Chapter 9 Arithmetic?

As soon as this remark came out.

The classroom fell silent again.

Everyone looked at each other.

You look at me, and I look at you.

There was confusion in his eyes.

At this time, a few sharp points that had been impatient for a long time immediately rushed out.

"Teacher Cao, what is the nine chapters of arithmetic! It won't teach us to plan the plate! ”

"Yes, we are all people who want to do big things in the future, let's not do it, Mr. Accounting!"

"Alas! Don't say that, two brothers! Confucius Youyun: Take the essence and remove the dross! ”

The three of them sang and performed in harmony.

Cao Yu watched quietly from the podium.

The little black man shows his chicken feet!

And the audience next to them also showed doubts.

Could it be that he really dials such a small ear as an abacus?

"Everyone, be still! Listen to my eldest brother Cao Yu! At this time, the little fat man from earlier immediately rushed out and yelled.

The big round body and the loud enough voice really scared everyone for a while.

Cao Yu looked at the little fat man in front of him with some curiosity.

"Big brother, I'm Cao Zhen, the prime minister's righteous son!" Cao Zhen showed a courteous expression and gestured towards Cao Yu.

It turned out to be him, and later he was in charge of the Tiger and Par Battalion and had great achievements, but he was also a fierce man. after

Cao Yu's face was slightly startled, and then he was relieved.

At this time, Cao Zhen was still young and did not show military talent.

My father also died early, and there is no background in the family.

Being excluded by everyone is really a bit of a hard time to say.

If so, there is a reason to show favor to yourself.

After sorting out the logic, Cao Yu nodded at the other party to show that he returned the salute.

"Ahem, ahem, ahem......"

"The three brothers just now said that the nine-chapter arithmetic is the method of abacus, which is not entirely right."

As soon as the voice came out.

The person who had mocked before immediately showed a sneering expression, thinking that Cao Yu was poor and the donkey was poor.

"Then I don't know Mr. Cao, what's wrong?" Sure enough, the mustache headed by him immediately deliberately made things difficult.

"Huh!" Cao Yu looked at the gloating expression, and there was a sneer.

"Under the nine chapters of arithmetic, it can be regarded as fried rice, oil and salt!"

"Cut! I thought it was nothing, isn't this just an abacus! The mustache sarcastically said on the spot.

"I thought you could figure out the sky!"

However, the mustache has not finished speaking.

In the next second, Cao Yu's words stunned him.

"Nine chapters of arithmetic!"

"It can be counted as firewood, rice, oil and salt!"

"It's the right time and place!"

I only heard Cao Yu's sick voice coming out.

But this voice shook everyone's hearts!

Like a bell, it can't be dissipated for a long time.

Cao Cao, who had just arrived at the gate of Taixue, also happened to hear it.

"Lord, do you need to help you move a chair?" Xu Chu next to him asked.

"Shh Cao Cao put his finger to his mouth and couldn't help but get a few closer to the window.

The next can be counted as firewood, rice, oil and salt,

It can be regarded as the right time and place!

It's a big breath.

I'd like to hear what kind of algorithm you are.

Cao Cao stuck it in the corner, for fear of missing any detail.

Xu Chu next to him yawned, and there were two small stools in the classroom next door.

And at the moment.

There was another uproar in the classroom.

"Arrogance! Even Sage Kong said that people are not as good as heaven, and you little doctor is full of wild words! ”

The mustache immediately jumped to his feet and pointed at Cao Yu's nose.

"Do you think it's even more powerful than Sage Kong?"

As soon as this remark came out.

The whole classroom immediately became tense.

Although most of the people in the classroom are not advocating Confucianism.

But in this era, as long as anyone dares to question Confucius, it is like violating the rules of heaven.

Even these people can't avoid it.

"Hey! Mustache, you're here to make trouble! If you dare to talk nonsense again, beware of me pumping you! Although the little fat man Cao Zhen didn't know a few big characters, he still saw the bad intentions of the mustache.

"Hehe, what! Discuss academics, not yet allowed to question? Only one word is allowed? The mustache seemed to be prepared and not afraid at all.

didn't even think it was a big deal, and deliberately put his face in front of Cao Zhen provocatively.

It seems to say that there is a kind of you hitting me!

The little fat man Cao Zhen was so angry that his white face turned red for a while.

"You ......"

"Questioning? Hehe? Cao Yu secretly showed murderous aura.

He really said about Confucianism.

"Then ask rhetorically, what do you think about the comparison between Confucius Wuyong and Xiang Yu, the overlord of Chu?"

"How can this be compared......" The mustache immediately retorted.

"If you are debating, why don't you dare to answer it head-on!"

Cao Yu's domineering voice resounded in the classroom again.

Behind the mustache, I felt cold, and I felt oppressed by a male master.

"Yes...... It's Xiang Yu! The mustache wiped the sweat from his forehead, not daring not to answer.

"Then let me ask again, what about the invention of Luban and Confucius?" Cao Yu's eyes narrowed slightly, and he said coldly.

Goo-Du –

The mustache swallowed hard before he spoke.

"Yes...... Luban! ”

"On medical skills, what about Hua Tuo and Confucius?"

"Yes...... Hua Tuo! ”

"Since Confucius is not the same in martial arts, invention, and medicine!"

After saying this, Cao Yu suddenly stood up from his seat, slapped his palm on the table, and shouted.

