Dealing with thorn-headed students, Li Changan has little experience.

But in his previous life, he had seen a lot of such a student and came to a conclusion.

Most of these students belong to the category of people who are well fed and underpaid.

It doesn't help to be reasonable.

Because they don't bother to listen at all.

So the most important thing is for them to be able to hear what you have to say.

In this regard, Li Changan said that he is very experienced.

Walking into the school that didn't even have a name again, the thirty Bailu students were all there, and they all held their heads high like fighting cocks, eager to pestle themselves with their chins.

Li Changan was all happy.

"Before starting today's schoolwork......" Li Changan's gaze swept over the unruly faces of the thirty students,

"Let's first sharpen the time with the killing intent of a stick of incense."

The corners of Li Changan's mouth hooked up a smile.

The killing intent arrows swirled quietly, and the cold and piercing killing intent was like a late autumn mist, gradually diffusing and converging in front of every Bailu student.

At this time, it was still summer, and the heat should be unbearable, but the thirty Bailu students seemed to fall into an ice cave in an instant.

The body couldn't help but tremble.

Every pore around the body exudes fear.

The unruliness just now suddenly disappeared, and I could only grit my teeth and support it desperately.

"If you can't hold on, just lower your head, and the killing intent will naturally dissipate."

Li Changan stood in front of the lectern and said with a smile.

It's very simple to maintain a murderous intent for a quarter of an hour, you just need to ensure a long stream of water.

But if you target everyone individually, instead of just spreading out the killing intent at random, the difficulty will be several times or dozens of times higher.

Because everyone needs to be in control.

Rao is Li Changan has the killing intent arrow as the core of the killing intent, and he must also fight the spirit of twelve.

If someone can see the killing intent, they will find that at the center of the eyebrows of the thirty Bailu students, each has a killing intent arrow slowly rotating, and it is about to pierce into the flesh and skin.

There was silence in the school, and the expressions of every Bailu student were extremely serious, and even a few of them had begun to turn pale.

Li Changan took a full view of everyone's situation and quietly removed the killing intent at the eyebrows of several of them.

The students who had no killing intent immediately breathed a sigh of relief, and looked at Li Changan with palpitations.

He didn't dare to say a word, and even the sound of his breathing was unconsciously lightened, and he didn't dare to make any movement, for fear of attracting Li Changan's attention again.

Time passed little by little, and there were more and more Bailu students who couldn't support it, but there were still a few who still gritted their teeth and stood firm.

Especially Zhang Shaobai and Gu Qiuyan, both of them were already sweating profusely, and their cheeks were trembling, but they were stunned and stood motionless.

Li Chang'an raised his eyebrows slightly, and the dragon elephant breathed deeply, and the rotation speed of the killing intent arrow accelerated a little.

The fierce killing intent rose again.

The fear in Zhang Shaobai and Gu Qiuyan's eyes suddenly exploded, and their minds were about to be destroyed in an instant.

Li Changan immediately withdrew his killing intent, leaving only Zhang Shaobai and Gu Qiuyan gasping for breath as if they were drowning.

In the huge school, only the wheezing sound of the two was heard.

But no one laughed at them, and they were able to hold on for so long, far surpassing other students.

After everyone recovered from the killing intent, Li Changan said leisurely, "Today, I will first explain to you what multiplication is. ”

"Guan Sheng" has clouds: An drama is the number of ninety-nine to respond to the way of heaven. This number of ninety-nine is multiplication. ”

"You must be quite familiar with this, but for today's homework, I will make a slight adjustment on the basis of the "Sutra of Calculations".

"First of all, for the convenience of the future, I will use the multiplication × to represent ......"

Half an hour later,

When all the students were dizzy and about to collapse, Li Changan finally stopped teaching, "Today we mainly talked about multiplication. ”

"But at the same time, the four arithmetic methods have been sorted out, and I hope you will study more when you go back."

Zhang Shaobai and Gu Qiuyan glanced at each other, and they both saw despair in each other's eyes.

What the hell is this special?

Obviously, you can understand every word, but when you put it together, it makes people confused?

The four arithmetic operations can still be understood.

Where did those strange symbols come from? It's a head-scratcher.

Where did this Li Changan learn so many strange things?

"Today's homework is very simple, everyone writes a multiplication problem, and I'll check it tomorrow."

After Li Changan finished speaking, he left the school.

The school was suddenly full of mourning.

"God, how could Li Changan have so many strange things?"

"Hell in four calculations!"

"Plus, minus, multiplication, division...... Who created it? Why has it never been seen before? ”

"I have a foreboding feeling that the math class will become a haunting nightmare in the future...... I want to die! ”

"Don't be in a hurry to die, Li Changan said that there is homework today, otherwise tomorrow we will definitely torture us with killing intent as to die!"

As soon as they heard the killing intent, everyone present couldn't help but shudder.

Tete's grievance.

Lu's edict was harsh at best, and he never used force.

But Li Changan is good, and when he comes up, he is sharpened by the killing intent of a stick of incense, who can afford this?

"Brother Zhang, what should we do in the future?" Someone asked Zhang Shaobai, who clenched his fists.

Zhang Shaobai gritted his teeth and said, "I'm on the same page with him Li Changan!" ”

"Isn't it killing intent? Lao Tzu thinks this is a martial arts class! ”

"One day, I want to make Li Chang'an have nothing to teach, so I can only run away in disgrace!"

Gu Qiuyan also slapped the table, and said hatefully, "Yes, you can't let him be so arrogant anymore." ”

"Although the grinding of killing intent is painful, as long as you persevere, there will definitely be benefits!"

"Where can we find people who help us cultivate with their own killing intent on weekdays?"

"Li Changan thought he was intimidating us, but in fact it has become a stepping stone for our cultivation!"

"And this strange number of spells must have only been used to deter us at the beginning, and there can't be too many."

"Brother Zhang was right just now, soon he will be unteachable!"

……

Li Changan came to the back mountain of Zhushan, and he still had a smile on his face.

No wonder some people like to be teachers, it turns out that it is such a cool thing to transfer the pain of their own year to others.

It's just four operations in elementary school, and these guys can't stand it.

Later unary equations, binary systems of equations, unary quadratic equations......

Hey, just thinking about it makes me feel ...... So happy!

"Why is there no bitterness and hatred today?" Wang Tiangang asked with interest.

Li Changan smiled, "Senior, I seem to have found another way to cultivate killing intent." ”

"Tell me about it."

Li Changan told him about today's events.

Wang Tiangang was also happy when he heard it, "So these students have become your tools for cultivating killing intent?" ”

"This multi-purpose method can indeed improve the control of killing intent, and it is very beneficial, but be careful, don't cripple people."

"Once the mind is destroyed, that person will become a living dead for the rest of his life."

Li Changan nodded and said, "Senior, don't worry, I have tried many times myself, and there is no problem in sticking to a stick of incense at present." ”

"With so many people as targets, the speed of improvement will be very fast, and I believe that sticking to two sticks of incense will not be too far even a quarter of an hour."
