The highest level of plastic surgery is to look the same as before, but become a different person, even across gender. To put it more exaggeratedly, that is "head replacement surgery"!
As for the changes in demeanor, movements, eyes and other emotions after plastic surgery, after undergoing rigorous training, it is like another person reborn.
This 16-year-old girl looks exactly the same as her ID card. However, her computer 3D modeling shows that the shape of her head is slightly different. Even if a normal person slept flat as a child, the entire head will have a natural curvature. , but her head seemed to be pieced together.
Just like taking 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-level simulation portraitist and skull reconstructionist like Xu Zheng. .
The security check was still going on, and Xu Zheng had no time to think about it. In just two minutes, more than 20 people passed through the four channels. While he continued to work, he said to Liu Linlin without looking back: "Hurry up and inform Detachment Yang that I personally I think that the girl just now is 60% the target you are looking for."
There is no reason, the biggest reason is the surgery performed by a master plastic surgeon.
The work continued, not to mention, there were nearly a thousand people on this train, and there were more than a dozen people undergoing plastic surgery, including three men. After Xu Zheng finished marking, he immediately asked Liu Linlin to report it.
The intense work lasted for eighteen minutes. Finally, the passengers of train G1812 passed the security check. As for those who were stranded on the platform and did not leave the station, Detachment Yang had already sent people to investigate.
Xu Zheng went back and looked at the 3D modeling of the more than twenty passengers he had just missed. After finishing these tasks, he breathed a sigh of relief. After all, humans are still inferior to computers. After persisting for more than ten minutes, he finally No more.
Fortunately, the remaining work has nothing to do with him. Logically speaking, he should withdraw from the operation at this time, but because the entire operation is integrated, no one involved in the operation can leave without formally arresting the two target persons. Red Bridge.
Xu Zheng originally wanted to find a place to rest, but was called to the conference hall by Detachment Yang again.
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 sixty or seventy people, who were responsible for monitoring the 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 target of police surveillance.
Xu Zheng had very good eyesight. After scanning twice, he found the screen monitoring the female students.
At this time, the female student was standing by the window of the B1 platform. She put on her headphones and seemed to be watching anime, chewing something in her mouth. Several cameras around her switched angles in turn, but none of them captured what was on her phone.
The Shanghai police also used high-altitude simulated drones to take high-definition shots. Unfortunately, they could only take pictures of the female student’s face, but not the contents of her mobile phone.
As for the mini simulation camera, it was also monitored not far above the female students' heads, but no useful information was obtained.
Seeing Xu Zheng coming in, Detachment Yang hurriedly waved. He was originally a serious person. The target person has not yet been officially identified, and there was no trace of a smile on his face. "Xiao Xu, come here, look into this woman's mouth." What are you talking about?"
It turned out that he was asked to translate lips. Xu Zheng felt a little helpless. It was not easy to get a set of mini simulation cameras.
When he approached, Team Yang and others moved out of the way. A computer desktop showed a picture of a female student chewing with her head down. It looked like she was talking to herself. However, everyone present in the conference hall did not dare to be careless, fearing that the female student was chewing. Everything a student does has some meaning.
Xu Zheng observed for a while and then shook his head, "My dear leaders, if I can't do anything, her lips won't move and move, but there is no rhythm and there is no way to translate. Anyway, in the voice I know, it doesn't match her."
Detachment 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 secondary screening.
In just this moment, another 40 or 50 people from the hundreds of suspicious targets left. Now there are still 60 or 70 people at the high-speed rail station. Among them, more than 20 people are heading to Hongqiao Airport. Detachment Yang asked Xu Zheng to help with the key points. Observe these twenty people.
In fact, the information of these twenty people has already been investigated by the Shanghai police, including the air tickets they ordered, especially the fact that more than a dozen of them purchased international flights, 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 basically these people did not deliberately avoid the cameras, and their words and deeds were the reactions of ordinary people, including lip translation for them. It is due to the shortcomings of the parents and the expectation of a foreign country.
