Originally, after the dance class, Shi Caixin, who was finally free, wanted to invite Yang Yan and Luoluo to a big dinner in return. But Xia Yu called, and Yang Yan could only tell Shi Caixin truthfully that they couldn't go!

"Do you have something to do too?" Shi Caixin asked with concern, "Why don't you help you take care of Luoluo?" Don't worry, just come back at night and pick up the children at our house! She plays with Doudou and has a companion!"

"Don't bother, I didn't take her to Xia Yu's unit before. Yang Yan smiled slightly, and politely declined Shi Caixin's kindness, "And today is the weekend, and there are only a few colleagues on duty in the unit, so it will not affect the past." ”

After class, Yang Yan took Luoluo to bid farewell to the Shi family's father and daughter and Teacher Liao in the dance training class, and drove to Huahe District in a hurry.

......

Xia Yu had been waiting under the provincial office building for a long time, she asked Yang Yan to register with the security guard, and then hurriedly took Yang Yan to the elevator.

Luoluo wanted to go by herself, she held her father's fingers, she was not in a hurry, she could still look curiously at the high-rise buildings standing around, but as soon as her mother came, the little girl couldn't keep up, let alone look left and right looking at the solemn and majestic decorations in the provincial hall building.

"Uh-huh......" She only heard Luoluo gasping slightly, and in order not to be left behind by her striding mother, she trotted a few steps hard. However, she couldn't keep up, she couldn't help but pout, wanting to protest with her mother and father, but fortunately, they quickly walked to the elevator position!

It's finally time to stop!

Luoluo stopped following her father's footsteps, in order to express her grievances, the little girl pouted, glanced up at her mother unhappily, and leaned on her father's thigh, dragging her father's fingers, like a pendulum, and gently turned around her father's thighs.

It looks like she accidentally bumped into it while she was trotting in a hurry, but in fact, Luoluo is quite athletic, and the brakes are quite timely!

The network supervision department is on the eleventh floor, and it will take a while to take the elevator, and Yang Yan is in the elevator, and he listens to Xia Yu's account of the current progress of the case.

Of course, Fengcheng was not able to find out "Jiang Chang" or a fraud organization behind this name! They used a more traditional method of tracking the flow of stolen money, but the clue was broken in this part of the online banking!

Miss Nie remitted money to the futures trading platform provided by "Jiang Chang" through online banking, and the information provided by the bank showed that the account number actually remitted by online banking was the account number of a personal merchant on an e-commerce platform, but by contacting the e-commerce platform, Fengcheng found that there was no way to track the flow of funds through this account, and the funds in its account were also cancelled after being transferred many times!

Obviously, the fraud organization behind "Jiang Chang" has a very hard foundation in technology, and it has certain anti-tracking capabilities!

In contrast, it is difficult for the grassroots public security bureau or police station to have the technical ability to detect such a high-tech crime case.

"Now Miss Nie is still in the Fengcheng Public Security Bureau, Fengcheng will actively cooperate with us to extract evidence and search for clues!" From Xia Yu's narration, it is not difficult for Yang Yan to find out how eager the Fengcheng police are to solve this case.

Without further ado, after Yang Yan arrived at Xia Yu's work table, he took over Xia Yu's computer.

It is worth mentioning that although it is also an office computer, the computer of the network supervision department is more brand-new and has a higher configuration.

However, for Yang Yan, who needs to use hacking skills, he doesn't think that this kind of ordinary computer configuration is enough, and he easily boarded the backend of the provincial server provided to him by Dai Guoxun - although the password has changed, he left a small hand before, and easily bypassed the supervision of the administrator and the system!

Then, Yang Yan took out a mobile hard drive from the bag he was carrying, connected it to the computer, and after a dazzling operation, he logged into a black interface.

This is a tool that Yang Yan wrote for himself, and it naturally lacks a little meaning in terms of aesthetics!

However, Xia Yu knew that he didn't understand, and he felt strange when he looked at it, and he wouldn't ask out loud to disturb Yang Yan's progress.

"You call Fengcheng and say that I will send a document to their deduction, you just let them receive it, you don't have to do anything, and then Miss Nie's mobile phone will be connected to the computer with a USB cable!" After Yang Yan finished debugging, he turned his head and said to Xia Yu.

"Okay!" Xia Yu responded neatly, and she took the landline next to her to call Fengcheng.

After a while, Yang Yan saw that the little Trojan he transmitted was received by the other party.

This little Trojan horse immediately built a bridge between two computers in different regions for Yang Yan, and Yang Yan also successfully took over the other party's computer.

After a while, a software appeared in the mobile phone system simulator on Yang Yan's computer interface, which was the futures trading platform used by the fraud group to collect money.

Next, there was nothing to do with Xia Yu and the Fengcheng police, Yang Yan operated silently on the computer in front of him.

"How is it?Can it be cracked?" Xia Yu saw the lines of code on Yang Yan's computer interface sliding like a book from heaven, and she waited for a while before she couldn't help but ask.

Yang Yan turned around and smiled, and said: "The person who wrote this software is a bit level, but I can still crack it, and besides, let me tell you, this software can still be used, and what can't be used is Miss Nie's account to log in to this software!

He said it lightly, but it was really lighthearted!

The technicians of the fraud gang have two brushes, but they are still far from Yang Yan, the real bull, Yang Yan peeled off the protective layer of this software like peeling an egg after a while, and the code inside was extracted by Yang Yan without reservation and analyzed!

Xia Yu saw Yang Yan's confident smile, and the anxiety in her heart gradually calmed down, she didn't turn around behind Yang Yan anymore, in order to give Yang Yan a quiet environment, she pulled Luo Luo to another position on the side and whispered!

"Hey, Xia Yu, didn't you say that your one is coming? Why did you see your daughter?" At this time, Lin Xiangxian, who had gone out for lunch, came back, and when she saw Luoluo, she laughed, "What's the name of the little girl?" The older she gets, the worse her memory becomes, I remember her surname Yang!"

In an unfamiliar environment, Luoluo was smirking unscrupulously with her mother at first, but suddenly a "strange" aunt appeared, and the little girl was startled!

I don't know if I feel ashamed that my laughter just now may have been heard, Luoluo quickly hid on the other side of her mother's thigh, and then she pressed her little hand on her mother's thigh, and her little eyes looked at the person with some fear and shyness.

"Sister Xian, are you back so early?" Xia Yu had already told Lin Xiangxian about a case to be handled today, and she had also mentioned that Yang Yan would come, so her expression did not change, and she smiled and said to Lin Xiangxian, "Her name is Luoluo, Yang Xiaoluo!"

"Haha, the child is still shy!Luoluo, do you remember Auntie?The last time I went to the zoo with you, that Xiaolei's brother's mother!" Lin Xiangxian greeted Luoluo softly.
