"According to the results of physical and chemical analysis by technical investigation, the victim of the August 28 kidnapping and murder case, Peng Wan, was stained with cornstarch, food coloring, zinc oxide, methyl hydroxybenzoate and other ingredients on part of his hair, shirt collar, and cuffs. That is, prop blood. This plasma was invented in the 1970s for film effects, using cornstarch as a base, zinc oxide as an emulsifier, methyl hydroxybenzoate as a preservative, and then adjusted with blue and yellow pigments The subtle color difference is more realistic and delicate than the fake blood plasma sold in the general market, and it is difficult to see the true and false at a glance even if you observe it closely."
With a clatter of paper, Xiaogui forensic doctor brought the analysis report to Wu Yu and shook it.
In the secret room murder warehouse in the port area, the physicist was squatting on the ground with a flashlight to extract the inspection materials. Wu Yu took the analysis report in his hand and looked at it for a while, then raised his head and looked at Jiang Ting.
"Wu Detachment!" At this time, the physicist got up and strode forward: "The preliminary test results have been obtained, look!"
Wu Yu turned his head.
After Peng Wan's death, the chalk drew a new circle of blood-flow-shaped lines. The position was probably around the neck and throat when the corpse was lying on its side. It was the traces left by the blood of the props, but the pigment had been removed by the murderer. It was cleaned up, leaving only traces of chemical components, for the technical detective to detect the area where the blood of the props was flowing at that time.
"...she can't be..." Xiaogui forensic doctor said in disbelief, "she doesn't want to fake the murder scene, right?"
"If Peng Wan thinks she can create a murder scene just by pretending to be in a coma and a bottle of artificial blood plasma, then her IQ should not exceed 80." Jiang Ting half-knelt beside the outline of the blood stained by the chalk, turning his head to look at Wu Yu : "Your speculation is right, she was indeed deceived by the murderer."
Wu Yu nodded, "The murderer gave her the confidence to fake it."
"Confidence?" Forensic Doctor Xiaogui was full of doubts, "What kind of confidence?"
"Pretend to be dead."
"what?!"
Jiang Ting and Wu Yu didn't speak. Xiaogui forensic doctor seemed to have heard the most absurd joke in his career, and couldn't help looking back and forth at them: "But autopsy, autopsy, body identification..."
"What if the body is lost?"
Xiaogui forensic doctor was stunned, thinking that he was lost
"—'The reason why we were able to rush to the beach ahead of the police, shoot the two kidnappers Ding Sheng and Deng Le, and then rescue you and take you away, is because we are from within the police. When Ding Sheng turned himself in at 110, we Just by the phone. We have been working with Wan Changwen for many years, and will send you and your son to Wan Changwen, but before that, your father needs you to complete a task to prove yourself - play dead and frame yourself A police officer.'"
Wu Yu paused under the surprised eyes of Xiaogui forensic doctor.
"'When we send someone into the back room, it's going to be very chaotic in the dark, you just have to pour this bag of artificial blood around your neck and we'll be an official witness to your death. The police won't immediately find the deceased. Those who touch the corpse will fix the scene at the first time, take photos for proof, and then seal it in a body bag and send it to the forensic car. Once in the car, we will send someone to take you to your father, and then the matter You don't need to worry about it, we will arrange all this within the Jinhai Public Security Bureau.'"
"But, but such a clumsy lie..." The forensic doctor Xiaogui was still very puzzled, "Peng Wan can't believe even a little bit of IQ, how could she really..."
"This is indeed a very clumsy lie, except for two points." Wu Yu said solemnly: "First, Peng Wan was almost torn apart by the kidnappers, and was forced to tell Ding Shenghe the truth about the kidnapping case, and then he was arrested. She was rescued when she knelt on the ground with a knife and waited for the police to turn in. When Ding Sheng called 110, she knew that all her hard work, all her efforts, and all her crazy desire for a better life in the future were gone, waiting for her What happened was the separation of the family and the imprisoned prison. She was probably remorseful enough to die."
