I don't want to solve the case when I'm a little policeman.

The highest level of plastic surgery is to look the same as if you haven't had plastic surgery, but you have become another person, even crossing the gender. To put it a bit exaggerated, that is "head replacement surgery"!
As for the emotional changes such as demeanor, movements, and eyes after plastic surgery, after undergoing rigorous training, it is like rebirth of another person.

This 16-year-old girl looks exactly the same as her ID card, there is no difference at all, but her 3D computer modeling, the shape of her head is slightly different, even if a normal person sleeps flat when she was a child, the whole head will have a natural curvature , but her head seemed to be pieced together.

Just like choosing one of three watermelons to form a new melon, no matter how perfect the new melon looks, it will feel weird in front of a master portraitist and skull restorer like Xu Zheng .

The security check was still going on, and Xu Zheng didn't have time to think about it. In just 2 minutes, more than 20 people passed through the four passages. While continuing to work, he said to Liu Linlin without turning his head: "Hurry up and inform Team Yang, I personally think , that girl just now is [-]% the target you are looking for."

There is no reason, the operation performed by a master-level plastic surgeon is the biggest reason.

The work continued, not to mention that there were nearly a thousand people on this train, and there were more than a dozen people who underwent plastic surgery, including three men. After Xu Zheng finished marking, he immediately asked Liu Linlin to report it.

The high-intensity work lasted for 8 minutes. Finally, the passengers of the G1812 train passed the security check. As for the people who were stranded on the platform and did not leave the station, the Yang detachment had already sent people to investigate.

Xu Zheng went back and looked at the 20D modeling of more than 3 passengers that he missed just now. After finishing these tasks, he heaved a sigh of relief. Humans are still not as good as computers. He persisted for more than ten minutes, and he couldn't do it. up.

Fortunately, the rest of the work has nothing to do with him. Logically speaking, he should withdraw from the operation at this time, but because the whole operation is integrated, all those involved in the operation cannot get out without formally arresting the two target persons. red bridge.

Xu Zheng wanted to find a place to rest, but he was called to the conference hall by Team Yang.

As soon as he entered the conference hall, he was attracted by the huge display screen on the wall. At this time, the giant screen was divided into hundreds of small screens. The conference hall was filled with 70 to [-] people, who were in charge of monitoring these people on the screen.

Without thinking too much, he guessed that these people should be the G1812 train stranded on the Hongqiao high-speed railway. At this time, all passengers who did not leave the station automatically became the surveillance targets of the police.

Xu Zheng had excellent eyesight, and after scanning twice, he found the screen monitoring the female students.

At this time, the female student was standing by the window of platform B1, wearing headphones as if she was watching anime, chewing on something, and the cameras around her switched angles in turn, but none of them captured what was on her phone.

The Shanghai police also used a high-altitude simulated drone for high-definition shooting. Unfortunately, only the face of the female student can be photographed, and the contents of her mobile phone cannot be photographed.

As for the mini simulation camera, it was also monitored not far from the head of the female student, but no useful information was obtained either.

Seeing Xu Zheng coming in, Detachment Yang beckoned. He was a serious person at first, but he hadn't formally identified the target person yet, and there was no smile on his face, "Xiao Xu, come quickly, look at this woman's mouth. What are you talking about?"

It turned out that he was asking himself to translate lip language. Xu Zheng felt a little helpless. It was really not easy to get a set of mini simulation cameras in his hands.

When he approached, Yang Detachment and the others stepped aside, and a computer desktop showed a picture of a female student chewing with her head down, as if she was talking to herself, but everyone present in the conference hall did not dare to be careless, worried that the female student would There is a meaning to every student’s actions.

Xu Zheng observed for a while, then shook his head, "Leaders, if I can't do anything, her lips move, but there is no rhythm, and there is no way to translate it. Anyway, in the voice I know, it doesn't match her."

Team Yang had considered this before, and was not disappointed when he heard this. He asked Xu Zheng to look at other suspicious targets and help them conduct a second screening.

In just this moment, four or fifty people left the original hundreds of suspicious targets, and now there are six or seventy people at the high-speed rail station, and more than 50 of them are going to Hongqiao Airport. Team Yang asked Xu Zheng to help focus on these 70 people. many people.

In fact, the information of these 20 people has already been investigated by the police in Shanghai, including the air tickets they ordered, especially the international flights purchased by more than a dozen of them, which is the focus of their investigation.

