As soon as Mr. Li's voice fell, many students raised their hands one after another.

Students with good academic performance are conceited, how can they easily admit defeat.

"Classmate, who do you want to challenge?"

Le Yan glanced at the crowd and saw that one of the boys had the highest hand raised, just now he was holding the workbook for Teacher Li to help solve the problem, Huanggang Secret Problem Collection, so he smiled and said:

"Just this classmate with the Huanggang question in his hand."

The boy was named, with an obvious and excited look.

Teacher Li smiled:

"My classmates don't know your name yet."

"Leyan." Le Yan replied.

Teacher Li said:

"Le Yan, Xu Cheng's Huanggang collection is quite difficult, why don't we compare it with a classic physics problem in it, it just so happens that I, as a physics teacher, can be a judge for you, what do you think?"

Of course, Le Yan said that he had no objection.

Teacher Li took the workbook from Xu Cheng's hand, flipped through it, and found a friction question after consideration.

Then he took a picture of the topic with his mobile phone and brought it to Le Yan's eyes.

Xu Cheng looked gearing up, he had been focusing on tackling this type of question before, and he had gained a lot, and he was very confident in this.

Le Yan glanced at the topic and understood it in his chest.

This question is indeed difficult, it can not only test the basic skills, but also challenge the flexibility of thinking, it is indeed a good question to test the learning level, and Mr. Li is really good at selecting the topic.

"Ten minutes per person, any objections?" Teacher Li asked.

Le Yan felt that ten minutes was quite sufficient, but now ten minutes was a bit long, because the four-by-hundred-meter check-in time was about to pass.

Teacher Li seemed to think of this, and continued:

"This four by 100 meters, our class will abstain, but Le Yan, you will not challenge in vain, if you win, the next project, no matter what it is, our class will send people out."

"Okay, thank you, Mr. Li." Le Yan said.

The ten-minute countdown begins.

Xu Cheng was extremely serious, quickly reviewed the topic, and then started to write and draw on the scratch paper, and a circle of classmates sat around him, all silently cheering him on.

Le Yan sat on the other side, in fact, he had just finished reviewing the question, and the answer was already in his head, but out of respect for his opponent, Le Yan still made a thinking look.

The liveliness of the sports meeting was in stark contrast to the quietness of the class at this time.

Le Yan sat like this for five minutes, she felt that the time was almost up, and glanced at Xu Cheng next to her, Xu Cheng's forehead was about to be pinched out by himself, and fine and dense sweat appeared on the wings of his nose.

Le Yan took a long breath, then picked up the pen, and on the scratch paper, began to write the problem solving process neatly.

At this time, some of the onlookers still couldn't help whispering:

"You see, that girl didn't even make a draft, so she started writing."

"It's really fake, bluffing, this question is a bit out of the outline."

Some people whispered, and some people actively copied the inscriptions, and began to write while doing the math on the scratch paper.

The learning atmosphere is getting stronger and stronger, and the atmosphere of the competition is also more intense.

Soon, Le Yan stopped writing, and she sat there without speaking, quietly waiting for the countdown to end.

And Xu Cheng's mentality gradually collapsed, there were still two minutes left, Xu Cheng crossed out all the steps he had written before in the surprise of everyone, and he was ready to start writing again.
