Early the next morning, there was a knock on the door of Yu Zhe's house.

"Morning~"

Twilight pursed her lips and chuckled, putting her hands behind her back, pretending to be mysterious, not knowing what she had taken it.

"Morning, you're ......"

Yu Zhe looked Shi Dusk up and down, and she didn't look like she was going to the store.

"Give you 'special training' today!Teach you 'lying'~"

Shi Duluo smiled, walked straight into Yu Zhe's house, and threw what looked heavy on the table.

It was a large black metal suitcase with silver trim and a combination lock on both sides, reminiscent of a cash box full of money when two organizations were trading in a movie.

Yu Zhe sat next to Shi Duluo and watched her open the box with interest,

It is said to be a box, but it is actually a "precision instrument" that can be lifted as a box, with more than a dozen wires in it, staggered and complex, and a screen above it, I don't know what it does.

Shi Duluo was engrossed, carefully checking each line, and linking it to the machine in order, so that Yu Zhe did not bother with his serious appearance.

Finally, after more than ten minutes of debugging, the screen of the machine lit up, which was roughly divided into three parts, like the screen of the hospital electrocardiogram, but each part is now a straight line.

"It's successful!" Shi Duluo clapped his hands happily, and then stretched out with his hands in fists, and before Yu Zhe could ask, he took all kinds of small objects connected to the instrument and tied Yu Zhe up with five flowers.

"What is this?" Yu Zhe let Shi Duluo "do whatever he wanted", but seeing that there were more and more things tied to his body, he finally asked with doubts.

"This is a lie detector~ Mo Lin got it yesterday, of course I came to try it today~" Shi Duluo said as he spoke, and the movements in his hands did not stop.

"I see you're pretty good at using things. Yu Zhe quipped, looking at Shi Duluo's busy appearance, he felt a little cute.

"It's also the first time I've tried to use it on someone else, and it's been used on me before. Shi Duluo pursed his lips, and after pasting the last two lines on Yu Zhe's head, he quickly returned to the screen, saw that the values had changed, and smiled happily, "OK, it's done." ”

Yu Zhe leaned over curiously, and the three lines on the screen really fluctuated, but he couldn't understand the meaning.

"Na~" Shi Dusk hooked the corners of his mouth, learning the appearance of the "domineering president" in the TV series, and gently picked up Yu Zhe's chin with his fingertips, "The interrogation begins~ Yu Zhe's prisoner confesses strictly~ Resist leniency ~"

"Just ask, the warden, I won't tell you the truth. Yu Zhe chuckled and said with Shi Duluo.

Shi Dusk retracted for a second, folded his hands on the table, his expression was serious, his eyes were fixed on Yu Zhe's eyes, he cleared his throat, and spoke.

"Name!"

"Yu Zhe. ”

Twilight first asked a few regular questions, looking at the polygraph's values while asking, and seeing that the three lines were moving steadily, she began the next stage. 、

"You are thinking of a number from 1 to 10 in your head right now, don't tell me which one it is. ”

"I figured it out. Yu Zhe didn't know Shi Duluo's intentions, so he could only do as she said.

"I'm going to say a few random numbers, you can choose to say 'yes' or 'no', of course you don't need to be honest every time, I'll guess the numbers you think based on the data, understand?"

"Understood. Yu Zhe thought that Twilight would ask a lot of substantive questions, but he didn't expect it to be such a simple test, he felt that it was not difficult, he just needed to make a fool of himself and mess up Twilight's judgment.

"Is it 3?" Twilight went straight to the point, in order to make it more difficult for herself, and to make the first test easier for Yu Zhe, she decided to judge by only looking at the screen data, and try to avoid looking at Yu Zhe directly.

After all, she had seen Yu Zhe's ability to lie, it was really ...... Indescribable.

"It's not. ”

"Is it 6?"

"Yes. ”

"What about 4?"

"Yes. ”

A few questions, Yu Zhe thought that the answers were fluent, and it was not too difficult to say "yes" or "no" at will.

"That'...... Is it 7?"

Its real-time twilight has already gotten the answer, but it still asks an extra number for insurance.

"Yes. ”

"Alright, you're thinking '4', right?" Twilight replied easily.

"Huh?" Yu Zhe's expression was enough to show that Twilight had guessed correctly.

Twilight turned the screen to Yu Zhe, and after a few simple steps, the values and recordings of the questions he had just asked began to play back.

Yu Zhe carefully observed that when he asked the first few questions, the values were stable, but when he answered the question of "6", his heart rate, breathing, and even the tension of his muscles changed more or less, and when he answered the question of "7", it was the same.

