The first court meeting after the winter solstice rest, this is also the last court meeting before the year, if there is no urgent military and political affairs, the next court meeting is the big court meeting after the beginning of the year.

Therefore, the atmosphere of this court meeting was relatively relaxed, and officials at all levels made a year-end summary, and everyone chatted with each other about some interesting things.

However, today, Zhao Xing implemented an unprecedented organizational plan and transferred about seven or eight people's job responsibilities, including Wang Jie, the host and guest of the Ministry of Rites, and Cong Rui, the supervisor of the Shaofu Supervisor. Although this arrangement is a bit abnormal, even the officials have not received any news, but it seems that this kind of transfer is the innocuous playfulness of Zhao Xing, the little emperor, just a flat adjustment of several departments, and the ministers think that it will be the end of the year, so they don't bother to bother with this easy-to-talk emperor anymore, let him play around.

After some chores were handled, everyone chatted for a while about the interesting things during the break, and the time was about the same, and the most photogenic in the stage of chatting about the interesting things was actually Song Beiyun, who was not even qualified to participate in the court meeting.

These people, if they seize the opportunity, they will definitely beat people like Song Beiyun, what imperial city envoys don't do their jobs, what six-grade officials take the lead in messing around, what Xiaohong chases the bull and laughs generously, and what fertile fields are extravagant and wasteful.

The entire court seemed to be in the Black Song Dynasty, and as soon as everyone mentioned him, there seemed to be a happy atmosphere in front of the palace.

But not everyone is so wanton ridicule, such as Zhang Shangshu of the Ministry of Industry, he has been standing in the corner and watching coldly, although because of his third son before, he also has some resentment of Song Beiyun in his heart, but later he also visited the big doctor, and the big doctor said that if Song Beiyun didn't pull the third child out of the sea of bitterness in time, the child would be wasted, so Zhang Shangshu has nothing to hold a grudge again.

As for Song Beiyun's jokes, he won't laugh like those people, as the secretary of the Ministry of Industry, he is a person who is proficient in arithmetic, Song Beiyun's question downstairs at the city gate, and his daughter at home has already been copied home word for word.

In those days, his daughter disappeared during the day, and sat at the table at night to meditate, this abnormality caused Zhang Shangshu's curiosity, he took a moment to find his daughter yesterday, and after seeing the full table of topics, he played with it for a while.

But I don't know if I don't see this, I saw that the old man fell into it at that time, isn't it the art of building a dam to irrigate the fertile land from a different angle? Isn't it the art of the battlefield that Xiaohong chases the bull, Zhang San and Li Si go in the opposite direction? And what Li Jia built a house for five days and then Huang Yi took over, and it also showed that Huang Yi's craftsmanship was not good, Li Jia did it for three days, and then Master Wang felt slow, so he asked the two of them to do it together, and asked the question of how many days it would take to build a house.

Some of those hundreds of questions have already been solved, but most of them are still unsolved, how can the old man endure this? I didn't sleep all night last night and did the problem there, and the more I did it, the more sober I became, and even now his mind is back and forth with frogs jumping into wells, Xiaohong chasing cows, Li Jia building houses, monkeys stealing melons and fertile fields irrigating water.

These questions are difficult, it is indeed not too difficult, but many ideas are eye-catching, as a person who can come up with so many interesting questions at one time, I think this Song Beiyun is also a master of arithmetic.

And Zhang Shangshu and the others still have to go to Song Beiyun in person when they get out of the court meeting, after all, he still has a few problems that he wants to test him. As a big man in arithmetic, of course, he can't laugh at arithmetic like those people, the only thing he can do is to keep his head down and not listen and not mix.

As for one person who has not been involved, that is Lord Ding, a high-level Qingliu player, Dali Temple, because before Song Beiyun, this person who opened his mouth to rule the country and closed his mouth to the king's law was the object of ridicule of those hideous and stinking people around him.

finally waited for the court meeting, Zhang Shangshu got out of the head, and even Zhao Xiang behind him didn't hear him calling, and ran to the Imperial City Division with his head stuffy.

Naturally, the people of the Imperial City Division did not dare to stop him, not to mention that he was one of the six Shangshu, you must know that this Imperial City Division was attached to the Ministry of Industry, and he was the nominal big boss.

"Where is Song Beiyun?"

He dragged a guard and asked, and the guard's face was ugly, because in his opinion, Zhang Shangshu was here to arrest his daughter, but it was not easy for him not to say anything when he encountered a big official to guide him, so he quickly ran out of the yamen after pointing to a room playfully.

Zhang Shangshu came to the outside of the room with his hands behind his back, pushed the door and walked in, but when he walked in, he didn't see Song Beiyun, but he saw his most favored little daughter lying in front of a table in the corner, crackling with an abacus, and while playing the abacus, he was still chanting words like "eight seven eight more than six, eight eight sixty-four" and so on.

