Chapter 300: Chapter 298: Target Student Arrives

"You mean, not only can you identify the opponent’s intent to lie during negotiations like before—" Chonghui was referring to the previous argument with the short man, "—but you can also accurately identify the emotions of the experiment subjects?"

Chonghui’s last sentence lifted a bit uncontrollably, realizing that he didn’t seem to have a clear understanding of his junior’s talent.

Nan Zhubin blinked his eyes: "You didn’t know?"

Chonghui also blinked. He genuinely didn’t know.

"Let me demonstrate for you..."

Nan Zhubin simply took the camera and pulled out the video file, fast-forwarding.

"Look, when this student saw the image with the theme of [exam anxiety], there was a very noticeable anxiety reaction, which aligns with our emotion induction purpose. Look at his neck, throat, and also the inner sides of his eyebrows, etc..."

The playback on the video was still at normal speed, and with Chonghui’s ability, he could barely see the major changes in the neck, throat, and such body parts, but—

"Where’s the change in the eyebrows?" Teacher Xiao Zhao, standing next to him, asked for Chonghui.

Nan Zhubin glanced at Zhao Xinyu, then at Chonghui.

He started playing frame by frame in slow motion.

Then he pressed pause, repeatedly switching between the [forward] and [backward] buttons with his left hand, while drawing a circle on the screen with his right hand: "Here, it’s this."

The video on the screen kept switching back and forth between two frames.

Actually, without Nan Zhubin specifically pointing it out, when the video slowed down to this point, Chonghui could also see it clearly enough.

However, he identified it through the device’s slow motion, but how about Nan Zhubin?

With the naked eye?

[Or did he meticulously replay it in advance, which is why he’s so familiar, and that’s why this subject took so long...]

"Let me give another example."

Then they saw Nan Zhubin directly take Chonghui’s camera and played the emotion induction record of the female student from Chonghui’s experiment.

"Let’s see... oh, senior brother, your subject has a bit more issues than mine."

Nan Zhubin said to himself: "Your subject, when seeing the image of [two desk mates listening to music with the same earphone], didn’t show [joy] or [relaxation], but instead [memory]."

"Look, the arc of her mouth, the dilation of her pupils, the direction of her gaze, and so on all changed; also, um... her ears are a bit red, her nostrils expanded due to accelerated breathing, and the blink rate also increased."

"She should be reminiscing about her boyfriend? This kid’s in an early relationship." Nan Zhubin said with conviction.

Chonghui blinked his eyes, observing Nan Zhubin speaking a bit, pausing for a while, and then speaking again, accurately identifying the micro-expression changes of the student being tested each time he paused.

To be aware that he conducted this test, but even if he replayed and reviewed it, he might not be able to spot so many things in one go...

"Hmm? What’s up with Teacher Zhao?"

At this moment, Teacher Xiao Zhao suddenly displayed an expression as if she wanted to say something but stopped, which was caught by Nan Zhubin.

"This kid wouldn’t have consulted Teacher Xiao Zhao about love-related issues, would she? Sorry, I shouldn’t inquire, just pretend I didn’t say anything."

Teacher Xiao Zhao closed her mouth, but this reaction, in fact, said everything.

Chonghui silently replayed the video segment that Nan Zhubin had just pointed out frame by frame.

After a long time, he slowly said.

"Hmm, let’s exclude this segment of data first, it’s indeed not very standard, I didn’t expect such a situation with the first subject." He controlled his tone to be as calm as possible, "And then junior if you encounter similar situations while collecting data, mark it, and we can organize it together in the evening, saving a lot of effort..."

"Okay." Nan Zhubin nodded without any objection.

"It’s okay to take it slow..." Chonghui added.

...

Watching Chonghui begin to replay the content frame by frame for the third time, Nan Zhubin shrugged, suddenly recalling something, and quietly asked Teacher Xiao Zhao:

"Teacher Xiao Zhao, has the list for selecting the students to participate in data collection been finalized?"

Upon hearing this, Teacher Xiao Zhao immediately started searching through the files: "Ah, yes, do you need to see it, Mr. Nan?"

Nan Zhubin waved his hand: "No, I just thought the previous selection might have some issues."

He organized his words: "We used [stratified sampling] to select students from different grades and performance levels for the academic test subjects, right? What about the sports students? The art students?"

"Mr. Nan, you mean..."

"I mean, for sports students and art students, their base isn’t as large as the academic test students, so [sample survey] isn’t quite as representative, it’s better to use [census]."

Teacher Xiao Zhao immediately understood Nan Zhubin’s point: "You mean to include all the sports and art students in the list, right?"

Nan Zhubin nodded with satisfaction and turned to leave.

Teacher Xiao Zhao started typing rapidly, following Nan Zhubin’s instructions to add to the list. Meanwhile, she occasionally glanced in Chonghui’s direction.

Although she wanted to accommodate Mr. Nan, she knew Mr. Zhong was the decision-maker.

And Mr. Zhong seemed to perpetually prevent Mr. Nan from doing "extra" things.

"Eh? Teacher Zhong, you are... thinking about what?"

However, Chonghui was currently not paying attention to Teacher Zhao’s movements, nor did he seem to care about what Nan Zhubin just said. He simply kept replaying his recording over and over again.

Eventually, he wasn’t even focused on the screen, but rather in a daze, his mind wandering somewhere.

"Huh? Huh... were you talking to me? Did something happen?" Chonghui snapped out of it, brought back by Teacher Xiao Zhao’s call.

Teacher Xiao Zhao blinked her eyes: "...No, I was just curious about what you were thinking so deeply about, Teacher Zhong."

Upon hearing this question, a subtle smile appeared on Chonghui’s face.

"I, ah, I was thinking about what reaction the others in the research group will have after Nan Junior returns with me to Jiangdu."

The tall Ph.D. student pursed his lips.

"And our neighboring research group’s mentors and classmates... I’m also looking forward to seeing their reactions..."

...

Once [confirming] Nan Zhubin was familiar with the process, the progress of data collection rapidly advanced.

One student after another came in and then left, with the camera recording emotional facial expression reactions one after another.

Everything went smoothly.

The only slightly less than perfect aspect was during lunch, Nan Zhubin took a nap, realizing that this form of simple dialogue didn’t count as [consultation hours] and wouldn’t help achieve the [monthly goal].

This didn’t leave him in the best mood.

However, when a tall student with a buzz cut finally appeared at the doorway following a knock,

Nan Zhubin finally showed a smile for the first time today.
