"What? What rabbit?" Chen Yanfan was confused.
"Let me ask the simplest question, what are the most basic conditions for these cases to occur?" Hua Yitang asked.
Zhang Huai: "Dead person?"
Chen Yanfan: "The murderer?"
Hua Yitang rolled his eyes.
"Yes -" Ling Zhiyan narrowed her eyes, "The murderer and the victim met."
Hua Yitang nodded repeatedly: "My Liulang is still smarter."
Chen Yanfan looked sideways: When did my Liulang become yours? !
"There is an intersection between the murderer and the victim. This is a prerequisite. So if you want to catch the murderer, you only need to find the answers to the following questions." Hua Yitang closed the fan and tapped the end of the fan on the table. " First, where did the murderer and the victim first meet? In this case, where did the murderer kidnap the victim? Second, why did the murderer choose the victim as his target? In other words, these victims What do people have in common? Third, what is the means of transportation used by the murderer? Fourth, where is the murder scene?"
Ling Zhiyan: "The common characteristics of the victims are obvious, they are all young and beautiful women."
Lin Sui'an: "The means of transportation for the kidnapping victim was a carriage, and the body was obviously dumped on a boat. As for the murder scene, the murderer's method of disposing of the body was so complicated that a safe and fixed killing place was needed. The last possibility was to Inside the murderer’s house.”
Zhang Huai: "We already know all this, but it's of no use."
Hua Yitang: "That's not the case. We only need to combine the previous clues with today's clues to deduce the location of the murderer's house."
As soon as this statement came out, everyone was shocked, and Chen Yanfan even exclaimed, "You brat, you think you are a god, how could you possibly calculate this?!"
Lin Sui'an's eyes widened. She had a guess in her mind, but she felt that this guess was too outrageous.
"I am a disciple of the Maoshan sect, and my secret skill is to count with my fingers." Hua Yitang seemed to enjoy everyone's surprise, and even more irritated, "The reason is very simple, a person's habits are fixed, such as when to get up every day, When to eat, when to have tea, when to go out, go to work, go home, and go to bed, these time points are not very different. Similarly, a person's daily route out of the house also follows certain habits, which are basically the same. Around the home, frequently visited shops, markets, shops, work places, etc.”
"For example, Ling Liulang lives in the North District of Dunhoufang. He works at Dali Temple in the imperial city on weekdays. Every morning he sets out from the north gate of Dunhoufang, passes through Lushunfang and Daoguangfang, and enters the imperial city from Xuanrenmen. On weekdays, he goes to buy The East and West also go to the North City, rarely set foot in the South City, and go to the West City even less frequently. Of course, as the director of Dali Temple, Liulang is familiar with the 103th Square of the East Capital, but the most familiar ones are still Dunhou Square, The Imperial City and the Northern City, these three places are the safest and most secure places for him."
Hua Yitang dipped his fan into tea, drew a small circle on the table, and clicked, "The same is true for the murderer. He also has a psychologically relaxed and safe area. This area must be the place he is most familiar with, and often That’s where the murderer’s house is.”
Everyone was confused, but Lin Sui'an gasped repeatedly. She had already heard the clues. Hua Yitang clearly used "criminal geographical profiling", a method that can make inferences based on the interconnections between crime locations. A criminal investigation method to find the most likely place of residence of a criminal - if she remembered correctly, this method requires the huge computing power of a computer. Good guy, does he need to use the human brain to calculate? !
"Wait a minute!" Zhang Huai knocked his head and said, "We don't know who the murderer is at all, and it's impossible to talk about the district you mentioned!"
Chen Yanfan: "You talked a lot of nonsense, and it was completely putting the cart before the horse!"
Hua Yitang put his fan on his forehead, rolled his eyes and cursed in a low voice, "Oh shit, why are you so stupid?" Chen Yanfan slapped the case and stood up, "Who are you calling stupid?!"
"What Hua Yitang means is that the murderer will not - uh..." Lin Sui'an found a word, "will not hunt in his safe zone." After a pause, "For one thing, he is afraid Meeting an acquaintance and exposing his identity, secondly, he was worried that he would be included in the scope of government investigation after the crime. Deep down in his heart, the murderer did not want to destroy this safe zone, so he would not choose this area whether it was kidnapping or dumping the body. "
Hua Yitang showed his shiny white teeth towards Lin Sui'an, "Yes, this is why rabbits don't eat grass beside their nests."
