"The lord is not good! Something is wrong! ”

At this time, a loudspeaker sounded in the prime minister's mansion.

A green figure shuttled quickly.

At this time, Lao Cao in the house was still eating breakfast slowly.

These few nights in order to simulate the brush experience upgrade.

During the day, it was for Cao Yu's affairs.

It's been a long time since I've even enjoyed breakfast.

Today, Cao Yu finally rested, and he just had a good time.

"Why is Zhongkang in such a hurry, is there news from Zhang Xiu?" Lao Cao took a sip of soy milk without slowness.

"It's not!" Xu Chu hurriedly denied.

"Oh! What's the big deal! Lao Cao is even less anxious now.

"Yes...... It's ......"

"Alas! Don't be in a hurry, sit down and drink some soy milk to moisten your throat! This is something I just grinded out. Cao Cao hurriedly pulled Xu Chu's shoulders and served him a bowl.

"There are also baked cakes to try, they taste good!"

When Xu Chu saw the prime minister like this, he thought he had gotten some news.

So I wasn't in such a hurry, but sat down to have breakfast.

It wasn't until a long time later that Lao Cao took a sip of soy milk and asked slowly.

"Zhongkang, what were you going to say just now?"

"Oh! It's nothing, it's just that the sixth son went to Taixue today! Xu Chu's mouth was stuffed with bread, and he muttered a little when he spoke.

But these words made Lao Cao hear it all.

A mouthful of soy milk squirts.

Poof-

"Ahem, ahem...... What did you just say? Cao Yu went to Taixue? Cao Cao choked on soy milk and patted his chest and coughed violently.

"That's right!" Xu Chu blinked, full of doubts.

Shouldn't you know this news?

"Confused! Zhongkang, you mistook me for a big deal! ”

Lao Cao was not calm at all, especially when he saw that Xu Fatzi wanted to drink soy milk with his mouth full of cakes, he couldn't wait to smoke him.

Although he didn't let him say it just now.

But it's such a big thing, how can you not say it.

We still plan to rely on these nine chapters of arithmetic to save our lives.

While muttering along the way, I also remembered the scene in my dream.

He clearly remembered that the scene simulated in the dream was that Cao Yu went to Taixue Mansion three days after he was at home.

That's why I dare to be so calm, and I plan to wait until three days later.

But why don't you play your cards according to the routine?

Could it be because he gave him a new position?

So changed the original trajectory?

This thought suddenly made Lao Cao have a new idea.

But there is no time to continue thinking.

Horseback with a long whip.

A quarter of an hour later, Lao Cao finally arrived at Taixuefu.

I didn't even have time to sort out my clothes, so I hurriedly ran to Cao Yu's classroom.

Fortunately, when I arrived at the door of the classroom, I was relieved that I didn't miss the key content.

Looking at the tiger idiot Xu Chu next to him, Lao Cao had a sudden burst of temples.

"Ahem, ahem...... That's right, I'm about to create a whole new world of mathematics! ”

Cao Yu's determined voice came from the classroom.

There was a sudden silence under the podium.

Then there was a sigh.

"Hahahaha!"

"Stop! Who do you think you are? And create a whole new world! ”

"Poof! Mr. Cao: Although I think some of your words are indeed very knowledgeable, isn't this too exaggerated! ”

"Teacher Cao doesn't pretend, we're still good friends!"

The people below were half silent and skeptical, half skeptical.

Just when it was said that some people were laughing at Cao Yu for not being optimistic.

Suddenly, a crisp and pleasant voice sounded.

"Cao Yu...... Teacher Cao, I'm optimistic about you! I believe in your nine chapters of arithmetic! ”

As soon as this sound came out, it was like a fire in the cold winter snowflakes.

Explode throughout the classroom.

Although the voice is not very loud, it is very firm.

Sun Shangxiang didn't know where the courage suddenly came.

She just didn't want to see so many people in the classroom, but no one wanted to believe him.

She didn't want to see Cao Yu standing alone on the podium.

But no one from the pulpit cheered him on.

How uncomfortable he must have been!

If all of them don't do it.

Leave this to me Xiangxiang!

We're good friends, aren't we?

Sun Shangxiang stood in the midst of everyone, clenching his fists resolutely, and shouted with his eyes closed.

"Teacher Cao! I believe you! ”

The crisp voice made Cao Yu slightly stunned, then smiled faintly and walked off the podium.

"It turned out to be Brother Sun! Thank you for your trust! Cao Yu patted Sun Shangxiang's shoulder affectionately like a good brother.

After all, he is his number one little fan, and he must be given the best treatment.

Suddenly, the scorching breath came in.

Sun Shangxiang only felt a burning sensation in his shoulders and back, and then opened his eyes to see Cao Yu's handsome and slightly sickly face.

