Prime Minister's Office.

In the study.

I only heard a series of shocking voices.

"What? Arabic numeral? ”

"What? As long as you memorize the addition and subtraction formula, you can calculate the answer in one second! ”

"What? There is also a multiplication formula table! ”

Heard Cao Cao just said a few unheard of things.

Rao is usually as stable as Mount Tai, and Xun Yu is not calm.

"My lord, what are these Arabic numerals? Is it really that amazing? ”

"Yes! Don't let others fool you, where in the world do you have this kind of skill. Xun You also touched his chin, his eyes full of disbelief.

Even Guo Jia didn't help the lord speak this time.

Looking at this group of people, no one believed it, Cao Cao showed a wicked smile and thought about it.

"Ahem, ahem...... Since you don't believe it, why don't we make a bet? ”

"What bet?"

"If everything I just said is true, Guo Jia, you will quit drinking for a month! The rest of the people danced in the streets! ”

When Guo Jia heard that he was going to quit drinking for a month, his eyes immediately showed a look of vigilance.

If he loses for a month and doesn't drink alcohol, it won't kill him.

"If you win, I'll reward you with a few jars of peerless wine, and make sure you never drank it!" Cao Cao suddenly remembered the fine wine he had drunk last time he went to Cao Yu, and he suddenly lingered a little.

Seeing Guo Jiana's vigilant appearance, he knew what the other party was thinking, and immediately threw down the bait.

"Haven't drunk a good wine? Is the lord serious? Guo Jia touched the back of his head and said a little greedily.

"Nature is more real than gold!" Cao Cao smiled, but said secretly in his heart.

If you win, you have to win.

"Then it's a gamble!" Guo Jia immediately agreed.

He couldn't bear the child and couldn't trap the wolf, so he fought for the wine.

And Xun Yu and Xun Yu felt tired, no matter how Cao Cao instigated them, they just didn't get on the road.

Cao Cao had no choice but to give up.

"Ahem, that's what this Arabic numeral is!"

Cao Cao explained, usually writing out a few crooked numbers by hand.

Xun Yu and Xun Yu were full of curiosity.

What does this number have to do with the next arithmetic?

And Guo Jia was smiling in his heart.

It's absolutely impossible to win with this broken number.

At the same time, I fantasized about a while of wine.

It can be receded over time.

When Lao Cao talked about the addition and subtraction formula.

Guo Jia's face was trembling.

Especially when I saw Cao Cao's straightforward calculation of some account book numbers without dialing the abacus.

I feel bad.

But then he calmed down a little.

Even if these nine chapters of arithmetic cows.

And just for some simple arithmetic.

If it's a little more complicated, it won't work right away.

However, the next second.

When Cao Cao began to put the multiplication formula table.

I saw a complex string of ledger numbers that couldn't have been more complicated.

It's also when the answer will be worked out in a moment.

Guo Jia completely stopped in Bengbu.

it!

I can do it too!

Lie.

Guo Jia, who didn't believe in evil, thought that Cao Cao knew the answer in advance.

So he picked a few again for Cao Cao to count.

But in the end, the result was unanimous.

Guo Jia completely collapsed.

Tears almost burst into my eyes.

It's not about wine anymore.

That's a month of abstinence.

Routine! It's all a routine!

"Hey, hey! Filial piety for a month! Cao Cao smiled brightly.

Then Guo Jia's tears were about to squeeze out, and he was embarrassed to squeeze out a smile that was more ugly than crying.

The man spat and nailed.

Can you still play tricks with the lord?

And Xun Yu and Xun Yu next to him were also shocked.

They didn't even think of it.

With these Arabic numerals.

Arithmetic has never been easier.

Xun Yu then rejoiced.

With this method, you don't have to worry about the people below making fake accounts in the future.

Then looked at Guo Jia's resentful eyes, and was glad that he was not involved in the bet just now.

"The great wisdom of the Lord is beyond my reach, and I can come up with such a wonderful method! Subordinates admire and admire! ”

Xun You recovered from the shock and immediately sent a blow to the horse.

"Lord, wise, I'm afraid that the method of arithmetic in these nine chapters will need to be recorded in history and passed down through the ages!" Guo Jia also reacted at this moment, knowing how much benefit these nine chapters of arithmetic would bring.

