Chapter 7, chickens and rabbits in the same cage.
"Okay, okay, Wen Ruo don't say anything more." Mrs. Wang waved her hand, and when she saw it today, she lived up to her reputation. No wonder even Xun Shuang couldn't win him, she was afraid that Xun Yu, who had always been bad at arguing, would get angry and suffer internal injuries, so she hurriedly stopped her.
Xun Jiang grimaced, provoking Xun Yu, whose chest was rising and falling sharply.
"Jiang'er, how about the old body want to send you to Yingchuan Academy?" Old Madam Wang said it bluntly.
"Yingchuan Academy? No, no, no! Xun Jiang shook his head violently, he didn't want to go to school.
"Jiang'er, the gentleman of Yingchuan Academy is a strange person, if you study diligently, you will definitely be able to shine on the lintel in the future!" Old Madam Wang patiently persuaded.
"Sister-in-law, no one in this world can teach me for a long time! Don't waste your tongue! "Where would the highly educated Xunjiang still want to listen to the chatter of those old scholars.
"Jiang'er! Don't look at the top, although you are talented and intelligent, don't underestimate the heroes of the world! You must know that there are people outside the world, and there is a sky outside the sky! "Old Madam Wang saw that this was terrible, such a good seedling should not be delayed because of arrogance.
Xun Jiang was a little irritated when he listened, he felt like the generation gap that he listened to his parents in modern times. You know what the other person is saying, but the other person doesn't know what you're talking about.
"Okay, isn't my eldest nephew a top student in the academy? If he can solve it in less than twenty breaths, what shall I do? If he can't solve it within twenty breaths, it proves that the gentleman of the academy is nothing more than that, and the sister-in-law should not mention it again! Xun Jiang waved his hand and said.
"This..."Old Madam Wang looked at Xun Yu.
Xun Yu is quite confident in his knowledge, his robe waved casually, his eyebrows are full of confidence, and he said a word with action: come!
"Chickens and rabbits are in the same cage, with forty heads and one hundred and ten legs. How many chickens and rabbits are there? The timer begins! ”
Xun Jiang's title made Xun Yu stunned, he thought it was from "Zuo Chuan" and "Liutao", no matter how advanced and profound, it had to be military theory or something, but he didn't expect this kind of question.
Twenty breaths passed quickly, and Rao didn't work out it after all his efforts.
"Well, you can't even guess such a simple question. It seems that the academy is nothing more than that! Xun Jiang glanced at Xun Yu, who was still mentally arithmetic, and shook his head and said. This modern mathematics is not something that can be easily solved by those who don't know how to do the rest of the formulas in ancient times.
"What is this? No one in the world can untie it in twenty breaths! Xun Yu said unconvinced, if he was giving him a cup of tea, he would have the confidence to untie it.
"No one? Then you come out, if I can't untie it in ten breaths, I will go to the academy obediently immediately. Xun Jiang glanced at Xun Yu and said.
"Chickens and rabbits in the same cage, sixty heads, one hundred and seventy-six legs. Why? Guo Jia said on the side. As soon as he heard the question, he knew that Xun Yu would never be able to solve it within twenty breaths, so he had already come up with the question and was ready to take the test for Xunjiang.
"Twenty-eight rabbits, thirty-two chickens." Xun Jiang said it within three breaths.
Guo Jia's eyes were full of horror, he used thirty breaths to solve the question, and Xun Jiang solved it in three breaths.
Seeing Guo Jia like this, Xun Yu naturally knew that Xun Jiang was right.
"Sister-in-law, do you have anything to say? If there really is a mountain outside the mountain, a sky outside the sky, then I am already a mountain outside the mountain, a sky outside the sky! Xun Jiang was simply crazy, but Old Man Wang couldn't refute it.
Didn't you see that Wen Ruo was shaking his head and sighing? Guo Jia, who is known as Victory and Wenruo, stared at eyes the size of an egg at this time, what else did she say?
"How did you figure it out?" Guo Jia grabbed Xun Jiang's arm, his eyes full of shock, and asked.
