It is said that people become old and good, and today's Zheng Xuan is definitely worthy of the title of old goblin. The pen "Fun" Pavilion www.biquge.info has lived for more than 70 years, and what else has not been seen? Therefore, as soon as Gao Ye spoke, the little Jiujiu in his heart, what else was not clear about Zheng Xuan? Gao Ye also thought about knocking on the side while being kind and seducing, so that Zheng Xuan would follow his words, and then he would naturally feel that Yingchuan Academy was a good place. It's just that Gao Ye didn't think about it, he had just made a start, and when he asked him about his plans after arriving in Yingdu, his true purpose was debunked by Zheng Xuan.

However, Zheng Xuan at this time, even debunked and ridiculed, perhaps because of the old disrespect, these four words are Gao Ye's true evaluation of Zheng Xuan in his heart now. But in the end, Gao Ye has also been in this world for thirty years, even if the cunning is exposed, there is nothing to be embarrassed about. Instead, he looked jubilant, and said with a happy face: "Originally, I didn't know how to persuade Kang Chenggong to come to Yingchuan Academy, so that my father-in-law's wish could be fulfilled." I didn't expect Kang Chenggong to have the intention of going to Yingchuan Academy, so lucky, it is even more of a blessing to the academy! ”

When Zheng Xuan heard this, he immediately laughed and said: "You kid will climb along the pole, when did the old man say that I intend to go to that Yingchuan Academy?" I also have dozens of students here, how can I give up. ”

"Whatever is this, those who have learned something, can be outstanding. If you still need to continue to work hard, Kang Chenggong, you can just bring it to Yingchuan Academy. You see, where there are not only Ciming Gong, but also great Confucians like my father-in-law, as well as the Dongguan collection in the library and my private collection. There are also non-math students who can learn from each other with Kang Chenggong's students. As the saying goes, 'the stones of other mountains can be used to attack jade', Yingchuan Academy is a good place to go......"

"I heard that you studied under the Zongheng family?" Zheng Xuan's topic suddenly changed, and Gao Ye, who was still touting the academy, was stunned. The topic changed so quickly that even I couldn't react to it. But he replied respectfully, "Exactly." ”

"No wonder there is a clever tongue like a spring, haha, this rhetoric, if it was twenty years ago, the old man might really be moved." Zheng Xuan smiled and said, "I also heard that you are also lecturing in the academy?" ”

"Exactly, the younger generation teaches arithmetic in the academy."

"Hey, when the old man was young, he also studied the "Nine Chapters of Arithmetic" in Taixue. The old man has already heard that you are unparalleled in the world of high night arithmetic, and I also encountered an arithmetic problem a few years ago, and I have not been able to solve it. ”

"I want to hear about it." At this time, Gao Ye suddenly felt happy in his heart, this Zheng Xuan was so obsessed with learning, he really wanted to fool him to Yingchuan Academy, and he had to rely on the road of learning. As long as he asks for something, he is not afraid that he will not be able to move him. Isn't it just to solve a math problem, and a doctoral student in the 21st century will still be stumped by the elementary mathematics of the Han Dynasty?

When Zheng Xuan heard this, he nodded and said, "This question is like this, Mingxi, you listen well." Seeing that Gao Ye nodded, he immediately spoke: "Today, there are nine embankments to look at, there are nine trees on the embankment, nine branches on the wood, nine nests on the branches, nine birds on the nest, nine chicks on the birds, nine feathers on the youngsters, and nine colors on the hairs." Ask each geometry, the total geometry? ”

Gao Ye couldn't help but be stunned when he heard this, sure enough, a university scholar like Zheng Xuan is indeed not ordinary. I remember that when I was in Cai Yong's Mansion and fought with a group of children from the family, their questions were at most the level of junior high school students, but I didn't expect Zheng Xuan to open his mouth, which was a problem of proportional numbers. However, the ratio sequence has long been a rotten problem for me, so what's so difficult?

Before he opened his mouth, Zheng Xuan replied first: "The old man is exhausted in this question, but unfortunately, he only counts that there are nine embankments, eighty-one trees, seven hundred and twenty-nine branches, and six thousand five hundred and sixty-one nests. Although it is nine times every time, and the problem can be solved, the old man feels that there must be skills to be found in this problem. It's a pity that the old man has been thinking about it for a long time, but he has never had an answer. ”

Gao Ye laughed when he heard this: "Kang Chenggong, this question will not be solved for a while. Not only me, but anyone in the academy who has read my collection of arithmetic books can easily solve this problem. It's just that the numbers are too big, I need to use pen and ink, and I ask Kang Chenggong not to mind. ”

"What did you say?" Zheng Xuan, who had been laughing and scolding since just now, or who was calm, showed a surprised expression for the first time at this moment, and Gao Ye felt that Zheng Xuan was really taken aback at this time. Also, he thought about the topic for several years, but he didn't expect someone to solve it earlier, and he also wrote a book to say, how could Zheng Xuan not be surprised?

Seeing Gao Ye writing and drawing on paper, the most terrible thing was that Zheng Xuan couldn't understand what Gao Ye was writing at all. After about a stick of incense, Gao Ye replied: "The total number should be five million three hundred and eighty thousand eight hundred and forty ......" He said, and told Zheng Xuan how much each thing was.

Zheng Xuan looked at Gao Ye's operation, and said in amazement: "Mingxi, what are you writing here, why can't I understand it at all?" ”

"This is a new method of arithmetic...... Gao Ye said, and gave Zheng Xuan a brief introduction to the Arabic numerals, and then said with a smile: "I have done a lot of arithmetic books, and the "Nine Chapters of Arithmetic" is just the most rudimentary. If Kang Chenggong wants to see some advanced problems, he only needs to go to the academy to take a look. ”

"Haha, you kid, until this time, didn't forget to say that I went to Yingchuan Academy?"

