For the current trajectory tracking, Mu Yuan does not plan to use the time regression charm for the time being.

Even if it is not difficult for Mu Yuan to pay for the chivalrous value required to buy the time regression charm now, Mu Yuan has more places to use the chivalrous value, so if he can save it, he will save it!

In fact, if you start purely from the benefit, in fact, it is better for Mu Yuan to use the time rewind charm directly, and the time saved may be able to earn more chivalrous value.

In the days when he first entered the public security team, Mu Yuan must have done so.

But now Mu Yuan has more ideas.

He hoped that through his own reconnaissance ideas, he would be able to sum up some practical techniques and tactics that could be used by other police officers and that could be popularized on a large scale throughout the province and even throughout the country.

After all, no matter how powerful a person is, how many cases can he solve every day? Not to mention the whole country, just the cases cracked every day in the whole province can easily crush him.

Therefore, from the perspective of cracking down on illegal crimes, Mu Yuan prefers to use conventional means to solve cases.

Later, if you can't solve this problem by combining other methods, it's not too late to use time rewind.

Viewing monitoring may seem like a simple thing, but that's just the most basic application, and it's definitely a technical task.

Whether it is combined with the analysis of the spatio-temporal dimension, or combined with factors such as human geography, or even combined with the knowledge of criminal psychology, it is worth in-depth discussion.

From this point of view, this is properly an interdisciplinary discipline.

In terms of technology, Mu Yuan is undoubtedly a big presence in this industry.

Maybe there is nothing abnormal in the picture of a certain monitoring point, but if you look at multiple monitoring points together, you can see some clues.

Even by comparing the images at different points in time, you can occasionally get some detailed information.

However, the process is undoubtedly very long and very draining.

Fortunately, Mu Yuan is not in a hurry for this time now.

As time passed, more and more information was recorded on the blank piece of paper in front of Mu Yuan.

......

The next morning, the Jinchuan District Bureau's Criminal Major Case Research and Judgment Office.

Team Wan sat on a chair: "Team Mu, everyone, let's first summarize the information we have. ”

"This is the basic information of the four people we found. ”

"This first one, named Li Xi, female, from Southeast Province, 35 years old, returnee doctor. Since last year, he has been working in Xihua Chaoyang Biotechnology Co., Ltd. ”

"The second one is Feng De, male, from Dameng Province. 41 years old, university degree. I used to work for a law firm called Boan, and the employment information behind it is not clear. ”

"The third person, Du Lin, female, from Gui Province, 36 years old, has a university degree. The specific employment information is not available. And this person is the woman we locked down earlier who appeared near the scene of Hu Tian's fall into the river. ”

"The fourth person, Wang Feng, male, from Hei Province, 32 years old, has a high school degree. He has a record of engaging in security business. However, the current employment information is also unclear. ”

"Based on our investigation over the past day and the cooperation with the public security organs in the places where these people are registered, we have found out the following situation. ”

"Except for Li Xi, the other three have only recently appeared in Xihua City. And before that, Fonte and Doolin had been peers, and more than once. Wang Feng also has a record of traveling with Feng De, but only once. Li Xi has nothing to do with these three people, at least from the information we have found, there is no relationship. ”

"And the three of Feng De came to Xihua City this time, they came from different cities, and the time was almost concentrated in one or two days, so they should have been invited in advance. Through our inspection of the call information of the three people, we found that there was no call record between the three of them. Even, the few calling cards we found associated with them have very few calls in the past ten days. It is almost certain that all three of them have calling cards that do not belong to their real name information. From this, it can also be seen that they must have an ulterior motive when they went to Xihua City. ”

"As for Li Xi, we have checked almost all the information we can check, and she has no intersection with the other three. ”

Speaking of this, the Wan Brigade paused and looked at Mu Yuan.

Mu Yuan said with a serious expression: "I carefully checked the relevant surveillance video yesterday. Using Hu Tian's hot pot restaurant as a base, I pushed back a few hours, and I saw their movements many times from the surveillance video in the city. I just heard the call information from the Wan team, I recalled it carefully, there were at least two surveillances, and I saw Feng De making a call. We can use this to investigate and locate the phone number used by Fengde in Xihua City. As for this, the phone numbers of the other two people can be found, and then the contact information of the four people can be figured out, and at the same time, their recent activities in Xihua City can be ascertained. ”

"This is an important clue!" said the Wan team, "where is the specific location?"

"Guanglin Street Entrance. Mu Yuan said.

Wan Brigade immediately said: "Wang Ming, you take this information and go to the operator to check." ”

"No problem!" Wang Ming immediately responded, got up and left the research room.

Then there was a brief silence in the room.

Wan Brigade said: "Everyone, these four people, I think it's a little strange. How did a doctor, who had nothing to do with the other three, come together? ”

Mu Yuan nodded and said, "This is exactly what I suspected. However, I think that among these four people, the best entry point may be Li Xi. ”

"Why?" many people were puzzled.

