……………………

At 8:46, Han Bo, Zhu Qianli, head of the criminal police detachment of the Dongping City Public Security Bureau, and Feng Chaoyang, an investigator of the Dongping City Justice Bureau, rushed to Tenglong Industrial Zone.

The special police, armed police and Longhua branch police who participated in the operation have been withdrawn, and there are only a few police officers from the police station who maintain order at the gate of the factory and inside, and they walked into the workshop, only to see that Qian Dahai, deputy director of the Criminal Investigation Bureau, was organizing the personnel of the special case team to investigate the scene, and the police dog teaching brigade also had people and dogs coming, and three policemen with dogs were leading the police dogs to sniff everywhere in the workshop.

"Han Bureau, look at this. ”

Never so passive, Qian Dahai was unprecedentedly angry, pointing to a pile of large and small evidence bags on the rusty operating table, gritting his teeth and saying: "A total of 8 pinhole cameras, installed on the iron door, under the eaves of the outer wall and several windows, connected to the monitoring host, the host is connected to the computer, the computer is open 24 hours a day, 24 hours connected to the Internet, remote monitoring, 360 ° no dead ends, Xiao Zhao said that this system and the software he uses also have the function of reverse dialing to the receiver when the alarm is triggered." ”

There is no doubt that Gu Sicheng not only knew about the action in the early morning, but also saw it clearly!

In turn, it is the first time that such a thing has been encountered by the public security organs.

Acting so cautiously, modus operandi so sophisticated, and even using high technology, he went to work in the mining area before graduating from junior high school, did not receive higher education, and there was no evidence that he was wary of computer network technology, Han Bo even doubted that the opponent was the Gu Sicheng he knew before.

"Can you go in the direction to recover the stolen goods?" asked Han Bo looking back.

"Xiao Zhao, you are engaged in computers, you report to the Korean Bureau. ”

"Yes!" A policeman wearing gloves to sort out the signal cable that had just been removed hurriedly put down his work and ran over, standing up and saluting: "Report to the Korean Bureau, we came in and found that there was monitoring, immediately check the computer, confirm that the system and software used have the functions of remote monitoring and reverse dialing alarm, and immediately report to the detachment to use technical means for reverse tracking." ”

"Talk about the point!" Qian Dahai was on the fire, and suddenly snorted coldly.

Xiao Zhao was startled and hurriedly said: "We have to figure out this software first, figure out how to dial the number, in order to lock its IP address, and then lock its real address according to the IP address." Theoretically and technically there are no problems, but in time ...... It could take seven or eight hours at the earliest, after all, we had to crack the software first, and we needed the help of the telecommunications department. ”

"Then hurry up. ”

"Yes!"

Seven or eight hours, what's the joke?

If nothing else, Gu Sicheng ran away as early as when he found out that the workshop was surrounded by the public security police regiment, so he wouldn't sit there stupidly and wait for you to track it in reverse, and wait for you to take a large team of people over to arrest him.

The reason why the technical detective continued to track in reverse was that "a dead horse should be a live horse doctor", and second, he could find out where he was three hours ago, so as to figure out his activity trajectory and see if he could summarize the law of his activity. More importantly, it can find out what identity he appeared in that position a few hours ago, or whether he has impersonated someone else's identity.

Of course, even if he can figure it out, even if he does impersonate someone else's identity, with his cautious character, it is entirely possible to change his identity again.

Han Bo took a deep breath, accompanied by Qian Dahai, walked around the workshop, looked at the wire bed where Gu Sicheng and the three of them had slept on, turned on the old color TV they had seen, and stood behind Xiao Zhao to look at the desktop computer they had used.

"Report to the Korean Bureau, there is nothing in the computer. ”

"Deleted?

"No, this computer only has monitoring software, which seems to be specially used to monitor the situation in the factory. ”

As soon as Xiao Zhao's words fell, Qian Dahai added with a gloomy face: "Other places have been cleaned up, the sheets and bedding have been cleaned neatly, cleaned inside and out, and even the trash cans have been emptied, but he has not deliberately cleaned up the fingerprints and footprints, presumably he knows that we have these and doesn't care about being extracted by us." ”

This bastard didn't just come prepared, but he was well-planned and prepared a lot in advance.

