Cui Lingfeng looked at Li Yao, pointed to one of the intricate crystal brain and magic weapon units behind him, and said, "I'd like to ask Professor Rhode to help me have a look at this" lie detector ", just like you just analyzed this tracking and positioning magic weapon, to completely disassemble and analyze it."

Li Yaowei was stunned. Before he asked, Cheng xuansu, the head of the secret police beside him, was stunned and said, "speaker, what does that mean?"

Her expression is quite shocked, it seems that Cui Lingfeng's decision is temporary, even the most intimate secret police chief, did not know in advance.

Cui Lingfeng said faintly: "today is the most important trial. We can't keep captain Tang in secret for too long. There is more and more turmoil outside. If we delay, the whole firefly will be in chaos!"

"We have to come to a conclusion as soon as possible, that's why I'm here in person to talk to captain Tang."

"However, your interrogation a few days ago has not found an answer. Captain Tang's performance is impeccable. I've been thinking about which link has gone wrong. Until today, I even use a lie detector against the captain of the firefly in the face of the world's great injustice."

"But is it possible that the polygraph has been tampered with for a long time? If we can't find the problem with the lie detector, we will be very passive! "

Cheng xuansu's eyes flashed by with a strange look and said: "experts from the Ministry of internal affairs have carried out a comprehensive examination of this lie detector. There is absolutely no problem! They are all experts who are proficient in this field, and Professor rod is not good at this field. He is an outsider at all. "

"I value Professor rod as an outsider!"

Cui Lingfeng said decidedly, "xuansu, have you ever thought about how deep his tentacles would be if captain Tang had really become an immortal long ago, and he was really playing a big game of chess? Is it possible to bribe some people in your internal affairs department, or let experts in your internal affairs department do something in the lie detector?"

"After all, Captain Tang is a technologist, and so are the experts in your interior department. Even if they are really playing tricks in the dark, it's hard for us to find out."

Cheng xuansu's face was uncertain: "this, this is impossible. I believe in the loyalty of every member of the interior department!"

"It's very likely!"

Cui Ling said coldly, "xuansu, don't underestimate our enemy. Don't you know who captain Tang is? Give him a few more years, and he'll be covering up on the firefly! What's so strange about buying off some technicians and refiners from the Ministry of interior? "

"So, I've been thinking about how to break this situation these days. The key is who can be trusted. In the end, I found the answer - some outsider!"

"Captain Tang absolutely has the ability to bribe some people in the interior department, and he absolutely has the motivation to cheat on the lie detector. All experts may be immortals. In just a few days, it's hard for us to judge who can be trusted."

"Even if we now invite an expert from the Ministry of internal affairs to come here and check the lie detector on the spot, if he has been an immortal for a long time, he can still hide the truth in front of us."

"Professor Rhode is different. Before Captain Tang was arrested by us, he was completely an outsider and had nothing to do with the key magic weapon such as" lie detector. "

"The idea of asking him to check the lie detector was just when I saw his analysis report. I didn't tell anyone the idea until Professor Rhode stood in front of me, so there was no risk of leakage. You all thought that he was just explaining the little blood red bead."

"So, as long as captain Tang doesn't have the power of foretelling, how can he know that Professor Rhode will be involved in this matter, and how can he bribe Professor Rhode?"

"Besides, didn't you go to Professor rod last time to conduct a detailed investigation on him and confirm that he had nothing to do with Captain Tang and that he was loyal to the Republic of Xinghai? He's not the best person. Who else? "

Cheng xuansu turned his face, and a cold sweat oozed from the half of his forehead that Cui Lingfeng couldn't see: "but Professor Rhode doesn't know anything about polygraph."

"I don't know anything about it."

Cui Lingfeng looked at Li Yao's hands and said with a smile, "I believe that there is always something to be figured out when the technique of refining weapons has reached the highest level. The difficulty of analyzing such a large lie detector is much lower than the magic weapon of tracking and locating the size of rice grains. Show Professor Rhode the manual of refining and maintaining this lie detector. Even if his judgment is really flawed, I'm willing to make a bet!"

"What do you say, Professor rod?"

Cui Lingfeng, Cheng xuansu, and many other secret police and staff around him all stare at Li Yao with complicated eyes.

Li Yao tilted his head and thought for a while, then said in a long tone: "you can try it, but I need time to read the manual of the manufacture and maintenance of this lie detector, and there is no guarantee that I will find the problem."

"Never mind, I can wait."

Cui Lingfeng gestured to Cheng xuansu, "give Professor rod all the information related to this lie detector, and then help him make a pot of good tea. It's said that Professor rod likes to drink" green dragon ball ", right?"

