Chapter 939: Difficulties abound!

After hanging up the phone, Xie Chenglong was very proud.

Li Mu and Wei Lan put on a good show without a script, but with great understanding and understanding, which made Xie Chenglong feel extremely real.

Even if Xie Chenglong had more criminal experience, this was the first time he had kidnapped him. Moreover, he asked for hundreds of millions of ransoms as soon as he opened his mouth. Such a large amount was completely beyond his ability to control, so that the entire situation was out of control. He didn't notice it at all.

Many people have upper limits on their ability to control. In the shopping mall, some entrepreneurs can plan perfectly if they are given one million, and every penny can be spent wisely. When given ten million, they will The reason for the chaos is that he is not strong enough to control the overall situation of 10 million, so under the leadership of such a person, the company basically cannot survive the B round;

In the military, there are many officers and generals who lead thousands of troops to make detours and lure the enemy deep. They are very good and skillful in fighting. But if they are really allowed to command the army and plan how to coordinate infantry and artillery, attack and encircle, and encircle and reinforce points, they will The reason is that the upper limit of his ability is suitable for leading an army of several thousand people. If there are more, he will lose control.

Li Mu, who has no criminal experience, has no advantage in crime itself compared to Xie Chenglong, who is experienced in crime, but in terms of controlling the overall situation, he is countless times better than Xie Chenglong, and even the momentum of his speech is completely different. Press him.

It is precisely because Li Mu controlled the rhythm very well, and Wei Lan is really smart to the extreme. He followed Li Mu's rhythm and said the two words he was holding back until the end. It was just perfect.

Xie Chenglong didn't know that Li Mu had already learned about the person behind the kidnapping of Wei Lan. He hung up Li Mu and took out the battery of Wei Lan's mobile phone. He had heard about signal positioning. It is said that as long as the mobile phone lasts Within a few minutes of turning on the phone, the police could calculate the approximate location of the phone through the signal strength of each base station. Although he didn't know whether Li Mu would call the police after hanging up the phone, he didn't dare to take this risk.

After taking off the battery of his mobile phone and putting it in his pocket, Xie Chenglong said to Wei Lan in a calm tone: "You're cooperating well. I'll let you have another call with him at 12 noon tomorrow. No one will disturb you during this time." You, but you should also be honest and don't play any tricks."

Wei Lan knew that with Li Mu's wisdom, he must have received the message he conveyed, so his heart was as clear as the moon, and he nodded to Xie Chenglong with excitement.

Xie Chenglong misunderstood Wei Lan's excitement and was even laughing in his heart. This woman is really stupid. Do you really think that Li Mu can survive if he agrees to give her money? Don't be naive, you have seen my face, no matter whether you can get the money or not, you will not survive.

However, it is also a good thing for her to continue to have some hope of survival. As long as she feels that she has a chance to survive, she will actively cooperate to get the money.

Thinking of this, Xie Chenglong felt very comfortable. He opened the door and went out, saying to the two men guarding the door: "Keep a good watch for me, but without my permission, no one of you is allowed to go in and disturb me. Do you understand?"

Now Wei Lan is a golden Bodhisattva worth over 100 million. Xie Chenglong will never allow anyone under his command, not even Song Zhilei, to have any wrong thoughts about her before he gets the money.

The two subordinates also knew Xie Chenglong's uncompromising and ruthless character, and nodded quickly: "Brother Six, don't worry, we will definitely not go in and disturb..."

Xie Chenglong nodded with satisfaction: "After this is done, brothers will enjoy the spicy food. I will take you to the south. Then you can find any woman you like!"

Li Mu hung up the phone and did not call the police immediately. He knew in his heart that although the police were necessary, they must not be called through normal channels.

When calling the police through normal channels, the people below know first, and then convey it to the top step by step. The way the information is conveyed is like an inverted pyramid. In this way, the information spreads too much and you cannot control it at all, in case the robbers know about it. , will definitely increase the danger for Wei Lan.

