There is a White Horse Temple at the entrance of Xiangjiang River to Dongting Lake, because Qu Yuan was exiled, he once rode Bai Ji to cross the river here, and because Du Fu traveled to Dongting to write a poem "White Horse Temple" here, the White Horse Temple is not far away and there is a big village courtyard by the mountains and rivers.

At this moment, there is laughter and laughter in the courtyard, and the aroma of wine and meat is fragrant.

"Mr. Sima, I toast you!" The middle-aged man in a big red robe raised his glass to toast Sima Ming, and Sima Ming was flattered and raised his glass and drank it all. "Mr. Wang," the middle-aged man looked at Wang Anshi, who was smiling and eating vegetables on the side.

There was a sudden silence all around, a smile appeared on his face, and Qin Chao also showed a funny look.

The middle-aged man in a red robe is called Zu Rihuan - a big bull who came from the broken void.

Everyone knows that the greatest mathematician in ancient China is called Zu Chongzhi, but there is another person that few people know, and that is Zu Rihuan. Zu Rihuan is the son of Zu Chongzhi, both father and son are very rich in mathematical achievements, "Fixation" is their masterpiece, is listed as one of the "Ten Books of Calculation", but lost in later generations.

Zu Rihuan solved the unsolved problem of Liu Hui in the Wei and Jin dynasties - calculating the volume of a sphere, in which he used the principle of 'the power potential is the same, the product is not different', which was not discovered by the Italian mathematician Cavalieri until the seventeenth century in the later West, more than 1,100 years later than Zu Rihuan.

Of course, father and son are best known for their achievements in mathematics.

However, astronomy, Zu Chongzhi created the "Great Ming Calendar" and was the first to introduce precession into the calendar, and Zu Rihuan twice proposed to Emperor Wu of Liang to modify the calendar to correct the estrangement of He Chengtian Yuanjia calendar.

Mechanically, Zu Chongzhi once built guide cars, tools, thousands of miles of boats, water mills, etc., all of which were extremely effective.

Zu Rihuan and Zu Chongzhi's main research directions are mathematics, astronomy and mechanics, naturally their situation is the same as Shen Kuo, and they are incompatible with the orthodox school, so Zu Rihuan came here after breaking the void. It was found that the spurned 'cheap science' has become a sweet spot for everyone in the entire martial arts world to study.

Overjoyed, mixed like a fish in water.

And because the Qin Dynasty attached great importance to Zu Rihuan, he was introduced to interact with Shen Kuo, if there has been any great progress in science and technology over the years, it is that Zu Rihuan and Shen Kuo have made amazing achievements in mathematics, and the best thing is that two years ago, the two of them published a book - "Coordinate Geometry".

"He is worthy of being the greatest son of mathematics in Chinese history. Qin Chao was very emotional in his heart. Coordinate geometry is the analytic geometry of later generations.

Descartes's analytic geometry is very simple to learn in later generations, as if it were like that, but this is the view of hindsight, in essence, analytic geometry unifies 'number' and 'shape', and introduces the idea of variables into mathematics, which really opens a door and is an epoch-making change in the history of mathematics.

Therefore, Engels once said, "The turning point in mathematics is the Cartesian variable, and there are variables." Movement enters mathematics, there are variables, dialectics enters mathematics, and with variables, differentiation and integration become necessary at once, and they arise immediately,......

Many people have given high praise to analytic geometry.

Because of this, as soon as Qin Chao saw Zu Rihuan and Shen Kuo, they actually figured out analytic geometry so quickly. Almost all of them were a little confused, and then they spent a lot of pen and ink in the newspaper and spared no effort to praise it.

also because of the praise of the Qin Dynasty. It turned out that the analytic geometry that was not very popular in the martial arts world immediately rose in value, and Zu Rihuan became a grandmaster-level figure in the martial arts world.

Shen Kuo can also be regarded as a salted fish turned over, and he is no longer bullied by Mrs. Zhang as before, at least, Zu Rihuan will find Shen Kuo to discuss knowledge, and Mrs. Zhang will definitely hide far away.

