"Last night at ten o'clock, Chen Yuanliang claimed that he had something to go out to discuss with an old friend, and he took a taxi away by himself. At eleven o'clock that night, his wife called, but Chen Yuanliang didn't answer. He called again at eleven thirty, but he still didn't answer, but he replied. The news said that if there is something to delay, I will go back later; near twelve o'clock, the prompt tone said that the other party has been turned off, and I have not contacted the master since then."
Bu Chonghua pushed open the office door of the Criminal Investigation Detachment, and asked without turning his head, "Has the location of the phone's last exchange of signals with the base station been found?"
"I found it. It was near the fertilizer factory in the suburbs at 11:35 last night. There has been no result since then."
"Let the technical team try to do a more precise positioning, and each unit will issue a notice of assistance to Chen Yuanliang!"
"Yes!" Cai Lin ran away.
Yan Yun has been tracking down Qin Chuan's whereabouts, and finally found a clue and rushed over excitedly, but the ten million luxury car was slammed into half of the buttocks by his cousin, and his mood was straight down; then he saw Wu Yu next to his cousin, He was quite a friendly person, and when he saw his cousin, he felt even more affectionate, and a little relief and a little happiness rose again; who would have not been happy for a few minutes, and then learned that the old man Chen Yuanliang had disappeared. Back at the bottom of the valley, I only feel that life really is ups and downs...
The three of them had no choice but to rush back to the Nancheng Branch. Bu Chonghua didn't even enter the office door, so he took Wu Yu and rushed into the field team to urgently command the entire city to search and issue a notice of assistance.
Yan Yan has no jurisdiction, so he can only lie in the office of the criminal investigation detachment chief, holding a mobile phone and chatting on the phone with his lover who is suspected of "P issued a graduation certificate from OUHK": "Hey, daughter-in-law, we have lunch at noon. Hey, what did you eat? The new combat instructor from your police academy didn't secretly send you little pink flowers today... Don't worry, I've already memorized those two notebooks, don't worry, I'll take this stubborn exam. Can we not go there once... What, do you have any news about the grandson who ruined our wedding? Don't worry, I will let you know as soon as I catch him. You want to hang him with braised, steamed, fried, and dripping wax and smoke it. Eighteen times no problem!…”
Yan Xun put her thighs on two legs. After 20 minutes of chattering, she finally hung up the phone with a face full of tenderness and sweetness. Then she looked up, full of anger on her face:
"Did I say that your Nancheng Detachment was cursed by the Africans?!"
It happened that Bu Chonghua and Wu Yu pushed in the door, turned around and left without saying a word.
Yan Yan was gloomy: "Mike..."
With two swoops, Bu Chonghua and Wu Yu froze at the same time, as if being cast on a spell worth eight figures.
Yan Yan looked at them back and forth dissatisfied: "Is there any news about Chen Yuanliang?"
"No," Bu Chonghua said coldly, "a tracing notice has been sent to various airports, ports, railway stations, and highway entrances and exits, but the situation is not optimistic. Even if a seventy-year-old man wants to run away, he will not He was alone in the middle of the night, and from the surveillance video, he didn't bring any change of clothes, and it didn't look like he was hiding a lot of cash. I'm more inclined that he might actually go to meet someone, and then encountered ... some kind of accident."
Yan Xun stared at his cousin for a long time, and after a while he spat out a few words: "Aren't you going to review yourself?!"
Bu Chonghua: "..."
"Look at the recent case of your Nancheng Detachment, ah - it took a lot of effort to find Gao Ling, but Gao Ling not only disappeared, but also became a giant concept; As a result, Gao Baokang not only disappeared, but only got his two legs back; your cousin crashed an SLR to give you clues, and Chen Yuanliang disappeared for me after a mere afternoon tea! Why did the repeated Mercury retrograde incidents never arouse your vigilance, Captain of the Regiment?!”
"...That," Wu Yu raised his hand to touch his nose, and defended weakly: "Chen Yuanliang was released after the forty-eight-hour detention period, and it has nothing to do with the Bu detachment..."
"Why doesn't it matter!" Yan Yan said angrily, "I just saw it, the only one in the entire detachment is his phone if there is no talisman posted under it!"
Wu Yu: "...?"
Wu Yu's expression was blank, he watched Yan Yu open his phone case, and took out a small piece of paper. He pressed his face under his phone with an expressionless face.
"Learn from your technical detachment upstairs and raise a few goldfish in the whole fish tank, do you understand?" Yan Yan frowned.
Bu Chonghua: "Okay, I know."
"… I believe that karma is a kind of man-made, feng shui theory is a coincidence of geography, psychology, and group effects... "
"All the farce directed by ghosts and gods, behind the curtain are full of fingerprints of criminals..."
