The next day, Li Jin went to the academy refreshed.
He had previously told Wan Jiaoyu that he also had a share of the 40% of the net profit, so, of the three hundred taels, at least 62 taels had to be allocated to Wan Jiaoyu.
But giving money directly in person is not in line with the habit of scholars. Li Jin negotiated a date with Wan Jiaoyu and planned to visit him another day.
As a result, in fact, only two hundred and forty-two were in hand. Li Jin didn't have the habit of sitting on the mountain, and he planned to take out two hundred taels to do business.
Whether it's buying some land, hiring people to farm it, or buying some remote but quiet space to build a house in the inner city, it's a good plan.
However, if Li Jin really intends to do business directly, then he has to personally visit to understand the market.
Everything has to be done step by step, and I can't eat a big fat man in one bite.
After the compilation of "Nongsang Suanjing" was completed, the prefect also assigned more tasks to Li Jin.
But after this battle, Li Jin himself had a lot of interest in 'adapting scriptures'.
When he was taking the county exam before, he thought about compiling an introductory math book independently.
After all, "Nine Chapters of Arithmetic" is still too esoteric for those young Mengtong.
When Li Jin came to visit Wan Jiaoyu, he shared his thoughts. After all, if he really planned to do this, he might have to trouble Wan Jiaoyu for proofreading in the future.
Wan Yun's expression at home is quite gentle, unlike in the academy, where he has always been stern.
Perhaps Li Jin and him were similar in life experience and age, and he also felt a lot of sympathy for Li Jin.
Hearing Li Jin say that "Nine Chapters of Arithmetic" is esoteric, Wan Yun said with a smile, "Are you the county exam and the prefectural exam that Xin Chounian participated in?"
Li Jin said: "Exactly."
"Then you still remember that the prefect presided over the compilation of a book "Arithmetic: Detailed Explanation", which was completed by the other three teachings of the Department of Arithmetic."
When Li Jin heard it, he was immediately impressed. At that time, he read few books, and only had two books on the classics in his hand.
Before the county examination, he was also immersed in his studies, and then compared with this "Detailed Explanation", he thoroughly understood the "Nine Chapters of Arithmetic".
Li Jin smiled and told the scene of his study at that time, "It's really thanks to this book."
Wan Jiaoyu said again: "But I heard what you meant, not to continue to annotate the scriptures, but to independently compile the enlightenment books of arithmetic?"
Li Jin replied: "The student has this plan." Then he took out a booklet with no six pages sewn and presented it to Wan Jiaoyu, "This is the outline listed by the students, and I also asked the teacher for guidance."
The first thing Li Jin listed was the multiplication table. This has long been called "Nine-Nine Multiplication Songs", but it is arranged from high to low. eighty-one'.
Li Jin intends to reverse it, starting with 'one-for-one', but he doesn't know whether this method is feasible or not.
After all, this is about Meng Tong's mathematical enlightenment.
After Wan Jiaoyu read it, he looked indifferent at first. After all, he had seen many colleagues who had the same idea as Li Jin, but the books he compiled were all the same and had little value.
Suddenly, his brows furrowed, his face thoughtful.
Li Jin has been sitting on the spot drinking tea, quietly waiting for Wan Jiao to reply to himself.
Wan Jiaoyu read the thin booklet for an hour.
After reading it, there was nothing but admiration and admiration in his eyes, and he said, "It's whimsical! But it's incomparably wonderful!"
Li Jin breathed a sigh of relief. He thought that such a bold idea would be directly criticized by Wan Jiaoyu.
But Wan Yun changed his words, "Li Jin, Li Jin, your idea is too bold. I will recommend the mountain chief for you tomorrow. I can't control this matter."
Li Jin's heart hung in his throat again, and he felt that he was still in a hurry.
It would be nice if he introduced this as enlightenment when he was somewhat famous.
But he doesn't regret his decision. It is important to be safe. His body has not yet reached the weak crown, and he must have the momentum of a young man when he is young.
If you have any ideas, you have to come up with them boldly, otherwise you will keep thinking about it, and you will be afraid of your feet. When you are old, you will find that there is no 'young and frivolous thing' worth remembering when you are young.
The mountain chief looked at Li Jin's outline, pondered for a while, and only gave him one sentence: "Just do it."
Li Jin is currently in the hospital, and if the mountain chief thinks this idea is not good, he will not let Li Jin let it go.
But even the mountain chief did not give Li Jin any guarantee on the spot.
But his words are enough.
A hundred years later, someone saw the origin of the "Mengxue Suanjing" in the memoirs of Wan Yun, the minister of the Ministry of Industry. When translated into vernacular, it is "The chief of the mountain told him that you can do it, and he will independently compile a book according to his own ideas." This concise and easy-to-understand scripture of Mongolian learning and arithmetic. At that time, he was just a young boy who had just left the village, and he was not a weak crown. '
Compiling books and visiting fields in the fields had to be done by himself. Li Jin was incapable of doing things alone, so he temporarily put aside the idea of buying land in Fucheng.
Put the money at home and save it for a few months. After the college entrance examination, you will be able to get the fame and fame, and you will get rent-free when you buy the land.
Before Li Jin went to Ningxing Academy, the first place in the end-of-month assessment was 'Fengshui takes turns, this month's turn for me'.
