The villainous young lady is actually a scientific research genius!

The office of the mathematics teaching and research group was filled with smoke.

Yan Zheng sat at his desk, a stack of test papers piled up in front of him, his face even more grim than the overcast sky outside the window.

After grading the last paper from Class A, Zhang Yan sighed, "Old Yan, the highest score in Class A is 94, and it's still Lu An'an's."

"94?" Yan Zheng snorted coldly, stubbing out his cigarette in the ashtray. "These kids always brag like crazy, but when it comes to real difficulty, they show their true colors."

"The questions you set this time were definitely too difficult." Another older teacher took off his glasses and rubbed his temples. "The passing rate is probably less than 30%."

"Difficult?" Yan Zheng narrowed his eyes. "The problems in the National Mathematical Olympiad will only get harder. If we don't identify truly talented individuals now, will we embarrass ourselves on the competition stage?"

Silence fell over the office.

Zhang Yan flipped through the grade registration sheet in his hand, then suddenly remembered something: "By the way, have the papers for Class B2 been graded yet?"

The teacher in charge of grading Class B's exam papers was a young woman. She was engrossed in writing among a pile of papers, saying without looking up, "Almost done, almost done, just a few more pages left..."

Before she could finish speaking, she suddenly stopped writing and froze on the spot.

"What's wrong?" Zhang Yan asked.

The female teacher did not answer, but looked at the test paper in her hand, her breathing becoming rapid.

"Xiao Li?" Zhang Yan walked over. "What happened?"

The female teacher looked up, her eyes wide: "Teacher Zhang...you...you look at this test paper..."

Zhang Yan took the test paper, glanced at it, and was also stunned.

Yan Zheng noticed something was wrong, got up and walked over: "What test paper?"

Zhang Yan didn't say anything, and simply handed him the test paper.

Yan Zheng took it, and the moment his gaze fell on the paper, he felt as if he had been struck by lightning.

The handwriting is neat and legible, with no alterations whatsoever.

All multiple-choice and fill-in-the-blank questions were answered correctly.

The steps for solving the problem are concise and clear, with each step precisely hitting the scoring points.

The last two challenging questions—

That analytical geometry problem, the conventional solution requires solving simultaneous equations, Vieta's formulas, and discussing parameters, which would fill at least a whole page.

But this exam paper only has a few lines.

The answer can be obtained directly using polar coordinate transformation in three steps.

Yan Zheng's hands began to tremble.

He turned to the last, most challenging problem: derivatives.

He set this problem extremely challenging, involving case-by-case analysis, zero-point problems, and inequality proofs. It was adapted from a real question from last year's national league competition.

He wrote two whole pages of the standard answer himself.

But on this exam paper—

Only half a page.

He used a substitution method he had never seen before, skipping all the tedious discussion steps and proving it in no time.

Yan Zheng stared at the solution, his brain working at lightning speed.

This method...yes...is correct...even more ingenious than the standard answer...

He abruptly flipped to the beginning of the exam paper, his gaze fixed on the name column.

Lu Zhaozhao.

"It's her..." Yan Zheng murmured to himself, "It really is her..."

"Who?" The other teachers gathered around.

"Lu Zhaozhao!" Yan Zheng slammed his hand on the table. "That student Zhang Yan told me about!"

Zhang Yan also came over to look at the exam paper, and the more he looked, the more alarmed he became: "This...this solution...Old Yan, she used a university-level mathematics method, didn't she?"

"Not just universities." Yan Zheng pushed up his glasses. "Even students from the mathematics department of Beijing University wouldn't often come up with an idea to use this polar coordinate transformation in this problem."

The office was completely silent.

Everyone stared at the exam paper.

"How many points?" someone asked.

The female teacher swallowed hard: "Full...full marks. 120 points, not a single point lost."

Gasps of astonishment filled the air.

"Perfect score?"

"How could someone get a perfect score on a test this difficult?"

"Still a student in Class B2?"

……

Physics Teaching and Research Group Office.

Team leader Zhou Mingyuan was staring blankly at a test print.

"Teacher Zhou, what's wrong?" A young teacher next to her came over.

Zhou Mingyuan pointed to a question on the exam paper: "Look at this solution to this challenging question about electromagnetic induction..."

The young teacher glanced at it and was stunned: "This...this uses the differential form of Lenz's law?"

"That's right." Zhou Mingyuan pushed up his glasses. "This content isn't in high school physics textbooks at all; it's something from university electrodynamics."

He flipped to the last comprehensive mechanics problem.

The standard solution requires analyzing the forces and motion processes of multiple objects and listing a complex set of equations.

But on this exam paper, the answer was calculated in just a few steps using the conservation of energy and the conservation of momentum.

Simple, efficient, and perfect.

Zhou Mingyuan looked at the name at the beginning of the book—Lu Zhaozhao.

"Lu Zhaozhao?" he murmured to himself.

"Teacher Zhou, what was the score?"

"Full marks." Zhou Mingyuan put down the test paper. "Not a single point was deducted."

The office fell silent instantly.

……

Chemistry Teaching and Research Group Office.

Lin Fang, the head of the teaching and research group, held a test paper in her hand, her brows furrowed.

