Before, Zhao Yu had read the polygraph manual carefully. It turns out that although this polygraph is accurate, it can only make judgments on clearly pointed questions. That's why he asked Liu Pengfei to answer with a simple "yes" or "no".
When he turned on 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 was laid out like a kindergarten sketch.
However, watching the time passing by, Zhao Yu took the time to start asking his questions.
Since it was his first time using it, Zhao Yu had no experience, so he asked the simplest question: "Are you a man?"
"yes!"
Although he looked confused, Liu Pengfei still cooperated and gave 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?" Zhao Yu asked again in order to verify the accuracy.
"no!"
The green light flashes.
"Well..." Zhao Yu wanted to verify the effect of lying, and hurriedly discussed with Liu Pengfei, "Brother, I'll ask you again, this time you say yes, okay?"
Zhao Yu's words left the onlookers, Monk Zhang Er, confused.
"Are you a transgender?" Zhao Yu opened his mouth to ask, then pointed at Liu Pengfei and reminded him in a low voice, "Say 'yes' and hurry up!"
"Well..." Liu Pengfei was sweating on his forehead and nodded slightly tremblingly as he replied, "Yes!"
As a result, the red light not only turned on, but also beeped!
There is drama…
Zhao Yu sighed in his heart. It seemed that there was really nothing wrong with this lie detector!
"Okay, the test is over, let's officially start!" 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 puzzled. How could anyone tell a criminal not to tell the truth? I really don't understand, what on earth does he want to do
"Hurry up!" Zhao Yu looked at the time gradually decreasing and asked hurriedly, "Is your name Liu Pengfei?"
"yes!"
Green light.
"Are you from Muguantun, Li County?"
"yes!"
Green light.
"Do you like rice cakes?"
"no!"
Green light.
"Your parents are divorced?"
"no!"
Green light.
"Have you ever had hemorrhoid surgery?"
"Has a lady ever said that you're 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 notice was that under Zhao Yu's guidance, he answered questions faster and faster!
Unexpectedly, as Zhao Yu kept asking, the conversation suddenly changed and he asked quickly:
"Do you know Yu Zhigen?"
When he first heard the words "Yu Zhigen", Liu Pengfei 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 understood 70% to 80% even without using a polygraph. It seems that Liu Pengfei and Yu Zhigen really know each other!
"Yes!" After a three-second pause, Liu Pengfei finally said the answer, but he also realized his cowardice, so he looked very nervous.
Green light.
"He and I are from the same hometown, and we played together when we were young..." Liu Pengfei began to explain. However, the more he explained, the more problematic it seemed.
"I said, you only need to answer yes or no, there is no need to say anything else!" Zhao Yu reminded him. This time, Liu Pengfei felt even more guilty and sweat was already forming 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 felt instinctively that there was something to it.
In addition, she was also very curious about Zhao Yu's novel and unique interrogation method. What is the origin of this Zhao Yu...
"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 turned on.
Because there were photos as evidence, Zhao Yu had long known that there would be such a result, and Liu Pengfei definitely knew Lin Meifeng.
"Have you ever been to Fumin Community 10 years ago?" Zhao Yu continued to dig deeper.
After hearing the words "enriching the people's 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 violent shouting, Liu Pengfei quickly shook his head and replied: "No!"
Beep... the red light is on.
Damn... Even though he only asked a few simple questions, Zhao Yu's whole body was shocked. Oh my god... Could it be that... the truth of the murder case is right in front of you!
Zhao Yu thought about it for a while and then went directly to the topic:
"Do you know about the massacre in Fumin Community 10 years ago?"
"Well... yes!" Liu Pengfei nodded, and wanted to add, "I just heard about it," but before he could open his mouth, Zhao Yu shouted loudly:
"Tell me! Yu Zhigen, did you kill him!?"
"No, no, no!?" Liu Pengfei was so frightened that his face turned pale and he shouted three times in a row.
However, the polygraph results are unmistakable!
Beep... the red light is on!
Wow!
Grandma is a bear...
Zhao Yu suddenly widened his eyes and felt 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 murder case from him, but who knew... the real culprit of the murder case! The real murderer who has disappeared for 10 years... is actually right in front of you! !
The surprise came so suddenly that Zhao Yu was not prepared at all. He was silently stunned for a long time, and then he remembered that the time for the polygraph test was coming soon.
So, he suppressed his shock and continued to ask: "Liu Pengfei, was it raining heavily the day you killed Yu Zhigen?"
"No!" Liu Pengfei became a little anxious and said hurriedly, "Officer, what do you mean? Why do you ask so many incomprehensible 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 so anxious that he kept rubbing his back against the seat, as if he didn't want to cooperate anymore.
Zhao Yu was equally impatient, watching as time waited for no one. He simply jumped up, rushed from the table to Liu Pengfei, and grabbed his collar fiercely.
At that time, the other three police detectives were frightened, fearing that Zhao Yu would do something excessive, and hurriedly stepped forward to pull him.
Unexpectedly, at this moment, the door of the interrogation room suddenly opened, and Miao Ying quickly entered from the outside, shouting at the same time to stop the three police detectives.
"You guys go out first!" Miao Ying waved to them, and the three police detectives quickly left the interrogation room.
Zhao Yu saw Miao Ying coming in and thought she was here to disrupt the situation. Who knows, to his surprise, Miao Ying also came to 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 cowardly 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 closed!"
Miao Ying's brief words made Liu Pengfei shudder.
"Officer, if you have something to say, say it well, say it well, and I will cooperate! Cooperate!"
Zhao Yu looked at Miao Ying in surprise and didn't quite understand what medicine she bought in the gourd. She was so cooperative with me, wasn't she trying to lure me into beating up the suspect so that she could frame me
snort!
Am I that stupid
Zhao Yu let go of Liu Pengfei's collar and asked, "Speak quickly! Are you and Lin Meifeng having an affair?"
"No!" Liu Pengfei finished his answer, but added, "Sir, I really can't understand what you said?"
As a result, the green light on the lie detector flashed first, and then beeped again and the red light turned on.
oh…
Zhao Yu understood that there was indeed no adultery between Liu Pengfei and Lin Meifeng, but when he said he didn't understand what I said, he was really lying!
The murderer of the massacre—it was him! ! !
