Chapter 89: 89th

The next day, Li Jin went to the academy refreshed.
He had previously told Wan Jiaoyu that he also had his share of the 40% of the net profit margin. Therefore, out of these three hundred taels, at least sixty taels had to be allocated to Wan Jiaoyu.
However, it is not in line with the habit of scholars to directly give money in person. Li Jin discussed the date with Wan Jiaoyu and planned to visit him another day.
In this way, only two hundred and forty taels are actually available. Li Jin does not have the habit of sitting and eating in the air, he plans to spend two hundred taels to do business.
Whether it is buying some fields, hiring people to cultivate, or buying some remote but better houses in quiet open spaces in the inner city, it is 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, the big fat man can't eat a bite.
After the compilation of "Nong Sang Suan Jing" was completed, the prefect also assigned more tasks to Li Jin.
However, after this battle, Li Jin himself became interested in the'adapted calculation script.'
Before taking the county exam, he thought about compiling an introductory math book independently.
After all, "Nine Chapters Arithmetic" is still too profound for those young Mengtong.
When Li Jin visited Wan Jiaoyu, he explained his thoughts. After all, if he really intends to do this, he might have to trouble Wan Jiaoyu for proofreading in the future.
Wan Yun's complexion at home is quite mild, unlike in the academy, who has always been stern.
Perhaps Li Jin is similar to his life experience, and his age is not too different. He also feels a lot of sympathy for Li Jin.
Hearing Li Jin said that "Nine Chapters of Arithmetic" was profound, Wan Yun smiled and said: "Are you the county and government test that Xin Chounian participated in?"
Li Jin said: "Exactly."
"Then you can still remember that the prefect presided over the compilation of a book of "Arithmetic·Detailed Explanations", which was completed by the other three teachings of our mathematics department."
After Li Jin heard this, he was immediately impressed. At that time, he read few books and only had two mathematics books in his hand.
Before the county test, I was immersed in study, and then compared this "Detailed Explanation", I thoroughly understood the "Nine Chapters of Arithmetic".
Li Jin smiled and told the scene of his study at the time, "Thanks to this book."
Wan Jiaoyu said again: "But I heard what you meant, not to continue to annotate mathematics, but to independently compile enlightenment books on mathematics?"
Li Jin replied: "Students have this plan." Then he took out a thin booklet with no six pages stitched and presented it to Teacher Wan. "This is the outline listed by the student. Please also ask for advice."
The first one Li Jin listed was the multiplication table. This has already been the "Nine-Nine Multiplication Gesture", but it is arranged from high to low. In other words, Meng Tong recites these formulas, and the first sentence is "Nine-Nine eighty-one'.
Li Jin intends to reverse it and start with "one by one", but he doesn't know whether this method is feasible or not.
After all, this is about Mengtong's mathematical enlightenment.
After reading Wan Jiaoyu, his expression was calm at first. After all, he had also met many colleagues who had Li Jin's ideas, but the books he compiled were all the same and had no value.
Suddenly, his brows wrinkled, his face thinking.
Li Jin has been sitting in place drinking tea, quietly waiting for Wan Jiaoyu to reply.
Wan Jiaoyu read a thin booklet for an hour.
After reading it, there was nothing but admiration and appreciation in his eyes, and he said, "Whimsical! But it's amazing!"
Li Jin breathed a sigh of relief. He thought that his bold idea would be directly criticized by Wan Jiaoyu.
But Wan Yun changed his words, "Li Jin ah Li Jin, your idea is too bold. Tomorrow I will introduce Shan Chang for you. I can't do this."
Li Jin's heart hung in his throat again, and he felt that he was too hasty.
It would be nice if he was a little prestigious.
But he doesn't regret his decision. It is important to be safe. His body is not yet weak, so he must have the enthusiasm of young people when he is young.
If you have any ideas, you have to boldly put it forward, or else you will always think about the past and the future, and you will find that when you are old, you will find that there is no ‘young frivolous thing’ that can be missed.
The mountain leader looked at Li Jin's outline, pondered for a long time, and only gave him one sentence: "Just do it."
Li Jin is now in the hospital. If Shan Chang thinks this idea is not good, he will not let Li Jin do it.
But even Shan Chang did not give Li Jin any guarantee on the spot.
But his sentence is enough.
A hundred years later, someone saw the origin of "Meng Xue Suan Jing" in the memoirs of Wan Yun's late life from the Shang Shu of the Ministry of Industry, and translated it into the vernacular: "Shan Chang said to him that you can do it, and he will independently compile one according to his own ideas. This concise and easy-to-understand mathematics. At that time, he was just a child who had just left the village, and he was not as weak as the crown. ’

Compiling books and visiting the fields and fields had to be done by himself. Li Jin was alone and lacking skills, 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 you finish the college exam, you will have a reputation and you will be rent-free if you buy the land.
Before Li Jin went to Ningxing Academy, the first place in the assessment at the end of each month was "Feng Shui turns around, and this month turns to me."
