How could Chen Xiumei resign suddenly? When she saw her on the rooftop last night, she also panicked and told Lin Yusen about the first three old colleagues who had resigned, suspecting that something had happened to these three. Now that she had also submitted her resignation letter, wasn’t she afraid that something would happen to her?

Yue Xingwen looked at Jiang Pingce and said, “Do you think she voluntarily resigned to avoid the limelight, or was she threatened?”

Jiang Pingce frowned. “Last night, she panicked on the rooftop, plus she has been having nightmares lately. It’s likely that she sensed that someone had taken revenge on them, so she wanted to resign and go home to save her life. If she is threatened, she should immediately turn to Lin Yusen to discuss a countermeasure in the first place. I’m more inclined that she submitted her resignation on her own initiative.”

Yue Xingwen had the same thought. Jiang Pingce agreed with him, making him more confident in his reasoning. He sent a message on the chat channel: “Who is responsible for the personnel department? Go and see what is going on with Chen Xiumei.”

Qin Miao said: “Roger, I’m following up.”

Yue Xingwen asked: “Is Lin Yusen coming to work?”

Almost as soon as Yue Xingwen’s message popped up, the door of the laboratory was pushed open, and a man wearing silver-rimmed glasses and a white coat walked in quickly. His expression was cold and serious, walking in front of Xin Yan and Ke Shaobin, throwing a piece of material to Xin Yan and said, “You two hurry up and finish the experiment. Give me the data today.”

Xin Yan took the material and said in a low voice, “Got it Director Lin.”

Ke Shaobin stayed by the side and did not dare to come out, until Lin Yusen turned around and left the laboratory. Ke Shaobin adjusted his glasses and whispered, “What experiment did he let you do?”

Xin Yan lowered his head and quickly flipped through the materials and said, “Preparation of hydrofluoric acid, as well as the measurement of the concentration of hydrofluoric acid dissolving metals… The experiment isn’t hard to do. It’s probably the grading item for students in the Faculty of Chemistry in the course exam.”

Ke Shaobin nodded. “Oh, is it the same as the side quest released by NPCs in online games? If we can’t complete this experiment, it won’t affect the clearance. If it’s done, there will be extra points, right?”

Xin Yan looked back at him and said, “It can be interpreted that way.”

Ke Shaobin, who was recognized, smiled brightly, rolled up his sleeves and asked, “Can I help?”

Xin Yan averted his eyes from his face and said lightly, “Don’t make trouble, just stay on the side.” Sensing that his tone was too cold and hard, Xin Yan paused for a moment, and then added in a low voice, “The preparation of hydrofluoric acid requires the use of concentrated sulfuric acid as a material, and the experiment has a certain danger. Non-professionals should stay away from it, so as not to encounter chemicals that should not be touched.”

Ke Shaobin immediately went to sit down three meters away from the experimental table, and said with a smile, “Understood! Not messing with you is the greatest help to you. Am I far enough here? If it’s not enough, I can go further.”

Xin Yan: “…..”

This guy really entertained himself no matter what.

Xin Yan raised his eyebrows and said, “You go ahead and hack into the factory’s intranet to look up information, and I will handle the experiment.”

Ke Shaobin made an OK gesture and took out his laptop.

Xin Yan put on gloves and began to experiment step by step, while Ke Shaobin buried his head and quickly tapped on the laptop. The two of them were busy with their own works and looked serious.

On the chat channel, Ke Shaobin quickly sent a message to reply to Yue Xingwen: “Lin Yusen has assigned us an experiment, and his expression is quite normal. It doesn’t seem like he knows about Chen Xiumei’s resignation. His office was next door, and after entering the office, he never went out again.”

Yue Xingwen asked: “Over at the warehouse, whoever doesn’t have a task now, you can go and make a contact.”

Xu Yishen took the initiative to say: “I’ll go. Xiao Nian and I will be working on the night shift tonight, and we’re off during the day, so it’s a good time to slip over to the warehouse and have a chat with the two warehouse managers.”

Jiang Pingce reminded them: “You guys be careful, don’t be too deliberate and cause people to be suspicious.”

Xu Yishen said: “I know.”

After a while, Qin Miao sent the investigation of Chen Xiumei’s resignation in the chat channel: “Chen Xiumei went to the General Manager Zhang’s office. I passed by and heard their conversation. General Manager Zhang advised her to think and consider it, but Chen Xiumei’s attitude was very resolute. She said that her health was getting worse and worse, she just wanted to go home and rest for a year or two, and then find a leisurely job.”

