Xia Ruofei didn't expect the enemy to switch vehicles midway, so he wasn't too disappointed. If this group of people didn't even know such a simple anti-tracking method, they wouldn't have been sent to Huaxia to carry out this mission.
However, after Xiao Hei successfully tracked down the scent left on Professor Liang's body, they finally found a lead in the messy search. Now that the perimeter was under high pressure, it would be extremely difficult for the group of people to escape.
Xia Ruofei and Tian Feilong returned to the command center in a police car.
On the way, Tian Feilong reported the situation to Guo Zhan through a confidential phone. The command center also quickly used the Skynet system to analyze the blind spots of the van's entire driving trajectory.
When Xia Ruofei returned to the command center, the technicians of the Public Security Bureau were working hard.
After all, Tian Feilong couldn't report in too much detail over the phone, so Xia Ruofei told Guo Zhan about the investigation at the scene, then asked, "How's the analysis going?"
"The amount of data is a bit large, so it might take some time," Guo Zhan said.
The Skynet system wasn't omnipotent. After all, there were at least a dozen blind spots when the van traveled from Tri-Mountain University to the abandoned factory in the northern suburbs of the city.
Some of the blind spots appeared in the next surveillance area in just a few seconds. Excluding the time it took for the van to drive, the possibility of the person switching vehicles during this time was basically non-existent. These could be ruled out first.
As long as the blind spots stayed for a long time, further analysis would be needed.
This involved the analysis of the new vehicles that appeared in the blind spots at the same time. Their driving trajectories had to be analyzed and ruled out one by one.
It was like a huge tree structure at the bottom, so the amount of data needed to be analyzed at the same time was enormous.
Of course, if they relied on manual inspection, the time it would take was immeasurable. It was basically an impossible task.
Therefore, Xia Ruofei and the others could only wait.
They waited for more than two hours, and it was already past lunchtime. The Public Security Bureau wanted to invite Guo Zhan and the others to the cafeteria for lunch, but Xia Ruofei and the others weren't in the mood to eat, so they had no choice but to ask the cafeteria to pack some lunches and send them to the command center. Everyone made do with a meal.
At around 1: 30 in the afternoon, the huge amount of data analysis was finally completed.
The system screened out a dozen suspicious vehicles, all of which were matched in terms of time and driving trajectories. Every one of them could be a vehicle that the group of people switched vehicles after leaving the van.
Next, they could only do manual inspection.
Deputy Director Lu began to personally assign tasks. After some thought, Guo Zhan said, "Director Lu, considering that these people are all armed, I suggest we ask the armed police to cooperate with us. Comrades, please be careful!"
"Okay, I'll immediately ask the higher-ups to coordinate with the comrades of the armed police detachment to come and support!" Deputy Director Lu said.
Xia Ruofei pondered for a moment and said, "Wolf King, I think we should let Blackie participate in this operation. We have to consider the possibility of this group of people splitting up. With Xiao Hei around, we can keep an eye on Professor Liang's car! "
. '' ''s's's's.' ''s's's's't.. a''s. I also need you for my intelligence analysis! "
Guo Zhan could already feel that after Xia Ruofei retired from the military, not only did his professional abilities not deteriorate, but they seemed to have improved tremendously. In this operation, the ability he displayed was even stronger than Tian Feilong, who specialized in intelligence analysis and trace inspection.
Xia Ruofei thought for a moment and said, "I'll tell Xiao Hei to cooperate with the police! I won't go myself. "
"Will it work?" Guo Zhan was a little uncertain.
Xia Ruofei smiled and said, "Don't worry! Little Black is very smart! "
After that, Xia Ruofei asked Deputy Bureau Chief Lu to designate a police officer who had experience with dogs. He then whispered a few words to Little Hei. Little Hei immediately wagged his tail at the police officer and walked over obediently.
"Deputy Director Lu, we have to get Little Black to confirm all the vehicles that we can't eliminate as suspects. It remembers the scent of the hostages." Xia Ruofei said seriously.
"No problem! '' Deputy Director Lu said.
The police officer took Little Hei and left the command center. Xia Ruofei and Guo Zhan waited for news in the command center.
Soon, messages came back one by one.
Most of the messages were invalid.
Some of the vehicles were owned by the company and were installed with the GpS system. They directly accessed the driving data records, including the speed, trajectory, and so on. Combined with the monitoring blind spots, it was easy to eliminate them.
