Outside Linyang Prison, Zhou Liuyi was playing with his cell phone and Lei Ming was looking at his watch. They came here to pick up an important person, and it would take more than half an hour.
Lei Ming asked Saturday:
"You finally have a day off, why don't you go back to see Aunt Luo?"
Saturday smiled and said:
"I called my mom, and she said she was even angrier when she saw me, and told me not to go back, so that I wouldn't have to wash my clothes and cook for me, eat my fill, and then run away again, leaving her alone at home and feeling sad."
Now, his mother has changed the notes of him and his sister Zhou Qian to "ungrateful wolf number one" and "ungrateful wolf number two".
Saturday Question:
"And you?"
Lei Ming shrugged:
"My mother and Uncle Qin went on a trip and didn't want to take me with them."
Lei Ming did transfer 3,000 yuan to her mother so that she could have more fun, but her mother not only refused to accept it, but instead asked her to buy some cosmetics and clothes. She was already at the age of dating, but she had never even had a relationship. Just like her father, she sold everything to the company...
What a critical hit.
Saturday's question to Lei Ming:
"Why don't you have a relationship?"
Lei Ming said indifferently:
"How can we get along if a man has no secrets from me? People always need their own private space and don't want to expose all aspects of themselves to each other, but this happens to be my job.
It's good that you are still in touch with your former beautiful female colleague. In our line of work, we need some non-professional friends so that we can feel that this world is still quite lovely and not full of criminals.
We need some exposure to the normal world.”
The smile on Zhou Liu's face suddenly became unnatural. He was now looking at Huang Qingmei's circle of friends. Huang Qingmei had resigned and was now working as a kindergarten teacher. The background was colorful cartoon characters and tiny children. Huang Qingmei was in the middle, teaching the children to dance and smiling happily.
The two of them chatted idly.
Saturday is very good at chatting with girls:
"You've become more beautiful lately."
Huang Qingmei replied:
"Of course. Doing what you love and getting paid, of course you will become more beautiful."
Then, she posted several selfies. She looked completely different from when she was in the police station. She had short hair with bangs, wore a brightly colored skirt, and the bag she carried was changed to a cartoon style one.
We were having a pretty pleasant chat.
But Lei Ming said this, Zhou Liuyi hurriedly asked:
"Xiao Ming, how did you find out?"
Lei Ming stood with his hands behind his back:
"In a word, it's professional sensitivity. If you have to ask for a reason, it's that you're always smiling without any burden. Basically, you can rule out your bad friends. Boys and brothers won't smile so sweetly, unless they are gay.
Replying to messages from time to time can also rule out relatives. I don’t believe you and your sister have so much to talk about.
At your age, you have strong hormones, strong curiosity and like new things, but there are few girls in our industry who are lively and idle, so you are probably having a hot affair with a girl who is not in the industry.
As for why I think it was your former colleague, it is mainly because I also know your social circle. You have long stopped playing with those classmates from junior high school and high school. They think you are childish and you think they are stupid.
I have met your previous colleague Huang Qingmei. Even if you don't send her messages, she will send you messages frequently.
Right?
Even people guessed it, it was indeed Huang Qingmei.
In fact, Zhu Jiayin also sent him a message, but he just didn't want to reply. Zhu Jiayin herself is a graduate of the police academy, and as he investigated the case in depth, he now has the style of a professional police officer, digging deep into the matter and doing analysis.
Looking at those messages, Zhou Liuyi really had no interest and just pretended not to see them.
Shi Wenwen also sent me a lot of messages, asking if there were any recent cases that could be featured in special topics. The case of Lin Qingqing that she sent me received an even greater response.
Lin Qingqing is a person with an antisocial personality. Even though society doesn't owe her anything, she insists on disguising herself as a victim and wielding a knife against the weaker ones.
After this analysis, Zhou Liu subconsciously looked at his entire body. In front of Lei Ming, he seemed to be running naked without any clothes on.
Lei Ming looked at his watch again:
“Time goes by so slowly.”
At this time, a criminal police colleague called Lei Ming to ask about some clues and sent him a photo via email.