What Li Mu thinks is that now that he knows that the mastermind behind the scenes is Song Zhilei, he has 48 hours to find Song Zhilei. If he finds him, he can find Wei Lan.

As for how to find Song Zhilei in the vast sea of people, he had to rely on the public security department to handle special cases. Li Mu knew that the capabilities of the state machine were far beyond his imagination, so he had to rely on the government at this time.

Only then did Li Mu have time to check the text messages on another mobile phone. Song Liang sent three messages to Li Mu, namely: "I'll be there soon!", "What's the specific situation?", "What do you need me to do now?"

Chen Ze sent two replies to Li Mu: "Damn it! I'll be there right away!", "I called the Gu Bureau of the Municipal Bureau, and he's already on his way to Taobao!"

When Li Mu saw that Chen Ze had found the top leader of the municipal bureau, he felt a lot relieved. Chen Ze was worthy of being a son of an official. He knew that such matters should be dealt with from top to bottom. He first found the director of the municipal bureau to inform him of the situation. , and then let him carefully select elites with strong abilities and high quality to jointly solve the case, and the case will naturally be much easier to handle!

Leader Lei and Senior Brother Liu had been listening nearby, and naturally they could hear what was going on. They hurriedly asked about the specific situation, and Li Mu gave them an overview. After hearing this, the two of them exclaimed in surprise about Wei Lan's experience, and also They all sighed: "Wei Lan is such a wise woman, she revealed the most critical clue in just two sentences!"

Li Mu said: "The next step is to see how to save people."

Senior Brother Liu asked him: "What are your plans?"

Li Mu said: "Ask the Yanjing Municipal Bureau for help, but you must first find the senior leaders, who will directly assign elite personnel to solve this case."

Ten minutes later, Song Liang arrived first.

As soon as he entered the door, Song Liang couldn't wait to ask Li Mu: "What's going on?! Has the kidnapper contacted you?"

Li Mu nodded, and just as he was about to introduce the situation, Bureau Gu, who lives in the city, also arrived.

As the head of the city bureau, Bureau Gu was really uneasy coming here.

To be honest, the last thing he wants to do in Yanjing is to deal with Li Mu, because he is a police officer. No matter how awesome Li Mu is, it has nothing to do with him, but if anything goes wrong, he will take the blame.

It had been a while since I had had any relationship involvement with Li Mu. Unexpectedly, I had fallen asleep today. A call from Chen Ze made my nervous heart beat wildly.

Wei Lan was kidnapped. Although she didn't know much about this woman, she had heard about her. She used to be a well-known real estate developer in Shanghai, and now she is Li Mu and Chen Ze's partner in Wanying Real Estate.

Li Mu was difficult enough to communicate with, and Chen Ze was involved. The two of them together put great pressure on him.

The kidnapping case is a very serious criminal case, and it is also a case that can easily cause bad social impact. With these two young gods involved, Gu Jianghe is really anxious.

As soon as Bureau Gu arrived, he hurriedly asked what happened. Li Mu called Chen Ze and heard that he would be there in five minutes, so he said to Bureau Gu and Song Liang: "Everyone, please wait for a moment, Old Chen." Here I am, let me introduce the situation to you."

Director Gu felt very uneasy and couldn't help but say: "Mr. Li, do you need me to arrange the troops in advance and get everyone in the city bureau to move?"

Li Mu said: "We can't let the information spread too much now. Gu Bureau, please call directly and ask a few elites in criminal investigation to come here in plain clothes. I'm afraid that someone among the kidnappers is secretly watching me. If you find me going at this time, The city bureau will definitely give them a great sense of urgency.”

Song Liang, who is experienced in society, also nodded and said: "It's best for Li Mu to stay here and not move. If possible, I would like to ask you to organize a task force in person, and the headquarters will be here."

Director Gu thought the same thing. If the kidnapper really followed Li Mu's every move, then he would naturally not be able to have any direct interaction with the police. Li Mu's place was not far from the city bureau. For example, he could just set up a headquarters here.