Some of the vehicles, after being confirmed by Little Hei, did not have Professor Liang's scent at all. Even if the group of people split up and took this vehicle, they were not the focus of the tracking.
Although the messages were invalid, they were not useless. As the vehicles were eliminated one by one, Xia Ruofei and his team were getting closer to the truth.
Then, another message came.
Officer Wang, who had stayed at the abandoned machinery processing plant, extracted a fresh fingerprint from the van's steering wheel.
Coincidentally, this fingerprint was recorded in the police's fingerprint database because the owner of the fingerprint was a person who had been released from prison.
The police soon found the home of the man named Liu Jun. His wife said that Liu Jun had not been home for two days. Before leaving the day before yesterday, he was very happy, saying that he had a big business deal and would come back to buy new clothes for them. However, he never came back.
Xia Ruofei sighed and said, "Needless to say, this Liu Jun has most likely been killed. Pay more attention to John Doe's body in the next two days … "
Deputy Bureau Chief Lu nodded in agreement.
The results of the portrait identification soon came. The driver yesterday was Liu Jun, who had been released from prison. At the time, there was another person sitting in the passenger seat. The police compared a lot of data but did not find anything.
However, the military intelligence department made new progress.
After receiving a few screenshots from the confidential network, they quickly compared them in the internal database.
The result was an unexpected surprise. The middle-aged man in the passenger seat was confirmed to be Kappei Yamai, a member of the elite spy organization Kawano Group, under the intelligence headquarters of the Japanese Ministry of Defense.
Of course, such information was not in the police database. The military had its own sources of information, and many members of the spy organizations were actually registered in the database.
Guo Zhan's face was livid. He punched the table hard and said, "They are really the goddamn Japanese! I'm going to find these bastards one by one and skin them alive! "
Guo Zhan's grandfather was a hero against the Japanese. He had participated in the bitter eight-year war. His hatred for the Japanese had been in his blood.
This time, new hatred had been added. The old Captain Luo had died under the guns of the Japanese agents. Guo Zhan was already furious.
Tian Feilong frowned and said, "Since Kappei Yamai has been registered in the military intelligence database, he should have been targeted when he entered the country! But we didn't receive any information at all! "
Xia Ruofei said indifferently, "These people aren't fools. They knew that their identities might have been exposed long ago, so I concluded that they came in through illegal means, so it's impossible for them to have left any records."
Guo Zhan gradually calmed down and nodded. "Yes, and they may have planned the escape route from the beginning. Now it seems that the possibility of this group of Japanese escaping through the sea is higher!"
The police also sent out a small team to continue the inspection and verification of the vehicles.
After an intense inspection, the suspects of the vehicles were ruled out one by one. In the end, there were only two vehicles left.
The two vehicles had one thing in common. They had been parked on the route of the van for a long time, in two different blind spots.
After the van passed by, the two vehicles appeared at the intersection in different directions.
The van had been parked in these two blind spots for about half a minute. As long as the speed of the van changed slightly, it was completely possible to complete the change of vehicle.
What was more coincidental was that the two vehicles were nowhere to be found. The police repeatedly checked the area where the vehicles had disappeared, but they couldn't find a trace of the two vehicles. It was obvious that they had been deliberately hidden.
If they had deliberately found a blind spot and parked the vehicles in a garage or in a shop, the police wouldn't have been able to find them in a short time.
Xia Ruofei looked at the two red tracks on the big screen and pondered.
There were two screens next to the tracks, playing the surveillance footage of the two vehicles in a loop. The Skynet system automatically spliced the footage from each camera.
The two vehicles' destinations and driving routes were different, but the general direction was basically the same. They were both driving in the direction of Changping County, which was near the sea.
Guo Zhan frowned and said, "It seems that they have chosen to escape through the sea!"
"Yes! The possibility is very high, "Xia Ruofei said with a dignified expression.
Guo Zhan shook his head and said, "That doesn't make sense! After the incident that day, we immediately coordinated with the relevant military departments and set up surveillance at all the exits of the city. The two vehicles have both left the city … "
Xia Ruofei frowned and stared at the two vehicles on the screen.
One of them was a black Honda sedan. The last place it disappeared was near Gaoqiao Town in Changping County.
