only heard his voice but did not see his person, Zhang Shou could also sketch an unruly and domineering young man image in his mind. And the voice was a little hoarse, and he couldn't tell the age for a while, but according to the moment and the tone of the person's voice, he roughly inferred that this was the hoarseness of the adolescent voice change period.

If he remembered correctly, the man should have changed his voice between the ages of fourteen and sixteen, of course, sooner or later, but no later than sixteen to seventeen at the latest. In other words, the person who came may be the same age as Lu Saburo and him, or slightly younger.

And when he guessed like this, he soon found out that he had guessed correctly. Because among the four people who walked in with their heads held high, the one who walked in the forefront with a lively spirit did look very young, and his figure was very different from the roundness of the little fat man, but was well-proportioned and straight. If that's all there is to it, that's all, and a person has a very nice figure at the same time, but a face is a very pleasing round face.

This is different from Lu Sanlang, Lu Saburo wanted to be arrogant and arrogant at the beginning, but at this time, the round-faced young man, it was obvious that he was always smiling, and the two small dimples were still hanging on his face even at this time, just such a joyful image, which was not at all commensurate with the swaggering appearance of people walking in the forefront at this time, and it was even more incommensurate with this provocative move to the door.

The round-faced young man seemed to have noticed the expressions of everyone looking at him, his eyes were a little fluttering, and he cleared his throat before he spoke: "I am Ye Mengqiu from Guangping Mansion!" Today I know that I am presumptuous, but I heard that Dr. Zhang, the Guozijian who is in charge of Jiuzhangtang, is here today to crown Lu Zhu, the head of Jiuzhangtang, so I rushed in! ”

"The emperor summoned talents who are proficient in astronomy and mathematics, wants to revise the calendar, and I heard that the leap month will be canceled, dare to ask Dr. Zhang, is this true?"

Zhang Shou was speechless for a moment. He glanced at the emperor and saw that the Son of Heaven was casually bowing his head and drinking the sweet rice wine—after all, the banquet after the crown ceremony was based on etiquette—and avoided his gaze, he didn't know that this nonsense was spread by the emperor!

I think he joked at the beginning, saying that the calendar should be changed to 365 days in a year, 31 days in each month of 135780, 28 days in February, and 30 days in the rest of the months, and one day in February every four years, and 400 times the number of days in February for every 100 years...... In short, the Gregorian calendar. But that is to mention it once and forget it.

Because in the era of developed weather forecasting in later generations, the traditional lunar calendar except for the Spring Festival, Qingming and Mid-Autumn Festival holidays, coupled with the moon waxing and waning on the synodic day, other uses have been very few, and people do not need to look at the solar terms to add clothes and sow seedlings. But in today's era, although the lunar calendar with an extra leap month at every turn is troublesome, it still has the practical significance of its existence.

The emperor is simply a pit man!

He didn't even know how the emperor let the news out, and what he said, to deny it, now that these guys are coming here in a menacing manner, if he pushes it, he really looks weak. Therefore, after thinking about it, he smiled faintly: "Gao Yuan, let's talk about it." ”

Just being called by a completely irrelevant person by his least favorite name, Lu Sanlang was so angry that he was smoking, so Zhang Shou's voice was high, and he only felt as comfortable as if he was soaking in a hot spring.

At that moment, he directly pressed the table, Huo Ran got up, and shouted fiercely: "The emperor rebuilt the calendar, so he summoned talents who are proficient in astronomy, this is a rare event since the cultivation of the calendar during the Taizu period of this dynasty, so it is inevitable that all kinds of rumors will spread outside, because these rumors of unknown truth and falsehood have trespassed on my crown ceremony, questioned my teacher, and the emperor is too unpopular!" ”

He didn't care how people came in—whether they were instructed to come in by those people in the Lu Mansion who were not used to him, or whether they were instructed by his brother and sister-in-law; Or what kind of calculation does Daddy have, so he deliberately lets people break in; He doesn't even care what kind of arrangement Zhang Shou or even the emperor has - what he cares about is the attitude of the person who comes and doesn't take him seriously!

If you don't put Zhang Shou in your eyes, you don't put him in your eyes!

After drinking angrily, before the other party could regain his strength, he even said like a cannon: "My teacher is Dr. Guozi, who lectures in the East Palace, but he is humble and humble, and seconded the invitation of Yue Shanchang, suggesting that the emperor convene the world's arithmetic talents to gather in the capital to prepare for the rebuilding of the calendar, even if he has a proposal, it is also out of public heart, for the emperor to figure out for reference, what to cancel the leap month, I have not heard of it!" ”

Lu Sanlang, who was in denial, quickly glanced at Zhang Shou, thinking about canceling such a fatal thing as Leap Month, regardless of whether Zhang Shou really said it, he would help people block this article back first, otherwise don't talk about such people when he turns around, even the boss of the court will bombard.