"I understand!" Ling Zhiyan said, "We have to think about it the other way around. Areas where no bodies are found are more suspicious."
"That's Southwest City!" Zhang Huai pointed to the lower left corner of the map, where there was almost no mark by Hua Yitang.
"No, no," Hua Yitang shook his head repeatedly, "The most unlikely place is Southwest City."
Ling Zhiyan: "What's the point of this?"
"For the murderer, the safe zone is inviolable. Similarly, a particularly unfamiliar area will also cause him psychological panic and is not the best choice for a hunting area." Hua Yitang used the same method as Lin Sui'an. Vocabulary, he drew a big circle on the table with a fan, wrapped the small circle inside, and clicked, "This murderer has committed crimes many times, and his methods are sophisticated and cautious. He is very sensitive to unknowns and risks, so, no Will commit crimes in unfamiliar environments."
"For example, the first time he dumped the body was in Luobei City, and it was successful. This formed a special hint in his mind that this area was his feng shui treasure. The second time he dumped the body was still in Luobei City, and it became more and more... Strengthening this hint, so every time he changes his killing method and chooses a place to dump the body, it is always in Luobei City. This is not a coincidence, but his subconscious choice." Hua Yitang smacked his mouth twice, "Every time he finds The corpses are all in different ditches because the murderer will not repeatedly choose each dumping location, which will also increase the risk of exposure."
Chen Yanfan scratched his extremely high hairline and said, "Dear mother, the more I listen, the more confused I become! Can you give me some accurate words, the fourth son of the Hua family?"
"Not too close, not too far, no repetition -" Lin Sui'an dipped his finger in tea and drew a middle circle between the big circle and the small circle, dividing it into three circles, pointing to the core circle, "The murderer The hunting position is not in the safe zone,” referring to the outer circle, “nor the risk zone,” and finally to the middle layer, “but in the comfort zone that is neither far nor near.”
Hua Yitang: "For example, if we want to find a stone that fell into the water, we can calculate it by the ripples formed on the water surface when the stone falls into the water. The comfort zone is the ripples on the water surface, and the murderer's home is the piece of water hidden in the water. The stone below."
Ling Zhiyan, Zhang Huai and Chen Yanfan had three question marks on their foreheads.
"Oh, that's it." A cold voice came from behind, scaring Chen Yanfan to say "Ouch". Fang Ke didn't know when he woke up, looking at the map with his eyes hanging, with a half-smile at the corner of his mouth, " Our current goal is to deduce ripples and then find stones through the ripples. That’s why you asked Jin Ruo to find the places on the paintings."
Zhang Huai: "What painting?"
Ling Zhiyan's eyes widened, then she glanced at Lin Sui'an without saying anything.
Lin Sui'an scratched his forehead, it seemed that he couldn't hide it from Brother Fang.
Hua Yitang shook his fan angrily, "Jin Ruo is too slow. He is really a brat and unreliable."
"Hey, hey, hey, Hua, I heard everything." Jin Ruo hurriedly walked into the office with the little beggar on his back, and placed a roll of paper on the table, "They're all here."
The little beggar raised his hand: "They're all here!"
What Jin Ruo brought was the nine pictures that Hua Yitang had drawn based on Lin Sui'an's golden fingers, and the detailed addresses had been marked at this time.
"It's finally useful." Hua Yitang said in a disgusted tone, but his subordinates were very fast.
Ling Zhiyan stared at Hua Yitang marking the addresses of the paintings on the map, becoming increasingly puzzled, "What are these paintings -"
"Of course I used the secret skills of my Maoshan sect to calculate it with my fingers." Hua Yitang said nonsense, "These are the last places the deceased visited before he was alive."
Zhang Huai was stunned and Chen Yanfan rolled his eyes wildly.
Ling Zhiyan: "..."
