018 Sneaking Over the Threshold (Thanks to Sponsor Snoopy)

Even though it made Lin Yujing very uncomfortable, Yu Hong's praise did not stop.

"Lin Yujing, you don't need to be embarrassed. The teacher is not exaggerating at all."

"This time, we're going to talk about the monthly exam papers, and we'll also change the method."

"We'll have the student who got a perfect score, Lin Yujing, explain it to everyone."

"I hope you will listen."

"Especially those of you who study hard but do not achieve good results, see if you can get some inspiration."

As Yu Hong spoke, he stepped aside and raised his hand, inviting Lin Yujing to the stage.

Lin Yujing giving a lecture?

The class became lively.

But Lin Yujing buried her head and kept shaking it.

Jiang Qinghua saw this and took the lead in clapping: "Come on, Yujing, the teacher asked you to go up."

The classmates followed suit, clapping in a ruckus.

"Begging the learning god to teach us."

"The future professor of the chemistry department at Ji University is here!"

Even Liu Xin clapped wildly.

She looked good, who cared what she said.

Looking at Lin Yujing's shy look, Li Zheng snorted and laughed.

He knew Lin Yujing.

It was impossible.

Someone like her, impossible to share her learning methods.

Sure enough, Lin Yujing half-covered her face and raised her hand: "Teacher Yu, my throat's not feeling well..."

"Ah, is it..." Yu Hong, somewhat disappointed, returned to the podium. "Next time then."

The students were also very disappointed.

They would have to listen to the usual explanation again.

Only Jiang Qinghua's expression brightened. He lowered his head and risked taking out his phone to start operating it.

Yu Hong started explaining the problems.

Li Zheng also spread out his paper, listening to each problem one by one.

After studying continuously for more than twenty hours, this paper seemed trivial now.

Looking at his mistakes, he even blushed with shame, as if looking at an idiot.

While the teacher explained the problems, he also re-did the ones he got wrong, writing the correct answers next to them to check his learning outcomes.

For most of the wrong problems, Li Zheng could almost correct them at a glance, even at a normal learning speed, correcting all of them took only a few minutes.

He felt a kind of smoothness he had never felt before.

Not the clarity of thought in physics or math, but the fluency of language or English.

This integration was hard to describe in words.

Turns out, all that time before was building up.

Now, he barely touched the threshold of chemistry.

Even so, he still hadn't fully understood the seventh problem.

Just as Yu Hong also reached this part.

"Now, look at the seventh problem, the only problem Liu Xin guessed right, a giveaway question."

"Which of the following statements is incorrect—"

"[A. Sucrose, fructose, and maltose are all disaccharides.]"

"Right from the start, we learned that fructose is a monosaccharide, so A is incorrect. Choose A."

"Because it's a single-choice question, to save time during the exam, there was no need to look at B, C, and D."

"But here, we still have to talk about them."

"[B. Enzymes are a type of protein with catalytic properties.]

"This statement is correct, no need to say more, it's in the textbook."

"[C. Different crops have different optimal pH ranges for growth.]

"Even if you don't look at the textbook, common sense should tell you this is correct."

"[D. Industrial electroplating has certain pH requirements for the plating solution.]

"I'm afraid you might not get this giveaway question, so I specifically put this obviously correct D option."

"Some student did not disappoint."

"In summary, B, C, and D are completely correct, A is obviously wrong, so choose A."

In the laughter that followed, Liu Xin scratched his head again.

He finally got one right, and it still got targeted?

"But!" Yu Hong suddenly changed his tone and turned to Li Zheng. "We have a hard-working student in our class who gave a ridiculous answer. Li Zheng, tell us what you filled in?"

"A, B." Li Zheng answered.

"You are really something. You've been doing papers for more than a year and don't know it's a single-choice question?"

"I really don't know where all your hard work has gone with this answer."

Sparse laughter echoed.

Liu Yue craned her neck from afar, enjoying the joke.

"Teacher, Li Zheng memorized the whole book."

For a moment, discussions were everywhere.

Occasionally, some people showed a superior-intelligence look.

"Hard studying is still not working."

"Li Zheng has studied himself silly, even made multiple choices..."

"I didn't even study, and I got this question right, haha."

Being looked at by the whole class.

Li Zheng was actually okay with it.

Except, he didn't want to be seen by Lin Yujing...

He couldn't help but glance sideways, observing out of the corner of his eye.

Strangely, such a good opportunity, Lin Yujing didn't mock him.

Instead, she was nervously flipping through her book.

On the podium, Yu Hong sighed again and again.

"Hey... Did I ask you to memorize it?"

"Understand, the key is to understand."

"Li Zheng, ask Lin Yujing if she memorized it."

"You tell me, where in the chemistry book does it say enzymes are not proteins?"

"It doesn't." Li Zheng nodded. "The description on page 81 of the textbook is—'Enzymes are a special type of protein, an important catalyst in living organisms.'"

"See, although your eyesight is bad, your memory is excellent." Yu Hong raised his head and asked, "Since the book says this, why did you still choose B?"

"Because the description in the chemistry book conflicts with the description in the first-year biology book." Li Zheng explained, "The chemistry book says enzymes are a type of protein, but the biology book says most enzymes are proteins, and a few are RNA."

"For this reason, I went through great efforts to access Wikipedia."

"According to Wikipedia, the description matches the biology textbook."

"Afraid of any omissions, I opened more entries and checked repeatedly."

"Cech discovered ribozymes in 1981 and received the Nobel Prize in 1989 for this discovery."

"In addition, mainstream articles on Zhihu and Zhiwang also clearly state that enzymes can also be RNA."

"Other new editions of chemistry textbooks also use the above description."

"Based on this, it is confirmed that the description in the chemistry textbook used by our school is incorrect."

"Afterwards, I wrote an email to the education publisher."

"I hope other students won't waste time on this issue."

"Therefore, the option B, enzymes are proteins, is an incorrect description. The correct description should be 'most enzymes are proteins.'"

"In summary, I chose A and B."

After Li Zheng finished speaking.

The atmosphere in the class became eerie.

Silence.

Coldness.

And "hmm."

Lin Yujing held the textbook, her mouth slightly open as she stared at Li Zheng.

This time, she wasn't mocking.

It was actually respect.

Seeing her pious look.

Li Zheng nodded to her in goodwill.

Although we have conflicts in many areas.

When it comes to knowledge, our belief is singular.

However, Lin Yujing did not accept Li Zheng's goodwill.

Instead, she gritted her teeth and turned to glare at her own paper.

Nervous.

So flustered she was about to explode.

Li Zheng couldn't help but shake his head.

I've given you an out, ready to forgive you.

And you're still like this.

Won't look at you anymore.
