Chapter 513: Nothing

Guo Zhan and Tian Feilong also looked at the canteen with a thoughtful look. After listening to Xia Ruofei’s words, Guo Zhan also flashed a glimmer of light and shouted:
There are clues!

Only Tian Feilong still frowned slightly, apparently still has no clue.
He couldn't help but ask: "What is the clue of the captain and the summer squad leader?"
Guo Zhan smiled and looked at Xia Ruofei and said: "Blood wolf, let's talk about it!"
Xia Ruofei gently touched the black and smooth fur, and smiled and asked: "Flying dragon, you think about it, the group's goal is not small, when you go, you will also have Professor Liang, there may be other laboratory workers, how are they? Avoiding monitoring?"
Tian Feilong looked at the canteen next to him and analyzed: "These people will not stealth, and exclude the possibility of escaping directly from the campus through the sewer. Is that the transportation is prepared in advance? And it is probably the kind of closed compartment." truck……"
Xia Ruofei made a snap and said: "Right! Here is the school cafeteria. There are definitely a lot of ingredients consumed every day, then..."
"The truck that transports the ingredients!" Tian Feilong said loudly as soon as the eyes.
Xia Ruofei smiled and nodded.
At this time, Guo Zhan’s secret mobile phone vibrated. He picked up and said a few words. After hanging up the phone, he smiled and said:
The little rabbits have arrived. Let’s go to the confluence and then go to the school to check the surveillance!

They just drilled in the sewers for a long time. In fact, it was not very far from the ground to return to the experimental building. The distance of four or five hundred meters was enough, so the three soon returned to the experimental building of Professor Liang Qiming.
The staff of the two squads have arrived. In addition to the old squad leader who has been sacrificed, the seriously injured hospital, and a member who stayed in the General Hospital, there are nine players.
The experienced veterans who can be brought out by Guo Zhan to perform such important tasks are naturally familiar with Xia Ruofei.
Everyone met and was excited and hugged.
However, Xia Ruofei and Guo Zhan are eager to watch the surveillance video, so everyone did not delay too much time, they even had time to wash off the stains on their bodies, so with a trace of unpleasant smell, led by a police officer Go down to the school security office.
The police officer Li and the director of the security explained the situation. The director naturally unconditionally cooperated and personally took everyone to the monitoring room and told the staff to transfer the monitoring records according to Guo’s request.
Yesterday's encounter occurred at more than five o'clock in the afternoon, Guo Zhan directly asked to see the monitoring screen of the second canteen during that time.
Not as far as Xia Ruofei expected, they just tracked the position where the smell disappeared. It was the monitoring corner of the second canteen. No probe took the position.
However, after a while, a white van was appeared in the probe. The car was just opened from the side of the open space. It was impossible to avoid all the monitoring probes when the car left the canteen to leave the campus. of.
"Stop!" Xia Ruofei called.
The staff immediately pressed the button and the picture was frozen.
Xia Ruofei pointed to the van on the surveillance screen and asked: "Luo Changchang, do you know this car?"
Luo, the head of the University Security Office, said with a smile: "There are so many cars entering and leaving the campus every day. We don't know every one of them. But those who can enter the campus are definitely vehicles with a pass. Most of the cars are for the canteen, but would I call the old Xu of the logistics to identify it?"
"That will trouble you!" Xia Ruofei said politely.
Soon, Xu, the head of the office in the same building, came to the monitoring room. He looked at the logo on the truck and immediately said: "This is the delivery car of Oasis Agricultural Products Co., Ltd.! Five dining halls in our school. The ingredients are outsourced to Oasis for purchase, and they run several times a day to deliver food!"
Xia Ruofei and Guo Zhan looked at each other and then Xia Ruofei said: "Can the picture be enlarged? Can the license plate number be identified?"
"No problem! We have several high-definition cameras on the main road of the school." The staff said, "This car must leave the campus and must pass the main road."
After that, he skillfully operated on the computer and brought up another history of the monitoring probe.
Sure enough, after a while, the van appeared in the picture, not only the license plate number was clearly visible, but also the occupants in the car were clearly seen.
