Top Students Don't Need Superpowers

"Can this kind of problem be figured out?" Er Nai said in an irritable tone.

"Of course." Asakawa Naoki said, "May I show you?"

"No." Er Nai gritted his teeth and sat back on the sofa, "I will figure it out myself."

The living room became quiet again.

"Sanjiu."

Asakawa Naoki suddenly shouted.

"Huh?" Sanjiu looked up, "What are you doing?"

Naoki Asakawa said, "Don't bite the pencil."

"Why can't you bite?" Clover asked curiously.

"Bitting on pencils can lead to lead poisoning."

Er Nai, who was frowning and competing with the cow to eat grass, was startled when he heard the words, couldn't help laughing, and said disgustedly: "Hey, you are an idiot, aren't you?"

"The stuff in a pencil is graphite, not lead!"

"It's as if there is no crab meat in the crab meat, but it is actually fish meat. A piece of crab meat is so big, how many crabs are needed to make it!"

"That's right." Yihua took a bite of the cake and said vaguely, "Rare earth is not earth either."

May said: "The teacher said that soda ash is not an alkali, but a kind of salt."

Sanjiu raised her hand and rolled up the blue hair beside her ear, and said in a flat voice, "A whale is not a fish."

"Hey?" Yotsuba looked left and right, faltered for a moment, then suddenly her eyes lit up and said, "Yes... a single dog is not a dog."

"stare--"

The five sisters looked at Asakawa Naoki together.

Asakawa Naoki's face sank: "What do you see me doing?"

"Student Asakawa knows it well."

"..."

"It's true that the lead of the pencil is graphite." Naoki Asakawa said with a blank expression, "But the paint on the outside of the pencil contains a small amount of lead."

The reason why pencils are named after lead is that in ancient Rome, people really used lead blocks to write. The upper-class nobles were prone to lead poisoning, and if they were not careful, they would have crooked eyes and dementia.

In the [-]th century, graphite was accidentally discovered. Because the technology at that time was not developed, the difference between graphite and lead could not be recognized, so graphite was mistaken for "black lead". Hundreds of years later, the name of pencil has been spread like this down.

Lead poisoning from biting pencils is not alarmist. In fact, there are many examples of lead poisoning caused by sucking pencils in pediatrics. So biting pencils is not okay, but you can bite refills.

Asakawa Naoki looked at Sanjiu: "So, don't bite again in the future."

Sanjiu pursed her pink lips and looked away: "... Got it."

five minutes later.

"No way."

"Can't do it."

"Student Asakawa is too good to be playing with us like this."

"While the grass grows, it will be eaten at the same time..." Yotsuba looked up at the sky and muttered to herself, "It's so pitiful."

Poor your sister, the cows are squeezed around every day, why don't you say you are pitiful!

The five sisters were wiped out, and Naoki Asakawa achieved a five-kill streak.

"Hey, bastard Asakawa." Nino clasped her hands in front of her chest, and said irritably, "This question is really a primary school math question? You didn't lie to us, did you?"

Naoki Asakawa did not argue, took out his mobile phone, found the original question on the Internet, and handed the mobile phone to the five sisters.

"look by youself."

"..."

A shameful blush soon appeared on Er Nao's face.

I'm really sorry that a sophomore in high school couldn't even solve a fifth grade math problem.

"Will you bet and admit defeat?"

Naoki Asakawa looked at Nino.

"Hmph, of course." Er Nai turned her head and snorted, "Of course I mean what I say."

……

After getting rid of Er Nai, the biggest thorn, the teaching task can finally start smoothly.

"Give me the test papers for your entrance exams first."

Asakawa Naoki said that he already had an idea in his mind about how to teach.

After carefully reading the examination papers of the five sisters, it was as expected as Ninao said, none of them reached the passing line, and the one with the best score was Sanjiu, who scored thirty points in the history exam... A little more, maybe you can pass.

However, with Sanjiu's personality, even if the exam is all history of the Warring States period, in order not to attract attention, she will still make mistakes on purpose, right?
