Late at night.

One family rejoices and one sorrows.

After eating from Lao Cao.

Cao Yu went straight back to his mansion.

Packing up the luggage in the room and looking at the moon outside the window.

"O the moon! Moon! In the future, we will have to change places to appreciate your beauty! ”

After speaking, Cao Yu began to load his daily necessities again.

What faucet, hot pot......

Pack them all.

This is to the poor countryside of Wancheng, but it is all of great use.

And in the Xiahoudun mansion in the south of the city.

Cao Zhang's first entry into the barracks.

So I'm here to visit tonight.

Also accompanying him was Cao Pi.

It's all people from the same camp.

That's why everyone is talking about wine.

And yet at this moment.

The sound of a butler announcing the news broke their laughter.

"What? You said that Cao Yu's kid went to Taixue in the morning? Cao Pi's shrill voice immediately penetrated the room.

Xiahoudun and Xiahouba were also shocked.

They all thought that Cao Yu didn't dare to go to Taixue Mansion.

It's because I know that I'm bragging and I'm going to drag it back.

But I didn't expect a big reversal today.

All were shocked.

Only Cao Zhang, who didn't know why, looked confused.

What is too much of an institution?

What nine chapters of arithmetic?

And the sixth Cao Yu is not that concubine?

Why does the second brother seem to care about him very much.

The butler continued.

The more Cao Pi listened, the more frightened they became.

The more I listened, the more shocked I became!

it!

God doesn't need to kill Sima Fu in seconds.

God's Arabic numerals.

God's multiplication formula.

If it weren't for Cao Pi, he wouldn't have drunk much tonight.

You should think you're drunk.

Listened to a ghost story.

And Xiahoudun next to him was also shocked when he heard this, and his mouth was almost ready to stuff two eggs.

After reacting, he quickly took a sip of wine to suppress the shock.

Is this really the fool and madman rumored out there?

The idea of this meow is really crazy.

But we must treat each other as harmless fools.

Then you are the biggest fool.

Xiahoudun squinted slightly, looking at the moonlight outside the window.

Secretly Cao Yu's scheming is deep in the city.

Then he looked at Cao Pi opposite, and a strong worry appeared on his face.

Now the title of the heir is imminent.

As a result, he made such a trip to bite the gold halfway.

Hearing this, Cao Zhang, who was next to him, also understood.

"Harm! I thought you were talking about something! Isn't it just a concubine! How can everyone be like the enemy at present! Cao Zhang's face was full of disdain.

It's just a concubine!

No matter how powerful it is, it's a concubine!

"Big brother, Cao Yu is not a fool! Is this nine-chapter arithmetic method really him? Xiahou Ba's head was not so bright, and he still hadn't figured it out, so he touched the back of his head and said quietly.

Just as Xiahoudun was about to explain, Cao Pi's voice was the first to interrupt.

At the same time, he also looked solemnly at Cao Zhangna.

"Cao Yu, we all underestimated him before, and the world said that he was crazy and stupid, I'm afraid he pretended to be!"

Cao Pi clenched the wine glass with his right hand and tightened it for a few more minutes, and then leaned back.

"Have you ever seen such a fool who can study the traffic?"

Xiahou Ba hurriedly shook his head.

If a fool can study it, then he is not even as good as a fool.

Although Cao Zhang, who looked disdainful next to him, had to admit the facts.

"Have you ever seen a fool so proficient in mathematics?"

Xiahou Ba hurriedly shook his head again.

Cao Zhang's expression was still calm.

But knowing that Cao Pi said the next sentence.

Cao Zhang was not calm at all.

"My father is like a god with soldiers, and his eyes are like torches, you can see that he is very good!"

"And these days, my father goes to his mansion every day!"

Cao Pi's last faint voice was like a demonic voice.

Cao Zhang, who was originally disdainful, immediately became shocked.

"What...... Second brother, you said that my father went to his mansion every day these days, and also gave him to serve as a doctor of Taixue Mansion and a general of Zhenfu one after another? ”

Hearing this, Cao Zhang's voice sharpened a little.

Because I just joined the army these days, there are too many detritum things, and I don't care about the outside world.

But I didn't expect it to be less than five days.

The outside world almost became unrecognizable to him.

Especially when I heard that Cao Yu's official position in the army was still one level older than him.

His heart felt as if he had just a hundred lemons in his heart.

"Father is partial, why was he Cao Yu named General Zhenfu!" Cao Zhang remembered that since the concubine he despised before was his superior, his heart felt like a fly.