Mu Yuan said: "It's very simple! You think, since these four people have gathered in Xihua City, it means that what they want to do is related to some people or certain things in Xihua City." Among the four of them, only Li Xi stayed in Xihua City for the longest time. In this way, we can make a bold inference that the three of Fengde went to Xihua City either at the invitation of Li Xi or ...... It's that the four of them have already planned it. ”

"Then why can't it be that after the three of Feng De arrived in Xihua City, they contacted Li Xi?"

"The relationship between the four of them from the surveillance data we have so far does not look like they are new acquaintances. Moreover, even if it is true that the three of Fengde only met Li Xi after they arrived in Xihua City, then this matter must be inseparable from Li Xi. Mu Yuan said.

No one argues with this.

Mu Yuan suddenly asked, "Team Wan, have you investigated the details of Li Xi?"

"I checked it! The specific information is here. The Wan Brigade handed over a copy of the information.

Mu Yuan took it and quickly browsed it, and the information included Li Xi's situation in the company, her place of residence, and even some of her activities in Xihua City.

All of this is in order, and there is nothing abnormal to see.

If there must be anything suspicious, it's that she's not married.

But isn't it normal for a 35-year-old unmarried woman to be in a big city nowadays? Not to mention that this is still a female doctor.

However, when Mu Yuan finished reading the information, he raised his head and said, "Wan Da Team, don't you think this Li Xi is very strange?"

"Strange?" said after a moment's thought, "There's nothing strange about it." ”

"She is in Xihua City, almost a two-point and one-line life. Mu Yuan said, "Wan Da Team, you immediately let people get to know each other from the side to see how Li Xi gets along with his colleagues in the company." ”

The Wan Brigade immediately responded, and then called two scouts to work on this matter.

Mu Yuan continued: "Also, in the information we found, the three of Feng De did not have a record of staying in a hotel in Xihua City. This shows that they have a foothold in Xihua City. But they had obviously just arrived in Xihua City, so where did they come from? I think this must have been arranged by Li Xi for them in advance, and it was not a hotel that was arranged, but a place to rent. ”

Wan Da Da frowned suddenly, and said, "In this case, it will be a little difficult to find the foothold of these three people." Although the management of the rental sector in our city has been further strengthened in recent years, there are definitely rental houses that are free from supervision. ”

Mu Yuan said: "Don't be in a hurry to find a place to stay, we can wait for the mobile phone numbers used by the three of them to find out before we do this." Now the focus is still on Li Xi. ”

"That's okay!" said the Wan Brigade seriously, "I'm mainly worried about when the three of Fengde will leave Xihua City, which will be very detrimental to our investigation. ”

......

Mu Yuan's request was implemented smoothly, and he personally led the team to monitor and track Li Xi.

According to the information they have so far, Li Xi has been at work for the past few days, and there is no phenomenon of being late or leaving early-just like she has been doing for more than a year.

Through the police of Jinchuan District Criminal University to his company to secretly investigate, it was learned that Li Xi was mainly engaged in research and development work in the company.

In this regard, it is unlikely that the police will know too many details about the work. However, there is one thing they have learned: Li Xi has not had dinner with any other colleagues since he went to work, although he looks kind, but he gives people a feeling of rejection from thousands of miles away.

That's where the anomaly lies.

People are social animals, if Li Xi originally had his own life circle in Xihua City, then it is understandable to work in the company but not participate in the company's dinner activities.

But Li Xi doesn't have any acquaintances in Xihua City!

She is neither from her hometown in Xihua City, nor from the university she studied in Xihua City, and even when she came to Xihua City more than a year ago, it was the first time in her life.

On the other hand, a person who has never had dinner with his colleagues immediately accompanied Feng De and the other three to have a hot pot meal after they came to Xihua City, which is very abnormal.

At the same time, this also shows that Li Xi and Feng De have a great relationship.

Therefore, as long as they keep an eye on Li Xi, they will definitely show their feet.

"Mu team, what can we see when we sit here?" Sitting in a Citroen C5 car, Li Ming said helplessly, "Why don't you ...... Shall I touch it in and see?"

Mu Yuan smiled and said, "If the other party is just an employee on the administrative class, you can still see it when you go in." But the other party is a staff member in the company who is engaged in R&D, and you can go in if you say you can go in? Unless you identify yourself, but that will be exposed. ”

"Then we're just going to have to wait?"

Mu Yuan glanced at him and smiled inwardly: You can only wait, I'm not.

But he couldn't say this, so he said quietly: "Otherwise, what else can you do?"

"Okay!"

As she spoke, a woman walked out of the gate of the building not far away.

She is wearing a floral dress, although she is not beautiful, but she also has an intellectual beauty.

As the saying goes, there is poetry and books in the belly, which is roughly the case.

