Provincial People's Hospital, Interventional Ward, when Xu Zheng and the others walked in, Professor Chi Guoming was standing in front of the window chatting with a doctor wearing glasses and a white coat. When the doctor turned around, it turned out that it was the doctor who had just Fu Xuerong was promoted to director of the interventional department.

It is said that he is also a student of Professor Chi Guoming.

When Chi Guoming saw Director Nie coming in person, he hurriedly stepped forward and asked, "Why did Director Nie come in person? Is there any clue about my matter?"

Director Nie held Chi Guoming's hand and said with a smile: "Based on our investigation results and with the approval of superior leaders, we will not prosecute. However, within these three months, we hope that Professor Chi will not leave Changming. If he must go out, , such as treating a disease, just report it to us."

"Alas..." Chi Guoming sighed, looking haggard, "To tell you the truth, I only have one month left in three months."

Fu Xuerong, the new director of the interventional department next to him, looked bitter, "I was just trying to persuade the teacher that his disease can be operated on. If the operation is effective, he can still live longer..."

"No, no need." Chi Guoming said cheerfully: "The operation is very effective. It is indeed possible for me to lie down in the hospital bed and survive for a year and a half, but I cannot speak or get out of bed. I live by injections and infusions every day. This is contrary to my philosophy and I don’t want this.”

Chi Guoming's children are married and his parents have passed away. The only one who has some memories is his wife. However, most couples who are doctors do not have a good relationship and live a makeshift life. Therefore, he has no desire to persist in living.

Moreover, surviving in pain is indeed not a philosophy he has always adhered to.

Xu Zheng took out the release document issued by the Municipal Bureau and handed it to Chi Guoming with both hands, "Professor Chi, please take care of yourself!"

Only in the past few days did Chi Guoming find out that his affairs had affected Xu Zheng's work. He was filled with guilt. He held Xu Zheng's hand and said slightly excitedly: "I didn't expect that my affairs would affect your work." , and you can’t even work as a detective..."

Xu Zheng interrupted him quickly, "No, no, Professor Chi. On the contrary, I changed my job this time and got promoted. As for being a criminal police officer or not, any job is a good job as long as it can catch bad people."

After all, this was not the place to talk. Director Nie and Team Wan chatted with Professor Chi for a while before taking their leave.

As soon as he left the ward, the system's voice rang in Xu Zheng's mind, and it rang several times in succession, [Ding, congratulations to the host for completing the hidden kill list mission. 】

[The system rewards the host with advanced language talent. Note: Advanced language talent can improve the host's ability to learn various languages ​​tenfold. 】

[The problem of slow update of new chapters is finally solved with an app that can change sources. Download it here

[The next cooling time of the system hidden kill list is six months. The host can complete various software to speed up the cooling of the hidden kill list. 】

Xu Zheng was surprised and happy by the three system sounds. He was surprised because he was surrounded by leaders, but he was happy because of the new abilities given by the system.

Advanced voice talent.

The system is indeed a considerate person and knows that he needs to learn various dialects. With this ability, it will no longer be as difficult as learning English in school.

It's just that this ability is a bit unworthy of the name for ranking ninth on the system's hidden kill list. He thought for a while and it should be Professor Chi. He didn't put in much effort, including the investigation of Professor Chi's hundreds of patients. All the work was done by Wan Detachment. People investigate secretly.

It seems that what the system rewards does have a lot to do with his own participation in the case.

There were a lot of people in the elevator. Director Nie and Team Wan clearly felt something was wrong with Xu Zheng, but they didn't take it to heart. They just felt that this guy was a little obsessed with investigating people.

Zhou Youfang and Jiang Lanxin's children were abducted. How could they find out so easily? Facial recognition, various high rewards, interrogating hundreds of traffickers... They have exhausted all the anti-trafficking methods in various provinces, and they have not found them for so many years. , Xu Zheng found new clues this month, which was as difficult as climbing to the sky.

But having said that, if you are not a madman, you cannot become a Buddha. The investigator who is obsessed with love has to be in this state. Occasionally, even in a dream, an idea flashes, and this clue comes.

On the way back, Director Nie admonished Xu Zheng, "Are you going on wedding leave starting tomorrow? When you get back, prepare for the wedding. These two are abductors. Let's continue the investigation after your wedding leave is over."

Wan Haihong also meant the same thing, "Your family is basically worried about your wedding. Work more when you go back. You can't do work secretly.

With your temperament, if you are at work, good guy, you will definitely forget about food and sleep, and your wedding will be delayed, which is a big deal.

If that's the case, your grandma can't blame us for treating you too harshly. "

Xu Zheng could only giggle. He is such a person. When he works, he will indeed forget the time and indulge in the idea of ​​​​solving love affairs. Outsiders think it is boring, but only people like them will feel that the flash of inspiration is the same. A joy.

