In fact, Yun Xiao is somewhat self-indulgent, looking at the sixteen-year-old general of the Han Dynasty, except for the Liu clan's ancestor Yun Xiao is the only one, it can be seen how Liu Qi favors Yun Xiao, it is rumored that when His Majesty was eating at the Yun family, Yun Hou's leopard lifted the table of His Majesty Xi à Queen Mother Liang Wang, His Majesty Xi à and the Queen Mother did not surrender, and it can be seen that the grace is long.

When it comes to knighthood, he is also a marquis. It is not too much to say that it is a young hero, who doesn't know that the wealth of the Yun family Zhuangzi is full of Chang'an. In fact, some noble families in Chang'an City, and even the Liu clan have begun to consider telling their daughter-to-be to Yun Xiao, if Yun Xiao is not out on the expedition, I am afraid that the person who said the matchmaker has already broken through the threshold.

The five brothers-in-law are obviously Dong Zhongshu's party, and they all have a hostile attitude towards Yunxiao. As soon as the banquet was set, the brother-in-law came out to stir up trouble.

"I heard that Yun Xiao knows a lot about my Confucianism, Yan Ruxin asked Yun Hou for advice......"

"If you are hard, you must not be rude. Yunhou is a distinguished guest of the Yan family, how can you be so rude, have you forgotten the family motto of the Yan family? ”

"Father, the child doesn't dare to forget the family motto of the Yan family, but what you just said is related to the lifelong event of the little sister, and the child just wants to take the school entrance examination Yunhou."

When Yun Xiao heard about the major events of his life, his eyes suddenly lit up. No wonder the old man invited himself to dinner, it turned out that he was going to propose, God, if he really wanted to sleep, someone handed him a pillow. If it weren't for the occasional restrictions, Yun Xiao really wanted to rush up and hug Yan Qing and kiss him.

"Okay. Yunhou, and the old man Rong said a few words. The old man heard that Yunhou had not yet decided to marry, and the old man had three daughters under his knees, and two of the daughters had already married into wives, only the young daughter Xian'er served beside him, and she was sixteen years old and Yunhou was also considered to be the same age. I don't dare to say that I am regarded as a pearl in my palm, but I also love it. is old and decayed, and intends to marry the little girl to Yunhou. I don't know what Yunhou wants? ”

Yun Xiaole almost didn't faint, it was really a wedding banquet.

"The younger generation has loved Miss Yan for a long time, and I originally planned to propose marriage today. Now it seems that the younger generation is rude. ”

"Hahaha, but the old man, this unsuccessful son, still has to take the school for you. I don't know if Yunhou can give advice, so that they have nothing to say. ”

"The Yan family has a family history, which is also a natural reason."

Hmph, Lao Tzu went to 985 in college, and 211 passed me with your little knowledge reserve. The occasional father is a professor of the Chinese Department of Peking University, and when it comes to family history, Lao Tzu is probably not inferior to you.

"Zi said, a gentleman has six arts. The first four items are not suitable for today's competition. However, this book and the number can be taught by Yunhou. ”

Hearing Yan Ruxin's words, Yun Xiao's regretful intestines turned blue. At the beginning, my father watched himself practice calligraphy, why didn't he practice calligraphy well? Don't talk about calligraphy, even if it's a fountain pen, you can practice well with Pang Zhonghua. Compared with what calligraphy, there is originally a keyboard compared with Lao Tzu, Sogou full spelling five strokes as you choose.

Fortunately, the competition is between books and mathematics, how can I say that I will not lose to the ancients more than 2,000 years ago in mathematics. But from kindergarten to high school, I never scored 90 points in math.

Several of Yan Ruxin's disciples brought over a roll of coarse cloth, on which nine squares were drawn three horizontally and three vertically.

Yun Xiao secretly said that he would not be interested in the Nine Palaces.

Sure enough, Yan Ruxin picked up the brush, dipped it in ink, and wrote a big five-character on the middle grid.

Yun Xiao covered his mouth and snickered, this thing was taught by his elementary school teacher.

"Please fill in the grid from one to nine, and you can't repeat it. Whether horizontally or vertically, the sum must be fifteen. Please, Yunhou. ”

Yan Ruxin bowed his hand to Yun Xiao with a smug face. He has studied this nine-square grid for many years, and he has some experience. Moreover, people who do not have a certain arithmetic foundation in this nine-square grid cannot be calculated.

Yun Xiao smiled slightly, wearing nine shoes and one, three on the left and seven on the right, two or four for the shoulder, and six or eight for the foot. The mantra that will be memorized in the first grade of primary school is more slippery than the back of the ninety-nine multiplication table.

