"The source is in this coffin!" Lu Fei pointed to the coffin and said.

He saw puffs of black gas coming out of the coffin, which was emitted by corpse poison.

"Strange, why did your second uncle and grandfather come here? He can't be a grave robber! Lu Fei said jokingly.

In fact, he felt that Zhang Haitao's second uncle and grandfather should not be tomb robbers.

If it is really a tomb robber, who would steal something from such a place, there is nothing valuable in it at all.

"I don't know!" Zhang Haitao said embarrassedly.

"I didn't bring anyone or magic weapons today, let's come early tomorrow morning!"

"Good!" Zhang Haitao nodded.

Early the next morning, Zhang Haitao drove Lu Fei to this place again, and he also found more than a dozen migrant workers.

Lu Fei gave each migrant worker a talisman to stick on their bodies, and then began to dig up the coffin and place it on the ground.

Opening the lid of the coffin, Lu Fei found that the people inside were about to turn into zombies.

"No wonder the corpse poison in your second uncle and grandfather is so powerful, it turns out that this corpse is about to turn into a zombie!"

Lu Fei said as he took out the peachwood sword and plunged it into the corpse's heart with a "poof".

"It's over! Your second uncle's corpse poison should be solved! Lu Fei clapped his hands.

"Master Lu, thank you! My second uncle and grandfather said that I want to invite you to dinner today! ”

"Forget it! I'm still in business! I won't go! Lu Fei waved his hand.

He still has to go to school today, and then he has to go home to set up the formation, what if the ghost sends a joint Yin soldier to find him and ask Cao De.

Lu Fei is not afraid of three or five Yin soldiers, but there are many Yin soldiers, and Lu Fei really doesn't dare to fight them.

This is like no matter how powerful a master is, he can't withstand thousands of troops, otherwise the country would have been controlled by the master a long time ago.

When he came to school, Lu Fei heard about something, and Gu Yan asked him to participate in the National Mathematics Competition.

There are a total of three places in the whole grade, including one of them.

Lu Fei felt that Gu Yan was really fighting for his reputation.

The last time they chatted, Lu Fei said that he could steal the answers to many exercises through Taoism, and he should be able to enter a very good school during the college entrance examination.

Gu Yan wanted Lu Fei to help him participate in the National Mathematics Competition, and if he won the award, he would be promoted to the deputy director of the Education Bureau.

At that time, Lu Fei thought that he was just talking casually, but he didn't expect Gu Yan to take it seriously.

Just when Lu Fei was about to find Gu Yan to push away this matter, a boy with glasses rushed in outside the classroom, he pointed at Lu Fei and said, "Lu Fei, you come out, I want to compete with you!" ”

Lu Fei looked at the boy inexplicably: "Compared to what?" ”

"Math, of course! If it weren't for you, I would have been able to participate in the math contest this time! ”

It turned out that the boy's name was Wang Kang, and his math score ranked third in the school.

Originally, he and two other classmates were determined in this mathematics competition, but because of Gu Yan, Wang Kang's quota was allocated to Lu Fei.

Lu Fei understood that the other party was not angry and came to him to fight in the ring.

He immediately comforted Wang Kang: "Don't worry, I won't go to the math competition." I'll go to him in a moment and ask him to give you your place. Good no good? ”

"No! I'm going to compare myself to you! I want everyone to see that my Wang Kang's mathematics is ten, hundred, or even a thousand times stronger than yours. ”

Wang Kang dog bites Lu Dongbin and doesn't know the hearts of good people, so he stood in front of Lu Fei and shouted loudly.

Lu Fei furrowed his brows, thinking that this guy was a tendon.

"Wang Kang, let's not compare. I definitely won't attend. ”

"No! I'm going to compare you today! ”

Wang Kang held his head high and said in a fierce voice.

I grass! It's endless, isn't it? Lao Tzu let you, do you really think that Lao Tzu is a soft persimmon that is easy to pinch!

Wang Kang completely Lu Fei.

He slapped the table and got up from the stool: "Damn, it's better than it, I'm afraid of you!" ”

Immediately afterwards, Lu Fei said: "Hurry up and talk about how to compare, I don't want to waste time with you." ”

"Good! Joyfully! I make a question, you make a question, I do your question, you do my question, three games and two wins! ”

"Hurry up and get the question!"

"Lu Fei, you can find the maximum and minimum values of this question!"

Wang Kang came up with an extremely difficult question, and looked at Lu Fei with a sneer on his face, he felt that Lu Fei would definitely not do it.

Lu Fei glanced at Wang Kang's question.

This is a question about the limit value of a function, which requires very strong divergent thinking and spatial conception ability to answer.

If it was before, Lu Fei would definitely be defeated.

But now it was different, he chanted the incantation, let his soul out of his body, and quickly ran outside to look through the answers.

After a while, Lu Fei found the answer: "The maximum value is 3, and the minimum value is the root number 2." ”

Yes? What the? He actually did the right thing! How is this possible?

Wang Kang was extremely surprised and looked at Lu Fei in disbelief, he didn't expect that the problem he had spent more than twenty minutes to solve, Lu Fei would get it right in a few minutes.

When the other students saw this question, they shook their heads and gave up the idea of answering it directly, they felt that it was too difficult.