Wu Yu finally realized that it was really just a high-level B installed by the academic leaders in front of him. The last atheist in the Nancheng Branch finally showed a prototype in front of the water retrograde.
·
Grandpa Song Ci probably didn't like that he was suddenly moved from the latest kidney machine to the landline phone, so that in the first few hours, he did not make any contributions to bless the battered Nancheng Detachment.
The feedback from the airport, station, highway, etc., did not find any trace of Chen Yuanliang, nor did the surveillance capture the complete license plate of the taxi he left home last night. Until eight o'clock in the evening, the investigation of the city's taxi companies continued, but there was no clue of Chen Yuanliang in the vast crowd.
Time passed minute by minute, and some kind of sinister omen exuded a gloomy atmosphere in the dark.
At 8:30, the inspection and monitoring room.
"All the surveillance cameras transferred by the traffic control bureau are here, now." Wang Jiuling looked dissatisfied with being caught back to work overtime on Sunday night: "But it is very difficult to find that taxi in the city center with the busiest nightlife at ten o'clock in the evening. It's no less than looking for a needle in a haystack, I advise you to think of another way, otherwise you won't be able to find the bad old man surnamed Chen if you stare at the entire inspection team."
Bu Chonghua stood behind Director Wang's chair, his sword brows clenched and he didn't say anything. In the surveillance video, Chen Yuanliang's staggering back appeared in the lower right corner. He lowered his head and got into a taxi whose license plate could not be seen clearly, and disappeared after a few seconds. Monitor the corner.
"What do you think?" Wang Jiuling couldn't help but asked.
"The eight major taxi companies in Jinhai operate a total of 30,000 taxis, with 6,000 individual business licenses, uniformly painted with blue, blue and white stripes. Ninety percent of the 36,000 taxis are Toyota Corolla and FAW. Weizhi, the only difference is the dome light plate. Among them, there are four kinds of dome light plates that are very similar to the car on Chen Yuanliang. Combining the operating hours, driving sections, and registration information, the number of taxis we need to check should be 4,440. A hundred or so."
Bu Chonghua's voice was steady and clear, but Wang Jiuling's head was loud for a while. She couldn't help scratching her sparse scalp with a ballpoint pen, and tapped on the screen with the tip of the pen, saying, "Look, this car is half-new and not old. look like…”
Whoosh!
Bu Chonghua took out a tissue and wiped it carefully on the screen where the ballpoint pen had just tapped.
The air froze.
"..." Wang Jiuling narrowed her eyes, and her eyes flashed with a dangerous gentleness before the storm: "Bu detachment."
"Well."
"I suddenly remembered something, Xiao Gui told me that there was a rumor circulating in the Criminal Investigation Detachment recently that someone spread the rumor behind my back that baldness was caused by a virus, and it would be transmitted through eyes and breathing..."
Bu Chonghua said lightly, "How come? There is no such virus in the world."
"Then may I ask you this?"
"Obsessive-compulsive disorder."
Director Wang was full of suspicion, but Bu Zhonghua's handsome and indifferent face did not change in the slightest. At this moment, he heard "Yo!" from behind. Yan Yan walked into the door eating the last piece of ham, and threw the skin into the trash. He picked up the tissue on the table that had just wiped the screen and wiped it on his mouth: "How are you guys, is there any progress in the search... Hey!"
Bu Chonghua grabbed his cousin's hand like lightning and grabbed the tissue: "Be careful!"
Yan Yan: "?"
"That rumor was really made by you!" Wang Jiuling raised the table and said angrily, "It's too much Bu Chonghua! I'm going to the procuratorate to sue you!"
Director Wang graduated from the local TOP Medical University in Jinhai, and worked well in the hospital in his early years. He is known as Wang Shaoxia. Later, Wang Shaoxia's reputation spread far and wide, and he often became the main target of professional medical troubles. In the end, he was overwhelmed and had no choice but to change jobs. Soon after the job-hopping, Director Xu Zuxin was tempted by the allocation of housing, the work of his lover, and the school of his children, and he was hooked to the Nancheng Branch. The technical detachment later found that the forensic room is really a good place for patients to be well-behaved and lovely, so they worked in peace for 20 years, and have never been troubled by doctor-patient disputes in their life.
Even so, Wang Shaoxia's attack power in the past was still amazing, he almost put the wig cover on top of Chonghua's head, but was hurriedly pulled by Yan Yan and pressed back on the back of the chair: "Don't care about this child, you have not respected your old love since you were young. Young, I will teach him a lesson when I get home... Sit down, don't be angry, in two years he will understand the helplessness and sadness of our older generation."