Therefore, Director Gu immediately called several very experienced criminal investigation veterans in the municipal bureau system. Half an hour later, all of these people rushed to Li Mu's office with their most trusted subordinates to discuss the case.

Criminal investigation experts from the Municipal Bureau proposed several parallel plans. One was to immediately search for the first scene of the crime and find clues from the crime scene. The other was to use mobile phone positioning to find Song Zhilei's whereabouts.

The city bureau urgently assembled a team of criminal police officers in plain clothes and began to investigate from the place where Wei Lan last left, which is Wanying Real Estate. At the same time, mobile phone operators also began to actively cooperate.

The public security organs have the right to require operators to cooperate in obtaining relevant information of all mobile phone numbers. Gu Jianghe took this matter very seriously. He called the Yanjing managers of the two major operators in the middle of the night and requested that senior technicians be sent to Taobao immediately to do their best. Cooperate with the police to solve the case.

At around one o'clock in the morning, Taobao's sales had just exceeded 300 million yuan. The Yanjing managers of the two major operators rushed to Taobao with several nervous operator technicians, computers and other equipment, and immediately reported to Taobao upon arrival. Gu Jianghe stated that he would do his best to help the city bureau solve the case.

Gu Jianghe immediately issued the first order: locate the location of Wei Lan's mobile phone.

After the mobile operator's engineering technicians worked on their backend system for a while, they said with an apologetic look: "The other party's phone is no longer online, and we can't locate her specific location."

Li Mu frowned: "What is your base station positioning logic?"

The technician said: "Mr. Li, the base station positioning logic is to contact the mobile phone through multiple base stations, and then use the signal difference between the multiple base stations and the mobile phone to determine the approximate location of the mobile phone, such as one kilometer away from point A and one kilometer away from point B. Point C is 1,500 meters away and is 1,800 meters away from point C. Draw a circle with the distance from the three base stations as the radius. The area where the three circles overlap is the approximate location of the mobile phone. This positioning method is not accurate enough and has an approximate error. About one or two hundred meters.”

Li Mu said: "Then take a look at the base station records of the last time Weilan's phone connected to the network. Using your method, can you deduce the specific location?"

The technician shook his head and said: "Mr. Li, our base station will not actively record relevant information when users access the network, so there is no specific base station record in our backend, only the record of the user's access time."

Li Mu was very surprised: "No record? Doesn't your base station record by default the information of the equipment connected to the network at this base station?"

The technician said awkwardly: "To be honest, Mr. Li, you are in the Internet business, and your background processing is not much different from ours. You know, a piece of equipment is in an urban area, and with his daily life, he has to do it frequently every day." Switching base stations dozens of times, or even more, if the base station has to record every time it is connected to the base station, the amount of data written is really huge, and it is difficult for our database to provide such support... "

After finishing speaking, the technician explained: "Only in one case will our base station actively record user data."

Li Mu asked: "What's going on?"

"Roaming..." The embarrassment on the technician's face became even more obvious, and he said: "The reason why the user's base station switching within the local range is not recorded is that the amount of data written is too large, and it is also due to cost considerations. , but once the user goes to a different place, the call will incur roaming charges, so in the roaming state, the base station will record his relevant information to collect the user's roaming charges... "

Chen Ze immediately exploded: "Holy shit! Your operators are so screwed up! If local users don't incur roaming charges, you won't record them. If roaming charges are incurred, you won't record them all at once?"

"this… "

The technicians' faces turned red. This is indeed the case. Enterprises also serve profits and do not want to blindly store a large number of records that cannot generate revenue to increase costs and burdens.

Li Mu understood in his heart that mobile operators have hundreds of millions of users across the country. If the information about each user switching base stations back and forth every day would be recorded and written into the database, the amount of data generated every day would be so huge that it would be terrifying. Without profit-driven operation, Business operators will naturally not invest so much to retain this meaningless data, and the greater the amount of data written, the greater the impact and test on system stability, so they only retain roaming data, which is in line with business and technical logic. .