But after Li Jin came, everyone looked at the first Li Jin in the first month, and felt that the name was quite strange. Someone in the crowd asked who this person was, but only a few people answered, "This year’s government trial is the first one, follow me Tested in the same year'.
auzw.com In the second month, seeing Li Jin’s name occupy the first place, everyone said, ‘This man is so lucky, and he is so powerful in the policy argument. He must have just memorized this paragraph before the exam’.
In the third month, everyone was silent, and then they all cheered up to see who was the second.
Since Li Jin became famous in the academy, there are many people who want to make friends with him, and some even have a face in Fucheng.
Li Jin also took the right time to participate in some literary meetings, but most of the time he was in the Department of Mathematical Studies, so he did not accept many invitations.
As Li Jin became more and more famous among scholars in Fucheng, the examiner of the previous hospital examination also noticed him.
But the examiner's mind was not so bad. The prefect degraded the student as "Class A", which was a warning to him.
He himself was a Confucian-teaching Confucian official, and it was disgraceful to use his hands and feet in the official examination.
The prefect gave him face and didn't deal with him publicly, and he knew how to accept it.
However, the student in the second class was very upset about this, because his test result was'second class' and he could only be placed in the second class.
However, he also has real talents, and he can enter Class A if he ranks in Class A three times in a row.
In the fourth month, this fellow named Lu Changdongdi finally got his wish and entered Class A.
Next, he thought he could compete with Li Jinyi. The official test ranking has been unable to recover, but he has to prove that he is the most powerful one.
Regardless of Li Jin's usual low talk, but in the lecture, he quoted the classics and the data was clearly listed. Few people could argue with him to the end.
By December, Lu Changdong had forgotten what his original intention was. Instead, whenever he could argue with Li Jin to the end, he would laugh like a two-hundred-jin fat man after school.
Lu Changdong thought, that incident was always the fault of himself and the teacher, and Li Jin was completely innocent.
Besides, Li Jin also used his strength to convince Lu Changdong to lose.
Just after Lu Changdong thought that this was Li Jin's full strength, "Nong Sang Suan Jing · Simplified Edition" suddenly caused a sensation in the entire academy.
Originally, this book was based on the requirements of the prefect. The head of each village bought at least one set to return to the village to arrange farming time and methods for the villagers.
However, there are many arithmetic questions which are closely related to the imperial examination.
There was a student in the college whose father was the head of their village. He took advantage of the rest time to return home and saw his father studying "Nongsang Mathematical Scripture · Simplified Edition".
The student smiled directly at the time: "Father, this calculation is very difficult for me. When will you have to study."
Before he could say anything, he was beaten by his father in the bottom of his shoe.
His father asked angrily: "Difficult? This is a question that I can understand. You tell me that it is difficult? Are you still taking a Xiucai exam like this? Just come back and enlighten the children in the village!"
The student thought his father was joking, took the book and looked at it and was shocked.
"Father, stop beating, it's not the same as my arithmetic book!"
In the end, he took out his arithmetic book, and his village chief father looked at the slurred explanations, only to realize that the child did not lie.
But can I still apologize to my son?
The village chief said: "You people who test for talents should learn a little harder and return my book to me."
"Father, where did this book come from? Can I buy it? If I can't buy it, let me copy or 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 arithmetic questions in the last month-end assessment before the new year also 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 ideas, and many students in Class A have fallen in.
If it weren’t for the academy’s rule that three consecutive top rankings were required to change classes, otherwise Class A would have to lay off more than half of its staff.
After Lu Changdong got the news, he lost his temper.
The thought of friendship with Li Jin has never been so strong.
But it was already in the twelfth lunar month, and the Chinese New Year was about to take place, during which there would be a ten-year holiday. Lu Changdong did not see Li Jin in the academy, so he could only give up.
At that time, Li Jin happened to be stuck in the last chapter of the compilation of "Meng Xue Shu Jing". He frequently visited Wan Jiao Yu to discuss the diversity of solutions.
After reading it, Wan Yun praised him, "Each question lists at least three ideas, Li Jin, your book is absolutely amazing!"
Li Jin said modestly: "The instruction is absurd."
There are not many people in Wan Jiaoyu's family, and he has no wives. The Chinese New Year is a bit deserted, but he doesn't care about these things. He just said: "Li Jin, I will proofread it for you during this time after you finish writing, and then present it to the mountain leader for review."
"Thanks for the instruction."
When Li Jin sent the final draft to Wan Yun, he also brought a lot of goods, including Qin Muwen's glutinous rice chicken and steamed pork ribs.
Wan Jiaoyu simply kept him for dinner, and when he had the ribs, he said: "This craftsmanship is really amazing, you guys are so lucky."
Hearing his mention of Qin Muwen, Li Jin's eyebrows were softened by the wind and snow, and the corners of his lips smiled unconsciously.
"It is indeed my blessing. If you are free, my wife and I will welcome each other."
Wan Jiaoyu, who has never accepted any invitations, agreed in one mouth: "Okay, I will definitely go."
