All-round mathematician

Chapter 177

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

There are only names and a series of phone numbers on the business card, without this or that general name, Diaosi thinks it is very high-end.

It's like Ma Ying, who is so ugly that he looks like a business card when he walks on the road, but when he walks on the road, few people know what he looks like.

"He and I are not in the same system. He's a nice guy." Zheng Kai smiled and warmly hooked Yang Fan's shoulder, "Let's go, let's eat first."

Not far from the road, 300 meters from the entrance of the community, there is a large green vehicle parked.On the carriage, a few green words are extremely conspicuous: city cleaning.

Before approaching, there was a rotten smell on the surface of the car, facing the wind for ten miles.

"What do you think? Is it very mysterious? Are you interested in starting a fire?" Zheng Kai knocked on the back door of the car in a fixed rhythm.

"That's right, low-key and ostentatious, sure enough." Yang Fan gave a thumbs up, and a gust of wind blew by, the smell made people sick.

It's awesome, it's quite similar to pretending.With such a peaceful environment in the country, all these unnamed things are really blind.

Yang Fan thinks that the otaku next to him is suffering from a second-year middle school illness, and he likes to play mysteries. Who would know that there is an ordinary truck in front of him.

"Ha, you don't know how to do it. Once my car stops, no one will post the ticket, and it won't be towed away. It saves money and trouble."

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

Yang Fan followed and entered inside, only to realize that it was a completely different world.This is a space of about 30 square meters, with many unseen equipment placed on both sides, and various indicator lights flashing.

The car is equipped with an air circulation system and a purification system. Although there is a little smell from the outside, it is not serious.The indoor temperature is very suitable, without feeling hot and dry.

Two men and one woman are busy with the work at hand.

"It's time to increase your knowledge, it's not in vain." Yang Fan said.

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

"Taozi, did you get the takeaway?" Zheng Kai said.

A woman with a big pie face opened a certain cabinet, and put various vest bags, large and small, on the table.

"Come, eat, and talk about work after eating."

Yang Fan's feet swayed, and he almost couldn't stand still. He thought he was going to have a big meal, but it didn't matter. It seemed that the food was similar to his own, and he was considered a government employee.

The five of them worked together, unpacking, and setting out the bowls and chopsticks. Zheng Kai said, "Want to drink? There's none here."

No fart, Yang Fan was really hungry, so he quickly picked up disposable chopsticks and ate, seven or eight dishes, and the rice was enough.good.

"Do you think it's strange that the quality of the food is low?" Zheng Kai talked a lot, and explained patiently, "The few of us don't like to waste time, and we don't know how to drink, so we don't have to go to a restaurant. One meal lasts for an hour. Might as well doze off."

Yang Fan noticed that the four of them had dark circles under their eyes, and they yawned after eating a meal, so he admitted that he was not used to going to restaurants, as long as he was full.

"You must be wondering why you are asked to read these? To test the fact that there are many in some bureaus, our department is still a bit famous to the outside world."

"Why?" Yang Fan pondered, keeping the secret in front of his eyes, the other party had deep intentions.

"You understand the reason, but you certainly won't admit it. No matter what the test result is, I think you should join us, which is very suitable."

Zheng Kai enthusiastically gave Yang Fan a piece of meat. The latter pretended to be flattered, and then he laughed and said, "You are too polite, and your department is too high-end. I can consider it after a few years of study."

"I knew it would be like this." Zheng Kai narrowed his eyes and seemed to mention it unintentionally, "On the night of January 1 this year, we included you in the list of major suspects. Now, you are no longer a major suspect, but 23%."

The topic was too sudden, Yang Fan couldn't help eating with chopsticks, this expression caught Zheng Kai's eyes, he patted Yang Fan's shoulder and said: "Nonsense, eat."

"What is Brother Zheng talking about?" Yang Fan's heart sank.And a lie detector.

Since the other party said that he had this equipment, he just wanted to make himself nervous and restless, and he was afraid that he couldn't hide it.

"While I'm free, let me tell you about the accuracy rate and principle of the polygraph. Some people in the United States say that its accuracy rate can reach 96%, but in fact it is only between 64% and 71%. Don't There is a psychological burden, I believe you can escape."

Zheng Kai smiled brightly, fixed his eyes on the expression on Yang Fan's face, and said again: "Starting from the four major aspects of blood pressure, heart rate, respiration and skin resistance, when I ask some sensitive topics later, you must restrain yourself. Take a deep breath and try to calm your mind..."

Zheng Kai's explanation echoed in his ears, but Yang Fan didn't feel relaxed, but became more nervous, and exerted pressure before the test started.

This is a battle of the mind.

Must fight back.

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

"Brother Zheng, your breathing was 20 times per minute when you were walking on the road, and now you are eating 17 times. The change is normal. The temperature outside is high, the inside is cool, and the pulse diastole has deviation. As for the heart rate, you ask me questions, I am interested It will definitely be more sensitive, and the skin resistance is dry here, so if you measure it, you won’t be able to measure it..."

"Well said." Zheng Kai smiled, was interesting, and took the lead in clapping his hands, "Applause, applause, wonderful, really wonderful explanation, the lie detection is worthless, better than ordinary people."

When the boss spoke, the three of them couldn't put down their chopsticks and applauded loudly, continuing to chew the food in their mouths.

Zheng Kai looked at Yang Fan, their eyes collided, and at the same time, they felt the deep and endless wisdom in each other's heart.

Zheng Kai lamented: "But Yang Fan, I'm afraid it won't work just a few times. You may not understand that the polygraph test takes two to three hours. Your body hasn't adapted to the environment here for such a long time. I think it's okay to release the water." It’s hard to explain.”

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

"It doesn't matter. We are very patient. If you can't do it once, just do it a few more times." Zheng Kai smiled even more, "It just so happens that you are on summer vacation, and there is a lot of vacancy. As long as there is a difference once or twice, it is entirely possible to unilaterally think that you I lied, so be honest, Yang Fan. We really don’t mean any harm to you, we just want to know some technical information.”

"I don't know what to confess. Let's wait for the test results." Yang Fan used his brains wantonly, and he has already been identified, and he has to deal with any minor problems.

There is no way to hide, as a human being, it is impossible for the test results to be almost the same every time, unless it is a machine.

"How to make yourself a machine-like existence."

Human body actions are controlled by the brain, which generates signals and sends them at a fixed frequency.

This path is feasible, but the current ability is insufficient to detect brain waves.

Yang Fan recalled his own methods, the pen was useless, the harmonica could hypnotize him, but he couldn't last for a few hours, so he ruled it out.

I remember that when the data eye first appeared, when I was closest to the machine, the system also reminded me to either concentrate or disperse my energy.

"Concentrate? Disperse? Yes, divert your energy."

Thinking of this, he almost screamed out, and finally found that ray of dawn.

"Split one's brain consciousness to form two thinking individuals, one to deal with questions and tests, and an estimated 18% of the brain area is used. The human body is dull and rigid, and the physiological index can be maintained for a long time."

"The other 82% can be regarded as a bystander and make suggestions. It is similar to two personalities."

Absolutely.

Then try to see who is stronger.