It's just that Xu Zheng observed the cameras monitoring them for a while, and found nothing suspicious, because these people basically didn't deliberately avoid the cameras, and their words and deeds were the reactions of ordinary people, including lip translation for them. It is the short story of the parents and the expectation of a foreign country.

This is simply ineffective monitoring and a waste of the energy of the investigators.

Xu Zheng felt that Team Yang's arrangement was not very good, but he couldn't think of a better way, and now the stupid way has the advantage of being stupid, that is, whoever these people meet will be caught by the camera.

Even the restrooms in Hongqiao have monitoring equipment, which can be said to monitor the entire Hongqiao building at 360 degrees without dead ends.

The plane from Australia has already landed at Hongqiao Airport, and now the passengers are taking their luggage to prepare for the station. Unlike the high-speed rail, only Hongqiao’s own security check at the exit of the airport will be tested, and the police are not involved. Xu Zheng is curious. But I didn't ask, probably because there are too many foreigners, and the leaders above did not approve the 3D scanning of them.

Soon, the passengers of this plane walked out of the exit of Hongqiao Airport, and another target person that the Yang team was looking for was also among this group of people. It would take more than ten hours for these passengers to fly from Australia to Hongqiao.

At this time, everyone seemed very tired, and basically left Hongqiao Airport directly from the exit.

Of course, a few people took a short break and rushed to the Hongqiao high-speed rail station. It seemed that they were going to take the high-speed rail to their next destination.

In view of this situation, the Yang detachment arranged multiple plans. In addition to thousands of cameras to track and monitor these people who stayed at Hongqiao Airport and the high-speed rail station, he also sent two teams of plainclothes policemen to track them.

But unfortunately, after 10 minutes, these people who stayed behind did not meet and communicate, as if they were really passers-by, and they didn't even meet each other.

"Liu Ju, can you ask if there is any abnormality in the technical team?" Team Yang and Xu Peixin looked at each other in blank dismay. Could it be that the news they got was false?
Bureau Liu hurried over to inquire, but unfortunately, the various anti-reconnaissance electronic instruments arranged by the public security sub-bureau in front of their station found nothing suspicious.

Just when everyone was overwhelmed and at a loss, Xu Zheng, who had been lying in front of the computer, suddenly said to Detachment Yang: "Detachment Yang, this female student is probably the target person you are looking for.

And the target person you are looking for to get off the plane is in the smoking room of E6. You see, it is the middle-aged man standing by the window. "

After several leaders heard the words, they hurriedly walked to Xu Zheng's computer, and Xu Peixin asked anxiously, "Xiao Xu, don't scribble, tell me your reason."

Xu Zheng switched the surveillance video to the drone camera. In the high-definition video, the female student is still chewing something in her mouth. This is normal. Some people can chew betel nuts for a day.

But compared to half an hour, her expression has changed a lot
The Yang detachment is in charge of today's arrest operation, but now seeing that the best time for arrest is about to pass, their mission is about to fail, and Xu Zheng is still here to explain the reason slowly, he is a little anxious, "Xiao Xu, you need the details Afterwards, you just talk about how they communicated."

You must know that all the information exchanged by electronic devices in the entire Red Bridge will be detected, and the female student has been watching the video, and her mobile phone has not transmitted any information at all.

"They communicate with each other using high-frequency microwave pulses."

The person who spoke was Hong Chenchen. Seeing that the police hadn't acted for a long time, he must have not identified the suspect, so he brought Qu Ying over, just in time to hear Xu Zheng's analysis just now.

This gave him a wake-up call, and he immediately thought of this microwave pulse transmitting instrument that can communicate over short distances without any electronic components.

Microwave pulse, several leaders present are people of certain status, well-informed, have heard of this short-distance communication method, but have not seen it, mainly because this communication method can only be used within a range of 500 meters Inside.

The middle cannot be blocked by something particularly thick, otherwise the microwave pulse cannot penetrate.

The most unpredictable thing about this method is that its operation does not rely on electricity, that is to say, there are no electronic components, no batteries, and no electronic transmitters in this instrument.
Without these things, the anti-information reconnaissance equipment installed by the Hongqiao branch in this building would be useless.

Seeing that some people didn't believe it, Qu Ying took out her mobile phone and found a group of photos, "Look, this is our unit's high-frequency microwave pulse transmitter, a very small thing, similar to a power bank.

