Siheyuan: With a system in place, you don’t need to worry in times of famine

Ye Fei went straight to the police station with the polygraph.

He already knew that everyone in the courtyard took Jia Zhang to the police station last night.

I just happened to sign in today and got a lie detector to test whether what Jia Zhang said was true or not.

"Captain Zheng."

"Ye Fei, you are here."

“Are we going to interrogate Jia Zhang today?

Can I join in?"

Ye Fei directly stated his purpose, which made Zheng Lu stunned.

Although he had made an exception and let Ye Fei take the lead in investigating the human traffickers, he felt that it would be better to have someone with experience in interrogation.

Ye Fei has many ways to find out information, but in terms of professionalism, it is definitely these people who will do it.

"Do you want to sit in on the class?"

Zheng Lu opened his mouth in confusion. It was only a moment ago that he was distracted.

Judging from Ye Fei's personality, he would definitely not take on a job for no reason.

When it comes to finding information, Ye Fei may be a little better than them, but in other aspects, Ye Fei does have shortcomings. That is why the people in the investigation team are all elite soldiers sent by him.

"I want to try this."

Ye Fei took out a mini lie detector from his bag, which was about the size of an old cell phone.

"what is this?"

After taking a closer look at the thing in Ye Fei's hand, even though Zheng Lu had seen many things, he couldn't tell what it was.

"Polygraph."

"What?"

Zheng Lu asked again subconsciously, could this thing be what he understood it to be? !

"What do you think this is?"

"A lie detector can detect whether a person is lying."

Ye Fei had no doubt about the authenticity of the polygraph. After all, it was the system that was used, so how could there be any problems?

"Just such a small thing?

Can you also detect whether a person is lying?

How can it be? ! "

Zheng Lu said without hesitation:

"Comrade Bai Ling has studied micro-expression psychology. She can tell whether a person is lying based on the subtle changes in his or her facial expressions.

And such a small thing can be more powerful than a human?!"

"How about we test it first?"

Ye Fei was not too surprised to see that Zheng Lu didn't believe it.

After all, lie detectors had not yet appeared in this era, and people solved cases and conducted interrogations entirely by observing micro-expressions.

"Okay, how do I test it?"

“I ask the questions, and you answer them.

If you tell a lie, this lie detector will react."

"Okay, you can arrange it."

Seeing Ye Fei so confident, Zheng Lu became extremely curious about the lie detector and began to cooperate without hesitation.

"Zheng Lu, age."

"41."

"Are you henpecked?"

"Not afraid."

As Zheng Lu finished speaking, the polygraph began to beep. A trace of guilt flashed through Zheng Lu's eyes:

"What does it mean?"

"It means you lied."

Ye Fei smiled calmly and said jokingly:

"It seems that Captain Zheng is still henpecked."

"What do you know?!

Husbands who are afraid of their wives can always be successful! "

Zheng Lu looked at Ye Fei with dissatisfaction, with a hint of warning in his eyes:

"Ye Fei, this is just a small test. You can pretend you know nothing about some things."

"Understood, Captain Zheng."

Ye Fei nodded and continued to ask:

"Captain Zheng, what underwear are you wearing today?!"

"???"

Zheng Lu looked at Ye Fei's face full of gossip and ridicule, and couldn't help but want to blow Ye Fei's head off, but because he was in the test, he had to answer honestly:

"Red."

"Oh, so Captain Zheng likes red."

Zheng Lu......

Ye Fei asked several more questions in succession, and some of Zheng Lu's answers were deliberately wrong, and they were all detected by the polygraph, which instantly gave Zheng Lu a new understanding of the polygraph.

“Are lie detectors really that accurate?

Let me ask you instead."

As Zheng Lu spoke, he began to prepare and asked all the questions that Ye Fei had just asked, one by one.

"Captain Zheng, how about this lie detector? Do you think it's OK?"

After finishing the test, Ye Fei asked directly.

“So far, the accuracy rate is quite high.

Ye Fei, you have quite a lot of new and interesting things."

Zheng Lu sighed:

"Let's go and interrogate Jia Zhang now."

After bringing Jia Zhang to the interrogation room, Ye Fei started the lie detector test directly.

When Jia Zhang saw that it was Ye Fei, she didn't care about their previous relationship in the courtyard. She seemed to have found a life-saving straw and begged bitterly:

"Ye Fei, please save me, I am not a human trafficker at all, you should know that.

We have lived in the same courtyard for so many years, how could I be a human trafficker? !

Please help me explain this to the police comrades..."

"You can only know a person's face but not his heart. I'm not tied to you every day, so who knows what you did secretly?!"

As soon as Ye Fei opened his mouth, Jia Zhang was almost so angry that she vomited blood.

"I knew you were all in the same group, just trying to frame me."

When Jia Zhang heard Ye Fei's cold and ruthless words, she instantly became furious and spoke without thinking.

"Tsk, you really think you're a dish."

Ye Fei spoke again, and Zheng Lu frowned:

"Ye Fei..."

Ye Fei nodded. Even though he had never interrogated anyone before, he had seen it on TV. During the interrogation, other irrelevant topics could not be discussed.

"Jia Zhang, originally named Jia Cuihua.

Next I have a few questions for you. You must answer them honestly. If you confess, I will treat you leniently. If you resist, I will treat you severely. Do you understand? !"

Zheng Lu spoke up and brought the topic straight to the point. Jia Zhang looked at Zheng Lu's face, which was dark and serious. She nodded subconsciously and swallowed.

"Comrade police officer, just ask me, I will definitely cooperate."

"Okay, then let me ask you, did you take Xiaodang with you when you went out yesterday?"

"Yes."

"So what did you take Xiao Dang to do?"

"I'm picking up rags. Our family's situation is quite special. I want to pick up some rags to exchange for some money to spend."

Jia Zhang hastily explained that at this moment, there was no point in saving face. She just had to answer the questions honestly, and maybe that way she could be let go sooner.

"Did you deliberately leave Xiaodang there without caring about?!"

"No, at that time an old woman snatched away the things we picked up. I went to catch her and didn't pay attention to Xiao Dang..."

Jia Zhang hurriedly shook her head and answered truthfully.

"According to what you said, you went to catch the person who stole your things, so how did you know that Xiaodang and Lou Xiao'e were together?"

As soon as Zheng Lu asked this question, Jia Zhang couldn't help but feel a little nervous:

“I saw it with my own eyes.

After I came back, I found Xiaodang was missing, so I immediately looked for him and found that Xiaodang had left with Lou Xiao'e.

I thought since I had someone to help me look after the child, it would be much more convenient for me, so I just left it alone..."
