When I returned to the bureau and put the two photos in front of the butcher, the butcher stood up and looked at the photos dumbfounded, and couldn't say a word for a long time, and when he reacted, I saw beads of sweat coming out of his forehead, and he fell into the chair with his chest clutched, his breathing became rapid and heavy, but his face was even heavier.

Nian Weimin's ancestral home has also been investigated clearly, the three of them have known each other since childhood, they are all from the same place, I can understand the butcher's mood, he has been a criminal investigator for so many years, what it means to put such evidence in front of his eyes, he understands better than anyone else.

"Zhou Baiman mentioned in her memories that she accidentally saw Mu Hanzhi arguing with a man in one place, she couldn't see the man's face clearly, but she smelled formalin on the man's body." I took a deep breath and said to the butcher. "It can be seen that the person has access to medical drugs."

"Xiao Bowen is a forensic doctor, and he spends the most time in contact with formalin every day, maybe he doesn't know that a person who has never been in contact with it can easily smell it." Yun Duruo stepped forward and took a step to add.

"Jiang Bureau, Mu Hanzhi's case has now come to light, she and Mu Xiaoxuan did not jump off the building at all, but were killed in the room, the body was moved to the roof, Mu Xiaoxuan was thrown down from the roof, and finally threw Mu Hanzhi's body treated with sulfuric acid down." I looked at the butcher and asked eagerly. "The reason why you concluded that Mu Hanzhi committed suicide back then was because there was no one when you got to the roof."

The butcher still clutched his chest and nodded with a struggling expression.

"Then think about it, when did Xiao Bowen appear?" I looked at him very earnestly and asked.

The butcher's eyes were flustered and thought for a moment, his face became more and more pale, and his expression became painful, I suddenly realized that Aunt Tan said that the butcher's blood pressure was too high recently, and it must have been a sudden stimulation that made his blood pressure go up again, I hurriedly helped the butcher to sit on the chair, took out the medicine and sent it to his mouth, Yun Duruo brought water and the butcher swallowed it, and it took a long time to recover.

"I immediately asked someone to close the scene, and Xiao Bowen appeared on the roof of the building twenty minutes later." The butcher gasped and replied.

"Did you tell him to come?" I asked.

"I thought it was another colleague......" the butcher stopped in the middle of speaking, closed his eyes and sighed weakly.

Yun Duruo and I glanced at each other, and we also knew what the butcher realized, this is inertial thinking, the butcher received the alarm that Mu Hanzhi jumped off the building, and he would not notify the forensic doctor until the murder occurred.

But Xiao Bowen appeared at the first time, when the butcher's attention was all on the falling case, Xiao Bowen's appearance he would habitually think that it was notified by other colleagues, and other colleagues present would think that it was the butcher's notice, and they didn't pay attention to why Xiao Bowen appeared.

"Where did you first see Xiao Bowen?" Yun Duruo suddenly thought of something.

"On the roof...... butcher paused again, his mouth now wide open.

I sighed heavily, this is the most critical point that was ignored by the butcher twenty years ago, and it also led to the butcher's fatal misjudgment of the whole case, after the crime the butcher went to the roof, according to his recollection, he arranged for the police to cordon off the scene at the first time, in order to protect the scene and wait for investigation.

No one can come up, even if Xiao Bowen appears at the scene as a forensic doctor, he should only do a preliminary identification of Mu Hanzhi and Mu Xiaoxuan's bodies downstairs, and he will definitely not appear on the roof.

The bigger loophole is that it is still inertial thinking, and the colleagues who blocked the scene will not consider Xiao Bowen who is extra out of thin air from the roof, and the butcher's first reaction when he sees Xiao Bowen will only be that he has just come up from downstairs.

Maybe it is possible to think about it if you change to someone else's butcher, but it is Xiao Bowen, who he regards as a confidant, and in the butcher's consciousness, Xiao Bowen should appear at the scene of the murder, and he will not even doubt and question Xiao Bowen.

"If I'm not mistaken, the person who called the police to you back then was also Xiao Bowen, and he deliberately asked you to deal with Mu Hanzhi's case." I said in a deep voice.

The butcher did not speak, his eyes were closed, his head resting on the back of his chair, his expression was painful, but he could see that the pain was not a physical pathology, but a psychological pain, calculated and used by his best friend.

Xiao Bowen took advantage of the butcher's familiarity with him, and all the unreasonableness became natural at that time, I know how uncomfortable the butcher's heart is at this moment, there are reasons why his negligence caused Mu Hanzhi to be wronged for 20 years, and there is also the kind of injury that he was used by his best friend.

"Xiao Bowen is one of the four people who appeared in the room!" The butcher sighed heavily and laughed, pale and helpless, as if self-deprecating.

The butcher slowly straightened up from his chair and glanced at me.

"Give me a cigarette."

With the butcher's current physical condition, I wouldn't give it to him in normal times, but I know how uncomfortable he is now, Yun Duruo and I glanced at each other, seeing that she nodded silently to me, presumably she can also understand the butcher's pain at the moment.

I handed the cigarette to the butcher's hand, took out a lighter and lit it, the butcher put the cigarette to the corner of his mouth blankly, and said in a low voice without moving.

"It seems that Xiao Bowen has planned it from the beginning, and I am also the most important part of his plan."