"How so...... I didn't feel any change in my body when I said it......" Yu Zhe felt a headache and didn't know why this was happening at all.

"Probably because you still have a lot of rejection of the act of 'lying' in your heart, so there will be some subtle reactions that you are not even aware of. ”

Shi Duluo spread her hands, saying that she actually didn't know much about it and didn't understand the principle.

"Again, I don't believe it. Yu Zhe refused to admit defeat and hoped to regain some "face" through another test.

"Okay, but this time the rules will be changed, I will be from small to large, and you will answer no to all the numbers. ”

Twilight turned the screen back in front of her and said again.

"Ready. Yu Zhe repeatedly paralyzed herself, trying not to think about the twilight voice, no matter what she said, just answer "no".

Twilight spoke very slowly, ensuring that every note could reach Yu Zhe's ears clearly, and the ten numbers were asked for a full minute and a half.

In the end, after asking all the questions, Shi Duluo chuckled and sighed and said, "It's five, right?"

“…… Why?!" Yu Zhe asked in disbelief, feeling that he had done his best.

He watched the screen replay again, and Twilight fell to the side to explain to him.

"You see, when I ask the first two numbers again, your heartbeat is very slow, but after the third number, it starts to gradually fluctuate and grow, and when I ask four, you are the most nervous, and when I ask about four, you recover more than half of it, until it returns to its original state, and every number after that, you don't change anything. ”

"Then shouldn't you be suspicious of four?" Yu Zhe looked at the data, still unable to understand.

"Anyway, according to common sense, you should be nervous about the previous number, like ...... The teacher answers the questions by name according to the student number in class, and the most nervous thing is not to call you, but to call the person in front of you. ”

Shi Duluo thought of an example to explain the problem to Yu Zhe.

“……”

Yu Zhe was a little desperate, and he couldn't pass the simple test.

"Don't be discouraged, maybe it would be nice to practice more. ”

Shi Duluo comforted Yu Zhe on his lips, and he was also desperate in his heart, if he couldn't do it to this extent, what would he do with the real interrogation at that time.

"When questioned by the police...... Would you really use this thing?"

Although Yu Zhe has met the police many times, he has never entered the police station, and he has only seen the interrogation from TV series, and in his impression, the police will not make such bells and whistles.

"No, it won't. Twilight replied.

“…… That...... Why do you want to test it. Yu Zhe was shocked, feeling that this was completely useless.

"Hey...... You can't even fool the machine, and you still want to fool people. Twilight chuckled as she cupped her cheeks.

"It's harder to fool the machine......"

"No, the machine is dead, it just reflects the changes in your body truthfully, as long as you do enough self-paralysis, it is just a pile of scrap metal, useless, and people can make judgments by observing your expressions and demeanor and other aspects, so an experienced person can better see if you are lying than a machine. ”

“……”

Although Yu Zhe didn't refute anything, he was obviously suspicious of Shi Duluo's words, so in order to convince him of "losing", Shi Duluo directly closed the lid of the machine, raised his eyebrows, and looked at him with affection.

"So let's try again, the same test, this time I don't look at any data, how about it?"

Yu Zhe nodded, acquiesced to this proposal, and fully prepared in his heart.

In the next fifteen minutes, they tried a total of five times, and as expected, Yu Zhe "failed".

"How's that~ do you want to continue?" Twilight chuckled.

"Forget it......" Faced with the result, Yu Zhe even began to doubt life, is his thoughts really so easy to see through......

Shi Duluo turned on the machine and played back the data from the five tests to Yu Zhe one by one.

To his surprise, in fact, as the number of tests increased, the ups and downs of his body data were shrinking, and by the fourth time, it had become very insignificant, and the fifth time, there was basically nothing abnormal.

"So, it's much easier to deceive a machine than to deceive a person. ”

In the face of the facts, Yu Zhe had no choice but to compromise and asked Shi Duluo, "Then what should I do?"

"Fooling the machine is only the first step, and then I will make up a rough story for you, all you have to do is to keep it in mind during this time, and narrate it in the right tone and demeanor, and then you can be asked directly. ”

Twilight hasn't finished talking yet, things can't be so simple.

"But everything can be variable, and I can't do it all, so there's a good chance you'll need to play on the spot...... This...... You can do your best, as long as you don't overdo it...... There should be no problem. ”

Yu Zhe took a deep breath, it was worthy of a commission of 200,000 yuan, which was indeed more challenging than the previous ones. ”

"Don't worry, I can, tomorrow I will be better than today. ”

"Tomorrow?" Shi Duluo tilted his head and blinked, his long eyelashes stirring up and down, "What are you thinking, our 'interrogation' today hasn't officially started yet~"