When they saw that Lu Fei gave an answer after just one glance, they thought Lu Fei was talking nonsense.

They didn't believe that Lu Fei could solve it in such a short time.

"You're in luck! You have the question! Wang Kang felt that Lu Fei must have taken shit luck, otherwise it would be impossible to answer it so quickly.

Hearing Wang Kang's words, the onlookers were extremely surprised.

What the? Did Lu Fei do it right? Impossible! How could he be right on this topic when it was so difficult? It's incredible.

In particular, a few students in the class who had better math scores than Lu Fei felt even more incredible.

They just thought about it for a while, not to mention that they couldn't solve the answer, they didn't have any ideas to solve the problem.

"No need! You'd better just give me the question! As long as I don't get one of them right, then I lose. ”

Lu Fei waved his hand and said confidently.

Wang Kang felt that he had been greatly insulted, because according to the rules, one person made a question and did it crosswise, but Lu Fei did this, obviously looking down on him.

However, he felt that Lu Fei was killing himself, so he did not continue to adhere to his principles.

"You can solve this problem!" Wang Kang came up with an even more difficult question.

This is a probabilistic problem, which requires not only very rigorous logical thinking, but also strong computing power.

If one of these small links is wrong, the answer will be lost.

"Is that all you have? Another such a simple question! Lu Fei sneered disdainfully, and then showed a thoughtful look.

In fact, his soul had left his body.

Five minutes later, Lu Fei's soul returned, he picked up the pen and pretended to start counting on the paper, and then gave the answer on the spot, "The probability of this question is 1 in 30.89 million." ”

When Lu Fei said the first half of the sentence, Wang Kang felt that Lu Fei was a forklift.

Even the teacher may not be able to solve this problem correctly, let alone Lu Fei.

When he was about to ridicule Lu Fei, he heard the answer given by Lu Fei.

What the? How is this possible?

Wang Kang couldn't believe his ears and looked at Lu Fei in disbelief, he felt that this was really incredible.

"Lu Fei, what are you doing? Do the math! Liu Shiya felt that Lu Fei was too hasty.

First of all, it takes time to clarify the logic of this question.

Secondly, this problem requires a lot of calculation steps, and each step requires the help of a computer to figure it out.

She felt that Lu Fei could not give an answer in just a few seconds.

The other students thought the same as Chu Yanran, thinking that Lu Fei was too capable of pretending.

"This is the correct answer, if you don't believe it, ask Wang Kang!" Lu Fei looked at Wang Kang with a smile.

All eyes focused on Wang Kang's face.

When everyone saw Wang Kang's pale face and shocked expression, they all thought in their hearts:

No way! Could it be that Lu Fei really did it right? But this question is so difficult, how can he finish it in an instant? It's not logical!

"Wang Kang, you tell everyone, did I do it right?" Lu Fei knew that Wang Kang knew the answer, otherwise he would not have asked this kind of question.

"You're just lucky!" Wang Kang forcibly defended.

He doesn't want to believe it's true, because it's not logical, and it's not scientific.

"Humph! You don't care if I'm lucky or not, as long as I do it right! Sometimes luck is also a form of strength. ”

"That's good! I'm going to have the third question now, and I don't believe you can get it right! ”

Wang Kang picked up the pen and began to ask the third question.

This time, instead of a question he had already prepared, he prepared a question that even he and their teachers would not do.

He felt that Lu Fei would definitely not do this problem, unless Lu Fei was a mathematics professor at the university.

At this moment, Principal Gu Yan took several school leaders and accompanied an old man in his sixties to the door of the first class of the third year of high school.

The old man is a mathematics professor at Provincial University, and he came to school today to talk to Lin Lin, a mathematics prodigy from Chuncheng No. 1 Middle School.

Lin Lin's talent in mathematics is beyond ordinary people, and the old man wants to recruit Lin Lin to the Department of Mathematics of Provincial University.

When the old man saw that the first class of the third year of high school was full of people doing math problems, he couldn't help but be interested, and looked at all this with a smile.

"You have the ability to do this problem!" Wang Kang put down his pen and looked at Lu Fei coldly.

Lu Fei glanced at the question and found that this question was indeed difficult.

Seeing Lu Fei's thoughtful look, Wang Kang couldn't help laughing: "Lu Fei, you can't pretend to be able to compare this time!" If you can do this, I'll call you Dad! ”

In Wang Kang's opinion, even the questions that their teachers can't do, Lu Fei definitely won't.

"Really? That's what you said. ”

Lu Fei recited the spell again, and the soul went out of the body to find the answer.

This time, Lu Fei quickly discovered the answer to this question, and after his soul returned to his body, he immediately pretended to perform the calculation on paper.

After a while, Lu Fei stopped his pen and said to Wang Kang: "I will tell you now, the answer to this question is: when A is equal to one-half of B, this equation is true, and A is equal to 2 and B is equal to 4. ”

"You say that's the answer!"

Wang Kang didn't believe Lu Fei's words at all.

Everyone also didn't believe Lu Fei, because this question was too difficult, and they didn't have a clue for a long time.

"If you don't believe it, you can ask the teacher to verify it!"

"Can I come and take a look?" The old man walked in and said with a smile.

Gu Yan and the others also hurriedly followed.