"It's the purple dragon ball."

Li Yao said without raising his eyelids.

"Do you want to protect Professor rod to go back and get his special refining equipment?"

Cheng xuansu asked in a low voice, "all the master craftsmen have their own instruments and magic weapons."

"If Professor rod needs any magic weapon, just ask someone to help him get it."

Cui Lingfeng sat down in front of Li Yao, like a mountain of immobility, "but Professor Rhode must stay here. He can't leave my sight for a second, so as not to be attacked."

"It doesn't matter."

Li Yao glanced at Cheng xuansu, waved his hand and said, "those ultramicro engraving knives I used to use don't need in such a big magic weapon as lie detector. Just help me prepare the supporting maintenance and testing tools for this lie detector.

"Yes

Cheng xuansu nodded heavily, like a folded knife.

Li Yao got five jade slips and studied them for half an hour.

For the precious half an hour, speaker Cui, who is supposed to be working hard every day, has been sitting in front of him, his meaningful eyes sweeping over every staff member in the secret room from time to time.

If there is a cultivator hiding here, he will see the flaw in his eyes!

Half an hour later, Li Yao estimated that it was almost time, nodded to Cui Lingfeng, moved his fingers, and began to detect the lie detector in full view of the public.

Lie detector, a magic weapon, is an "old friend" with him. In the past, on Tieyuan star, he cleverly used the weakness of an old lie detector "heart searching platform" to expose the conspiracy of Changsheng temple, quell the civil strife of Tieyuan star, and even the conflict between Tieyuan people and Feixing people.

At that time, the "information platform" was played up to be full of trials and miracles, as if no lie could escape its judgment.

However, Li Yao now knows that the so-called "lie detector" or "information desk" is only a very sophisticated magic weapon, but also has its defects and weaknesses. As long as the level is high enough and he has mastered certain skills, he will have a chance to bypass it.

No matter how advanced lie detector is, the accuracy rate is 99% at most, but it is not necessarily accurate.

And if you do something inside the lie detector, the result will be even more unpredictable.

Li Yaoping took a breath and recalled Professor rod's technique of refining the instrument. He gently opened the curved shell of the lie detector, revealing the more precise components inside than clocks and watches. Wisps of ideas sneaked into it like smoke, slowly flowing between each component and each symbol array.

Everyone was staring at him, his hands!

All of a sudden, Li Yao's hands were fixed, and then his eyes were fixed. His eyebrows shrugged and his mouth murmured. For a while, from the deepest part of the lie detector, he wrapped his mind around it and slowly took out a chip the size of a fingernail. He held it in his palm and studied it carefully for a long time.

"There seems to be no problem with the polygraph."

Li Yao told Cui Ling, "but this chip that controls the sensitivity of the lie detector has a remote control array."

"Oh?"

Cui Lingfeng's face was expressionless and didn't show any surprise or doubt, "what's the remote control?"

"It can remotely receive an extremely weak idea, the sensitivity of the remote lie detector."

Li Yao explained, "I have also dabbled in some magic weapons of lie detection and meditation in the past. The principles of these magic weapons are almost the same, or a series of physiological parameters are collected for comparison according to the changes of human heart beat, respiration, blood flow rate and facial muscles. When ordinary people tell the truth and lie, there are always some differences in various physiological parameters, such as breathing and heart beat faster, The pores contract, the pupils dilate, and so on

"However, it's very easy to cheat a strong person who can precisely control physiological parameters."

"Another way is to scan his brain waves and monitor which areas of his brain are most active when he is speaking."

"Generally speaking, when we tell the truth, especially when we recall some past experiences, we mobilize the cells in the memory area of the brain; When lying requires creativity and new ideas, different regions are mobilized - different brain active regions and different brain waves are generated, so we can judge whether it is true or not. "

"This lie detector adopts the above two principles at the same time, and the sensitivity of each sensing element, chip and symbol array is extremely high, because it must be used to deal with the most powerful people in the brain and the strongest spirits. These people's brains are solid fortresses, which are extremely difficult to break!"

"So, just a very weak, absolutely imperceptible idea can increase its sensitivity ten times, or reduce it to one tenth."

Cui Lingfeng narrowed his eyes: "so what?"

Li Yaodao said: "if its sensitivity is increased ten times, even if captain Tang is telling the truth and the brain wave is extremely amplified, it may be regarded as a lie; If the sensitivity is reduced to one tenth, it will become a dull low-level lie detector. A master like Captain Tang can easily cheat it. "