"The fourth child said cautiously, it's okay to be your own person here, don't say this again!" Cao Pi immediately shouted.

Cao Zhang realized that he had just lost his words, and if this word reached his father's ears, I am afraid that punishment would be indispensable.

While his back was cold, Cao Zhang was also forced to face up to Cao Yu's threat.

A drink was drunk late into the night.

Just when the show was about to end.

A loud trumpet sounded.

"Prince Cao Zhang, the lord invites you to the Prime Minister's Mansion!"

As soon as this remark came out.

was so frightened that Cao Zhangs back was a chill.

Cold sweat broke out on his forehead.

The six gods looked at Cao Pi next to him.

I thought that my gaffe just now had reached Lao Cao's ears.

In the blink of an eye, I saw a burly man in a green hat with a knife at his waist.

"Xu Chu will ...... Checkmate! I wonder what happened to my father's summons? Cao Zhang stumbled and asked.

"I don't know about the lord's affairs, but I'll find out when you go!"

……

And at the same time.

Yang Biao's house.

Kong Rong, Dong Cheng and others were invited to discuss major matters together.

I heard that Cao Yu Bairi Taixue was shining.

Everyone was shocked.

"How is this possible? The speed without an abacus is faster than that of Sima Fu with an abacus? The old antique Kong Rong immediately shook his head and said that he didn't believe it when he was killed.

Yang Biao and Dong Cheng on the main seat were also shocked, and then they were suspicious.

These nine chapters of arithmetic are too much for them to realize.

But absolutely, Yang Biao and his son will not joke about this.

"Uncle Kong Rong is real, although I was not present at the time, my classmate was there, he would not lie to me about this matter!" Yang Xiu arched his hand and said seriously.

"And I also deliberately studied the addition formula table in the nine chapters of arithmetic he talked about during the day, and found that it is indeed possible to do without an abacus, and I don't believe that my uncle can have a fight with me!"

"Xiu'er must not mess around! How could anyone talk to the descendants of Confucius like this! Yang Biao immediately put down the teacup in his hand and scolded.

"It doesn't matter! Anyway! The ancestors have a cloud: whether it is a mule or a horse that comes out to slip away, why don't we have a competition! Kong Rong touched his mustache and said with a hypocritical expression.

Regarding what Cao Yu said about bullshit nine chapters of arithmetic, he didn't believe it anyway.

What bullshit three days makes people proficient in arithmetic.

What bullshit is faster than an abacus without an abacus!

Too!

However, the thought did not last two minutes.

When he saw that Yang Xiu really couldn't quickly answer the answer to the question he wrote without using an abacus.

People are completely stupid!

Even Kong Rong was a little unwilling.

I thought the other party was a blind cat and a dead mouse.

A few more questions.

The results were all correct.

Kong Rong's people were completely cracked.

Compared to the bull just now, the bull is angry.

In this second, it becomes a frosted eggplant.

Especially when I think of the nonsense I made in the court before.

said that if Cao Yu's nine-chapter arithmetic could make the old and young women and children proficient in three days, he would eat.

Thinking of this, the smell of Kong Rong was a little tumbling.

Everyone didn't pay attention to Kong Rong's abnormality, but all paid attention to Yang Xiu.

"Xiuwei, this addition formula table, multiplication formula table is really so simple?" Yang Biao didn't care about the majesty of being a father, and immediately asked.

"Back to my father's words, the addition formula table and the multiplication formula table are indeed as long as you memorize him, you can immediately master mathematics." Yang Xiu nodded affirmatively, but then there was a blush on his face.

"The child is ashamed, although he knows the addition and subtraction formula table and the multiplication formula table, the child can't see through the reason!"

Well!??

Hearing Yang Xiu's words, Yang Biao's face was shocked again.

His son Yang Xiu's cleverness, he knows best.

But even his son couldn't understand it.

What a profound wisdom is contained in this formula of addition, subtraction, multiplication and division.

Hiss......

Thinking of this, Yang Biao also gasped.

Suddenly came to mind that day.

The only thing I've ever seen is a guy who is a little weak and looks harmless.

Combined with the facts of these days, he thought of something even more terrifying.

Cao Yu has been pretending to be crazy and stupid!

Hiss!!!

If that's the case, then how deep should this kid's city and scheming be!

That's obviously a kid who hasn't been crowned yet!

but deceived the people of the world in the palm of his hand.

Yang Biao looked at his son again, and immediately shook his head and sighed secretly.

Far from it! What a difference!

"Xiu'er, go back to the room first, I have important things to discuss with your uncles!"
