Escape From the Library

【Chemical Reaction-06】

The staff dormitory building of the chemical plant has a total of 5 floors. Generally speaking, to avoid the danger of falling from the building, the roof of this kind of dormitory building is closed. Yue Xingwen turned around nervously just now, and saw a man on the roof. Shadows flashed by.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, did you see it?"

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

It was already late at night, and most of the dormitories had turned off the lights and closed the curtains. The two of them flew fast in the air according to Jiang Pingce's trajectory, and no one would notice.

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

Yue Xingwen said: "That's where the guardrail is."

However, 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 already escaped, or is it really that he was dazzled by nervousness?

Yue Xingwen rubbed his eyes, and was about to speak, when suddenly, a sound of footsteps sounded in front of him, Jiang Pingce's arm slammed hard, and immediately brought Yue Xingwen into the air, hid in the corner of the 5th floor wall, and stopped in the air, so as not to be discovered.

The two of them floated in mid-air in the middle of the night without touching the ground. Yue Xingwen believed that Jiang Pingce would not let him fall.The footsteps were getting closer, he immediately held his breath and listened carefully to the movement on the roof.

"What are you asking me to do on the rooftop in the middle of the night?" It was a male's deep and calm voice.

"I, I have nightmares every night recently, and I always feel that something is wrong." The woman's voice trembled slightly, and she sounded very nervous. "On the 20th of last month, Lao Cheng resigned. Didn't his wife suffer from 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, but he never replied to me... On the 3rd of this month, Lao Yi went abroad, and on the 20th, Lao Peng went abroad. 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 they reply to messages, and they 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. After going abroad, they will definitely change their local mobile phone numbers. Otherwise, would they still use the old number to make international calls with you every day? ? It’s normal that you can’t get through.”

"But, but, what about Lao Cheng? Isn't he still in China?" The woman asked puzzled, "I can't get through the phone anyway."

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

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

"That's enough. There's no need to mention the past. I'll go back to sleep first. Don't be idle and be paranoid every day."

The footsteps of the man leaving could be heard in the ear, and the woman walked to the guardrail, took a deep breath, and murmured in a low voice: "Am I really thinking too much? Two of them went abroad and changed their numbers, and one lost their mobile phone. What a coincidence..." She struggled by the guardrail for a moment, then turned and left.

The rooftop was quiet, Yue Xingwen and Jiang Pingce looked at each other, and said in a low voice, "The people who talked on the top of the building 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 group back then, and only Chen Xiumei, Xue Xiaolian, and Lin Yusen are still alive.Xue Xiaolian is a fat aunt who weighs more than 3 catties. The black shadow Yue Xingwen saw just now is very thin, so he judged that it was Chen Xiumei and Lin Yusen who were talking.

Jiang Pingce nodded, and said: "It seems that this Chen Xiumei has ghosts in her heart. She is worried that she will be retaliated against, and she is vigilantly aware that the three old friends who 'resigned' may have been killed. Relatively speaking, Lin Yusen He seemed very calm and didn't believe in revenge, but since he knew Chen Xiumei's concerns, he must have participated in what happened back then."

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

Jiang Pingce said: "I'm afraid only a few of them know this. If we ask directly, we won't be able to find out."

Yue Xingwen thought for a while, and said, "Could Xue Xiaolian also be an insider? I remember she lives in Room 5 on the 501th floor. Let's go and see first. If we can't find any clues tonight, let's wait until dawn and let her know." Qin Lu switched places and slipped in to investigate."

Without further ado, Jiang Pingce took Yue Xingwen to the window of room 5 on the fifth 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, and Xue Xiaolian got up to open the door and talked to someone 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 right away."

There was a sound in the room, and Xue Xiaolian took the hot water bottle to the door and handed it to the other party. After a few words of politeness, Xue Xiaolian closed the door.

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

Soon, Lan Yarong sent a reply from the channel of the research group: "Zhou Qiqi, 35 years old, entered 503 with a water bottle. I pretended to go out to look for things, and I bumped into her."

