Escape the Library

【Chemical Reaction-06】

The staff dormitory building of the chemical plant has a total of 5 floors. Generally speaking, in order to avoid the danger of falling from the building, the roof of this type of dormitory building is closed. Flashing shadows. He rubbed his eyes, but found that the rooftop was empty.

Yue Xingwen decided to tell Jiang Pingce, "I seem to see someone on the roof, have you seen it?"

"No." The direction Jiang Pingce was facing was not the top of the building, but he never doubted Xingwen. Hearing this, he immediately revised the formula and flew up to the top floor directly with Yue Xingwen.

It was late at night, most of the dormitories turned off the lights, and the curtains were drawn. The two flew fast in the air following Jiang Pingce's trajectory, and no one would notice.

Soon, Jiang Pingce gently landed on the roof with Yue Xingwen like a feather, and whispered in his ear with a volume that only the two of them could hear: "Where did you see it?"

Yue Xingwen said: "It's where the guardrail is over there."

However, the assassin, the position of the guardrail was empty, and there was no trace of the shadow at all. Could it be that the other party has escaped, or is it really dazzling under his tension?

Yue Xingwen rubbed his eyes and was about to speak, when suddenly, a footstep sounded in front of him, Jiang Pingce's arm violently pushed Yue Xingwen into the air, hid in the corner of the 5th floor, and stopped in the air, so as not to be discovered.

The two floated in the air in the middle of the night, and their feet did not touch the ground. Yue Xingwen believed that Jiang Pingce would not let him fall. As the footsteps got closer, he immediately held his breath and listened carefully to the movement on the roof.

"What did you ask me to do on the rooftop in the middle of the night?" was a low and calm male voice.

"I-I have nightmares every night recently, and I always feel that something is wrong." The woman's voice trembled slightly, sounding very nervous, "On the 20th of last month, Lao Cheng resigned, didn't his wife have Alzheimer's? I heard that he I resigned and went back to take care of my wife, but after I resigned, I sent him a message and he never got back to me... On the 3rd of this month, Lao Yi went abroad, and on the 20th, Lao Peng went abroad, and they also cut off contact with me after they went abroad. "

"What do you want to say?" The man interrupted her impatiently.

"Yes, could it be, what happened to the three of them?" The woman said tremblingly, "Why don't you answer all the messages, and you can't get through on the phone."

"You think too much." The man said lightly, "Both Peng Yong and Yi Jianqiang have gone to Country M, and they will definitely change their local mobile phone numbers after going abroad, otherwise, will they still use their old numbers to make international calls to you every day? It's normal to be unable to get through."

"But, but, what about Lao Cheng? Isn't he still in the country?" The woman wondered, "The phone can't get through."

"Lao Cheng's phone was lost before, so he must have changed his phone." The man's voice was indifferent, his tone full of displeasure, "You called me to the rooftop in the middle of the night just to say this? You wanted to tell me, These three people were actually killed, someone is hiding in the dark to take revenge on them, and it will be your turn next?"

"I-I'm just worried, what happened back then..."

"Enough, there's no need to talk about the past. I'll go back to sleep first. Don't be idle and be suspicious every day."

The footsteps of the man leaving sounded in her ears, and the woman walked to the guardrail to take a deep breath and whispered, "Did I really think too much? Two people went abroad and changed numbers, and one lost his mobile phone. Will it happen? What a coincidence..." She tangled at the guardrail for a moment, then turned to leave.

The rooftop of the building was quiet, Yue Xingwen and Jiang Pingce looked at each other and said in a low voice, "The people who were talking on the roof just now should be Chen Xiumei and Lin Yusen who are still alive."

There were 7 people who entered the chemical plant in the same batch that year. The only ones who are still alive are Chen Xiumei, Xue Xiaolian, and Lin Yusen. Xue Xiaolian is a fat aunt who weighs more than 150 pounds. The shadow Yue Xingwen saw just now was very thin, so he judged that the conversation was between Chen Xiumei and Lin Yusen.

Jiang Pingce nodded and said: "It seems that this Chen Xiumei has a ghost in his heart, worried that he will be retaliated against, and is alert to realize that the three old friends who 'resigned' may have been killed. Relatively speaking, Lin Yusen He seems very calm and doesn't believe in revenge, but since he knows Chen Xiumei's concerns, he must have also participated in the events of the year."

Yue Xingwen frowned suspiciously: "What happened back then?"

Jiang Pingce said: "I'm afraid only a few of them know this. We can't ask it directly."

Yue Xingwen thought for a while and said, "Will Xue Xiaolian also be an insider? I remember that she lives in Room 501 on the 5th floor. Let's go check it out first. If we can't find any clues tonight, we'll let him know after dawn. Qin Lu slipped in to investigate."

Without saying a word, Jiang Pingce flew Yue Xingwen to the window of Room 501 on the 5th floor.

The lights were still on in the house, and Xue Xiaolian was obviously not asleep. Because the curtains were drawn, they couldn't see what the people in the house were doing, but soon, there was a knock on the door outside, Xue Xiaolian got up to open the door, and talked to people at the door.

The other party asked her, "Sister Xue, can I borrow your kettle, mine is burnt out."

Xue Xiaolian said with a smile, "Of course, just wait a moment, I'll get it for you."

There was a sound in the house, followed by Xue Xiaolian with the kettle to the door and handed it to each other. After the two were polite to each other, Xue Xiaolian closed the door.

Yue Xingwen immediately typed in the research group: "Girls on the 5th floor, go out and see who borrowed the kettle from the 501 dormitory."

