"The four operations, they are the collective name of the four basic operations of addition, subtraction, multiplication and division, most of you have learned multiplication now, if you want to break through the cultivation of the fourth grade, you will inevitably come into contact with the inverse operation of multiplication......"

Teacher Ding was giving a lecture on the stage, but Li Jun below was restless again because of the poison caused by Bo Li.

The itch, and the strange itch, was like a hole in the buttocks, and then the ants crawled out of it, struggling out of the flesh, fiddling and getting out. Itchy, and a little painful, this very strange itch then crawled out with the ants one by one, and then crawled out at random on the body, and soon, Li Jun felt that the places they had crawled over were all itchy with this kind of itch.

Then, the most terrible thing at this moment was that Li Jun couldn't scratch it at all.

In this public, in Teacher Ding's class, Li Jun didn't have the cheekiness to directly scratch his buttocks and tickle himself.

Some people say that cutting with a thousand knives is the most painful thing in the world, but now Li Jun doesn't think so, he thinks that the most painful thing in the world is itchy, and he can't scratch it at all.

However, it's really itchy!

So, under such a strange itch, although Li Jun didn't have that face to scratch, in order to stop the itch, Li Jun couldn't help but move his buttocks in a small range. Then, although this movement had a little effect, the itch stopped a little. But because of the movement, Li Jun felt an inexplicable pain again, and such a painful and itchy feeling was intertwined at once, which not only made Li Jun decide to be happy, but also made him feel extremely humiliated.

"Small! Ming!" Li Jun gritted his teeth and clenched his fists tightly, which not only stopped the itchy pain from his body, but also deepened Li Jun's resentment towards Xiao Ming wave after wave. In Li Jun's eyes, there was already a trace of resentment like substance.

If Li Jun still had a trace of pity for Xiao Ming before, he was ready to let him go when he taught Xiao Ming a lesson, and he would not be so heavy. But at this time, Li Jun is going to be with Xiao Ming no matter what!

"Brother Jun, what's the matter...... What's wrong?"

Li Jun's strangeness finally attracted the attention of Zhou Fei next to him.

"I didn't ...... No, it's okay!" And Li Jun, his face was red now, but he still waved his hand forcibly, shook his head, and signaled that he was fine. Even if Zhou Fei was Li Jun's close follower, Li Jun was embarrassed to tell Zhou Fei. Moreover, if Zhou Fei was told in such a secret place, wouldn't the majesty of his boss be dealt a major blow.

"Jun, Brother Jun, really, is it really okay? You, your face is very ugly?" But Zhou Fei is not blind, now sitting so close to Li Jun, he can naturally feel Li Jun's mouth, as if he is holding his breath, he can't help but ask again.

"It's okay! I said it's okay, it's okay, shut up for me!" Zhou Fei became such a mother-in-law, at this moment, Li Jun was in a bad health and mood, and he couldn't help but yell at Zhou Fei all of a sudden. This Zhou Fei made Li Jun look very unhappy today, if he wasn't still in class now, Li Jun really wanted to kick Zhou Fei directly.

"This multiplication—"

However, at this moment, although Li Jun tried his best to hold back, this roar was not small, and it suddenly interrupted Teacher Ding's lecture. The whole class, including Xiao Ming, looked at it at once.

"Forehead ......"

Li Jun immediately realized that he was afraid that he had made another mistake, his body stiffened, and his face suddenly remained in a state of yelling at Zhou Fei, not daring to look at Teacher Ding.

"Li Jun, Zhou Fei, what are you two doing? Stand up for me!"

Sure enough, when Teacher Ding saw that it was Li Jun and these two people again, he directly angrily told the two to stand up.

"You!"

At this moment, hearing Teacher Ding's anger, Li Jun immediately glanced at Zhou Fei viciously, and then drooped his head and stood up honestly.

Zhou Fei was angry by Li Jun and Teacher Ding, and then he felt a chill behind his back, and he also drooped his head and stood up, and at this moment, Zhou Fei also felt aggrieved and inexplicable. Doesn't he just care about Brother Jun? Why did Brother Jun suddenly get angry?

"You two stand up for me!" Seeing that the two of them stood up honestly, Mr. Ding's anger subsided temporarily, but seeing that both of them were drooping their heads, looking like they were not standing, Mr. Ding couldn't help but say a word. And the two of them immediately stood respectfully, not daring to say another word.

At this time, Mr. Ding was immediately satisfied.

"Keep going to class!"

Then Teacher Ding continued to teach again, and Xiao Ming's attention immediately turned to Teacher Ding. Mr. Ding's lectures are very good, the foundation is very solid, although Xiao Ming has Chen Lao, but Chen Lao only gives guidance in the general direction. And Xiao Ming sometimes doesn't want to ask Chen Lao if he asks too basic questions, for fear that Chen Lao will show contempt again. After all, Chen Lao is a mysterious master in Xiao Ming's heart, and it is impossible to ask Chen Lao any questions, even the most basic questions. Not only did that seem to be useless, but it also made Chen Lao's identity cheap.

Therefore, since he was in the third grade, Xiao Ming has been listening to the lectures as seriously as ever, especially the basic theoretical knowledge part, but Mr. Ding's own perception is very useful.

However, although Mr. Ding's lecture was good, Li Jun still had no desire to listen to the class at this moment. It's better to sit just now, at least I can rub it with pain and itching. But now that he was on his feet, he had nothing to rub against at all. And it seems that because he stood up, the blood circulation was a little faster, and the speed of the itchy pain just now spread much faster, and Li Jun felt the itch spreading all over his body almost immediately.