Among the nine newly added marking points, Zhou Xinghong’s memory scene is on Quxiang Street in Sishunfang, and the remaining eight points are evenly scattered on different streets and lanes in Fushanfang, Yongtaifang, Yanfufang and Nanshi, forming a The area of Yinnan City is concentrated and the surrounding districts are scattered.
Hua Yitang squinted his eyes and studied it for a long time, then picked up his pen and continued to mark on the map. This time, it was fifteen districts. The eleventh lane in Luonan City: Congshan, Ancong, Gong'an, Daohua, Dunhua, Shangxian, Guangli, Renhe, Hejie, Furen, Liren; the fourth lane in Luonan City: Yuji, Shanglin, Jide, Wenya .
Ling Zhiyan: "This is the address of the fifteen victims' homes?"
Jin Ruo: "I asked my brothers to confirm again. It is true that these fifteen girls do not know each other and have no contact with each other at home. The same goes for Zhong Xue."
Hua Yitang's fan was shaking faster and faster, making his hair on the temples dance wildly. Suddenly, he put down the fan, tied up his sleeves on both sides, and lay on the map. He grabbed a charcoal pen and memorized the nine golden finger points first. Connect the corresponding victim's houses, measure the distance with your fingers, and draw nine circles, large and small, with intersections between the circles. Then, connect the golden finger memory points with the corresponding locations where the body was found. , and drew nine circles of different sizes, and then connected the remaining corpses where they were found. His hand was very steady, and the straight lines were straight, as if he were drawing with a ruler. The circles were very round, as if there was a compass hidden in his hand. ——In addition to the circles and circles drawn before, the right half of the map has almost been covered with various complicated points, lines, and circles. It is simply a mess.
Zhang Huai tilted his head: "What on earth is this?"
No one can answer this question, not even Lin Sui'an.
Now we have entered the deduction and calculation part of "criminal geographical profiling". In her world, this stage is basically completed by computers, computing software and huge databases. She really can't understand it, and can only be confused as everyone else. He stared at Hua Yitang's hand.
Hua Yitang's fingers were dyed dark with charcoal, and he moved quickly among the points, lines, and circles of the map, constantly drawing new lines. The entire desk hall was extremely quiet, and even the little beggar did not dare to take a big breath, so he could only Hearing the rustle of the charcoal pen rubbing against the map, he suddenly paused, threw away the charcoal pen, and spread his palm, "Brush, ink."
No one reacted, Fang Ke clicked his tongue, took out a brush, dipped it in ink and handed it to him. Hua Yitang hung up his wrist and made ink dots the size of rice grains on the map, "Based on the Dongdu water pattern records and corpses in the past five years. Based on the topography and water conditions of the discovery site, combined with the weather conditions in the days before and after the discovery of the bodies, I roughly guessed where the fifteen bodies were dumped. There was a lot of rain this year, so there may be a slight error, but I hope it will not have a big impact."
Ling Zhiyan: "When did you read Water Pattern Record?"
Hua Yitang: "I watched it by the way last night."
Jin Ruo: "Can you remember this?!"
Little beggar: "What are water patterns?"
Zhang Huai's jaw dropped, and Chen Yanfan scratched his hairline wildly, "My treasured maps! All destroyed!"
Hua Yitang raised his elbow an inch, then slowly lowered it one by one, and clicked on the second batch of ink dots, "This is the place where the murderer and the victim met based on the victim's movements during his lifetime, and it is also the place where the murderer hunted. "
Everyone: "!!"
Lin Sui'an: What a guy!
Hua Yitang returned the pen to Fang Ke and said, "Cinnabar."
Fang Ke changed his pen, dipped it in cinnabar again and handed it to Hua Yitang.
Hua Yitang's eyebrows were sharp and he wrote resolutely. He carefully drew four red circles of different sizes on the map, and slowly connected the points. "Based on the hunting location and the dumping location, two versions of the murderer's profile were calculated." One version of the safe zone and the comfort zone applies to the land map, and one version applies to the waterway map. This is roughly the same as the previously inferred result. The murderer used horse-drawn carriages and boats to commit crimes, so two sets of areas were formed——" He smiled "The superposition of two layers of areas can greatly reduce the range of the murderer's residence."
Everyone held their breath in unison.
