After a while, Chang Lu asked Lin Yun, "Did you research this solution?"
Lin Yun shook his head and said, "No, I read it from a book."
Chang Lu hurriedly asked, "Where is the book?"
"Lost."
As soon as Chang Lu heard that it was lost, he immediately cursed bitterly: "You ignorant boy, how can you lose such a wonderful book so easily."
A scholar asked: "Chairman, chickens and rabbits can't understand human speech, how can they lift their feet?"
Chang Lu scolded: "Fool, that's just an analogy. Lin Shizi wants to tell everyone that first remove forty feet according to the number of heads, and the rest are all rabbit's feet, and then divide by two, that is If the number of rabbits is reversed in this way, the number of chickens will also come out.”
Ding Yuannan clapped and exclaimed: "I see, Lin Tonghuang really thought of a good and interesting solution. With this solution, there will be similar arithmetic problems in the future. It can be easily solved."
Changlu: "That's right."
After finishing speaking, he asked Lin Yun again: "Today, there are pheasant and rabbits in the same cage. There are 35 heads on the top and 94 feet on the bottom. How many are the pheasants and rabbits?"
Lin Yun thought for a while and said, "There are 23 chickens and [-] rabbits."
Ding Yuannan smiled and said: "I figured it out too, Lin Tongtong's answer is completely correct."
Ning Yue also said happily: "Master, I have also solved it, and this problem will not be difficult in the future."

Only now did Lin Yun notice this young man named Ning Yue. He was a little older than himself, with a slender figure and an appearance comparable to that of Jia Lian. He was a typical handsome man.
As if noticing that Lin Yun was looking at him, Ning Yue turned her head and smiled at him.
Just when Lin Yun was curious about this Ning Yue, Chang Lu came over and smiled at him and said, "Lin Shizi, I still have a problem here, you can try to solve it."
"will not."
Before Lin Yun could wait for Chang Lu to ask the question, he flatly rejected the other party's question.He was very unhappy with this fat head, and he was not in the mood to satisfy the other party's inquiry psychology.
Chang Lu was not annoyed after being rejected by him, but said cheerfully: "If you can solve this problem, I can let you use the quilt you brought."
Lin Yun was overjoyed when he heard the words, and he hurriedly said, "Mr. please come up with a question."
Changlu: "Today there is a wall five feet thick, and two rats wear it opposite each other. Rats are one foot a day, and mice are also one foot a day. Rats double every day, and mice half a day. May I ask when we will meet each other, and how much will each wear? "
Lin Yun thought: "Isn't this a topic in Chapter Nine of Arithmetic? Is this guy trying to test whether I have read Chapter Nine of Arithmetic?"
He picked up the brush, wrote and drew on the manuscript paper, put down the brush quickly, and said with a smile: "The answer is that the rats met in two days, two hours, 49 minutes and 52 seconds. The rats penetrated the wall three feet, four inches and seven minutes." , A mouse penetrates a wall one foot, five inches and three minutes."
As soon as Lin Yun's words fell, Ding Yuannan clapped his hands and praised: "It's not bad, Lin Shizi must have read the Nine Chapters of Arithmetic, right?"
Lin Yun nodded and said, "I didn't read it carefully, I just flipped through it casually."
Holding the manuscript paper written by Lin Yun, Chang Lu felt as if boiling water was bubbling in his heart. This little guy actually solved the obscure nine-chapter arithmetic problem with such a concise formula. This is clearly an arithmetic genius.
Thinking that he might have discovered an arithmetic genius, the old man's cheeks flushed with excitement, and he wished he could run immediately to tell the good news to Shan Zhang Lu Xingzhi.
However, after all, he suppressed the impulse in his heart and began to teach the scholars.
Lin Yun listened attentively, and what Chang Lu said was mostly arithmetic problems in elementary school. In this age when arithmetic is not very important, it is already very difficult to teach these things.
Although he was not interested in the content of Changlu's lectures, Lin Yun still listened carefully. He felt that the things taught by Yichen Academy were a hundred times better than learning those classics. honourable.

In the elegant room of Lu Xingzhi, the mountain is long,
After taking Lu Xingzhi's pulse, the old genius doctor advised him while writing the prescription: "It's okay, you have an old stomach problem and can't stand the cold, I advise you to build a warm kang in the house."

Lu Xingzhi shook his head and said, "Scholars and lecturers are all like this, so why am I an exception?"
"Aren't you asking for trouble for yourself?"
Lu Xingzhi smiled and didn't take up the topic again.
After a while, he asked again: "Old genius doctor, I heard that Lin Ruhai's nephew is going to marry that girl from the Qin family? Is this what you arranged?"
The old genius doctor nodded and said: "This old man came to Beijing this time for this purpose. Now that the marriage between Boy Yun and that girl has been settled, I can feel at ease."
Lu Xingzhi smiled and said, "You guys have missed that kid's future by making such an arrangement."
The old genius doctor smiled wryly and said: "I was forced to have no choice but to make such a bad plan. Besides, Kid Yun has no interest in official career, so it would be good to make him a rich man in the future."
Lu Xingzhi shook his head and said, "Don't you hear that the awl is in the bag, and you can see it at the end?"
The old genius doctor said suspiciously: "If the Son of Heaven refuses to use it, how can he stand out?"
Lu Xingzhi: "Today, today's son is a person who cherishes talents. It would be good if Boy Yun had no talent. If he is really talented, he will definitely be in a dilemma for His Majesty in the future. Whether he uses it or not, it will make His Majesty embarrassed. This is what the old genius doctor said today. too."
The old miracle doctor hurriedly said: "When this matter is over, I will take Yun boy back to Yangzhou, and the situation you are worried about will definitely not happen."
Lu Xingzhi laughed and said, "From what you said, I can tell that that little guy must not be an ordinary person."
As soon as he finished speaking, Chang Lu hurriedly opened the door and ran in, and said to Lu Xingzhi in surprise, "Shan Zhang, I found an arithmetic genius."
Lu Xingzhi smiled and said, "Chang Lu, you're not talking about that little fellow Lin Yun, are you?"
Changlu clapped his hands and said with a smile: "Captain Shan, you are right. I am talking about Lin Ruhai's nephew. His talent in arithmetic is more than a hundred times better than mine."
"Oh."
Lu Xingzhi was stunned by Chang Lu's words. He was very clear about Chang Lu's accomplishments in arithmetic. Now he said that Lin Yun was a hundred times stronger than him, which is too surprising.
Chang Lu: "Master Shan, I would like to recommend Lin Yun to be the lecturer of the academy, teaching arithmetic. What do you think?"
The old genius doctor interjected and said, "This is absolutely impossible. Boy Yun is most annoyed by these mundane tasks. Even if you ask him to be the head of the mountain, he will definitely not agree."
Lu Xingzhi: "Listen to the old genius doctor, don't force it."
"Ok."