"Click!"

As a last resort, in such a state, Li Jun couldn't scratch anymore, his head was lowered and lowered, he could only grasp the table in front of him with both hands, and endure wave after wave of itching, hoping to relieve the symptoms of itching a little with the help of the power of grabbing the table.

"Brother Jun...... You ......" Zhou Fei next to him suddenly saw Li Jun's strange appearance again. It's just that as soon as he spoke, Li Jun next to him gave him a vicious look, which immediately made Zhou Fei close his mouth all of a sudden.

"Click......" But closing his mouth, Zhou Fei saw Li Jun's hands clutching the table again, and made a sound again, and looking at Li Jun's hard appearance, it seemed that his nails were going to sink deep into the table. Zhou Fei couldn't help but have a question in his heart, what happened to Brother Jun?

However, the current Zhou Fei didn't dare to say more, so he could only look at Li Jun carefully.

However, then, in less than two minutes, Li Jun seemed to be enduring some great pain, his hand that grabbed the table, forced, forced, and then the wood on the table, as if it couldn't stand the force, and the click actually began to slowly crack.

"Brother Jun......" Seeing this, Zhou Fei couldn't help but sweat for Li Jun, and at the same time he looked at Teacher Ding again.

"It's like you're familiar with the multiplication formula, just like this, five-five-twenty-five, it's reversed, twenty-five divided by five is division, but although division is the inverse of multiplication, the rules in it are subtle, it depends on you to come to understand......"

Teacher Ding was still teaching by himself, although Li Jun and Zhou Fei were standing, but Teacher Ding directly ignored the two.

"Click......"

Zhou Fei couldn't help but look back, and saw Li Junna enduring the pain again, his fingers had already pressed the mark on the table, and the increasingly powerful force had made the cracks on the table bigger and bigger.

"Don't!"

Finally, under Zhou Fei's gaze, the wooden board that made up the table didn't seem to be able to withstand so much force at all, and it was in disrepair, just being pinched twice by Li Jun, the sound of clicking came out immediately, and the crack just now expanded at a speed visible to the naked eye, and the crack soon spread to the entire desktop.

"Whoa!"

"Puff ......"

Yes~

The next moment, the wooden board of the table was directly crushed into pieces by Li Jun's strong force, and due to the instant loss of support, Li Jun fell backwards all of a sudden, and then hit the table of the girl at the back table, and the female classmate was frightened and screamed out at once.

This......

Zhou Fei only had time to stretch out his hand to stop it, but he didn't expect this scene to break out in an instant, he immediately froze in place, and then looked at Teacher Ding worriedly. If the situation is out again, and it's them again, this Teacher Ding will definitely break out.

"You guys!"

"Li Jun, Zhou Fei, you, get out of the classroom for me!"

Then, sure enough, Teacher Ding was interrupted from his lecture again in an instant, and suddenly saw that it was Li Jun and Zhou Fei again, and Teacher Ding pointed at the two angrily and directly asked the two to get out of the classroom.

"Teacher ......"

At this moment, Li Jun also came back to his senses, and then glanced at Teacher Ding, and then before he could express anything, another series of strange itches came.

"Let's go!"

Before he had time to say anything, Li Jun walked out of his position directly, and then Zhou Fei and Li Jun, under the angry gaze of Teacher Ding, ran out of the classroom in a gloomy manner.

"What's wrong with them?"

The successive abnormalities directly aroused Xiao Ming's curiosity, and Li Jun ran out and glared at Xiao Ming again, which made Xiao Ming feel even more inexplicable.

"Who knows, maybe you've gone mad...... However, what does it matter to us......" Xiaohua pursed his lips and said unconcernedly.

"Alright, let's move on. And Teacher Ding, seeing Li Jun and them rushing out so quickly, was also a little puzzled, but the doubts flashed for a moment, and then looked at the classmates paying attention to him, he waved his hand, and then continued the class. Li Jun has already annoyed him, and now it is better to be out of sight.

"Subtraction is a special addition, division is a special multiplication......"

Listening to Teacher Ding's class, although Xiao Ming still had some doubts in his heart, he continued to listen to Teacher Ding's lecture after Teacher Ding spoke.

As Xiaohua said, it is indeed none of their business, and what Li Jun is like has nothing to do with them.

However, this is what Xiao Ming thinks for themselves, Li Jun, who rushed out of the classroom at this moment, is free all of a sudden!

"Xiao Ming, you wait, Xiao Ming, you wait for me!" After rushing out of the classroom, Li Jun gritted his teeth and said Xiao Ming's name while looking for a hidden location. Then he found the direction of the grove, and ran over quickly, he really couldn't stand this strange itch, it was so uncomfortable, now he had to find a hidden place quickly, and see what was going on with his ass. And the grove is undoubtedly the best choice.

"Brother Jun, what's wrong with you?"

Zhou Fei, who came out, immediately saw Li Jun's panicked appearance, shouted, and quickly followed.

"Finally can't help it?" hehe......" After the two left, Bo Li appeared immediately, seeing Li Jun's anxious appearance, Bo Li immediately knew the reason why Li Jun was anxious, smiled, and a bottle of green liquid immediately appeared in his hand.

"Okay, for Xiao Ming's sake, I'll help you relieve your pain. After talking to himself, Bo Li put away the antidote in his hand, and then slowly followed the two.