"My Chinese arithmetic since the Xia, Shang and Zhou dynasties, famous scholars, countless classics, naturally unique in the world, and from the Spring and Autumn Qin and Han dynasties to the Wei, Jin, Southern and Northern Dynasties, this arithmetic has been constantly developing, but in the Sui and Tang dynasties, known as the Guozijian joined the arithmetic, and even the ten books of arithmetic were written, but in fact, they did not advance but retreated, until the Song and Yuan dynasties were very prosperous!"

When the little fat man talked about the rise, he unconsciously revealed some of Zhang Shou's previous remarks about his history of Chinese mathematics. And as soon as he said this, Ye Mengqiu, the round-faced young man who took the lead in breaking in, suddenly stopped.

The previous words were taught to him by a senior brother behind him, although he memorized it well, but because it did not fit his character, it was still a little awkward to say it, but at this time, Lu Sanlang said that Sui and Tang were not good at arithmetic, and he immediately blew up.

"The Sui Dynasty died in two generations, but there was also a famous algorithm Wang Xiaotong, and in the Tang Dynasty, not to mention the ten books of the King James Sutra, Wang Xiaotong entered the dynasty, and he and Li Chunfeng were all the most outstanding arithmetic masters!"

"Arithmetic, everyone's fart!" Lu Sanlang didn't care that the emperor was still sitting on it, his father, teachers, relatives and friends were there, and he was directly dirty, "Li Chunfeng is also forgotten, Wang Xiaotong said that Liu Hui of the Wei Dynasty 'was not Sinan, but he was also alone for a while', and said, "When the "Fixation Technique" was called exquisite, he did not realize that the techniques carried out by Fang Yi were all wrong, and between the pavilion and the square pavilion, it was not exhausted. ’”

"He even had the face to say, 'He Xun and Xu Yue's disciples, Wang Biao, Zhen Luan's generation, they will be heard of. However, there are still omissions in the old scriptures. Since Liu Hui and below, it is even more insignificant. 'Dare to love this world, he is the king of filial piety! He also said unashamedly that he 'delved into the mysteries and made all the songs.' There is no bosom friend in the generation, and eventually they will become widowed. 'Tsk, why didn't he say that he was the most powerful arithmetic master in the past! ”

"Oh, he has already said so, otherwise he would not have written a book of "The Book of Ancient Calculations", so he said triumphantly to the emperor, asking for someone to read it, and if he changed a word, he would be willing to pay a thousand gold...... I'm sorry, his "Ancient Arithmetic" deliberately shows off the difficulty, which is far less simple than "Nine Chapters of Arithmetic". If you can't understand the things of your predecessors, you denounce them as ridiculous, and I think it's him who is ridiculous! ”

The round-faced young man Ye Mengqiu was simply caught off guard by Lu Sanlang's words. He has never had much of a verbal fight with someone in his life, especially this kind of verbal war that derogates other people's character. Even if he admires Wang Xiaotong as him, he can't put all the quotations on his lips like Lu Sanlang - especially when people hate this kind of quotations, but they actually recite them like a stream, and he didn't expect it.

Although he also felt that if Lu Saburo hadn't fabricated quotations, Wang Xiaotong, a master of arithmetic in the early Tang Dynasty, was indeed a little too arrogant, but he couldn't help but say: "But Wang Xiaotong's twenty questions about the "Ancient Arithmetic", do you dare to claim that they can be solved?" ”

"Of course I can! If you don't believe it, just ask! As far as his contribution to arithmetic is concerned, he also deserves to say big things to show off? ”

Seeing the little fat man raise his eyebrows proudly, Zhang Shou couldn't help but be speechless. In order to be a good doctor of arithmetic in Jiuzhangtang, although he used a new textbook compiled by himself in the name of Ge Yong, in order to be a good doctor of the country, he also went to turn over the ten books of arithmetic. Although he was very dismissive of the arrogance of the mathematician Wang Xiaotong in the early Tang Dynasty, it was impossible for him to deny the contributions of others to mathematics.

What's more, Zu's "Fixation" is lost, but the "Ancient Calculation" is still there, and the twenty questions are not as simple as some of the questions in the nine chapters of arithmetic, but they will smash you with a stick as soon as they come up - Wang Xiaotong will show off his skills as soon as he comes up, and there are no simple questions suitable for ordinary people in the twenty questions! can use geometric normal equations, that is also Wang Xiaotong's first creation!

You must know that the first question of "The Ancient Calculations" is to find the equatorial longitude of the moon in the middle of the night! How many students who are good at high math can solve this thing? Lu Sanlang hasn't learned astronomy yet, how can he boast about this Haikou?

Next, Ye Mengqiu asked, Lu Sanlang answered, but Lu Sanlang's performance made him have to marvel, because Ye Mengqiu asked the first five questions of "The Ancient Calculation Sutra" in one breath, and Lu Sanlang actually explained Wang Xiaotong's solution to the problem.

