Who would study psychology unless they had some issues?!

Chapter 255: Chapter 253: What Exactly Is This Principle?

Seeing that his emotions seemed inconsistent with those around him.

Director Xia maintained his composure and quietly pulled his daughter over.

"Tiantian, what did Mr. Nan just do... Tiantian? Tiantian!"

"Ah... ah?"

The young girl looked as if she had just woken from a dream, reluctantly pulling her gaze away from Nan Zhubin, "What’s wrong, Dad?"

Director Xia took a deep breath.

He forced his inner feelings to remain calm, merely pointing in the direction of Nan Zhubin and asking, "What did Mr. Nan just do? Why does everyone have that expression?"

Upon hearing the question.

The young girl’s eyes immediately brightened, "Ah, just now, after Doctor Chen woke Professor Lin, Mr. Nan asked where the ledger and the USB drive were. Then, although Professor Lin didn’t say anything, Mr. Nan suddenly asked if the USB drive was in the briefcase, and Professor Lin immediately panicked when he heard that."

Director Xia remained composed on the surface, yet internally he nodded, starting to analyze the principle—

—In theory, a USB drive can be carried personally. But earlier, after Director Xia subdued Lin Lulin, he casually searched him and found nothing but a phone and a box of painkillers.

So this "USB drive that could possibly be carried personally" must be in the briefcase.

Using reasonable speculation to bluff the suspect, then confirming one’s hypothesis through their reaction. That kind of tactic exists in criminal investigation, and most experienced detectives can achieve it.

[At most, it can be said that Mr. Nan guessed quite accurately...]

"Then Mr. Nan instructed that Senior Brother Huang to look, and indeed found it in the briefcase!"

As Xia Tian recounted the following events, she felt herself getting excited: "But then, Senior Brother Huang said the USB drive was password-protected. Mr. Nan immediately asked Professor Lin for the password; he asked several times, and even though Professor Lin didn’t speak, Mr. Nan quickly inferred the password was 8 digits, without letters or characters, and after asking a few more questions, determined it was a birthday."

"Yet Mr. Nan seemed unaware of Professor Lin’s birthday, so he confirmed one digit at a time... Though it’s not clear how he did it, it’s truly impressive!"

...

Director Xia always believed his daughter choosing to study law was a fitting choice because her language skills had always been strong since childhood, with clear articulation and logical coherence.

But now, for the first time, Director Xia felt his daughter seemed somewhat incoherent.

He was listening in a fog.

What on earth is all this? Asking and answering a few questions then deducing a password?

What principle is this?

Could it be that his daughter’s recounting is flawed?

No, likely not.

Then it must be Mr. Nan’s method that is problematic!

Peculiar tactics, and the answers derived might not necessarily be correct...

Not far off, Huang Xin quickly retrieved the USB drive from Lin Lulin’s briefcase upon Nan Zhubin obtaining the first answer, and at this moment followed Nan Zhubin’s answer, inputting Lin Lulin’s birthday.

"It’s unlocked!" Huang Xin appeared more excited than upon graduation, "This is the USB drive!"

Since he was overly eager and excited, Huang Xin unwittingly allowed the contents of the USB drive to project onto the big screen through the computer; realizing it may involve visitor privacy, he immediately cut the data connection.

But the brief moments were enough for those present to glimpse fragments of the USB’s contents. They immediately understood what Lin Lulin had been doing previously through the neatly arranged folders and files.

And what Nan Zhubin had just accomplished.

Those who had shared Director Xia’s doubts of "was he just guessing" were now silent.

Moreover, their gaze towards Nan Zhubin grew increasingly puzzled, and admiration increased. Like undeveloped monkeys watching their kin use stones to crack open coconuts and then create a raft from coconut shells to set sail.

—Impossible to understand, utterly incomprehensible!

Of course, not all monkeys were undeveloped.

Among the monkeys, there were a few who were adept thinkers, having previously made such conjectures as "stones can crack open coconuts" and "combined buoyancy of multiple coconut shells can support monkeys on water." These old monkeys now looked at Nan Zhubin with a gaze filled with appreciation.

And.

Possessiveness...

...

Under the watchful eyes of these old monkeys, Nan Zhubin continued questioning Lin Lulin.

"Alright, we only have the ledger left. But since the USB drive has been found, ’Teacher’, are you still trying to resist?"

Nan Zhubin reverted to the respectful term yet this time, a touch of mockery was present.

"At this moment, voluntarily confessing uncollected evidence might even lead to a lighter sentence, right, Director Xia... Director Xia?"

Director Xia had somehow sidled over to Huang Xin.

He seized the mouse from Huang Xin’s hand, quickly browsing through the contents of the USB drive, glancing at the screen, then at Huang Xin, at the screen again, before turning back to look at Nan Zhubin.

Nan Zhubin blinked, deliberated inwardly, and strode forward.

"Director Xia, can the contents of this USB drive be used as evidence?"

Director Xia tore his gaze away from the computer.

His face remained stoic.

He answered, "Yes."

"But..." he paused, probing, "You mentioned earlier that he also has a ledger, right? Can you..."

"I can." Before Nan Zhubin’s words fell, he had already turned to Lin Lulin, "Teacher, where is your ledger kept?"

He began organizing his logic autonomously.

"Ledgers are inconvenient to carry personally, so even if not on hand, you must place them somewhere you visit daily or at least two to three times a day to feel secure, correct?"

"Correct—very good, then I’ll guess in that direction."

Indeed, a peculiar form of self-questioning and answering... Director Xia narrowed his eyes, attempting to ascertain Nan Zhubin’s method.

"At home—the wrong place."

"At the clinic—the wrong place too."

"Surely not in the office again—it’s actually in the office?"

Nan Zhubin’s tone rose, "You actually returned it to its original place? Because you’re discharged and feel the office is safe? You at least changed the password—yes, indeed changed it."

Director Xia pursed his lips.

This time saw it happen, yet... didn’t comprehend.

Sure enough, it seemed slightly theatrical.

Because it’s overly simple, not even seeming credible.

But...

Director Xia turned back to glance at the laptop and the USB drive already removed from his hand.
