Lu Weiwei said you're welcome and walked out of the door directly.
He Junchao stretched out his waist, made a babbling noise, and then stood up, preparing to follow everyone to the canteen to eat together.
But Gu Chen immediately stopped him and said, "Senior Brother He, please help me bring out the surveillance footage of Wang Xinyu after he left our police station and take a look at it again."
"Okay." He Junchao didn't hesitate. After taking a few steps, he immediately turned back and opened the files on the computer for Gu Chen.
Then he introduced to Gu Chen: "It's all here, you can see for yourself."
"Thank you." Gu Chen stood up and came to He Junchao's seat.
He Junchao, on the other hand, touched his growling stomach and left the office directly.
At this moment, in the huge office, only Gu Chen was sitting on He Junchao's seat, watching the surveillance camera quietly.
This time, Gu Chen did not browse the surveillance content quickly like before, but slowly observed it at the speed of an ordinary person.
It can be said that Gu Chen is looking for clues frame by frame.
Ever since Wang Xinyu left the police station, Gu Chen started patrol mode.
I saw Wang Xinyu getting into a taxi and arriving at one of the locations. Here, Wang Xinyu stayed for half a minute, and then asked the driver to leave the scene.
Gu Chen took out a pen and paper, marked the location, and whispered:
"Jiangbin East Road, the parking location is at the entrance of a calligraphy and painting store."
After writing these on the manuscript paper, Gu Chen observed the surrounding situation again. After finding that there were no suspicious people around, Gu Chen clicked the play button again.
At this time, the taxi was still driving normally, and Gu Chen was also patrolling along the way.
The location where Wang Xinyu parked his car for the second time was on Nanyuan North Road. Gu Chen wrote down the location and looked at the store in front of him. It was a small shop selling sesame cakes.
Based on his previous observation habits, Gu Chen used surveillance to investigate suspicious people around him.
In order to make the investigation more accurate, Gu Chen even started to investigate the surrounding people before Wang Xinyu came to Nanyuan North Road.
However, what made Gu Chen a little disappointed was that all the pedestrians around him were normal and there were no so-called suspicious persons.
"This is the cunning point of Wang Xinyu. Did she stop the car at random to get rid of our police's tracking?"
Gu Chen thought for a moment and shook his head in denial: "No, doesn't she know that our police can clearly trace her driving route through surrounding surveillance?"
"What she did was actually a useless effort. If she wanted to get away from the sight of our police from the beginning, it would obviously be unrealistic."
"Wang Xinyu himself also disappeared at the last location, which is the real surveillance blind spot."
"It can be seen that Wang Xinyu has actually investigated the surrounding routes long ago, and the area where she finally disappeared is where she escaped from our police surveillance."
Taking a deep breath, Gu Chen lay back on his seat and continued to think about the problem:
"But that's not right. She could obviously escape from the police's sight through the blind spot, so why did she have to turn left and right in these unfavorable areas and park at random."
"What is Wang Xinyu doing? Is it to connect with others? Or is there another purpose?"
"If Wang Xinyu wants to contact someone, where is the contact person? Why didn't I find out?"
"Or is there something she wants to tell me? After all, Wang Xinyu is very smart, and there must be a reason why she does what she does."
Thinking that he could not solve the mystery of Wang Xinyu's evacuation route, Gu Chen simply continued to investigate.
The surveillance screen was used to locate Wang Xinyu’s driving route again.
After randomly shuttling on the road, or rather aimlessly, Wang Xinyu's taxi stopped at Shifu Road again.
Gu Chen observed carefully this time and found that the roadside where the car was parked was an advertising company.
Gu Chen followed the old rules and continued to investigate the surrounding situation, but still found no trace.
With no choice but to do so, Gu Chen also shook his head, feeling that Wang Xinyu's strange behavior of parking the car so casually would give the police a huge headache in their investigation.
The key is that these locations seem to be random parking spots for Wang Xinyu.
Moreover, according to the previous investigation of the taxi driver, it was found that the female passenger that day seemed to have made random requests without any purpose.
If it weren't for the fact that the route Wang Xinyu was going to take was a bit long, allowing the taxi driver to make a small fortune, the taxi driver wouldn't want to be tossed back and forth by Wang Xinyu like this.
With a sigh, Gu Chen felt a little helpless, so he continued to follow the surveillance.
Wang Xinyu's next parking spot was on Keke Middle Road, next to a car maintenance store.
Gu Chen still didn't find the suspicious person, so with a fight to the end, Gu Chen continued to monitor and track.
This time, Wang Xinyu's driving route was a bit long. He stopped on a small road next to a technical school. Gu Chen took a look and found that the location was on Jiugong South Road. There was no storefront at the door, only a cultural promotion wall.
In order to investigate carefully, Gu Chen specially used his master-level observation skills to briefly check the contents of the cultural wall through the surveillance perspective.
"They are all old-fashioned slogans and some unremarkable wall paintings. There is not much doubt."
Gu Chen shook his head, a little frustrated, but still had enough patience to continue investigating the surrounding situation.
Gu Chen obtained information about the ten minutes before and after Wang Xinyu parked his car and arrived here. However, the conditions of passers-by were normal and there were no suspicious persons.
At this moment, Wang Xinyu's location had already reached the outskirts of the city.
There are some technical schools scattered here, and there are also urban villages around it.
In these locations, monitoring is difficult to cover as many plots are being developed and renovated.
This is why Wang Xinyu finally got off the car in the surveillance blind spot and then disappeared.
It can be seen that Wang Xinyu has thought about his escape route.
