Lin Pingzhi is not stupid, as soon as he saw that his boss's eyes were wrong, he knew what the problem was, and immediately his face was bitter: "Head, I really don't know who sent it to Qin Qing, I swear, I don't think I leaked the conversation that day!" In fact, when Lin Pingzhi got the package from Qin Qing, he really hesitated for a long time, whether it should be handed over to Liu Yu. Even Lin Ping knew that he thought it was too coincidental, it was as if he was acting, how could there be such a coincidence, Liu Yu on the front foot finally said that he wanted to clean up Gong Liuzhen, and the evidence in his hands was sent by the people on the back foot? He Lin Ping knew that the possibility of being suspicious was too great!

He was uneasy here, but Liu Yu had already withdrawn his gaze. Liu Yu thought about it carefully, with Lin Pingzhi's brain, how could he not do such a traceful thing, and Liu Yu could sense Lin Pingzhi's emotions, and when he replied just now, he did not have emotions such as weakness of heart, so his suspicion was very small.

But Liu Yu couldn't figure it out, when Liu Yu asked Lin Pingzhi about Gong Liuzhen's situation, there were only the two of them in the office at that time, and no one else could hear it. How did the other party know that he was finally going to make a move?

With a flash of his eyes, Liu Yu squinted and began to look at his desk, could it be that someone installed the eavesdropping device? Apart from this reason, Liu Yu really couldn't think of any other reason.

Lin Pingzhi was startled when he saw Liu Yu's movements, and also thought of this possibility, and installed a bugging device in a department of the Public Security Department? This is too serious, isn't it? Although the household registration office generally does not have many opportunities for confidential conversations, the household registration office has the responsibility of guiding the province's household registration business, and it is too bad for a business hub in the province to be monitored.

In order to avoid suspicion, Lin Pingzhi could only stand aside and watch. Don't dare to go over.

Liu Yu carefully under the table and chair. inside the drawer. On the wall behind him, in the books on the table, and other detailed places, I searched one by one, and after searching for about ten minutes, I didn't get any results.

"Director Liu, morning." Tie Dabing and Ma Wangshan stepped on the point to go to work, they met at the staircase, came up together, and shouted when they entered the door. Suddenly, the two found Liu Yu sitting on the sofa and pondering. There was still a bit of a mess near the table, and I was a little confused for a while.

Liu Yu reacted, nodded his head slightly, fell into deep thought, gently rubbed his chin, and carefully observed his desk.

There are generally two kinds of common eavesdropping, one is wired eavesdropping, that is, through telephone lines, communication cables, network cables and other preset special eavesdropping lines, which can monitor the content of the telephone in real time, which is the most widely used means of eavesdropping. But. It is unrealistic to conduct wired eavesdropping in the public security department, and the telephone lines of important government departments have been encrypted. There will also be regular inspections, and there is a technical department within the public security system, and if you want to engage in wired eavesdropping in a place like the Public Security Department, it is no less difficult than playing stealth under a thousand pairs of eyes.

So, wired eavesdropping is unlikely, it may be wireless eavesdropping! Wireless eavesdropping is a means of using small eavesdropping equipment to secretly place in certain places and obtain information remotely by using small eavesdropping equipment. The scope of eavesdropping is very narrow, and the diameter of civil eavesdroppers is generally not more than three meters, and if this diameter is exceeded, the frequency of the received signal will be disturbed, and the radio receiver in the hands of the eavesdropper cannot receive radio waves normally.

Therefore, if it is wireless eavesdropping, then the eavesdropping device must be installed near Liu Yu's desk, and his desk is within three meters in diameter, and only his desk is there. As for special eavesdropping methods, such as radiation eavesdropping and mobile phone eavesdropping, these basically belong to special military fields and are impossible for ordinary people to access.

But where is the bugging device? Liu Yu searched carefully and failed to find the location of the eavesdropper.

Ma Wangshan pretended to be casual, and when he passed by Lin Pingzhi, he gently stabbed Lin Pingzhi in the back with his elbow, and Lin Pingzhi understood and quietly followed Ma Wangshan.

When the two arrived at the pantry on the side, Ma Wangshan said curiously: "Director Liu, what is this?" ”

Lin Pingzhi's face was full of solemnity, and he said in a low voice: "Something happened, Director Liu suspects that there is a bug on his desk!" ”

"What? Really? Ma Wangshan smacked his tongue, he had handled many official corruption cases, and the method of eavesdropping was not new to him, not only had he seen officials eavesdropping on each other, but he himself had also used eavesdropping. Just dare to put a bugging device in front of Liu Yu's desk, Ma Wangshan is covered in sweat and hair and stands upside down, is there really someone who is not afraid of death, dare to eavesdrop on Liu Yu?

