Escape the Library

【Chemical Reaction-14】

Xiao Wenhui has never been seen by other classmates, and Lan Yarong and Lin Manluo, who are in charge of sorting out employee information, have not paid special attention to him. But Yue Xingwen and Jiang Pingce were deeply impressed by him. After all, this person was the team leader in the same office as them.

This slightly bloated middle-aged man, with a beer belly on his back, smiles when he speaks, and has a very friendly attitude. It is difficult to associate him with the crazy "murderer".

Hearing the two say Xiao Wenhui's name, Ke Shaobin immediately took out his laptop, opened the chemical plant employee data sheet compiled by Senior Sister Lin, found Xiao Wenhui's copy, and enlarged it for everyone to see.

Lin Manluo glanced at this person and quickly remembered this person: "Xiao Wenhui? He is the team leader of the project department. He is usually required to discuss the projects that the chemical factory connects with other pharmaceutical factories. Does Xing Wenping and Pingce suspect him? I remember us. When the information was compiled at that time, there was no doubt about his information."

Lan Yarong echoed: "Yes, he is 35 years old this year. When Zhou Jianan died in a fire 20 years ago, he was only 15 years old. This age cannot be Zhou Jianan's husband or son. He is an only child, has no siblings, and his surname is Xiao, and neither of his parents has the surname Zhou, so he can't be Zhou Jianan's younger brother."

Lin Manluo said: "More importantly, Xiao Wenhui's information shows that he has both parents, a wife who is a teacher, and a 7-year-old daughter. The family is happy and happy. He has no motive for committing the crime at all, so we ruled it out at the time. he."

There is really not much doubt about such a piece of information. But is Xiao Wenhui really as simple as it seems?

Yue Xingwen asked, "What school did he graduate from?"

Ke Shaobin pointed to the information and said, "It's the Department of Applied Chemistry of the College of Chemistry. However, 40% of the employees recruited by this chemical plant have graduated from the College of Chemistry. Based on this alone, how can we identify him as the murderer?"

Just as Yue Xingwen was about to speak, he heard Jiang Pingce whisper: "Chen Xiumei's death time, and the process of death."

Jiang Pingce just said what he was thinking, and Yue Xingwen turned to look at the other party: "Chen Xiumei resigned this afternoon, and Senior Brother Xu watched Chen Xiumei leave the chemical factory with her luggage, so she must be outside the factory. Killed. And Lin Yusen, whom we suspected before, has not left the chemical factory this afternoon, so it is impossible to kill someone from the air."

Xin Yan said: "That's right, Lin Yusen is the director of the laboratory. In the office next to me, he was indeed on duty all day today."

Jiang Pingce continued Yue Xingwen's words: "But Xiao Wenhui didn't come to work all day today. He called Xingwen and me early in the morning and said that his daughter sprained her foot during dance class, and he wanted to accompany her to the hospital. ."

Liu Zhaoqing pondered the two people's inferences carefully, touched his chin and thought for a moment, then suddenly said: "By the way, there is one more thing, the corpses in the waste water tank were divided into many parts. If there is too much movement, it will easily attract the attention of others! It would be much more convenient if the corpses were dismembered outside the factory and then transported back.”

Yue Xingwen nodded: "So, I suspect that the three people who resigned before were also killed outside the factory."

Ke Shaobin looked at Xiao Wenhui's profile again. The man in the photo looked honest and sincere, and he didn't look like a murderer. He held his glasses and wondered, "But what's the motive? Xiao Wenhui's father's surname is Xiao and his mother's surname is Lin. Zhou Jianan and he are neither siblings nor cousins, what position does he take to avenge Zhou Jianan?"

Everyone fell silent.

If it was Xiao Wenhui who committed the crime, the motive is really inexplicable. He seems to have a happy and happy family, and he has no kinship with the deceased Zhou Jianan 20 years ago. Where does the deep hatred come from to serial murder?

Yue Xingwen thought about it carefully and said, "Chen Xiumei must have been killed outside the factory, so Zhou Qiqi and Lin Yusen, who have been working in the factory this afternoon, can be ruled out. What about Yu Chenming, the workshop director? Are you at work in the afternoon? "

Zhuo Feng said: "No, when you said you doubted him before, I deliberately stared at him. I didn't see him in the workshop all day today. It should be a leave of absence."

Jiang Pingce and Yue Xingwen looked at each other and came to the conclusion: "The murderer is among Yu Chenming and Xiao Wenhui? After all, only those who are not in the factory today can kill Chen Xiumei."

Ke Shaobin analyzed: "If there is a choice between these two people, I think Yu Chenming is more likely. His age is only one year older than Zhou Jianan, plus the 'widowed' in his profile, if He is Zhou Jianan's husband, and he came to the factory to take revenge, so the motives make sense."

Liu Zhaoqing scratched his head and said, "But I think it's too logical to say that the murderer is Yu Chenming."

Xu Yishen said with a smile: "Don't forget, the library often plays cards unreasonably, and our analysis may be wrong until more clear evidence is found."

Everyone looked at each other and looked a little helpless.

Xu Yishen is right, everything needs evidence to speak.

The current analysis based on the data is their subjective judgment, which may not be completely correct.

The only thing that is certain is that the murderer is related to the "thing" that Chen Xiumei said, otherwise, Chen Xiumei would not have nightmares all day after her companion disappeared three people in a row, and asked Lin Yusen to talk on the rooftop late at night, mentioning "revenge." " and the like.