Zhou Liu took a look at it, but his brain hadn't reacted yet. However, Lei Ming said naturally:
“The surveillance camera captured a woman, but she was holding an umbrella and wearing a mask and sunglasses, so her identity could not be confirmed, so other details about the house were needed.
A broken hairpin was found in the trash can. The woman was probably from the north. I have never seen women in the south use such a big hairpin. They generally think that hairpins look rustic.
Wait, these noodles are relatively wide, and that’s what people from the Central Plains eat. Even people from Shanxi rarely eat noodles this wide as their staple food.”
Lei Ming enlarged the picture:
"The woman is wearing work shoes, which don't match the style of her skirt. Who would wear such a seductive skirt with such a flat-soled cloth shoe with only one button on the surface?
They should have been worn when going to work. Only slightly larger beauty salons wear such shoes. Go to a nearby beauty salon and look for people whose hometown is Central Plains. They should be similar.
In particular, look for surveillance time when people come out of the store.”
In order to ensure the accuracy, Lei Ming also took screenshots of the shoes in the photo, and then searched for the same style on the e-commerce platform on his mobile phone, and was sure that they were the shoes from the beauty salon.
The colleague over there breathed a long sigh of relief:
"Xiao Lei, you are too fast. If we were to investigate, it would take several days and the person would surely have escaped. Thank you. I will treat you to a meal later."
Lei Ming's lips curled up slightly, his face bright:
"No need to thank me, don't worry about it, because there are people lining up who want to treat me to a meal because of this."
If a man said such words, it would be a bit too proud and make people feel uncomfortable, but when such a beautiful female police officer said it, it would only make people feel amazing.
After hanging up the phone, Lei Ming put his hands in his pockets and asked Zhou Liuyi:
"By the way, what did you want to tell me just now?"
Zhou Liu was dumbfounded. What kind of man would such a smart and skilled female detective need to escape her eyes?
Originally, Zhou Liuyi didn't believe that women couldn't find a partner because they were too outstanding, but when he saw Lei Ming standing in front of him, he believed it.
Saturday shakes his head:
"No, no, I have nothing to say..."
He was sweating profusely. He just debugged a plug-in program last night and sold it for some money. It was a little illegal, but it wasn't a crime either. The government wouldn't investigate and the people wouldn't report it. He could make a lot of money. He really couldn't resist the temptation.
The buyers sent him dozens of pages of messages, so he was just trying to help others.
Then, I watched some porn movies late at night out of boredom, and even had an anonymous argument with the original poster on a sensitive topic... None of this was very glorious, would Lei Ming have discovered all of it?
Fortunately, the time came and the prison door suddenly opened. A man with a labor camp inmate hairstyle and wearing dirty shoes that were most popular two years ago appeared, holding a backpack in his hand.
Long-term prison life has a great impact on people. For example, they feel that the world outside the prison is too big. Different from the exercise ground and the narrow cell, people feel a little timid, so they are afraid of the clear sunlight that covers the entire open space.
He was a little surprised to see someone pick him up.
"You are my friends?"
Lei Ming ignored him, and Zhou Liu came over and took out a pair of handcuffs and his ID from his pocket:
"Hello, Ji Yunbing, I am Zhou Liuyi, a police officer from the Sanjiang City Anti-Fraud Center. I am now summoning you for an online fraud case. Please cooperate with the investigation."
Generally speaking, at this stage, the police already have substantial evidence, and the only thing left is a process to establish a chain of evidence.
So, Ji Yunbing immediately turned pale, like a frost-bitten eggplant, and stood aside, while Lei Ming was going through the handover procedures with the prison police.
In other words, Ji Yunbing had just finished his jail term for online money laundering, and now he has been transferred to the Sanjiang City police for online fraud. He was first thrown into a detention center, and will continue to serve his jail term after the investigation, trial and sentencing.
Ji Yunbing even laughed at himself:
"I have a stable job, right? Three years and three years. When I get out, I don't know what the world will be like. According to Moore's Law, transistor technology is updated every 18 months. I have been in prison for three years now. If I continue to do so, I will definitely have no choice but to sell sesame cakes on the street when I get out.