I don't know what Gu Sicheng will do next, the more Feng Chaoyang thinks about it, the more nervous he becomes, and he frowns and says, "Han Ju, do you say he has any other accomplices?"

"It's unlikely, first, the more people there are, the easier it is to be exposed, and second, he won't trust others easily. ”

Han Bo looked around the workshop again, and said expressionlessly: "He must have run away, not only did he run away, but it is estimated that Qian Xiaowu and Zong Hao also ran away." We lost this round, and we lost in solving the case. If you are not in such a hurry to act, first try to ask the Thai police to control Qian Xiaowu and Zong Hao, and the result is likely to be completely different. ”

When handling cases, the public security organs pay attention to "quick investigation and quick cracking" and are accustomed to "quick battles and quick resolutions", not to mention that Gu Sicheng is not an ordinary fugitive, he has explosives in his hands!

No matter who else is in command, everyone will take action immediately.

The more Qian Dahai thought about it, the more depressed he became, and he slapped his thigh with a snap: "Who would have thought that he would be so cunning, who would have thought that he would spy on us in turn?"

"Yes, you didn't expect it, I didn't expect it either, to sum up the lesson, you must not make the same mistake again. ”

Han Bo didn't dare to have even a little contempt, and while walking outside the workshop, he admonished: "Old Qian, Zhu Zhi, after the investigation here, you go back and continue to study the case, and after the direction of the technical investigation has the results, immediately organize the police to go to the foothold where he stayed to investigate and collect evidence, find out what he has done these days, who he has seen, and see if he has left anything in the place where he has stayed." ”

"Han Ju, what about you?"

"I'm going to Hong Kong, I'm going to leave now, and I'm going to get back before dark. ”

"To Hong Kong?"

"It turns out that our basic work is not solid enough, what we know about Gu Sicheng is still Gu Sicheng six years ago, our experience six years ago is clear, and there are detailed materials on his performance during his sentence in the No. 3 Prison in your province, but we don't know anything about the situation during his sentence in Stanley Prison in Hong Kong, I don't know who he met in prison, I don't know what he learned in prison, in short, knowing oneself and knowing the other can be invincible, and the situation during his sentence in Stanley Prison must be clarified. ”

Gu Sicheng used to know how to use a computer, maybe he could type, chat, send and receive emails, but he definitely wouldn't assume this remote monitoring system.

What does this mean, it shows that he has studied carefully.

If he has not only learned computer network technology, but also electronic and even radio technology, it means that he has the ability to make remote-controlled-explosive-bombs, can monitor remotely, and can also remotely detonate, thinking of this, Qian Dahai couldn't help but gasp!

……

As Han Bo expected, Gu Sicheng had checked out and left the Longjiang Hotel three hours earlier.

When waiting for the room attendant to make rounds at the front desk on the first floor, he stared at the surveillance in the lobby for several minutes, and even smiled playfully.

He really wanted to find a hotel nearby to open a room, install a remote monitoring system, want to confirm whether the Public Security Bureau would find the Longjiang Hotel, want to know whether the Public Security Bureau has the technology to reverse track through the Internet, and want to see how Han Bo will swoop down again.

Unfortunately, due to previous negligence, it was difficult to achieve this wish.

First, there is no pinhole camera on hand, no monitoring host, no signal line, and no extra computer;

Second, in order to ensure that nothing goes wrong, the name "Lu Zhiwei" can no longer be used, and there is only one ID card on the body "Lu Zhiwei", how to open a house without an ID card, the top priority is to find a safe place to contact a few more ID card dealers, buy more ID cards, pick a few of them even if they are only six or seven points similar, and prepare a few more identities in case of emergency.

Where do I go next?

