Guo Zhan and Tian Feilong also looked at the cafeteria with a thoughtful look, and after listening to Xia Ruofei's words, Guo Zhan also had a flash of inspiration and shouted, "There is a clue!"

Only Tian Feilong was still frowning slightly, obviously still having no clue. Pen % fun % Pavilion www.biquge.info

He couldn't help but ask, "Captain, squad leader Xia, what is the clue?"

Guo Zhan looked at Xia Ruofei with a smile and said, "Blood wolf, come on!"

Xia Ruofei gently stroked Xiao Hei's smooth fur, and asked with a smile: "Feilong, think about it, that group of people is not a small target, and when they left, they also took Professor Liang with them, and there may be other experimenters, how did they avoid surveillance?"

Tian Feilong looked at the cafeteria next to him, and analyzed: "These people don't know how to stealth, and they rule out the possibility of escaping the campus directly through the sewers, that is, they have prepared transportation in advance, right? And it is likely to be that kind of airtight van ......"

Xia Ruofei snapped his fingers and said, "That's right! This is the school cafeteria, and there must be a lot of ingredients consumed every day, so ......"

"The truck transporting the ingredients!" Tian Feilong immediately said loudly with the same eyes as he was.

Xia Ruofei smiled and nodded.

At this time, Guo Zhan's confidential mobile phone vibrate, he picked it up and said a few words, and after hanging up the phone, he said with a smile: "Those little rabbit cubs have arrived, let's go over to meet first, and then go to the school security office to check the monitoring!"

They had been drilling in the sewer for so long just now, but in fact, it was not very far to return to the laboratory building from the ground, a distance of four or five hundred meters, so soon the three of them returned to Professor Liang Qiming's exclusive laboratory building.

The personnel of the two teams have arrived, in addition to the old Luo squad leader who has died, Jin Gang, who was seriously injured and hospitalized, and a team member who stayed in the general hospital to take care, there are also 9 team members.

The people who could be brought out by Guo Zhan to perform such an important task were all experienced veterans, and naturally they were also very familiar with Xia Ruofei.

Everyone met again with an excited hug and greeting.

However, Xia Ruofei and Guo Zhan were in a hurry to check the surveillance video, so everyone didn't waste too much time, they didn't even have time to wash off the stains on their bodies, so with a trace of unpleasant smell, they came to the school security office under the leadership of a police officer.

This police officer Li explained the situation to the security chief, and the director naturally cooperated unconditionally, personally took everyone to the monitoring room, and instructed the staff to call up the monitoring records according to Guo Zhan's requirements.

Yesterday's encounter took place at about five o'clock in the afternoon, and Guo Zhan directly asked to see the surveillance footage of the second canteen at that time.

As Xia Ruofei expected, the location where they tracked the smell disappeared just now was the monitoring blind spot of the second canteen, and none of the probes photographed that location.

But after a while, a white van appeared in the probe - this car was driving out of the open space on the side, and it was impossible to avoid all the surveillance probes as it was about to leave the cafeteria and drive out of the campus.

"Stop!" Xia Ruofei shouted.

The staff immediately pressed the button, and the picture froze.

Xia Ruofei pointed to the van on the surveillance screen and asked, "Director Luo, do you know this car?"

Director Luo of the University Security Office said with a wry smile: "There are so many cars entering and leaving the campus every day, and we can't know every single one, but those who can enter the campus must be vehicles with access cards, and most of this car is for the canteen to deliver food, or I will call the logistics Lao Xu over to identify it?"

"Then I'll trouble you!" Xia Ruofei said politely.

Soon, Director Xu of the Logistics Department, who was also working in the same building, also came to the monitoring room, and he glanced at the LOGO on the truck and immediately said: "This is the delivery vehicle of the Oasis Agricultural and Sideline Products Company! The ingredients for the five canteens of our school are all outsourced to the Oasis Company, and they will run several times a day to deliver food!"

Xia Ruofei and Guo Zhan glanced at each other, and then Xia Ruofei said, "Can the picture be enlarged a bit?

We have a couple of HD cameras on the main road of the school. "If the car is leaving the campus, it must be going through the main road." ”

After speaking, he skillfully operated on the computer and called up the historical record screen of another monitoring probe.

Sure enough, after a while, the van appeared in the picture, not only the license plate number was clearly visible, but even the occupants in the car could be seen clearly.

Xia Ruofei quickly wrote down the license plate number, asked Officer Li to coordinate the police to go to the Oasis Company to investigate the situation of the car, and then said to the staff: "Please take a few pictures of the picture that can clearly see the people in the car just now, thank you!"

