In the conference room, Sun Mingrui first said: "Yesterday we took all the new bricks at No. 49 Qilin Lane back for testing, and finally extracted a small amount of diester alkaloids from three of the bricks. After experimental analysis, we finally determined For acetobenzoylacronine..."

Pang Guanglong: "Brother! Speak human words!"

"...commonly known as Fuzijing, also known as aconitine."

Lin Huan asked suspiciously, "What is that?"

"A kind of element exists in Aconitum and Aconitum." Su Xing explained, "Many people are poisoned by drinking the medicinal wine made from Aconitum, which is actually poisoned by aconitine. Aconitine is highly toxic, and 0.2 mg of aconitine The amount of poisoning has been reached, and more than 2 mg is the lethal dose, but when I took Zhang Ge’s blood for the second time for testing, I found that the residual aconitine content in his blood reached 10.7 mg/ml.”

Qiao Chen asked, "Then it wasn't detected the first time?"

Su Xing: "The first time I tried my best, I did a routine poison inspection but there was no result. At that time, I thought of unconventional poisons, but because the scope of unconventional poisons is too large, I didn't have a clue for a while, so I didn't dare to test rashly. Afterwards, I went home and read some books, and chatted with the experts from the provincial appraisal center. I sent the blood samples there yesterday morning, and the results I got this morning together with my experimental results confirmed that it was aconitine poisoning.”

Qiao Chen: "This amount of aconitine is not found in other parts of the body? Even the contents of the stomach are not detected?"

Su Xing nodded: "Yes. Because the dead body has been dead for nearly two months, and one of the characteristics of aconitine is that its structural components will be destroyed due to corruption. If aconitine extracted from fresh corpses is not handled properly, it will lead to The test was negative, and there was an additional factor in Zhang Ge’s corpse, so it was indeed a missed test the first time.”

"What additional factor?" Pang Guanglong asked.

"Brick wall." Su Xing said, "This wall is made of traditional red bricks and lime mortar. There is also residual lime mortar on the surface of the corpse. The pH value of lime mortar is greater than 7, and aconitine is in alkaline substances It is easier to be decomposed in the medium, and high temperature is also the reason that promotes the decomposition of aconitine. It is summer now. From June to August, there is a lot of rain in the city and high temperature. Several factors together lead to the residual aconitine on the corpse. It was quickly decomposed and destroyed, and only a small amount of aconitine was extracted from the three bricks at the foot of the corpse where there was more corpse water."

"I'll go!" Pang Guanglong exclaimed, "This is too small! If we find out a little later, wouldn't we be able to find nothing?"

Su Xing: "According to the results of my experiment last night, if we wait half a month later, the aconitine in our heart will be decomposed, and then we will really be unable to find anything."

"Su! You are amazing!" Pang Guanglong gave Su Xing a thumbs up.

Su Xing smiled and shook his head: "I actually didn't do anything, the bricks were checked by Brother Rui and colleagues from the Laboratory Department, the heart blood test was also the result from the Provincial Identification Center, and even the lime slurry was reminded by Team Yan , I dare not be greedy for credit."

"You are worth the spirit of staying in the laboratory for one night." Pang Guanglong sincerely praised, "You guys are really good at technology!"

"Okay." Yan Lan knocked on the table, "Zhang Ge's autopsy report can be made first, and your task for the next period of time, Su Xing, is to find the death tool for the unknown corpse."

Su Xing knew that this matter was still in the confidential stage, so he replied following Yan Lan's words: "I know, Captain Yan, don't worry."

Yan Lan continued to ask: "Sun, did you find anything about the altar I gave you yesterday?"

Sun Mingrui: "No strange fingerprints were extracted. However, I found an opening at the back of the altar, and got a knuckle print of a middle finger inside. It is speculated that someone once hid something in the dark compartment behind the altar and was picking it up. The knuckles of the middle finger were printed inside. This thing is not like a fingerprint. We don’t have a database for comparison. It can only be used as supporting evidence after you catch the suspect. Of course, I have ruled out Zhang Ge, Li Yue and that waste product. Recycler, confirm that this knuckle print does not belong to the three of them."