Yue Xingwen said: “How is her mood?”

Qin Miao said: “If I listened to her voice, it seemed normal, there was no sign of panic or nervousness. On the contrary, she was quite calm, as if the decision was made after considering it for a long time.”

Yue Xingwen and Jiang Pingce looked at each other, and a trace of doubt rose in their hearts at the same time.

Qin Miao immediately said: “After Chen Xiumei came out, I made an excuse to enter Mr. Zhang’s office and saw her resignation letter. This letter is different from the previous ones, I secretly took a photo. I’ll send it to everyone to see.”

Qin Miao’s photo appeared in the group built by Yue Xingwen. She put her mobile phone behind her back to take a sneak peak, the angle was a little awkward. Everyone had to twist their necks 90 degrees to see it clearly. Yue Xingwen tilted his head to look at it carefully: “All handwritten, the handwriting is very neat, and there is no scribbling. It seems that it’s not written down in a hurry.”

Jiang Pingce said: “The previous three resignation letters were all printed, and only the signature part had the handwriting of the three people. Chen Xiumei’s resignation letters are all handwritten, so it proves that our speculation just now is correct—— She realized the danger and wanted to resign voluntarily and leave this place out of guilt.”

Yue Xingwen nodded: “Therefore, although she is nervous in her heart, she will try to disguise herself as calm as possible on the surface, write a neatly written resignation letter, and calmly explain the reason in front of the boss. In doing so, she didn’t want to arouse the suspicion of her colleagues. My guess is that she has already packed her bags and will leave this Chemical Factory within the day.”

Sure enough, Qin Lu replied: “She came to the finance department to settle this month’s salary. Her expression was indeed quite calm and she greeted us with a smile. Someone asked her why she resigned, she said it’s because she’s not well and wants to go home, resting for a year or two.”

Qin Lu paused and said worriedly: “Today happens to be the end of the month, the process on the financial side is approved very quickly, and the salary will be directly sent to her bank card next month. It seems that Aunt Chen Xiumei will leave the factory before noon. Will she also be like the previous three, who disappeared after resigning?”

Qin Miao said coldly: “If that’s the case, the murderer is likely to do something to her.”

Ke Shaobin actively suggested: “Do we need to protect her? Close protection, waiting for the murderer to appear?”

Zhuo Feng said helplessly: “The library will definitely not let us directly bump into the murderer committing the crime, that will be the same as directly having the answer on the paper sent to you by the exam! I guess we can’t leave the Chemical Factory during the exam, so once Chen Xiumei walks out of the Chemical Factory, we can’t interfere with her ending.”

Liu Zhaoqing also followed closely and complained: “That’s right. The original Faculty of Medicine, in the beginning, the murderer committed the crime at night, so the library pulled all of us examinees to another space to fight monsters at night, to avoid the examinees from staying up all night and waiting for the murderer to take action. The Chemical Factory must have restrictions on keeping us out of certain places too.” He said: “Xiao Xu, quickly send your mitosis to walk around and see if you can get out.”

Xu Yishen smiled and said: “Roger, my five brothers will act immediately.”

During the day, the employees of the factory were working in the office and workshop. Xu Yishen and Zhang Xiaonian because they were on the night shift and rested during the day, the two of them wandered around the factory, but did not attract too much attention.

Xu Yishen ran to the entrance of the Chemical Factory quickly with mitosis, and a prompt sounded in his ears: “Warning, please do not leave the examination room without authorization, or else you will be punished by failing the course.”

Xu Yishen stopped and typed in the chat channel: “Sure enough, I was warned. The Chemical Factory is the exam room, and the examinees are not allowed to leave.”

As soon as he finished typing this line, he suddenly heard the sound of footsteps. Xu Yishen turned his head, and saw Chen Xiumei carrying a suitcase and walking quickly towards the door.

Xu Yishen hurriedly said: “It’s over, Chen Xiumei is so fast, do I have to stop her?!”

Yue Xingwen immediately decided: “Stop her!”

Xu Yishen immediately split off a replica and teleported behind Chen Xiumei, gently patting her shoulder and smiling, “Hello Aunt Chen.”

Chen Xiumei turned back alertly, and suddenly met the smiling gaze of a handsome man.

Chen Xiumei: “??”
