Lu Mian's fingers flew fast, and the screen of the mobile phone switched wildly.

Ding Chai was about to say something, but suddenly found that she was wearing headphones in her ears, and she didn't hear him at all.

"...... okay, he really played the piano to sleep just now."

After Sheng Zijin's team was introduced one by one on the stage, Sheng Zixin stood in the team, suddenly took the microphone, and spoke quite arrogantly.

"Did any of you solve the math problem two days ago? It doesn't matter if it's the teacher or the student. ”

He is also playing with the school emblem belonging to Kunpeng Middle School!

Listen to this arrogant tone!

Look at this arrogant attitude!

Several school leaders and some teachers sitting in the front row of the theater had cold faces.

The classmates in the audience sighed, blaming themselves and humiliating. I can't wait to kick this group of people out of my campus, but I have to admit that the other party's disappointment made them feel aggrieved for two days!

The more he faced the arrogant enemy, the more Jiang Hua told himself that the more stable he became.

He also took the microphone with great interest, walked to Sheng Zixin's side, and interacted with him on the spot.

"This is Sheng Zixin, I have a question for you."

"Please."

Jiang Hua glanced at the audience, and finally looked at Sheng Zixin seriously, and asked rhetorically: "Is that math problem you came up with, is it difficult?" ”

"......" Sheng Zixin's expression was stunned, as if he was laughed at angrily.

The students in the audience were boiling because of Jiang Hua's words, hanging their chairs and whistling.

I never knew that their head of grade was so naughty!

That's a good question, a wonderful question!

Sheng Zixin also laughed with "haha" at the end: "Do you have any misunderstanding about this question?" ”

What level is his question, can he not know? At the beginning, the teachers of the middle school also got together, and it took a day to get to the essence of the problem and answer it. Because none of the experts of the Olympiad Committee did it within the allotted time, this question became a legend.

They even said that this question is not difficult?

Sorry, he just wants to laugh now.

"Oh, probably not." Jiang Hua smiled first, with a bit of jokingness and was very humble and arrogant: "But I think you may have some misunderstanding about our school." ”

Sheng Zixin and his group looked at each other, and the scene was quite embarrassing.

Jiang Hua ignored it and said into the microphone, "Equipment room, release the surveillance video of the solution." ”

Sheng Zijin glanced at Sheng Zixin, a little unsure, could it be that someone really figured it out?

Sheng Zixin waved his hand, if there were really particularly outstanding students, it would not be impossible for two days, but he would not surpass him after all.

He didn't take it seriously, turned sideways and looked at the big screen behind him.

The surveillance video was quickly played. There is no sound, only pictures.

The picture started when Sheng Zixin was writing the title, and the picture after he finished writing began to speed up, and it was not until twenty minutes later that no one moved on the display board, and the video returned to its normal speed.

The campus is quiet.

Only a tall short-haired girl walked into the camera, she seemed a little sleepy, covering her mouth and yawning all the way, making it impossible to see her face clearly.

Soon, after the girl passed the display board, the plot was reversed.

She paused for a few seconds before picking up the marker that had been thrown on the floor.

Without thinking about it, I put down the pen and began to write the process and answers, and the time of the surveillance video showed 7:22.

She copied her pocket with one hand throughout the whole process, not even a piece of scratch paper, and looked diagonally at the monitor.

By the time the surveillance re-captured the display bar, the puzzle was solved, and the neat answers were listed there.

The time shows 7:28.

Surveillance paused, and at the same time, a frenzied scream erupted in the theater.

"Ahhhhh

"What a problem is this, our school classmates, it's done in six minutes!"

"Times Middle School, give us back our school emblem!"

In the boiling frenzy, someone asked weakly in the audience, "Who is that girl?" ”。

Someone stood up directly and shouted, "I know, I know who she is!" ”