Wang Jiuling looked at the top of Yan Yan's bushy head, and a glimmer of hope rose in her heart: "Could it be that you are also..." Wig cover
"Oh that's not true." Yan Yan said, "but I lost three whole hairs when I combed my hair this morning. I'm so angry, it must be the reason why the north is too dry and not acclimatized."
Director Wang: "..."
Director Wang raised the table again, and said with grief and indignation, "You two brothers should get out of the technical team after watching the surveillance!"
The brothers leaned back at the same time, lest they be sprayed by spit stars with bald virus.
·
"That one, look, it's that one—eight figures!"
"Mom-"
"How many lifetimes will I have to work overtime without food or drink to afford this car?"
"Excuse me, I'm sorry..."
In the large office of the Criminal Investigation Detachment, a bunch of criminal policemen huddled their heads in front of the window, scrambling to watch the small black Mercedes-Benz sports car with half a shriveled rear wing in the open space downstairs. There was a majestic: "cough!"
As soon as Cai Lin turned his head, he was so frightened that he shuddered: "Xu, Xu Bureau!"
Everyone turned their heads back, only to see Xu Jubao looking solemn, with his hands behind his back, followed by a young and beautiful female intern, shyly bowing his head and holding a stack of documents, looking very sharp, he must be new .
"What about your detachment?"
"Hey, the Bu Detachment is in the inspection team and is with Director Wang." Cai Lin held Laotan Pickled Cabbage Noodles in both hands, nodded and reported, "More than 300 people went out in the afternoon to check out the taxi companies in the city, Director Wang asked. The traffic control bureau brought in the surveillance video before and after Chen Yuanliang's disappearance, and the two are organizing a visual investigation to conduct an extensive investigation - what are your orders? I'll call you right away?"
Xu Ju nodded and said "uh", but he didn't rush to find Bu Chonghua immediately. He pointed to the bathroom at the end of the corridor, leaned a little closer, and lowered his voice dissatisfied:
"I just went to the toilet and met a man, who looked like a dog, and was quite tall. He was squatting and muttering, 'This broken detachment is not willing to use pure wood pulp for toilet paper. Is it financially good? Don't you? It's not a good business and it's closed down' - who is that person? What are you doing here?"
"Hey, I know," Cai Lin replied quickly: "Yan Xun, the captain of the Jianning Criminal Investigation Detachment, came to share with us the clues of the 502 case. At the same time, he is..."
Bureau Xu was even more dissatisfied: "That can't be so arrogant—"
"...The owner of the Mercedes-Benz downstairs," Cai Lin carefully finished the second half of the sentence: "It's the Mercedes-Benz McLaren that was kicked into half the car's butt by the step team this afternoon."
The surroundings were quiet, and no one dared to look at Xu Ju's face.
"... You can't let customers use low-end toilet paper. It's not good for health and hygiene." Xu Bureau swallowed and said calmly: "Hurry up and let the logistics buy pure wood pulp. In the future, we will use pure wood pulp in the bureau. Wood pulp can't lose to Jianning Municipal Bureau."
Everyone shouted long live, and hurriedly went to the logistics office to pass the order.
Cai Lin raised his chin at the blushing little girl and couldn't help asking, "This is..."
"Oh, this is a new little girl from your criminal investigation detachment." Xu Ju's tone was obviously very loving, and he patted the little girl on the shoulder: "The police picked your detachment to practice for three months, and when Bu Chonghua comes back, you can tell me He said, take good care of it and don't bully others, understand?"
Cai Lin's first reaction was: Xu Tou came down to introduce her personally, this girl is a background party like Xiao Wu, right
But then he dismissed the idea. No little girl with a family background would be willing to come to the Criminal Investigation Detachment for an internship. Even if there were, their legs would have been broken by their parents. It is estimated that Bureau Xu saw the whole family for the first time. The little beauty who was filled with cement is moved by the earth's political work! Is our detachment finally going to have a second police flower besides Sister Meng!
"Yes, yes, I understand, I understand." Cai Lin threw the Laotan Pickled Cabbage Noodles away with a solemn expression, and took the thick stack of documents from the female intern's arms: "I will personally arrange the table. Chairs, eye protection lamps, hand warmers, plush pillows, office slippers, pink mugs, in addition, let the logistics go to Taobao for two pots of succulent and two pots of lucky bamboo. All configurations are based on the highest specifications to ensure that female compatriots will not suffer a little Wronged!"
Xu Ju hesitated: "You go to the detachment..."
"Yes, I understand!" Cai Lin understood: "If he takes the attitude of scolding the little girl in the forensic room last time, I will fight him!"
Xu Ju crossed three fingers, made an appreciative OK gesture, and then told the little girl a few words, and left with satisfaction.