"Junior Brother Gu, are you hungry?" Seeing that Gu Chen was still working hard, Lu Weiwei had packed the food and packed it in a lunch box, and walked directly to Gu Chen and put down the lunch box.
"Senior Sister Lu is very fast, isn't she?" Gu Chen also said casually, but kept his eyes fixed on the monitoring screen.
Lu Weiwei grinned, opened the disposable chopsticks with her mouth, then quickly opened the lunch box, brought it to Gu Chen and said:
"What's so fast? There aren't many colleagues eating in the canteen at night, but it also took a long time."
"Xiao Yuan and Lao Wang also want to bring them back to eat. I asked them to stay in the cafeteria and don't have to come over."
While talking, Lu Weiwei had already put her own food and Gu Chen's food separately.
Because she was so hungry, Lu Weiwei was not restrained and just started eating on her own.
You can see that Gu Chen is still working, so while eating the food, he reminds Gu Chen:
"Junior Brother Gu, it's important to eat, otherwise the food will get cold. It's okay to continue working after eating."
"Got it." Gu Chen nodded and wrote the last parking location of Wang Xinyu on the scratch paper.
Lu Weiwei stretched her neck and read softly according to the words written by Gu Chen:
"Pipeline construction? Why do you remember this?"
"This is where Wang Xinyu parked his car." After finishing writing, Gu Chen put down his pen, then picked up his food and started to enjoy it.
Lu Weiwei couldn't help but curiously asked: "But the locations you wrote before seemed to be on a certain road. Why did you write 'pipeline construction' in the last one?"
"Because the last road seems to be an unknown road. I checked it online and it hasn't been officially named yet."
"And because where Wang Xinyu parked his car, there was a work sign saying 'Pipeline Construction' next to it, so I just wrote it down casually."
"Well, it's interesting." Although she felt that Gu Chen's investigation was somewhat serious, it was difficult for Lu Weiwei to understand why Wang Xinyu had to go around in circles, stop and go, and finally disappear in the blind spot of the surveillance.
While Gu Chen was eating, he couldn't help but said: "This is the place where Wang Xinyu parked his car for the last time."
"After she came out of our police station and took a taxi to leave, she stopped a total of 6 times within the surveillance area, and each time she stopped for half a minute."
"That's right." Lu Weiwei nodded in agreement while eating her food:
"This has been investigated before and was confirmed by the taxi driver."
"But I just don't know what the purpose of her doing this is. After all, the route she took and the area where she parked seemed random."
"Even the taxi driver thought she was just walking around randomly with no purpose."
"I don't understand." After hearing what Lu Weiwei said, Gu Chen also smiled bitterly and began to eat faster.
Lu Weiwei was the first to start and finish the meal. After throwing the empty lunch box into the trash can in the office, she walked directly to Gu Chen.
He casually took Gu Chen's record in his hand and looked at it carefully.
Gu Chen recorded it in great detail, including the time and place, where he stayed, and what stores were nearby? These are all recorded in detail.
From top to bottom, 6 locations were recorded, so Lu Weiwei couldn't help but read out according to the order Gu Chen recorded:
"Jiangbin East Road, Nanyuan North Road, Shifu Road, Keji Middle Road, Jiggong South Road, pipeline construction."
After thinking for a while, Lu Weiwei raised her head and thought: "Are these places related to Wang Xinyu? Or does she want to remind us of some clues through these roads?"
As soon as Lu Weiwei finished speaking, Gu Chen on the other side suddenly stopped eating.
When Lu Weiwei saw this, she was also curious and said: "Junior Brother Gu, what's wrong? Is the food not delicious?"
"No." Gu Chen put down the lunch box, his eyes lit up, and he said quickly:
"Senior Sister Lu, you just said that these roads may be clues that Wang Xinyu deliberately left for us?"
"Yes, it should be possible, right?" Lu Weiwei wasn't very sure either.
So Gu Chen quickly picked up his records and checked them again.
After a moment, Gu Chen's eyes lit up and he said with a cheerful smile: "Yes, why didn't I think of it? In fact, Wang Xinyu had her own little calculations when parking at these places. Why didn't I think of it before?"
"Gu...Junior Brother Gu, what are you thinking of?" Seeing Gu Chen so happy, Lu Weiwei felt baffled.
Gu Chen didn't hide it, he directly circled his records, especially the parking roads, with a pen, showed them in front of Lu Weiwei and said:
"Senior Sister Lu, look, where are these places?"
"Jiangbin East Road, Nanyuan North Road, Shifu Road, Keji Middle Road, Jigong South Road, pipeline construction." Lu Weiwei read out from top to bottom, then raised her head and asked Gu Chen:
"Is there anything wrong with this?"
"Of course it's okay to read them separately, but if this is an acrostic poem, where do you think it should be?" Gu Chen continued to prompt frantically.
Lu Weiwei's eyes lit up and she was stunned. She quickly picked up the manuscript paper in her hand and continued to read out according to Gu Chen's so-called acrostic poem prompts:
"Jiang Nan City Science and Technology...Management?"
After a pause, Lu Weiwei's eyes suddenly froze, and she blurted out: "Jiangnan Science and Technology Museum?"
"That's right." Gu Chen nodded fiercely and said involuntarily:
"The location Wang Xinyu wants to tell us is the Jiangnan Science and Technology Museum."
"There was no road sign next to the location where she finally stopped, but there was a work sign warning of 'pipeline construction'."
"Combined with the fact that every time Wang Xinyu parks her car, there is a street sign next to it."
"I concluded that this was Wang Xinyu's reminder. Everything she wanted to tell us was written on the road signs."