This is simply ineffective monitoring and a waste of the energy of investigators.
Xu Zheng felt that the arrangement of the Yang detachment was not very good, but he could not think of a better way. Now the stupid method has the advantage of stupid method, that is, whoever these people meet will be caught by the camera.
Even the bathrooms in Hongqiao are equipped with monitoring equipment, which can be said to monitor the entire Hongqiao building 360 degrees without blind spots.
The plane from Australia has already landed at Hongqiao Airport, and now the passengers are getting their luggage to prepare for the station. Unlike the high-speed rail, there is only Hongqiao's own security check at the airport exit, and the police are not involved. Xu Zheng is curious But I didn’t ask, probably because there were too many foreigners, and the leaders above did not approve 3D scanning of them.
Soon, the passengers of the plane walked out of the exit of Hongqiao Airport, and another target person that Yang's detachment was looking for was also among this group of people. It took more than ten hours for these passengers to fly from Australia to Hongqiao.
At this time, everyone seemed very tired, and they basically left Hongqiao Airport directly from the exit.
Of course, there were also a few people who took a short break and rushed to the Hongqiao High-speed Railway Station, apparently preparing to take the high-speed train to their next destination.
In response to this situation, Yang's detachment deployed multiple plans. In addition to using thousands of cameras to track and monitor the people staying at Hongqiao Airport and the high-speed rail station, he also sent a team of two plainclothes police officers on the ground to follow them.
But it's a pity that ten minutes have passed, and none of the people who stayed have met and communicated, as if they were really passers-by, or even met.
"Liu Bureau, could you please ask if there is anything unusual in the technical team?" Detachment Yang and Xu Peixin looked at each other. Could it be that the news they received was false?
Bureau Liu hurried over to inquire, but unfortunately, the various anti-reconnaissance electronic instruments deployed by the Public Security Bureau in front of their station found nothing suspicious.
Just when everyone was overwhelmed and overwhelmed, 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 getting off the plane is currently in the E6 smoking room. Look, he is the middle-aged man standing by the window. "
After hearing this, several leaders hurriedly walked to Xu Zheng's computer. Xu Peixin asked urgently, "Xiao Xu, please stop inking and tell me your reasons."
Xu Zheng switched the surveillance video to a drone camera. In the high-definition video, the female student was still chewing something in her mouth. This is normal. Some people can chew betel nut for a day.
But compared to half an hour, her expression has changed a lot...
Detachment Yang was responsible for today's arrest operation, but now it was seeing that the best arrest time was about to pass and their mission was about to fail. Xu Zheng was still here slowly explaining his reasons. He was a little anxious, "Xiao Xu, you can give me the details." Afterwards, just talk about how they communicated."
You must know that all the information exchanged by electronic devices in the entire Hongqiao will be detected, and the female student has been watching the video, and her mobile phone has not sent any information to the outside world at all.
"They use high-frequency microwave pulses to communicate with each other."
The person who spoke was none other than Hong Chenchen. Seeing that the police had not taken any action, he must have not identified the suspect, so he brought Qu Ying over and happened 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 could communicate over short distances without any electronic components.
Microwave pulse. Several of the leaders present are people of certain status and well-informed. They have heard of this short-distance communication method, but have never seen it. The main reason is that this communication method can only be used within 500 meters. within the range.
There shouldn't be anything particularly thick in the middle, otherwise the microwave pulses won't be able to penetrate.
The most unpredictable thing about this method is that it does not run on electricity, which means that there are no electronic components, no batteries, and no electron transmitters in this instrument...
Without these things, the counter-information detection equipment installed in this building by the Hongqiao Branch would be useless.
Seeing that some people didn't believe it, Qu Ying took out her mobile phone and found a set of photos, "Look, this is our unit's high-frequency microwave pulse transmitter. It is a very small thing, similar to a power bank.
