Chapter 511 Polygraph

  Yuan Cheng and the others were stunned, they didn't expect the relationship between Shu Ran and Gu Xiuyun to start like this.

   "I still remember that on the second day of the Lu family's marriage with the Gu family, Gu Xiuyun's lace news spread all over the place, and was photographed leaving the hotel with a hickey early in the morning. Could it be at that time that you had an affair with this woman?"

  Monkey said with a smile.

In the interrogation room, Gu Xiuyun was still questioning, "If you don't love me, why did you give me the bar?"

"That was given to me by your father. When I was with him, I said that I wouldn't give him a penny or a dime. I'll give it back to him, but he doesn't want it, so I'll just give it to his son. s things."

   After Shu Ran finished speaking, it was not surprising to see that Gu Xiuyun's eyes changed towards her.

   "Don't make the mistake of thinking that when I'm with your dad, I want to marry into your Gu family. It's my business to love him, and marriage is another matter. I'm me, and your family is a family."

  Gu Xiuyun sat down again, "What's the matter with Buling San? You are actually selling Buling San in a bar, are you crazy?"

  Shu Ran was stunned, "What is Buling San? Gu Xiuyun, what nonsense are you talking about? Why would I touch that kind of thing?"

  Yuan Cheng and others waited for a long time, and finally came to the most crucial question. They stared at Shu Ran's expression on the screen for a long time, but did not find any flaws.

   "Monkey, that's enough, go and try Shuran." Yuan Cheng said.

  Monkey nodded, and just after taking two steps, Yuan Cheng added, "Get on the lie detector."

"okay."

   When the interrogation was over, Si Xiyou's side just ended. At this time, he was a little tired, and his white shirt was still stained with blood, which looked terrifying.

   "Second uncle."

  Si Niannian hurriedly walked over, and while supporting him, he held his wrist to make sure that his pulse was fine, then he was relieved.

   "Second Uncle, go to my store to change your clothes before going home." Si Niannian said.

  Si Xiyou nodded, "Alright, save your grandparents from worrying."

   Yuan Cheng came over and said, "Director, I'm sorry, because it's a big deal, so there are a little more questions and it takes up a lot of your time."

   "It's okay, it was originally related to our research institute, you should ask clearly." Si Xiyou expressed his understanding.

  Yuan Cheng didn't see anything at all, and asked another question, "Director, the lie detector of our Detective Bureau was originally a product of your research institute. I would like to ask, how accurate is this thing?"

   When it came to professional issues, Si Xiyou immediately became serious.

"Under normal circumstances, it is about 87.65%, and the error will not exceed 0.3%, but the specific situation also varies from person to person, because Director Yuan should also know that people are the most cunning and fickle in this world. No matter how high-tech these instruments are, It was also created by man."

   "What kind of person can avoid the polygraph detection?" Yuan Cheng asked again.

  Si Xiyou knew that he was facing a problem, "If Director Yuan doesn't mind, you can show me the video of the interrogation just now."

   "This is of course the best."

   Yuan Cheng quickly took a few people to his office, and Si Niannian and Bu Chensu naturally followed.

After watching Shu Ran's reaction in the video, Si Xiyou came to the conclusion, "This is a woman with a very high dual quotient, and her self-control is very strong. Her heartbeat only fluctuates a bit when she mentions Gu Cheng, or It's because she really loves Gu Cheng, or she knows about Buling Powder, but she didn't do it, the real seller of Buling Powder is..."