The little female intern was only in her early twenties. She was of a tender age, with almond eyes, willow-leaf eyebrows, and very pretty short hair. Cai Lin had tears in his heart, and his face was still calm, as if he changed from the most annoying cub of the criminal investigation team to a steady and reliable big brother in a second, and asked kindly, "What's your name?"
The little girl pursed her lips and smiled, and said shyly, "My surname is Song."
The surname is Song.
Cai Lin stared at her, but didn't react at all, and suddenly confronted her - bang!
Wu Yu was eating instant noodles while turning around the corner. He almost bumped into the sleepwalking Cai Lin head-on. Fortunately, he dodged in the nick of time, and the instant noodle soup was splashed in the air—
"Hey!" Cai Lin scalded the back of his hand with two drops of soup, and a conditioned reflex let go, and the documents were scattered on the ground.
"Are you OK?"
"What's the matter? It made me make a fool of myself the first time I saw a little girl," Cai Lin said with a sad face, "It's been two years since the last time I saw a living, non-suspect, female creature under the age of 30. It's been a month, can you forgive me?"
Wu Yu put the instant noodle bowl on the window sill, squatted down and picked up the pile of documents on the ground: "You insinuate that Sister Meng doesn't look like she's under 30, so I'm going to report you to Sister Meng."
"?!" Cai Lin said stunned: "My Wu Er's learning is broken!"
With a sigh, Wu Yu gathered up the documents and stamped them neatly. He suddenly caught a glimpse of the contents and his expression became condensed.
- That's part of the signalling record provided by the broadband operator.
"Where did this come from?"
Wu Yu was half-kneeling on the ground, looking down from the female intern's point of view, his delicate eyebrows were raised like swords, his pupils were black and white as clear as cold stars, his shoulders seemed to be a little tight, and he was unusually tall and straight. serious.
The little girl skipped a beat in her heart, and said nervously, "I just passed it over from the operator, and I don't know what it is. Uncle Xu-Xu Bureau asked me to print a part and hand it over to the detachment!"
"What's this," Cai Lin squatted down and turned a few pages: "The network access information records of XX households in XX Lane, Lao Changping District... Isn't this Liu Li's home address?"
"Is this Liu Li's Internet record?" Wu Yu asked.
"Well, yes." Cai Lin turned it over in his hand, and became more and more certain: "Boss Bu said that the murderer took Liu Li's computer, probably because Gao Ling used Liu Li's computer to contact him online. , so let the broadband operator provide records of network access information to see if we can find clues - what? Is there something wrong with this data?"
Wu Yu hummed: "The problem is very big."
Cai Lin couldn't understand the dense traffic data records at all, and was stunned when he heard the words.
"These records contain a large amount of traffic data accessing cloud computing platforms such as Amazon AWS and Microsoft Azure, and both Liu Li and Gao Ling have only junior high school education, so it is impossible and necessary to use such an enterprise-level development platform, especially when the frequency is high. Unusually tall."
Wu Yu looked down at the document, the little female intern unconsciously squatted down and stared at him, clenching her fists tightly, and asked, "Could it be that the murderer stole their computer?!"
"?" Wu Yu glanced at her: "Oh, no."
The little female intern had bright eyes and was extremely nervous.
Wu Yu didn't pay much attention to her, he lowered his head and turned a few pages, "In network investigation, there is a kind of traffic that accesses the cloud computing platform is disguised. User traffic is encapsulated into Firefox's HTTPS payload, and HTTPS is The protocol header for communication between Firefox and cloud computing platforms such as Amazon AWS and Microsoft Azure; after the traffic reaches the cloud computing platform server, the HTTPS content is parsed, and then forwarded again through the transit server. Using this method can allow user traffic It seems that it is just frequently accessing the cloud computing platform, but it is actually a skin that wraps the cloud computing platform and is used to access third-party anonymous networks."
Cai Lin had never heard that gentle, honest and silent Wu Yu speak so much at one time, and his tone was calm and methodical, and he felt as if he had seen aliens land on Earth: "How can this be so?! Hey! , does this mean that Gao Ling bought a VPN?"
"This is no ordinary VPN, and this traffic feature usually only occurs in one situation - the latest built-in traffic obfuscation plug-in in Onion Browser 4.0, called meek, which government firewalls are currently unable to do anything about."
Wu Yu stood up, and both Cai Lin and the little female intern subconsciously followed him and stood up.
"To inform the Bu detachment, we need to ask the broadband operator for the Internet records of Chen Yuanliang, Diao Jianfa, and Li Hongxi." Wu Yu closed the document, frowning slightly, and his tone was condensed: "The murderer took Gao Ling's mobile phone and computer, isn't it? Because I am afraid of exposing the chat records, but I am afraid of exposing the larger dark web behind him."
