Lu Mian didn't know Sui Yuan's intentions, and his fingers quickly went back.

[May you not make trouble, the exam number in the examination room has been arranged, and you can't change it. ] 】

[Others can't change it, but you can!] 】

Lu Mian smiled, staring at the text message as if he saw Sui Yuan shaking his little bald head and sly smiling at her.

[How many points do you want?] She replied.

[It's better than Lu Xinnuan's exam! ] 】

Lu Mian: ......

Why is this so related to Lu Xinnuan again?!

Before she could say anything, Ding Chai stood at the back door of the classroom and waved at her.

"Lu Mian, come to my office."

"I'll ......"

Lu Mian rubbed his eyebrows, Teacher Ding has nothing to do every day, he has to stare at her.

She slowly put her phone in her pocket, put her hands in her pockets, and followed her to the office.

Without Sun Jiaying's physics group office, the atmosphere is harmonious.

Ding Chai pulled out a stool for her, lowered his voice and said cryptically and mysteriously: "Tomorrow's monthly exam, or I'll mark a few key points for you......"

"......" Lu Mian's mood was quite complicated.

She lit circles on the ground on her toes at will, and said calmly and lazily: "Teacher Ding, I don't need it." ”

Ding Chai: "......"

His blood choked in his throat, and a few teachers walked into the office, and he had to swallow it back.

"Have you printed the admission ticket for your class competition?"

"Not yet."

"Teacher Ding has a printer over there, pass it to Teacher Ding and type it out."

As they said this, they looked back at Ding Chai: "Teacher Ding, I'm sorry for you, it just so happens that you also printed out your class." ”

"Our class ......"

Ding Chai knew that no one in their class took the initiative to sign up for the competition except for Lu Mian. The knowledge mastered by the first year of high school is not enough, and participating in this kind of competition is either a top student or a cannon fodder.

But Lu Mian didn't take the initiative to hand in the registration form, and he didn't ask again.

After all, with Lu Mian's historical achievements, it doesn't make much sense to participate or not.

A few of the teachers over there were still sighing.

"In this competition, our class is hopeless, and the top students in the third (1) class of high school are not paper-paste."

"Run along, you can't sign up for no one, that's a shame!"

"That's right! Mr. Ding, what about you? A teacher shifted his gaze to Ding Chai here, and then remembered something, and hurriedly said, "I forgot, you are class 25." ”

The other party is straightforward and fast-talking, and there is not much malice.

But the vague meaning of the class 25 representatives was understood by all the teachers present.

The young and newly appointed Ding Chai had an embarrassed expression, scratched his head and smiled, not knowing what to say.

Lu Mian gathered his good-looking eyebrows, and suddenly interrupted him, his voice faint: "Teacher Ding, can I borrow your computer?" ”

“…… Later, I'll give these teachers an admission ticket first. ”

"Teacher, I have a question, I'm in a hurry." Lu Mian insisted.

"What's the problem?"

Ding Chai leaned over while operating the computer.

"That's the physics problem." Lu Mian wrote a string of words on the paper and pushed it over.

[Find a rigid earth with a mass of m and put it in free space...... (PS: The title comes from the Internet, after all, this author is a physical waste...... ）

Ding Chai was just looking sideways, but when he saw this question, his eyes lit up.

He was a physics teacher, so he was naturally interested in physics problems.

"The computer is for you, I'll take a look at this question first." Ding Chai gave up the computer very well.。。

Lu Mian sat down, gently snapped the direction of the screen, and his fingers flew on the keyboard.