At this time, Tie Dabing also walked over suspiciously, inquired about it, and learned that it was a bugging device, and his face immediately changed. If you want to talk about the household registration office team, who is the most idle, there is only the iron soldier, and there is basically no national security in all the work in peacetime, because there has been no special incident that needs to use national security so far. Listening to the eavesdropper at this moment, the Iron Soldier can be regarded as finding the right business.

"I'll take a look." Tie Dabing couldn't say anything, stepped up to Liu Yu, and said with a meticulous face: "Director Liu, I can help you." ”

Liu Yu was still scratching his head and missing what doubts he missed, he was stunned when he heard the words, and then he was slightly happy, isn't this a person with national security? They eat this line of work, looking for bugs is not pediatric? Get out of the way and make room for the Iron Soldiers.

Tie Dabing's face was calm, he squatted down, a pair of resolute eyes were particularly sharp at the moment, slowly swept the suspicious corners of the desk, and from time to time he would reach out to touch it, looking for about five minutes, but he didn't find any results. But unlike Liu Yu, the details that Tie Dabing paid attention to were not comparable to Liu Yu at all.

He found an iron ruler and kept groping in the cracks of the desk, the computer case, and even the keyboard, looking for foreign objects. After searching for five minutes, he still didn't get any results, but it didn't disrupt the rhythm of the Iron Soldier in the slightest, and he began to search for the items on the desktop, books, books, and folders were the things that must be checked.

However, after searching for five or six minutes, no suspicious items were found, and at this time, everything on the table was almost detected, and if there was a bugging device, it should have been found. Liu Yu began to doubt his judgment a little, was it really a coincidence this time?

But the Iron Soldier didn't give up at all, just stopped in place, thought for a while, and glanced at the items on the table. Suddenly, Tie Dabing's gaze was the most distracted, and he stayed on a plastic pen holder on Liu Yu's desk, with a hint of suspicion.

Liu Yu looked over, the plastic pen holder itself is fine, just now Liu Yu also poured out the stationery inside to check, the bottom is empty, plus the pen holder is very thin, there should be no problem.

The Iron Soldier's gaze was not at the pen holder, but at one of the black pens! Intuition told Tie Dabing that there was something wrong with this pen, so he took it out and spread it in the palm of his hand and said, "Director Liu, this pen is yours?" ”

Liu Yu looked at it fixedly, and was also a little puzzled, there were a lot of pens in the pen holder, and they were all prepared by Lin Pingzhi, when did the extra pen, he really didn't care, so he shook his head slightly.

Tie Dabing opened the pen with a solemn expression, and when he opened the pen cover, there was no abnormality inside, but when he unscrewed the end of the pen, an amazing picture appeared! The tail of what should have been an ink gall was empty, replaced by a small chip-like element with a diameter of two centimeters, and a red miniature signal lamp glowed red from time to time, transmitting radio signals.

"That's it!" Tie Bing breathed a sigh of relief: "The production is rough and not precise enough, it should be a civilian bugging." ”

Finally figured it out!

Moreover, someone is really listening to Liu Yu!

"Can you use this to find out who is listening?" Liu Yu's eyes were filled with a cold light, he didn't mind that someone was making small moves behind his back and using him to clean up some people, as long as those people really should clean up, he didn't mind. can install a bugging device in front of him, which is not something Liu Yu can tolerate! To put it mildly, the eavesdroppers used Liu Yu as a doll, slapped him severely, and trampled on his dignity. Gong Liuzhen, Liu Yu will still clean up, but this eavesdropper, Liu Yu didn't plan to let go!

However, when Tie Dabing heard this, he shook his head slightly: "I'm afraid it's difficult, the other party's signal receiver can be accepted within 8 kilometers, and it is difficult to find the other party's receiver, if the other party's receiver is still on, there may be a little hope, but if it is turned off, then there is really no way." ”

When Liu Yu heard this, his brows furrowed into a pimple, and he said coldly: "Hmph, I don't believe I can't find you!" Just send a package to my people, just secretly instruct Fang Tian and his wife to stop the car, give me a bug, no one can save you! ”

"Pingzhi, you can take this phone number and contact them!" Liu Yu gave Lin Pingzhi the contact information left by Fang Tian and his wife, and asked him to come forward to ask the person who was guiding them behind them, if Fang Tian and his wife still wanted Liu Yu to help them solve the case, they should know what to do.

Lin Pingzhi immediately went to do it, and Liu Yu began to accept the package sent by this person.

Thinking about it now, Liu Yu found that this person was quite scheming, mailed the package twice in the early stage, repeatedly tested Liu Yu's meaning, and never refused to hand over the evidence that he had already mastered, until he was sure that Liu Yu was going to do it, so he sent the evidence.