Yun Xiao stepped forward and began to write without the slightest pause.

Yan Ruxin looked at Yun Xiao's barely thinking writing, and was suddenly speechless. This nine-palace diagram is the result of several years of research by himself, how could Yun Xiao fill it out without thinking. Yan Ruxin was still shocked, Yun Xiao had already filled in.

"Mr. Yan, how's it going?"

"You ......"

Yan Ruxin pointed at Yun Xiao's head and shook his hands, as if he had seen a ghost.

"Come and don't be rude, Yun Xiao also wants to discuss arithmetic with Mr. Yan. I wonder if Mr. Yan is not stingy in teaching? ”

Yan Ruxin took a long time to recover, and arched his hand at Yun Xiao and said, "I don't know how Yunhou wants to take the school Yan." ”

Yun Xiao picked up the pottery bowl, drained the wine inside in one gulp, and said, "A ruler calculates how many cups of wine can be poured into this jar." How is it? ”

"Uh...... This ......" Yan Ruxin was dumbfounded, how can this be calculated.

Yun Xiao patted the cylindrical wine jar and smiled proudly, for some reason the Yan family's wine jar was actually cylindrical, and there was no bulging belly at all. Calculating the volume of such a cylinder is simply too easy, and the volume of the wine bowl is a little more difficult, but it is also difficult to overcome the clouds. Lao Tzu has passed the college entrance examination, and there is no reason why he can't calculate the volume of this wine bowl. It's good to divide by two, it's not difficult.

"Yan admits defeat, I don't know how Yunhou calculated."

Yan Ruxin couldn't imagine that a ruler could calculate how many bowls of wine could be poured out of the jar. If so, then wouldn't all rivers, lakes and seas be measurable?

Yun Xiao carefully measured the circumference of the jar, and then measured the diameter. Picked up the pen and counted on a piece of paper handed over by Canghu, Yan Ruxin was going to steal the teacher, but when he wanted to take a closer look, his eyes were full of strange words that he had never seen. Sketching and painting a large article. When Yun Xiao finished calculating the last number, he said confidently: "If you don't count the part spilled when pouring the wine, this jar of wine can pour forty-seven and a half glasses." Mr. Yan, would you like to give it a try? ”

Dong Zhongshu hurriedly called for someone to take out all the bowls at home, and Yun Xiao hurriedly stopped it with a smile.

"No, just take an empty jar."

Dong Zhongshu was stunned, and then understood what Yun Xiao meant. I couldn't help but blush, poured it out in the jar, and then poured it into another empty jar, why didn't I even think of such a simple thing.

In full view of everyone, the wine glasses were poured out one by one, and then the cups were poured into the empty jar. Canghu poured it very carefully, and not a drop of wine was spilled outside. When everyone counted to forty-seven, Canghu shook the jar and found that there was only some residual wine in it, which was indeed less than a bowl. Immediately admired his master, and carefully poured out the residual wine. When the last drop of wine poured into the bowl, everyone was amazed.

"Yun Hou, Yan admires this arithmetic all the way, just this arithmetic Yun brother can already be called the grandmaster level. This calligraphy is not comparable. Brother Yun's unpredictable arithmetic alone is enough to marry my little sister. ”

Yan Ruxin is obsessed with arithmetic, and admires the strong man of arithmetic the most. Now seeing Yun Xiao's unpredictable skills, he was suddenly shocked that the heavens had completely forgotten Dong Zhongshu's entrustment.

Yun Xiao saw that Yan Ruxin was so knowledgeable, and generously copied the two sets of formulas, and gave them to Yan Ruxin, which made Yan Ruxin excited and inexplicably increased his good impression of Yun Xiao, and immediately became obsessed with research.

Take a ruler and measure everywhere, and then start calculating constantly, from the bowl to the pillar.

Dong Zhongshu was discouraged, and originally expected Yan Ruxin to come out to take the school entrance examination Yunxiao, and then stir up the marriage, but Yan Ruxin, who had been obsessed with arithmetic all his life, was actually defeated by Yunxiao. Not only did it not play a role in combating Yunxiao, but I am afraid that the junior sister who is peeking behind the screen now also admires this kid even more.

must compare the next calligraphy, how to say that he is also a little experience, he must compare this Yunxiao, otherwise the junior sister will really marry the Yun family's wife.

"Yunhou's arithmetic is indeed unpredictable, presumably this calligraphy is also a master, Dong Mou's skills are itchy. I wonder if Yunhou can give advice? ”

Yan Xian outside the window carefully recalled the four words and smiled to herself. Suddenly, I felt some strange noise behind me, and turned around to look......
