Chapter 76 Micro-Expressions

Interrogation is a very skillful job.

To pry out what the interrogator wants from the suspect's firm mouth, he often needs not only an irrefutable chain of evidence, but also a consciousness that can cut through the psychological defense weakness like a blade, and can use the means of breaking the bottom line to play the game when necessary.

It's a pity.

Lin En didn't have a complete chain of evidence, and the extraordinary people who assisted in the investigation were not prisoners.

Otherwise, Lin En thought that if they were all locked up in a small dark room, and given a piece of bread and a glass of cold water every day, it would take less than three days of huge mental pressure to make them confess how many mistresses they had and what shameful things they had done.

No torture... No, these members of the Medical Association with noble social status cannot be treated as prisoners, which means that they can't be hard.

Then let's use soft methods.

Lin En also likes soft methods.

After finishing the work on the clerical side, he started to look for a suitable empty room in the [Light Bearer] branch without stopping. Ye Funi ran up and down with him, wondering what the standard of the young gentleman's room selection was.

Spacious? No. Good lighting? No. No light? Even worse!

Ye Funi's curiosity overcame her impatience. She wanted to see what Lin En was doing and what he could come up with. In the end, Lin En chose a very small office and started to change the layout inside.

All the extra tables and chairs were cleared out, and there were only three chairs and one table in the office. He placed the table slightly closer to the corner, so that if someone sat behind the table, they would fall into a psychological environment similar to having nowhere to escape. Looking back was the wall, and looking forward was the two interrogators.

This was a trick used by the Lighthouse Country during interrogation.

To deal with ordinary thieves, the two policemen would force the criminals into a corner and take turns firing and yelling. The criminals would either see the cold wall or the police. Under this pressure, the criminals would often quickly break down and confess.

Then there was light.

In this era, there was no such convenient thing as a desk lamp. Fortunately, Lin En used natural sunlight according to local conditions. The light was projected from the window in the direction of the interrogator. In addition to covering the facial expression, it could also exert great psychological pressure on the other party.

People often have a sense of awe engraved in their genes for the majestic existence with their backs to the sun. That is the natural worship and fear of the sacredness of human beings.

In fact, in many religious murals, the gods appear with their backs to the light, which makes them look like they are spreading glory.

"Is this useful?"

Without the airs of a boss, Ye Funi helped Lin En to coordinate the arrangement and asked with some doubts. In her opinion, after so much trouble for so long, there seemed to be no obvious changes.

"Try sitting here."

Lin En pointed to the seat he arranged for the interrogator. This was his best transformation. After all, there was no interrogation room in this era, and naturally there was no knowledge of how to arrange the interrogation room.

Ye Funi walked over with her long legs, and her boots made a thumping sound on the ground.

As soon as she sat down, Lin En came to the table, leaned forward slightly with his upper body, showing oppressive body language, and his eyes were not like a shy boy but a hawk. Ye Funi was a little frightened by Lin En's aggressive behavior, and subconsciously avoided the aggressive gaze.

Even in various dangerous and treacherous situations, her heart was not shaken, but at this moment, it was hit hard by Lin En, and Ye Funi suddenly had a strange feeling of wanting to escape.

"How does it feel?"

Lin En keenly caught Ye Funi's evasive eyes.

"It is indeed very effective." Ye Funi hesitated a little, but still admitted that after she sat down, Lin En's movements and eyes made her feel very strange.

There was panic, and some other things.

She didn't know if it was because of her, but the heroic female knight couldn't tell Lin En this.

Seeing that her arrangement was indeed effective, Lin En, who had been busy for half a day, finally breathed a sigh of relief. Clapping his hands, Lin En's smile was very bright, and Ye Funi, who was still sitting there, was reflected in his green eyes. It seemed that at a certain moment, a tiny red flashed through his pupils.

"Next, the layout remains the same, and we'll just wait for the guests to take their seats."

…………

…………

Members of the Medical Association took turns entering the room, with Ye Funi and Bill speaking and asking questions alternately.

The questions they asked were also very layered.

At first, they just chatted and asked some irrelevant questions. For example, what was yesterday's dinner and how it tasted. These questions were like relaxing chats, and the people being questioned didn't need to hide anything, and they all told the truth. Then, the level of the questioning would change, and the topic would be directed to the incident, asking them how they felt about the scene and whether the deceased deserved it.

And Lin En was as inconspicuous as a little transparent person, standing in the corner of the room and taking notes from a third-party perspective.

This questioning was also the questioning suggestion he gave.

The initial questioning was to establish the expression baseline. Lin En had to know the baseline for each of them when they told the truth, and to test their psychological defenses.

Then it was the main show.

With the super memory to freeze the expression baseline, when these people were asked about the different reactions related to the incident, Lin En was like a high-precision camera, capturing them all clearly in his brain.

From these people's faces, Lin En captured a wide variety of emotions.

Joy, boredom, anger, fear, confusion, contempt, disdain...

These emotions often do not appear alone, but appear in combination on the face, and the degree of emotion is different.

There are 44 muscles on the human face, each of which is responsible for a function. When two or more muscles move at the same time, an expression is born. The human face can convey nearly 10,000 kinds of expressions. Under the appropriate stimulus, it can be judged whether a person is lying by interpreting micro-expressions.

Although Lin En knew this theory before crossing, he was limited by the hardware and could not keep up. Even if he had some training, it was useless.

But now it is different.

Super memory gave Lin En a grand memory palace, where he can read any memory picture at any time. This also means that Lin En is turning himself into a human lie detector.

When the last person left the room, Bill and Ye Funi couldn't help but breathe a sigh of relief.

They were very tormented. According to this unique way of questioning, the two of them were actually very vague about the effect of their questioning. If it was an experienced criminal investigator from Elba Field who came to question them, they might be able to grasp something vaguely, but most of the time, the two people who were really fighting with real knives and guns really couldn't keep up.

The only one who knew the effect was actually the most inconspicuous clerk in the room.

Lin En closed his eyes uncomfortably. He analyzed and recorded too many pictures in one breath, and his brain was directly overloaded and heated.

"Give me twenty minutes, I'll go and sort it out for a while."

"Go, let's send them out first." Bill came over and patted Lin En on the shoulder.

[Suppression Bureau] It is impossible to detain so many extraordinary people just on suspicion. Besides, there was an agreement before. If they really want to arrest them, they will have to wait until the peace conference is over in two days.