So, Li Mu said at this time: "Let's not talk about it for now. Let me ask you, since there was no base station record here the last time the mobile phone was connected to the network, that means that Wei Lan's mobile phone was still in Yanjing City at that time. Within the jurisdiction, right?”

The technician nodded: "It was like this the last time I connected to the network, but it's turned off now, so I can't guarantee whether it's still within the city's jurisdiction."

Li Mu asked again: "Then if the other party's phone is turned on and accesses the network again, how long will it take for you to locate the specific location?"

The technician said: "It will take at least two minutes."

Li Mu was also about to explode: "Two more minutes? Why?"

The technician had no choice but to explain: "When we first connected to the network, we could first get the information about the base station that was connected by default. The positioning method just mentioned requires at least three base stations to connect to the mobile phone for three-point positioning. Only one base station was determined. In this case, if it is an urban area, it may only be able to locate a one-kilometer radius. If it is a suburb, it may be a two-kilometer radius or even larger area. It is too inaccurate... "

Li Mu asked him: "So you need more than two minutes to determine the location only after confirming the information of the first base station to be connected by default, and then allowing at least two nearby base stations to connect to the mobile phone?"

"Yes." The technician nodded and said, "The actual situation will be more complicated. The mobile phone can only connect to one signal source at a time, which is one base station. Therefore, in order to allow the mobile phone to connect to other base stations, we must first weaken or even shut down Stop the signal of the first base station, then enhance the signal of other base stations, let the mobile phone capture this signal and then connect. After confirming the information of the second base station, shut down this base station and strengthen the signal of the third base station. Let the mobile phone connect. Only after the mobile phone successfully connects to three base stations can we infer the specific location. This is equivalent to letting the three base stations successfully communicate with each other's mobile phone one by one, so two minutes is an optimistic estimate... "

Li Mu was dumbfounded.

Damn, I’ve seen criminal investigation clips in movies before. It takes time for the police to locate the suspect, and many times the suspect has just the right amount of time. Just when the police are about to locate him, he hangs up the phone and calls himself I used to think that these were just exaggerated interpretations of film and television works, but I didn’t expect them to be so troublesome!

Li Mu asked again: "If the other party's call time does not meet your needs at 12 o'clock tomorrow, you still won't be able to locate a specific location, right?"

The other party nodded: "We can locate a rough radius, but this radius may be very large. If it is in the suburbs and the signal base stations are not dense enough, then the range will be even larger..."

Li Mu smacked his lips and said, "Then check Song Zhilei's cell phone number now and see what's going on with his cell phone!"

Nowadays, most mobile phone numbers do not have a real-name system. However, the mobile phone number commonly used by Song Zhilei is a leopard number with four 8s. This number was obtained from the mobile operator through finding connections, so there is real-name authentication, and the technical personnel from the operator first Immediately began to thoroughly investigate the roaming situation of this mobile phone number.

However, the results of the investigation were particularly disappointing: "Mr. Li, the last time this mobile phone was connected to the Internet was five days ago. The location was local in Shanghai, and then the audio was lost. It should be that the device has been shut down, and it has not been heard until now. Turn it on again."

"Check if there are any other mobile phone numbers in Song Zhilei's name?"

"One of them also shut down five days ago!"

"Where's his family?"

"His wife was found, and her cell phone was also turned off five days ago!"

Difficulties abounded, and Li Mu suddenly felt nervous and desperate.

I know it was Song Zhilei who did it, but I can’t find Song Zhilei. What should I do? Time is running out, and the longer it takes, the more dangerous Wei Lan will be.

The criminal investigation team of the city bureau has begun to make arrangements starting from Wanying Real Estate in plain clothes. At the moment, Li Mu only has two people to rely on:

First, the criminal investigation team should find the first scene as soon as possible and follow the clues to find valuable clues;

Second, when the kidnapper calls to confirm at 12 noon tomorrow, let the operator's technicians conduct base station positioning, hoping to locate the other party's location!