Immediately, the head looked like a small steam engine.

When I rubbed it, it was red and steaming.

It was the first time she had been so close to a man.

"Brother Cao, I believe in you too!"

At this moment, Cao Zhen, who was not far away, also immediately raised his hand in support.

Although he can't understand math, he has to support the big brother wave.

"Good brother!" Cao Yu walked over and patted Cao Zhen on the shoulder again, and nodded.

Although there are only two people in the whole classroom who believe and support.

But Cao Yu was still quite happy in his heart.

After all, it's really nice to have someone who trusts you in a foreign country.

Meanwhile.

in the crowd.

Sima Fu's eyes narrowed slightly.

For the logical genius who is proficient in calculations, he has naturally also studied mathematics.

Although he has also done some things to improve the original mathematics.

But in his opinion, it is almost impossible to completely innovate.

"Cao Gongzi, there is something I want to ask below!" Sima Fu suddenly raised his hand and said.

The classroom, which had been a little warm, was quiet again.

Cao Yu also turned around.

Carefully looked at the questioner in front of him.

While he was looking, Sima Yi on the opposite side was also looking at each other.

Feeling the other party's eyes not to be outdone, Cao Yu's eyes were slightly shocked.

It's kind of interesting!

"I don't know what this brother wants to ask!" Cao Yu withdrew his eyes and bowed.

"I also have a little study of mathematics in Xiawen, and I have read the "Zhou Ji Sutra"!"

"The method of counting comes from the circle, the circle comes from the square, the square comes from the moment, and the moment comes from the ninety-nine-eighty-one. Therefore, the moment is broken, thinking that the sentence is wide three, the hook is four, and the passage is five. Even then, there could not have been such a quick solution. ”

After Sima Fu finished speaking in one breath, then the conversation changed.

"I wonder what Childe thinks?"

After listening to this, Cao Yu nodded slightly, but did not answer, but smiled faintly.

"If this boy can say such an opinion, he must also be a proficient person in mathematics, facts speak louder than words, why don't we have a competition?"

"But it's disrespectful!" Sima Fu strode up to the podium.

Sima Yi's head next to him was running at high speed, and he didn't feel right, but he couldn't think of anything wrong.

"I don't know how Cao Gongzi wants to compete!" Sima Fu asked.

"Since it is comparative mathematics, it is natural to give priority to arithmetic!" Cao Yu looked at the bottom of the podium, and then said.

"Let's ask the people below to come up with 10 random arithmetic problems! Whoever answers first and gets it right wins. ”

"That's a win!"

Young people are already very competitive, especially Sima Fu, who is known as one of Sima Bada.

Ten arithmetic questions were quickly randomly selected from below.

It's hard to blend in.

1: Wu Qianbai Bai 30 minus Qi Baiwu

2: Three thousand Wu Bai Qi three plus three hundred three

3.

4.

……

"Master Cao, it seems that I will win this time!" Looking at these topics, Sima Fu was confident.

"Let people do the calculations!"

Cao Yu nodded and took out a handful of dusty abacus from the drawer.

And it's still a legacy of the previous doctor.

"What do you mean by that?" Sima Fu saw that he only had one abacus, and he only gave it to himself.

If you want to win in this way, you can't win!

However, the next second.

"I don't need an abacus!"

I only heard Cao Yu's voice.

Everyone was dumbfounded, even with Sima Yi.

This arithmetic does not need to be calculated.

Can't you still count it with your hands?

And that's not all.

Sima Fu on the podium was also dumbfounded.

Then there was another wave of shame, frowning, and grasping the abacus.

Are you underestimating me!!

Don't blame me for embarrassing you for losing!

At this time, Lao Cao, who was peeping outside the window, was also confused.

Although I know that your nine chapters of arithmetic are awesome.

But this is also ......

That's!

Even a stupid tiger idiot knows how to calculate without an abacus!

Over time.

The race has begun.

Da-da-da-da!

Dadada!!

Sima Fu's voice resounded through the classroom.

Fingers kept fiddling with the abacus.

It's as if you're going to win the game with all your strength.

And Cao Yu next to him is the opposite.

Yawning and burnout.

In a daze.

After Sima Fu worked out the two answers, he started to leave.

The audience looked at Cao Yu's big appearance and complained one after another.

"You don't need to calculate, let others take two steps first, and see how you pretend to lose for a while!"

"Huh! Brother Tai, if you are serious, you will lose, you didn't find out, he did it on purpose. ”

"It turned out that I was making excuses for losing for a while!"

"Cut, I'll just say, I thought there was really a way in the world that didn't need to be abacus!"

And yet in the next second.

Everyone was shocked.