What exactly is "that thing" in Chen Xiumei's mouth?

Thinking of this, Yue Xingwen suddenly said: "Our reasoning may have gone into a misunderstanding. Does the 'that event' mentioned by Chen Xiumei and Lin Yusen in the rooftop conversation really refer to Zhou Jianan's death? If No, the case of Zhou Jianan's death has become the biggest distraction, and it will completely deflect our thinking."

Ke Shaobin rubbed his temples with a headache: "But I searched all the news for the past 25 years. There has only been one murder case in the chemical factory over the years, that is, the 'Death of Zhou Jianan'. If Chen Xiumei has nightmares and runs away in a hurry, then It's not a murder, what else could it be?"

Xin Yan suddenly said: "Some injuries are actually more terrifying than death."

Ke Shaobin looked back at him, just in time to meet Shang Xinyan's calm gaze, only to hear him say in a calm voice, "Do you still remember the incident of disfigurement by throwing acid on people in the library?"

When everyone heard this, their hearts tightened at the same time——

That was when everyone first arrived at the library. In the first school-wide public elective course "Orienteering", there was a conflict between the student groups for the score card. Concentrated sulfuric acid was splashed on the classmates, causing the four girls to be disfigured on the spot.

The enhanced sulfuric acid in the library can quickly melt a beast into **** water. The whole face of the girls who were splashed at that time was instantly corroded and bloody, and the skin and muscles on the face were melted into blood, and the scars were deep in the bones!

Such tragic injuries are indeed more terrifying than death.

Even if the scars are automatically repaired after returning to the library, and their appearance is restored, but this nightmare experience, a few girls will definitely be unforgettable for the rest of their lives.

In order to prevent such a tragedy from happening, the university alliance jointly issued the "Library Student Convention", and also asked a psychology major to conduct psychological counseling on several disfigured girls, and this storm gradually passed.

Afterwards, there were no more students fighting each other in the library, and everyone would use their abilities so as not to hurt their classmates. However, this incident was like a shadow shrouded in the heads of everyone, and when it was mentioned again, it still made people's spines chill.

Looking at Xin Yan's serious expression, Yue Xingwen frowned and asked, "What do you mean, the murderer's revenge is not because of Zhou Jianan, but because of the chemical factory and others who were hurt by Chen Xiumei and the others—does it hurt? Death is more cruel than death?"

"Well." Xin Yan said calmly: "Actually, we can think about the murderer's modus operandi. At first, we all suspected that the murderer used a highly toxic chemical such as sodium cyanide, because cyanide only needs a few grams. It can poison an adult, and the effect is very fast. In addition, the factory warehouse also stores this dangerous material. If the murderer can find a way to get it, he can serially kill in the chemical factory without knowing it."

Yue Xingwen followed Xin Yan's train of thought: "But now, we found out that the murderer did not kill in the chemical plant, but did it after Chen Xiumei and the others left the chemical plant?"

"That's right, since the murder is outside the chemical plant, the murderer doesn't necessarily use sodium cyanide to poison people to death quickly, he can also slowly torture people to death."

Xin Yan looked at Yue Xingwen and Jiang Pingce, and said, "The place where we found the body is in the waste water tank. The chemical plant's waste water treatment process will definitely not use hydrofluoric acid, a highly corrosive dangerous substance. Then There is only one possibility - there is no hydrofluoric acid in the waste pond itself, but when the murderer put the body into the waste pond, the body has hydrofluoric acid on it."

He paused and concluded in a low voice, "That is to say, the murderer did not use sodium cyanide, but hydrofluoric acid."

Xin Yan's words made everyone at the scene widen their eyes in surprise.

Although he has little knowledge about chemistry, after Xin Yan's popular science in the past few days, everyone also knows that sodium cyanide is a highly toxic substance, and if a trace amount is taken, it will die in just a few minutes; and hydrofluoric acid is a highly corrosive It will not kill people immediately, but will slowly corrode people's skin, flesh and blood like sulfuric acid...

Kill people with sodium cyanide, and in just a few minutes, people are gone.

But if people are slowly tormented with hydrofluoric acid, then the pain that Chen Xiumei and the others have experienced before they die is unimaginable! What would it feel like to splash something that can corrode even jade on the skin? ! Isn't the pain of using chemicals to corrode skin and flesh inch by inch, even more tragic than the "Long Chi execution" in the top ten tortures?

It would be terrifying if the subject of chemistry was used by someone with a heart!

Yue Xingwen clenched his fist tightly.

Xin Yan's analysis made his mind suddenly clear.

As expected of a 6-credit reasoning course, there are too many misleading information and distractions. If the murderer had nothing to do with Zhou Jianan, the direction of their previous investigation was all wrong!

Thinking about it carefully, the murderer really used hydrofluoric acid to corrode the bodies of these people. Is it corroded after the murder? Or soaking people in a solution to corrode them while they're still alive, and then throwing their bodies into a waste pool?

Now it seems that the latter is more likely.

The murderer kills people outside the factory. There are countless ways to deal with corpses, but he chooses the extreme method of "hydrofluoric acid corrodes the human body". The first way the murderer chooses to commit a crime is usually related to his motives. Perhaps, during these years, innocent people have also been corroded by chemicals, and life is better than death?