Zu Rihuan became famous. I don't know how to look at Cheng Yi's granddaughter Cheng Jingsi, or Cheng Jingsi chased after her ancestor Rihuan, so there was today's wedding.

Seeing that Zu Rihuan was about to toast Wang Anshi, he secretly laughed one by one.

"I admire Mr. Wang's courage and foresight, and you can come to my wedding banquet. Rihuan was flattered, this cup of bad wine, and hoped that Mr. Wang would not refuse. Zu Rihuan said. Wang Anshi waved his hand lightly: "I never drink." Zu Rihuan was stunned for a moment, and it was not to enter with a wine glass, nor was it to retreat.

"Okay, Jing Shuo, Jiefu really never gets drunk, don't talk about you, it was when he was working under Bao Zheng, and Lord Bao toasted him and he coldly refused, at Duan Haifeng's wedding a few years ago, he still didn't give face, you toast him with a cup of tea. Cheng Yi said with a smile.

"I see. Zu Riheng smiled loudly, gave Wang Anshi a cup of tea, and then looked at the Qin Dynasty, and the surroundings were quiet again.

"Mr. Qin, Jing Si once studied Tai Chi class, and now she is a member of the Tai Chi Club, it can be said that you are her teacher, since I came to this world, I have also been taken care of by you, allowing me to come into contact with the advanced science and technology of Lingnan, so in my eyes, you are also my teacher. Zu Riheng said in a deep voice.

"Haha!" Qin Chao smiled, "Jing Shuo, I'll do you a little favor, I can't afford it." ”

"Mr. Qin, how dare my ancestor not remember your favor to me, but ......" Zu Riheng's voice suddenly sharpened, "Over the years, I have asked you for advice on mathematics, mechanics, and astronomy, but I either can't find you, or I have been rejected by you, once or twice, eight times or nine times, but thirty-seven times, each time has been rejected, Mr. Qin, what do you mean by this?"

"This ......" Qin Chao smiled bitterly in his heart, why he didn't want to talk about academics with Zu Riheng, firstly, the Qin Dynasty was indeed very busy, the columns of the "New Youth" newspaper could not be stopped, and the continuous gradual reform of the Ling Affair, every reform had to be painstaking, the academic affairs had to be busy, the longevity algorithm had to be studied, and the research on the aura was a super time-consuming household, in addition, the Qin Dynasty did not want to owe it to his family, so he could spare time to spend it on accompanying his family.

The most important thing is that the Qin Dynasty is unwilling to do everything by itself in science, and it is far away from Zu Riheng, and it is of greater significance to the Qin Dynasty to let Zu Riheng make scientific research results by himself.

"Jing Shuo, I take a great fancy to you, I naturally have my reason to stay away from you, you don't have to worry too much. Qin Chao said with a smile.

"If you don't have a lot of heart, how can you not have too much heart?" Zu Riheng raised his voice, "I also know that Mr. Qin, your noble family is busy, and I don't want to dwell on the past, this time, my big wedding, Mr. Qin, you can afford it." I shouldn't have bothered more, but I have some doubts in my heart, and I always feel unhappy if I don't solve it, so I want to ask Mr. Qin to promise me once. This wedding has solved some of my confusions. ”

"Jing Shuo, why are you so troubled, this is a great banquet ......" Qin Chao shook his head.

"We are all scholars, and we can leave everything behind, but learning is the first class. Zu Riheng exclaimed with a sigh of wine, "I think not only I, Zu Riheng, want to see Mr. Qin's arguments, but others must also be like this." ”

There was a sudden commotion all around.

"Haha, Qin Gongzi, you can explain Jing Shuo's doubts. ”

"Qin Gongzi's article is sharp. Everyone can see it, but the on-site answer, this kind of thing is rare for everyone, and we can just take a look!"

Qin Chao's brows furrowed.

Zu Riheng put the wine jar away, stared at Qin Chao with red eyes, and said: "Mr. Qin, for me, learning is more important than everything, if you don't want to point out the contemptible people today." I'll just ...... I'll just ......"

