Liu Sen suddenly stood up and shouted, "Teacher Li, wait a minute." ”

"That...... Who" Li Dejin didn't remember Liu Sen's name for a moment, "What's the matter?"

"Teacher Li, there has been no math test in our class for a long time. ”

"What do you mean?"

Li Dejin is a little confused, this student will not ask for a test, he has been teaching for more than 20 years, and he has never encountered this kind of demand.

"Why don't you do a quiz, it's better to be harder. ”

This was said in front of the whole class, and many students wanted to kill Liu Sen in an instant.

The light in the soul array is proof, I rub it, this hatred value is even higher than the envy value, 1000 bursting table.

Liu Sen flipped through it, didn't forget to glance at Jiang Xue, and said in his heart that you might as well take a math quiz in a class.

If Jiang Xue knew that he thought so, she would have to hit her head against the wall.

Li Dejin was stunned for a while before he reacted, and said: "Now is the critical period to catch up with the progress of learning, and when I wait until the third year of high school, there will be a monthly exam every month, and there will be an unfinished exam." ”

"Then Mr. Li, you just haven't been preparing for the test recently?"

Liu Sen was disappointed.

"The students listened carefully to the class, kept up with the progress, and never fell behind and stabilized their mentality. Li Dejin shouted at his classmates, and stopped paying attention to Liu Sen after speaking, this student must have something wrong with his brain.

As soon as the teacher left, there were hateful eyes.

Liu Sen is happy, come on, come on, let the hatred come more violently.

Waves of hatred energy surged towards Liu Sen, and finally directly reached 2,000 spiritual power.

Students, how much do you hate exams?

But what should Li Dejin do if he doesn't take the exam?

Yuan Gang pushed the thick glasses at the bottom of the wine bottle, the corners of his mouth twitched, and he muttered: "Brother, you are my brother, it's not good if you don't take the exam." ”

Jiang Xue also found an opportunity and asked curiously, "Didn't you always think that our elementary knowledge was very low?"

"Just this morning, a little thing touched me, so I decided to change. ”

Liu Sen said incomprehensibly.

Damn, it's a stupid hat to spend so much spiritual power to brush up on high school math and not use it to earn more spiritual power.

The investment must be rewarded, of course

In order for Mr. Li to be able to take the exam, Liu Sen made an important decision in his life.

He went to the principal to report it.

"Principal You, I want to report with my real name, Teacher Li hasn't given us a test since the midterm exam, it's not enough to just catch up with the learning progress, how can you test the knowledge if you don't take the exam?"

Liu Sen's words made Principal You's eyes widen, and he said in his heart, there is such a fresh and refined student in my school, this student must be a super scholar.

"Little classmate, your suggestion is very reasonable, you have to take the exam to grasp the progress, your opinions are known to the school, and I will definitely urge Mr. Li to improve. ”

Liu Sen left happily.

Li Dejin was preparing a lesson plan when he received a call from the principal, and after listening to the principal, what the hell is the black line on his end? What the hell is this Liu Sen doing, and the anger in his heart still can't be released.

Once, he Li Dejin was nicknamed the exam maniac, a small test in three days, a big test in five days, the students cried and called their mothers, and the students suspected Rensen, but I didn't expect that one day he would be reported by students for not taking the exam.

I......

Li Dejin didn't take a breath, and his heart twitched, wow, it's so distressing.

It took half an hour to recover.

What the hell do you want to take as a garbage student?

Okay, you want to take the exam, right, I'll let you know how good I am.

Out of the foreign appearance, and then reprimand you fiercely.

I rubbed it, after Liu Sen went to report Li Dejin, he waited for a long time and didn't receive a system prompt, I have to sigh, the teacher is the teacher, look, this moral cultivation, I don't hold a grudge when I am reported by my real name, and the teacher is very virtuous.

Math class.

Li Dejin wrote an example question on the blackboard, his board book was extremely powerful, and the blackboard was so strong that it was so dry that the blackboard sounded, obviously today's strength was even stronger, and the blackboard was so dry that it was unbearable to tremble, and finally, he finished writing.

It is known that the moving line L of the origin and the circle C1:x2+y2-6x+5=0 intersect at different points A and B, and the coordinates of the center of the circle are solved, and the trajectory equation of the midpoint M of the line segment AB is solved, and there are three problems, such as whether there are real numbers.

Very complex and cumbersome analytic geometry.

Looking around, it was obvious that I was going to ask the students to answer.

Li Dejin looked around and said, "This topic is a bit out of outline, but it is a particularly good question, which student knows the solution?"

Every time he says this, but every time no one really raises his hand to answer, waiting for him to order Qiao Yu to get up, this is all a routine.

Li Dejin saw that Liu Sen had kept his head down and had never listened to the class, and his face was calm at this moment.

It's just that the system has a prompt: "Get Li Dejin's hate energy +10." ”

I'll let me go, Mr. Li, it's not easy to earn you some energy.

Liu Sen sensed that he raised his head, and the eyes of the two met in the air, and Li Dejin smiled slightly.

Just as he was about to get it, he suddenly saw Liu Sen raise his hand, and he couldn't help frowning, and said in his heart that this student has a special function, and he knows that I want him.

"Hurry up and get out, don't raise your hand to go to the toilet, go quietly and go in." ”

The tone is a bit harsh, and I hate students going to the toilet halfway.

Liu Sen's hand was still raised.

Li Dejin was a little angry.

"Teacher, I want to answer this question, can I?"

"You know, just come up and talk about it. ”

Qiao Yu also raised his head and looked at it, and said in his heart, what kind of wind is this guy smoking, robbing my girl, and stealing my limelight.

"Collect Qiao Yu's Hate Energy +100......"

I'm grass, Liu Sen was so happy, sure enough, for Qiao Yu, it is much more important for a scholar to be in the limelight than a girl.

Liu Sen glanced at Jiang Xue, and said in his heart that you might as well have a math problem.

Everyone stopped to watch how Liu Sen behaved as a demon, and said in their hearts that this guy was dying all day long, wouldn't it be Jiang Xue who made him insane, or bought a lottery ticket and won the jackpot to change Rensen.

Only Jiang Xue was overjoyed, and she almost applauded hard.

Liu Sen took the chalk brush and began to write.

"The circle equation is processed by a formula, and it is easy to get the coordinates of the center of the circle, and then some basic geometric knowledge is used......"

Li Dejin didn't expect Liu Sen to really be able to write it, he was stunned for a moment, his face remained unchanged, and he was about to drive him down.

Liu Sen continued: "Although this method can be made, it is too low, and there is actually the following solution to this problem, adding the problem of auxiliary line conversion. ”

The second solution.

The third solution.

The fourth solution.

"There is also a solution to this problem, which involves the knowledge that has not yet been learned, which is more concise and clear, I will tell you about it first, and then confirm it when I learn that part of the knowledge. ”

Liu Sen spoke again.

It took a while for Li Dejin to react, coughed, and said, "That's a good point, you can go down." ”

Liu Sen said seriously: "Teacher, can you not explain such a simple topic in class, the students' time is very precious." ”

A wave of hatred hits.

The soul array was shining for a while, Liu Sen was so comfortable that he was about to tremble, classmates, it's very powerful, I love you!

The balance of spiritual power has reached 2500.

Liu Sen faced those hateful eyes, and sincerely bent down and bowed, "Thank you." ”

Only Jiang Xue was very excited, she could hardly restrain herself, tears welled up in her eyes, she was the first person to know that Liu Sen was a great master, what a glory.

She really wanted to say: I'm proud!