There are also piles of manuscript paper on it, with symbols written on it that are difficult to understand. On top of the manuscript paper, there is also a small bound book, and Zhang Qing will turn it over from time to time when he is calculating.

Zhang Shangshu walked over, picked up the book and flipped through it a few times, his brows furrowed slightly, but before he could speak, his daughter shouted coquettishly: "Master...... It's too hard for me to figure it out. ”

Hearing her daughter's complaints, Zhang Shangshu looked over, but found that the paper under her hand was full of all kinds of strange symbols, like insects crawling.

"Ahem!"

Hearing this cough, the pencil in Zhang Qing's hand fell to the ground in fright, and then she quickly stood up and lowered her head with a well-behaved face: "Father...... How did you get here. ”

"I heard that you have been running to this imperial city all day long, just to see what you are doing."

After that, he walked to Song Beiyun's position and sat down, and began to flip through the book, there were many strange symbols on it, but there were notes under the symbols, such as what the X was for, what the cross was for, and there was even a set of ninety-nine multiplication tables and relatively complete triangles, trapezoids, cylindrical shapes, conical shapes, and circles in the back.

Who is Zhang Shangshu? When he was young, he was the first person to learn arithmetic, and he was immersed in this way in the Ministry of Industry all his life, but now when he sees this booklet, and then connects it with the strange symbols before him, he is inevitably shocked.

And this booklet not only uses mathematical methods, but also elaborates on the laws of physics, and many things are even unheard of by Zhang Shangshu.

"Qing girl."

"Daddy......" Zhang Qing lowered his head like a child who had done something wrong: "Will you return that book to me......?"

"What are you just doing?"

"Circumference."

"Fetch it." Zhang Shangshu twisted his beard and looked at the pi on it, squinting his eyes and looking at it carefully.

He may not be familiar with the others, but he is extremely proficient in that circumference, after the ancestor Chongzhi counted to seven, and more than thirty years ago, Zhang Shangshu had already counted this number to nineteen.

It's just that he didn't think it would work, so he didn't make any calculations. But now that he saw that his daughter was calculating this, he couldn't help but have some itchy hands, so in order to show off in front of his daughter, he decisively asked the child to take her calculation results.

"So much?"

"Hmm...... Division...... Master said that it should be reversed according to the formula. Zhang Qing put the stack of things pushed backwards in front of his father, and his expression was a little panicked: "I don't know if it's right or wrong, Master asked me to count it." ”

Zhang Shangshu didn't talk nonsense with his daughter, and began to look at her calculation results, and he really couldn't understand a lot of symbols on it, and he had to check the reference book next to him while reading, but the professional player is a professional player, and the mastery speed is much stronger than that of his daughter, who is a half-ass, and quickly understood the meaning of addition, subtraction, multiplication, division and root number, and then completely ignored the existence of his daughter and plunged into the ocean of mathematics.

"Master......"

Zhang Qing hurriedly ran to the dining hall and found Song Beiyun who was gnawing on a duck there, and Song Beiyun looked up at her: "Didn't you just finish eating?" ”

"My daddy is here......"

"Huh? Zhang Shangshu? Song Beiyun scratched his head: "What is he doing here?" ”

"I don't know." Miss Qing was also confused: "He didn't say anything." ”

"What is he doing now?"

"Do the ......"

Yes? A dignified scholar, come to the Imperial City Division to do the question? What kind of psychosis is this? But since he came, he couldn't drive people away, not to mention that he was a scholar, just the nominal head of the parent company of the Imperial City Division, Song Beiyun didn't have any reason to toss.

"He hasn't eaten yet, has he? You go to the dining hall and get some food for him. Song Beiyun pointed to the master chef who was cooking: "Let the master get some duck legs, meatballs and stewed mutton and send them over." ”

"Oh......"

Zhang Qing took the food and put it in the food box and sent it to Zhang Shangshu, while Song Beiyun was munching on the duck while thinking about how to tell Master Shangshu about his entry into the Ministry of Industry after the Spring Festival.

It is definitely impossible to step down as the Imperial City Division, and the Queen Mother's group will definitely not let them go, but it is unprecedented for them to want to enter the Ministry of Industry with a position here. In addition, his side has almost given all the power to Yan Shu, so I think Zhao Xiang will not be too embarrassed to be such a nobody.

On the other side, seeing Zhang Qing bringing the food, Zhang Shangshu just nodded, and then continued to bury his head in the calculation, listing formulas in his right hand and crackling in his left hand, and the speed of opening the bow left and right was so fast that it flew up.

Zhang Qing looked stupid, she had known her father for more than ten years, and she had never seen him so vigorous, thinking about her clumsy appearance and looking at her father's appearance as if he was going to beat the abacus on fire, it was really shocking.

"Easy to use......" Zhang Shangshu's stomach growled, he also put down the pen, pressed the things under his head with a paperweight, picked up the rice bowl and ate it, and after eating two bites, he looked up and asked Zhang Qing: "You learned these things in the Imperial City Division?" ”