"Don't blame yourself too much, Xiao Bowen deliberately arranged all this, even if you calculated that you wouldn't notice his existence." Yun Duruo handed the water over comfortingly.

"Du Ruo, you are the best at case restructuring, although it was a case twenty years ago, but you know no less about this case than I know, so you can reorganize the whole process." The butcher lit the cigarette at the corner of his mouth and said weakly.

"The four people who appeared in Mu Hanzhi's room that night were Xiao Bowen, Xiang Zhongyi and Nian Weimin, and the woman who is still unclear, judging from the bloodstains found at the scene, the four of them quickly had an argument with the deceased Mu Hanzhi after entering the room, and the woman among the four attacked the back of Mu Hanzhi's head with a vase, causing Mu Hanzhi to die on the spot."

Yun Duruo said this, and continued with some hesitation.

"As for the role of the other three in this murder, it is not yet known."

"Nian Weimin was responsible for disposing of Mu Hanzhi's body, it was he who put Mu Hanzhi's body into the bathtub and dumped sulfuric acid corrosion, while Xiang Zhongyi was controlling Mu Xiaoxuan at that time." I suddenly remembered what I had seen that night when Mu Hanzhi touched my body.

"Why do you infer that?" The butcher looked at me and asked seriously, and Yun Duruo also looked at me curiously.

"Nian Weimin went home to dispose of the bloody clothes after the incident, which shows that he had contact with Mu Hanzhi's corpse, and Nian Weimin's major is chemical engineering, he can get sulfuric acid and also knows how to use sulfuric acid to dispose of corpses." It is impossible for me to tell Mu Hanzhi that he has seen me, so I can only speculate based on the case. "And the shape of Nian Weimin being placed after his death implies that he is a human-faced beast, so it is not difficult to see that Nian Weimin disposed of Mu Hanzhi's body with sulfuric acid at that time."

The butcher nodded thoughtfully, and it seemed that he agreed with me.

"In this way, the form of Xiang Zhongyi's death can also reverse the role he played at that time, Aunt Tan said that Xiang Zhongyi has a cowardly personality, he can't do anything to destroy the corpse, and Mu Hanzhi will definitely cry when Mu Xiaoxuan is attacked, so he controlled Mu Xiaoxuan at that time." Yun Duruo habitually clasped his hands and said slowly. "Xiang Zhongyi is not a vicious person, but his participation in the murder shows that he was manipulated, which is why he was made into a marionette after his death, implying that he was a puppet!"

Finally, Xiao Bowen ......, "The butcher now has a deep disappointment on his face whenever he mentions this name." What role does he play? ”

"He is the most important and critical link in this murder case, and without him, the case of Mu Hanzhi jumping off the building could not have been faked as a suicide." I took the butcher's words and said calmly.

"Go on." The butcher took a deep puff of cigarette, perhaps because he was too hard, inhaled into his lungs and coughed violently, the wrinkles on his face were pulled deeper, and he seemed to be much older and haggard in an instant.

"If you want to create the illusion of suicide, you must let Mu Hanzhi and Mu Xiaoxuan fall downstairs in front of everyone, this is the most powerful illusion, which is why Mu Xiaoxuan was not killed at that time, but the problem is that once someone is found to have jumped off the building, someone will inevitably go to the roof to save people, so if there are people on the roof, then the judgment of Mu Hanzhi committing suicide is to be discussed, and the best way is that someone must prove that there is no one on the roof of the building where Mu Hanzhi jumped off the building."

"I ...... I'm the best proof of that. The butcher sneered weakly.!

"That's right! There's no stronger evidence than a police officer's testimony, and Xiao Bowen knows that you will have people cordon off the scene so that no one will come in or out and there will be no chance for people to appear on the rooftop, and his goal is to make you instill in the belief that there is no one on the roof all along. I nodded.

"So everything was rehearsed in advance, call the police, calculate the time when I arrived at the scene, and then push down Mu Xiaoxuan when I arrived, let me preconceive that the fall from the building started at that time......," the butcher took a deep breath of cigarette and said slowly.

"Then when you come up, push Mu Hanzhi's corpse down." Yun Duruo took the butcher's words and sighed.

I lit a cigarette for myself, and after a moment of silence looked at the exhausted butcher, and said in a low voice.

"They need a suicide case without flaws, they need an invisible person who can deal with Mu Hanzhi's corpse, and Xiao Bowen is so familiar with you, so familiar that you completely ignore his existence, he is the most perfect invisible person...... Xiao Bowen has been hiding behind the door, you go up to the roof to check around to make sure there is no one, but you ignore the back of the door, because you would never think that there will be someone hiding there, when Xiao Bowen waits for the right time, quietly walks out from behind the door and stands in front of you, you will not feel that anything is wrong......"

A friend asked why the characters in Fang Shi came out with only a few strokes, and I am grateful again that you can still remember those characters who have accompanied everyone after a year, Fang Shi tells the legend of Qin Yanhui, and Tanling writes the story of Rong Yan, and they themselves are inextricably linked.

The real reunion will have to wait until the third volume, a total of six volumes, with Rong Yan exploring his own life experience as the main line, arranging for him to gather with others in the third volume because at that time he has the ability to keep pace with these predecessors, and the more he will face in the future, it will no longer be an ordinary investigation
