Although Chen Yifei concluded that Xue Dong was in trouble, as a police officer, she could not say these words to the family of the deceased. She had to look for various clues to eliminate the possibility of murder.

Chen Yifei still retrieved all the surveillance videos of the Special Alloy Materials Factory to see if there were any abnormal people and abnormal things before and after Xue Dong's death.

Before Xue Dong died, something strange happened in the lounge in the second workshop. Lu Xin was electrocuted but did not die, and he also obtained the benefit of storing electricity. If someone saw the strange scene before and after Lu Xin was electrocuted, he might have been scared.

However, the lounge in the second workshop was not air conditioned and hot as a stove. No one came to join in the fun. There was no surveillance facilities installed in the lounge, so no one knew about Lu Xin being electrocuted.

Chen Yifei watched all the surveillance videos and found no abnormalities. When the hammer fell, there was no one near the windowsill. There was no possibility that someone would push the hammer down and smash Xue Dong to death.

She took a look at the position where the top hammer was located and found that the top hammer was placed more than ten centimeters away from the windowsill. Even if the wind blows strongly, it would not be possible to blow down such a heavy thing, let alone there was no wind at that time.

Moreover, workers in the machining workshop on the second floor reported that the top hammer was not placed on the windowsill, but one meter close to it. I don’t know when it suddenly moved to that place.

The more Chen Yifei heard it, the more she felt cunning. She originally thought that Xue Dong was unlucky, but now she was a little suspicious that it was a murderous element.

But she looked carefully at the monitoring equipment next to the machining workshop. There was indeed no one near the windowsill at that time. If there were no one, how did the top hammer go down? As described in some movies, the criminals used a special mechanism.

She squatted near the windowsill and searched carefully, and could not even find a decent clue.

Chen Yifei was a little discouraged and had to ask Xue Dong's colleagues one by one, asking if Xue Dong had any strange actions before his death and if he had contacted anyone.

An old colleague in the mechanics class reported that Xue Dong looked very uneasy a few hours before his death, and kept hiding in the lounge, restless, as if he had something to worry about.

Chen Yifei began to associate the recording of Xue Dong's drunkenness and scolding the leader with Xue Dong's death. She studied the recording, studied who Xue Dong scolded the most and who hated Xue Dong the most. As a result, Du Haibo, the deputy director of the equipment factory, and Xue Dong scolded him the most and scolded him in person.

However, after investigation, Chen Yifei found that when Xue Dong died, Du Haibo was attending the equipment work meeting in the Alloy Department and had no chance to commit crimes.

In the end, she had to handle the case on site in the lounge of the machine repair class, asking Xue Dong's colleagues, relatives, and friends one by one, asking them what they knew about Xue Dong, asking them if they knew who Xue Dong hated the most, who they were most afraid of, and who they had the deepest conflict with.

There was no such thing as Xue Dong's drunkenness and scolding the leader, and letting the people in the mechanics class recall it. They would definitely say that Lu Xin and Xue Dong had the deepest conflict. After all, those old colleagues were all cunning and knew that Xue Dong had a brain problem and did not know him as much as he did, so they usually gave in to him. Only Lu Xin was young and energetic and often fought with Xue Dong. The relationship between the two was once very tense.

But within two or three days after moving last Sunday, Xue Dong seemed to have softened his attitude towards Lu Xin, and the relationship between the two was not that nervous. In addition, these old colleagues could not have imagined that a weak college student, Lu Xin, could have anything to do with Xue Dong's death. In addition, Xue Dong was drunk and insulted those leaders, these lower-level employees all had some views on the leaders and naturally let the conspiracy theories cause. It was said that Xue Dong had a disagreement with many leaders, and everyone listed the names of many leaders.

Chen Yifei's last count found that Xue Dong offended too many leaders during his more than ten years of working in Sanjiang Group. Fortunately, he is a relative of the Li family. Otherwise, with this guy who is so perverse that he is comparable to Du Wenze in Xiangjiang, it would be a miracle to be able to stay in Sanjiang Group.

Looking at the long list, Chen Yifei was in a splitting headache and investigated them all, and Sanjiang Group was no longer in chaos.

The last person to accept Chen Yifei's inquiry was Liu Jianhui, the head of the Equipment Department. Liu Jianhui did not directly state that the leaders had conflicts with Xue Dong, but directly mentioned Lu Xin's name, saying that Lu Xin had many conflicts with Xue Dong before, and almost fought several times. He also added jealousy to his old colleagues, such as rudeness, irregularity, and rudeness. Finally, he said directly: "I suspect Lu Xin is the murderer!"

On Sunday afternoon, the group of people in Turtle Cang extorted Lu Xin. Lu Xin brought Chen Yifei to arrest the people in Turtle Cang. Many people in Sanjiang have seen this scene, but Liu Jianhui was lying in the hospital at that time and did not see it. If he had seen it, he would definitely not and dare not say bad things about Lu Xin in front of Shen Yifei.

After recent contact, Chen Yifei's impression of Lu Xin has changed greatly. He thinks that he is upright, helpful, speaks nicely, and is handsome. Except for being younger, he has no major shortcomings in other aspects. A person who has a good impression of him in his heart, but Liu Jianhui said that this is how Chen Yifei is naturally unhappy.

She glanced at Liu Jianhui's cheeks wrapped in gauze and her eyelids covered with tiny flesh. She slowly felt disgust in her heart. After hearing Liu Jianhui's words, she probably understood that maybe it was not that Lu Xin and Xue Dong had a strong holiday, but that Liu Jianhui and Lu Xin had a personal grudge.

Chen Yifei waved his hand quietly and signaled Liu Jianhui to go out: "Call Lu Xin over, I'll ask him carefully!"

Liu Jianhui thought his words had worked, and was very happy, smiling so hard that his face was like a chrysanthemum blooming.

He hurried out and walked to Lu Xin who was standing outside the door, laughed and said, "Officer Chen asked you to go in and ask!"

There was a pride in Liu Jianhui's eyes. Lu Xin, a bastard college student, was finally driven away by me. I can sit in my seat for a few years and make money for another few years.

Lu Xin saw Liu Jianhui's obscene smile and knew that he hadn't said anything good to Chen Yifei just now. He laughed in his heart, bastard, if you know my relationship with Shen Yifei, you may not be able to laugh.

Chen Yifei saw Lu Xin coming in and wanted to pretend to be serious with a stern face, but found that it was difficult for him to be serious when facing his sunny smile. She smiled at the other two policemen in the room and said, "I know this guy, he can't be the murderer. You go out and learn about the situation with others. I'll just chat with this guy!"

When Lu Xin saw Chen Yifei handling the case in this way, he laughed in his heart. This woman is emotional and is really not suitable to be a criminal policeman.
