Chapter 187 There is a reason not to let her go (3 more)
The room looked a little familiar.

Lie detector.

Gu Yi'an has seen this thing quite a few times, but it's the first time for him to fight in person.

Seeing the scene here, she couldn't help but smile wryly.

If it is an ordinary person, of course there is no way to escape the lie detector.But for her, for those who have been trained, lie detectors simply don't work for them.

In fact, it is easier to understand with a very simple statement.

Many instruments of the polygraph are linked to the human body to measure the heartbeat, pulse, blood pressure and the like.

First, through a set of simple questions, such as asking the subject's name, gender, age, etc., let the subject tell the truth, and use this to measure the subject's physiological curve.

Then ask questions that require lie detection. If the subject is telling the truth, then his physiological curve will coincide with the previous physiological curve, and will be consistent. Even if there is a difference, it is a subtle difference.But if the subject told a lie, his physiological curve would change greatly.

Of course, there is another method now, which is to test brain waves, but this is more troublesome.

The principle used by this lie detector is that when a person tells the truth and a lie, his brain reacts differently, which will also cause changes in his heartbeat, blood pressure and pulse.

And if you want to deceive the lie detector, you only need to have the ability to do both.You are telling a lie, but you have to tell your brain that what you are telling is the truth, convince yourself that the lie is the truth, or convince yourself that the truth is a lie, after deceiving your brain, you will It also tricks your physiology and gives you different results on a lie detector.

It is difficult for ordinary people to do this, but for professionally trained personnel, it must be done.

And Gu Yi'an knew very clearly that he could do this.

Now, these methods are about to be used on her, Gu Yi'an is a little helpless.

She was very relaxed, because she had nothing to hide, or rather, she wanted to know what happened at that time more than the case investigators!
The room was very quiet, except for Gao Yang, there was only one man wearing glasses.

That man's temperament is very gentle, very elegant, and a gentleman.

When Gu Yi'an saw him, he knew that he was the one in charge of the test.

Her eyes flicked past him, and then she lay down on the test bench as required.

The man came over and connected her to the wires of various instruments.

"My name is Mu Zhuo." The man's voice was clear and refreshing, with a slight smile.

Gu Yi'an nodded, "It suits your name very well."

"Thank you for the compliment." Mu Zhuo smiled, "These may be a little cold on your skin, but it will be fine soon."

Gu Yi'an hummed, but didn't say much.

Mu Zhuo smiled again, "You don't look nervous at all."

"Should I be nervous?"

"Perhaps."

After some meaningless conversation, everything is connected.

"Gu Yi'an, right? May I call you An'an? Let me ask you two questions first, test the instrument, and we'll start later, okay?"

Mu Zhuo is very polite, and will explain every move carefully, which will indeed give people a sense of peace of mind.

But Gu Yi'an couldn't feel at ease now.

She has certain doubts about this Mu Zhuo.

"Okay, my first question is, your name is Gu Yi'an, isn't it? Answer me yes or no."

Mu Zhuo's voice was still very flat, without any personal emotional factors.

"Yes." Gu Yi'an's voice was also very calm.

"Are you a doctor?"

"Yes."

"Do you like being a surgeon?"

"Yes."

"Very good, the test is over, there is no problem with the instrument." Mu Zhuo said with a smile, "Then we will officially start, you still answer me yes or no, there is no need for other answers, understand?"

"Ah."

"Gu Yi'an, do you know the deceased Hong Chengang?"

"Yes."

"The deceased is dead, are you happy?"

"Yes."

"You think the deceased deserved more than death."

"Yes."

"You have a hatred for the dead."

"Yes."

"You killed the dead?"

"……do not know."

"Please answer yes or no."

"……no."

drip...

The alarm sounded, which meant that Gu Yian's physiological curve had undergone a major change.

Gao Yang's face changed slightly.

For the first time, he looked at the weak so-called expert in front of him.

In the transcript, when asked whether she had killed someone, Gu Yi'an's answer was indeed that she didn't know.This question confuses the police.

But now, during the lie detection process, Mu Zhuo asked her if she had killed someone, and she answered no, the siren went off, which meant that she might have lied on this question.Gao Yang knew very well that if Gu Yi'an really didn't know whether she killed someone or not, then during the lie detection process, no matter whether she answered yes or no, the siren would sound.

However, she couldn't answer yes, that would be tantamount to admitting that she had killed someone.She can only answer no.

But when the answer was no, the siren sounded, which meant that she was lying when she said that she didn't kill someone... Then speaking from the absolute negative meaning, wouldn't it mean that she was telling the truth if she killed someone?

Although the result of the polygraph test cannot be submitted to the court as evidence, it is enough to use this result to apply for the detention of Gu Yi'an!

Gao Yang's eyes are quite complicated.

As a criminal policeman, he hopes to solve the case as soon as possible, but from another aspect, he also hopes that Gu Yi'an is innocent and can be exonerated as soon as possible.

So today is the last day of detention, and he is really conflicted.He didn't feel comfortable letting people go or not letting them go.

But now, he really got a chance to not let him go, and he felt even more uncomfortable.

The Q&A continues.

"Mo Yunxiu is Bo Yi's wife?"

"Yes."

"Bo Yi doesn't know about your relationship with Mo Yunxiu."

"Yes."

"You don't want Bo Yi to know about your relationship with Mo Yunxiu."

"Yes."

"You don't want to see Mo Yunxiu."

"Yes."

"On the day when the crime happened, Mo Yunxiu called you and told you not to tell Bo Yi. You actually didn't want to tell Bo Yi in your heart."

"Yes."

"The disappearance of Mo Yunxiu has something to do with you."

"……I have no idea."

"Please answer yes or no."

Mu Zhuo's voice was as calm as ever.But Gu Yi'an was already dripping with sweat.

"……no."

Didi, the alarm sounded again.

Gao Yang's brows were already wrinkled enough to kill a fly!
