Nishikujo Ruri led Hoshino Nana to the interrogation room, and the people she met along the way—not too many, after all, it was night, all gave way to the side of the road and bowed to Nishikujo Ruri.

And Nishikujo Ruri's face remained the same, and only a few of her older ones nodded, looking very domineering.

Seeing that Nishikujo Ruri is so majestic, Nana Hoshino's ideals can't help but waver - being a female police officer feels so powerful, and she can also have great energy, and she can tie people to a lie detector casually, which seems to be much stronger than a scholar like her mother.

But soon she threw this envy behind her, first, scientific research can determine the course of human civilization, which cannot be compared to being a policeman; second, she is not in the mood now, and Naoto Yoshihara makes her worry about death.

Nana Hoshino felt like fifteen buckets of water all the way - seven up and eight down! and like she swallowed twenty-five rats alive, which was a hundred claws scratching her heart!

Finally arrived at the interrogation room, and looked through the one-way glass wall, Nana Hoshino was suddenly furious again, pointing to the headlights and shouting, "This is abuse, right?" Just now she felt that there must be a ghost in it if she was not allowed to enter the interrogation room, sure enough!

Nishikujo Ruri looked up and said, "That's the lighting equipment." ”

"Lighting, why is he sweating all over his head?"

"He's weak, he's in a sub-healthy state, and he sweats when he sits. ”

"You ......" Nana Hoshino's favor with the police was completely ruined, and the security police were polite, and they felt like a group of bullies when they were replaced by criminal police.

Nishikujo Ruri picked a chair and sat down, patted his side, and said casually: "This is a search lesson in violence, we are facing some stubborn and vicious criminals, sometimes we need to be more ruthless and vicious than them! I said it, I will apologize for my mistake, and I will make amends, come and sit down!"

She was full of confidence and didn't lie to Nana Hoshino. In her opinion, Naoto Yoshiwara definitely has a problem - it is difficult for ordinary people to kill chickens, and people are more than ten times more difficult to kill than chickens. What's more, the man was too calm, calm like a chicken dealer who was used to killing chickens in the vegetable market.

Nana Hoshino endured it twice, went over and sat down, and looked at Naoto Yoshihara on the other side of the one-way glass wall worriedly, only to see that he was lazy like a big dog, not only did he not feel nervous, but he also shook his head and looked around from time to time.

She's even angrier! She's going to die of worry, and the stupid dog still looks like it's all right!

You're going to jail!

Soon after, two or three plainclothes officers began to attach electrodes to him and attached his hands to a sensor. Naoto Yoshihara was very cooperative, raising his hand and crooking his neck and rolling up his sleeves as people ordered, more active than the police, and asked with a shy face if he could eat two tobacco leaves to relieve his smoking addiction.

The staff saw that he was so well-behaved and smiled so brightly, and they had some good feelings for some reason, and one of them took out a cigarette and planned to light one for him, but he pointed to his nose and said that he was still recuperating from his injuries and could only chew tobacco leaves......

In the end, he succeeded, chewing tobacco leaves with a happy face.

Nana Hoshino really wanted to rush in with a dung fork and kill him with a fork, she was so angry! I really didn't want to look at him anymore, so I turned my eyes to the sensor for a moment, then looked at the main machine, and then looked at the microcomputer analyzer connected to my side.

Ruri Nishikujo noticed her gaze and introduced, "That's part of the lie detector......"

Nana Hoshino rolled her eyelids and interrupted her, and hurriedly said, "I know!"

Nana Hoshino herself is a humanoid lie detector, and after discovering her peculiarities as a child, she also spent some time researching this aspect of it - Uesugi doesn't allow her to skip grades, and she has a lot of time to spend on weekdays.

Dongying is one of the earliest countries in the world to adopt polygraphs, and Dongying people also believe in the power of electronic technology, although the restrictions on the use of polygraphs are still very strict, but once it is determined that the data can be used directly in court as indirect evidence, and even with the upgrading of technology, the credibility of the data is getting higher and higher, and some people in the judicial circle have begun to call for polygraph data as one of the direct evidence of conviction.

It's not unreasonable.

As early as the last century, scientific research pointed out that people will produce a series of physiological changes when lying, some of which are visible to the naked eye, such as changes in facial muscles, pupils, and body shape, while some are difficult to detect with the naked eye, such as abnormal respiration rate and blood volume, accelerated breathing, inhibition or breath holding, increased blood pressure, increased blood output, and changes in blood composition.

For example, there will be muscle tension, abnormal secretion of sweat glands or dry lips and tongue, confusion of brain logic, gastric contractions, abnormal secretion of digestive juices or slight vomiting and other physiological phenomena.

These physiological phenomena are caused by the stress of the autonomic nervous system, and are not controlled by human consciousness, but move autonomously, which is an instinctive conditioned reflex produced under external stimuli - consistent with the principle of Hoshino Nana's micro-expression judgment method, but Hoshino Nana is a talented person who cannot be popularized, and the lie detector can produce as much as it wants, and the two are not the same.

According to these scientific research, the polygraph, in fact, the official name should be "multi-parameter psychological side tester" - composed of transducers, amplifiers, filters, electromagnetic, light guide sensitive recorders, conduction equipment, induction equipment, computers and many other complex components, valuable and also need a group of staff to cooperate once, it can be described as a lot of labor.

Petty thieves generally don't enjoy this treatment.

With the rapid development of science and technology, polygraphs are becoming more and more precise and reliable, and the scope of use is becoming more and more extensive, and it is no longer the garbage impression left by people during the Cold War -- many people have the misconception that they can pass the polygraph as long as they are not nervous, and this is completely a dream! If the polygraph is weak like this, and the psychological quality is good, it can resist the past, then the FBI is stupid to take regular polygraph tests for every employee? Is it a waste of money for a large multinational company to require loyalty tests for important employees?

Nana Hoshino carefully observed for a while, and found that this is a polygraph that mainly detects breathing, pulse and electrodermal (skin resistance) reactions, although it is not the latest fourth-generation model, but it is also the most referential among the three generations, and is known as the most reliable one.

Suddenly, she was desperate, and it was because she understood that she was desperate -- she didn't think that human beings could hide this kind of machine that countless scientific researchers had repeatedly researched and improved! No matter how treacherous and slippery Yoshihara was, he was still a person! It was impossible for an individual to control the autonomic nerves, so he would be convicted of lying on key issues......

Although I don't know what Naoto Yoshihara has done before, but looking at his performance on weekdays, it's really a bad stomach, even if he can't get on the electric chair, then eighty percent of the prison will be worn......

In the next twenty or thirty years, will I go to prison to see him every month?

Nana Hoshino felt her muscles ache all over her body, and even her bones seemed to have lost their supporting strength. She slumped limply in her chair, powerless to stop the situation from deteriorating step by step, and could only watch as everything was ready to begin to send Naoto Yoshiwara into the bottomless abyss.

And Naoto Yoshiwara was still stupidly laughing inside, unaware of the impending catastrophe.
