The strongest mathematics of this era were the Arabs, and Damascus was at the moment experiencing the most glorious years of its life. If there is a heaven on earth, Damascus will be in it; If heaven were in the sky, Damascus would have the same name.

Damascus had a glorious culture in this era, and the Damascus Library, which has a collection of books from all over the world, is famous, and even in the Great Song Dynasty, people often praise the magnificent library.

Under such prosperity, the mathematics, geography, astronomy, and physics of the Arabs have reached the peak of this era, and they burst out with brilliant brilliance in the mountains.

And East Asia in this era, the talent in mathematics is relatively unsightly, after the disputes at the end of the Tang Dynasty and the war of the five dynasties and ten countries, the cultural heritage left to the Great Song Dynasty is really very little, in the official history of the Northern Song Dynasty can be regarded as a famous mathematician is Jia Xian alone, but in the history of mathematics enough to be famous for thousands of years "Yellow Emperor Nine Chapters of the Calculation of the Grass" can only come out after a few decades, and now Jia Xian has not been born.

Of course, a lot of the Song Dynasty mathematics is written in a mess, that's not right, the four operations or something is still not a problem, and the arithmetic is mainly focused on the application problem, after all, before the theory is not summarized, no one knows how to describe it, so the application is the mainstream.

For example, the following questions are now written by the Great Song Dynasty, and their questions are construction questions, which are relatively difficult canal earthwork problems.

When the topic came out, Song Beiyun and Yan Shu both began to calculate, and the relative Yan Shu calculated the earthwork itself while Song Beiyun calculated the input cost, compared to how much soil to dig out, Song Beiyun was more concerned about how much money to invest.

In the end, it was concluded that a canal of about 700 kilometers would need 192.2 million yuan of capital to be completed in its entirety, without taking into account inflation.

This is equivalent to about 80% of all the coins in circulation in the market so far in the Great Song Dynasty, that is to say, digging a canal with pure manpower is tossing with all the resources of a country, and the Great Song Dynasty will be exhausted after digging the canal.

"It's not a good deal." Song Beiyun touched his chin: "You said that if Ying Long when Dayu controlled the water, how good it would be to dig the canal, and the fuel consumption per kilometer was thirty big fat pigs, which was perfect." ”

Yan Shu looked at Song Beiyun, who was saying strange things: "What are you counting?" ”

"I'm saying that Emperor Yang of Sui is really amazing, his Grand Canal has blessed hundreds of generations."

Hearing him say these strange words, Yan Shu's eyes were a little strange, but he didn't get to the bottom of it, after all, he looked at Song Beiyun and Song Beiyun looked at him the same, that is, there was something wrong with genius after all.

Fortunately, the big Song Dynasty in arithmetic was not completely crushed, and it was not until the seventh question that they lost their points because of a small mistake, and finally lost a ride.

But it's really a pity, because Dakin's people cheated, they secretly changed the concept, made a bad hand in the application problem, deliberately came up with a question with unclear meaning to confuse, and finally misled the entire Da Song team's thinking direction was wrong, Beipo wanted to get up to protest but in the end he didn't bother to argue, and silently ate this dark loss.

The second game is much more exciting than the first, which makes people see that Da Song's straw bag is not so straw bag, and it still has the strength to fight, but Dajin's fraud makes Yan Shu upstairs a little uncomfortable.

"Straw bales are straw bales, but this is not like a gentleman's doing." Yan Shu flicked his sleeves: "I'll go." ”

"Wait a minute......" Song Beiyun grabbed him: "You wait for me, it's not time yet, it's still the same sentence, let the arrow fly for a while." ”

Yan Shu was still indignant, and he wanted to go down and press the deceitful bastards to the ground and then pull them on their heads.

And the news of the second Jin Dynasty fraud was quickly spread outside, and the Song people, who lost two in a row, can be said to be excited, and heard that the Jin Dynasty envoy was cheating, and immediately those who lost money rushed in to devour the Jin envoy alive.

But at this moment, the forbidden army of the brigade ran over and set up a position in front of the Heavenly Fang, and no one could approach it anymore, and the head of a Honglu Temple also came out to explain to the people below.

And when the crowd is enthusiastic outside, the third round has already begun, and the topic of the draw is couplet.

It's just that at this time, in the small corner on the second floor, only Zuo Rou was lying on top and looking down.

"It's a good thing to do poetry, and it's very interesting." He Huan, the C-rank player of the Jin Country, that is, the man who was thought by Yan Shu to have a crush on him, stood up with a smile on his face: "The couplet is together, although it is a small path, it is also interesting and tight, fellow students, listen to my couplet." ”

With a bit of banter on his face, he said with a smile: "It's just a joke, everyone is not surprised." This upper link is to laugh at the grandson in front of the door, begging for this lower link. ”

When the genius of the Great Song Dynasty heard this, his face turned green with anger, and this Shanglian was clearly mocking the people of the Great Song Dynasty at the door.

How can such a thing be endured? Beipo was so angry that his chest was panting rapidly, but the more this was the case, the more his brain was angry, and he hammered the table hard, as the C position of the Great Song Dynasty, he was obviously out of standard today, but in this banter, he couldn't fight back, which made him almost gush out of the old blood.

