Mozun is forced to farm

As soon as the four characters came out, the house was full of silence.

Lin Zhu originally wanted to see everyone's suddenly enlightened expressions, but after speaking, seeing them as if they hadn't heard, he put his hands in his hands and said uncertainly: "Could it be...you can also use magic to solve this?"

Lin Shuangjin vaguely remembered this book, and it was roughly about settling accounts, but she saw the strange atmosphere in the audience, and she didn't dare to speak.

Xie Xuechen thought that he had obtained some fragments and only a single copy, but he was speechless when he heard the words: "Arithmetic? What's the matter?"

"Arithmetic." Su Hongxiu said unsurely: "Multiplication and division, etc., you can know it with just one touch of the abacus. It doesn't feel difficult."

Lin Zhu guessed that they probably misunderstood, thought for a while and said, "Give me the simplest example."

"Assuming that the nine immortal sects form an alliance, they can form a pair or a group. In the worst case, how many ways are there to form an alliance?"

"What's the matter?" Su Hongxiu said without hesitation, "Of course there are nine kinds—no, uh, ten kinds?"

Xie Mingyan originally wanted to laugh and say how the nine immortal sects could form an alliance, but just as he was about to answer, he stopped the car.

No, this question seems simple, but in fact there is a lot of mystery in it.

The first eight can form an alliance, and the last eight can also form an alliance, so the changes here are endless...

Seeing that Su Hongxiu was still snapping his fingers, he snapped and said, "Countless! Isn't it!"

Lin Zhu shook his head regretfully.

The educational books of immortals, demons and Taoists are different. It is true that there are a lot of enlightenment by reciting scriptures since childhood, but there are very few exposure to this kind of calculation scriptures.

Xie Xuechen lowered his head and calculated again, first counting how many changes would be possible if there were only three people forming an alliance, how many changes would there be if five people formed an alliance, and finally pushed to nine people.

"Nine plus eight plus seven...and so on to one, the answer is 45, right?"

Lin Zhu wanted to nod at first, but he was not sure at the moment, scratching his head and said: "Do you want to see the order of the alliance?"

"Naturally, there must be a competition in forming an alliance," Su Hongxiu immediately said, "There are countless rules for whoever grows up!"

"Wait, what does this have to do with order..."

A group of people were messing about for a long time, and there was a dog barking outside the door, and it was Fa Cai, who was thousands of miles away, swimming over with a package in his mouth.

In the water-proof pocket are not only "Nine Chapters of Arithmetic", but also several classics such as "Five Cao's Arithmetic" and "Sun Tzu's Arithmetic".

Su Hongxiu was overjoyed, and kissed Gouzi forcefully, before turning the pages of the book to find the topic.

Leaving Mozun standing next to the scholar, he hesitated to speak and stopped talking.

In the end, I still asked: "So... how many kinds of alliances can be formed at most?"

Lin Zhu treated each other frankly: "I'm also confused."

"..."

Time flies like an arrow, and the one-day deadline passes in the blink of an eye.

Zihai Dongfu is located between the sky and the sea, the time is still like the world, and you will not miss the spring test in a blink of an eye.

When Xie Xuechen took his seat at the table, he thought about it extra carefully, and realized that something was wrong.

He seems to have been changed too much by the world.

Become patient and meticulous, and worry about everyone's concerns and worries.

He didn't know if it was only for Lin Zhu alone, or for everyone.

If my father was still alive, seeing that the cold-faced thug he had raised since childhood has become a little more tender as an ordinary person, he might be able to jump out of the coffin with anger.

Today is the auspicious day for Zihai Su's family to publicly choose a son-in-law. Not only many friends of Su Hongxiu came from all over the world, but also relatives and friends came here one after another.

There are white deer riding clouds outside the gate of the cave, and black-maned horses riding waves pulling carts outside Haibo, and all kinds of monks and fairy couples come to join them. It is also rare to encounter such a new thing.

The venue for the banquet was chosen to be the best viewing place, Liuhai Court.

In front of me, Pingting, a merman, came and went, and all kinds of delicacies were served in turn.

Later, there was a dancer Hida playing the pipa, who never tires of all kinds of tricks.

In such a feast, the old lady and the lady slowly took their seats, followed by Su Hongxiu, who was dressed up, with a pale face and the reddest lip paper, standing on a high position like a pale cherry, with pearls on her head. Huaguan's work is complicated and delicate, and even if you are not married, you can see the handwriting.

While playing music and singing and dancing, three candidates appeared in turn to salute all the guests present.

Xie Xuechen was about to drink, when he heard Lin Zhu calling him with his spiritual sense.

"Who are these people...?"

They were a little far away, and he couldn't hear their self-introductions clearly.

Mozun wanted to answer, but he forgot the names of these three people for a while, and simply and rudely took three nicknames.

"The first one, the one in the flowered shirt, you can call him Big Oyster."

Lin Zhu almost choked on the tea.

"This is also a person from the nearby area. It is rumored that he has a thousand years of Taoism," Xie Xuechen said indifferently: "This kind of thing is just like how long the thing is. Year."

Lin Zhu originally wanted to ask you how long the matter was, but was worried about being stared at by him, so he swallowed the words silently.

Unexpectedly, the latter sneered: "I heard it."

"I didn't say anything." Lin Zhu looked at him seriously: "A gentleman never asks such a hooligan question."

"It's okay to tell you." Xie Xuechen glanced at him: "Three or four feet, usually around the waist."

Lin Zhu dazedly compares his skills, and then realizes that this guy is cheating on him.

The latter squinted his eyes and smiled, taking a sip of wine in a good mood.