No, nowadays, those who sell snacks outside are thinking about how to attract traffic on e-commerce platforms and turn themselves into an Internet celebrity store.
I don’t know how to use these new technologies.”
Saturday smiled and said:
"No, fraudsters always put old wine in new bottles, no matter what kind of shell it is, from the earliest tulip scam, to p2p, to the current 1042, it will eventually become a Ponzi scheme. The person in front collects the money from the person behind, and his mouth is full of oil, while the person behind can only go to the rooftop."
Ji Yunbing nodded:
"That's what it is, officer. You are very insightful."
Zhou Liuyi couldn't help but hold his forehead:
"You've been in prison for three years, why haven't you been reformed yet? You haven't even been released yet, and you're thinking of committing crimes again?"
Ji Yunbing had handcuffs on both of his hands, so he couldn't just spread his hands out:
"Officer, have you seen my resume? When the three major operators were switching from 3G to 4G, I was dealing in data packages. Cat pools were not for sale, and half of the black market operators in Sanjiang City were using the ones I modified.
Later, this video went viral. It was me who started to get a bunch of second-hand mobile phones, bargaining them down a bit and increasing their traffic to get a few dollars or a few cents.
When I was in prison, I traveled thousands of kilometers to deal with online fraud and money laundering, and collected a lot of cards from mountainous areas.
Tell me, what can I do after I get out?
Open a mobile phone repair shop on the street? I learned quite well in it, better than the teacher who taught me. He often asked me to tutor others.
But, does anyone still repair cell phones now?
When I came in, two mobile phone repair shops on the street had closed down.
This is like being a eunuch in the palace for 19 years."
…
Ji Yunbing had a lot of complaints, which had obviously been accumulated for three years. He couldn't finish them in one breath, so he asked Zhou Liuyi to give him a bottle of water before continuing.
When Lei Ming came back from his work, Ji Yunbing was still talking nonstop:
"Nowadays, if you engage in illegal activities, you can still catch up with the last wave. The simplest way is to set up a pirated novel website with 3,000 yuan. You can make money and let readers register. Just fill in your ID number, name, password, etc., and it will be your own database dictionary..."
Lei Ming frowned:
"Xiao Zhou, everything he said needs to be sorted out and then handed over to Director Liang."
Saturday smiled and said:
"I see."
Then, Zhou Liuyi raised the recorder in his hand, and Ji Yunbing's eyes widened like a frog, shocked to the extreme:
"You, aren't you an ordinary auxiliary police officer?"
Saturday one:
"When did I say I was an auxiliary police officer? I am a technical detective at the Anti-Fraud Center."
Ji Yunbing leaned back in his chair, completely depressed. He looked at the scenery outside the car window:
"Well, freedom is definitely out of my reach in this life."
As soon as Saturday drove, Lei Ming was in charge of guarding the car. When passing by a KFC, Ji Yunbing swallowed his saliva:
"Can you buy me a family bucket?"
Lei Ming's face turned as cold as ice.
Ji Yunbing pleaded:
"I'm about to go back to jail. At the prison store, I can only buy Coke in plastic bottles. There's no canned Coke. There aren't enough bubbles in it, and there's no ice. The best Coke is the one in KFC and McDonald's, which has lots of bubbles and ice..."
As he was talking, Ji Yunbing started to cry:
"Why should I commit a crime? Others can eat at KFC and McDonald's and drink milk tea with their girlfriends outside, but I can only operate a sewing machine inside and eat pig food..."
Ten minutes later, Ji Yunbing ate the whole family bucket, poured ketchup on it, and drank Coke with his handcuffed hands. He drank a large cup in one breath, and then burped with satisfaction:
“It feels so good!”
Lei Ming looked at the Coke and hamburgers and didn't think they were tasty. For the policemen born in the 1970s and 1980s, what they ate most when they worked overtime was instant noodles and sausages. However, for the policemen born after 1995, what they ate most was takeout and these fast foods.
It’s simple, convenient and open 24 hours a day.
Lei Ming is a policeman born after 1995.
She asked:
"What are you going to do after you get out of jail?"
