I was suddenly stunned by rushing out of nowhere. When I was woken up by your call, I found myself in a disused warehouse on the outskirts of the city. You should have heard everything from the phone. Fortunately, I took advantage of Feng Haiqiang's slack on the phone with you and ran out. If they take it back, I can't tell if I have a hundred mouths. ”

Speaking of this, Gao Lei asked again: "Does Ma Juan know about me?" How is she now? ”

"She got it. Jǐngcha brought her back to make a transcript, and I guess she's grieving about your business right now. Xu Yanfeng said.

"Scold, which grandson hurt me so much." Gao Lei scolded.

"I think it has something to do with the gunman you saw." Xu Yanfeng said.

"That's what I thought, too. Damn, the gun they stuffed into my waist was the one I saw that night, exactly the same model. And the dead man was the one they took away that night. Gao Lei said.

Xu Yanfeng said: "I will help you find out about this matter." The most important thing for you at the moment is to hide well and not be discovered by the police. If they are really discovered, they really can't escape, and they would rather be caught than exchange fire with them. They're probably trying to shoot you, and if there's an exchange of fire, they'll have a reason to shoot you. ”

"I understand." Gao Lei said: "How do you want to check this matter?" ”

"Let's start with Maoxing Construction Company. Since that Fan Yaowei is with the other party, there must be a problem. followed by Han Kefeng, I think Feng Haiqiang must have participated in framing you. And that Feng Haiqiang, it is estimated that Han Kefeng entered. Xu Yanfeng said.

"I don't know about this, and I'm not familiar with the criminal investigators, but I should be close to ten." Gao Lei said.

"So, we have to do it in two ways. Han Kefeng's side could only ask Director Xiao to help. ”

"Good. If you need me to do anything, you contact me. I have a new mobile phone card, I don't need identity information, the number is 131********. After Gao Lei finished speaking, he was silent for a second and said, "Help me tell Ma Juan that I'm fine, let her not worry." If I can get past this, we'll get married; If she can't get by, let her forget about me and find a new man. ”

"You, you're going to get through this. Do you look down on me when you say such frustrating things to me? I don't think I can help you. Xu Yanfeng scolded.

Gao Lei smiled bitterly: "I didn't mean that, okay, let's do it first." ”

Hanging up Gao Lei's phone, Xu Yanfeng called two people from the office and went straight to Maoxing Construction Company.

Xu Yanfeng wanted to find a job to spy on Fan Yaowei.

However, I didn't expect Xu Yanfeng to go to Maoxing Construction Company and ask to see Fan Yaowei, but the other party said that Fan Yaowei went to Nancang and could talk to the deputy manager of the finance department about anything.

I simply made up some work things and talked to the assistant manager of the other party. Of course, while talking, I didn't forget to spy on each other.

However, the results of the snooping made Xu Yanfeng very disappointed, and he did not find any useful information.

Obviously, even if Fan Yaowei was involved in the gunman's Jihua, it did not mean that all of Maoxing Construction Company's employees were involved.

It is also a pure waste of time to contact and snoop on these people who do not understand the situation.

Walking out of the office building of Maoxing Construction Company, Xu Yanfeng was thinking about what Fan Yaowei was going to Nancangqian, and suddenly a comrade from an office who came with him said: "Isn't that their Manager Fan's car, just parked downstairs, how can you say that you are not in it?" ”

The deputy manager who sent him off hurriedly smiled and said, "Our manager went to another car, his car broke down and was about to be repaired." ”

Xu Yanfeng smiled, shook hands with the other party and said, "We don't have anything to do, we have made it clear to you, and we will go back." ”

The other party hurriedly smiled and said, "Okay, good, Director Xu is welcome to come and check our white spoon work at any time." ”

The two hands were separated, and Xu Yanfeng sat in the car.

Although it was only a brief handshake just now, Xu Yanfeng spied on the other party's heartbeat, and said secretly: "Fortunately, I reacted quickly." But I didn't know that Manager Weishenme Fan didn't see them. ”

With this message, it is more certain that this assistant manager does not know anything; But he is also more certain that Fan Yaowei must have participated in framing Gao Lei, and knew that Gao Lei and Xu Yanfeng had a good relationship, so he didn't even see Xu Yanfeng. lest he say something wrong and make Xu Yanfeng suspicious.

Through the formaldehyde case, Xu Yanfeng knew that Maoxing Construction Company was very cautious, and it could be said that it was leaky.

