A young boy from the 1970s, separated from his family, fled famine and led his younger brother into

"Knock knock knock—"

The next morning, the door of the Lu family was knocked on precisely on time.

Zhou Yayun's palms were sweating with nervousness as she ran to open the door.

Standing outside the door were the same two staff members from the Municipal Education Bureau from yesterday.

The older man, surnamed Wang, had a serious expression, and his eyes behind his glasses held a scrutinizing gaze.

The younger one, surnamed Li, had an undisguised look of disdain and impatience in his eyes.

Clearly, in their view, this was nothing more than a farce orchestrated by a self-proclaimed patriarch.

"Political Commissar Lu, Sister Zhou, we're here for a routine inquiry," Officer Wang said, adjusting his glasses in a businesslike manner.

"Oh, alright, please come in, please come in."

Zhou Yayun quickly ushered the person in.

In the living room, Lu Zhenguo had already brewed tea, but the atmosphere remained tense, like a taut string.

Lu Nianci sat quietly on the sofa, her small face revealing no emotion.

"Ahem," Officer Wang cleared his throat, took out a notebook and pen from his briefcase, and assumed an interrogation posture.

"Lu Nianci, is that right? We received a report that you engaged in some... well, irregularities during your grade-skipping exam. We also received feedback regarding your personal conduct..."

Before he could finish speaking, a cold voice suddenly came from the side.

"Officer Wang, right?"

Lu Xingzhou came out of the room at some point.

He was dressed in simple training clothes, his figure was as upright as a pine tree, and he exuded a cold aura that kept strangers at bay.

He was also carrying a heavy military canvas bag.

With a "bang," he threw the canvas bag onto the coffee table, making a dull thud.

The two education bureau officials were startled and turned to look at him.

"You can't tell how good my sister is just by asking her."

Lu Xingzhou unzipped the canvas bag and took out stacks of brand-new exam papers, still smelling of fresh ink.

"This is the latest version of the national unified mock exam paper, specially prepared for the children of officers in our military region who are preparing for the college entrance examination. The difficulty level is only higher than the actual college entrance examination."

He arranged the thick stack of exam papers on the coffee table, categorizing them by subject.

Chinese, Mathematics, Politics, Physics, Chemistry...

Each subject is like a mountain, pressing down on you until you can't breathe.

"Since you two are here to investigate, that's perfect, you can also be our witnesses."

Lu Xingzhou glanced at the clock on the wall.

"It's exactly 9:00 AM now. Let's follow the schedule for the college entrance examination."

"You will all be here, watching my sister finish these papers."

"Whether she's a true genius or just a charlatan, we'll find out soon enough."

This...this is going to be an on-the-spot exam?!

Both Officer Wang and Officer Li were dumbfounded!

They're here to ask questions, not to proctor the exam!

"This...this is against the rules, isn't it?" the young officer Li retorted instinctively.

"Regulations?" Lu Xingzhou sneered. "My sister, a five or six-year-old child, is taking the college entrance examination. This is not within your 'regulations'."

"Today, either you stay here and watch her take the exam."

"Or, I can call Mr. Gu in Beijing right now and have him personally discuss the 'regulations' with your leaders."

Grandpa Gu… Grandpa Gu?!

When Officer Wang and Officer Li heard this name, their faces turned pale instantly!

That's a top-tier figure whose every stomp of his foot could make the entire capital tremble!

They wouldn't dare to provoke them!

"Test! Test! We...we'll just watch from here!" Officer Wang hurriedly wiped the cold sweat from his forehead, his attitude instantly making a 180-degree turn.

Thus began what can be described as the most bizarre "investigation" in history.

The Lu family's living room was temporarily converted into an examination room.

Two education bureau officials became temporary proctors.

Lu Zhenguo and Zhou Yayun sat nervously in the distance, not daring to even breathe.

Lu Xingzhou, on the other hand, acted like an iron-faced examiner, personally sharpening his sister's pencil and laying out her draft paper.

The exam has officially begun.

At first, Officer Wang and Officer Li were just waiting to see what would happen.

It's already quite good that a five- or six-year-old toddler can understand the questions.

However, when they saw Lu Nianci pick up her pen and, as if she hadn't even looked at the questions, quickly write down the answers on the test paper, their expressions began to change.

Especially the math exam.

Functions, analytic geometry, sequences... those things that can make even adults rack their brains...

In Lu Nianci's writing, it seems to become as simple as "1+1"!

She rarely even used scratch paper; her mental calculation speed was faster than their reading speed!

Two hours later, the math paper was handed in.

Unconvinced, Officer Li picked up a red pen and began grading the answers.

Ten minutes later.

The red pen in his hand fell to the ground with a "thud".

Full score!

One hundred percent!

Not a single question was answered correctly, not a single step was omitted, and even the solution method was simpler and more efficient than the standard answer!

"Gulp."

Officer Li swallowed hard, feeling as if his worldview was being pressed to the ground and repeatedly rubbed against it.

Next are physics and chemistry.

Lu Nianci's speed was still outrageously fast.

She wrote those complex problems involving mechanics, electricity, and molecular formulas with ease and without the slightest pause.

Officer Wang and Officer Li were completely numb.

Looking at that tiny figure, they felt as if they were seeing not a child, but... a supercomputer in human skin!

Four hours later.

When Lu Nianci put down her pen after finishing the last chemistry exam, the two officers looked ashen-faced, their eyes filled with awe and fear as they stared at her.

Lu Xingzhou, expressionless, gathered all the graded papers together and handed them to them.

"Officers, now, do you think my sister's academic level is sufficient to take the college entrance examination?"

Is it enough?

That's more than enough!

With this level of skill, she'd be more than qualified to be a university professor!

Officer Wang stood up shakily, looked at Lu Nianci, and stammered, "Enough...enough! Lu Nianci...no! Su Nianci! It's...we were blind to your worth! We were wrong!"

However, just when they thought this horrific "torture" was finally about to end.

Lu Nianci suddenly pointed to the final question on the physics test she had just finished, about the motion of a small ball, tilted her head, and spoke with an "innocent" look.

"Uncle Wang, Uncle Li."

"I think this question wasn't very well designed."

The two of them felt a sudden jolt.

"Its problem setting ignores the nonlinear changes in air resistance at different speeds, and the initial conditions it provides are almost impossible to achieve in real-world physical models."

"In fact, if we use the Lagrange equations to build a motion model and then introduce perturbation theory for correction, the solution to this problem will be more elegant and closer to the truth."

The little girl's voice was childish and sweet, but the words she spoke were like thunderbolts, striking the two of them hard on the top of their heads!

Lagrange's equations?

Micro-perturbation theory?

What the hell is this?!

Isn't this the kind of knowledge you only encounter in university physics departments, or even graduate programs?!

Young Li, who prided himself on being one of the first college students after the resumption of the college entrance examination, felt his face burning with shame!

His pride in his knowledge seemed like a joke in front of this five- or six-year-old child!

The so-called "investigation" has now completely devolved into a one-sided, "lower-dimensional attack".