"Hehe, Confucius Youyun 'Hearing the Tao, you can die at night', Kang Chenggong, are you really not moved? Besides, in Qingzhou, the big war is imminent, and it is good for Kang Chenggong to go to Yingchuan to avoid military disasters. ”

Hearing this, Zheng Xuan glanced at Gao Ye carefully, and then said solemnly: "I heard that you put all your books in the library of the academy and let the students borrow them. Although I have never studied in your discipline, I know a little bit about the rules of your discipline. Each generation only accepts two disciples, and grants all kinds of knowledge in the door, and the last two disciples, the winner can inherit the master. But why are you now making your knowledge known to the people of the world? ”

"Haha, learning is to learn to ask, and it is not a good thing to cherish yourself. Especially the matter of sibling rivalry, I am most dissatisfied. There is a saying in the "Book of Songs", "Brothers are on the wall, and they are insulted outside", what is the matter with fighting in the nest? This rule is long overdue! Gao Ye said this, and said with a sly smile: "Fortunately, my master died early, and there were only two people, Feng Xiao and me, plus Feng Xiao was still young, so I had the opportunity to change the door rules without any pressure." Now that he is the same brother and sister, what's wrong with Feng Xiaoqing? ”

"Haha, you're being honest." Zheng Xuan laughed when he heard this: "If your master knows everything, I see, he has to settle accounts with you!" But what you said is right, learning is such a thing, you can't cherish yourself with a broom, you must communicate more, so that you can grow. ”

What Kang Chenggong said is that this is why Yingchuan Academy is now reviving the hundred schools of thought, so that everyone has the opportunity to understand, dabble, absorb knowledge, and broaden their minds and horizons. After all, there are a thousand rivers, and they will eventually enter the sea. There are thousands of ways to learn, and different paths lead to the same end. ”

Zheng Xuan nodded, but he didn't answer Gao Ye's words immediately, but instead called his subordinates: "Go, call Zini to me." The next person went in a hurry, and Zheng Xuan looked at Gao Ye and said, "You are young, and you have such a heart, it is not easy." Yingchuan Academy, the old man really wants to take a good look now! ”

"If Kang Chenggong can give a lecture in the academy, it will be a great blessing for my academy!" Gao Ye solemnly arched his hand.

Zheng Xuan nodded, but did not speak, but closed his eyes, looking thoughtful. Gao Ye naturally didn't dare to disturb. It wasn't until a middle-aged man slowly entered, saluted respectfully to Zheng Xuan, and said, "Disciple meets the teacher," that Zheng Xuan opened his eyes. Then he said: "This is the five original Gao Mingxi, Zi Ni will see you first." When the man heard this, he immediately saluted Gao Ye, and Gao Ye saw that this person was older than himself, so he hurriedly got up and returned the salute. Zheng Xuan pointed to this person and introduced to Gao Ye: "This person is my disciple Guoyuan, the cousin Zini. ”

Gao Ye was taken aback when he heard this, shouldn't this Guoyuan be taking refuge in Liaodong at this time, how could he appear here? However, since Zheng Xuan introduced him to himself, he thought that there was only one purpose, that is, to let Guoyuan become a leader. This person may not be well-known in "Romance of the Three Kingdoms", but in history, he is deeply relied on by Cao Cao. Ranked in Jiuqing, he is even more dedicated, advancing and retreating, and he is really a talent of the country!

Therefore, Gao Ye immediately saluted respectfully: "I didn't expect it to be Mr. Le'an Zini in person, and I heard that Mr. Zini avoided trouble in Liaodong early at night, but I didn't expect to be able to see it today, it's really an honor!" ”

Guo Yuan glanced at Gao Ye in surprise when he heard this, after all, not many people knew about his avoidance of Liaodong, and even his teacher only told him when he came back this time. Unexpectedly, Gao Ye not only knew his origin, but even heard that he went to Liaodong, could it be that the teacher told him? But as long as Zheng Xuan was also puzzled, Guoyuan immediately denied this idea. Then he replied: "Don't dare, General Hou is now famous all over the world, and Yuan is fortunate to see it today, and he is also happy." It's just that, how did General Hou know that I had been to Liaodong? Guo Yuan couldn't help but be curious.

When Gao Ye heard this, he didn't know how to answer for a while, so he could only make up a random reason, and said with a smile: "Ye's subordinates have both caravans and Yingchuan Chamber of Commerce, and I also heard them talk by chance, saying that there are several great talents in Liaodong, and then I learned that Mr. Guoyuan was in Liaodong." It's really a happy event to meet in Qingzhou today, but I don't know if Mr. Guan Ning and Mr. Bing Yuan are good in Liaodong now? ”

Guo Yuan was shocked when he heard this, and then looked at Gao Ye carefully, and then said with a smile: "The two junior brothers are quite good now. ”

Zheng Xuan, who was on the side, smiled at this time: "Zini, I have the intention to go to Yingchuan this time and stay in Yingchuan Academy temporarily." These unsuccessful juniors and disciples of yours will also walk with me. Speaking of this, he immediately looked at Gao Ye and said: "Mingxi, Guozini has the talent of a countryman, can Mingxi be interested?" ”

Gao Ye immediately laughed when he heard this: "If you can get Zini's help and pacify Qingzhou, it will be easy!" If possible, I hope that Kang Chenggong will help him, and it is only right to recommend a few more talents like Zini as officials! ”