Back at the detachment, Xu Zheng got into a small conference room again. He was too lazy to go back to his desk now. He even stopped attending the morning meeting and devoted himself wholeheartedly to the anti-trafficking files.

This time, he unknowingly opened the file of Jiang Lanxin's daughter Yan Mo. The girl was two years old when she was lost. At about 11 o'clock in the morning on February 16, 2022, she was killed at the Tianhaoling Temple Fair in Longkou City, Zhongping Province. People abducted.

The Tianhaoling Temple Fair has an average daily attendance of 400,000. After her child was lost here, Jiang Lanxin immediately shouted to passers-by for help, but the crowds were so heavy that her and her husband's voices were drowned in the crowd.

The police who were on duty at the temple fair arrived at the scene within three minutes, but there were too many people coming and going. What was disappointing was that when the child was lost, none of the passers-by standing nearby came forward to testify or provide clues.

What’s even more pity is that there are no cameras on this stretch of road.

Although the local police collected videos within an hour after the child was lost, they watched the videos hundreds of times and found no suspicious person, let alone any trace of the child after he was lost.

Xu Zheng has been looking through the thousands of hours of video these past few days, and he has basically finished watching it. He originally wanted to ask for help from the picture scouts of the picture scout detachment, but this person was not from the detachment. This is his private matter.

It's definitely not okay to use police force to handle his personal matters during working hours.

Several colleagues from the second brigade wanted to come over to help him after get off work, but he refused. In fact, he also knew that it was difficult to find clues in these videos. According to Ye Tao, the provincial anti-trafficking office, their anti-trafficking office would re-watch videos like this every year. It's just that the result is very disappointing.

The 12-year-old girl is now with her adoptive parents. Facial recognition can identify her appearance unless she is seriously ill or disfigured or otherwise unforeseen.

Unless the child encounters some unexpected circumstances.

A serious illness in childhood may affect the child's appearance, especially when the child's teeth are changing. For example, the child's mouth is full of cavities, which will definitely affect her appearance when her teeth are changing.

It is also very easy to cause dental caries in children. Excluding drug factors, you only need to let the children eat sweets every day and not brush their teeth. After half a year, the child will be guaranteed to have a mouth full of dental caries.

Xu Zheng thought of this and patted his forehead. Is it necessary to conduct a nationwide investigation on the little girl who had cavities on her teeth seven or eight years ago?

This is simply whimsical. To check these, it is better to register the DNA of all people.

But this idea also gave him new inspiration, that is, what would dental caries make of this little girl? In this regard, he drew some pictures of her 12-year-old based on the photos of two-year-old Yan Mo.

To be honest, regardless of the cause of dental caries, the photos he drew are almost the same as those simulated by the aging software. Obviously, this kind of photos will definitely not work. If it works, children will definitely be found in today's society.

After all, children's school registrations nowadays are all online. There are photos on the school registrations, which can definitely be checked under the national network.

It is not found now, which means that Yan Mo has changed a lot since she was a child.

At present, Xu Zheng feels that changes in appearance caused by dental caries are also one direction. The other reason is that Yan Mo suffered a serious illness after being kidnapped. General anesthesia, for example, can also affect appearance.

Also, for example, if she is a native of the Central Plains and is suddenly abducted to Yunnan and Guizhou and other places, the unsuitable soil and water, as well as environmental and other factors, may also cause changes in appearance.

Although Xu Zheng now has advanced simulation portrait technology, he has never drawn this kind of portrait before. It is impossible to draw and there are too many changes. But now he wants to give it a try. After all, face recognition has been able to help the police since its advent. Many abducted children were found.

For example, ten years ago, the Mr. Guo's abducted son was found by the Truong Binh Province police using facial recognition technology.

This kind of research needs to consider various factors that lead to changes in a child's appearance as he grows up. He certainly cannot do it alone, he will need helpers.

Zheng Heming from the Provincial Picture Scout Corps and his apprentice Qi Guangyuan from the Municipal Picture Scout Detachment are both good simulation portrait masters. I wonder if they are interested in coming to help.

Thinking of this, Xu Zheng did not hesitate and directly picked up his mobile phone and called them. As expected, both of them were interested in the topic Xu Zheng talked about, especially Zheng Heming, who had been working for almost thirty years and still Really studied it.

He was very interested in the phone call and directly invited Xu Zheng to his studio. There were materials he had collected over the years. He was now studying it as a topic. His superiors even approved him a million research funds every year, but , since his project was established five years ago, no results have been produced for so many years.

This time Xu Zheng happened to coincide with his topic. Before the phone was hung up, Zheng Heming hurriedly assured Xu Zheng, "Xiao Xu, just come to my place. I will personally call Director Nie to ask for leave." ..”

Naturally, Xu Zheng didn't let him make this call, because he was now a free agent of the second brigade, and he didn't even need to tell Zhang Yuqi when he went out to do errands. However, when he went out, he still went to the brigade captain's office to inform him.

