Who would study psychology if they didn't have some kind of problem?

Chapter 254 What?! [Micro-expression analysis] lie detector demonstration?! I just want to dissect you!

As Nan Zhuren spoke, he waved to Huang Xin.

Huang Xin very cooperatively tossed up a mobile phone and a stand.

Nan Zhuren then placed the phone stand in front of Lin Lilin and simultaneously turned on the camera, pointing it at the middle-aged professor in front of him.

At this point, Huang Xin had already completed the screen link between the mobile phone and the laptop through operation.

—And so, Lin Lilin's deeply lined face appeared on the big screen in front of everyone.

"Next, when I ask questions, I will use this phone to record the teacher's face."

Nan Zhuren explained the rules to the audience like a magician demonstrating a new trick.

"This phone's frame-by-frame slow-motion function in 'normal mode' has 30 frames per second, which means that in slow motion, it can capture changes on a face at the level of 1/30th of a second. This level of change is enough to clearly observe micro-expressions."

Nan Zhuren's commentary was directed at the audience, but at the same time, it was also directed at Lin Lilin.

He looked directly into the other person's eyes, watching as the other person's confusion turned into unease.

"I will make a judgment after asking the questions, to determine whether my teacher is telling the 'truth' or 'lying'."

"After I make my judgment, I will slow down the video of my teacher's expression and present the 'evidence' to everyone. Then everyone will be able to know whether my judgment is correct."

Nan Zhuren paused.

The word "evidence" startled Lin Lilin once again.

His emotional state is really very unstable right now.

Nan Zhuren turned around: "Generally speaking, micro-expression analysis requires establishing a baseline first, because everyone's micro-expression state may be different. But I am already very familiar with my teacher, so I can skip this step directly."

"But I thought I'd still like to show it to everyone."

He smiled and said, "Many of you have probably seen my videos that are widely circulated online by now, right?"

He was referring to the lie detector game designed for Wang An.

A series of kind smiles appeared below.

Lin Lilin became increasingly uneasy.

“Let’s recreate it a little bit—but with a small change.”

When facing Wang An, Wang An was being put on a pedestal, so he was very cooperative.

However, he is very wary of Lin Lilin now and is more inclined to try to get away with it.

Nan Zhuren needs to take more control of the situation.

Then Nan Zhuren suddenly turned around, pulled out a coin, and stuffed it into Lin Lilin's left hand.

Then, while pressing the [Record] button, he quickly asked, "Teacher, you have a coin in your left hand, right?"

Lin Lilin blinked.

You just put a coin in my left hand, and now you're asking if I have any coins in my left hand?

He has not yet understood Nan Zhuren's intentions.

Just as I was about to open my mouth and give that obvious answer.

But Nan Zhuren immediately interrupted him: "Very good, your current reaction is exactly the state of preparing to tell me the 'truth'."

Nan Zhuren then ignored Lin Lilin and quickly pressed the [Recording] stop button, then started playback, slowly dragging the progress bar.

On the big screen, a series of Lin Lilin's paused expressions flashed rapidly, like a stop-motion animation.

"As you can see, my actions just now elicited a very obvious expression from my teacher."

Nan Zhuren laughed and said, "It is [doubt]. Obviously, he, like everyone else, is puzzled by my behavior just now."

The audience let out a good-natured laugh.

However, once again.

Nan Zhuren made the transition very quickly, and even before everyone's laughter had stopped, he suddenly turned around again.

After repeating the act of recording, he quickly asked, "Teacher, do you have a coin in your left hand? This time, lie to me, lie to me, lie to me..."

"lie!"

The middle-aged professor was startled.

Nan Zhuren's quick response left Lin Lilin with no time to react. He didn't even have time to think about Nan Zhuren's inexplicable behavior earlier.

For a moment, the only thought that remained in his mind was "lying".

"No……"

He lied.

After uttering those words, Lin Lilin's pupils suddenly dilated.

He understood. Meanwhile, Nan Zhuren had already slowed down the video again, then pulled back—

"Everyone, I would like to apologize to you all first."

……

Nan Zhuren suddenly turned around and gave an embarrassed smile.

This statement was quite inexplicable, leaving everyone looking puzzled.

“Actually, what I want to demonstrate is not just lie detection technology,” Nan Zhuren explained. “I can even predict whether a person is about to lie before they even speak.”

Look—

The images, frame by frame, were played back in slow motion on the screen.

This time, however, a completely different expression appeared.

"The masseter muscle protrudes slightly because of clenching the teeth; the fine lines around the corners of the mouth change because of pursing the lips."

“I can tell if my teacher is about to lie just by seeing those kinds of expressions on his face—and now you can too.”

“Next, I will ask the teacher some everyday questions. We'll record it again, and play it back, so everyone can judge with me whether my teacher is lying or about to lie. If the teacher feels offended, they don't have to answer.” Nan Zhuren made a troubled expression. “But—”

What kind of questions would make someone reluctant to answer and subconsciously lie?

Lin Lilin stood up abruptly.

He understood—

Lie detector demonstrations and micro-expression analysis are all fake!
If Nan Zhuren's previous case sharing and analysis still had a genuine academic spirit—that was to use his own failures to help his colleagues prevent crises—then...

At this moment, Nan Zhuren had broken free of that state and had only one goal in mind—

He wanted to expose every piece of Lin Lilin's skin, every piece of flesh, every tendon, and every bone on the stage, in front of everyone!

Not a single thing left!
……

Lin Lilin's large movement caused his face to leave the camera's view.

However, Huang Xin had already rushed up in three steps, picked up his phone, and shoved it hard into Lin Lilin's face!
"Teacher, the case I just showed you is the one you gave me, the one that ended up jumping off a building. You gave me this case yourself, right?"

Lin Lilin took a step back in alarm.

no answer.

Nan Zhuren had already instructed Huang Xin: "Stop recording, play back!"

Huang Xin reacted extremely quickly, his movements displaying the proficiency of countless rehearsals. A series of jerky expressions flashed rapidly across the large screen, like a stop-motion animation, before finally settling on one frame.

[Clenching teeth], [Pressing lips]

"Is the visitor the one you assigned to me? Such a simple question, teacher, why would you even think of lying!" Nan Zhuren shouted.

Lin Lilin turned to leave.

The next second, Nan Zhuren grabbed his collar.

"Lin Lilin, when you were intervening with the client, you deliberately abused medication, didn't you?!"

"I..." The middle-aged professor, his body restrained, tried to argue.

He then realized that this was not right.

But that's enough time.

"Stop, rewind!"

A series of paused expressions flashed by again, stopping at [gritting teeth] and [pursing lips].

There was a moment of silence in the room.

Then, an uproar ensued!
Nan Zhuren, however, has not stopped.

"Why is drug abuse driven by the desire to make money, right?!"

"—Stop, rewind!"

The screen paused on an emoji again.

It was still the same old routine: gritting her teeth and pursing her lips.

“Not just my client, but other clients I don’t know about, you’ve had many instances of substance abuse, haven’t you!”

[Clenching teeth], [Pressing lips]

"The reason your current mental health clinic's accounts are fine is because you have separate private ledgers, right?"

Nothing unexpected.

The same words of clenched teeth and pursed lips appeared on the screen and were seen by everyone.