After the staff took a screenshot, everyone looked at the surveillance for a while, and the van was started about 20 minutes after the shootout, and then drove directly out of the campus.

Then Xia Ruofei asked the staff to look back for the monitoring at the door of the canteen, and found that the car came to the second canteen at a little more than four o'clock, and then parked directly in the open space on the side, until it left at more than five o'clock.

The timing coincided!

After watching the surveillance, Director Luo of the Security Department took Xia Ruofei and others to the reception room next door, sat and drank tea and chatted together, waiting for the results of the police investigation.

About 20 minutes later, Officer Li also came to the reception room, and as soon as he entered the door, he said: "I have found out clearly, the truck with the license plate number just now happened to be sent for repair yesterday, and it did not come out at all! Moreover, every car in their company is equipped with GPS, and we checked the trajectory of the car yesterday, and it is true that it went from the company to the repair shop, and did not come to Sanshan University at all." ”

"Deck!" Xia Ruofei and Guo Zhan said in unison.

At this time, Director Xu of the Logistics Department also walked into the reception room and said: "Officer Li, I just went to check the records of the second canteen, there were no ingredients in the warehouse yesterday afternoon, and the car was only parked on the side of the second canteen yesterday, not to deliver food!"

In this way, the car that appeared in the surveillance is very suspicious, and it can basically be confirmed that the gang used this fake truck to kidnap Professor Liang out of the campus without knowing it.

Guo Zhan stood up, shook hands with Director Luo and Director Xu, and said, "Thank you very much for your support!"

The two directors also knew that the person in front of them was not small, so they hurriedly said a few polite words.

Guo Zhan turned to Officer Li again and said, "Officer Li, please coordinate with your superiors, we need to go to the command center of the Municipal Public Security Bureau immediately and use the Skynet system to find the trajectory of this van!"

Officer Li was assigned to the scene of the shootout to take charge of the situation temporarily, and naturally he was very aware of the seriousness of yesterday's incident, and it is no exaggeration to say that it has risen to the level of national security.

So when he heard this, he said without hesitation: "No problem! Let's go over now, I'll ask the leader on the way!"

......

Half an hour later, the group came to the command center of the Municipal Public Security Bureau.

Guo Zhan only brought Xia Ruofei and Tian Feilong in, and the other team members were all on standby in the car.

The command center of the Municipal Public Security Bureau is a hall of thousands of square meters, and there is a huge LCD screen on the front wall, which displays the monitoring images of various hot spots in the city in real time.

Officer Li had already reported the situation on the way, so when Xia Ruofei and his party came to the command center, Deputy Director Lu of the Public Security Bureau in charge of criminal investigation personally received them.

This is also because Director Chen Bo didn't know that there was Xia Ruofei among the military people this time, otherwise he would definitely come forward to receive him in person.

Deputy Director Lu shook hands with Guo Zhan and said, "Colonel Guo, we have checked the surveillance footage near the north gate of Sanshan University at five o'clock yesterday, and we have also found the van. ”

The number of the lone wolf commando is top secret, so the military did not inform Guo Zhan of his position, but only his military rank is colonel.

Guo Zhan immediately said: "Director Lu, can you analyze the trajectory of this car?"

"Our technicians are doing the analysis and it shouldn't be a big problem. Deputy Director Lu said, "A few people here, please!"

As the capital city of the developed provinces in eastern China, Sanshan is also in the forefront of the country in infrastructure construction, and the construction of the Skynet project in Sanshan City started relatively early, and the software and hardware facilities are significantly ahead of the cities in some underdeveloped provinces.

At present, the Skynet system of the Sanshan Public Security Bureau can use the license plate number recognition function to add time and other algorithms to the images transmitted by a large number of cameras in the city to automatically calculate the approximate driving trajectory of a certain car.

In addition, due to the increasing number of high-definition cameras, the facial recognition function is also improving.

The Skynet system is also playing an increasingly important role in solving cases by public security organs.

Everyone came to the big screen, and Deputy Director Lu gestured to the technician who was operating the computer.

A surveillance screen immediately appeared in a large area in the center of the big screen, which was captured by a security probe at the north gate of Sanshan University.

I saw that the white van was slowly driving out of the north gate, and after going out, it turned right onto Yangfan Road.

It wasn't until the car disappeared from the surveillance range that the scene immediately shifted to the range of another probe, and the van soon reappeared in the range of this probe.

On the right side of the big screen is a map, on which a red line starts from the north gate of Sanshan University - this is the trajectory of the white van.