Although the talents of the Great Song Dynasty were angry, no one could answer, and they couldn't answer it because of the banter in it.

At this moment, the door at the entrance of the hall was opened, and two people walked in outside, followed by the same joking: "After drinking, the ancestors are angry." ”

For a while, everyone in the room looked in that direction, but they saw two young people striding inside, Song Beiyun was walking in the head, and behind him was a handsome boy with a face as heavy as water shaking a folding fan.

When they saw Song Beiyun on the north slope, they suddenly felt like they saw a savior, but when He Huan of Jin Guo saw Yan Shu, he was like a great enemy.

"It's not very neat, since this genius said a casual joke, then I will take it as a joke, don't worry."

Song Beiyun arched his hand to He Huan: "The Great Song Dynasty is a nameless little showman, Song Beiyun." ”

Yan Shu stepped forward and glanced at He Huan up and down, without even saying a word, just putting his hand behind his back: "Hmph." ”

He Huan suddenly sat on the stool, his face turned pale, he couldn't even care about being angry, but he didn't expect this Yan Shuyan uncle to come.

However, the others didn't pay much attention to Yan Shu, mainly because they had only heard of Yan Shu, but Yan Shu had never played with these rookies, so they didn't know each other.

But this newcomer Xie Yuan Song Beiyun, most of them are familiar, after all, they called a chicken together and played for several days, they can be regarded as very iron brothers.

"Brother Xian, you're finally here!" Beipo was so excited that his hands trembled: "If you don't come again, I don't know what to do for my brother." ”

"It's normal for things to go up and down." Song Beiyun said with a smile, and when he spoke, his eyes kept glancing at the Jin State Mission next to him: "It's just that some people are not righteous, this is not good, playing a game is so utilitarian." ”

After speaking, Song Beiyun turned around and walked in front of He Huan, and stretched out his fingers: "You, take the question." ”

Song Beiyun is crazy, of course he is crazy, he is not weak, and there is also the god of war Xiao King Kong by his side, if he is not crazy, he is sorry for his identity as a traverser.

Then He Huan squinted his eyes and looked at Song Beiyun, and after finding out that it was not Yan Shu, he also stood up with a smile: "This descendant, let's let Uncle Tong come." ”

Yan Shu pouted beside him, whispered "", and scolded Song Beiyun's words: "Damn, mentally retarded." ”

Song Beiyun frowned: "Don't pick it up, right?" ”

Yan Shu turned around at this time and pretended not to see anything, but He Huan just chuckled: "That's okay, let's make a question." ”

Song Beiyun opened the fan and read slowly: "Eight hundred miles of Dongting, rushing to the bottom of the eye." Draped in the shore, the joy is boundless. Look: Dongxiang Shenjun; Xizhu Lingyi; The north goes meandering; Nanxiang Su. Masters of rhyme, why not choose to win. Take advantage of the crab island Luozhou, comb the wind and fog sideburns. More frequent reeds, dotted with some green feathers Danxia. Don't be disappointed: fragrant rice all around; Ten thousand acres of clear sand; Nine Summer Hibiscus; Three spring willows. ”

After reading it in one breath, the scene exploded with a buzz, and even Yan Shu was stunned...... This raised hand king fried dear.

Song Beiyun tapped three times on He Huan's table with his hand to show mockery, and then slowly walked back to the talented camp of the Song Kingdom with a white paper fan.

As for the people at the scene, they all exchanged heads and ears, this couplet...... , it's not just long, they can't write a lot of words in it, how can they not write words?

"Oops, oops." Jin Ling'er shook the small fan lightly, already overjoyed: "How is this good, he is here." ”

And on the other side of Daikin, they have begun to circulate to each other, and some words that they don't understand have been replaced by those with clear meanings, but it doesn't matter, I want to match this ...... It's a bit too much of a bully.

"A stick of incense." Song Beiyun pointed to the incense next to him: "It's faster, if you don't come up, you'll lose, and if you lose, it's two to one, but it's going to be overturned." ”

The more agitated he was, the more irritable the person on the other end became, and when he was impatient, his mentality was the same as that of Fang Cai's north slope, and his brain became a mess, and he couldn't even speak clearly.

And Beipo let out a sigh of relief, took a sip of tea with a hand that was still trembling, and said to the prince of the Wang family who was sitting like a mountain on the side: "My brother Beiyun is here, and this plate is stable." ”

The prince of the Wang family is now addicted, yawning again and again, he is already too fugue, and he hasn't even heard Beipo's words.

Seeing this, Beipo could only shake his head, and then raised his head and said to Song Beiyun: "Brother Xian, if you come earlier, you will definitely be able to kill these golden barbarians and lose their armor." ”

"Wouldn't that be boring?" Song Beiyun flicked his hand at Yan Shu: "Actually, I'm not the main attacker, he is." ”

Yan Shu only squinted at Beipo and them, and did not salute or anything like that, Beipo asked curiously, "Who is this person?" It looks a little arrogant. ”

"Uncle Linchuan Yan Shuyan."