"It can be regarded as a clue." Yan Lan said, "You and the laboratory staff have worked hard. If you feel tired, you can take turns to make up for last weekend. Mr. Wang is not here, so you can discuss it yourself."

"no problem!"

Yan Lan waved his hand and said, "The task of the criminal department is completed, we have a small meeting left, you two can go to rest."

Sun Mingrui pulled Su Xing out of the conference room. He was afraid that Su Xing would not adapt to this situation, so he explained to him: "It's okay, we have indeed completed the task, and there is no need to listen to the criminal investigation with them. I guess it was given by the superiors." What other tasks did they arrange? You will get used to it in the future, they often do this in criminal investigation and anti-narcotics, and some deployments have a high level of secrecy, and second-line civilians like us are not qualified to know."

"I know, Brother Rui, I didn't think much about it." Su Xing responded with a smile.However, the real thought in my heart is: I guess only you don't know.

In the conference room, everyone knew that there was something wrong when they saw Yan Lan dismissing the people from the criminal department, so they subconsciously raised their spirits and waited for Yan Lan to speak.

Yan Lan turned on the projector, projected a few comparison photos on it, and said, "Not much to say, this meeting room won't exist if the next thing happens."

Everyone nodded in understanding.

"This photo is an indentation on the back of an unknown corpse in an urban village. After comparison and screening, we confirmed that it was caused by two types of stretchers, HS-AL102 or HS-AL103 produced by Haisheng Medical Instrument Company. The department purchased these two models for the public security system in this city. Qiao Chen and I have ruled out all the retail channels on the market in the past two days, which means that the stretcher that caused the indentation on the deceased’s back is likely to be from our own people. In addition ..."

Yan Lan called up the second set of photos: "The left side is the skull fracture of the unknown corpse, and the right side is the experiment done last night. The experimental tool is the jack in the toolbox of our police car. It has been confirmed that the deadly tool is the jack."

"The next photo is a screenshot of the video taken by the driving recorder when the municipal garbage truck was working at the Denglai Road garbage dump at 8:1 a.m. on August 2."

Yan Lan zoomed in on the photo, and at the edge of the white light projected by the intersection of the headlights of the two cars, it was vaguely visible that the coming car was a white Iveco.Yan Lan said: "This car is very vigilant. After finding a garbage truck, it immediately turned on its high beams and avoided the shooting range of the garbage truck's driving recorder. This is the only shot of it. White Iveco is not uncommon. The blue logo on the car body may be the logo of a certain company. Now the focus is to check the white Iveco with the blue logo. At the same time, we need to check which companies have the same brand of jack in the tool box as our police car. I have never Assume the worst, but you all have to be prepared.”

———Some police cars in Pinglu City are also white Iveco.

Seeing that everyone understood what he meant, Yan Lan continued to ask, "Lin, have you made any progress?"

Lin Huan shook his head: "There is no progress for the food delivery company. Except for Meng Jianguang's food delivery company, the background of other companies has confirmed that there is no trace of modification. At the same time, the food delivery staff of each company who often deliver food in the West District also said that they have not seen it." Have that private meal."

"Team Yan, there may be clues from Qingyuan." Pang Guanglong held his mobile phone and said, "A tenant before No. 7 Courtyard has been unable to be contacted. Qingyuan feels that something is wrong and wants me to go with him to take a look."

Yan Lan turned his pen to think for a moment and said: "Fatty, you take Qingyuan to confirm, and leave the task of finding the body parts to Lin and Bai. About this Iveco, Qiao Chen and I will keep an eye on it. The anti-narcotics will answer whatever they ask. I don't know, let Yu Sen come to me directly if there is something to do. You two have a good relationship in private, don't talk nonsense if you shouldn't."

"understand!"