Ji Yunbing looked at Lei Ming's pretty face, but didn't dare to act rashly:
"When I get out, I will buy a copy of the Criminal Law first, and then I will resolutely not do anything that is not allowed in the Criminal Law."
Finally, he said something sensible.
The vacation had just ended, and Liang Peihe made some adjustments to the staff. In fact, he didn't adjust many people, just Sheng Changfeng and a few others. Those who were not selected felt very sorry.
Liang Peihe is a front-line leader in handling major cases. He usually handles cases that others dare not easily take charge of. He seems to be sitting on a powder keg, but after handling a case, he can stand out among other people of the same level.
Some people may only work with Liang Peihe on one case in their entire life and then switch directly to clerical work, but in the eyes of others, that is an outstanding achievement.
Moreover, Liang Peihe is already old, and it is difficult for him to continue working on the front line. A large economic investigation case takes several years to handle. If he loses this opportunity, he may never have it again.
This group of people seemed very depressed, and Liang Peihe boosted their morale;
"The office where we store cases is full of files. My office was originally over 40 square meters, and now I have partitioned off 30 square meters to store case files, but it is now full again.
What I want to say is that, from now on, whether it is in our Sanjiang City or in the whole country, anti-fraud work has always been the top priority. Those who have not entered my team will enter other teams.
Our generation of police officers is not facing bullets and gunfire, but criminals with greater destructive power who are separated by Internet cables and mobile phone screens.
I will work hard with everyone.”
Those who were not selected were not able to accept such an explanation, but nowadays, in the stage of finding clues in online fraud cases, there is really no need for so many people.
Liang Peihe added:
"As the case progresses, I will come back and ask for your help."
Then everyone had a look of joy on their faces. Liang Peihe couldn't help but shook his head. People born in the 1990s and 2000s are not easy to fool nowadays. They must see the truth.
In the absence of many clues, this task force has now been established.
It’s not that Liang Peihe doesn’t want to use the human wave tactic, but as Zhou Liuyi said, the human wave tactic is not only useless for network technology, but will drag down the entire team.
Liang Peihe called a car and started giving everyone a crash course on the way:
"We need to understand the criminals' thinking and techniques. Knowing ourselves and the enemy will ensure victory in every battle. I have found someone to explain these things in detail..."
Everyone was looking forward to it. Fan Di even straightened his collar. He thought the person coming might be an expert at the provincial or ministerial level.
However, the destination of this police Iveco was actually the detention center in Sanjiang City. This place was called Sanxian Mountain. It used to be in the suburbs and the largest gas station was also located here. But in less than ten years, it became a development zone.
There is such a large detention center, and the surrounding residents have protested countless times. They have bought houses that cost tens of thousands of yuan per square meter, so how can they be so close to the detention center?
But the deputy director of the detention center was from the pre-trial team. If nothing else, he had a big mouth and was the one who always spoke out:
Our detention center has been here since it was still a cemetery. Why should we move?
The land for your current neighborhood was leveled by me and the prisoners myself. Now you complain about the bad feng shui, so you want to sue the developer?
Three high walls and barbed wires inside and outside, iris fingerprints and various new technologies, we are the first to use them. I have never heard of any prisoners escaping from prison. If you have heard of it, please give me the contact information of the person who spread the false news. I will sue him for spreading rumors! Spreading rumors that there are escaped prisoners will be subject to legal responsibility!
…
The detention center was originally a relatively low-key place, but with such a deputy director, it has almost become a landmark building in this area.
Liang Peihe, actually brought people here?
Fan Di always follows the leader's steps. He said to everyone:
"Director Liang has his own arrangements. There must be a big shot who needs to show up and explain himself, so he brought us here."
Liang Peihe held his forehead with his hand.
In this world, the majority of people stick to conventions because of their occupation, gender, social status and the education they have received.
People like Zhou Liuyi are a minority.
Liang Peihe was originally racking his brains to figure out the problem. Zhou Liuyi did not have a day off and was still playing games in the dormitory at night, so he took Zhou Liuyi out for a walk.
