Escape From the Library

【Chemical Reaction-14】

Xiao Wenhui was never seen by other classmates, and Lan Yarong and Lin Manluo, who were in charge of sorting out employee information, didn't pay special attention to him.But Yue Xingwen and Jiang Pingce were deeply impressed by him, after all, he was the team leader in the same office as them.

This slightly fat middle-aged man, with a beer belly, smiled when he spoke, and his attitude was very friendly. It was difficult to associate him with the insane "murderer".

Hearing the two mention Xiao Wenhui's name, Ke Shaobin immediately took out his laptop, opened the chemical plant employee information 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 between chemical factories and other pharmaceutical factories. Do Xingwen and Pingce doubt him? I remember our When the information was sorted out, there was no doubt about his information.”

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

Such a piece of information does not have too many doubts.But is Xiao Wenhui really as simple as it seems on the surface?

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 School of Chemistry, but 40% of the employees recruited by this chemical factory graduated from the School of Chemistry. Based on this alone, how can we determine that he is the murderer?"

Just as Yue Xingwen was about to speak, Jiang Pingce said in a low voice, "Chen Xiumei's death time and process."

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

Xin Yan said: "That's right, Lin Yusen is the director of the laboratory. He is in the office next to mine. He is indeed at his post all day today."

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

Liu Zhaoqing carefully pondered the deduction of the two, rubbed his chin and thought for a moment, then suddenly said: "By the way, there is one more thing. The corpse in the waste water pool has been divided into many parts. If there is too much movement, it is easy to attract the attention of others! It would be much more convenient if the body is dismembered outside the factory and the body parts are 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 information again. The man in the photo looked honest and honest. He really didn't look like a murderer. Holding his glasses, he asked doubtfully, "But what is the motive? Xiao Wenhui's father's surname is Xiao, his mother's surname is Lin, and the deceased Zhou Jianan and him 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 really cannot be explained. He seems to have a happy family, and he is not related to the deceased Zhou Jianan 20 years ago. How could he have such a deep hatred to commit serial murders?

Yue Xingwen carefully sorted out his thoughts, 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 rule out the suspicion. Where is the workshop director, Yu Chenming? Is he at his post this afternoon? "

Zhuo Feng said: "No, when you said you doubted him before, I just kept an eye on him. I haven't seen him in the workshop all day today, so I should have asked for leave."

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

Ke Shaobin analyzed: "If you choose one of these two people, I think Yu Chenming is more likely. His age is only one year older than Zhou Jianan, and with the 'widowed' in his profile, if He is Zhou Jianan's husband, and he came to the factory for revenge, and his motives make sense."

Liu Zhaoqing scratched his head and said, "But I also think that it is quite logical that the murderer is Yu Chenming."

Xu Yishen said with a smile: "Everyone, don't forget that libraries often play their cards against common sense. Before we find clearer evidence, our analysis may also be wrong."

Everyone looked at each other with helpless expressions.

Xu Yishen was right, everything needs evidence to speak for itself.

The current data-based analysis is their subjective judgment and may not be completely correct.

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

What is the "that thing" that Chen Xiumei said?

Yue Xingwen thought of this, and suddenly said: "Our reasoning may have gone into a misunderstanding. Does the 'that incident' mentioned by Chen Xiumei and Lin Yusen in the rooftop conversation really refer to Zhou Jianan's death? If No, the case of Canaan’s death in Zhou became the biggest distraction, and it will completely distract us from our thinking.”

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

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

Ke Shaobin turned his head to look at him, just in time to meet Xin Yan's calm eyes, only to hear him say in a calm voice, "Do you still remember what happened in the library when the sulfuric acid splashed people and disfigured them?"

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 elective course "Orienteering", there was a conflict between student groups competing for score cards. A student from the School of Chemistry directly used his ability to Concentrated sulfuric acid was poured on the students, disfiguring the four girls on the spot.

The sulfuric acid strengthened in the library can quickly melt a ferocious beast into bloody water. The entire faces of the girls who were splashed at that time were instantly corroded to a bloody mess. The skin and muscles on their faces melted into blood, and the scars were deep enough to show the bones!

Such a tragic injury is indeed more terrifying than death.

Even if the scars automatically healed after returning to the library, and their appearances were restored, the girls would definitely never forget this nightmare experience.

In order to prevent such tragedies from happening, the university alliance jointly issued the "Library Student Convention", and also hired senior sisters majoring in psychology to provide psychological counseling to several disfigured girls, and the turmoil gradually passed.

Afterwards, there were no more student fights in the library, and everyone would use their powers carefully so as not to hurt their classmates.However, at the beginning, this incident was like a shadow hanging over everyone's heads. When it was brought up again, it still made people feel chills down their spines.

Seeing Xin Yan's serious expression, Yue Xingwen frowned, and asked, "You mean, the murderer took revenge not because of Zhou Jianan, but because there were others in the chemical plant who were hurt by Chen Xiumei and the others—whether they were hurt or not?" To death, but more cruel than death?"

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

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

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

Xin Yan looked at Yue Xingwen and Jiang Pingce, and said, "The place where we found the corpse was in the waste water pond. The waste water treatment process of the chemical plant definitely doesn't use hydrofluoric acid, which is highly corrosive and dangerous. Then There is only one possibility—there is no hydrofluoric acid in the waste pond itself, but when the murderer threw the corpse into the waste pond, the corpse contained hydrofluoric acid."

He paused, and concluded in a low voice: "In other words, the murderer didn't use sodium cyanide, but hydrofluoric acid."

Xin Yan's words made everyone's eyes widen in surprise.

Although I don't know much about chemistry, after Xin Yan's science popularization these days, everyone also knows that sodium cyanide is a highly toxic substance, and it will kill you in just a few minutes if you take a small amount; and hydrofluoric acid is a highly corrosive substance. The acid, it will not kill people immediately, but will slowly corrode people's skin, flesh and blood like sulfuric acid...

Use sodium cyanide to kill people, and the people are gone in just a few minutes.

But if hydrofluoric acid is used to slowly torture people, then the pain that Chen Xiumei and the others experienced before their death 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 the skin and flesh inch by inch, worse than the "slow execution" among the top ten tortures?

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

Yue Xingwen clenched his fist tightly.

Xin Yan's analysis brightened his mind.

As expected of a reasoning course with 6 credits, there are too many misleading information and distracting items.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 did corrode the bodies of these people with hydrofluoric acid. Did they corrode after killing?Or soak people in the solution to corrode them to death while they are alive, and then throw the corpses into the waste water pool?

Now it seems that the latter is more likely.

The murderer killed people outside the factory. There are countless ways to dispose of the corpse, but he chose the extreme method of "corroding the human body with hydrofluoric acid".The first method of committing the crime chosen by the murderer is usually related to his motive.Perhaps, during these years, innocent people have also been corroded by chemicals, and life would be worse than death?
