The three of them went downstairs, and Mr. Fang stuffed a business card and drove away.

There is only a name and a string of phone numbers on the business card, and there is no general name for this and that.

It's like a horse wins, ugly and distinctive, walking on the road is a humanoid business card, and what about horse dung, few people know what it looks like.

"He's not in the same system as me, nice people. Zheng Kai smiled and enthusiastically hooked Yang Fan's shoulder, "Let's go, eat first." ”

The road is not far, three hundred meters from the entrance of the community, and a large green vehicle is parked. On the carriage, several green typing are extremely conspicuous: urban cleaning.

Before I got closer, there was a rotten smell on the surface of the car, and it was ten miles into the wind.

"What do you think, isn't it mysterious, are you interested in building a fire? Zheng Kai banged on the back door of the car according to the fixed rhythm.

"Yes, low-key and flamboyant, sure enough, there is a set. Yang Fan gave a thumbs up, and a gust of wind blew, and the smell was disgusting.

Awesome, it's quite similar to the ground. With such a peaceful environment in the country, it is really blind to put all kinds of nameless things.

Yang Fan thinks that it is the second disease attack of the otaku on the side, and he likes to play mysteries and the like, even if it is an ordinary truck in front of him, who knows.

"Ha, I don't know how to do it. As soon as my car is parked, no one will post the order, and it will not be towed away, which saves money and reduces trouble. ”

The back door of the carriage opened, Zheng Kai jumped on first, and said, "Come up." ”

Yang Fan followed, and when he entered inside, he realized that it was another world entirely. It is a space of about 30 square meters, and there are many devices on both sides that have never been seen before, and various indicators are flashing.

The car is equipped with an air circulation system and a purification system, although it has a bit of an outside smell, but it is not serious. The indoor temperature is very pleasant, and there is no feeling of dryness.

Two men and a woman, both busy with the work at hand.

"It's not in vain. Yang Fan said.

Zheng Kai took out a folding long table from the corner and set it up in the middle, and the other three moved chairs and gathered in front of the table.

"Peaches, have you taken the takeaway?" Zheng Kai said.

A woman with a big cake face opened a cabinet, large and small horse clip bags, and put them on the table.

"Come, eat, eat, and talk about work. ”

Yang Fan's feet shook, almost unsteady on his feet, and he thought that there was a big meal, but he didn't pay attention to it, as if the food was similar to his own, and he was also a government worker.

The five of them worked together, unpacked the packaging, put the dishes and chopsticks, and Zheng Kai said, "Do you want to drink? ”

didn't say a fart, Yang Fan was really hungry, so he quickly picked up disposable chopsticks and ate it, seven or eight dishes, and enough rice was delivered. Not bad.

"Don't you think it's strange that the quality of the food is low?" Zheng Kai said a lot and patiently explained, "We don't like to waste time very much, and we don't know how to drink, so we can't go to the restaurant." An hour for a meal, it's better to doze off. ”

Yang Fan noticed that the four of them had heavy dark circles under their eyes, and they yawned when they had a meal, and they recognized it a little, and they were not used to going to restaurants, so it was good to eat enough.

"You must wonder why you are allowed to look at this? To test that there are many in some bureaus, our department is still a bit famous to the outside world. ”

"Why?" Yang Fan pondered, putting the secret in front of him, the other party's intentions were so deep.

"You know why, but you won't admit it. Regardless of the test results, I think you should join us, it's a good fit. ”

Zheng Kai enthusiastically sandwiched a piece of meat for Yang Fan, who pretended to be flattered, and then started haha, and said: "You are too polite, your department is too high-end, I can consider it after studying for a few years." ”

"I knew it was going to be like this. Zheng Kai's eyes narrowed, as if he inadvertently mentioned, "On the evening of January 23 this year, we included you in the list of major suspects, and now, you are no longer major, 99%. ”

The topic was too sudden, Yang Fan couldn't help but have chopsticks in his hand, this expression was taken into Zheng Kai's eyes, patted Yang Fan on the shoulder and said, "Nonsense, eat." ”

"What is Brother Zheng talking about?" Yang Fan's heart sank, and if he tried it again, he would definitely go through the gangs, what should he do. There are also polygraphs.

