Chapter 99: The Magical Lie Detector

Before that, Zhao Yu had read the instruction manual of the lie detector carefully. It turned out that although the lie detector was accurate, it could only make judgments on clear-cut questions. That's why he asked Liu Pengfei to only answer a simple "yes" or "no".

When Zhao Yu turned on the invisible polygraph, a simple picture immediately appeared in his mind: a red light, a green light, and a 10-minute countdown in the upper right corner. The layout of the whole picture was like a kindergarten stick figure.

Watching the time go by little by little, Zhao Yu seized the time and started asking questions.

Since it was the first time to use it, Zhao Yu had no experience, so he asked the simplest question: "Are you a man?"

"yes!"

Although he was puzzled, Liu Pengfei still gave the answer cooperatively.

As a result, the green light in Zhao Yu's mind flickered.

oh……

It seems that the green light should represent the truth.

"Are you a woman?" Zhao Yu asked again to verify the accuracy.

"no!"

The green light is blinking.

"That..." Zhao Yu wanted to verify the effect of lying, so he quickly discussed with Liu Pengfei, "Brother, let me ask you again, this time you say yes, okay?"

Zhao Yu's words made the onlookers Monk Zhang Er puzzled.

"Are you a transsexual?" Zhao Yu opened his mouth to ask, then pouted at Liu Pengfei, reminding him in a low voice, "Say 'yes', hurry up!"

"Hmm..." Liu Pengfei nodded tremblingly with sweat on his forehead, and replied, "Yes!"

As a result, the red light not only turned on, but also beeped!

well……

Zhao Yu sighed in his heart, it seems that there is nothing wrong with this lie detector!

"Okay, the test is over, and now we're officially starting!" Zhao Yu signaled to Liu Pengfei, "You don't have to tell the truth, you just need to answer yes or no, and answer quickly, do you understand?"

"Ah? What?" Liu Pengfei was a little confused.

Miao Ying and the police detectives were also baffled. How could they tell the criminals not to tell the truth? I really don't understand, what is he trying to do?

"Hurry up!" Zhao Yu watched the time gradually decrease, and asked hastily, "Is your name Liu Pengfei?"

"yes!"

green light.

"Are you from Muguantun, SL County?"

"yes!"

green light.

"Do you like rice cakes?"

"no!"

green light.

"Your parents divorced?"

"no!"

green light.

"Have you had hemorrhoid surgery?"

"Did a lady tell you that you are not good at that..."

...

Zhao Yu asked a dozen innocuous but painful questions in one breath. Although Liu Pengfei couldn't figure out why Zhao Yu asked such questions, he answered them truthfully.

However, what he didn't realize was that under Zhao Yu's guidance, his speed of answering questions became faster and faster!

Who knows, Zhao Yu asked, and suddenly changed the subject, and asked quickly:

"Do you know Yu Zhigen?"

When he first heard the word "Yu Zhigen", Liu Pengfei was obviously taken aback, but did not answer immediately.

Zhao Yu had been waiting for his reaction for a long time. At that time, even without a lie detector, he understood 70% to 80% of it. It seems that this Liu Pengfei really knew Yu Zhigen!

"Yes!" After a pause of three seconds, Liu Pengfei finally said the answer, but he also realized his timidity, so he looked very nervous.

green light.

"He and I are from the same town. We played together when we were young..." Liu Pengfei began to explain. However, the more he explained, the more problematic he seemed.

"I said, you just have to answer yes or no,

Needless to say anything else! "Zhao Yu reminded, this time, Liu Pengfei was even more guilty, and sweat was already breaking out on his forehead.

At this moment, Miao Ying, who was watching in another room, was also very surprised. Although she didn't know who Yu Zhigen was, she already instinctively felt that there was a lot to it.

In addition, she was also very curious about Zhao Yu's novel and unique interrogation method. What is this Zhao Yu... exactly?

"Do you know Lin Meifeng?" Zhao Yu continued.

This time, Liu Pengfei paused again before replying, "No!"

Beep... The lie detector beeped and the red light came on.