Of course, this is only the most likely trajectory analyzed by the Skynet system, after all, the monitoring probe can not achieve full coverage, the car will always drive into the monitoring blind spot, and then it may take a while to appear in another monitoring range, in the blind spot during this period of the car's driving trajectory, it can only be comprehensively analyzed and simulated through factors such as time difference, vehicle speed and the next location.

This red line, which represents the trajectory of the van, leads all the way north.

Tian Feilong frowned slightly and said, "Could it be that they really hid in the mountains?"

Xia Ruofei said calmly: "It's unlikely, our reaction after the incident was still very fast, plus there was a lot of traffic in the urban area at that time, and the direction out of the city should have been controlled at this time, and the possibility of them taking Professor Liang to break through successfully is very small." ”

Guo Zhan also nodded and said, "I agree with Ruofei's opinion. ”

Sure enough, after a while, the red line stopped when it reached the vicinity of Xinyuan Road in the northern part of Sanshan City.

"The target disappeared here and was never seen again within range of any of the city's surveillance probes," said the police officer in charge of the technology. ”

Deputy Director Lu immediately said: "Demarcate the area immediately and send someone over to investigate!"

"Yes!" said the police officer in charge of technology.

The distribution of monitoring probes at the junction of urban and rural areas is not as dense as that in urban areas, and there are some monitoring blind spots.

The truck could only be parked in those areas, otherwise it would have been photographed by other probes.

A large number of police forces were quickly dispatched.

Tian Feilong asked, "Squad Leader Xia, do you want to take Xiao Hei with the police?"

Xia Ruofei said: "I feel that even if I find the truck, it is unlikely that I will get further clues, but I still have to go there." ”

After speaking, Xia Ruofei set his eyes on Guo Zhan.

Guo Shishi nodded slightly as soon as he groaned.

Soon, Xia Ruofei and Tian Feilong boarded a police car with Xiao Hei and went to the areas just demarcated to investigate.

And Guo Zhan is in the command center of the Public Security Bureau.

With the auxiliary analysis of the Skynet system, in fact, the scope of investigation is not large, and there is no suspense in finding the car.

Sure enough, before Xia Ruofei and their car arrived at their destination, news came from another team on the intercom - they had found the van.

So Xia Ruofei and his team immediately changed their route and drove directly to the location of the van.

This is an abandoned machine shop on the northern outskirts of the city, and the white van is parked in the factory's overgrown yard.

This area is a blind spot for surveillance.

Xia Ruofei got out of the car and immediately ran to the van with Xiao Hei, the police had already been ordered to cooperate fully, so they did not stop Xia Ruofei and Xiao Hei.

Opening the back compartment, Xia Ruofei patted Xiao Hei's head, and Xiao Hei jumped up like lightning.

It sniffed around inside the carriage, and Xia Ruofei asked, "Xiao Hei, is there the smell you smelled just now in the car?"

Xiao Hei immediately snorted twice, and then nodded very humanely.

Although the fact that the gang used this car to sneak into the campus and then kidnapped Professor Liang out has been basically determined, after getting a positive answer from Xiao Hei, Xia Ruofei is still a little excited.

Now it's 100% certain!

Xia Ruofei hurriedly beckoned to Xiao Hei and asked him to get out of the car.

"Xiao Hei, can you sniff around here and see if you can find the smell just now?" Xia Ruofei said.

Xiao Hei immediately sniffed around the van, and after a while, it shook its head at Xia Ruofei in frustration.

The police also felt very new to Xiao Hei's humanity, but their attention was more focused on finding clues.

Seeing that Xiao Hei didn't find any clues, Officer Wang, who led the team, couldn't help but ask, "Do you need our police dogs to come over?"

Tian Feilong said with a smile: "Xiao Hei is much more powerful than a police dog. Yesterday, the police dogs of the SWAT team did not find any clues, but today Xiao Hei went out and dug up this clue by force! So it is useless for you to send police dogs here. ”

"Then how can there be no smell left?" Officer Wang said puzzled, "There is still a residual smell in the car!"

Xia Ruofei and Tian Feilong glanced at each other, and said in unison: "They changed cars!"

Xia Ruofei opened his mouth and said, "Let's go!"

Xia Ruofei thought for a while and then said: "Officer Wang, please leave a few comrades to check this car and see if there are any clues left!" Feilong, immediately use a confidential mobile phone to contact the wolf king, and let the comrades in the command center use the Skynet system to conduct in-depth analysis, and divide the blind spots along the way in chronological order, and see which blind spots can allow them to change cars calmly!"

"Understood!" Officer Wang and Tian Feilong said at the same time.

Xia Ruofei took a deep look at the van and said, "Let's go! Since we have caught this clue, they will definitely not be able to escape!"
