When Han Siyan rushed into the task force, the pistol on her waist was pulled out, because there was a fierce exchange of fire in the task force room at this time. With the burst of pistol fire and the short burst of assault rifle fire, she almost had to roll first to find cover.

When she saw the situation clearly, her nose was almost crooked. It turned out that Kang Tian was playing a crossfire shootout game.

The high-end hardware audio equipment of the city bureau realistically restores the gunfire in the game, making people really think they are on the battlefield at first glance.

If it weren't for Kang Tian swearing on the phone that he had discovered the extremely important clues of the 616 case, Han Siyan would not have paid attention to this hacker master.

As a result, she hurried back to the bureau and saw Kang Tian playing games in full swing, so angry that she walked to Kang Tian's computer desk, stretched out her hand and pulled out the network cable, and the deafening gunfire all over the house finally stopped abruptly.

Kang Tian saw Han Siyan at this time, and he said with a hippie smile: "Yo, Captain Beauty, you're here so soon?。。。。 What are you doing with a gun?"

Han Siyan put the matching gun back into the holster with an expressionless face, clasped her hands in front of her chest, and asked coldly, "Officer Kang, didn't you say that you have an important case to tell me?"

Kang Tian didn't know that Han Siyan was on the verge of breaking out, and was still nagging Bibi there: "Of course there is an important case, how can I lie to your beautiful sister." But I'm a little hungry now, are you hungry? Why don't we find a place to have a late night snack and eat at the same time... Oops... It hurts, it hurts. You let go ... ”

Han Siyan, who couldn't bear it, grabbed Kang Tian's neck and pressed his face on the computer desk, gritted his teeth and spit out a word: "Say!"

"I said I said ... You let me go first. ”

Han Siyan let go of Kang Tian, he rubbed his neck, and muttered in his mouth: "Siyan, you are good at everything, if your temper can be smaller... Seeing that Han Siyan's beautiful eyes began to stare again, Kang Tian didn't dare to get scared anymore.

"Captain Han, I found the suspect's second mobile phone, do you think this information is important?"

"What? Did you really find it?"

"Of course. That's it, the number is 131。。。。。 ”

"Are you sure? Where's this phone?"

"Sure, sure, sure. But now that the phone has been turned off, it may be out of battery. But its final orientation is in the gardens of the Kate Building. ”

Han Siyan picked up the hand table on the table and ordered inside: "The personnel on duty of the 616 task force will come to the conference room to gather immediately, immediately!"

After Wu Zhihong and several other police officers on shift entered the conference room, Han Siyan motioned for Kang Tian to explain.

Kang Tian wandered on the podium of the conference room, hugged one hand, and stroked the grass-like bangs with his index finger with the other, coughed and said:

"We couldn't find any suspicious connection from the mobile phone commonly used by the suspect cleaning lady, including the two suspected missing security guards, right? ”

Kang Tian thought he was humorous, but unfortunately everyone in the conference room was expressionless - the performance failed.

"Ahem. Since we're assuming a second phone exists, why can't we find it?"

The simple answer is that the female worker hid the phone before the move, and anyone who is a little more cautious would do that. A policeman really couldn't stand Kang Tian's pretense, so he said a word.

"Bingou, you got it right. Kang Tian didn't notice the ridicule of others at all: "Then the second question is, if this group of people is cautious and will hide this mobile phone when they carry out the kidnapping, but when they usually don't act, where is this mobile phone?"

Han Siyan's eyes lit up, and she glanced at Wu Zhihong, and finally felt that the neuropathy in front of her seemed to have reached a key point.

Kang Tian saw the excited eyes of the people below, and he was even more proud: "If they don't usually act, in order to keep in touch, then this second mobile phone should be carried with them." Seeing that everyone nodded, he raised his eyebrows and said the climax of the topic:

If this assumption is true, then the second phone can be found by comparing whether there is a number that closely coincides with the movement trajectory of the number disclosed by the suspect. Everybody... Do you think so?"

Wu Zhihong smashed a punch in his palm, turned to the other policemen and ordered: "Hurry up and contact mobile, telecommunications, Unicom and other companies to find the same number as the female worker and the two missing security guards." ”

"Oops... Kang Tian stopped a few policemen who were about to call, and said in a drag: "This police comrade, don't be so anxious." This kind of big data mining is a piece of cake for this expert. Sister Siyan, before you came, I had already found these phones. I only played the game for a while to celebrate the victory. ”

Han Siyan smiled helplessly, this thing hadn't forgotten that she was angry and pressed him on the table, but she was really much more pleasing to the eye now when she looked at Kang Tian.