Chapter 74: Lu Xingzhi's Means
After the arithmetic class, Lin Yun was surrounded by scholars, and everyone asked him for methods and skills to solve problems.
Lin Yun never refused anyone who came, and patiently answered questions for everyone until the bell rang and the second class began again.
The second class was to teach classics and righteousness. The lecturer was an old Hanlin named Li Fu. While taking notes, Lin Yun wondered in his heart whether he could use the excuse of asking for an article to make friends with Lu Xingzhi.
There are four classes in the academy every day, two in the morning and two in the afternoon. They thought they would have lunch at noon, but not only did they have nothing to eat, but they also had to go to the playground to run around to exercise.
Although all the scholars gathered together to run the circle, the scholars in rooms A, B, and C were still divided into three teams, each running in its own way.
There are more than 30 scholars in Lin Yun's group, and the number of scholars in the Class A room is the least, with less than 20 people.The rest are the scholars of Class B, they have the largest number of people, and they entered the academy earlier, and they are not under the pressure of the upcoming scientific examination, so they are the most active on the playground. Hissing and laughing at their slowness like tortoise crawling.
Qin Xiaoting was furious when he heard the words, and told them to send someone out to compete with him alone, but no one answered him.
Ding Yuannan's physical strength is relatively weak, and he suffered a lot when running, and gradually fell to the end of the team. In order to accommodate him, Lin Yun also slowed down to jog with him, so he was ridiculed a lot.
Lin Yun didn't care about this. He was secretly curious, "Why does this Yichen Academy look a bit like a military academy in his previous life? Could it be that Lu Xingzhi wants to train a group of low-level officers for the emperor to replace the power of the four princes and eight princes in the army?" ?”
...
After running the lap.Scholars have a half-hour lunch break, which can be freely arranged by everyone.It's just that most people are too busy doing homework assigned by the lecturer to wander around.
For Lin Yun, an essay on classics and a few arithmetic problems is not difficult at all. His current essays on classics and meanings can already be drafted first, and then written in one stroke.
Lin Yun wrote fast, and Ding Yuannan was not slow in writing, and the two of them finished their homework almost at the same time.
Qin Xiaoting frowned tightly, competing with several arithmetic problems.Lin Yun wanted to give him some advice, but was stopped by Ding Yuannan, who told him that if he was found out helping with homework, both of them would be expelled from the academy.
Unable to bear to see Qin Xiaoting suffer, Lin Yun and Ding Yuannan walked out of the room together to get some air.
The sky outside was a bit gloomy. Ding Yuannan rubbed his palms and smiled at Lin Yun: "Looking at the weather, it's likely to snow tonight."
Lin Yun hurriedly asked, "How long is Xiumu?"
Ding Yuannan smiled and said: "There are still five days, why? You just came here today, and you want to go home?"
Lin Yun chuckled and said, "I've just made an appointment for a marriage. I hope that Xiu Mu can see his wife who hasn't married when he goes back."
Ding Yuannan said happily: "How old are you, so you want to get married?"
"Don't worry about getting married, make a marriage first, it's safer."
"Understood, the siblings must be stunning beauties, right?"
"Okay."
Lin Yun said a word modestly, then smiled and asked, "Do you have a girlfriend?"
Ding Yuannan smiled and said: "I have been married for many years, and my children are already three years old."
"what!"
Lin Yun exclaimed, and immediately cupped his hands in congratulations: "Congratulations! Congratulations!"
Ding Yuannan: "If there is a chance in the future, I will invite you to my house as a guest."
"Then I'll wait."
Lin Yun continued to ask: "Brother Yuan Nan, after the scholars of this academy leave their official positions, have any of them served in the army?"
Ding Yuannan nodded and said: "Yes, those scholars who failed the imperial examination, if they don't want to take the exam again, they can go to work in the Beijing camp. Most of them are low-level military officers and grain officials."
Lin Yun said with a smile: "No wonder the academy is so strict about arithmetic. It turns out that it is to give scholars a way out."
Ding Yuannan: "If I fail the imperial examination next year, I also want to serve in the army."

Lin Yun said in surprise: "Your grades are so good, why don't you try a few more times?"
Ding Yuannan laughed and said: "The imperial examination is for becoming an official. Since you can become an official if you join the army, why do you have to take the imperial examination?"
"But~"
Lin Yun was out of words now. Ding Yuannan was right. Since he could give up his pen and join the army, it would be a good choice to start with low-level officers like food and grass officers.
