The daughter of a wealthy family who had been reborn earned a lot of money

Maybe it was all influenced by Lu Yuxi's words, all the senior three entered the crazy review process. The principal was very pleased to see it. He was very happy that the leadership made this decision to allow the students to make such a reaction. I also thank Lu Yuxi. Excellent and short speeches by classmates.

However, the school like a bolt from the blue has another super problem. It is a joint problem set by well-known professors across the country. It is said that such a super problem may also occur in the college entrance examination this time, so that the students who originally planned to gear up and plan to work hard for the remaining half a month. The child sighed loudly.

The same thing happened in Lu Yuxi's class.

The class teacher said with a smile on the podium, Students, I have two news here, one good news and one bad news. Which one do you want to hear first?

The students thought about it and decided to listen to the good news first.

The class guide said excitedly: Our class unexpectedly won the first place in the whole school in the liberal arts and sciences test this time. It has been three years and we are the tail of the crane. I didn't expect to get the first place this time. The school gave out a bonus to We, so, I plan to go to the Qinghe BBQ next week, what do you think?

The classmates cheered excitedly for a while, and they all cast a thankful look at Lu Yuxi. If it wasn't for Lu Yuxi's guidance, they would have been the tail of the crane.

Only Lu Yuxi has been sitting there calmly. If you guessed correctly, the bad news should be that super problem!

What's the bad news? A classmate responded and asked.

The class leader's face also became heavy, and he started to write something on the blackboard without saying anything. When Lu Yuxi saw the front, sure enough, it was such a super problem.

She remembered that this question was also a question in her previous life. It was a super difficult problem that the school spent a lot of money on asking the most senior professors in the country.

A similar question to this question also appeared on the college entrance examination paper.

This problem is really difficult. Although those senior professors have made this super difficult problem, so far there has not been a relatively simple method to solve it, and it was only after many days of research that an easy method was found.

Of course, Lu Yuxizao, who has experienced one life, has mastered the simple methods and essentials thoroughly. She remembers that in the last life, she used to use this type of question type as practice questions.

Seeing that the class guide wrote a lot on it, they just didn't understand it.

Teacher, what kind of ghost drawings are you drawing on it? Why can't I understand it? The students who were slow to study couldn't help asking.

Class guide: ...

Teacher, this seems to be a math question, aren't you teaching Chinese?

Class guide: ...

The class leader continued to write speechlessly. At the end of the writing, he actually forgot. There was a contradiction in his heart. He stopped the chalk in front of everyone's eyes. He just read it several times before he remembered it. When he was interrupted by these little bastards, he forgot everything. .

Watching the class guide stop the chalk for a long time, the naughty classmate couldn't help but tease: Teacher, are you getting old and forgetting everything?

The class guide was speechless again ...

In fact, the class guide is just a 24-year-old female teacher named Xu Yuan. She is graceful in appearance and as delicate as a book. She is very kind to all the students in the class, so the students are willing to joke with her, and Lu Yu loves her. In the last life, when Lu Yuxi was said to be plagiarizing, she explained to her several times that she was not that kind of person, but it didn't work.

Her youth also made her the target of bullying by many teachers. Even if there were more than 20 classes in our class, and how much she was ridiculed by other teachers, she smiled and cheered for us. This is a sense of responsibility. teacher.

Looking at the teacher's tangled appearance, Lu Yuxi couldn't help but reminded: F=Y㏄.

The teacher suddenly realized that he continued to write, and halfway through writing, he suddenly looked at Lu Yuxi with doubts.

The classmates looked at Lu Yuxi strangely, but Lu Yuxi ignored them and rested on the table.

Classmates, look at the blackboard, this is the bad news I have to tell you

Yang Ran was puzzled: Teacher, why do you say this is bad news?

The class guide explained patiently: This question is a new super-difficulty problem from the school recently. The question is written by the most senior professors in the country, and this question may appear in the exam questions of the college entrance examination. Since it is really difficult, it is difficult to learn to ask questions. The test questions let you try to write, and tell you, this question may account for about 25 points in the test paper.

What? So much? I can't even see what it is, so how do we write it? Didn't I lose 25 points in vain?

That's right, looking at Lu Yuxi's daze, it seems that he doesn't even know the genius who is number one in the school. It's over, don't even think about going to a good university.

Seeing that the students were all very frustrated, the class director also said at a loss: It's okay, there is an answer to this question, but it's a bit complicated and it may be a little difficult to understand.

The students said in surprise: Quick, class guide, write it out for us to see.

The class guide bit the bullet. She was a Chinese teacher and asked her to write mathematics. Although she had listened to all the questions when they came out, it was still very difficult. She didn't understand it at all, so she could only write it on her back.

Ten minutes later, the class teacher finished writing and stopped writing. The students were dumbfounded. They couldn't even read such a blackboard. How could they understand it?

Class guide: ... She's just a language teacher, and she doesn't know anything about math, so she can only hold big eyes with everyone.

The classroom was unusually quiet, as if time had stopped at this moment.

At this time.

Lu Yuxi couldn't bear it anymore, and stood up from the seat, her classmates didn't care, thinking she was going to the toilet, but when she stepped onto the podium, her classmates were not calm.

The class guide asked, What's wrong with you, Lu Yuxi? Do you have anything to say?

Lu Yuxi: No, teacher, I have a request, I wonder if you can agree?

what?

Teacher, can you sit in my seat? Lend me the podium? Lu Yuxi asked unceremoniously.

Although I wanted to ask why, the class guide still agreed.

After seeing the class guide sitting down, Lu Yuxi covered her mouth, picked up the blackboard eraser, and began to erase from left to right. The height of 168 allowed her to erase very good questions easily, leaving only the questions and The students and class guides who have not responded yet.

Xiaoxi, what are you doing? Why are you rubbing her well? Yang Ran asked.

Lu Yuxi didn't answer, but said, From now on, I'll just say it once, remember what you like to remember, and stay quiet and don't make noise if you don't like to remember!

After speaking, he answered the question in the black class: What I said, it's best to remember what I wrote, record the F here as 1, which is the easiest to calculate, and compare the Y to?... Then...

Perhaps it was Lu Yuxi's confident and clear explanation and analysis. The classmates nodded and took out their notes, and even the teacher wiped out Lu Yuxi's notes and took them down.
