I treat you like a brother, you tricked me into robbing a bank?

He wasn't surprised.

after all.

Lu Ming is an opponent with a high IQ.

If he was frightened like this, Zhou Hang's whereabouts would be exposed.

Instead, it will make him feel like a trap.

"Bring the lie detector!"

The commander-in-chief raised his eyebrows, looked at a policeman beside him and spoke indifferently.

He didn't believe that Lu Ming's psychological quality was really that strong.

Prepare to continue to interrogate Lu Ming intensively until his psychological defense is broken.

After getting the order.

A police officer quickly brought the city bureau's polygraph.

Walking into the interrogation room, clamp Lu Ming's finger with the sensor.

Then check to see if the instrument is working properly.

The principle of a lie detector is actually very simple.

when people are lying.

Often accompanied by some physiological phenomena.

And these physiological phenomena are often out of human control.

These include heart rate, blood pressure, electrical skin activity, etc.

According to the changes of these parameters, it can be judged whether the questionee is lying or not.

of course.

Lie detectors aren't [-] percent accurate either.

When meeting some extreme prisoners.

Misjudgments can also occur.

Therefore, the polygraph is generally only used as an auxiliary.

cannot be used as direct evidence.

After the policeman put on the lie detector on Lu Ming, he signaled to interrogate Lu Ming again.

"What did you eat this morning?"

The policeman on the opposite side lowered his head and spoke.

The pen in his hand was always ready to record what Lu Ming said.

His question seemed innocuous.

But it's actually a trick of using a lie detector.

That is to intersperse the questions you want to ask with some seemingly innocuous questions.

"bread!"

Lu Ming spoke very calmly.

His tone was still cold.

There was no expression on his face, like a robot.

"Where's Zhou Hang?"

The policeman quickly took down Lu Ming's answer.

Then he continued to ask questions.

"It's also bread."

Lu Ming replied without thinking.

There was no hesitation.

"Is there anything else besides bread?"

The sergeant glanced at the waveform graph on the monitor.

None of the above parameters fluctuated.

This shows that Lu Ming is very calm now.

There is no panic when lying.

"No."

Lu Ming shook his head slowly.

At this time.

The waveform graph on the polygraph display vibrates irregularly!

"You lied!"

The policeman raised his head, stared at Lu Ming and said in a deep voice.

"I drank an extra bottle of milk."

Lu Ming opened his mouth without changing his expression.

But the waveform on the polygraph still hasn't returned to normal.

"You're still lying."

The policeman tapped the table lightly with the tip of his pen.

Remind Lu Ming.

"Okay! I also ate an extra cake and an egg."

Lu Ming raised his eyebrows, and spoke helplessly.

Speaking of which, the waveform graph on the polygraph did not show any abnormalities.

"Where did you and Zhou Hang go after breakfast?"

The policeman continued to question with a calm expression.

While speaking, he looked at the notebook in his hand and started to record again.

"Leaving the hotel and going to the street."

Lu Ming spoke calmly.

When talking, he looked calmly at the opposite glass.

His expression was refreshed, as if he was completely empty.

"What are you going to do in the street?"

The policeman sped up his speech and pressed forward with every step.

"Prepare to break out!"

Lu Ming hesitated for a second before speaking calmly.

"Is Zhou Hang with you during this period?"

The police officer was thoughtful, and the pen in his hand did not stop recording for a moment.

"No."

Lu Ming resolutely broke his mouth.

"Then where did he go?"

The policeman asked for the last time, and subconsciously held his breath.

He stared intently at the waveform graph on the lie detector monitor.

The voice fell.

Like a stone sinking into the sea.

The entire interrogation room became extremely quiet in an instant.

After a brief silence.

Only then did Lu Ming slowly reply, "I don't know!"

The police officer frowned upon hearing this.

After seeing that the waveform diagram on the polygraph did not appear any abnormality.

He sighed helplessly.

Then he asked Lu Ming some questions in the same way.

Basically, the information you want to know is interspersed with simple questions.

however.

Lu Ming was able to answer very calmly.

The last question is over.

The pen that the police officer had been holding tightly in his hand finally dropped.

He got up and walked to Lu Ming.

He stared at Lu Ming for two seconds, then turned and left the interrogation room.

Come to the observation room where the commander-in-chief is located.

"Team! When Lu Ming said this, there were no abnormalities in any physiological indicators."

The police officer frowned and watched the commander-in-chief report.

While speaking, he handed the notebook in his hand to the commander-in-chief.

"For people with strong psychological quality and training, this lie detector does not seem to be very easy to use."

"No wonder it has been kept in the warehouse, and it has turned gray!"

"Do you think what he said is true or false?"

The commander-in-chief stared at Lu Ming in the interrogation room.

Muttered.

After speaking, he turned around and asked the police officer for his opinion during the interrogation just now.

heard.

The policeman followed the commander-in-chief's gaze and looked inside.

Looking at Lu Ming's calm face.

Eyebrows drooping, seemingly thoughtful.

After thinking about it, he answered the commander in chief.

"Judging from my many years of interrogation experience, he doesn't seem to be lying!"

"Of course, given his training in this area, it cannot be ruled out that he is deliberately misleading us."

The policeman spoke uncertainly.

He has always been very confident.

After the confrontation with Lu Ming just now, his self-confidence was hit hard.

Now I'm not sure whether Lu Ming lied or not.

Over the years, Lu Ming is also the most difficult person he has ever met.

compare to.

Those so-called psychopaths seemed perfectly normal.