Because of the photos as evidence, Zhao Yu knew that there would be such a result. Liu Pengfei definitely knew Lin Meifeng.

"Ten years ago, did you go to Fumin Community?" Zhao Yu continued to dig deeper.

After hearing the words "Fumin Community", Liu Pengfei suddenly realized something, and immediately looked at Zhao Yu with wide eyes, showing great shock and fear.

"What are you looking at? Answer quickly!"

Under Zhao Yu's shouting, Liu Pengfei quickly shook his head and replied, "No!"

Beep...the red light is on.

Damn...Although he only asked such a few simple questions, Zhao Yu was taken aback by it. I'm so obedient...Could it be that...the truth of the massacre is right in front of you! ?

Zhao Yu pondered for a while, then went straight to the topic:

"Do you know about the massacre in Fumin Community 10 years ago?"

"Yes... yes!" Liu Pengfei nodded, and wanted to add, "I just heard about it," but before he opened his mouth, Zhao Yu asked loudly:

"Speak! Yu Zhigen, did you kill him!?"

"No, no, no!?" Liu Pengfei turned pale with fright, and shouted three nos in one breath.

However, the results of a lie detector can never be wrong!

Beep...the red light is on!

Wow!

grandma bear...

Zhao Yu's eyes widened suddenly, feeling a little dazed. In fact, although he had doubted Liu Pengfei in front of him, he only thought that he could get clues to the massacre from him, but who knew... the real culprit of the massacre! The real culprit who disappeared for 10 years...is right in front of him! !

The surprise came so suddenly that Zhao Yu was not prepared for it. He was stunned for a long time in silence, and then he remembered that the time for the polygraph test was about to come.

So, he suppressed his shock and continued to ask, "Liu Pengfei, was it raining heavily the day you killed Yu Zhigen?"

"No!" Liu Pengfei was a little anxious, and hurriedly said, "Officer, what do you mean? Why do you ask so many inexplicable questions?"

However, the red light on the lie detector was still on.

"Stop talking nonsense!" Zhao Yu continued, "Let me ask you, are you having an affair with Lin Meifeng?"

"What!" Liu Pengfei was in a hurry, rubbing his back against the seat, as if he didn't want to cooperate any more.

Zhao Yu was also impatient, watching the time wait for no one. He just jumped violently, rushed from the table to Liu Pengfei, and grabbed his collar fiercely.

At that time, the other three police detectives were shocked, fearing that Zhao Yu would do too much, so they hurried forward and pulled him.

Unexpectedly, at this moment, the door of the interrogation room suddenly opened, Miao Ying quickly entered from the outside, and at the same time stopped the three police detectives loudly.

"You go out first!" Miao Ying waved at them, and the three detectives quickly left the interrogation room.

When Zhao Yu saw Miao Ying coming in, he thought she was here to disrupt the situation. Who knows, to his surprise, Miao Ying also came in front of Liu Pengfei, standing side by side with Zhao Yu.

Suddenly seeing the two demon kings standing in front of him with fierce eyes, Liu Pengfei swallowed timidly and trembled as if he had been electrocuted.

"Comrade Zhao Yu, don't worry!" Miao Ying clenched her fists loudly, "All monitoring facilities have been shut down!"

Miao Ying's brief sentence gave Liu Pengfei a shock.

"Officer, if you have something to say, speak up, speak up, I will cooperate! Cooperate!"

Zhao Yu looked at Miao Ying unexpectedly, not quite understanding what kind of medicine she bought in the gourd? She is cooperating with me so that she is trying to lure me to beat the suspect so that she can frame me, right?

snort!

Am I that stupid?

Zhao Yu let go of Liu Pengfei's collar and asked, "Quickly tell me! Are you and Lin Meifeng having an affair?"

"No!" Liu Pengfei finished his answer, but added, "Sir, I really don't understand what you're talking about?"

As a result, the green light flashed on the polygraph first, and then, there was another beep, and the red light turned on.

oh……

Zhao Yu understood that Liu Pengfei and Lin Meifeng did not have an affair, but he was lying when he said he didn't understand what I said!

The murderer of the massacre—it was him! !
