The police car kept blaring all the way, galloping on the congested street in the evening rush hour, and driving towards the hospital under the curious gazes of countless pedestrians.
"The author of "To see the obvious" is the Australian chemist Arthur Birch, best known for publishing the Birch reduction reaction named after him. "Expression of the Factory Mass Production Method of Amorphous Phosphorus" is an Austrian In the work published in 1848 by the chemist Ent Schlert, Schlert's main achievement was the discovery that white phosphorus is heated to 250 ° C in an inert gas to produce a red allotrope, that is, red phosphorus. Terpenes Otto Wallach, the author of "With Camphor", who won the Nobel Prize in Chemistry in 1910, has another discovery named after himself, called the Liucat Wallach reaction, that is, the reduction of carbonyl compounds with ammonia or amines ammoniated."
Yan Yan held the steering wheel, glanced at the co-pilot, and couldn't help asking, "What does this have to do with kidnapping?"
"The Birch reduction reaction, the red phosphorus reduction method, and the Liucat Wallach reaction have one thing in common." Jiang Ting looked up from the notes left by Chu Ci and said, "—they are the current system There are three main pathways used by drug gangs in the synthesis of methamphetamine."
Yan Yan who was driving: "..."
Han Xiaomei in the back seat: "..."
Both of them had a stunned expression.
"But the implication is too academic, and even his own tutor didn't respond. Are you sure you understand it correctly?" Han Xiaomei couldn't help but ask: "Is there any possibility that he was involved in the production of drugs by himself, he is looking for this How many reference books?"
Jiang Ting's answer was very stable: "There is no such possibility, there are two main reasons: the production of methamphetamine is very simple, and someone like Chu Ci who is extremely talented in chemistry will not need to refer to any materials, he may be in his own kitchen. It can be synthesized from inside, which is one of them.”
"Secondly, I read Chu Ci's notes. He has a slight anxiety disorder, which is obsessive-compulsive disorder. The specific manifestation is that when writing '', he will compulsively stop the strokes on the horizontal line of the notebook page, such as the first letter of writing T. The two strokes are always on top of the horizontal line, forming an extremely precise right angle. If you look at all his notes, you will find that every vertical line is like this, and if the right angle is not straight enough, he will forcibly correct it himself.”
After hearing about it for a while in the back seat, Han Xiaomei raised her head and said stunned: "It's really like this!"
"It's normal." Jiang Ting said, "Chu Ci lives in a very stressful environment. He has to win the top prize every year for papers, experiments, and blogging. His roommate Feng Yuguang has made him restless for a long time. , affective dysregulation is almost tailor-made for this type of person, and a little OCD is not surprising."
He motioned to Han Xiaomei, "Look at the photo album on your phone again."
Han Xiaomei didn't know why, so she opened the photo album. The latest photos were of the discharge port of the storage tank that Jiang stopped taking.
"I checked Chu Ci's experimental notes this week, and found the storage tank that he may have moved, and found that all the discharge openings were placed like vertical lines, exactly against the edge of the floor tiles, at a precise 90-degree angle. Yes, it's his obsessive-compulsive disorder, but look at the storage tanks that were part of it this morning."
Jiang Ting took the phone from Han Xiaomei and gestured to Yan Yan.
Yan Yan turned sideways while driving, his eyes flicked on the phone screen.
The silver galloping roared and changed lanes, like a scalpel, cutting the traffic steadily and ruthlessly.
"These outlets are placed casually," Jiang Ting pointed to the photo album and said, "Just throw it on the ground after use."
"Your hands are beautiful," Yan Yan said casually.
Jiang Ting: "..."
Jiang Ting's expression was blank for a moment, and Han Xiaomei in the back seat was caught off guard and almost exploded into a firework in the sky.
Yan Yan's line of sight returned to the front of the road: "In other words, the person who stole the controlled chemicals is most likely not Chu Ci. He was framed?"
"..." Jiang Ting said, "... Hmm."
The police car driving ahead rushed into the front door of the hospital, clinging to the red light. Yan Yan turned on the light, changed lanes, and did not brake at all when turning a corner. It stabbed like lightning and stopped in front of the emergency department gate.
Yan Yan pushed the door and got out of the car. Five or six criminal policemen had already jumped out of the police car in front of him, which caused constant discussions among the surrounding doctors, nurses, and the family members of patients, and nervous eyes were cast from all directions.