There are two patches, one placed in the ear and one placed in the throat, and the user vibrates the throat to reflect the audio, and waits until the second user receives the microwave pulse.

This power bank big thing is translated and transmitted into his ears.

But what they transmit is not the voice of speech, but audio, and the audio received by the recipient has to be translated into speech himself.

In layman's terms, you can be regarded as two people communicating with Morse code 500 meters apart, but it is not electronic information exchange, but audio. "

After saying this, everyone understood. Team Yang and Xu Peixin looked at each other, and they both understood what the other party meant, that is, whether it is right or wrong, "catch" first.

As soon as Detachment Yang gave an order, the plainclothes police officers on the ground rushed towards these two people. The whole process went smoothly. The female student and the middle-aged man did not resist at all. When they were arrested, they looked astonished, as if they didn't know why the police arrested them. of.

Xu Zheng was relieved to see the plainclothes police quickly evacuate the scene after catching these two people.

At this moment, Director Liu suddenly remembered something, and asked in a low voice, "Is this microwave pulse the monitor used by the Soviet Union to the beautiful country's embassy in the Soviet Union?"

Xu Zheng smiled and said: "Yes, that's the thing, but now the technology is much more advanced than that time, I remember this thing was invented in 1945, what is it called golden lips, the people of Su at that time were really smart.

Literally monitored the beautiful country for eight years. "

Hong Chenchen added: "Su Guo overheard a piece of news back then, but unfortunately we didn't pay attention to it, it's a pity"

"Cough cough."

Before Hong Chenchen could go any further, several leaders next to him covered their mouths and coughed at the same time, good guy, young people nowadays really dare to say anything.

Liu Ju took a careful look at Xu Zheng, feeling so ashamed, this young man is worthy of being valued by the leaders of the ministries and committees, his reaction is too fast, and his knowledge is so wide that ordinary people can't even think of it.

Hong Chenchen came over and patted Xu Zheng on the shoulder, and scolded with a smile: "You kid has come to the Devil's City several times, and you didn't talk about getting together with us, why, you don't want to see us?"

Xu Zheng responded with a smile, "No way, I don't want to look for you, but I'm here for business, or I was arrested as a young man, or you can ask Mr. Xu, I don't have any free time at all."

Xu Peixin couldn't care less about them reminiscing about the past at this time, "Don't talk for now, let's go, let's go and see if the two people we just arrested have the kind of equipment you mentioned."

Everyone rushed to the Hongqiao branch. Now the female students and middle-aged men were locked in the interrogation room and searched. As for the reason the police used, it was nothing more than that they were reported by someone.

When Xu Zheng and the others arrived, the technical police of the Hongqiao branch were dismantling two charging treasures, which were connected to something like an earphone.

Seeing a group of leaders approaching, the person in charge of the technical police quickly stood up and reported, "Leaders, this thing they have is not a power bank, it should be a short-distance audio transmitter.

But there should be special secrets for receiving and transmitting messages, and ordinary people cannot use such things without training or without their passwords. "

Detachment Yang finally showed a relieved expression on his face when he heard the words. It doesn't matter now, as long as he can be sure that the person is not wrong, he looked at Xu Zheng and said gratefully: "Thanks to Xiao Xu this time, otherwise, let this The two finished the conversation right under our noses.

It will be more difficult to catch them later. "

Xu Zheng thought that these two people would definitely meet to do some kind of transaction, but he didn't expect that they just exchanged, probably to discuss changing the trading location. In fact, he was also a little afraid, if he didn't have the audio recognition technology given by the system, I really don't know about microwave pulses.

Without knowing the microwave pulse, today's mission will definitely fail.

If it fails, he is not only ashamed to use the simulated camera, but also embarrassed to ask for a computer 3D scanning device.

Fortunately, the result is good now. Since Team Yang has determined that the target people they want to catch are female students and middle-aged people, it means that Xu Zheng's mission is over.

As for the subsequent interrogation and other work, these are the affairs of the Shanghai police.

So, he accepted it as soon as he saw it, and immediately offered to leave. Team Yang and Mr. Xu didn't stop him this time, and sent Liu Linlin to assist him in his work.

Before leaving, he apologized to Hong Chenchen and Qu Ying: "Director Hong, Sister Yingying, let's do this for today. We will make an appointment after I finish my work."