Zhang Yuqi was lowering her head to study the situation at this time. On 2.14, as the investigation deepened, the Second Brigade found out that the murderer may have used psychotropic drugs and hypnosis to commit the crime, but they could not find any trace of the murderer behind the scenes. .

Therefore, everyone has a sad look on their face these days.

When Xu Zheng said he was going to the provincial department to do something, Zhang Yuqi nodded and waved him away, but at the end she asked out of curiosity, "How is the anti-trafficking drug you investigated? Can it be resolved in a month?"

Xu Zheng smiled mysteriously, "I went to the provincial office to verify my guess. There is a 50% chance of success this time."

Zhang Yuqi became interested instantly. 50% was already a very high probability. "What's the situation? Can you tell me in detail?"

"I'll give you a break first. If it doesn't work out, I'll slap you in the face. Don't worry, if this trick falls through, it will definitely be reported in the name of our second brigade."

Zhang Yuqi immediately lost interest and waved her hand, "Get out of here and wait until you have definite information."

From the Pingjiang Provincial Public Security Department in Qinhuai District, Xu Zheng came with Qi Guangyuan. The two had a brief exchange on the road. He first gave Xu Zheng a brief introduction to Zheng Heming's topic.

The main purpose is to study the abnormal appearance changes of children during the entire growth process. He said: "The forest expert from Shandong Province actually studied this topic, but gave up. Later, he mainly studied the combination of simulated portraits and model lake portraits. A new method to solve the problem of unclear portraits in surveillance videos.

However, although he did not continue to study this topic, he still gave me a lot of advice as a teacher.

Maybe this subject is indeed very difficult, or maybe we people are not talented enough. After so many years, we have basically stagnated.

Because there are too many factors that can affect changes in a child's appearance, it is difficult for us to do it manually based on experience, and we have not found the correct algorithm for computers.

We have also cooperated with software development companies. Unfortunately, the data collected by normal aging software cannot be applied to the software we want to develop, so most of the funds are wasted on this. "

Xu Zheng scratched his eyebrows and said, "Lao Qi, I almost want to back off what you said. There are so many of you masters and apprentices, and your teacher is still a senior engineer in our Pingjiang Provincial Department. I feel that one more person is a waste. time."

"Fuck, you kid can't give in. If you go back halfway, my teacher will not skin me alive." Qi Guangyuan was very familiar with Xu Zheng because he and Xu Zheng shared private work, and naturally spoke very casually.

While the two were chatting and laughing, they arrived at the provincial hall. Qi Guangyuan led the way directly to Zheng Heming's studio.

It was Xu Zheng's first time here. As soon as he entered Zheng Heming's studio, he felt sour in his heart, because this studio was more than 100 square meters. His own studio was remodeled in a small storage room at home, which was less than 20 square meters. flat.

Sure enough, experts are treated differently.

But Xu Zheng's simulation portrait ability is definitely higher than Zheng Heming's, but it's a pity that the system not only looks at ability, but also based on qualifications.

Of course, he was not jealous of Zheng Heming, just a little emotional.

When Zheng Heming saw Xu Zheng and the others coming in, he immediately put down his brush and waved to them, "How about coming and taking a look at the picture of Autumn Mountains after the Rain that I painted?"

Qi Guangyuan smiled secretly from the side and said: "My teacher's quirk is that he likes to paint landscape pictures when he is excited, and gives them away after he is finished. You are lucky today. One meter of my teacher's paintings is worth tens of thousands of yuan."

Most of the hobbies of simulation portrait painters are painting. Basically, the higher the ability to simulate portraits, the higher the painting level of Chinese and Western paintings. For example, expert Lin from Shandong Province, a Chinese painting starts at 200,000 yuan.

Xu Zheng's painting ability is actually quite good. In terms of traditional Chinese painting, he has only studied portraits, and he can only have a vague understanding of landscapes.

No, Xu Zheng walked to Zheng Heming's desk and looked at his freshly painted landscape painting. He was very familiar with the landscape in the painting. It was the scene of Xiangshan Mountain in Liuhe District, so he blurted out, "Mr. Zheng's paintings are really lifelike. I You can recognize it at a glance, this painting is of Elephant Mountain, right?"

Chinese painting emphasizes the meaning of the painting rather than the scene. As soon as Xu Zheng said these words, Zheng Heming realized that this boy probably didn’t put much effort into traditional Chinese painting. He didn’t even have a teacher. Considering that he worked as a criminal police officer and was so busy every day, he didn’t really understand. Chinese painting is also normal.

Thinking of this, Zheng Heming lost interest in the landscape painting he had just finished on the table. He pulled Xu Zheng and pointed to the rows of bookshelves, "Here are the materials I have collected over the years. As for your suggestion that the period of tooth replacement affects appearance, .

I have also collected the appearance changes of several children, you can take a look first. "
