Xueba God-level system

This is indeed true. Seeing that the countdown to the end of get out of class has entered less than 1 minute, Mr. Zhang Guilin chose to wipe the blackboard at this time, which was a waste of his own time and everyone's time.

Just imagine, if he wasted 1 minute, the whole class of more than 70 people would be worth an hour and more than ten minutes!

As the saying goes, time is life, he managed to get through a class, and at the last juncture, he didn't want the lives of his classmates (time = life).

So, he stared at the blackboard in front of him with piercing eyes, and among the many symbols of words and mathematics, he saw a sacred and pure land.

That is the top of the blackboard, a little bit below the clock.It seemed a bit remote there, except for this clean land, the other places were ruthlessly polluted by the math teacher with chalk.

Although Mr. Zhang is very small, he is not particularly short. Compared with the big boys in the class, he can only be regarded as a younger brother.

But compared with the smallest carrot head in the class, his height is much taller and straighter.Even so, it was still somewhat difficult for him to reach the open space at the top of the blackboard.

"Ding ding ding ding, Dangdang, students, it's time for the end of get out of class, teacher, you have worked hard!"

At this moment, the long-lost bell for the end of class rang on the campus radio.

Wang Binghui stretched casually like baring his teeth and claws, and yawned domineeringly.He didn't think it was very enjoyable, and then he hit it hard again. The range of motion was a bit too big, and he almost knocked out his gums at the same time.

The schoolboys were gently knocked awake by the bell after school, and slowly opened their eyes.

The top students, on the other hand, rested their chins on both hands, and twirled their pens leisurely with the other hand.I always feel that a class is too short, and I can't listen enough, so I can only hope for the evening self-study an hour later.

Seeing the math teacher's dilemma, Wang Binghui already knew that an opportunity was finally in front of him.

If he didn't cherish it, then he would have wasted his plan to meet Brother Pao and play basketball as soon as possible.

I saw Mr. Zhang Yazi who seemed a bit at a loss (look). If he was asked to describe this monotonous interval, it was obviously not as simple as imagined.

Although it is such the simplest knowledge point, he knows more than anyone else.But when he showed the graphical things to everyone in words, it seemed a bit like listening to a book from heaven, and it was in the clouds.

What is monotonically increasing but also decreasing, it increases in this interval, why is it ruthlessly decreased in another interval!

These seemingly abstract questions are still puzzling these young minds.

Teacher Zhang's thoughts were brilliant, and he finally made a decision. It is better to represent the graphics by handwriting, which is easier and more intuitive.Even if it's dragging the hall, there is no wave in his heart, and he has nothing to fear.

In the face of such a solemn and solemn occasion of the college entrance examination, what a delay for a few minutes.Why drag the world if you don't drag one class.This sentence has been imprinted in the depths of Mr. Zhang's mind since his internship.

However, even the screen saver of his mobile phone and his QQ signature quoted this classic and shocking quote.