In the face of the little fat man's confidence and posture, even he couldn't help touching his chin in surprise, but suddenly noticed that a gaze fell on his face.

He followed his line of sight, and saw that the emperor had a strange face, and Zhu Ying next to him was snickering, and he knew that the emperor must be angry and funny about Lu Sanlang's actions.

I want you teachers and students to screen these called talents, not to let you be in the limelight!

Lu Sanlang was indeed in the limelight at this moment, seeing that Ye Mengqiu had to jump to ask questions after the first five questions, he still answered calmly, until the round-faced young man stopped his mouth with a depressed face, and he smiled vividly.

"It is not surprising that people today are better than the ancients, but if people today are not as good as the ancients, it is a great shame! Because we eat better than the ancients and dress better than the ancients, if the things we have researched are not as good as the ancients, wouldn't we not be sorry for the good life we have now? ”

"As for the arithmetic value of small foreign countries, it is not worth learning...... Who doesn't know that my ancestor Ge Lao Taishi was most disgusted with those Arabic numerals back then? Even if Emperor Taizu started to implement it, he had used it all over the world for so many years, and it could be regarded as deeply rooted in the hearts of the people, but his old man had always been reluctant to use it at first, but once he found that those symbol systems were helpful for calculation, he immediately used them without thinking about it! ”

"Patriarch Ge not only used it, but also those Yuan books in the ancient and modern Tongji Library, those that were put on the shelf, it is said that they were translated by the people of the Yuan Dynasty from the foreign scriptures, but the books that were put on the shelf from the Yuan Dynasty to the present dynasty were also studied one by one!"

"Take the essence of the other and discard the dross of the other, this is the attitude of doing knowledge in a down-to-earth manner! Don't be superstitious about predecessors, don't despise small foreign countries, and go to the chaff, this is the attitude of life! Just want arithmetic to enter the homes of ordinary people, this is the attitude of being a teacher! ”

Even Liu Shilang of the Ministry of Works, who knows Lu Saburo very well, can't help but feel that this future son-in-law is really dazzling at this moment. If it weren't for the round-faced young man who couldn't say Lu Sanlang, he seemed to be angry and crying, if it weren't for the older people behind the people whose faces were gloomy one by one, he even thought that this was a drama arranged by the Lu family's father and son.

And seeing Lu Saburo's performance next, he finally further determined that this play was definitely not arranged!

Because, after Lu Sanlang casually answered Ye Mengqiu's full ten questions, he suddenly changed his words at the end of the answer and said: "This brother, you have questioned me for so long, is it time for me to ask you?" Since you are an arithmetic talent who is called to Beijing and is proficient in astronomy, you should be able to solve some simple questions. ”

The little fat man smiled like a smiling Maitreya Buddha, and even clapped his hands gently. However, with his clapping, there were two blank ...... Blackboard!

Ah Liu, who sent the blackboard, saw that Lu Saburo first stared at him with wide eyes, and then smiled, said thank you, and took the pen in his hand happily, and then strode forward and began to write on one of them. Seeing this, he quietly retreated—but instead of going out, he retreated directly to Zhang Shou's side to serve.

Faced with the tacit understanding between the two of them, Zhang Shou couldn't help but smile dumbly: "Ah Liu, in addition to reporting to Lu Sanlang, you also colluded with him in advance?" ”

"The teacher has something, isn't the disciple obeying him?" Ah Liu first said a serious sentence, and then added, "The disciple is in the limelight, and the teacher is even more in the limelight." ”

Zhang Shou suddenly sighed. Very good, this kid who has always seemed honest and honest in Rongshui Village is now getting darker and darker!

As for the others, at this time, I saw that Lu Saburo was brushing and writing all over the blackboard, all of which were full of symbols of dragons flying and phoenixes dancing, and there were almost no Chinese characters to be found, not to mention the feeling of doubting life at this time. Even Lu Xuan, who is the father, and Liu Shilang, who is the future father-in-law, can't help but rub their eyebrows at this moment.

In the future, you must remember that arithmetic, a field that little fat people are good at, don't mess with it...... Because I can't afford to mess with it!

When Ye Mengqiu saw Lu Sanlang, whose face was rounder than himself, throwing away the pen in a dashing manner, and then personally moved the blackboard in front of him, he couldn't help but blush. Sure enough, I saw Lu Sanlang clapping his hands next, and then smacked his mouth at the blackboard.

"Just now I answered the ten questions in the "Ancient Calculations", Wang Xiaotong's solution ideas, and the specific answers have also been said, of course, you can also think that I memorized it. And the current question is a question in the "Four Yuan Jade Jian". I know it's hard to solve it in three moments, so please explain to you on the spot how to use the quaternion technique to solve it. ”

Speaking of this, he showed a big smile: "If you can't do it, these people behind you can solve it!" ”
