Paranormal Investigation Notes

area?

This term made He Wei and Lu Qingliang look at each other.

Lu Ming continued: "Also, through the analysis of the scope of activities of Han Rui and Shen Xiaojuan, I also found that the two of them were outside their own area, relatively regularly, every once in a while - about 2 to 4 months In between, we will go to another big city that is far away.

We have enough reasons to suspect that that city is the center of a higher-level new sect.

If a certain area and the city where the seductress lives for a long time is regarded as a third-level center, then this large city far away should be a second-level center.

We can't be sure what the Soul Enchanter regularly goes to the second-level intermediate level for, but we can speculate that it is most likely to go to the higher-level center to pick up some consumables, receive some latest instructions, and conduct some training.Well, none of this actually matters, as long as we know that the Soul Educator will go to the secondary center regularly.

In this way, we can roughly outline the behavioral characteristics of the seducers: they usually move more frequently in a certain fixed area, frequently make short trips between different cities, and at longer intervals, they will go to a distant place. Big city once.

At this moment, the area where there are soul seducers can be determined by the area where the new sect is active.If we adopt the previous screening method and screen the active areas of the new faction, we may find something. "

Zhang Dingshan, He Wei, and Lu Qingliang thought for a moment and gradually understood Lu Ming's thoughts.

“Let’s see if you have any results after trying it!”

Zhang Dingshan made the decision immediately.

Soon after, data on the active areas of the new faction was gathered and displayed on the world map.

Places where the security department frequently cracked down on freshmen were marked in dark red, and then gradually became lighter until the color returned to normal.Lu Ming took a look and saw more than a dozen red gathering areas clearly appearing on the world map.

Among them, Dajiang City, where Hu Shan is located, is prominently listed.Although its color is not the reddest, it can still be ranked among the top.

After selecting the remaining six areas with the reddest colors, excluding the Dajiang City area, which also means that the new sect is the most active, has the most victims, and has the most seducers, Lu Ming said: "Let's start screening here."

The reason why Dajiang City was excluded was that Han Rui was captured by our own side in the Dajiang City area. The secret organization's layout in this area will almost certainly be adjusted to avoid being followed by our own side.This means that the data here is "contaminated" and no longer has the value of investigation.

Lu Qingliang immediately said: "I will contact the transportation department and collect traffic data."

He Wei said: "I will contact the supercomputing center to prepare computing power."

The total population of these six regions, or six urban agglomerations, is estimated to be over [-] million.It is impossible to filter out the traffic data of so many people without using a supercomputer.

The four people started working separately, and soon completed the data migration in a relatively concealed manner, and submitted the filtering conditions: "In the past five years, I have carried out frequent short trips within a 200-kilometer radius on a regular basis. Every time 2 to 4, well, let’s be loose, 2 to 6 months, for a long trip.”

Even with a supercomputer, it will take a certain amount of time to sift through such a huge database.This wait lasted three days.Three days later, the data was filtered and fed back.

In the conference room, Lu Ming turned on the projector, and 10,000+ dense lines appeared on the huge world map, connecting different cities.

Each line represents the activity trajectory of a person who meets the filtering conditions.

"After screening, a total of 176533 people met the criteria."

The total number was as high as 17!

Lu Ming was surprised, a little unexpected.

It is obvious that most of these people are ordinary people.What he didn't expect was that so many ordinary people met the screening criteria.In daily life, Lu Ming felt that he had never seen anyone take frequent short trips and then regular long trips.

It is obvious that so many people do not meet the verification conditions and can only be further screened.

Lu Ming thought for a moment and formulated a new filtering condition.

"Occupational background is non-company employees, non-government workers, non-public welfare organization members, etc."

Lu Ming believes that the reason why so many ordinary people travel so regularly is most likely because of official business.For personal reasons, it doesn’t mean that there aren’t any, but the number should be very small.

There are only a little over 17 people at the moment, so there is no need to overcalculate when filtering.A laptop sitting on the table will do the job.He Wei clicked a few times and entered the relevant filtering conditions. After filtering again, the results appeared quickly.

This time, most people were screened out.

Sure enough, just as Lu Ming expected, most of the people were there because of official business.

At this time, only about 1.2 people are eligible.

Lu Ming was almost certain that there must be seducers hiding among these 1.2 people.

Lu Qingliang said slowly: "If there are 1.2 people, it is possible to mobilize more manpower and verify one by one in reality."

Lu Ming shook his head decisively: "No. There is too much movement, and it is very likely to alert the secret organization. We must find some more screening conditions to filter out irrelevant people."

He Wei thought carefully: "If it is a seducer, the destination city for its long-distance journey should be fixed."

Lu Qingliang immediately said: "Not necessarily. Even if you are a seducer, you can actually travel to other cities. Or because of some family matters."

"However, it is impossible to stay in one city for a long time if you really want to travel. In short, the city that is a secondary center should be visited more often. In five years, it will be at least ten times. . Be prudent and calculate it as eight times. At the same time, the distance between the real secondary central city and the third-level center should be within a certain range, not too far."

Lu Ming nodded and agreed with this standard: "That's true. Then add another filtering condition: long-distance travel to a city at least eight times or more within five years. Also, target locations more than 1000 kilometers away from a certain area can be removed Relevance to the region.”

After screening, up to nine out of ten people were screened out.At this moment, there are only 1256 targets left.

