Maybe they were all influenced by Lu Yuxi's words, and all the senior high school students entered a crazy review, and the principal was very relieved to see it, and he was very happy to see that the leader made such a decision to let the students make such a reaction, and also thanked Lu Yuxi for his wonderful and short speech.

It is said that such a super problem may also appear in the college entrance examination this time, which made the students who originally planned to work hard in the remaining half a month sigh all of a sudden.

This is also the case in Lu Yuxi's class.

The class teacher smiled on the podium and said, "Students, I have two pieces of news here, one good news and one bad news, which one do you want to listen to first?" ”

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

The class guide said excitedly: "This time, regardless of the arts and sciences exam, our class unexpectedly won the first place in the school, three years, we are all crane tails, I didn't expect to win the first place this time, the school gave us a bonus, so, I plan to go to the Qinghe River next week for a barbecue, what do you think?"

The students cheered excitedly for a while, and they all cast a grateful look at Lu Yuxi, if it weren't for Lu Yuxi's guidance, they would still be the tail of the crane.

Only Lu Yuxi has been sitting calmly, if you guess correctly, the bad news should be that super problem!

"What's the bad news?" a classmate asked.

The class guide's face also sank, and without saying anything, he began to write things on the blackboard, and when Lu Yuxi saw the front, sure enough, it was really such a super problem.

She remembers that in her previous life, it was also this problem, and it was a super problem that the school spent a lot of money to invite the most senior professors in the country.

This question is similar to the one that appears on the college entrance examination paper.

This problem is indeed difficult, although those senior professors have made this super problem, but so far there has been no relatively easy way to solve it, or after many days of research to find the easy way.

Of course, Lu Yuxi, who has already experienced a lifetime, has already mastered the simple methods and essentials very thoroughly, and she remembers that in her previous life, she often used this type of question as a practice question in her previous university.

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

"Teacher, what the hell are you drawing on it? Why can't I read it? Students who are slow to learn can't help but ask.

Class Guide: "..............."

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

Class Guide: "......"

The class guide continued to write speechlessly, and at the end of the writing, he actually forgot, there was a contradiction in his heart, he stopped the chalk in front of everyone, and he just read it many times before he remembered it, and he was interrupted by these little rabbit cubs and forgot everything.

Watching the class guide stop the chalk for a long time, the naughty classmates couldn't help but ridicule: "Teacher, are you old and forget everything?"

The class guide was speechless again "......"

In fact, the class guide is just a 24-year-old female teacher, named Xu Yuan, she looks like a gentleman, bookish and delicate, she is very good to all the students in the class, so the classmates are willing to joke with her, Lu Yuxi is taken care of by her a lot, when Lu Yuxi was said to be plagiarized in the previous life, she explained to her several times, saying 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 our class had more than 20 classes, how much she was ridiculed by other teachers, she smiled and cheered for us, this is a responsible teacher.

Looking at the teacher's tangled appearance on it, Lu Yuxi couldn't help but remind: "F=Ycc".

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

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

"Students, look at the blackboard, this is the bad news I want to tell you"

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

The class guide patiently explained: "This question is a new super problem in the school recently, by the most senior professors in the country together, and this question may appear in the college entrance examination questions, because it is really difficult, so learn to send the test questions for you to try to write, and tell you that this question may account for about 25 points in the exam paper." ”

"What? So much? I can't even read what it is, so how can we write it? Didn't you lose 25 points for nothing? All of a sudden, the students below exploded.

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

Seeing that the students were all very frustrated, the class guide was also a little overwhelmed and said, "It's okay, there is an answer to this question, but it's a little complicated and may be a little difficult to understand." ”

The students were pleasantly surprised and said, "Quick, class guide, write it out and show it to us."

The class teacher wrote hard, she was a Chinese teacher, and asked her to write mathematics, although she listened to all the questions when she came out, but it was still very difficult, she didn't understand it at all, and she could only write it by memorization.

Ten minutes later, the class guide finished writing, stopped writing, and the students were stunned, such a blackboard, they couldn't read it, how could they understand it?

Class Teacher: "........." She is just a Chinese teacher, and she doesn't know anything about math problems, so she can only talk to everyone.

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

Then.

Lu Yuxi couldn't help it, got up from the seat, and the classmates didn't care, thinking that she was going to the toilet, but when she walked up to the podium, the classmates were not calm.

The class guide asked: "What's wrong with Lu Yu?" Is there anything you want to say? ”

Lu Yuxi: "No, teacher, I have a request, I don't know if you can agree?" ”

"What?"

"Teacher, can you come and sit in my place? Lend me the podium? Lu Yuxi asked unceremoniously.

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

After seeing the class guide sit down, Lu Yuxi covered her mouth, picked up the blackboard to erase, and began to wipe from left to right, the height of 168 made her easily wipe the question, leaving only the question and the classmates and the class guide who had not yet reacted.

"Xiao Xi, what are you doing here? Why are you wiping her well? Yang Ran asked.

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

As he spoke, he answered the question in the black class: "I said that it is best to memorize what I wrote, and remember F here as the easiest to calculate 1, and compare Y to ?...... And then..."

Maybe it was Lu Yuxi's confident and clear explanation and analysis, the students nodded and took out their notes to take them down, and even the teacher erased Lu Yuxi's notes and wrote them down.
