Escape the Library

【Chemical Reaction-20】

Others did not dare to touch the dangerous chemicals, but Xin Yan quickly went into the basement, found a pair of plastic gloves in the drawer and put them on, opened one of the jars and checked them, and nodded to everyone, confirming that the liquid was hydrogen. Fluoric acid.

Liu Zhaoqing glanced at the basement and said, "Xiao Wenhui's chemical laboratory has been remodeled quite professionally. It reminds me of the biological and chemical weapons processing factory in horror movies..."

Xu Yishen said, "How did he get the raw materials needed to make so much hydrofluoric acid?"

Xin Yan walked around the laboratory and found some unused materials in the cabinet, which looked like crystal materials. He picked it up with gloves and observed it carefully for a while, and soon came to the conclusion: "These should be It is fluorite, which is often referred to as 'soft crystal', and its main chemical component is calcium fluoride, which can produce hydrofluoric acid."

Ke Shaobin asked curiously, "Is this kind of thing easy to buy?"

Xin Yan said: "It's very easy to buy. It's more than twenty yuan per catty. If you buy it in bulk, you can buy a ton for a few thousand yuan."

Yue Xingwen walked over to Xin Yan, looked at the stone in his hand and said, "So, Xiao Wenhui doesn't need to get raw materials from the chemical factory? Can he buy it directly from the Internet?"

Xin Yan nodded: "Well, as long as you know chemistry and know how to prepare it, you don't have to take the materials from the factory. I think the police will definitely gain something by checking his purchase records."

Ke Shaobin opened his laptop and pulled out the case data of Qin Ru and Xiao Nianru's mother and daughter that he had just copied, and said, "From the case, Xiao Wenhui's wife and daughter were accidentally hospitalized five years ago and were discharged after two months of treatment. In January, when the school was about to start, he told the school teacher that his wife and daughter drowned, and Xiao Nianru didn't go to school after that."

He paused, looked at Liu Zhaoqing and asked, "Senior brother, I don't understand what the doctor wrote. In your opinion, after the mother and daughter are discharged from the hospital, do they need to return to the hospital for a long-term follow-up?"

Liu Zhaoqing looked at the case carefully and said, "From the test sheet, all the indicators recorded in the discharge record and the inspection data have returned to normal, which proves that the infection has been completely controlled. Their injuries are only limited to the face, and the infection has been controlled. As long as you pay attention to your daily medication, the condition should not suddenly deteriorate."

Ke Shaobin adjusted his glasses and looked at everyone with some doubts: "So, after Qin Ru and Xiao Nianru were discharged from the hospital, they couldn't go to work or school because their appearances were completely damaged. Xiao Wenhui said that they drowned and completely disappeared from the public eye. Out of the protection of their self-esteem? Xiao Wenhui wants to bring the two of them here and take care of them in secret?"

Yue Xingwen said: "That's right. His intention was good, and he wanted to hide his wife and daughter to take care of them in secret, so as not to be pointed at them when they showed up. Unfortunately, they died later. This is why Xiao Wenhui suddenly took revenge. ?"

Jiang Pingce said calmly: "Brother Liu just said that when the two were discharged from the hospital, the infection was already under control, and the condition should not suddenly deteriorate. Disfigurement does not develop and spread like cancer, so how did they die? "

Liu Zhaoqing didn't quite understand either. He scratched his head and said, "Could it be that they got sick later? However, the mother and daughter were both sick at the same time, and they were serious enough to die. It doesn't make sense."

Just when everyone was wondering, Xu Yishen suddenly said: "I thought of one thing, when I went to Xiao Wenhui's residence to investigate, I happened to bump into him watching a horror movie! The female ghost in the movie was also disfigured, with a rotten face, especially Disgusting, but Xiao Wenhui has a calm face..."

Ke Shaobin remembered the picture described by Senior Brother Xu, and his goosebumps trembled.

Jiang Pingce said coldly: "He may have killed his wife and daughter."

Everyone: "..."

This speculation sent a chill down everyone's back.

Yue Xingwen looked at Jiang Pingce, frowned and asked, "What do you mean, Xiao Wenhui wanted to take care of his wife and daughter at first, but after a long time, facing those two faces that were corroded into rotten flesh every day, would he not Be patient, and even feel disgusted. Over time, they are already dead anyway, and if they are killed, no one will notice?"

Jiang Pingce nodded: "The so-called 'no filial son before the bed for a long time', if he really loved his wife and daughter, he should not have let them die socially. If the person I like is injured, I will take care of him and encourage him , accompany him out of the haze, instead of hiding him in a dark corner and living like a mouse."

I always felt that Jiang Pingce said these words to himself. Yue Xingwen's ears were hot, he coughed lightly, quickly looked away, and pretended to be calm: "So, Xiao Wenhui doesn't actually love his wife and daughter, he loves his own face more."

Ke Shaobin carefully sifted Pingce's words, and finally straightened his thoughts: "Yes! Wife and children are disfigured. If you really love them, you should find ways to treat them instead of hiding them! He is afraid that others will talk behind their backs and say that his wife is his wife. You and my daughter are ugly as ghosts, so I forcibly hid them!"