"—But," Wu Yu changed his words: "Just when Peng Wan was in extreme despair, waiting for her to be handcuffed and escorted into a police car, someone suddenly came to her rescue, shot the kidnapper cleanly, and claimed to be the Wan Changwen sent her to lead her to the new life she dreamed of—the 50,000,000 grand prize was smashed, and there were very few people who could still maintain a clear judgment. Peng Wan was just an ordinary criminal novice who had nowhere to go. She had no doubts. Immediately choosing to believe is a normal reaction."
Xiaogui forensic doctor recovered from his disbelief and put himself into Peng Wan, who was at the end of his life at the time. All doubts were speechless.
"...Then," he thought for a long time and couldn't help but ask: "You said first, what about second?"
- What's next
Wu Yu opened his mouth, but closed it again, looking at the air in front of him without saying a word, Jiang Ting also focused on the survey report without saying a word.
"Wu Yu? Team Xiao Wu?" The forensic doctor Xiao Gui waved his hand inexplicably.
The physicists were all busy in the distance. There were only the three of them in the small open space around them. The human figures drawn by chalk on the ground were horrific.
Wu Yu finally moved and turned his face slightly. The eye tips under the thick eyelashes seemed to flash with a strange cold light, which was reflected in the pupils of the forensic doctor Xiao Gui.
But his voice was calm and gentle: "—Secondly, they didn't lie to Peng Wan."
"They are indeed the police."
·
Half an hour later, on the way back to the Public Security Bureau.
"—Peng Wan thought it was a test, but the murderer was real." Jiang Ting held the steering wheel with one hand and took out a cigarette case, motioning Wu Yu to smoke it, and he also took out one and bit it between his teeth." So when she entered the secret room, there was a small amount of food in her arms, and by mistake, three-year-old Tao Ze survived, but because of this, Bu Chonghua became suspicious. Bu Chonghua's DNA is left between the teeth and nails, and the planting is just successful."
The location of the Nancheng Branch determines that whenever I go back, there will be traffic jams, the streets are bustling, and there are beeps and whistles everywhere. The cold wind rolled dead leaves across the pedestrian bridge and the changing traffic lights. It was very dark just after two in the afternoon, and the lead-ash cloud was shrouded in the sky above this huge city, as if the first game since the beginning of winter this year was brewing. heavy snow.
"When the rescuers arrived to break the door, it was estimated that she was already dizzy. Even if she didn't faint, she would have thought it was a pre-arranged 'witness' coming, and she would not make a sound and the plan would be revealed." Jiang Ting tilted his head slightly and let Wu Yu Leaning over to fire himself, "But there is a little doubt I can't figure out."
"how?"
"How did the murderer determine that the one who topped the tank must be Bu Chonghua?"
Indeed, if the top tank is Wu Yu, Bu Chonghua will not be dismissed, and Song Ping does not need to avoid suspicion, then the murderer will face an overwhelming sweeping investigation force, which is obviously against the original intention of the design. It took so much effort to come up with the drama of killing in a secret room, even if it could not fully achieve the expected effect, at least it had to achieve the key purpose, otherwise it would be too much for the murderer to lose money.
"You will understand if you change your way of thinking." Wu Yu knocked the cigarette ash out of the window, and said lightly, "Maybe the other party doesn't need to determine who the top tank is. It doesn't matter to him who is the murderer. It's best to drag Chonghua into the water, if it doesn't work, it's the next best thing, getting me out of the police force can also achieve the goal."
Jiang Ting said unexpectedly, "You and Bu Chonghua have a common enemy?"
"Have."
Jiang Ting was startled.
"At first I thought it wasn't, but when I met Bu Chonghua that night, he told me that the shark had already come into contact with Wan Changwen once. The shipping channel of blue gold will go to the Mariana Trench." Wu Wei exhaled a cigarette and looked at Jiang Ting in the curl of cigarettes: "Whoever controls the shipment of blue gold will indirectly control the synthetic drugs in the world. Pricing, which is an asset bigger than gold, is critical to the re-emergence of the Mariana Trench site—and critical to competing sites. And the Mariana Trench's only competitor in Southeast Asia, you know Who is it?"