"Smiling Tiger" knows that the first foothold is in Longhua District, and it is likely to take advantage of Yu Lin's post to see the opportunity of the labor and management to go to the McDonald's in Futian District by locking the IP address, and now it is possible to trace it back to the Luohu District through network technology, and there are only a few districts in Shenzheng, will he think that the labor and management will go to Anbao District or other districts that he has not been to before.

The most dangerous place is probably the safest place!

Thinking of this, Gu Sicheng couldn't help laughing, tightened the backpack on his shoulder, reached out to stop a taxi, pulled the car door and said with a smile: "Master, go to Guangming Road, Longhua District." ”

"Boss, Guangming Road is long, do you want to go to Guangming East Road, Guangming Middle Road or Guangming West Road?"

Why did you go to Tomita Ward to eat McDonald's the other day?

When it comes to surfing the Internet, there are many places with wireless networks.

On foreign fast food, KFC, McDonald's, and Pizza Hut can be found everywhere.

The reason why I ran so far to eat McDonald's is actually to get familiar with this amazingly changed city, the terrain is not familiar, and I can't figure it out from the east, west, north and south, how to deal with the "smiling tiger"?

While strolling around, Gu Sicheng kept thinking about whether it was safe here and whether it could be used as a foothold.

The hesitation just now is not that there is nowhere to go, but that there are too many places to choose, and I didn't make up my mind for a while, but now I have made up my mind, so I am not so entangled, I put down my backpack and said: "Master, go to the modern rehabilitation hospital, I know the approximate location, and I know that on Guangming Road, it is really not clear whether it is the East Road or the Middle Road." ”

"Modern hospital, I know, is on Guangming Middle Road, next to which is a military guest house, which I don't go to much now, but I used to go there often. ”

"That's for you. ”

"You're welcome. ”

This boss is a good person, and he also scattered a soft China.

The driver looked up through the rearview mirror, picked up the lighter and lit it, rolled down the window through a gap, and continued to drive while quietly asking, "Boss, do you go to the modern hospital to see a doctor or a patient?"

"Visiting a relative. Gu Sicheng pretended to be worried and sighed lightly.

Good people should be rewarded.

The driver hesitated for a moment, but still reminded kindly: "Boss, you know that you are not a local by listening to the accent, there are many scammers now, and it is not a trivial matter for your relatives to see a doctor, so you can't be deceived." ”

"Master, I don't understand, are you saying that modern hospitals are not good?"

"Let me tell you clearly, that is a liar hospital, privately opened, the advertising is overwhelming, I used to raise a group of nurseries to go to regular big hospitals to pull people, and also gave us these business cards for rental, saying how much money was paid to pull a patient, and it was later exposed by the TV station, no one from the local people went, who dared to go!"

Gu Sicheng did go to the Modern Rehabilitation Hospital, but there were no relatives who were hospitalized there, and he did not go to see a doctor himself, but used the Modern Rehabilitation Hospital as a hotel as a foothold for the next few days.

Liar hospital, who doesn't know?

As long as you are hospitalized, as long as you can spend money with them, they will not care if they have an ID card or not, and more importantly, the public security is unlikely to go there to make rounds.

In any case, people are also kind.

Gu Sicheng pretended to be surprised, and frowned slightly: "It turned out to be a liar hospital, oops, I want to persuade my cousin." In fact, you can only go to a big hospital to see a doctor, which is more expensive, and the main thing is to be down-to-earth. ”

"Well, I never go to small hospitals, let alone private hospitals. ”

……

Gu Sicheng chatted with the taxi driver without a word, but he was very busy, and at the same time contacted several ID card dealers in QQ Riga to discuss the purchase of ID cards.

Before I knew it, the modern rehabilitation hospital that looked very grand and formal from the outside arrived.

After paying the money and getting out of the car, seeing the driver away, Gu Sicheng quickly looked around, and finally his eyes finally stopped on an office building on the corner diagonally opposite.

It is important to buy an ID card, and I will see it later.

He ran to the sidewalk with his bag on his back, crossed the road, walked for seven or eight minutes, walked into the building, walked around the lobby, and found that the express mail sent by several express companies was all piled up in the corner of the lobby.