Yan Yan said: "But there is one thing I don't understand."
He hurried to the emergency building, and the policemen followed behind. Jiang Ting's pace was more steady than ordinary people, but this time he couldn't keep up.
"The triangulation performed by the technical investigation shows that Chu Ci's last call was received near the warehouse. With the current criminal investigation technology, the positioning error can be as accurate as 20 meters." Yan Yan asked close to Jiang Ting's ear. : "—You said he was framed, then why did he go to the warehouse in the middle of the night? Is he also being held hostage all the way?"
Jiang Ting frowned slightly, and his face was obviously turned in the other direction. Yan Yan forced him back, forcing him to put his head close to his.
"If he was held hostage, it was impossible not to cause any movement. He walked into the warehouse by himself." Jiang Ting finally gave up after a few tug-of-war-like repetitions, and said helplessly, "If your physicist can learn from the victim's Nian Bowen A trace of Chu Ci's DNA was extracted from the back of his head, which is enough to prove that it was Chu Ci himself who destroyed the monitoring and power system last night."
With a ding, the elevator door slowly closed, and Yan Yan asked, "Why did he go to the warehouse?"
The elevator in the hospital is extremely spacious, and the few criminal policemen entering it are not crowded at all. Everyone looks at the metal wall in unison, peeping at Yan Xun and Jiang Zing from all angles.
Jiang Ting asked in a low voice, "Speaking is speaking, can you not get so close?"
Yan Yan frowned immediately: "Why? What's wrong? Are you a little girl?"
Jiang Ting: "..."
Yan Yan felt that Jiang Ting was very cute at the moment. It was cute when he handed the suspect to the police, and analyzed the various clues of the kidnapping case. Even the appearance of turning his head out at the moment was cute. So Yan Yan encouraged him in a warm tone: "Go ahead, police flower."
Jiang Ting is not short at all. In this place where the height is generally medium, he is 1.80 meters, which is relatively rare.
But as an intellectual athlete who has recovered from a serious illness and is still very weak, his physique can't really be compared with Yan Yan. It's good that the two don't stand so close. Once they are close to each other, it's really a tragic gap between the criminal investigation captain and the long-legged police flower.
Jiang Ting pressed the center of his eyebrows, but Yan Yan was sure that what he wanted to press and pinched at the moment was not between his eyebrows, but his own throat.
"On May 5th, after Chu Ci came to the Municipal Bureau for inquiries, he returned to the chemical company and suddenly gave up half of the experiments he had done, and started to do a lot of tests on the density of solutions. That was the day he knew Feng Yuguang was killed. , Chu Ci's transformation stemmed from this incident."
Yan Yan asked, "What does he want to do?"
The elevator stopped and the metal door slowly opened.
Jiang Ting finally broke free of Yan Yan, adjusted his clothes, and said solemnly, "He wants to verify whether Feng Yuguang's death is related to some secrets of the chemical company."
Jiang Ting strode out of the elevator, Yan Xun walked two steps faster and walked beside him, followed by several policemen, walking through the bustling corridor of the hospital building.
"What are you doing? Can the police arrest people at will, ah? Can the police handcuff people at will?!" A roar came from the emergency room at the end of the corridor: "I am a patient, a victim, you treat me like this I'm going to complain to you!"
A group of people gathered outside the emergency room, and the whispers of "what's going on" and "the police are so rude these days" could be heard clearly from afar.
"Let one give way, let one give way, come, please let the masses let go!"
The criminal police forcibly separated the crowd, and Yan Yan stepped forward and pushed the door; Jiang stopped walking slowly, and walked directly into the emergency room.
I saw a burly, bandaged man handcuffed to a hospital bed, presumably the stabbed security supervisor Diao Yong. Gou Li was guarding the ward with two small trainee police officers. Under the double attack of Diao Yong's injustice and the public's discussion that could not be stopped by the door, everyone's faces were blue and red, and they were very embarrassed.
"Old Yan!"
"Brother Yan!"
Diao Yong looked at Yan Yan and knew that the leader was coming, and his voice suddenly increased: "Who doesn't know that if you enter the Public Security Bureau, you can get out without peeling? Top offense! You officials don't know how many shady secrets there are!"
