Huang Jiu was born in a family of intellectuals, his father Huang Tiancai was a professor of economics at a university, and his mother was a special teacher in a provincial key high school before she died of cancer.

From childhood to adulthood, she was the daughter of someone else's family in the mouth of her neighbors, she was admitted to university at the age of 15, graduated from graduate school at the age of 22, and was already a backbone member of the Economic Investigation Brigade of the Hedao Public Security Bureau at the age of 25.

Well-behaved and intelligent have always been her labels.

But at this time, Huang Jiu had just experienced the most unbelievable scene in his life, and the newly bought mobile phone in the morning turned into a card with a mouse pattern under her gaze.

A sharp cry went from the dantian to her throat, but because this incident was so weird, not only did she not make a sound, but she gasped.

Cold air entered Huang Jiu's lungs through his nose, and his brain cells seemed to sense a large amount of oxygen injection, and quickly began to become active.

"The theft of famous paintings!" The big case that was uploaded on social platforms appeared in front of Huang Jiu's eyes for the first time.

The precious oil painting mysteriously disappeared from the museum in the blink of an eye, and when she saw the video released by the French police, she also believed that the thief had tampered with the content of the video through unknown means, and argued with netizens who advocated superpower crimes on the Internet.

"This is not just a slap in the face, it just smashes my head!" For a moment, she even thought that the identity of the mouse might be the netizen who sprayed her on the Internet today.

"Why would a famous painting thief steal my phone? And I just bought it in the morning, so it can be said that there is not even a little useful information in it.

No, not many people know that I change my phone, and if I put aside my colleagues, is the mouse a clerk who sells mobile phones?

No, no, no, if you still need to steal mobile phones in this way while working in a mobile phone store, it would be too stupid. ”

Huang Jiu was confused, she didn't know that this incident was actually an accident for Bai Jin.

What she also didn't expect was that such an accident made the fates of the two people intersect for the first time.

The reason why excellent people are excellent is because no matter what kind of dilemma they encounter, they can adjust themselves in the fastest time. Less than half a minute later, Huang Jiu decided on the next countermeasure.

She borrowed her father Huang Tiancai's mobile phone, and Huang Tiancai already understood what was going on the moment he saw the card in Huang Jiu's hand.

Huang Jiu dialed a friend's number, and a familiar voice came from the other side of the phone.

"Hello, Uncle Huang."

"Hae-yeon, it's me."

There was a noticeable pause on the other end of the line.

"Honey, why did you call me from Uncle Huang's phone? I just thought your dad was checking the post, and he called me so late, if you want to ask me to go to the bar, I'm sorry, I'm on duty. ”

"I just know you're on duty before I look for you. My phone was stolen. ”

"Huh ? If your phone is stolen, you should go to the police station. Do you have any misunderstanding about my work, sister, I work in the technical reconnaissance brigade, and I sit in the office. I can't catch thieves. "Haiyan is 2 years older than Huang Jiu, and they are friends who grew up together.

If there was no Huang Jiu, Haiyan would also be the kind of daughter of someone else's family.

You don't need your parents to worry about it, you are at the top of every exam, you are beautiful, and you have a good personality.

The reason why it is less discussed is because Huang Jiu is too eye-catching, and they are too close to each other.

"It's not what you think, it's the kind of 'whoosh', like the 'Mona Lisa'."

Huang Jiu was a little incoherent in a hurry.

Hae-yeon understood in an instant.

Including what Huang Jiu has not yet spoken, the purpose of making this call.

"I know, you wait for me for ten minutes, and I'll get back to you." Hae-yeon put away her grinning expression and hung up the phone.

LBS base station positioning is based on the positioning method of the signal tower of the communication operator, and the longitude and latitude information of the mobile phone SIM card is obtained through the signal tower.

That is to say, unlike most film and television works, LBS positioning only needs the mobile phone to be turned on, and it can be located, and the accuracy of positioning depends on the distribution and coverage of the base station.

Just now, Haiyan had already retrieved the signal location of Huang Jiu's mobile phone through the server.

"I wonder if the big case that shocked the world will be solved because of this." Hae-yeon found that she was trembling slightly.

According to the location information, the rat is in Hedao City!

"But this place is a bit tricky." The advantage of LBS positioning is that it is fast, but after all, it relies on base station positioning, and in places where the signal is complex, there will occasionally be an error of more than 1 km. Hae-yeon muttered as she looked at the range of locations displayed on the computer.

Railway station.

Yes, Bai Jin's home is near the train station in Hedao City. I chose this place mainly because it was only a few minutes' walk to the company where I used to work. Thanks to Bai Jin's unintentional choice 5 years ago, he helped him escape the catastrophe.

Hedao Railway Station is located in the center of Hedao, surrounded by two super-large shopping malls and an underground discount shopping street, directly opposite the Hedao City long-distance bus station, surrounded by a large number of hotels and apartment buildings under the banner of hotels.

Because Hedao is a well-known tourist city in the country, tens of thousands of tourists come and go every day. Finding someone in such a place is like looking for a needle in a haystack.

Hae-yeon immediately reported the results of the investigation to her superiors and received orders for continuous monitoring. She stared at the location information on her computer screen, hesitant to track the GPS signal.

GPS positioning is more accurate than LBS positioning, but the disadvantage is that the positioning takes a long time, if the other party is looking at the mobile phone at this time, and finds that the GPS suddenly starts, it may startle the snake.

"The signal appeared at the train station, was it about to run? Or where did it come from? Hae-yeon muttered to herself as she opened the website to check the timetable for the nearest train arrival and departure station.

The dense number of trains means that at least thousands of people are hovering around the train station during this time of year.

If the positioning could be more accurate...... Hae-yeon's heart couldn't help but have such thoughts.

"Otherwise, take a gamble, it only takes ten seconds, and if the mouse doesn't find it within ten seconds, you can get accurate location information within ten meters."

Hae-yeon prayed and pressed the GPS tracking button.

Although it is not known which god Hae-yeon made a wish to, the god did not respond.

In a second, the phone's signal disappeared.

“FUCK！” Hae-yeon's fists slammed into the keyboard, and her eyes seemed to erupt into flames.

In such a short time, there is not enough time for GPS to search for satellites, which Haiyan also knows very well. Such a result means that because of her reckless actions, the rats may escape.

It's just that it's too late to regret it now, so Haiyan packed up her emotions and picked up the phone.

"How's it going, have you found anything?" Huang Jiu's eager voice came from the opposite side.

"Let's not talk about this for a while, let me ask you, is there anything in your phone that you can't let others see?" If you just listen to the voice, no one can relate to Hae-yeon's current expression.

"I didn't ...... Yes, right? Do selfies count? ”

"Miss...... I'm not talking about this kind of thing. But since you mentioned it, please go into more detail about the 'unsightly selfie'. ”

"No, I think what I'm saying and what you're thinking shouldn't be the same thing."

"I suggest that this kind of thing is better left to me, a professional, to judge."

"Instead of hurting my friend who has been single for 25 years, why not summarize the progress in the most concise language?"

Haiyan took a deep breath and said, "Mouse, in Hedao." ”