Yue Xingwen and Jiang Pingce were in the air outside the dormitory building at this time, and could not see the situation in the corridor. He followed up and typed: "Sister, don't go back to the room, just keep an eye on the corridor to see if there is any suspicious person."

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 by the bed and playing with her mobile phone. She lowered her head and couldn't see her expression clearly. She stood up and turned off the Turned off the light, climbed into bed and went to sleep.

After a while, the room of 509 was pushed away, probably because Chen Xiumei, who sneaked up to the rooftop to chat with someone, 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, and someone came back from the next door, and they immediately reported to the research group after hearing the news.

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

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

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

These three key suspects all acted unusually tonight.

It was already 24 o'clock in the evening, and there were only a few "candidates" left in the whole dormitory building. The dormitory lights were still on. To avoid being seen as wrong, Yue Xingwen said: "Everyone, please turn off the lights, the suspects are all gone. Go to bed, take turns sleeping on duty tonight, pay attention to the movement of the suspects, and follow them immediately if they go out in the middle of the night."

Everyone typed one after another: "Received."

Jiang Pingce asked: "Did the students who checked the duty list find any clues?"

Xu Yishen replied: "This factory has 6 production workshops. Zhang Xiaonian and I are in workshop 1, senior brother Liu and Zhuo Feng are in workshop 3, so we only have the shift schedules for workshops 1 and 3. Forms 2, 4, 5, and 6 have not yet been obtained. The four of us have checked carefully just now. The night shift in No. 1 workshop is rotated every 10 days, and the shift of No. 3 workshop is every 8 days. The shift personnel on 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 conjecture of "Black Tuesday" is correct, and the three people resigned on "Tuesday", and the murderer also kills people every Tuesday, then the murderer is likely to be the staff of the chemical plant who is on the night shift on Monday or Tuesday night and forged his resignation After the letter, he started at night to destroy the corpse and wipe out the traces.

There is no such person in No. 1 and No. 3 workshops, and the remaining workshops still need to continue to investigate.

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

Xin Yan said: "Ke Shaobin hacked the computer in the laboratory through the Internet and found all the papers written by Lin Yusen. I have already scanned them quickly. His research direction is sodium cyanide, which can be dissolved with the participation of oxygen. Precious metals such as gold and silver are highly corrosive and produce complex salts of highly toxic substances. Reacting with nitrates and nitrites may cause an explosion. Reacting with acids will also produce highly toxic and easily Combustible hydrogen cyanide gas. However, when it reacts with ferrous sulfate, the resulting sodium ferrocyanide is an important raw material for pharmaceuticals.”

Ke Shaobin concluded: "That is to say, this kind of chemical is very dangerous. Once it is used improperly, it can poison or blow up people in minutes. Lin Yusen's professional research direction is this kind of thing. Both Xin Yan and I think that he uses himself The possibility of killing someone with their expertise is high."

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

The channel of the research group was silent for a few seconds, and Liu Zhaoqing typed: "A top student who graduated from a prestigious school of chemistry more than 20 years ago came to this kind of remote chemical factory. The research is on the application of highly toxic chemicals, which seems to fit the characteristics of a psychopath?"

Yue Xingwen said: "He chatted with Chen Xiumei on the roof of the building just now, and he talked about 'things that happened many years ago', and I and Ping Ce heard their conversation. Chen Xiumei has already begun to suspect that the resignation report of the three is not normal, but Lin Yusen But he said that she was suspicious and interrupted her. If the murderer is Lin Yusen, maybe it was to silence him?"

From Chen Xiumei's words, it can be inferred that they did some bad things together back then, that's why Chen Xiumei went to Lin Yusen to discuss countermeasures with a guilty conscience after her colleagues disappeared one after another.

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

Then, because Lin Yusen had a clue in the hands of these people, he simply killed these people to silence them, and the motive for committing the crime was established.

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