There is a chemical plant in the southern suburbs, which specializes in processing strong acid and alkaline industrial reagents. Pen~Fun~Ge www.biquge.info Nanyi City will hold an international economic forum meeting this year, and the chemical factories in the southern suburbs have also been ordered to strictly rectify and reform.

Lao Deng pulled his apprentice Xiao Cong and sorted out some scattered blue plastic buckets, Lao Deng said: "Isn't it good to take this bucket back to fill water or something, anyway, there are so many in the factory." ”

Xiao Cong didn't speak, Lao Deng said: "Come on, take a hand, pour out the things in here, I can't move it alone!" ”

Xiao Cong said: "Oh, Master, slow down, don't flash your waist." ”

The two of them tried their best to knock the bucket down, and the bright red liquid slowly flowed out of it, and the floor tiles slowly disappeared everywhere they passed!

Old Deng shuddered and asked, "What is this?" Xiao Cong shook his head and said, "I don't know either." How is it like blood? ”

Lao Deng cautiously walked over, looked at it a few times, and a black charcoal lump came out of it, Lao Deng didn't dare to look at what it was, and said, "I think so, why is it so much like a mummy?" Or call the police. ”

Guan Zheng was sleeping soundly, Li Chongyang ran over to wake him up, and said, "You have a big job this time!" ”

Guan Zheng rubbed his eyes, sat up, and asked, "What kind of work?" ”

"You'll find out when you go."

Guan Zheng stood up, shook his coat, and said, "Xiao Jiu, let's go!" ”

Xu Jiuyan put the things in her painting bag and said, "Okay! ”

Guan Zheng pulled Xu Jiuyan into the car and said, "This case is estimated to be a vicious case, you should be careful." ”

"Got it."

Xu Jiuyan pulled Guan Zheng into the cordon with great interest, but was frightened by the red liquid and vomited.

Li Chongyang asked funny: "What's wrong with you?" Say vomit, vomit, happy? ”

Guan Zheng glanced at him and said, "Get out of here!" ”

Xu Jiuyan pointed at Guan Zheng while spitting, speechless.

Guan Zheng put on his gloves and said, "What are you doing with me?" I didn't do anything, how could I make your belly bigger? ”

Xu Jiuyan ran over in small steps, pretending to spit on Guan Zheng's body. Guan Zheng hid far away, carefully handed the tissue to Xu Jiuyan, and said, "I was wrong, okay?" Don't spit on me. ”

Li Chongyang said while holding the tools: "Sure enough, it's you, entertain truthfully, how many months?" ”

"Fuck you, I'm such a simple person!"

Xu Jiuyan took the water handed by Guan Zheng and rinsed her mouth, and said, "It's all your fault, it's okay to invite me to drink strawberry juice, it's so good, as soon as I see it, I want to ......"

As she spoke, Xu Jiuyan turned around and vomited again.

Guan Zheng smiled and said, "Hear it, I didn't do anything bad?" ”

"That's also your fault, who let you have nothing to do with the girl to drink strawberry juice, look at it, a little police flower was destroyed by you, tsk, hey, everything good things have been put on your stall."

Guan Zheng squatted down and said, "you, isn't the small circle of our forensic office quite good?" I'm a little older, but I'm okay with you! ”

Li Chongyang shook his head and said: "You can pull it down, the small circle has been in the bureau for many years, she was there when I first entered the bureau, and she has not been married until now, which shows the strong deterrent power of forensics, who dare to marry her?" I didn't know that I was dismembered in the middle of the night. Sister Xiaoquan'er will leave it to you! ”

"Who says I'm old?" Liu Huiyuan came in from outside, glared at Li Chongyang, and said, "Dead boy, how many times have I said it, don't call me sister!" ”

"Yes, Sister Xiaoquan'er, uh, no, Dr. Xiaoquan'er!"

Guan Zheng smiled, pushed Xu Jiuyan, and said, "Have you finished throwing up?" After throwing up, come and look at the corpse! ”

Xu Jiuyan wiped the corners of her mouth and said, "This is called a corpse?" It's a puddle of blood! ”

Guan Zheng waved his hand and said, "Blood and water are right, but there will be clues." ”

Xu Jiuyan pinched her nose, leaned over, and asked, "What do you think of this?" ”

Guan Zheng picked up a gold earring on the side with tweezers and said: "The style of this earring belongs to a woman, it can be seen that she was born in the countryside or suburbs, although this earring is gold, but the pattern is not tacky, indicating that the age of the deceased will not exceed 30 years old." Look at this corpse again, although part of it was melted, but the rest of the body was ...... due to charring."