More than 1000 people are still too many.But at this time, it seems that it is not that simple to find some more universal conditions to filter.Zhang Dingshan said slowly: "Those who stayed too long will be screened out, those who are traveling with us will be screened out, those who have clear itinerary records in the city will be screened out, those who are over 60 years old, or those who are in poor health will be screened out. "

The seducer works in secondary central cities.I still have business in my area, so I am unlikely to stay in a secondary central city for too long.

With such a clandestine operation, it is unlikely that the Seducer would have any companions, and it is unlikely that he would leave a clear record of his itinerary.At the same time, the so-called seduction task is both technical and physical work, so the elderly and infirm can be screened out.

However, these conditions did not screen out too many people, only about one-third of the people.

At this moment, there are 809 potential targets left.

Zhang Dingshan said decisively: "There are six regions in total, let's talk about them as individual regions. Let's talk about the Lantian City region first."

Blue Sky City and a dozen surrounding cities, large and small, combine to form a red gathering area.In this gathering area, there are a total of 160 people who meet the screening conditions.

"Based on the frequency of cases, there cannot be only one seducer in this area, there should be at least four or more. In this way, cities with less than four arrivals will be screened out."

At this moment, there are a total of 16 cities around the Blue Sky City area that may be secondary centers.Two cities contributed the largest number of arrivals, accounting for more than half, with a full 100 people.In the remaining eight cities, the number of arrivals ranged from 4 to 10 people.The last six cities only have one to three people.

These six cities have also been excluded, which means that 10 more people have been excluded.

There are still 150 people left in the Lantian City area.

At this point, it is almost impossible to rule it out.The four of them were facing the world map at this moment, each thinking silently.

After a long time, Zhang Dingshan said slowly: "I noticed that the number of people arriving in a city is highly positively correlated with the city's popularity."

Lu Ming was startled, and many thoughts immediately emerged in his mind.

The so-called city popularity is a comprehensive concept, covering all aspects of the city's tourism resources, economic strength, population, culture, etc.In short, the more famous a city is, the more popular it is.

In this case, it is almost inevitable that the number of people arriving in a city is highly positively correlated with the popularity of the city.

The reason is simple. After excluding non-official, non-medical and other necessary reasons for long-distance travel, for ordinary people, the only reasons for traveling thousands of miles to another city are tourism and visiting relatives and friends. Category.

Obviously, the more people a city has, the more people will come to the city to visit relatives and friends.The better a city’s tourism resources are, the more people will visit the city.Urban population and urban tourism resources are both important components of urban popularity indicators.

But another point that is obvious is that when a seducer comes to a secondary central city, he will not look at the popularity of the city.

As reflected in the data, the urban popularity of certain cities does not match the number of people arriving in the city.

Of course, under big data statistics, it is normal for slight deviations to occur.However, the long-term visits of at least four Soul Educators will contribute at least 32 travel data.Reflected in the data, it is a large deviation that cannot be explained by the normal fluctuation of the data.

"Yes, that's true. Let me make a statistical table first."

Lu Ming quickly made a comparison chart of the number of visitors and the city's popularity for the remaining 10 cities.After just one glance, several people saw something was wrong.

Except for Hualu City and Mei'an City, the trend of arrivals in the remaining eight cities is roughly consistent with the trend of city popularity.Only in these two cities, the number of arrivals is relatively large, which does not match the popularity of the cities.

"Two cities?"

Lu Qingliang frowned.He Wei immediately said: "There must be only one secondary central city. One of the two cities must be included due to statistical errors. The other city is our real target."

It is almost impossible to further distinguish which city is the real target and which city is just a statistical error.But at this moment of analysis, there is no need to distinguish anymore.

The reason is simple. The total number of arrivals in these two cities is only 40.The target range is small enough.Even if everyone sends a guard to follow them, it won't attract anyone's attention.

"It is very likely that the Soul Seducer is hiding among these 40 people." Zhang Dingshan said slowly: "In order to ensure that they are not discovered by the secret organization, the guards sent to follow these 40 people must be the best among the best."

But... no matter how elite the guards are, no matter how advanced the tracking technology is, who can guarantee that they will not be discovered?And once discovered, one can imagine what consequences our side will face.

Lu Qingliang looked slightly worried.Apart from him, Zhang Dingshan and He Wei were full of perseverance.Although Lu Ming felt a little uneasy, he finally suppressed the fear in his heart and nodded seriously.

In this case, this plan was passed and entered the implementation stage.

40 guards were secretly mobilized and secretly set off to different cities to begin tracking and surveillance missions.From now on, they will dig out all the secrets behind these 40 people as much as possible until they gain something.

From this moment on, Lu Ming felt as if there was a sword hanging over his head. No matter what he did, he always felt a little nervous.

Three days passed in this uneasiness.Three days later, a guard sent back a video recording.In the virtual conference room, Zhang Dingshan opened the video, and Lu Ming immediately saw a man of medium build, using the cover of a slope in the woods to pull off a funny-looking hat. A white paper hat was placed on his head.

A wave of hot blood rushed into Lu Ming's heart instantly. At this moment, his heart was beating crazily and he could not calm down no matter what.

"He is the seducer, you can't be wrong!"

He Wei jumped at the crime and immediately checked this person's information: "His name is Zhang Fu, and the city of arrival in the statistics is Mei'an City! Mei'an City is the real secondary central city of the secret organization!"

With this definite clue, the suspicion in Hualou City was immediately eliminated, which also meant that the suspicion of 26 people was eliminated.

Apart from Zhang Fu, the only remaining suspects are 13 others who arrived in Meian City.

After a few more days of tracking, another seducer was unearthed.However, the expected No. 4 and No. [-] seducers were not found after the last suspect was ruled out.