Liu Zhaoqing couldn't help but scolded: "This beast! On the surface, he looks like a dog, but his mind has long since been twisted! He took care of his wife and children for five years, and gradually he couldn't bear their ruined faces, so he killed them ruthlessly. And then took revenge on the person who disfigured them in the first place?"

Jiang Pingce said: "The logic makes sense. Otherwise, how could his wife and child die all of a sudden when he was discharged from the hospital five years ago?"

Xin Yan frowned and said, "According to the police investigation data, there is no record of Qin Ru and Xiao Nianru being cremated in the local crematorium, so the corpses of the mother and daughter..."

Ke Shaobin froze: "Could it be in this basement!"

Everyone just felt numb.

Xu Yishen acted quickly, and immediately used "mitosis" to send four replicas to search. Most of the splits are efficient. Within five minutes, he searched the laboratory and found a freezer in the corner.

Xu Yishen looked back at everyone: "Be mentally prepared."

Yue Xingwen said: "Let's go, anyway, with the experience of scooping up corpses in the waste water pool, I'm not afraid of the disgusting corpses."

Although he said so, the moment Ke Xu Yishen opened the freezer and saw the picture in the freezer, everyone was still like a basin of cold water was poured over their heads in the cold winter and the twelfth lunar month, and the soles of their feet were chilled.

——In the freezer, there are a lot of human bones frozen.

There is no flesh and blood, only bones, and they are also sorted.

Ke Shaobin retched twice and quickly turned his head away. Liu Zhaoqing stepped forward with a calm expression and said, "From the perspective of the pelvis, it is an adult woman and a little girl under the age of 10."

Xin Yan's face was pale, and his eyes were freezing: "So, it was his wife and daughter that he first corroded with hydrofluoric acid? This pervert, just did a chemical experiment with his wife and daughter?"

Ke Shaobin said in a trembling voice: "It's terrible! This kind of homicidal maniac who has received high education and mastered scientific knowledge is really more terrible than the perverted demon in horror movies!"

Jiang Pingce said coldly: "Xiao Wenhui took his wife and daughter to this secret place to take care of him at first, but after a long time, he became impatient and disliked the mother and daughter more and more. It would be fine if it was directly corroded to death, without so much trouble, so he began to transform the laboratory, and purchased materials to make highly corrosive potions to solve these two 'troubles'."

Yue Xingwen said: "Usually, serial killers have a sense of superiority after successfully killing the first victim, 'they can dominate other people's lives at will'. They solved their wives and daughters and mastered the skills of killing. , he launched a revenge plan."

Jiang Pingce said: "Because he has worked in a chemical factory for many years, he knows the habits of those people well, I guess he must use some excuse to deceive those people to kill them outside the factory, and then forge their resignation letters to make them resign. Fake."

Peng Yong, the reason for his resignation was to go abroad to take care of the newborn twins and granddaughters; Yi Jianqiang, the reason for his resignation was to emigrate with his children abroad; Cheng De, to resign and go home to take care of his partner...

The three employees who resigned before, if you look closely, they all have one thing in common - it is difficult for colleagues to find them after they resign.

It is exactly the same as Xiao Wenhui's usual "socialized death"!

He let his wife and daughter die in the past and disappeared from the eyes of colleagues and classmates. Now, he can also let these people disappear from the eyes of the public quietly.

Chen Xiumei felt that there was a problem and voluntarily resigned to seek refuge. As a result, after she left the chemical plant, she was stopped halfway by Xiao Wenhui, who had been waiting outside for a long time. After Xiao Wenhui threw Chen Xiumei's body into the waste water pool, he simply set fire to destroy the body and burned the last participant, Lin Yusen.

Thinking of the first day he came to the chemical plant, Director Xiao greeted himself with a smile, pretending to be a father who loves his daughter when he called, and his tone was full of worry about his daughter's "broken leg"... …

Yue Xingwen only felt the chills on his back stand upright.

Some people are no longer worthy of the title "people".

***

On the third day of the exam, the C183 research group successfully solved the case.

Since they used Jiang Pingce's coordinate system to fly all over the city overnight, they found out all the context of the case, and met the library's condition of "solving the case before the police", so this course could be passed smoothly.

After dawn, the police will definitely find the secret laboratory, and Xiao Wenhui will definitely be brought to justice. It's a pity that his wife, daughter, and those dozens of chemical plants who died innocently in his maddened revenge. Staff.

After returning to the base, everyone learned about Xingwen's investigation results, and their moods were very complicated.

Chemistry is a very important subject. The reactions and reorganization of various chemical substances are as complex and interesting as magic. People who really love chemistry have been using their professional knowledge to study and solve various problems encountered by human beings in the fields of medical treatment, industry, and manufacturing.

Instead of using the acquired expertise to harm people.

Xin Yan is very clear that Xiao Wenhui is a rare example of a demon of high knowledge. In reality, there are countless researchers who have devoted themselves to chemical experiments, and they deserve people's admiration and respect.

This is his favorite subject. He will also continue on the road of chemistry and go on firmly.