Several phone numbers were displayed on a large screen in front of the conference room, followed by an electronic map of the entire city of Jinbei, and the historical trajectory of each number was marked on the map in a different color. Then Kang Tian marked the mobile phone movements of the female worker and the two missing security guards who had been found before on the map with black lines. Sure enough, the lines coincided in pairs.

"Kang Tian, check the last call and time of the female worker's new mobile phone, as well as Xiao Zhang, immediately contact the technical detective to track down the location of the two new mobile phones of the missing security guard. ”

Bang bang. Kang Tian snapped his fingers a few times and pointed to the screen behind him with his thumb. Han Siyan saw a red number on it, and a small red flag flashing on the electronic map.

"This is the last call the woman makes, and the last position of this phone. Why are you looking for technical detectives, do you want them to have a supper?" Kang Tian had a very powerful expression.

Han Siyan looked at him and shook her head, turned around and gave an order: "Team Wu, you take someone to this location, ask the comrades from the local police station to help, and first conduct a control and investigation of this location." Wait for support. ”

"Yes!"

"Xiao Zhang, you take the metal detector, go to the place where the female worker's mobile phone last disappeared to search, find this mobile phone, and hand it over to the technical investigation department to decipher the code. ”

"Yes!"

"Kang Tian, what is the status of the mobile phones of the two missing security guards?"

"Oh, both phones came to this place after both of them went missing. But Sister Siyan, the bad news is that the two of their mobile phones lost signal on the same day, and I guess they should have abandoned the IC card and changed it to another number. ”

"Well, you have a point. Li Tong, you take a group of people and work with the local police station to find out the last hiding place of these two people, and see if you can find anything. ”

For a while, the building where the task force was located was suddenly full of people, and the police/lights on more than a dozen police cars in the parking lot flashed, whining and running in different directions.

After Feng Zhenyu got Han Siyan's call, he rushed to Jinbei from the capital overnight with several police officers from the Special Affairs Department.

On the way, his phone almost didn't stop, and after talking to Lu Qiang, he called Han Siyan, who was the commander of the scene.

"Team Han, your discovery is very important. From the analysis of the current clues, the last call made by the female worker is likely to be the leader of the gang. Tell the comrades at the scene not to act rashly. Secretly verify the location and status of the target person, and notify reinforcements. I have already contacted the Lu Bureau just now, and he will immediately mobilize the comrades of the city special police detachment to cooperate with you. I have also asked the leaders of the ministry for instructions, and they will coordinate the special forces of the garrison to reinforce you. ”

“。。。 I said that the closure of the office, the arrest of a suspect does not need such a big move, right? Why do you still use troops? ”

"Team Han, don't be careless, if this person is really the leader of this gang, then you are likely to face an extremely vicious and fierce opponent beyond common sense. No matter how careful you are, you should be prepared rather than be caught off guard. ”

"Yes!"

。。。。。

It was already late at night when Moon Shadow arrived in Jinbei, and she asked the driver to park the car in the parking lot of another neighborhood in the distance, and then went to the stronghold of the original sect leader of Jinbei alone.

This is a community with more than 20 high-rise buildings, except for a few residents who came out to walk their dogs, the whole community is silent. Occasionally, one or two night returnees appeared, and they also walked by in a hurry, and only a few rooms on each high-rise were lit up.

The original leader's stronghold was in a unit on the nineteenth floor of Building 2. Moon Shadow flicked a flap on the door, revealing the fingerprint reader inside. She put her thumb on the reader, and after an inaudible tick, the lock clicked open.

Moon Shadow pushed the door in, and the room was quietly immersed in moonlight.

Instead of turning on the light, she walked into the study, which was empty except for a large desk and a large chair. On the wall opposite the desk is a landscape ink painting.

Moon Shadow fumbled underneath the desk for a while, and with a slight click, the landscape painting moved to the side with the sound of a slight mechanism. Revealing a four-inch square screen inside.

Moon Shadow pressed her palm to the screen, and after the screen scanned her five fingerprints, a secret door appeared on the wall behind her desk. The secret door silently slid open to both sides, revealing a one-meter-high, half-meter-wide dark compartment behind it. Inside was a quaint wooden plate with deep runic patterns carved into it.

If Han Siyan saw this wooden plate, she would be surprised to find that the pattern on it was very similar to the vampire wooden plate found in the maintenance shaft. There is also a groove in the middle of the wooden disc with a short sheath stuck in it.

It is said to be a short knife, but judging from the shape of the scabbard, it looks more like an elongated dagger. The scabbard appears to be made of leather, but the lines and uneven surface on it do not match the skin of animals known on Earth.

