Before, Zhao Yu had read the instructions of the lie detector carefully. It turned out that although the lie detector was accurate, it could only make judgments on the specific points. Therefore, he asked Liu Pengfei to only answer simple "yes" or "no".

When Zhao Yu turned on the switch of the invisible lie detector, 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 entire picture layout is like a simple drawing of a kindergarten.

Seeing the passage of time, Zhao Yu seized the time to start his own question.

Since it was the first time to use it, Zhao Yu had no experience and asked the simplest question as soon as he opened his mouth: "Are you a man?"

"yes!"

Although he showed doubts, Liu Pengfei still cooperated to give the answer.

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

oh……

It seems that the green light should represent the truth.

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

"no!"

The green light flashes.

"That..." Zhao Yu wanted to verify the effect of lying, so he quickly discussed with Liu Pengfei, "Brother, I'll ask you again. Is it okay if you say yes this time?"

Zhao Yu's words made the bystanders confused.

"Are you a transgender person?" Zhao Yu asked, and whispered to Liu Pengfei, "Say 'yes', hurry up!"

"Well..." Liu Pengfei nodded slightly with sweat on his forehead and replied, "Yes!"

As a result, the red light not only illuminated, but also sounded beeping!

Yoxi...

Zhao Yu sighed in his heart, it seems that this lie detector is really fine!

"Okay, the test is over, and next, we'll officially start!" Zhao Yu signaled to Liu Pengfei, "You don't need to tell the truth. Just answer yes or no, and answer quickly. Do you understand?"

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

Miao Ying and the police detectives were also confused. How could they tell the criminals that they could not tell the truth? I really don’t understand what he wants to do?

"Hurry up!" Zhao Yu looked at the time gradually decreasing, and hurriedly asked, "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.

"Have your parents divorced?"

"no!"

Green light.

"Have you had hemorrhoid surgery?"

"A lady has said that you are not good at that aspect..."

...

Zhao Yu asked more than a dozen irrelevant but painful questions in one breath. Although Liu Pengfei couldn't figure out why Zhao Yu asked this question, he answered them truthfully.

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

Unexpectedly, Zhao Yu asked, and suddenly changed his mind and asked quickly:

"Do you know Yu Zhigen?"

When Liu Pengfei heard the three words "Yu Zhigen", he was obviously stunned for a moment and did not answer immediately.

Zhao Yu had been waiting for his reaction for a long time. At that time, he didn't need a lie detector, and he also understood 70% or 80%. It seems that Liu Pengfei knew Yu Zhigen indeed!

"Yes!" After pausing for three seconds, Liu Pengfei finally gave the answer, but he also realized his timidity, so he seemed very nervous.

Green light.

"He and I were fellow townsmen. I played together when I was a child..." Liu Pengfei began to explain. However, the more he explained, the more problematic he seemed.

"I said, you just need to answer yes or no, and there is no need to say anything else!" Zhao Yu reminded him. At this moment, Liu Pengfei felt even more guilty and sweat was already on his forehead.

At this moment, Miao Ying, who was surveillance in another room, was also very surprised. Although she didn't know who Yu Zhigen was, she had already instinctively felt that there was a lot of articles here.

In addition, she was also very curious about Zhao Yu's novel and unique way of interrogation. What is the origin of this Zhao Yu...?

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

This time, Liu Pengfei paused again before answering: "No!"

Beep... The lie detector rang and the red light lit up.

Because there are photos as evidence, Zhao Yu had known that such a result would be there, and Liu Pengfei definitely knew Lin Meifeng.

"10 years ago, have you been to Fumin Community?" Zhao Yu continued to dig deeper.

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

"What are you looking at? Answer quickly!"

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

Beep...the red light is on.

Damn... Although I only asked these few simple questions, Zhao Yu was shocked by it. I'm so obedient... Could it be that... the truth of the murder case is right in front of me!?

Zhao Yu thought about it for a while and then rushed to the topic:

"Do you know the murder case in Fumin Community 10 years ago?"

"Well...yes!" Liu Pengfei nodded, and wanted to add, "I just heard of it," but before his mouth opened, Zhao Yu shouted loudly:

"Say! Yu Zhigen, did you kill him!"

"No, no, no!?" Liu Pengfei was so scared that his face turned pale, and he shouted three times in one breath.

However, the results of the lie detector will not be wrong!

Beep...the red light is on!

Wow!

Grandma, bear...

Zhao Yu suddenly widened his eyes and felt a little dazed. In fact, although he suspected Liu Pengfei in front of him, he only thought that he could get clues of the murder case from him, but who knew... the real murder case! The real murderer who had disappeared for 10 years... was right in front of him!!

The surprise came so suddenly that Zhao Yu was not prepared at all. He was stunned for a long time before he remembered that the time for the lie detector was about to come.

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

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

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

"Stop talking nonsense!" Zhao Yu continued, "I'll ask you, do you have an affair with Lin Meifeng?"

"What!" Liu Pengfei was anxious and kept rubbing the seat with his back, as if he didn't want to cooperate anymore.

Zhao Yu was also impatient, seeing that time was not waiting for anyone. He simply furiously rushed from the table to Liu Pengfei, and grabbed his collar.

At that time, the other three detectives were shocked and afraid that Zhao Yu would do excessively, so they rushed forward and pulled him.

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

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

When Zhao Yu saw Miao Ying coming in, she thought she was here to disrupt the situation. Unexpectedly, what surprised him was that Miao Ying also came to Liu Pengfei and stood side by side with Zhao Yu, one left and one right.

Suddenly, when he saw the two demon kings standing in front of him with fierce eyes, Liu Pengfei swallowed his saliva with timidity, and his whole body shivered as if he was touched with electricity.

"Comrade Zhao Yu, don't worry!" Miao Ying clenched his fists and clattered, "All surveillance facilities have been closed!"

Miao Ying's short sentence made Liu Pengfei shudder.

"Police officer, please say it well, and say it well, I will cooperate! Cooperate!"

Zhao Yu looked at Miao Ying unexpectedly, not quite understanding what she bought in the gourd? She cooperated with me so much, wouldn’t she want to seduce me to beat the suspect and frame me?

snort!

Am I that stupid?

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

"No!" Liu Pengfei finished answering, but added, "Sir, I really don't understand what you are saying?"

As a result, the green light flashed on the lie detector first, and then another beep, and the red light lit up.

oh……

Zhao Yu understood that Liu Pengfei and Lin Meifeng did not have an affair, but he said he couldn't understand what I was saying, but he was lying in a real way!