The other was a blue Buick MPV. The Skynet system tracked it to the vicinity of Port Town and then it disappeared.
This location wasn't far from Xia Ruofei's Taoyuan Farm.
Xia Ruofei's gaze fell on the blue Buick MPV. In the surveillance footage, the car was passing through a flooded road.
"Pause the footage on the right!" Xia Ruofei suddenly shouted.
The policeman in charge of technical support immediately pressed the mouse and paused the footage.
"Ruofei, did you find anything?" Guo Zhan asked with concern.
Xia Ruofei frowned slightly and pointed at the Buick MPV on the screen. "Does anyone feel that this car is a bit strange? It seems to be very heavy. Let's rewind the footage and compare it with the car next to it … "
The policeman immediately operated the computer to rewind the footage and continued to play it.
Sure enough, compared to the other cars, this MPV seemed to be very heavy. When it passed through the puddles, there was clearly a heavy drop.
In front of this car, there was a similar MPV passing by, but it seemed very light.
Deputy Director Lu asked, "Could it be because this car is full?"
Xia Ruofei shook his head and said, "There shouldn't be such a big difference."
After Xia Ruofei had been strengthened by the Spirit Nourishing Soup and Body Tempering Soup, his eyesight had long surpassed that of ordinary people. Therefore, he very keenly sensed that there was something wrong with this car.
"What could be the reason?" Guo Zhan asked thoughtfully.
"I think there are two reasons. First, as Director Lu said just now, the car is full, and these people are carrying guns and ammunition, so the car itself is relatively heavy. " Speaking of this, Xia Ruofei paused and continued, "Second, this car is very likely to have been modified to make it heavier than before!"
Guo Zhan's mind flashed, and he said loudly, "Ruofei, you mean … Professor Liang is very likely to have been hidden in a modified hidden space in the car?"
"Yes!" Xia Ruofei said. "These people are all new faces, and the main target of the police's check is Professor Liang. As long as Professor Liang is well hidden, it's easy for them to get away with it. The chassis of this car is very likely to have undergone major surgery, and Professor Liang is hidden in it! "
"In other words …" Guo Zhan said with a dignified look, "This group of Japanese people is very likely to have taken Professor Liang hostage and jumped out of the encirclement we set at the intersection of the city?"
Tian Feilong asked worriedly, "Could they have already gone out to sea? If so, it would be difficult for us to catch them … "
Xia Ruofei calmly analyzed, "This is possible, but not likely. First of all, our patrols in the coastal areas are very dense, and all the villages and towns have been notified to be on high alert. Those people who are trying to smuggle people out of the country wouldn't dare to commit crimes at this time, so it would be better for them to find a place to hide and wait for the news to die down before leaving. "
"They could have modified the boat and taken Professor Liang out of Huaxia without anyone noticing!" Tian Feilong said.
Xia Ruofei smiled and said, "Don't forget that there are maritime police, public security border guards, and comrades from the navy patrolling the sea. This group of Japanese people knows that they may have been registered in the military, so they wouldn't dare to take this risk. Yesterday's incident was very sudden, and the people who set up the checkpoint were mainly the public security police. They were confident that we wouldn't be able to find too many clues in a short time, so they dared to leave the city. "
Guo Zhan, Deputy Director Lu, and the others nodded slightly, thinking that Xia Ruofei's analysis was very reasonable.
Xia Ruofei continued, "There's one more thing. Let's think about it from the Japanese's point of view. They want the experiment data, and the core data is hidden in a secret place by Professor Liang. At this time, even if Professor Liang gives in and is willing to cooperate with them, what if Professor Liang can't repeat the experiment? After all, the human brain isn't a computer. I don't think Professor Liang can remember all the core data in his mind, right? "
Guo Zhan nodded and said, "So, they just want to find a safe place to force the location of the core data out of him, and then take the data away!"
"Yes, I think they won't leave so easily before they get the core data," Xia Ruofei said. "After all, it's not easy to sneak into Huaxia, and it'll be difficult to come back in after they leave. Changping County is right by the sea. Once they get the data, the situation won't be so tense. They can easily use the smuggling boat to escape to the high seas, and then take the receiving boat to return to Japan! "
Xia Ruofei's analysis was reasonable. Guo Zhan, Tian Feilong, and the others all nodded, thinking that this was the closest analysis to the truth.