Saturday Question:
"Aren't opponents the best teachers? Since the Internet was launched in 1994, we have caught many people who committed Internet financial crimes, right? Telecom fraud and point-scaling are very tricky now. Can't we just find someone in prison and ask him?"
Is it that simple?
Liang Peihe even found this idea a little unbelievable.
Saturday one:
"I know that there are many experts in our industry , like Jiang Hanshan and Song Xuewen in drug enforcement. Dozens of pictures of flowers are placed in front of them, and they will just glance at them and buy up the poppies.
In image detection processing, there are people like Jing Heming who can directly draw the appearance of a suspect from the confessions of several people, which can be recognized by computer.
During this period, the experts sent down from the ministries and commissions are not very old, but they have outstanding achievements and can hack into the official websites of foreign countries.
But these things are far from what we need. We can look up to the forefront of technology, but we need something that can be used directly. "
Liang Peihe frowned.
How can a cat catch a mouse and learn techniques from the mouse?
Saturday one or two hands spread:
"Anyway, my family has been selling instant noodles for so many years, if sales drop, we will just ask why people don't come to eat.
In my family, the noodles in the summer have to be rinsed with cold water, and the peppers on the table in the winter have to be spicier.
Sometimes, even the chef himself cannot feel the difference, only the customers who eat it can understand.
Only your feet know whether the shoes are comfortable or not."
The survival wisdom of the common people is so simple and straightforward.
Liang Peihe thought about it all night, and the next day he asked Zhou Liuyi and Lei Ming to go and pick someone up.
Ji Yunbing's case was examined in the most detailed way possible. The case file was nearly 4,000 pages long, with more than 300,000 words. The police officers at the time were tortured terribly, and some even complained that they never wanted to see this guy again.
It's not realistic to show so many things to the police, so it's better to just pull the person over and let him speak for himself.
Moreover, there happened to be a case in which Ji Yunbing was to be transferred to another place of imprisonment.
Such a person is perfect.
Liang Peihe, Guo Shengli and Xie Min discussed it.
Guo Shengli thinks Liang Peihe is crazy:
"I've never heard of a mouse being a cat's teacher."
Xie Min was more serious:
"Be careful, be cautious, don't tell anyone, everyone will laugh at you. You have no other options for the case, and you actually came up with this stupid idea."
Ji Yunbing, wearing handcuffs and drinking Coke, also found it incredible:
"No way? Policewoman, I'm a sinner. Do you want me to explain to you what crime is?"
Lei Ming remained calm:
"You are an expert in this area."
Zhou Liu took out the case file with an innocent smile:
"I've read it. If your partner hadn't used a plain text password and the police hadn't used a dictionary to crack it, you probably wouldn't have been caught."
Ji Yunbing seemed a little embarrassed:
"My biggest problem is that I don't know how to judge people. You can actually finish reading such a boring thing, one-third of which is nouns. How can you be a temporary worker? I really underestimated you. In our industry, the younger you are, the more destructive you are..."
As he spoke, Ji Yunbing looked at Zhou Liuyi with ill intent:
"You don't want to take the test first to see how the police handle cases, and then hide from the police while you make money, right?"
The way Lei Ming looked at Zhou Liuyi had changed.
Zhou Liuyi was about to defend himself, but Ji Yunbing said with certainty:
"Once you've done it once, you won't care about that little salary anymore, unless you work for a super large company. But most of those who work for a company are just supported by the Internet giants at a high price. Don't do sabotage again. As for people, once they live a comfortable life, their skills are basically useless..."
Zhou Liu held his forehead with his hand. He now understood why Liang Peihe asked this guy to come and give lectures, because Ji Yunbing's ideas were completely criminal, wild and unrestrained.
Of course we can’t let Lei Ming stand by and watch the fun.
But if he admitted that he sold plug-ins, that would be a crime. If he didn't admit it, Ji Yunbing would think he was incompetent, so he just studied for a few days and entered the system to get by.
Zhou Liuyi looked through Ji Yunbing's resume:
"Did you trade train tickets during the Spring Festival travel rush in 2013?"
Ji Yunbing nodded.