The crimson wolf hair pen tip slowly moved over the map, crossing over the layers of carbon pen lines, passing through the crimson circles, and finally hovered and lightly clicked on Fuxiao Fang.
"The murderer's home is in this workshop."
The morning air in Dongdu in November is humid, and the smell of dew is so refreshing that it makes me want to sneeze when it gets into my nose. The early morning sunlight was golden, shining through the car window on Hua Yitang's beautiful features, like a thin layer of honey. He was leaning on the brocade-woven cushion, with the end of the fan held against his forehead. His lazy clothes swayed gently with the car, and he seemed to be asleep, with his long hands and feet occupying half of the carriage.
Lin Sui'an, Fang Ke, and Jin Ruo occupied the other half of the carriage with the little beggar in their arms. For the first time, no one complained. The expressions of the four people were indescribable.
Hua Yitang's god-like deduction operation just now caused a great psychological shock to everyone. Chen Yanfan's jaw never closed. Zhang Huai was better, but his eyeballs fell out. Overall, he was the one with the most seniority. The shallow Ling Zhiyan was the calmest, probably because he was often shocked and had gotten used to it. He also proposed a plan for a covert search - Hua Yitang only marked out a small area, and the specific search and investigation work required the cooperation of many parties. , especially the cooperation of the Jingmen is needed (Zhong Xue’s current whereabouts are unknown, so the murderer must not be angered).
At the first quarter of the first lunar month, everyone set off as a team. If nothing unexpected happened, when they arrived at Fuxiaofang, they were just in time to open the gate. Logically speaking, everyone had stayed up all night again and should have caught up on some sleep in the carriage, but everyone, including Fang Ke, was very energetic and no one could fall asleep.
Fang Ke had no expression. He remained expressionless and just stared at Hua Yitang. The little beggar was in Jin Ruo's arms, looking at her with admiration. Jin Ruo's eyes seemed to want to lick Hua Yitang all over. Lin Sui'an looked the calmest on the surface, but in fact, he was already fried inside, with two questions circulating all the time.
Isn’t this guy really a time traveler?
Isn’t this guy really the reincarnation of a computer spirit?
Suddenly, Hua Yitang chuckled, opened his eyes, smoothed his sleeves, changed his position and sat up, his eyes were like water, and his feet were raised high, "Let Hua guess, what are you thinking about now?" ?" He put the fan to his mouth and made an exaggerated expression, "Ah, ah, there are people in the world who are so intelligent and ingenious. It is truly a blessing to be with such a world-famous talent for three lifetimes and meritorious deeds for ten lifetimes!"
Everyone: "..."
Fang Ke: "I really want to cut open his head to see what's inside."
Jin Ruo: "About a few lumps of pig brains."
The little beggar sipped her saliva, "Naohua, it smells so good."
Lin Sui'an: "..."
This guy definitely didn’t travel through time! She never wants to become a fellow villager with such a bastard!
Hua Yitang completely ignored everyone's complaints and shook his fan very nervously. It was damp and cold early in the morning, but he was not afraid of catching a cold. "Come on, little Jin Ruo, let's review some more."
Jin Ruo: "No need!"
Hua Yitang: "I'm afraid your walnut head won't be able to remember."
Jin Ruo rolled his eyes and recited forcefully, "The characteristics of the person we are looking for are as follows: he lives in Fujiafang, is male, is about twenty to forty years old, has a well-off family, owns a boat, a house, a carriage, and has access to opportunities." Precious spices imported from overseas, familiar with the waterways of Dongdu, most likely a businessman, with a decent and kind appearance, and polite manners - Hey, hey, forget the first few, the latter is too ridiculous, how do you know how long this murderer looks like? What, could it be that you calculated it with your fingers?"
"All the victims got into the murderer's carriage unprepared, and were drugged without warning." Lin Sui'an said, "The victims are all young women, how could they easily get into a stranger's carriage?" , so the murderer must have some special way to make them relax their vigilance, maybe he looks kind, maybe he has a special identity, or maybe -"
Lin Sui'an heard a "ding" in his mind, and suddenly remembered a modern typical case, and suddenly broke out in a cold sweat.
The carriage creaked to a stop, and Fu Jiao Fang arrived. :,,
