After Luoluo and her father and mother arrived at Grandma Li's house, they felt that the little girl who was a little strange here was snuggling obediently to her mother's legs. She didn't want to sit there, and she could still turn her body and secretly look at the strange decorations.

For example, a dark and shiny wooden cow placed on the TV cabinet attracted the attention of the girl. She pursed her little mouth tightly and looked at it for a while before turning her eyes to another place.

Not good-looking!

It's ugly, but it's still good-looking Xiaomi...

However, as she looked around, the little girl felt the grandmother's gaze! She raised her eyelids timidly to look at Grandma Li, and found that Grandma Li was indeed looking at her, and she was talking to her parents while looking at herself!

Well... don't...

Luo Luo grabbed her mother's knee with two little hands, a little restrained, and a little unhappy to twist her body gently, pouted her mouth and looked to the side.

It's like stealing a bell with his ears!

After a while, Luo Luo's big round eyes blinked again, and quietly turned back. She looked at Grandma Li secretly.

oops……

Grandma Li just glanced over again. The little girl was like a frightened rabbit and hurriedly turned her big, lively eyes back.

In fact, Grandma Li just felt that the situation of police officer Xiaoxia was a bit too big. It didn’t matter if she helped her solve the case and brought a “assistant”. She also brought a child here. This family member is strange to everyone!

That's why Grandma Li occasionally looks at this child, but she is very confused now, thinking about the money she was cheated of, she has no energy to ask Xia Yu, and she doesn't even gossip in her heart.

She didn't know that she looked at Luo Luo inadvertently, and her panicked and unconscious eyes made the little girl feel uncomfortable!

Luo Luo finally couldn't help it. She pouted her little mouth and left her mother's arms, and her little body quietly squeezed to her father who was a little further away from that grandma.

At this time, Yang Yan was busy using a screwdriver to install some equipment on the phone, and he had no time to pay attention to her.

Luo Luo then grabbed a corner of her father's clothes with two little hands and started playing with it. She didn't seem to want to disturb her father, but some small movements still exposed her little thoughts - she saw Luo Luo's little butt swaying gently like a pendulum clock, hitting her father in a slight way.

"Dad is not available to play with you now, what's wrong?" Yang Yan had no choice but to free up his hand and gently rub the girl's head with the back of his hand.

"Um..." Luo Luo pouted her little mouth, wanted to complain but didn't know where to start, so she could only make a muffled hum unhappily.

However, when she turned around and looked for Grandma Li and wanted to point it to her father, the little girl found that Grandma Li was there, holding a tissue to wipe her tears!

Huh?

The little girl blinked her big eyes in confusion.

Why do you cry?

Luoluo suddenly forgot what she was going to say to her father just now. She grabbed the corner of her father's clothes with one hand, and slightly raised the other hand, without lifting it up, and stood there blankly watching Grandma Li who was crying a little pitiful.

Yang Yan followed her daughter's gaze and thought she was caring for Grandma Li, who was crying. Yang Yan hugged her daughter's little body lovingly, but because she was still in a cold state, Yang Yan did not kiss the little girl's little face.

"Aunt Li, don't worry, aren't we trying our best to help you catch these scammers and help you recover the money as much as possible!" Xia Yu comforted.

Just now, she was asking Aunt Li Qiongzhen about the police station’s arrangements. Obviously, the station only agreed to help investigate the account involved, but the action was much slower than Xia Yu’s side, and she had not even sent someone to the door for further understanding.

Of course, this is also related to the insufficient police force of the Shaping Street Police Station. Such a fraud case has a long investigation period and is not easy to solve. It is normal for the police to not keep a close eye on things like life-related matters. It is normal for them to move slowly.

"I just checked the phone number I called Aunt Li, just as I thought, not a real number! They should use Voip equipment to change the number, and then conduct the Overseas Chinese Federation through online voice, so that they can use disguised numbers to talk to Aunt Li's landline." Yang Yan also spoke to comfort Aunt Li.

However, Xia Yu couldn't understand what he said about technical aspects, let alone Aunt Li.

"So there is a way to bypass this disguise and track down their whereabouts?" Xia Yu asked directly.

Yang Yan was about to speak, but suddenly felt his nose itchy. He couldn't help but raise his head, and then turned to sneeze. Seeing this, Xia Yu quickly sucked a few tissues next to him and handed them to him with a worried look on his face.

"It's okay, it's okay!" Yang Yan took a tissue and blew his nose, and then continued to smile and said, "It can't be said to be bypassing the disguise. What I want to do now is to intercept their data packets and analyze that they are using the voip service secretly developed by the operator. This is generally illegal, but there are always some people who take risks."

"As long as we can find which operator it is, I can enter their servers from the network and find out the network IP address for the fraudulent phone call! These guys can buy Aunt Li's personal information and use some voip technical means. They are indeed a little capable, but I don't believe they still have such strong anti-reconnaissance capabilities and tamper with IP addresses that are almost impossible for anyone to find!"

Xia Yu and Aunt Li both looked at Yang Yan with a blank look on their faces, and they couldn't understand what he was saying at all. However, Yang Yan's confident expression still gave them a lot of confidence.

"How can you find them?" Xia Yu asked.

"This is a passive process. We have to wait until these people call us before I can intercept their data packets through my signal converter equipment!" Yang Yan pointed to the things he placed on the table and said to Xia Yu.

In fact, Yang Yan has already lost a lot of technical details. For example, the traditional telephone line modulates the computer's digital signal into an analog line number through adsl, and spreads it through the telephone line. Yang Yan in turn, mediates the analog line number into a digital signal, so that he can use the computer to analyze the data transmitted inside!

Of course, the equipment that Yang Yan himself researched and assembled is a bit complicated. It can perform one-way input and two-way output, which can ensure the continuity and quality of the original telephone call, and can also complete the copying of data.

"So we can catch them just by waiting for them to call, right?" Xia Yu still couldn't understand, so he had to confirm with Yang Yan again and again.

Yang Yan smiled, pointed his finger at the phone, signal equipment, and his computer, and said, "That's right, they called over, I intercepted the data, analyzed it, found out their IP address, and then I have a way to initially locate them!"

Just like Yang Yan checked the location of those human traffickers before!

Xia Yu nodded half-understanding this time. She clenched her fists confidently and said to Aunt Li: "That's good, Aunt Li, let's wait patiently for their phone call."

"But remember not to alert the enemy, because it will take time for us to track down their addresses. If they notice it and move out of there directly, it will be difficult for us to find them again!" Yang Yan reminded.

Xia Yu patted his thighs and said with a sudden realization: "Yes, Aunt Li, I will help you make up the clichés about how to deal with these fraudsters at that time. You pretend that you haven't recognized them as liars yet, and just use the excuse I gave you to tell them to ask them to wait for you for a few more days, and then show an attitude of being very interested in that physical examination card..."