"Uh, that, what does charring mean......"

Guan Zheng looked at Li Chongyang's pure and harmless eyes, and patiently explained: "Carbonization is also known as dry distillation. Thermochemical processing methods for solid fuels. The thermal decomposition of organic compounds into carbon and other products in the isolation of air, and the dehydration of compounds containing carbon, hydrogen and oxygen into charcoal with strong absorbent agents is also called carbonization. ”

Li Chongyang nodded and said, "You continue!" ”

Guan Zheng continued: "The corpse is still intact, although it is difficult to extract intact DNA, but there are small circles, and there is no big problem, huh? In addition, the key points are the identity of the deceased, the motive for the crime, and the source of such a large amount of solvent. ”

Liu Huiyuan blinked her eyes and said, "Oh, no problem!" ”

"The corpses have been charred, but the gold jewelry has not changed, which means that this solution is strong acid or alkaline, but not aqua regia."

Li Chongyang asked suspiciously: "What water?" ”

Xu Jiuyan sighed and explained helplessly: "It is aqua regia, also known as "aqua regia", "aqua regia", "nitro hydrochloric acid", which is a very corrosive liquid with yellow mist, which is a mixture of concentrated hydrochloric acid and concentrated nitric acid in a volume ratio of 3:1.

Aqua regia is generally used in the etching process and some detection and analysis processes, but some metal elements such as tantalum, inorganic salts such as silver chloride, barium sulfate, PTFE, candles and other advanced alkanes are not corroded by aqua regia. Moreover, aqua regia is very perishable and has the smell of chlorine. ”

Guan Zheng looked at Xu Jiuyan with some appreciation, and said, "That's good, I still know Wang Shui!" ”

"It's strange if I don't know, it's obviously junior high school chemistry knowledge, not to mention that I'm a science student!"

Li Chongyang scratched the back of his head in embarrassment and said, "I'm sorry, I just returned it all to the teacher!" ”

Guan Zheng looked at the "charcoal" and said: "No matter what science students and liberal arts students are, just catch the prisoner, how do you say that?" Black cat, white cat, catch the mouse is a good cat! ”

"That's a mouse!"

"Is there a difference between a mouse and a mouse?"

Xu Jiuyan was too lazy to take care of Guan Zheng, so she hid far away alone and went to paint.

Guan Zheng stood up and asked, "Who found the body?" ”

"Two workers, there!"

Guan Zheng beckoned to the two men and said, "Come here, which of you found the body first?" ”

"Me." Old Deng raised his hand tremblingly.

"Tell me more, what's going on?"

Lao Deng looked at Lao Wang and said: "This is my apprentice, this year the factory will be rectified, and a batch of plastic barrels have been eliminated, let's think about it!" ”

"I think I want to take public property for private use!" Guan Zheng said with a smile.

Lao Deng scratched his head and said, "I admit that we are selfish, but I really didn't expect it to be that thing, it's really unlucky!" ”

Guan Zheng looked at Xiao Cong, nodded, and sent the person away.

Guan Zheng looked at Xu Jiuyan and said, "What do you think of these two witnesses?" ”

"It's nothing, it's all normal."

Guan Zheng was silent for a moment and did not speak.

Xu Jiuyan asked, "Do you think something is wrong?" ”

"I don't know, I can't tell what's going on, I always think it's weird."

Guan Zheng walked around a few times and said, "It's almost over, let's almost leave!" ”

"Just leaving?" Xu Jiuyan followed behind Guan Zheng's ass.

Guan Zheng said: "Otherwise? Let's go, please go eat tofu. ”

"Don't disgust me ......"

Guan Zheng stretched out his arm, put it on Xu Jiuyan's neck, and said, "My subordinates not only have to work together, but also eat together, and occasionally sleep in the office!" ”

Xu Jiuyan was still amused by Guan Zheng and said, "It's only been two minutes since you were serious, and your true form was revealed?" ”

"It's all mine, what's the politeness? Let's go, eat tofu and go. ”

"I don't eat ......"
