After exiting the system, Li Changsheng suddenly felt a sense of relief, and the shackles that had bound him for three years were finally removed.

"In this lesson, we review the curve function, the .......... of the curve function"

The math teacher on the podium is working hard to review the curve function for the students who are sprinting for the college entrance examination.

Li Changsheng subconsciously raised his head and looked at the math teacher, and unexpectedly found that a status bar was displayed on the math teacher's head.

Name: Li Chunhong.

Gender: Female.

Age: 54 years old

Occupation: National Special Teacher.

Ability: [Level 2 Mathematics].

Cash: 250,043.67 yuan

Then there is her age at birth, and some physical conditions about her.

Li Changsheng was not particularly curious about the other data of the mathematics teacher, but this second-level mathematics attracted Li Changsheng's attention.

Li Changsheng turned his head and glanced at Song Yiren, who was taking notes carefully, there was also a status bar on her head, her name, gender, occupation and her physical condition were clear at a glance, the only difference was that her mathematical ability was marked with: [Level 1 Mathematics], [Level 1 Chinese], [Level 1 English], [Level 1 Geography], [Level 1 Chemistry], [Level 1 Physics], and at the same time, her cash was also marked as: 688 yuan.

Looking at the others, their heads are marked with: [Level 0.5 Mathematics], [Level 0.8 Chinese]...........

Only Chen Xin has [Level 1 English] on his head, and the other disciplines are also zero-level disciplines, and his head is also marked with cash: 5,000 yuan.

"This is ....." Li Changsheng's eyes widened a little, and then he noticed that there was an option to devour at the bottom of the status bar of these people.

Li Changsheng hesitated for a moment, and then devoured the mathematics teacher's second-level mathematics.

"Corpse Kun copy!"

"Replication successful!"

"Congratulations to the host for gaining the ability [Level 2 Mathematics]. ”

The indifferent voice of the city's strongest corpse kun system rang out.

Li Changsheng suddenly felt a wave of memories rushing into his head, and this memory was the mathematical knowledge in the mind of the mathematics teacher. You must know that Ms. Li Chunhong has been teaching mathematics for 30 years, and even this self-taught version of the mathematics book was published by her, how strong do you say her understanding of high school mathematics is?

"Hiss~Wow~"

Li Changsheng couldn't help but sigh, he didn't expect that he would take care of the corpse Kun for three years and give himself such a big surprise as soon as he was born, and he instantly mastered all the knowledge points of mathematics in three years of high school.

Hearing the voice next to him, Song Yiren subconsciously turned his head to take a look, and a pair of beautiful eyes suddenly opened up, as if he saw the Pleasant Goat being eaten by the gray wolf.

Li Changsheng noticed Song Yiren who turned his head and looked at him in surprise, and couldn't help but look at her with a smile on his face, his handsome and handsome face hurriedly hid behind the pile of books, and laughed at Song Yiren: "How is it?

Song Yiren smiled and no longer paid attention to Li Changsheng, a shameless person.

When Li Changsheng saw that she was ignoring herself, he couldn't help but sigh and said, "Oh, this world is ........."

And the math teacher standing on the stage, Mr. Li's face was a little displeased, she was now in a review class, and the most annoying thing was that others spoke in class, and it was better to sleep, after all, it would not affect the classmates, but the speech in class would affect the classmates.

She looked up at the place where the whisper was made, and saw that Song Yiren was sitting in a precarious position, and Li Changsheng and classmate Li who were supposed to sleep on the table actually hid behind the pile of books to talk and harass Song Yiren.

She was immediately angry, this Li Changsheng didn't listen to the class, and now he actually wanted to harm Song Yiren, who was most likely to be admitted to the first university in the south.

Her face turned indifferent, and the sound of her lecture stopped, and she immediately shouted:

"Li Changsheng, come up to the podium and give me the answer to this curve function. ”

The whole class instantly turned their heads and looked at the position of Li Changsheng, who had slept for three years.

I saw that Li Changsheng was hiding behind the pile of books, and he didn't know what to say to Song Yiren, which made Song Yiren's face slightly red, like a red apple.

This is a bad thing to make the male classmates in the class angry.

And Chen Xin is also angry, this Li Changsheng must have used the matter of his girlfriend just now to tease Song Yiren.

But then I saw that Mr. Li asked Li Changsheng to come to the stage to solve this curve function, and the corners of his mouth couldn't help but sneer.

Because this curve function is extremely difficult, as we all know, mathematics is a hodgepodge, fusing several formulas into one, and mixing all kinds of misleading statements to form a big problem.

The problem in front of me is first of all a fusion of curve functions, trigonometric functions, space geometry, conic geometry, and auxiliary lines, and then this problem does not have any numbers, which is the so-called common sense problem or life problem, which is similar to the problem of chickens and rabbits in the same cage in life.

This is the most difficult question in mathematics in the college entrance examination last year, countless candidates fell in front of this question, have lost points, it is said that only last year's national college entrance examination champion, only barely answered half of the right, gave half of the points.

Song Yiren's narrow eyelashes flashed above her beautiful eyes, and her willow eyebrows were slightly wrinkled, looking very worried that Li Changsheng might lose face.

How could Li Changsheng, a guy who has slept for three years, answer?

However, in the eyes of everyone looking at the joke, Li Changsheng stood up with a smile and said:

"Okay, teacher!"

The audience was in an uproar.

Everyone was shocked, they thought that Lin Tian would get up and admit that he couldn't do this, and then the math teacher, Mr. Li, was a painstaking educator.

But....... But this one Li Changsheng actually didn't play cards according to the routine!

In the midst of everyone's surprised gaze, Li Changsheng strode towards the podium.

Li Chunhong looked at Li Changsheng, who really came to the stage, and couldn't help but glance him up and down, what did this Li Changsheng eat today, why does the whole person look different?

"If you don't know how to do it, you can just stand by and watch me analyze it for you, and then you can do this problem. ”

Li Chunhong is still a teacher after all, and she doesn't want Li Changsheng to be embarrassed, so she painstakingly finds a step for Li Changsheng.

But Li Changsheng shook his head and said indifferently:

"Thank you, teacher, but this one is quite easy for the students. ”

Li Chunhong frowned slightly, feeling that Li Changsheng's confidence was not pretending, as if he would really do this question.

After Li Changsheng spoke, he picked up a long piece of chalk in the blackboard slot in the eyes of the classmates behind him who were looking at jokes, and then as if he thought of something, he turned his head to Teacher Li Chunhong and said with a smile:

"Teacher, you lend me this teaching triangle to answer!"
