Datang: My virtuous brother did not expect that I am the emperor!

"Little brother, how can you say the answer casually!"

Changsun Wuji looked at Zhou Yaoting eagerly!

"Uncle, use Su Chen's numbers, multiply and divide, and you can figure it out. It's very simple!"

Chapter 80 Su Chen Numbers and Multiplication and Division

"Su Chen numbers and multiplication and division, what is this?!"

When Changsun Wuji heard what Zhou Yaoting said, he was extremely curious, what kind of magical method could allow a child to calculate such a complicated arithmetic casually!

You know, the Ministry of Households needs to spend countless manpower and material resources to calculate a thing!

Many people are required to calculate with an abacus at the same time, but the method described by this child seems to be able to calculate the answer very quickly!

Thinking of this, Changsun Wuji looked excited!

He hurriedly asked, although the other party was a child, Changsun Wuji was still very serious!

After all, the three of us must have my teacher, Changsun Wuji found an excuse to save himself some face!

If there is such a magical method in the world, I am afraid that his household department's work efficiency will be greatly improved in the future!

Merchants in the entire Tang Dynasty will also be blessed because of this!

"Come on, uncle, I will teach you!"

Zhou Yaoting came over, holding a piece of paper in his hand!

Although he doesn't like talking to strangers, Mr. Su taught them this way for free!

Mr. Su once said, let a few of them pass on this arithmetic method, life after life!

So he is obliged to teach others!

Walking in front of Changsun Wuji, he spread out the paper and put the pen in his hand on the white paper!

He slid down in front of Changsun Wuji!

"This is 1. This is 2..."

1,2,3,4,5,6,7,8,9,0,

Zhou Yaoting taught Changsun Wuji number by number!

Zhou Yaoting wrote down the ten numbers in a while.

"This is called Su Chen's number, which is simpler than Datang's counting method!"

Zhou Yaoting, who had been with Su Chen for a long time, saw the eldest grandson Wuji who was dressed as a scholar, and said that he was neither humble nor overbearing, and it was a great change from the silent Er Gouzi at that time!

"This method is very good!"

Changsun Wuji spoke excitedly!

Heart is very shocked!

This is called Su Chen's numbers, which are much simpler than Datang's traditional numbers. Each number does not exceed three strokes, which greatly improves the efficiency!

And it is very easy to remember, even a farmer can memorize this thing no more than three times!

It shows that this thing can be spread very easily!

Li Er and the others saw Changsun Wuji being tested by a group of children just now, and they were all watching behind him at this time!

Seeing Changsun Wuji's fart just now, and now respectfully learning Su Chen's numbers behind a child, everyone wanted to laugh!

However, several people were extremely shocked when they saw this Su Chen figure!

Li Er felt that his virtuous younger brother was so unfathomable that he could even be so proficient in this kind of arithmetic, he was really a god!

"I don't know what multiplication and division are!"

After seeing the magic of Su Chen's numbers, he really wanted to see what kind of magic this multiplication and division is!

"Come and let me demonstrate it to you!"

Saying that, Zhou Yaoting casually wrote down a few Su Chen numbers and a strange symbol from the white paper!

"13*12, do you know what it is equal to!"

Zhou Yaoting looked up at Zhangsun Wuji!

Changsun Wuji shook his head.

If this thing had an abacus, he might still be able to calculate it, but now he doesn't have anything on hand, so how can he calculate it!

"Look, I'll teach you!"

After speaking, Zhou Yaoting started to write on the blank paper!

He first listed the two Su Chen numbers on the white paper!

"Two three get six, one gets one..."

Zhou Yaoting muttered to himself!

After a while, the answer appeared on the white paper!

"156!"

Everyone in Changsun Wuji was dumbfounded!

This is a child? !

Prodigy!

And this multiplication and division doesn't look difficult to learn, plus Su Chen's numbers!

Changsun Wuji gasped at the thought of this, his scalp went numb!

A look of horror!

This thing is too awesome!

If all his household members have learned Su Chen's numbers and multiplication formulas, the calculation will be greatly improved!

Changsun Wuji was full of excitement!

"Little brother, I don't know if I can learn Su Chen numbers and multiplication and division from you in the future!"

Changsun Wuji looked at him with hope on his face, he must learn this thing!

He can only teach it to his household department after he has learned it. As long as he takes this thing back, the household department will not be so busy in the future!

Hearing this, Li Er and the others behind were all shocked!

Changsun Wuji can be said to be the most proud group of people in Datang. He can teach a child to learn things, which is amazing!

"Okay, come to Mr. Su in the future, and I will teach you!"

Zhou Yaoting thought for a while, but he still agreed!

Right now!

A wolf howl came!

"Ah!!"

Cheng Yaojin just felt the hairs all over his body stand up, why are there wolves here? !

Cheng Yaojin blocked Li Er, looked at the wolf rushing in front of him and said in a deep voice!

"My lord, go, I will protect you, I will fight this beast!"

Cheng Yaojin regards death as home, after all he did not bring a weapon today!

"Old Cheng, don't be rude, this is my brother's pet!"

Li Er hurriedly pushed Cheng Yaojin away, it would be bad if this idiot hurt my virtuous brother's pet!

Moreover, the relationship between Xiao Hei and him is also very good now!

As soon as Cheng Yaojin got out of the way, Xiao Hei threw himself on Li Er's body and began to lick him affectionately!

Both Changsun Wuji and Cheng Yaojin were so shocked that they couldn't speak, they were extremely horrified!

How did you train a wolf to be so obedient!

This is too scary!

This wolf is more obedient than a dog!

It's really a fairy method!

"Xiao Hei, stop making trouble!"

Because Li Er often comes to Su Chen's place, the relationship between Xiao Hei and Li Er is very good!

Li Er also likes this obedient wolf very much!

Li Er patted Xiao Hei's head!

"I didn't bring you food this time, I will definitely bring you next time!"

Li Er laughed!

Everyone was also very strange when they saw Li Er talking to a wolf!

Xiao Hei seemed to really understand Li Er's words, and got off Li Er's body!

The whole group was even more surprised. Can this wolf understand people? !

As expected of a wolf raised by a fairy!

Now in the hearts of Changsun Wuji and Cheng Yaojin, Su Chen is really a magical figure comparable to a fairy!

After all, which of Su Chen's numbers and multiplication and division can be imagined by ordinary people!

If this thing becomes popular, it will greatly improve Datang's efficiency!

"I don't know where my virtuous brother is now!?"

Li Er couldn't find Su Chen's figure and asked the children!

"Mr. Su is sleeping in the backyard!"

The children replied in unison!

Li Er shook his head, why do he often sleep at noon!

"Come on, follow me to the backyard to meet my virtuous brother!"

With that said, Li Er led the three of them to the backyard!

As soon as they walked to the backyard, they saw a small pond rattling!

Li Er had known for a long time that there was a small pond in the yard, so he didn't care!

But at this moment, Changsun Wuji suddenly uttered a horrified voice!

"Your Majesty, what kind of fish is this fish!!"

Chapter 81 Shock from Koi

As soon as Li Er heard it, he looked towards the pond curiously!

After seeing the domineering-looking fish in the pond shining golden all over!

The whole person is also standing by the pond!

"What kind of fish is this, why is it golden?!"

Li Er asked curiously, as we all know, the ancient golden color can only be used by the Emperor's House!

Represents the emperor!

"Your Majesty, this looks like a carp!"

Even Fang Xuanling wasn't calm this time, and spoke in shock!