In the dark space, a ray of light is occasionally seen floating out of the wooden plate, and then attracted by the scabbard, disappearing into the unsightly lines on the surface of the scabbard.

Perhaps sensing Moon Shadow's gaze, the short knife suddenly swooped upward, revealing a dull blade, as if wary of Moon Shadow. For a while, even the moonlight in the study was infected with a layer of murderous atmosphere.

Moon Shadow was taken aback, she didn't expect this legendary ancient treasure to have a spirituality of its own. It's no wonder that the Shining Spirit Knife has always been one of the most famous treasures in the sect.

She quickly moved her lips and recited a large incantation. After a long while, the Shining Knife slowly retreated into its scabbard.

。。。。。

About a kilometer away from the neighborhood where Moon Shadow is located, there is a branch road, and at this time, the police have set up a cordon on both sides of the road.

In the middle of the road, more than a dozen police cars with their lights and lights turned off were parked, and dozens of police officers were scattered around. Some of them wore police uniforms on duty, some wore black SWAT uniforms, and more than a dozen wore civilian clothes.

But no matter what they were wearing, everyone at the scene was armed with guns and ammunition. Especially the dozen or so special police officers are armed to the teeth. Steel helmets, shields, assault rifles, and body armor were all missing, and they were standing in two rows listening to the police officers who led the team as they mobilized before the battle.

Among the police cars was a huge command van parked with bright lights and several operators busy in front of the screen. There were also Zhao Quanyong, Han Siyan and Lu Qiang who had just arrived from home standing behind.

Where there is Han Siyan, there is a high probability that Kang Tian exists. As a "professional who provided important clues", he was triumphantly sitting in front of the largest screen, instructing the other operatives to work.

"It was reported that two drones equipped with infrared sensing cameras had entered the sky over the community and were waiting for instructions. A drone operator reported.

"Good. According to the previous mobile signal positioning, the last position of this phone should be here. Before several high-ranking police officers at the scene could speak, Kang Tian had already begun to arrange unceremoniously.

He pointed to the electronic map of the community on the screen and said: "The buildings in this community are two buildings side by side, and the mobile signal positioning is the conjoined building of Building 1 and Building 2. Two drones, one scanning from east to north and the other from west to south, in order from bottom to top, let's do it. ”

The two police officers who were in charge of controlling the drone ignored him, looked back at Lu Qiang and a few others behind him, and said in his heart: Where did you come from?

Lu Qiang's face was expressionless, as a leader who has led the criminal investigation work for a long time, he has his own official authority. It's just that today I ran into this stunned young man from the ministry. The previous experience of solving the case made him have no plan for Kang Tian, and he was quite disgusted when he thought of the behavior of one play.

But he also knew that this case was different from the criminal cases he had been exposed to before. And now that advanced reconnaissance methods are emerging in an endless stream, he has not been on the front line for a while, and he can't find anything wrong with Kang Tian's fingers for a while.

An official has a skill, and he will not express his opinion casually when he encounters something that he is not sure about. Generally, I will find someone I can trust to deal with it first, no matter whether the result is good or bad, I can take care of it later.

He looked sideways at Han Siyan, Han Siyan understood what Lu Qiang meant, and said:

"Wait a minute, we have to determine what exactly we want to scan?" Although Han Siyan also had a headache about Kang Tian's self-talking, after a period of contact, she was more assured of Kang Tian's professional level. And she originally planned to let the drone do the first round of reconnaissance first, but Kang Tian said it first.

In any case, first let this emotional intelligence idiot hit the wall, and the on-site command must always be clear.

"Of course, it's to scan which room has someone first, why don't you start yet?" Kang Tian didn't realize.

"What does it mean if there are people in the room scanned? This community is a mature community, and it's normal for people to have people in the room. ”

"That... Then how do you find it?" When it comes to hacking technology, Kang Tian is not convinced, but when it comes to the elements of reconnaissance, he is blind.

"We are in a situation where we don't know if the target is in the neighborhood or where the other party is exactly. So let's do the first round of scanning, do a elimination method, exclude the unoccupied room, and see if there are any suspicious people. Xiao Duan, Xiao Wu, each of you scanned each of the residents on the floor in order from top to bottom. ”

Seeing that Kang Tian was looking at herself a little pitifully, her heart softened: "Kang Tian, please build a three-dimensional model of Building 1 and Building 2, and mark the excluded rooms and suspicious rooms later." ”

"Well, look at me. As long as it is the work given by Han Siyan, Kang Tian has always been a fart: "This real estate was built by the Third Urban Construction Bureau, and their server has all the models of the community, including the drawings of the sewers. I'll find it out for you in five minutes. ”

"Oh, you're pretty good... I need to know the owners of these houses. ”

"It's simple, I'll go into the server of the housing authority to see, and find out all the registered homeowner information... It's also five minutes. ”

"Can you get this too?" Kang Tian, it seems that I really can't underestimate you. "Han Siyan finally found the joy of working with Kangtian, and these materials used to go through many procedures to get them. Where it is like now, it's like storing it on your own hard drive.