However, the next second.

I only heard Cao Cao's hearty laughter.

"Hahaha! I can't think of that! ”

As soon as this remark came out.

Everyone's breath was holding their breath.

In particular, Xun Yu is looking forward to it with satisfaction.

Last time, I felt that there was a master behind the lord.

I'll just say it!

The lord is able to come up with people like fighting to raise war, persuading Zhang Xiu, and nine chapters of arithmetic!

Come out!

Behind the master.

Just when Xun Yu, Xun Yu, and Guo Jia were looking forward to hearing the name of the master.

The next second it was stupid.

"All of this was thought up by my unassuming old six!"

Although it was said that he was not angry, Cao Cao did not see a trace of embarrassment on his face, but was very proud.

But this proud expression fell into Xun You's eyes.

The brain makes up for the other.

Is he the master behind the scenes?

How can it be?

Hehe! You're going to fool us!

This series of strategies and wisdom was thought up by Cao Yu's kid?

When pigs fly!

Guo Jia also looked at Cao Cao with disdain.

Even if you want to divert the hatred of quitting drinking, find someone I can trust.

And Xun Yu and Xun Yu didn't have any expressions.

But the heart is also speechless.

Lord, let's just say, don't pretend.

Let's have a showdown!

For everyone's strange expressions, Cao Cao thought that the news was too shocking.

So everyone needs time to absorb for a while, and they don't have to be suspicious.

"How is the crusade against Yuan Shu issued last time!" Cao Cao asked.

"Lord, your crusade against Yuan Shu has been issued! Now only Sun Ce corresponds to us! Speaking of business, Xun Yu immediately returned to the right color.

"Hmmm! It's not unexpected, Sun Ce has long been eyeing Shouchun, and it's normal for the rest of the people to not move! ”

Cao Cao stroked his hair and nodded secretly, his fingers lightly tapping on the table.

Originally, because he wanted to crusade against Zhang Xiu, he didn't plan to do it to Yuan Shu so early.

After all, the troops are not enough, but now they can persuade Zhang Xiu to surrender without spending a single soldier.

Naturally, he could free up his hands to clean up Yuan Shu.

"For now, I just have to wait for news from Cheng Yu!"

"My lord! Cheng Yu asks to see! ”

At this moment, Xu Chu's loudspeaker suddenly sounded outside the door.

Hearing the news, Cao Cao immediately bounced up from his seat, and he didn't even have time to put on his shoes.

"Hurry up, please!" Cao Cao walked out of the study barefoot.

Seeing Cheng Yu's dusty appearance, he immediately took Cheng Yu's hand.

"Cheng Yu has worked hard all the way, and he has lost weight!"

"Cheng Yu is fortunate to do things for the main business." Cheng Yu looked at the appearance of the lord's bare feet, and immediately burst into gratitude.

After a few words of greeting, Cao Cao was a little impatient.

Whether Zhang Xiu successfully surrendered or not is related to whether he can use troops against Yuan Shu next.

And in the last dream, because Cao Pi died, he died too quickly.

He also didn't know the result of Zhang Xiu's surrender.

Although he now has a blind trust in Cao Yu.

But when it comes to the real reveal.

Still nervous.

"Weichen is not doing well, please surrender the lord!"

As soon as these words came out, Cao Cao, who had already raised his throat in his heart.

My heart suddenly chuckled.

How so?

It wasn't Cao Yuti's persuasion to surrender Zhang Xiu.

How could it fail?

"Cheng Yu, let's get up and talk slowly!" Although Cao Cao felt uncomfortable, he still helped Cheng Yu.

"This time the envoy went to Wancheng, and his subordinates also made a special investigation and found that the entire city was full of death."

"There were hardly any business people on the streets, and even many of the officers had fled."

Cheng Yu told Wancheng what he saw and heard one by one.

Xun Yu next to him frowned slightly when he heard this.

"The people's hearts have been lost, and their morale has been completely lost, isn't it even more important to surrender?"

"yes?" Xun You also nodded, a little confused.

"The subordinates also thought that this negotiation must be nine out of ten, and Zhang Xiu would definitely surrender, but when he negotiated with him, he put forward so many conditions!"

"Oh! What are the conditions? When Cao Cao heard this, he immediately knew that the key was coming.