Since the other party said that he has this equipment, he is to make himself worried and restless, and he is afraid that he will not be able to hide it at all.

"I'll tell you about the accuracy and principle of the lie detector. Some people in the United States say that he can achieve an accuracy rate of 96%, but in fact it is only between 64% and 71%, don't have a psychological burden, I believe you can avoid it. ”

Zheng Kai smiled brightly, his eyes stared at the expression on Yang Fan's face, and said: "Start from the four aspects of blood pressure, heart rate, breathing and skin resistance, when I ask some sensitive topics, you must refrain from it, take a deep breath, and try to ......calm your mind as much as possible."

Zheng Kai's explanation echoed in his ears, but Yang Fan did not feel relaxed, but became more nervous, and applied pressure before he started the test.

It's a battle of hearts.

It is necessary to fight back.

Yang Fan interrupted the other party with a wave of his hand, the golden light in his eyes skyrocketed, and he calmly replied: "Brother Zheng's information has expired." The accuracy rate of the message I received was about 35%. ”

"Brother Zheng, you just walked on the road with 20 breaths per minute, and now you eat 17 times, which is normal. The outside is hot, the inside is cool, and the pulse is diastolic and skewed. What about the heart rate, you ask me questions, I will definitely be sensitive if I am interested, the skin resistance is dry here, and the measured is equal to not being measured......"

"That's a good point. Zheng Kai smiled, interesting, and took the lead in clapping, "Applause, wonderful, really wonderful explanation, the lie detector is worthless, better than ordinary people." ”

The leader spoke, and the three of them couldn't put down their chopsticks, and followed with a loud applause, and the food in their mouths continued to chew.

Zheng Kai looked at Yang Fan, the two looked at each other, and at the same time realized the deep and endless wisdom in each other's hearts.

Zheng Kai lamented: "But Yang Fan, I'm afraid it won't work these few times." You may not understand, polygraphs are conducted for two or three hours, and your body has not adapted to the environment here for such a long time, and I don't want to explain it. ”

Will it be so kind? Yang Fan's heart sank even more, and said, "How can you conclude that I'm lying?" After all, it's only 35% accurate. ”

"It's okay, we're patient, and if we don't work once, we'll do it a few more times. Zheng Kai smiled even more, "It just so happens that you are on summer vacation, and it is also very empty, as long as it is different once or twice, you can unilaterally think that you are lying, so you have to confess, Yang Fan." ”

"I don't even know what to confess, just wait for the test results. "Yang Fan has used his brains vigorously, it has been identified, and there is a little problem that must be targeted.

There is no way to hide, it is human, it is impossible to test almost the same result every time, unless the machine.

"How do you make yourself a machine-like being? ”

The human body is controlled by the brain, and the brain signals the signals sent at a fixed frequency.

This path is feasible, but it is not capable enough to detect brain waves.

Yang Fan recalled his own means, the pen was useless, the harmonica could be hypnotized, and it couldn't last for a few hours, ruled out.

I remember that when the data eye first appeared, it was the closest time I was to the machine, and the system also prompted me to either concentrate or distract.

"Concentrate, disperse, right, disperse. ”

Thinking of this, he almost screamed, and finally found that glimmer of light.

"Let your brain consciousness be divided, form two thinking individuals, one to deal with questions and tests, it is estimated that 18% of the brain domain is used, the human body is sluggish and rigid, and the physiological index can be maintained for a long time. ”

"The other 82% can be used as a bystander and give advice. Similar to two personalities. ”

Absolutely.

Yang Fan smiled lightly, then let's try, who is stronger.