"What?" laughed all around.

Zu Riheng rolled up his sleeves and said in a rough voice: "I won't be a cave room!" There was laughter all around. "Okay!" Qin Chao said in a deep voice. Squinted and glanced at Zu Riheng, whose face was firm. "This ancestor Riheng seems to be serious. Qin Chao naturally could see that Zu Riheng was not joking, if he didn't agree, this person might not have sex with Cheng Jingsi from now on.

"Mr. Qin, please wait a moment. Zu Riheng had a child-like happy smile on his face, and his big hands stained with wine took them into the clothes in his arms.

"Mr. Qin, Jing Shuo is one of the most outstanding scholars among our visitors from outside the world. ”

A gentle voice rang out: "And you are also the most outstanding leader in your world. Jing Shuo asks you for advice, which represents the contest between our visitors from outside the world and your world. ”

One by one, they looked at the old man in Tsing Yi who was talking, this person was a tiger's back, two meters tall, and had extremely long hair on his skin.

"Zu Shengcai. What do you mean?" Han Zhongyan snorted. The Qin Dynasty frowned slightly, over the years, there have been visitors from outside the sky, and Zu Sheng is the visitor from outside the sky who came nine years ago, he established the Tianyu Gate, and many outsiders have announced to join the Tianyu Gate, so the Tianyu Gate has also become a very distinctive sect in the martial arts world.

At the beginning, the martial arts people in this sect did not take it seriously, but five years ago, the Tianyu Gate began to make achievements in science, especially Zu Chongzhi's mathematics, Zu Shengcai's own "Qu Guang" and the "Meteorology" of Kalodo, another genius of the Tianyu Gate, are of a very high standard.

In particular, everyone is obsessed with the research of the aura of the sky control and the picking of longevity fruits, which are naturally ignored scientifically, and the Qin Dynasty has not made any efforts in science over the years, there are no tigers in the mountains, and the monkeys are called kings, and some of the achievements of Zu Chongzhi, Zu Shengcai, and Kalodo are particularly eye-catching.

It's nothing.

But Zu Shengcai became extremely arrogant because of these achievements, saying that the local faction was nothing, and even he set up a ring with his knowledge and proposed to Liu Qin, although Liu Qin ignored it and became unhealthy, but this has also become a shame for the local faction in the martial arts world.

"We are outsiders, our minds are not stupider than your natives, and our morals are not weaker than yours, but in your eyes, we have always been different, and we have always been inferior. "The ancestral saint is like thunder.

Everyone's faces were calm, for so many years, there have been many visitors from outside the sky, and everyone is not stupid, so they naturally have touched a lot of laws, for example, the science of the world where the visitors are located is lagging behind here, and the martial arts are lagging behind here.

Therefore, someone has proposed a law that makes all visitors from outside the world uncomfortable.

There are levels in the world, and the broken void is to enter the high-level world, and all the people who come to our world are in a world that is lower than ours.

"Although over the years, our Tianyu Sect has made great achievements, but when we get along with you, when we talk about this, you are often what it is, compared to the academic works published by Gongzi Qin and Duan Haifeng, this is a small thing. Zu Shengcai's voice was full of disbelief, "Gongzi Qin, I admit Gongzi Duan's achievements, but those are all from the past, what has he taken out over the years?"

"Nothing!" Zu Shengcai's fierce eyes glared at Liu Qin, "Mr. Liu, where is my Zu Shengcai not worthy of you?" Every time I talk to you, you always use Duan Haifeng and Qin Xianao to prevaricate, this time do you dare to bet with me!"

Liu Qin frowned, Zu Shengcai is a good talent, and he has a deep affection for her Liu Qin, it is indeed a good match, but what ...... There are other people in her heart, so every time Zu Shengcai comes to entangle, she can hide and hide, and if she can't hide, she will try her best to drive him away, so she naturally uses Duan Haifeng and Qin Xianao as shields from time to time.