"Chicken legs lift two feet, one hundred and seventy-six minus one hundred and twenty and fifty-six legs remain, there are no chicken legs left in the cage, fifty-six divided by two equals twenty-eight is a rabbit!" X.Y was too complicated, and Xun Jiang was afraid that they wouldn't understand, so he said a simple solution.
"Divide by two? What is this algorithm? Guo Jia was stunned.
"Look, you don't even know how to do algorithms, and you're asking me what I'm doing? Hurry back and rest, I still have many ladies to take care of! Xun Jiang waved his hand and walked outside, he didn't bother to say more, it was too troublesome to say.
"Brother Xian, wait for me!" Guo Jia chased out with red eyes, he couldn't let go of such a mastery. He vaguely felt that Xunjiang's method, if used in military politics, might be twice as effective with half the effort, or even dozens of times as effective as the current algorithm.
Xun Yu also wanted to chase after him, but his face was a little hesitant.
"The capable are teachers, what are you waiting for?" Old Madam Wang smiled and said.
"Yes. The boy went! Xun Yu hurriedly chased after him.
Looking at their departing backs, Old Madam Wang suddenly laughed.
"In less than ten years, Xun's will be a blockbuster! The old body can finally let go of the burden! Mrs. Wang said with a smile, her eyes full of relief.
"Pass the order, from today onwards, no one will be allowed to disobey Xun Jiang's words! The status of Fuzhong is equal to that of Wenruo! ”
"Yes."
…………………………
The courtyard of Xunjiang is very lively.
"Sisters-in-law, all of them look like immortals, with ice muscles and jade bones, and they are all over the country and the city!"
Xun Yu looked at Guo Jia a little speechless and flattered there holding the baby flower, he really couldn't say these words.
"Okay, okay, you don't bother around here. If you want to learn, you can! Xun Jiang also defeated Guo Jia.
Guo Jia hurriedly put down the "sister-in-law" and sat next to Xun Jiang.
"Go and rest, and come in a moment for the sake of your husband." Xun Jiang said with a "flying kiss" to the girls.
"Okay, husband, come quickly! I'd like to hear the story from last time. ”
"I want to hear the Big Stupid Bear story too!"
"Nope! I'm going to listen to the last time, I haven't finished listening to it yet! ”
"I want to hear the story of Big Dumb Bear!"
"Okay, I'll say both of them in a minute!" Xun Jiang suddenly found that there were more "ladies" and he was really tired, but now it is still like this, and he will pay it back in the future.
"That's enough, don't add it for now." Xun Jiang thought in his heart.
After they all entered the room, Guo Jia couldn't wait to say, "Please also ask the virtuous brother to teach each other!" ”
"This algorithm was taught by a strange person I met at the beginning, and it is not impossible to teach you, but I have one condition!" Xun Jiang thought for a while and said.
"On what terms?" Guo Jia and Xun Yu did not dare to agree easily.
"I haven't thought about it yet, if I think about it in the future, how about telling you?" Xun Jiang naturally knew that these two would be big men in the future, and at most they would be a little clever and have the advantage of history. In the future, if there is something really difficult to do, it is inevitable that they will need their help.
"Good! As long as you don't commit adultery, you're done! Guo Jia responded.
"What about Wen Ruo?" Xun Jiang looked at Xun Yu.
"It's the same as being filial piety." Xun Yu also responded, after all, who knows what will happen in the future? And there is also a premise that you can't be a traitor.
"Okay, pen and ink are waiting!" Xun Jiang shouted.
Jiang Yi and the others looked at each other, Xun Jiang usually used these, and there was not a pen in the entire courtyard!
The scene was a little quiet for a while.
"I'll go get it." Xiaoliu was still clever and hurriedly ran out.
After a while, Xiao Liu took the pen and ink and a blank roll of bamboo slips. At this time, although there is paper, it is not easy to keep, and the price is too expensive. Ordinary people can't afford to use it at all, and it is not as cost-effective as bamboo slips.