Xia Ruofei quickly recorded the license plate number, and asked police officer Li to coordinate the police force to go to Oasis to investigate the situation of the car. Then he said to the staff: "Trouble to show us a few pictures of the person who can see the inside of the car. Thank you!"
After the staff cut the map, everyone watched it for a while. The van was started about 20 minutes after the gun battle and then directly opened the campus.
Then Xia Ruofei asked the staff to look back at the door of the canteen and found that the car came to the second canteen at four o'clock, and then stopped directly on the side of the open space until more than five o'clock.
Time just fits!
After watching the monitoring, Luo Zhichang of the Security Office came to the reception room next door with Xia Rufei and others, sat down with tea and chatted, waiting for the investigation results from the police.
After almost twenty minutes, Li police officer also came to the reception room. When he entered the door, he said: "I have checked, the truck with the license plate number just sent it for repair yesterday, and there is no car at all! And every company in their company. All of them installed gps. We checked the trajectory of the car yesterday. It was indeed from the company to the repair shop. It did not come to Sanshan University."
"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: "Police officer, I just checked the record of the second canteen. There was no food in the afternoon yesterday. The car was stopped at yesterday. The side of the cafeteria is not a dish!"
As a result, the suspect in the surveillance vehicle is already very large. It is basically confirmed that the group of people used this deck truck to unwittingly hijack Professor Liang from the campus.
Guo Zhan stood up and shook hands with Director Luo and Director Xu and said, "Thank you very much for your support!"
The two directors also knew that this one was not too small, and he was very polite.
Guo Zhan turned and said to Li police officer: "Police officer, trouble you to coordinate the superiors, we need to go to the city public security bureau command center immediately, use the Skynet system to find the trajectory of this van!"
Li police officer was arranged to take temporary responsibility at the scene of the gun battle. It is naturally very clear how serious the incident was yesterday. It is no exaggeration to say that this has risen to the height of national security.
So after he heard the words, he said without hesitation: "No problem! Let's go now, I am asking the leader on the road!"
......
Half an hour later, the group came to the city public security bureau command center.
Guo Zhan only took Xia Ruofei and Tian Feilong into the team, and the other players were on the bus.
The command center of the Municipal Public Security Bureau is a hall of thousands of square meters. 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.
Police officer Li has reported the situation on the road. Therefore, when Xia Ruofei came to the command center, the deputy director of the Public Security Bureau in charge of criminal investigation personally received them.
This is also the Secretary Chen Bo did not know that there are even Xia Ruofei in the military, otherwise he will definitely meet in person.
Deputy Director Lu and Guo Zhan shook hands and said: "Colonel Guo, we have already watched the surveillance screen near the north gate of Sanshan University at five o'clock yesterday, and found the van."
The name of the Lone Wolf Commando was top secret, so the military did not inform Guo Zhan’s position, but only informed him that his rank was Colonel.
Guo Zhan immediately said: "Can Director Lu analyze the trajectory of this car?"
"Our technicians are conducting an analysis, and it should be a problem." Deputy Director Lu said, "Several people here!"
As the capital city of the developed provinces in the eastern part of China, Sanshan is also in the forefront of the country. The construction of Tianwang project in Sanshan City started relatively early, and the hardware and software facilities are clearly ahead of the cities in some less developed provinces.
Now Tianshan City Public Security Bureau's Skynet system can use the license plate number recognition function to add time and other algorithms to the image returned by the massive camera of the city, and automatically calculate the approximate driving trajectory of a certain vehicle.
In addition, as the number of high-definition cameras continues to increase, the face recognition function is constantly improving.
The role of Skynet in the public security organs is also growing.
Before everyone came to the big screen, Deputy Director Lu gave a gesture to the technicians who were operating the computer.
A large area of ​​the center of the big screen immediately showed a monitoring picture, which was taken by a security probe at the north gate of Sanshan University.
I saw that the white van was slowly coming out from the north gate. After going out, I turned right and sailed on the sail road.
Until the car disappeared into the surveillance range, the picture immediately moved to the scope of another probe, and the van quickly appeared in the scope of the probe.
On the right side of the big screen is a map with a red line starting 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't achieve global coverage. The car will always enter the monitoring blind zone, and then it may take a while to appear in another monitoring area. In the blind zone, the trajectory of the car can only be comprehensively analyzed by factors such as time difference, vehicle speed and the next position.