There was a burst of noisy footsteps in the corridor, and then Deputy Director Liu pushed the door open and entered: "What are you doing in a daze?! Hurry up and change clothes! The leaders of the department will be here soon!"

"I go……!"

"I've forgotten it all!"

"Leader, is it time to run now?!"

"I haven't worn a uniform in 800 years!"

"I'll give you 5 minutes!" Deputy Director Liu left the conference room without saying this.

Five minutes later, two well-built middle-aged men in white police uniform shirts stepped out of the police car, each with a silver olive branch and three four-pointed star flowers on their shoulder straps.

"My God! The first prisoner! Is higher than the police rank of the Wu Department..."

"Nonsense! That's the head of the ministry!"

"Just like Wu Ting, they are at the main hall level, but they are in the Ministry."

"Both of these two look younger than Ting Wu, so I guess they can be promoted to Deputy Chief Superintendent, right?"

"Why do you ride in a police car? Is it uncomfortable for four laps?"

"Who is that leader at the back? Why are there two bureau chiefs here?"

"The one in front is the director of Bureau 21, and the one behind should be the director of Bureau Five."

"It's normal for the director of the anti-narcotics bureau to come, and to give Yu Zhi a title and listen to their work report. These five bureaus..."

"Team Yan and the others caught the serial murderer in five days, isn't it worthy of praise?"

"Cough!" Director Jiang Weiyang's slap in the face shut up the little policemen who were whispering behind them.

Whether it is the 21st round or the fifth round, it has nothing to do with the Criminal Division. Su Xing has always been able to hide from this kind of scene. Now that Wang Jun is away, no one will drag him to meet the leaders. He was originally He planned to lock the door of the dissecting room, pretending to be busy, and just hide in there.Unexpectedly, Sun Mingrui, a guy with the opposite sex and no humanity, insisted on dragging Su Xing to join in the fun, because "I want to see Lin Huan in police uniform".Lin Huan has a slender and tall figure because of learning dance since she was a child. If it wasn't for the incident ten years ago, she should be a pillar of a certain dance troupe by now.Originally, there were fewer female police officers in the police station, and even fewer were in good shape. The good-looking people in the front line were basically on the same level as pandas.Every time an "image project" was needed, the leader would approach Lin Huan, but was rejected every time.Almost everyone in the Municipal Bureau knows Lin Huan's famous saying: "My old lady lost more than 1000 people in PK and was admitted to criminal investigation. I didn't come here to be a vase for you."

Therefore, in the so-called "propaganda", there has never been Lin Huan wearing police uniforms, and because of the needs of criminal investigation work, except for special occasions, they are basically in casual clothes, and the number of times they have worn police uniforms can be counted on one hand.It's rare to see Lin Huan wearing a police uniform these days, so Sun Mingrui will naturally not let this opportunity pass.

Su Xing stood in the back corner, and at a glance, he could only see Yan Lan, who had a height advantage. Yan Lan, who was over 1.9 meters tall in leather shoes, was thrown into the crowd and couldn't hide even if he tried to hide. .In fact, Su Xing had never seen Yan Lan wearing a police uniform. At this time, no one noticed him in the corner, so he let go of his thoughts and stared straight at Yan Lan.

Su Xing always thought that Yan Lan was the flower of Gaoling, who was good-looking, had a good family background, and worked hard.How can I say something?The rich second generation is not terrible, the terrible thing is that the rich second generation works harder than you.Yan Lan is such a frightening rich second generation and official second generation.Until now, Su Xing still thinks that he can't climb up to Yan Lan. With Yan Lan's background, what kind of person does he have to be worthy of him?Su Xing thought to himself for a while, except for his own face, there was nothing worth Yan Lan's liking.So what can they do in the end?Is it greedy for a moment of tenderness or just continue to fool around like this?In fact, Su Xing was more inclined to the latter, anyway, no one has spoken so clearly now, so it is enough to bypass this topic and just be a "friend" in Yan Lan's mouth.After a long time, the feeling has faded, and it's okay to turn this page. When the time comes, he will marry a well-matched man, and he will continue to deal with the corpse, and maybe he can calmly joke "I liked you back then".