"Cut, you don't look at who I am, I don't believe you will ask him the next time you see the head of the head, how did he beg me to enter the public security BU at that time. ”

Lu Qiang and Zhao Quanyong's faces were a little dark, when the two of them didn't exist, they discussed the issue of illegal evidence collection so blatantly.

Zhao Quanyong coughed twice, but unfortunately Han Siyan and Kang Tianzheng had a heated discussion, and both of them filtered his cough as white noise.

“。。。。 I said Kang Tian, can you find out the mobile phone number that has been active in these two buildings for a long time? ”

"It's not a big problem, but it takes a long time to get data from the three major operators, and the algorithm analysis will take a long time... In this way, Jinbei University has a high-performance cluster, I will adjust it. ”

Lu Qiang couldn't stand it anymore, and said: "Xiao Han, I'll go out to smoke a cigarette, and I'll be called for something." ”

"Hey, Lu Bureau, go get busy... ”

Zhao Quanyong and Lu Qiang shook their heads together, and got out of the command car with a wry smile.

Soon, two drones were already flying over buildings 1 and 2. The drone with its silent design flies slowly according to the operator's path, and the infrared detector loaded under the fuselage is working in a flash.

"Marking the room where there are people, and then marking the people who are still in the room, this point needs to be focused on if you are not sleeping. Han Siyan gave the operator an order.

Infrared penetrational detection technology is currently only mastered by the military, and the infrared detection used by the police can only penetrate glass windows. In addition, it takes time to imaging, so the speed of drone scanning cannot be faster.

Fortunately, Han Siyan is not too anxious, after all, this is the last place where the target appeared a few days ago, and it is difficult to say whether it is still there. Even if he were, the target would not have guessed that the police had already discovered his location at this time. There should be enough time for the drone to search slowly.

Red human bodies gradually appeared on the screen, most of them lying flat, and it seemed that they had fallen asleep. It was quiet in the command car, and everyone patiently watched the images scanned on the screen one by one.

"Sister Siyan, I have a big discovery here... Kang Tian broke the silence and beckoned to Han Siyan.

Han Siyan was annoyed by Kang Tian's name for her sister to come and go, but now was not the time to have a seizure, she walked behind Kang Tian and asked angrily, "What did you find?"

"Hehe, don't worry, sister. I looked up the last few calls from this number while I waited for the number to match, and then focused on tracking a few first. You see, this is the phone number where the target number last called, do you know when the target made this call and where it was made?"

"Getting to the point. ”

"Here's the point, the target's last call was late at night before you discovered the secret of the repair shaft, at the back of the Kate Building. ”

"Shhh And who did he call to?"

"He just called this number, a mobile phone number. Kang Tian identified a string of phone numbers: "What's more interesting is that do you know where this phone is now?"

The light in Han Siyan's eyes froze: "Could it be that this mobile phone is in the community now?!"

"You're so smart! This phone entered the neighborhood twenty minutes ago, and is now located in the area of Buildings 1 and 2. ”

Han Siyan quickly jumped out of the command car and walked in front of Lu Qiang and Zhao Quanyong, who were smoking outside the car: "Report to Lu Ju and Zhao Team, and find that the suspicious target is in the community at this time." ”

She briefly reported what Kang Tian said to Lu Qiang and Zhao Quanyong, and the faces of the two became serious.

Lu Qiang first said: "Immediately block the entrances and exits of Building 1 and Building 2, and only allow entry and exit." ”

"Lu Ju is right, you can't let the target person escape. In order not to startle the snake, it is recommended that the SWAT secretly infiltrate the community now and occupy the tactical points around Buildings 1 and 2. Zhao Quanyong added.

"Okay, Jeon Yong, you and Xiao Han will lead the team over now, and I'll coordinate with other police departments in the command vehicle. Let's go!"

"Yes!"

As the muffled command continued to sound, the special police and the criminal police got into their respective cars, and more than a dozen cars turned off their lights and galloped towards the community.

After a while, the entrances and exits of the community have been blocked by police cars, and the sentry box is also controlled by the police.

Under the astonished eyes of the community security guards, a team of SWAT officers in black SWAT uniforms armed with assault rifles silently surrounded the direction of Building 1 like flowing water.