"Big oysters are also worshiped with a lot of incense in the nearby coast, and some people are honored as Qingli Daojun, hoping that he will protect them to harvest more fish and return to the sea safely."

Although Xie Xuechen was not familiar with him, but looking at his face and temperament, he did not look like a villain.

Seeing the dancer move away, Lin Zhu saw the second person's crown jade clearly, and whispered.

"It's him."

It was the man who was exposed to the question the night before yesterday, with a beautiful body of rocks dangling around, very conspicuous.

Xie Xuechen had met this person several times, but he still couldn't remember the name.

"This man...you can call him Brother Stone."

"He is a businessman who specializes in reselling Lingshi and Lingyu. Although he is also a disciple of a famous sect of Taoism, he has made a name for himself with his business skills. He is very popular among immortals, and he is well-informed about his contacts and information."

Lin Zhu and Su Hongxiu have a very good relationship. After all, they feed pigs together all day long. Hearing this, he worries about her.

"Could it be that her sister sold her like this in order to improve her cultivation by leaps and bounds?"

"It's possible, it's hard to say."

When it came to the third one, Xie Xuechen squinted for a long time, not sure.

"Looks like Danxiu, he should be the leader of some sect."

After the three rounds of toasting, the ceremonial officer finished reading the Zhao Wen aloud, and the old lady nodded slightly, indicating that the test of choosing a son-in-law could officially begin.

Before the Yiguan unfolded the coral scroll, Su Hongxiu suddenly stood up.

"Wait a minute."

Everyone immediately turned to look at her, eagerly waiting to eat melons and watch the show.

Su Hongxiu didn't want to slap her old lady in the face, so she said obediently, "Since you are choosing a son-in-law for me, how about choosing me for the first question?"

Anyway, the three questions are all used to screen out the wishful husband, and the order is not important.

If her questions were so difficult that she screened out all three, that would be God's will.

Su Qingrui frowned slightly, intending to stop it, but the old lady tapped the whalebone stick lightly, smiling kindly.

"It's all right. If you like it, you can come first."

Su Hongxiu regained her composure, and signaled the ceremony officer to take away the coral scroll in front of her table, and read the questions in public.

The three candidate husbands had also paid attention to her a long time ago, waiting for her success after marrying, and some of them even winked and smiled at her specially.

The ceremonial officer coughed twice.

"Listen, three!"

"Today there are five sheep, four dogs, three chickens, two rabbits, worth 490; four sheep, two dogs, six chickens, and three rabbits, worth 170; three sheep, one dog, seven chickens, and five rabbits. , worth 950 yuan; two sheep, three dogs, five chickens, and one rabbit, worth 860 yuan. What are the prices of sheep, dogs, chickens, and rabbits?"

As soon as the words fell, everyone in the field showed the same blank expressions as before.

……What? ?

What is this asking? ?

The three candidate son-in-laws were confused, so they could only raise their hands to signal the ceremony officer to read it again.

The little head changed a piece of paper and started to memorize the numbers, counting the same with a sad face.

Something magic happened.

Not only the three of them counted, but also the adults and children eating melon seeds and almond candies in the circle couldn't help counting, as if they were drawn into some kind of whirlpool.

Five sheep minus four sheep, but there are still two dogs owed three chickens and one rabbit, how will this be settled...

For a while, those who didn't have a pen looked for a pen, those who had a pen gnawed on a pen, and even the voice of gossiping and gossip disappeared.

The eldest lady also pinched her fingers in a bewilderment for a long time, and then she reacted after she got tangled.

I don't marry her, I'm a fart.

Su Hongxiu saw that everyone started to solve the problem inexplicably, and vaguely understood that "Nine Chapters of Arithmetic" is really an amazing book, so she turned her head and used her spiritual sense to send messages to her friends everywhere.

- not bad! !I should be stable! !

Lin Shuangjin went back immediately to comfort her.

- Mmmm, I feel like that too!You can see that the three of them have already been transformed into tables.

Next to him, Jie Mingyan interrupted.

- Is there a time limit for this? It can't be counted until tomorrow.

Su Hongxiu patted her chest proudly.

- Just a stick of incense time!You are not allowed to communicate with outsiders, you can only think for yourself!

Chatting back and forth, I couldn't hear Lin Zhu's voice.

Su Hongxiu looked around and saw the two of them sitting together, and urged Mozun to join the chat with the scholar.

- can he hear us

- how about you help him ?Whisper to translate? ?

Lin Zhu finally stopped writing.

-can hear.

He looked sad, not happy like the others.

- Hongxiu, is your question too easy?

Here Lin Shuangjin was waiting to hear Su Hongxiu's simple and quick negation, but the latter hesitated rarely.

- is it easy...?

Lin Zhu was also a little confused.

-Jane is not simple, don't you know.And I've figured it out...

Su Hongxiu scratched her head anxiously.

- After reading for a long time, I was able to understand a few questions, and I chose the one that seemed clear to me.

Others are all about how deep the pool is and how many cones are accumulated, and there are some nonsense such as the root secret rate in the high depths. She can't read the questions clearly and she dare not take risks.

It's over, no one will be able to solve it.

At this moment, the big oyster monster stretched out his sleeves and stretched out his hand, and actually conjured up a group of sheep, dogs, chickens and rabbits in front of the court, and waved left and right into four groups, standing in order.

Lin Zhu became anxious.

It's broken, he's going to be deformed on the spot.

The author says:

Math teacher (with a loud shout): Look at me, everyone! !I'm going to transform! !

Oh yes! !This question! !Five hundred Jinjiang coins will be given out to those who answered correctly in the first ten comment areas, and [-] coins will be given out to [-] random comments! !Let's all be happy, let's do the math