"Then why do you think that arithmetic, I am not as good as Confucius?"

Thundered!!!

Thunder rang out.

The originally clear sky suddenly closed with dark clouds.

In the gloomy sky, a flash of lightning suddenly slashed.

Through the window.

I saw a blue light and shadow.

It's like a Tarzan top.

The eyes are full of strange colors.

Cao Cao outside the window was all shocked.

He couldn't have imagined it.

Such a weak body can exude such coercion.

What made him even more worried was that.

This kind of coercion only had the feeling of dragon power when he went to Luoyang with his father Cao Song to see Liu Hong, Emperor Ling of the Han Dynasty.

"Lord, it's dark this day, and it's going to rain in a while, so let's go in and listen!" Xu Chu yawned and sat in his chair.

"Go get an oil umbrella! You and I can stand by and listen! Cao Cao kicked Xu Chu angrily.

This guy, what to learn, what is not good, the first place in eating.

And the classroom is still quiet.

Everyone's pupils were slightly open, and their mouths were almost able to stuff an egg.

Even Cao Zhen, who wanted to show favor to Cao Yu, swallowed his saliva.

Eldest brother! I don't want you to play like this!

We are young and frivolous, and we are crazy!

You can't directly benchmark Confucius like this!

I'm afraid that what you just said will get out.

Those old lunatics who worship Confucianism haven't killed you alive!

Regardless of everyone's shock, Cao Yu continued.

"Cao Zhen, let me ask you, do you know why the Yellow Turban Rebellion was made in Jiazi Year?"

Cao Zhen: ???

"Foolish brother doesn't know! But the common people have nothing to eat, so they want to revolt? ”

Although he didn't know why he asked this question, Cao Zhen still tried his best to reply.

The rest of the people also gradually came back to their senses, and looked at Cao Yu with some curiosity.

As if hoping to get an answer.

"Not bad! This is the superficial cause, we need to see the essence through the phenomenon! Cao Yu's slight voice sounded again.

"Big brother, what do you mean by seeing the essence through the phenomenon!" Cao Zhen scratched the back of his head, a little embarrassed.

Cao Zhen thought that he was a little educated, lonely and unheard, and he had never heard of this word.

Actually, none of the people below have heard of it.

Even Cao Cao at the door was full of confusion.

"This ...... It means that through an event, the real cause of this incident can be discovered, and only in this way can the previous tragedy be avoided from happening again. Cao Yu remembered that this was a word for later generations, so he naturally explained patiently.

And Cao Cao, who was hiding behind the window and eavesdropping, heard this, and immediately slapped his thigh.

What a way to see the essence through the phenomenon!

Wu Cao must see the essence through the phenomenon and study the rise and fall of the dynasties of the past dynasties.

At the same time, he regretted Cao Yu a little.

You rabbit, how can you just pass on this kind of knowledge to others?

I want to rush into Taixue and drive everyone away, and listen to it alone.

But I'm worried that if I go in, this stinky boy will start to play tricks and pretend to be a rookie.

Suppressing the impulse in my heart, I decided to learn honestly outside.

"That big brother, looking at the essence through the phenomenon, if you want to avoid another Yellow Turban Uprising, you just want to let the people eat enough!" Cao Zhen's voice sounded again.

"Yes! But why don't the people have enough to eat? Cao Yu nodded and asked again.

"This ...... The foolish brother doesn't know! Cao Zhen scratched his head, he naturally didn't understand the hardships of farming and mulberry when he lived in the army.

At this moment, a piercing voice sounded.

"Cut! Those mud-legged people can't afford to eat, and they're not too lazy to eat! The mustache immediately disdained.

The group next to him couldn't help but say.

"That is, if they were a little more diligent, they would not let the treasury run empty every day."

"Such people should starve to death!"

The more the words are spoken, the more excessive.

The rest of the people were furious.

These few people who have no worries about food and clothing every day, drink and write poetry at home, have never seen Tian Sang.

But the rest of the people are mostly ordinary people who are not even from a poor family.

But I have experienced the hardships of farming.

This kind of saying that you don't eat meat porridge, Cao Yu also had a sudden burst of temples.

If it weren't for the fact that I wanted to keep the character of the sick seedling, I would like to slap these three pieces of shit to death now.

"I also said before that the method of arithmetic in the nine chapters can be regarded as the right time and place!"

"Do you remember!"

Everyone nodded.

Could it be that these nine chapters of arithmetic can deduce the Yellow Turban Uprising?

"Yes, I think everyone has guessed that the nine chapters of arithmetic can indeed be deduced!" Cao Yu's sickly voice once again stirred up a thousand waves.

What?

How is this possible?

If only the nine-chapter arithmetic could deduce the future.

You're an arithmetic, you're obviously a fortune teller!

All of them looked skeptical.

After all, this kind of technique of measuring the heavenly machine was done by those Taoist priests.

"Don't worry, everyone, and listen to me slowly put aside the phenomenon and see the essence!" Cao Yu slapped the podium.

Syllable!!!

Make a crisp sound.

"Why is it that with such a low tax of thirty taxes, it is difficult for the people to live!"

The tax on the total income of the peasants was one-thirtieth of the tax, which was also a very low tax in the past dynasties.

Everyone stared at the podium with confused eyes.

Cao Cao outside the window was even more energetic, and his breathing was a little short.