Li Ming's eyes suddenly lit up, and he hurriedly said, "Team Mu, look...... Isn't she. ”

In fact, without Li Ming's greeting, Mu Yuan's eyes had already fallen on the other party, and said, "It's her!"

"Keep up?" Li Ming said.

"Wait!"

This woman is Li Xi!

I saw her walk quickly to the side of the street, stretched out her hand to stop a taxi, and quickly got in.

Mu Yuan picked up the walkie-talkie next to him and said, "People got into the West ATX380 taxi and kept an eye on it." ”

"Understood!

The person who answered was the scouts who stayed on the team, and they were responsible for assisting Mu Yuan in tracking through the surveillance camera - although Mu Yuan didn't need assistance, who made the Wan team not very reassured? He was afraid that if he lost it, he would delay the fighter.

When the taxi was about to reach the street, Mu Yuanfang slowly started the car and followed in that direction.

The taxi in front of him must not have realized that someone was following behind, and Li Xi couldn't just take a taxi and let someone else drive around the city, but in twenty minutes, the taxi stopped outside a café.

After seeing Li Xi get out of the taxi and enter the café, Mu Yuan parked the car on the side of the road.

"Li Ming, you go find a parking space and park the car. I'll go check it out first. ”

Li Ming didn't hesitate, and directly nodded in agreement.

After all, the tracking and monitoring ability of the Mu team is obvious to all in the city's public security organs.

When Mu Yuan's figure disappeared at the door of the café, Li Ming drove to find a parking space.

Mu Yuan didn't look for Li Xi's trace in the café, but found a booth and sat down.

What do you need him to do? Xiaomao can handle it, and he can do it better than himself.

Whether it is monitoring, surveillance, or even installing a miniature camera, Xiaomao is more competent than him for related work.

......

In the other corner of the café, three people were sitting leisurely.

They were particular about the location they chose, except for one side next to the other booths, the other three sides were empty. And the position where one of them is sitting is just right to see if there are people coming in and out of the booth next to each other.

And now, there is no one in the booth next to it.

So, they are a safe place, and they don't have to worry about being overheard – and of course, they can't make a loud noise.

The group didn't sit for long before they saw a woman in a floral dress approaching.

She walked straight to the side of the booth and sat down, took a sip of the warm coffee on the table, and asked with a smile, "How long have you been here?"

"Just arrived for a while. The older man said, "We've seen it around, and it's safe." ”

"Didn't you also say that it was safe last time? There are so many hot pot restaurants in Xihua City, choose an ordinary hot pot restaurant, and no one will notice. ”

"Hehe, it was just an accident. The man smirked, "And now the problem is solved." ”

"Are you ready to prepare?" Li Xi suddenly asked.

"Of course, I wouldn't have asked you to meet. The other woman said very indifferently, "But on your side, have you completely figured it out? We only have one chance, and if we miss it, we will fail." ”

Another younger man, with a determined glint in his eyes, said in a low voice, "This is a big deal! We can each share at least ten million." ”

Li Xi glanced at the other party and said, "I said, I want to take fifty percent." ”

"Even if you have fifty percent, I can still get ten million. The young man said with some arrogance.

Li Xi paused, and then said, "I've completely figured it out here." The day after tomorrow is the company's annual team building activity, in which the young people in the laboratory participate. The team leader and deputy team leader of the project team are older, and they will stay in the laboratory. According to the company's policy, there must be three people present in the lab at the same time, so I would ask to stay. Because I never go to company parties, no one suspects anything. The rest is up to you, and I told you about it last time. ”

"It's easy! Isn't it just looking for something, it's easy. The young man said.

The older man asked, "Are you sure they won't ask you to leave the lab when they leave the lab?"

Li Xi smiled slightly, and said quite confidently: "I have also stayed in the company for more than a year, so I won't make people so distrustful." What's more, I'll let you know when the time is right. At a critical point in the experiment, it is not said that it can be stopped. ”

"Okay! In that case, that's it. The older man said, "When you get your things, we will wait for you not far from your company and take you directly to the airport." ”

"I hope you don't forget your promises. Li Xi said with a serious face.

The older man smiled and said, "Definitely not!" I have already contacted the previous family, as long as you are sure to take the things out of the company, the first account will be credited to your account as soon as possible. The balance will be paid to you after the delivery is made outside the airport. ”

Li Xi nodded, took another sip of coffee, and got up and walked out.

When Li Xi left, the young man's face turned dark and said, "Brother De, look at her virtue! Do you really think that we won't be able to play this matter without her?"

The older man grinned and said, "If it weren't for her, we wouldn't have been able to get our hands on things so easily." I know you have an opinion on this share, but if you think about it carefully, Li Xi has spent more than a year on this matter, and she has taken a lot more risks than us in this matter, and it is normal to take the lion's share. ”
