Chapter 63: 63

Li Jin resisted his shock, and first read an orthodox historical record.
Now he is used to reading from right to left and upright.
From this look, Li Jin found that in fact, this world overlapped a lot with the ancient times of his previous life, but there were more brothers in terms of gender.
Moreover, although the names of each emperor are different, the major historical events that have occurred are likely to be similar.
Li Jin breathed a sigh of relief. While listening to the people around him discussing how important arithmetic is, he picked up a book on geography and read it.
It turns out that the capital of this era is also Yanjing. Hongyan Village is in the north of the country. If you calculate it according to the map of the previous life, it is probably in the area of ​​Shanxi and Gansu.
Li Jin is actually quite satisfied with the landforms here. After all, the ancient traffic was underdeveloped. Most places were dirt roads, potholes, and muddy when it rained.
If he was in Shu, it would take at least three months to go to Yanjing.
Most of the Shaanxi-Gansu generation are plains, and they are connected to the Wei River, so the transportation is relatively convenient.
After Li Jin understood what he wanted to know, he went to look at Nine Chapters Arithmetic again, and only went outside when he felt hungry.
The owner of the bookstore saw so many foreign students like this, read a day but didn't buy a copy, he didn't get annoyed, he smiled and watched the students go away.
Anyway, they will still come to buy arithmetic books in two days.
At this moment, if anyone is stingy with money and refuses to buy, then wait for the famous fall.
As long as you are discerning, you will definitely come to buy it after considering it.
When Li Jin returned to the inn, Chen Xiran had already renewed the lease for the three of them. The day-day renewal only requires ninety wen, which can save a little.
After seeing Li Jin, Chen Xiran hurriedly ordered food and said, "I'm going to be fainted from hunger, A Jin, can you gain something from this trip?"
Li Jin looked at him and said two words calmly: "Arithmetic."
Chen Xiran was about to jump up from the stool in the next second, and he lowered his voice: "Is it really possible to take arithmetic exams? I thought the people in the teahouse framed me!"
Li Jin said: "Nearly half of the books on imperial examinations in the bookstore are arithmetic, and it should be fine."
He paused and continued: "Before the curfew, let's go to buy books. About 90 candidates came to register today. The registration time is five days, and at least 500 people take the county exam.
There are not complete arithmetic books in our town, and I am worried that those in the county will be sold out soon. "
Chen Xiran could only follow Li Jin to speed up his meal, and then go shopping.
At this time, don't block the luck that 10% can't test arithmetic.
The shopkeeper of the bookstore saw this young and handsome boy coming back again and said, "You two want to buy books?"
Li Jin said: "Yes, I would like to ask the shopkeeper, which arithmetic books cover a wide range and are suitable for beginners?"
The shopkeeper said: "Since you asked so, then I won't blame you."
He turned and went to the bookshelf to take three books, "These three are countless introductory books, and this one is recommended by our prefect. Now there is not much time before the county examination, and it is not easy to acquire one.
Let me tell you quietly that all the books I have here were prepared by the master of Yamen the day before yesterday. "
The day before yesterday...that is, two days ago.
Li Jin thought, it means that the students in the county have only recently learned that they have to take the math test, so everyone is at the same starting point.
Hearing this, Li Jin stopped hesitating and chose one book with the widest coverage, and the other was compiled by the prefect. A total of three hundred essays cost him 600 essays.
In any case, the prefect must be given the face, and the county magistrate may also study the books of the prefect before asking the question.
Otherwise the book would not be here.
Chen Xiran had no such worries and bought all three books at once.
Li Jin said, "You can't finish it again."
Chen Xiran: "I'll buy a peace of mind!"
Chen Xiran also wanted to buy the last one for Li Jin, but Li Jin waved his hand and refused, "The content is the same with little difference."
Introductory books are just, really don’t need too many.
Moreover, as a medical student, he has studied advanced mathematics, linear algebra, medical statistics, etc. for so many years, and he still has a solid foundation.
Moreover, this kind of introductory arithmetic exercises, in fact, Mr. Song has also discussed before. After all, mathematics is also part of the imperial examination.
It's a pity that Mr. Song said before: "I haven't taken the math test for so many years, and you probably won't take the test this time. You only need to understand these."
Previously, Mr. Song said that the most difficult problem is probably the chicken and the rabbit in the same cage, but the description of the topic is rather obscure, and you need to read it several times to avoid misunderstanding the meaning.
However, Li Jin felt that if he really took arithmetic in the county test, he might have something to do with industry.
In this book, the prefect is listed some basic arithmetic to solve the purchasing problems in life. Of course, if it involves the Ministry of Industry and the Ministry of Households, it is even more esoteric.
This is no longer pure mathematics. The word'applied' should be added in front to become'applied mathematics'.
On the second day, Li Jin and Chen Xiran went to the bookstore together, and sure enough, everyone was looting books.
But the book compiled by the prefect recommended by the treasurer yesterday is out of stock.
Huang Yiling sweated profusely in the winter: "We just came to register one day late, why this book is gone!"
Zhou Qi was already bitter: "Without that book, we couldn't pass the exam this time."