"Teacher Lin, what's wrong?" asked the teacher next to her.

Lin Fang didn't say anything, she just handed over the test paper.

The teacher took a look and exclaimed in surprise, "This...this organic synthesis problem's route design...she actually used retrosynthetic analysis?"

"Not only that." Lin Fang pointed to another question on the test paper, "For this balancing question, she used a combination of the oxidation number method and the ion-electron method, which was even faster than the standard answer."

She paused, then continued, "And this experimental question—she not only answered all the steps correctly, but also pointed out three potential problems with the experimental design in the notes, and gave suggestions for improvement."

Everyone in the office gathered around.

"This...this is something a high school student could write?"

"I've taught chemistry for twenty years and I've never seen a student of this caliber."

Lin Fang took a deep breath: "Perfect score. Perfect score in chemistry."

"Is it Lu Zhaozhao again?"

It is clear that the person asking the questions had already received information from the math and physics grading teams.

Lin Fang nodded.

The office was completely silent.

After a long pause, someone whispered, "I heard... she always hands in her paper early..."

……

Office of the Chinese Language Teaching and Research Group.

Wang Hui, the head of the Chinese language group, is grading essays.

When she saw Lu Zhaozhao's argumentative essay, the red pen in her hand paused.

The arguments are clear, the reasoning is rigorous, and the use of classical references does not feel like a piling up of words; every word is precious yet lively.

What's even more remarkable is that the entire article has a tight logical chain, with not a single superfluous word.

After reading the last word, Wang Hui remained silent for a long time.

"This essay..." she murmured to herself, "If it were submitted for the college entrance examination, it would definitely be a perfect score essay."

She wrote a number in the score column: 49.

The total score for Chinese was 50, and the composition score was 49. Considering that the composition could not be given full marks, this was the highest score she could give.

"Lu Zhaozhao..." Wang Hui looked at the name thoughtfully.

……

English Teaching and Research Group Office.

English group leader Zhao Min held a test paper with all the cloze test and reading comprehension questions answered correctly.

She turned to the essay section, and her brows gradually relaxed.

The vocabulary, sentence structure, and grammar of this essay have reached the level of College English Test Band 6.

More importantly, the article's logic and fluency are unlike anything a high school student could write.

Zhao Min wrote 120 points in the score column.

"Perfect score..." she whispered, "Perfect score in English."

Similar scenes were playing out in the marking rooms for other subjects, such as biology, history, geography, and politics.

Every research group leader who saw Lu Zhaozhao's test paper went through a process of surprise and shock, and finally wrote the same result in the score column - full marks.

……

In the mathematics teaching and research group office.

Yan Zheng picked up the test paper and turned to walk out.

"Old Yan, where are you going?"

"Find the principal!" Yan Zheng said without turning his head. "This kind of student needs special treatment!"

He had just reached the door when his phone rang.

It was Zhou Mingyuan, the physics group leader, who called.

"Old Yan, isn't Lu Zhaozhao from Class B2, which Zhang Yan is in charge of?"

Yan Zheng was taken aback: "Yes, what's wrong?"

"She also got a perfect score in physics." Zhou Mingyuan's voice was filled with undisguised excitement. "And the ingenuity of her solution is something I've never seen in my twenty years of teaching."

Just after I hung up the phone, Lin Fang, the head of the chemistry group, called back.

"Teacher Yan, Lu Zhaozhao's chemistry..."

"I know," Yan Zheng took a deep breath, "it's a perfect score, right?"

How did you know?

Yan Zheng did not answer, but simply hung up the phone and strode towards the principal's office.

His heart was beating very fast.

This was the first time he had ever encountered a genius student who excelled in all subjects.

……

at the same time.

In the classroom of Class B2.

Shen Qingqing lay slumped on the table, looking completely listless.

"Oh no, I'm definitely failing math..." she muttered to herself. "I didn't even finish half of those questions... The same goes for physics and chemistry, I guessed on so many of them..."

Lu Zhaozhao sat next to her, writing and drawing in her notebook.

Shen Qingqing glanced at it secretly and saw the dense chemical equations and structural formulas, which made her head spin even more.

"Zhaozhao, aren't you worried?"

Lu Zhaozhao didn't even look up: "What are you worried about?"

"My grades!" Shen Qingqing exclaimed anxiously, "What if I fail the exam?"

Lu Zhaozhao put down her pen, looked up at her, and said, "So what if you failed the exam?"

Shen Qingqing was speechless.

Lu Zhaozhao continued writing with her head down: "A score is just a number. It can neither prove that you are smart nor that you are stupid. The only thing it can prove is your position in this evaluation system."

Shen Qingqing was stunned: "Wh...what do you mean?"

"What I mean is," Lu Zhaozhao closed her notebook, "if you care about this system, then grades matter. If you don't care, they're just a piece of waste paper."

Shen Qingqing scratched her head, feeling that she could only understand half of what Zhaozhao was saying.

"So...do you care?"

Lu Zhaozhao remained silent for a few seconds.

"What I care about has never been grades."

The sky outside the window was overcast and gray, as if it were about to rain.