Su Xing was staring at Yan Lan's back in a daze, but he didn't expect Yan Lan to turn around suddenly. He couldn't dodge in time, and met Yan Lan's eyes directly.Yan Lan raised his right hand, tapped his eyes with his index and middle fingers, and then turned his finger to Su Xing's eyes. Su Xing lowered his head in embarrassment, and pulled Sun Mingrui back into the small gray building.

By the time the leaders of the ministry left, it was already close to off-duty time.

"Su, I'm off work!" Sun Mingrui poked his head into the forensic room, "Are you still leaving?"

"I'll stay a little longer and want to check some more information."

"Don't be too late. You stayed up all night yesterday. Go home today and have a good rest. If you get tired and get down on the ground, Mr. Wang will kill me!"

"Don't worry, Brother Rui, I know it well."

"gone!"

As soon as Sun Mingrui left, the door of the forensic room was pushed open again, and Su Xing teased, "Did the footprints fall?"

"Who?"

Su Xing turned his head and saw Yan Lan standing at the door, and quickly stood up: "Team Yan. I thought it was Brother Rui who came back."

"Still off work?" Yan Lan asked.

Su Xing quickly packed up his things and said, "Aren't you working overtime?"

"I have something to do at night, so I have to go home and change clothes, so I'll take you home." Yan Lan glanced at his watch, "Is 5 minutes enough?"

"Enough." Su Xing quickened his movements.

"You can drive by yourself tomorrow." Yan Lan said to Su Xing who was sitting in the passenger seat, "This case is nothing to do with you now. You have to wait for me every day. It's inconvenient for both of us."

"Okay." Su Xing nodded, "Actually..."

"Actually what?"

Actually, I shouldn't stay at your house like this anymore, Su Xing thought.

"It's nothing, so you won't be at home for dinner tonight, are you?" Su Xing considered his words and tone, but he still couldn't find a way to make this sentence less ambiguous.

Yan Lan didn't seem to be aware of Su Xing's embarrassment, he replied as usual: "Yes, if you are too lazy to cook, you can order takeaway, or if you want to eat now, I will have someone prepare it and deliver it to your home. "

"Don't bother Captain Yan, I can do it myself."

Yan Lan put her hands on the steering wheel and asked casually, "What are you looking at me doing this afternoon?"

"I didn't look at you."

"I don't think Wu Ting and those two directors are worthy of your gaze, unless..."

"Unless what?"

Yan Lan smiled and said, "Unless you like Uncle."

"It's not!" Su Xing turned his head away.

"Come on, let's talk, do you often peek at me like this?"

"Team Yan, excessive narcissism is a disease. I can introduce some counselors and psychiatrists to you. Self-awareness disorders need treatment."

"I think your behavior of peeking behind others needs more treatment."

"I told you I didn't look at you!"

"Okay." Yan Lan patted Su Xing's hand with a smile, "Stop talking, little hedgehog is shy."

"Not a hedgehog!"

"Okay." Yan Lan put her hands back on the steering wheel, "I know what you wanted to say just now, although it is true that no one has followed you these two days, but you still can't take it lightly. Besides, your car hasn't been repaired yet, and you're alone again It’s not convenient or safe to go home now. It won’t be too late for you to move home after this case is over and I have time to find out.”

"Thank you Team Yan."

"You have said thank you countless times, don't say it again."

"..." Su Xing remembered the dream he had at noon again, and he subconsciously shook his head.

Yan Lan was a little puzzled: "Aren't you happy to ask you not to be polite?"

Su Xing: "No, I'm distracted."

"Are you tired? Your hands are so cold, don't cook when you go home, I'll have someone prepare it and bring it to you."

"It's really not necessary." Su Xing turned his head to look at Yan Lan, "I really can't live in your house if you continue like this."

"Okay." Yan Lan raised her eyebrows and drove away quietly.