In the early days, the black industry had not yet become rampant, and many people who worked in unconventional ways could not sit back and enjoy the fruits of their labor. They had to run a lot of offline business just to make a living.
Ji Yunbing was one of them. He nodded:
"Yes, the online train ticket purchase system has only been online for a few days, and the tickets have been snapped up. Many people don't have smartphones yet, so they can only gather at the train station to queue up, but they can't buy tickets even if they queue up.
I tried my best to get a ticket, and it was common to pay 80 or 90 yuan for one ticket. Later, everyone used smart phones, and they bought tickets more than half a month in advance, and a part of the tickets were released every day.
This money is not easy to earn. "
What Ji Yunbing meant was that he had always been following the trend and engaging in the most profitable small black business.
Saturday with a bright smile;
"Do you know who made the ticket grabbing software you used at the time?"
Ji Yunbing's eyes looked a little uncertain:
"I remember it was a person named Liuyi. We all thought that this name was too childish, sounded weird, and lacked trust. But at that time, another person gave us some knowledge, saying that the younger the person, the more powerful they are and the faster they think..."
Saturday took out his ID card:
"Who do you think I am?"
Ji Yunbing's sloppy face suddenly changed color, and then he sat up straight:
"That's impossible! How old were you then?"
I took a look at Lei Ming on Saturday:
"I was not very old, maybe in my teens. I just saw that there were too many people who wanted to go home, but it was too difficult to buy tickets, so I wrote this program. It was very simple to write such a program at that time. It was nothing more than simulating crazy mouse clicking and competing with others in hand speed..."
The technology that everyone thought was amazing was just a piece of cake according to Zhou Liuyi's description, and he posted it online for free for everyone to download.
All later accelerators require money or additional fees.
Lei Ming didn't show much expression. After gradually changing from selling rice cookers in the electronics city to selling mobile phones and computers, Zhou Liuyi had been working there all the time, earning a lot of money. He could also repair her mobile phone and make her stuck computer run smoothly by writing code, so she was no longer surprised.
Moreover, she had seen Zhou Liuyi assemble a computer with various scrap circuit boards and diodes that he had bought at the electronics mall. He even set the computer to English and reversed all the programs and execution commands inside it...
Once upon a time, when Lei Ming first came into contact with a computer, the teacher vowed that no one could memorize 10,000 lines of code.
But at that time Lei Ming overturned the teacher's words in his heart.
You can do the same thing you memorized on Saturday.
It is certainly impossible for others who have already worked hard in society and make a living by typing on the keyboard, but a ten-year-old boy has long summer and winter vacations and can do this without distraction.
He has no reference system and does not need to consider anyone's opinion. The only criterion in his mind is himself.
Until now, whenever I encounter weekend scheduling, data retrieval, or even college class schedules, I will habitually write a small wheel on Saturdays and Mondays so that I can retrieve it accurately at any time.
His pursuit in this area is like a math expert memorizing the multiplication table, which is child's play.
Ji Yunbing murmured:
"Before, everyone said that those with the best skills were all recruited by the country. I didn't believe it, but now I believe it."
Saturday, I asked Ji Yunbing:
"So, can we talk now?"
When Lei Ming and Zhou Liuyi brought their people in, everyone was shocked. The person who came was actually a criminal who had just been released from prison and was about to be imprisoned?
Isn’t Liang Peihe’s idea too unconventional?
They actually let criminals teach the police officers who are handling the case? It's unbelievable and out of this world.
Liang Peihe briefly introduced:
"Everyone, please be alert. This person is a true expert in financial computer crime. He has committed many of the cases we are currently handling. He can provide more details and help your future work."
A group of young policemen still had some doubts. They had the information of this man in their hands. Ji Yunbing was simply a walking textbook of Internet black market crime. He had committed almost all the cases.
But Ji Yunbing looked at Zhou Liuyi with a bit more awe in his eyes:
"I think this officer is more capable than me. There are some things I didn't explain clearly. I would like to ask this officer to explain more."
Although Ji Yunbing knew more, Zhou Liuyi handled more machines and his hands were covered with calluses.
Zhou Liuyi is young, but has a long working experience.