Soon, the research group channel sent a reply from Lan Yarong: "Zhou Qiqi, 35 years old, entered 503 with a kettle. I pretended to go out to find something, and I happened to bump into her."

Yue Xingwen and Jiang Pingce were in the air outside the dormitory at this time, and could not see the situation in the corridor. He followed by typing: "Senior sister, don't go back to the room, and stare in the corridor to see if there are any suspicious persons."

Lan Yarong: "No problem!"

Yue Xingwen and Jiang Pingce continued to stay outside the 501 window.

After Xue Xiaolian returned to the room, the room suddenly became extremely quiet, without any sound.

Through the gap in the curtain, Yue Xingwen could see a fat woman with gray hair sitting beside the bed and playing with her mobile phone. She lowered her head and could not see her expression clearly. At 23:50 in the evening, she stood up and turned off the Turn off the light, climb into bed and go to sleep.

After a while, the room 509 was pushed away, probably Chen Xiumei, who had sneaked up to the rooftop to chat with people, came back. Qin Lu typed on the research group channel: "Someone entered 509, it should be Chen Xiumei who lives in 509."

Qin Lu and Qin Miao happened to live in 508. Someone came back from next door. After they heard the news, they immediately reported to the research group.

Yue Xingwen looked at the 509 dormitory, and saw that the lights in the dormitory came on for a while, and then went out again. It seemed that Chen Xiumei had also fallen asleep. He asked in the research group: "How about the third floor, did you hear anything?"

Liu Zhaoqing: "Someone in the 301 dormitory just opened the door and entered the room. If I remember correctly, Lin Yusen lives in this room."

Yue Xingwen and Jiang Pingce looked at each other. Chen Xiumei and Lin Yusen made an appointment to chat on the rooftop of the building in the middle of the night. After chatting, they went back to their rooms. Xue Xiaolian borrowed a kettle in the middle of the night...

These three key suspects all had unusual actions tonight.

It was 24 o'clock in the evening, and only a few of the "examiners" were left with the lights on in the entire dormitory building. In order not to be seen as wrong, Yue Xingwen said: "Everyone, turn off the lights too, the suspects are all gone. After I fell asleep, I took turns sleeping on duty tonight, pay attention to the movements of several suspects, and once they go out in the middle of the night, they will immediately follow."

Everyone typed: "Received."

Jiang Pingce asked, "Have you found any clues for the classmates who checked the duty list?"

Xu Yishen replied: "This factory has 6 production workshops. Zhang Xiaonian and I are in workshop No. 1, and Brother Liu and Zhuo Feng are in workshop No. 3. Therefore, we currently only have the duty platoons of No. 1 and No. 3 workshops. Tables 2, 4, 5, and 6 have not yet been obtained. The four of us have just checked them carefully. The night shift of workshop 1 is every 10 days, and the workshop of No. 3 is every 8 days, and the staff on duty every Monday and Tuesday. They are all different, so no suspects who can commit crimes at a fixed time have been found.”

If Ke Shaobin's "Black Tuesday" conjecture is correct, the three people resigned on "Tuesday", and the murderer also kills every Tuesday, then the murderer is likely to be a staff member of a chemical plant on Monday or Tuesday night on night shift who faked his resignation. After the letter, he started at night and destroyed the corpse.

There are no such people in workshops 1 and 3, and the remaining workshops will continue to be investigated.

Yue Xingwen asked: "Xin Yan and Ke Shaobin, have you found anything on the line of Chalin Yusen?"

Xin Yan said: "Ke Shaobin cracked the computer in the research room through the Internet, and found all the papers written by Lin Yusen. I have quickly scanned it. The research direction he specializes in is sodium cyanide, which can be dissolved with the participation of oxygen. Precious metals such as gold and silver are highly corrosive and form complex salts of highly toxic substances. When reacting with nitrates and nitrites, there is a danger of explosion. When reacting with acids, it will also produce highly toxic and easy flammable hydrogen cyanide gas. But when it reacts with ferrous sulfate, the resulting sodium ferrocyanide is an important raw material for pharmaceuticals.”

Ke Shaobin concluded: "In other words, this chemical is very dangerous. Once used improperly, it can poison and blow up people in minutes. Lin Yusen's professional research direction is this kind of thing. Xin Yan and I both think that he uses his own The possibility of killing someone with their expertise is high.”

Xin Yan added: "There is another discovery, he is 50 years old this year, but he is single and unmarried."

The research group channel was silent for a few seconds, and Liu Zhaoqing typed: "The top students who graduated from the famous chemical colleges more than 20 years ago came to such a remote chemical factory. The research is again on the application of highly toxic chemicals, and you feel it fits the characteristics of a psychopath?"

Yue Xing Wendao: "He was chatting with Chen Xiumei on the rooftop of the building just now, and he talked about 'what happened many years ago'. I heard their conversation with Heping Ce. Chen Xiumei has begun to suspect that the three people's resignation reports are not normal, but Lin Yusen But she said she was suspicious and interrupted her. If the murderer was Lin Yusen, maybe it was to silence her?"

From Chen Xiumei's words, it can be inferred that what bad things did they do together back then, so Chen Xiumei felt guilty and uneasy after her colleagues disappeared one after another, and asked Lin Yusen to discuss countermeasures.

Lin Yusen's attitude was not nervous, and interrupted the other party's words impatiently.

Then, because Lin Yusen had the handle in these people's hands, he simply killed these people to silence them. The motive for the crime was established.

Jiang Pingce said: "Everyone will focus on these people to see if they will take action tonight."