There are two patches, one placed in the ear and one placed in the throat. The user uses the vibration of the throat to reflect the audio, and waits until the second user receives the microwave pulse.
This power bank-sized thing does the translation and transmission to his ears.
But what they transmit is not the sound of speech, but audio, and the recipient has to translate the audio into speech himself.
In layman's terms, you can think of it as two people communicating in Morse code five hundred meters apart, but it's not electronic information exchange, but audio. "
After saying this, everyone understood. Team Yang and Xu Peixin looked at each other and understood what the other party meant, which was to "catch" first, regardless of whether it was right or wrong.
After detachment Yang gave the order, the plainclothes police on the ground quickly rushed towards the 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 stunned, as if they did not know why the police arrested them. of.
Seeing the plainclothes policemen quickly evacuating the scene after catching the two men, Xu Zheng breathed a sigh of relief.
At this time, Director Liu suddenly remembered something and asked in a low voice: "Is this microwave pulse the monitor used by the Soviet Union on the beautiful country's embassy in the Soviet Union?"
Xu Zheng smiled and said: "Yes, it's that thing, but technology is much more advanced than that time. I remember this thing was invented in 1945. It's called golden lips. The people of Suzhou at that time were really smart.
They literally monitored the beautiful country for eight years. "
Hong Chenchen added: "The Soviet Union heard a piece of news back then, but it's a pity that we didn't pay attention to it. It's a pity..."
"Ahem..."
Before Hong Chenchen could say anything further, several leaders nearby covered their mouths and coughed at the same time. Good guy, young people nowadays really dare to say anything.
Bureau Liu looked at Xu Zheng carefully and sighed in his heart. This young man is worthy of being valued by the leaders of the ministry. His reaction is too fast and his knowledge is very broad. Most people can't think of microwave pulses.
Hong Chenchen came over and patted Xu Zheng on the shoulder, laughing and scolding: "You have come to Magic City a few times, but you haven't said anything 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 find you. It's just that I didn't come to Demon City on business, or I was captured. If you ask Mr. Xu, I don't have any free time at all."
Xu Peixin couldn't care less about catching up with them at this time, "Stop chatting now, 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 put in the interrogation room, and their bodies were searched. As for the reason used by the police, it was simply that they were reported by someone.
When Xu Zheng and the others arrived, the technical police from Hongqiao Branch were dismantling two power banks, with something like an earphone connected to them.
Seeing a group of leaders approaching, the head of the technical police quickly stood up and reported, "Dear leaders, this thing they have is not a power bank, it should be a short-range audio transmitter.
But the messages received and transmitted should have special secrets. Most people without training or their passwords cannot use this kind of thing. "
After hearing this, detachment Yang finally showed a look of relief on his face. Regardless of this now, as long as he can make sure that the person is not wrong, he looked at Xu Zheng and said gratefully: "Thanks to Xiao Xu this time, otherwise, let this person The two of them finished the conversation right under our noses.
It will be even harder to catch them in the future. "
Xu Zheng thought that these two people would definitely meet and do some kind of transaction. Unexpectedly, they just communicated for a while, probably discussing changing the transaction location. In fact, he was a little scared. If he didn't have the audio recognition technology given by the system, I really don’t know about microwave pulses.
If you don't know about microwave pulses, then today's mission will definitely fail.
If it failed, he would not only be embarrassed to get a simulated camera, but also embarrassed to ask for a computer 3D scanning instrument.
Fortunately, the results are good now. Now that the Yang detachment has determined that the target people they want to arrest are female students and middle-aged people, it means that Xu Zheng's mission is over.
As for the subsequent interrogation and other work, this is a matter for the Shanghai police.
Therefore, he quit as soon as he was ready and immediately said goodbye. Detachment Yang and Mr. Xu did not 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. Let's make another appointment after I finish the work at hand."