Huang Yiling said: "No, no, let's go to the shopkeepers of various bookstores separately, or else we will buy the arithmetic manuscript at a high price of a few silvers."

Xu Zifan said: "Silver is not a problem. I am afraid that other examinees will use us as competitors and will not let us copy any amount of money."
"This kind of arrangement is simply unreasonable. I have come to register for five days. This is just the second day for us. Why can't we even buy books!"
Huang Yiling squatted helplessly on the side of the road, "The people who signed up a few days later don't even know if they want to take arithmetic exams!"
Hearing what he said, both Zhou Qi and Xu Zifan's eyes showed despair.
Although they know that they need to take a test of mathematics, the book compiled by the prefect is the most important thing! If you can't buy a book, it's better not to know.
Chen Xiran watched as a group of students came running, and after asking questions, he hurried away, suddenly frightened.
If Li Jin hadn't brought him to buy books yesterday, then the state of these people today is probably a true portrayal of them.
Chen Xiran said: "A Jin is still thoughtful."
Li Jin sighed and said, "I'm not here to watch the excitement today. Some of the bookshelves of these "Four Books" and "Five Classics" have also been recommended by county officials or prefects. There are too many books, and you can't buy them.
Take advantage of today to write down the important knowledge points, and go back and write carefully. "
It's not that Li Jin didn't know the prophet, but after he bought the mathematics book from the prefect last night, he found a small seal on the back of the book.
He looked at the candle carefully and found the seal of the prefect.
But yesterday Li Jin saw a lot of books with this seal here, so he had this plan.
The notes of each book have been explained in detail by Mr. Song. Now, looking at these books with seals, it is tantamount to ‘guiding the title’.
Therefore, Li Jin does not recommend Chen Xiran to buy the book directly.
All you need to do is to review the knowledge points you have received, and don’t make mistakes like ‘Sister, I’m Thinking’.
Chen Xiran has a good memory. Hearing this, although he didn't want to read a book, he knew that Li Jin could not remember it alone. So he cooperated with Li Jin.
A short while before the curfew, Li Jincai and Chen Xiran walked out of the inner city.
They are leaving tomorrow. The two of them haven't even visited the four main streets, eight small streets, or even the many shops in the county seat. They spend the whole day in the bookstore.
Chen Xiran was a little melancholy, looking up at Jiaojiao Mingyue, "Exams are really difficult."
After reading the book for a day, Li Jin felt dizzy. He didn't like to say encouraging words, so he walked quietly under the moonlight.
Chen Xiran suddenly changed the subject: "I heard someone sing a song."
Li Jin was silent, thinking about going to the brothel at this time?
Li Jin said: "Tomorrow, I will take another day to go home. Take a good rest today."
In the end, Chen Xiran said, he knows which is lighter and heavier, and there is such a self-disciplined person by his side, he will not die.
Li Jin went back to take a bath, but Chen Xiran was stopped by Li Jin today and failed to go to the brothel, so he planned to go to sleep without taking a bath.
The master who drove the car was also regarded as the old man of the Chen family. Seeing that Chen Xiran grew up, he completely obeyed his young master's will, and he didn't even prepare foot washing water.
After Chen Xiran took off his shoes, he thought for a while, worried that he would be disgusted by taking off his shoes with Li Jin in the car tomorrow, so he went downstairs to take a bath.
Li Jin also went to take a bath. He didn't worry about the exam, he had done his best to control himself, and he was left with his destiny.
Instead, he was thinking about saving more money and buying a bath tub to go back another day.
But the home is not big enough, which is a problem. Li Jin no longer wants to buy a house recently, it is too expensive to afford it.
Earlier, I saved eleven taels of silver. I spent more than three months on the grain, oil, salt, bamboo-leaf paper and burr paper used for writing at home, and occasionally some small snacks.
This time, it will cost a couple of dollars to sign up for the test and buy books.
In the next month's exam, if there are five exams, it will be five days. He has to come at least one day in advance, so he will have to spend at least two or two more.
The price of buying a house is still far short of thirty taels.
In fact, when it comes to making money, Li Jin thinks it would be much better to live in the county seat.
He can copy books to a bookstore. A book sells for 300 texts, and a copy of a book is only 120 texts.
The books at this time were so thin that Li Jin could finish copying in one day.
But there is a very practical problem right now, that is, houses in county towns are more expensive.
Li Jin did not expect that one day he would be worried about buying a house.
Early the next morning, Li Jin practiced calligraphy and dictated after washing, but Chen Xiran hadn't woke up yet.
It seemed that staying in the bookstore for a day had a big blow to him. Li Jin planned to go out for breakfast first, but accidentally met the master driver.
He asked: "Master, when do you leave today?"
"It's okay to be late, the snow is gone, and it's easy to walk on the road, just check out and leave."
Li Jin said: "Then I will go shopping in the inner city and come back before the time."
"all good."
In fact, he didn't have anything special, but he just wanted to buy some gadgets for the boy and the little bun. I don't know if the kid who would have laughed happily when he saw his father talking to him in the past few days had he missed him.
But Li Jin already missed them in his heart.
He thought that when both the left and the right had to wait until the end, it would be good to be able to find the gadgets that appealed to the eye.
Bring gifts back to his two cubs.