The dark web was indeed another area for Jiang Ting, but he still reacted immediately: "—The Ancient Tea Horse Road?"
"Yes, this little-known website was run on the Mariana Trench and closed down for several years. It was not until the trench went offline a year ago that the Ancient Tea Horse Road suddenly revived, and within a few months it swelled to become the No. 1 dark web in Southeast Asia. E-commerce." Wu Yu shook his head sarcastically: "I personally guess that the founder of the Ancient Tea Horse Road must also want to cooperate with Wan Changwen very much, but the shark took the lead and kidnapped the trump card of Qinchuan. Wait for the tea horse. When Gu Dao reacted, he could no longer find Wan Changwen from the vast crowd, and only Wan Changwen's daughter and grandson could be found, namely Peng Wan and her three-year-old son Tao Ze."
Beep!
Jiang Ting stepped on the brakes with one foot, Big G stopped on the side of the road in the sound of friction, and several cars beside him whistled and drove away.
"..." The air in the carriage seemed to freeze, and Jiang Ting's face had an ice-like texture in the dark blue light. After a while, he asked in a low voice, "Do you want to tell me that the Ancient Tea Horse Road is from the police?"
Wu Yu said: "I'm not sure, but if we guess like this, we can explain a lot of things. First of all, even if the people inside the police want to trap Bu Chonghua, there are many other methods that can be used, and they don't have to stare at Peng Wan. She is the daughter of the murderer of the Bu family massacre, and has the motive to give in to Bu Chonghua for revenge for the murder, but the cost and risk of rescuing her from Ding Sheng and Deng Le are too high, unless Peng Wan is of value to them It is not just a framing tool. Secondly, Bu Chonghua had already reached a cooperation with Shark at that time, and introduced many blue and gold demolition houses to the Mariana Trench. This situation must be stopped immediately for the Ancient Tea Horse Road. Otherwise, Jinhai It’s hard to imagine the benefits that the adopted son of the city’s top public security bureau can bring to sharks. What if he really helped sharks establish a logistics transfer station in North China? Wouldn’t the monopoly of the Ancient Tea Horse Road in Southeast Asia collapse immediately?”
"But what does that have to do with you?" Jiang Ting frowned and said, "Why does the Ancient Tea Horse Road want to frame you, just to avenge the drug trafficking case in Daxing County ten years ago? It doesn't make sense."
It really doesn't make sense. Drug dealers' revenge against drug police is also divided into different places. This is North China and not the Golden Triangle. Drug dealers forbear for ten years and get revenge at a time. It's better to dream faster.
"I know." Wu Yu leaned on the seat and said hoarsely, his closed eyelids were hazy in the light blue smoke, he saw a haggard blue shadow under his eyes, and after a while he opened his eyes and shook his head: "But I always feel that the tea-horse road is not only exposed in the drug trafficking case ten years ago, maybe I have been in contact with them in the past, or the other party thinks that I already know something, it's just... I just haven't realized it myself. "
—Where does this paradoxical and subtle intuition come from
From which event or scene in the past did it remain in Wu Yu's mind like a clue
Jiang Ting sighed inaudibly, took the cigarette butt that was burning to his fingers from Wu Yu's hand, lowered the car window and threw it into the trash can on the side of the road, and then started the big G.
"People's memory is divided into layers, don't worry if there is no clue for a while, but I tend to believe you." Big G drove through the intersection under the gloomy sky, turned right at the light and entered the gate of Nancheng Branch, Jiang Ting He parked the car under the gray building of the Criminal Investigation Detachment and said, "I'll call Yan Yan later and ask him to keep his distance from the task force as much as possible. The other leaders of the country have contacted, otherwise it would be too dangerous for Bu Chonghua."
Wu Yu lowered his head and said nothing.