But after Li Jin arrived, in the first month everyone looked at the first Li Jin, and felt that the name was quite unfamiliar. Someone in the crowd asked who this person was, but only a few people answered, 'He is the leader of this year's government test, follow me Examination in the same year'.
In the second month, when Li Jin's name took the first place, everyone said, 'This person is very lucky.
In the third month, everyone was silent, and then they all cheered up to see who the second place was.
Since Li Jin became famous in the academy, there are many people who want to make friends with him, and some even have a reputation in Fucheng.
Li Jin also participated in some literary conferences at a suitable time, but most of the time he was in the Department of Mathematics, so he did not accept many invitations.
As Li Jin became more and more famous in the circle of scholars in Fucheng, the examiners of the previous academy exams also noticed him.
But the examiner wasn't so bad at heart, and the prefect's relegation of the student from the 'Class A' was a warning to him.
He himself is a Confucian official who teaches Confucianism, and it is disgraceful to do something in the government examination.
The prefect didn't publicly deal with him because he gave him face, and he knew how to accept it when he saw it.
On the other hand, the student who was ranked second was very resentful about this, because he could only be placed in class B because he scored a 'second class' in the government exam.
However, he also has real talents and practical learning, and he can enter the first class by ranking in the first class three times in a row.
In the fourth month, this man named Lu Changdong finally entered Class A as he wished.
Next, he thought that he would be able to teach him how to compete with Li Jin. The rankings in the government exam are already powerless, but he has to prove that he is the most powerful one.
Even though Li Jin usually speaks less, but in the debates in the lecture hall, he cites scriptures and the data is clearly listed, and few people can debate with him to the end.
By December, Lu Changdong had already forgotten what his original intention was. Instead, whenever he could debate with Li Jin to the end, he would laugh like a two-hundred-pound fat man after school.
Lu Changdong thought, that incident was always his and his teacher's fault, and Li Jin was completely innocent.
Besides, Li Jin also used his strength to convince Lu Changdong of losing.
Just after Lu Changdong thought that this was Li Jin's full strength, "Nongsang Suanjing Simplified Version" suddenly caused a sensation in the entire academy.
This book was originally based on the request of the prefect, and the head of each village should buy at least one set and return it to the villagers to reasonably arrange farming time and farming methods.
But there are quite a few math questions, which are closely related to the imperial examinations.
There was a student in the academy whose father was the head of their village. He went home during his break and saw that his father was studying "Nongsang Suanjing Simplified Edition".
The student laughed directly at the time: "Father, it's difficult for me to calculate the scriptures, how long do you have to study it?"
Before he could finish speaking, he was beaten by his father with the sole of his shoe.
His father asked angrily, "Difficult? This is a question that I can understand, you tell me it's difficult? You still take the exam for a scholar? Just come back and enlighten the young children in the village!"
The student felt that his father was joking, took a look at the book, and was stunned.
"Dad, stop beating, this is different from my scriptures!"
In the end, he took out his scripture book, and his father, the village chief, looked at the tongue-in-cheek explanations and found out that the child really didn't lie.
But can I still apologize to my son
The village chief said: "You people who are taking the exams for Xiucai should study a little harder, and return my book to me."
"Father, where did this book come from? Can you buy it? If you can't buy it, let me copy, copy... Li Jin?!"
Later, after the introduction of this student, most of the students in Class B bought a set and came back to study.
The math problems in the last month-end assessment before the Chinese New Year happened to be the changes in rainwater, drainage irrigation, drainage time and drainage volume.
The algorithm is not difficult, but it is difficult to understand and figure out the idea, and many students in Class A have fallen into it.
If it weren't for the academy's regulation that they had to be ranked three times in a row before they could change classes, or else Class A would have to lay off more than half of the staff.
After Lu Changdong got the news, he lost his temper.
The thought of wanting to make friends with Li Jin has never been so strong.
But at that time it was the twelfth lunar month, and the Chinese New Year was coming soon. During the period, there would be a ten-day holiday. Lu Changdong didn't see Li Jinren in the academy, so he could only give up angrily.
During that time, Li Jin was stuck in the final chapter of compiling the "Mengxue Suanjing", and he frequently visited Wanjiao to discuss the diversity of solutions.
Wan Yun praised it directly after reading it, "Each question has at least three ideas listed, Li Jin, your book is absolutely amazing!"
Li Jin said modestly: "The teaching is wrong."
Wan Jiaoyu didn't have many people in his family, and he didn't marry a wife. He was a little lonely during the New Year, but he didn't care about it, he just said: "Li Jin, after you finish writing, I'll take advantage of this time to proofread it for you, and then present it to Shan Chang for review."
"Thank you for the instruction."
When Li Jin delivered the final draft to Wan Yun, he also brought a lot of New Year's goods, including Qin Muwen's glutinous rice chicken and steamed pork ribs.
Wan Jiaoyu simply let him eat, and when he ate the ribs, he said, "This skill is really excellent, you are really lucky."
Hearing him mention Qin Muwen, Li Jin's brows softened due to the wind and snow, and the corners of his lips unconsciously brought a smile.
"It is indeed my blessing. If you are free, my wife and I will greet you by sweeping the couch."
Wan Jiaoyu, who has never accepted any invitation, agreed: "Okay, I will definitely go."