Walking back from Maoxing Construction Company, Xu Yanfeng has been thinking about how to start investigating this matter.

Since Fan Yaowei didn't see Xu Yanfeng, he couldn't help but snoop if he wanted to. And even if Fan Yaowei saw Xu Yanfeng, he might not be able to spy on any useful information.

If Fan Yaowei's phone calls can be monitored, it will be more comprehensive than the information obtained by spying on his mental activities.

Because snooping can only spy on a very short period of mental activity, it is impossible for Xu Yanfeng to stay with Fan Yaowei for a long time to spy on him. But to listen to the phone, that can be monitored for a long time.

If you can't listen to useful information, you can continue to listen to it. This gives you more access to hidden information.

But how to listen to it?

Listening devices are only available to the public security department. Now there is no evidence of Fan Yaowei's violation of the law, if the public security department is allowed to listen to the house, then it is strange that the house can be agreed.

Just thinking wildly, Cao Bingliang called Xu Yanfeng.

The phone was connected, and Cao Bingliang opened his mouth and asked, "Director Xu, did Gao Lei have an accident?" ”

Obviously, Cao Bingliang has learned about what happened to Gao Lei through some means.

"Well, I'm a little busy right now, I'll call you later." Xu Yanfeng said.

Now there are two comrades from the headquarters office in the car, and Xu Yanfeng is still talking to each other on his mobile phone, so it is inconvenient to say some things.

Back in his office, Xu Yanfeng called Cao Bingliang.

"It's inconvenient to talk just now, and my phone is likely to be monitored." After Xu Yanfeng finished speaking, he said: "Do you know about Gao Lei?" ”

"Yes, I just heard that. What the hell is going on? How could Gao Lei possibly enter? Cao Bingliang said hurriedly.

Xu Yanfeng sighed lightly, and then told Cao Bingliang about his guess and the direction of the investigation.

"The only clue now is that Fan Yaowei, and the only way to find the one who is holding a jǐng with a pistol can only be found through Fan Yaowei. But now there is no evidence, and we must not be expected to help the police investigate Fan Yaowei, so we can only do it ourselves. Xu Yanfeng said: "I want to listen to Fan Yaowei's mobile phone, do you have a way?" ”

"There is a way. The common method is to monitor through the telecommunications department, and I estimate that if the public security wants to monitor your mobile phone, it must be the telecommunications department that will pass through. But if we want to spy on Fan Yaowei's mobile phone, we must not go through the telecommunications department. Because we don't have paperwork, the telecom department can't let us listen to a private phone at will. So, only through some special devices. Cao Bingliang thought for a while and said, "I can get one, but this device needs to be installed in the other party's mobile phone." The installation process is very simple, but how to get the other person's phone is a problem. Moreover, the signal emitted by this device can only cover 100 meters, which means that we have to listen within 100 meters. Beyond that, then it is not audible. ”

Xu Yanfeng thought for a while and said, "When I came out of Maoxing Company today, I seemed to hear that they were recruiting sanitary workers to clean the corridors. We can find an applicant to apply to Maoxing Construction Company and let him listen to it. ”

"It's a way. However, this entry must be familiar with the equipment, have a good psychological quality, and be tenacious and able to endure hardships. Because it can be a long-lasting job. Therefore, it is better to be a soldier or a thousand people in the public security system, and you must be a freshman......"

With Cao Bingliang's narration, Xu Yanfeng also thought of an entry. Qiu Mei's husband Li Tiehai.

Li Tiehai is honest and shy, and Xu Yanfeng can be regarded as a great favor for him. If you explain the matter to him clearly and ask him to help monitor Fan Yaowei, presumably Li Tiehai will not refuse.

Moreover, Li Tiehai was born in the army, and I remember Qiu Mei saying that he was engaged in communication jishu in the army, so he should not be unfamiliar with listening equipment. And not long after he came back, although he had already worked in the Yuanxi County Finance Bureau, because he often didn't go out before, he could be regarded as a face that could not be regenerated.

If Li Tiehai is asked to take a period of leave to help with this, then he should not refuse, and he will be very good.

Thinking of Li Tiehai, Xu Yanfeng also thought of how to install the monitoring device into Fan Yaowei's mobile phone.

After talking to Cao Bingliang about Jihua, Cao Bingliang said, "Okay, just do it." Let's go to Maoxing Construction Company to apply for a job first, and I'll give you the equipment in these two years. ”