The trainee policeman said angrily: "You—"
The criminal police shouted to evacuate the people in the corridor and wanted to close the door of the emergency room. Suddenly, Jiang Zing said to Yan Yan, "Let them open the door."
Yan Yan asked in a low voice, "Are you sure you can hold it?"
Jiang stopped and nodded.
Yan Yan gave his subordinates a wink and motioned for two detectives to guard the door.
The crowd of onlookers were all excited, and they stretched their necks to look inside. The discussions of "Did the police arrest people randomly?" and "Have they collected money?"
Diao Yong tugged at the handcuffs, blushed and had a thick neck. He couldn't tell that he was a patient who had been knocked unconscious by a flashlight for several hours: "I'm a witness, I'm innocent! You don't catch the thief, hurry up and retrieve the regulated chemical. Raw material, what's the point of locking me up here?!"
Jiang Ting ordered: "Let him loosen the cuffs."
All the policemen were stunned, and the trainee policeman almost didn't say "what?" out of his mouth.
But he looked left and right, and found that Yan Yan's expression was clearly acquiescence.
"Diao Yong?" Jiang Ting confirmed.
Diao Yong rubbed his hands and replied angrily, "Yes! I said you police..."
"I see that you shouted quite powerfully just now, so it must be no problem to stand up."
"..." Diao Yong vigilantly said, "What do you want to do?"
Jiang Ting turned a blind eye to his attitude, and said lightly: "I read your transcript, when you patrolled the warehouse at 2:30 this morning, you found that the suspect, Chu Ci, was committing theft. I was stabbed with a fruit knife and fell to the ground and was hit in the head, isn't that so?"
Diao Yong said confidently, "Yeah! How could I expect him to be so neat with a knife?"
"What kind of knife is it, how long is it, and does the blade have a curvature?"
"Just... an ordinary fruit knife, it's quite small." Diao Yong gestured, "It's so long, it doesn't have a radian."
Jiang Ting picked up the ballpoint pen left by the doctor on duty at the bedside: "Probably similar to this?"
Diao Yong nodded without hesitation.
"Then if I ask Mr. Diao to repeat the situation at the time of the crime, it should be fine?"
Diao Yong swallowed and said, "Of course, of course there is no problem!"
Jiang Ting, separated by several policemen, waved to Han Xiaomei: "Come here."
"Ah?" Han Xiaomei was slightly stunned, and hesitantly stepped forward to take the pen.
Diao Yong was supported by the police intern, got up from the hospital bed, and stood opposite Han Xiaomei.
Jiang Ting stood beside him with his arms folded and asked, "How far was the suspect from you at that time? Is this the distance?"
The difference between Jiang Ting and the criminal police is that his voice is light, deep and slightly hoarse, which is a sign of poor health. But every word is bitten very clearly, so it sounds like a calm aura that is hard to describe.
Diao Yong scrutinized his eyes and hummed, "Poor... almost."
"Then what were you doing then?"
"I walked over and asked who was there. He heard the voice and immediately stood up and turned off the flashlight. I... I know I'm not a good person, and I was a little scared.
Diao Yong leaned slightly, opened his arms, and pounced on Han Xiaomei.
Jiang Ting asked, "How did the suspect stab you, can you describe to our policewoman?"
Diao Yong's ribs were still bandaged, so Han Xiaomei didn't dare to actually stab him, so she imitated the posture that Diao Yong described, waving the ballpoint pen from top to bottom, the tip of the pen almost stopped above the stabbed part.
"Keep this posture and don't move. What about the criminal camera?" Jiang Ting pointed, "Take a picture."
The technicians brought by Gou Li who were responsible for taking criminal photos and assisting in the identification of injuries hurried forward and took pictures of Diao Yong and Han Xiaomei at the moment.
The unstoppable discussion in the corridor was raging, Gou Li moved a few steps, leaned beside Yan Yan, and asked softly: "Are you sure your friend can hold it, later if the step is too big, it will be a mess. , we might be beaten to death by the angry crowd..."
Yan Yan didn't answer.
As soon as Gou Li raised his head, he was surprised to find that Yan Xun was staring at Jiang Ting with an indescribable gleam in his eyes.
"Old Yan?"