Both of them got out of the car. Jinhai was really going to winter, and the north wind got into his neck and it was freezing cold. Wu Yu was wearing a white shirt and black trousers, a black quilted jacket, and black leather gloves on both hands. He looked very sharp and neat; Jiang Ting was wearing a cashmere sweater and coat, with a dark gray scarf hanging around his neck. , walked into the building with his hands in his pockets, turned his head and said to Wu Yu who was behind him: "You have to increase the emphasis, otherwise the lines on your face will be closed, and the whole feeling will be wrong."
"Ordinary people are as detailed as you think." Wu Yu stepped onto the steps in front of the main entrance of the building and said, "I asked the doctor the other day, and it will not affect the sense of smell for the time being. The key now is..."
His footsteps stopped suddenly, and he looked straight ahead.
At that moment, Jiang Ting also felt something, and turned his head slowly, inch by inch.
A group of people is coming out from the door of the building in front, Wang Jiuling and several other directors are following Xu Zuxin, and Xu Zuxin is laughing and patting an old gray-haired expert on the back: "The hard-working old Professor Zhang also made a special trip, this system is optimized to follow Just go to work... Hey, Xiao Wu, you two are back? Let me introduce you!"
Wu Yu's pupils trembled slightly, and the air seemed to freeze, but Xu Zuxin didn't notice:
"Professor Zhang Zhixing is a retired OUHK tutor, a famous network expert of the older generation borrowed by our city bureau. The darknet traffic monitoring paper you studied before was written by someone else! Isn't it amazing?—Professor Zhang, look, this is us Wu Yu, the head of the Criminal Investigation Detachment of the sub-bureau, is younger, you can just call him Xiao Wu..."
Wu Yu subconsciously stepped back half a step, his arms tightened, and Jiang Ting grabbed him.
"Professor Zhang," Jiang Ting gasped slightly.
Zhang Zhixing froze in place, his face blank. He looked at Wu Yu, who was a few steps away, at the unfamiliar and familiar face, and his mind felt dizzy; then he turned his eyes to Jiang Ting, who was also speechless. The scene of the two standing side by side seemed to be It evoked some distant, deja vu clips, and slammed into the head with a bang.
"...You..." He stared straight at Wu Yu, the corners of his wrinkled mouth opened and closed blankly, "You... are..."
"Ah, by the way, Xiaojiang graduated from OUHK!" Xu Zuxin slapped his forehead: "Look at my memory, could it be that Xiaojiang was Zhang Lao's apprentice before?"
Xu Ju looked at them back and forth with interest, followed Zhang Zhixing's dazed gaze, saw Wu Yu's cold and pale face, and finally smelled a strange smell in the air, and was stunned:
"You, you are..."
"Don't you know him, Professor?" Jiang Ting's every word was naturally calm, but the ending was like a bowstring taut to the extreme: "He took an elective course with you for a year, have you forgotten it after so many years?"
"..." Zhang Zhixing closed his eyes and opened them again, as if he was immersed in a nightmare, and finally tried his best to squeeze out a word: "...Solution..."
Wu Yu was trembling all over, unable to speak.
"… Xie Xing," Zhang Zhixing muttered, "you are Xie Xing."
Wu Yu broke free from Jiang Ting's protruding hand and took a half step back nervously, but then Zhang Zhixing was stimulated by this action. He took a step forward from the stunned Xu Ju, then staggered two steps, and the invisible fuse in the void finally burned to the end—
"Come back! Come back!!" Zhang Zhixing jumped up and grabbed Wu Yu who suddenly turned around, shouting hoarsely: "Don't go! Come back and tell me!!"
Xu Zuxin, Wang Jiuling and others were completely stunned.
"Professor, please calm down first." Jiang Ting strode forward and tried to separate the two: "Professor, let's find a place first..."
"How did my son die? What did you tell the investigation team?" Zhang Zhixing turned a deaf ear and grabbed Wu Yu's arm: "What happened the day he committed suicide by jumping off the building, tell me! Tell me!!—"