This line represents the red line of the van's trajectory all the way to the north.
Tian Feilong said with a slight brow: "Did they really hide in the mountains?"
Xia Ruofei said calmly: "The possibility is not big. After the incident, our reaction is still very fast. In addition, the traffic volume in the urban area was very large during that time. At this time, the direction of the city should have been controlled. They took Professor Liang to succeed. The possibility is small."
Guo Zhan also nodded and said: "I agree with the opinion of if flying."
Sure enough, after a while, the red line was stopped when it was near the Xinyuan Road in the urban-rural junction of Sanshan City.
The police in charge of the technology said: "The target disappears here, and then it does not appear in any of the city's monitoring probes."
Deputy Director Lu immediately said: "I will immediately demarcate the area and send people to investigate in the past!"
"Yes!" said the policeman in charge of technology.
The distribution of monitoring probes in the urban-rural junction is not as dense as in the urban area. There are some monitoring dead angles. Soon the system draws out several areas in the vicinity according to the last position of the van.
The truck may only be parked in those areas, otherwise it will be photographed by other probes.
A large number of police forces quickly dispatched.
Tian Feilong asked: "Summer class leader, do you want to bring Xiaohei to follow the police?"
Xia Ruofei said: "I feel that even if I find a truck, it is unlikely that I will get further clues. I still have to go."
After that, Xia Ruofei turned his attention to Guo Zhan.
When Guo’s strategy sank, he nodded slightly.
Soon, Xia Ruofei joined Tian Feilong with a black car and boarded a police car to go to several areas just scheduled to investigate.
Guo Zhan is in the command center of the Public Security Bureau.
With the auxiliary analysis of the Skynet system, the scope of the investigation is not large, and there is no suspense in finding the car.
Sure enough, Xia Ruofei, when the car had not arrived at the destination, there was another small team news in the intercom, they had found the van.
So Xia Ruofei, their team also immediately diverted, went directly to the location of the van.
This is an abandoned mechanical processing plant in the northern suburbs of the city. The white van is parked in the weedy yard of the factory.
This area is a blind spot for monitoring.
Xia Ruofei got out of the car and immediately ran to the van with the black. The police had already ordered the full cooperation, so it did not stop Xia Ruofei and Xiao Hei.
After opening the rear compartment, Xia Ruofei patted the black head, and Xiao Hei rushed up like a lightning bolt.
It sniffed around inside the compartment, Xia Ruofei asked: "Little black, is there the smell you just smelled in the car?"
Xiao Hei immediately called Wang Wang twice, and then nodded very humanly.
Although the group used this car to sneak into the campus, and then the teacher Zhang held the matter has been basically confirmed, but after getting a positive answer from Xiaohei, Xia Ruofei is still a little excited.
Now it is 100% sure!
Xia Ruofei quickly waved to the black and let it get off.
"Little black, you sniff around here and see if you can find the smell just now?" Xia Ruofei said.
Xiao He immediately sniffed around the van, and after a long while, it shook his head at Xia Ruofei with great frustration.
The police also feel very fresh about Xiao He's humanity, but their attention is more focused on clues.
Seeing that Xiaohei did not find any clues, the police officer who led the team could not help but ask: "Do you need us to adjust the police dog?"
Tian Feilong said with a smile: "The little black is much more powerful than the police dog. Yesterday, the police officers of the special police team did not find any clues. However, today, the black horses have dug out this clue hard! So you can't use the police dog. of."
"How come there is no smell left?" Police officer Wang said inexplicably. "There are residual smells in the car!"
Xia Ruofei and Tian Feilong looked at each other and said in unison: "They changed cars!"
Xia Ruofei said: "Go! Let's go back to the command center!"
Xia Ruofei thought and said: "Wang police officer, please leave a few comrades to check this car to see if there are any clues left! Feilong, immediately contact the Wolf King with a secret mobile phone, let the comrades of the command center use the day The network system conducts in-depth analysis, and divides the monitoring blind areas along the way into chronological order to see which blind areas can make them change their cars!"
"Understand!" Wang police officer and Tian Feilong said at the same time.
Xia Ruofei glanced deeply at the van and said, "Let's go! Since we have caught this clue, they will not run!"