"He's right." Yan Yan said in a low voice, "We didn't even want to understand such a simple truth."
Gou Li: "???"
Diao Yong was injured after all, and he was a little tired from maintaining this position. He asked Jiang Ting impatiently, "Is it okay now, what else do you police have dissatisfied with?"
"No hurry." Jiang Ting said plainly and turned around to ask Gou Li, "—How tall is Chu Ci?"
Just this sentence, Gou Li was enlightened, and he understood everything in an instant!
"It's worse than you—about the same!" Gou Li almost stuttered: "Yes, he's half a head taller than Han Xiaomei!"
Jiang Ting stepped forward to take the pen. Following Han Xiaomei's posture, the tip of the pen went from top to bottom, but it did not stop right in front of the bandage as Han Xiaomei had done just now, but above Diao Yong's chest.
"The wound is in a triangle shape, the ridge of the knife is up, and the blade is down, so the posture of holding the knife must not be a backhand. You said that Chu Ci stood up and stabbed again, then I want to know, Chu Ci, who is half a head taller than the policewoman, How did you achieve such a low position with your forehand stab in a standing position, did you grow 20 centimeters taller out of thin air?"
Diao Yong's face turned pale instantly!
Jiang Ting turned around and threw the pen away, only to hear Diao Yong trembling behind him: "I, I remembered it wrong! He didn't stand up completely, it happened too fast, I didn't think clearly when I made the transcript!"
"Then there are too many things you didn't think about clearly." Jiang Ting interrupted him and said, "You said that Chu Ci turned off the flashlight when he heard the sound, and the scene was very dark; Ordinary fruit knives are about the same length as a ballpoint pen, and the blade has almost no curvature?"
"…!"
Diao Yong was completely softened, trembling and took a half step forward, and was immediately rushed over by a few young and vigorous intern detectives and fell to the ground.
"You must be mistaken, I'm not lying! Wait, I'm injured, I can apply for medical parole!"
Diao Yong was still struggling violently while being held by several policemen, blood seeping through the bandages, looking quite terrifying. But Jiang Ting was unmoved, and wrote lightly: "Take it away, he can't die."
"After we go out later, leave two people here to check the mobile phone, and let the onlookers delete all photos and videos, let alone upload the Internet." Yan Yan whispered to his men, turned to Jiang Ting, and laughed playfully: "Yes Ah, Yuan Fang."
Jiang Ting moved his shoulders and ignored him.
Yan Yan followed behind him and asked, "But the premise of your inferences is that Diao Yong really didn't think about his testimony. If he is a little smarter and has prepared his speeches in advance, how can he find doubts?"
"There is no foolproof perjury in this world, there are only criminal investigators who are not meticulous enough." Jiang Ting walked through the corridor, turning a deaf ear to the countless sights from all directions, and the anti-smog mask made his voice sound calm and a little stuffy: "On Diao Yong's head. The diameter of the blow wound is large. Even if it was caused by a flashlight, it was a traditional household large-caliber aluminum alloy flashlight. Chu Ci went to the warehouse to smuggle chemical raw materials. It was inconvenient to take such a large flashlight. This is a doubt. It can roar so vigorously after being in a coma for a few hours, so the depth of the wound must be fake, and the edge of the wound may be hard ground - of course, after the forensic doctor completes the injury evaluation, it can also be found out, but it will be a little later. Half a day to a day."
They walked into the elevator, and at the end of the corridor in the distance, the detectives took Diao Yong, who was struggling and resentful, out of the emergency room.
"The delay of half a day and a day may delay the life of the kidnapped." Yan Yan murmured.
Jiang Ting hummed.
The elevator slowly closed and descended, and Yan Yan suddenly said, "I heard someone applauding outside just now."
"… "
"It should be for you," Yan Yan smiled at Jiang Stop.
But unexpectedly, Jiang Ting stood beside him with no expression on his face at all, indifferent enough to be described as indifference: "So what?"
"At least the next time someone scolds the police for arresting people and taking the blame..."
"The onlookers who can scold like this will not be moved for more than five seconds." Jiang Ting said lightly, "Go back to the city bureau, I have to stay up all night again tonight."
Yan Yan sighed in a low voice: "Yes."
When the elevator arrived on the first floor, the door slowly opened, and as soon as the wind came in, the two walked out side by side.
