Jiang Bai pondered for a moment: "That recording, can you let me listen to it?" ”

Hearing this, Liu Zifeng wanted to refuse.

But after thinking about it, Jiang Bai has won awards on the show, maybe there is something outstanding.

"We have investigated Xu Yong based on your suspicions, and it turns out that he has a good alibi."

"Your enthusiasm for helping the police solve the case is commendable, but I need a strong reason to listen to the recording."

Jiang Bai understood what he meant, and sorted out his thoughts.

"The four of us are roommates, and when I went back today, I found that Xu Yong's mood was very wrong."

"But in fact, he has been in this state for several days, although Xu Yong is usually not very gregarious, but it is too abnormal."

"I just paid attention to it and noticed that he left the dormitory with a summary of the experiment in his hand."

Jiang Bai paused and took a deep breath: "That experiment was done by Xu Yong and the counselor together. ”

"He used to work with counsellors to complete experiments, but his name didn't appear on the summary every time."

"At first, I didn't feel at ease, until the counselor was killed, which aroused my suspicions."

After listening to Jiang Bai's analysis, Liu Zifeng rubbed his stubble and thought for a moment.

"According to what you said, Xu Yong's suspicion is indeed very big."

Jiang Bai quietly waited for his next step.

He Dazhuang and Du Yiheng looked at each other, and they didn't know what to say.

Liu Zifeng thought about it, made a decision, and took out Xu Yong's voice recorder from his body.

"Let's make it clear first, there is no truth about the case, no one should chase after the wind and spread it around, understand?"

The three of them understood the importance of the matter and nodded solemnly.

Liu Zifeng nodded, and in front of the three of them, he pressed the play button.

Recording playback ......

There was the sound of an expert giving a lecture, and a few subtle noises.

Jiang Bai frowned and listened with his ears pricked up, unwilling to miss any detail.

The devil is in the details!

Suddenly.

Hear a certain point in time.

Jiang Bai picked up the recorder and put it to his ear to repeat the clip just now.

Startled a few people, Liu Zifeng almost couldn't help but snatch it back.

However, seeing Jiang Bai's serious expression, he forcibly retracted his hand again.

Once, twice, three times......

Twenty times past.

Jiang Bai raised his head, his gaze swept over the three of them, and said very firmly.

"This recording is a forgery."

Several people were stunned and looked at him in disbelief.

Liu Zifeng squinted his eyes and said in disbelief: "Are you sure? ”

Jiang Bai did not argue, but chose to speak with facts.

He turned up the volume of the recorder to the maximum and motioned for Liu Zifeng to put it in his ear and listen.

"Do you hear a very noticeable squearing sound in this clip? There was also a pause. ”

"I don't know how much you know about the voice recorder, Xu Yong's voice recorder is HKUST SR901."

"The price is in the thousands, and with this kind of professional-quality voice recorder, it is impossible to have the situation just now."

Liu Zifeng's eyes were shocking, as if he had thought of something, and he said with an idea: "Synthesis? ”

Jiang Bai nodded: "That's right, this recording shouldn't have been recorded with this recorder." ”

"To be precise, it was Xu Yong who put his original recording in this recorder in order to use SR901 to play a fake sound quality."

He Dazhuang stammered: "This ...... How is this possible? Why did Xu Yong do this? ”

Jiang Bai didn't speak, and looked at Liu Zifeng.

Liu Zifeng nodded knowingly, but before he had time to explain, he got up and was about to rush out.

Suddenly, Jiang Bai got up and stopped him: "I hope ...... During the interrogation, you can let me come. ”

Hearing this, Liu Zifeng's face showed embarrassment: "You are a supernumerary, you can't participate in the interrogation work......

But as if he thought of something, Liu Zifeng didn't dare to guarantee: "I'll try it, but whether the leader approves it or not, I don't dare to guarantee it." ”

"Thank you!" Jiang Bai nodded at him gratefully.

Leaning against the wall, Jiang Bai's outline of Xu Yong involuntarily appeared in his mind.

He didn't know how to describe his current mood.

……

Half an hour later, Jiang Bai reappeared at the police station.

It's just that this time I didn't come as the person being questioned.

Instead, he participated in this trial as a criminal investigation consultant.

In the dimly lit interrogation room, Xu Yong sat in the suspect's special seat, his head bowed, not knowing what he was thinking.

Liu Zifeng said that when Xu Yong was arrested, he was very calm and seemed to have expected something.

Not noisy or noisy, very cooperative to get into the police car.

Jiang Bai secretly regretted: "Xu Yong, I didn't expect us to meet in this way. ”

Xu Yong glanced up, and quickly lowered his head again, saying nothing, his eyes revealing a will to die.

Jiang Bai took a deep breath and began the interrogation.

"Why did you kill the counselor?"

Seeing that Xu Yong was silent, Jiang Bai changed the question: "Do you hate him?" Or did he do something to you that you couldn't accept? ”

Xu Yong was still silent.

"Is it because of the experiment report? But you used to ......"

Hearing the four words of the experiment report, Xu Yong suddenly became excited and clenched his fists.

Raising his reddened eyes, he gritted his teeth and said, "He should be damned!" ”

But Xu Yong only said these three words, and then he died down.

Liu Zifeng next to him was secretly anxious, glanced at Jiang Bai, and asked him with his eyes if he wanted to change himself?

Jiang Bai shook his head slightly, and continued: "According to your character, even if your name is not added to the experiment summary, it will not make you murderous, right?" Is there something else going on here? ”

"Like what he did, what he said, or what did you see?"

As if recalling something bad, Xu Yong stood up from his chair at once, but his body shook back because his hands were cuffed.

He didn't seem to feel the pain, and roared, "Ah! Don't say it, I told you to stop it, I've confessed my guilt, what else is there to say? ”

The best inquiry is to break down the other party's psychological defenses.

Jiang Bai seized this opportunity and told all the previous counselors' oppression of Xu Yong.

Although Xu Yong angrily accused and insulted him, he still did not stop.

After about five minutes, Xu Yong suddenly broke down and cried, holding his head in his hands, lying on the small table of the chair, crying silently.

"What do you know? You don't know anything. ”

"He's not human, he's a demon, he's sent from heaven to torture me."

"Every one of his research results is mine, and I made it alone, but I don't even deserve a name."

"I wanted to report him, but he threatened me with my mother's poor health, saying that as long as I dared to do that, he would expel me from the school, my mother's health has always been bad, and she can't accept this kind of thing."

Speaking of this, Xu Yong raised up, with a sad smile on his face.

"But my mom died a week ago."

"He can't threaten me anymore, I'm not afraid of him anymore, I'm going to send him to hell."

The truth of the matter has come to light.

Jiang Bai and Liu Zifeng glanced at each other, and they both felt the other party's suppressed anger.
