Chapter 143 "Nine Chapters on Arithmetic"

Ma Feifei is really not a tiger. Since the system has such a high price, it must mean that the private room is worth that price.

And based on the Enlightenment series of products in the private room, Ma Feifei felt that the key to the increase in the cost of the private room was this.

Maybe a person with a dull aptitude can realize supernatural powers even if he ran into a private room to read a book.

After collecting the spirit crystals of the two, Ma Feifei led the two to the front bookshelf.

More than half of the books on the bookshelves were missing, but there were still quite a few left, with hundreds of them left.

Seeing so many blue quality books on the bookshelf, Gongsun Qiong couldn't help sighing: "I still remember the first time I came to the bookstore to read books, there were very few books in the bookstore, it seemed that there were only three books at that time? Zhou Zhuling and his brother came late, so they could only read one book together."

Zhao Xiaodao also nodded, and said: "Yes, I still remember a book called 'Poems', thirty poems, which was written by the owner himself, and he wanted to trick me into reading it after he finished writing it."

When it comes to the past, although it is only a few months, it seems like a world away. Even Ma Feifei can't help but sigh: "Yes, it has been so long in the blink of an eye."

In the blink of an eye, Ma Feifei has been living here for half a year.

"But then again, shopkeeper, where did you get these books? Why do they have such miraculous effects?" Zhao Xiaodao asked curiously.

"Xiaodao." Gongsun Qiong called Zhao Xiaodao.

Zhao Xiaodao seemed to come to his senses, stuck out his tongue embarrassedly, and said, "Sorry, I shouldn't have asked."

Ma Feifei shook his head with a smile and said, "It's okay."

But he didn't explain anything. Everyone has an unforgettable memory in their hearts, and there are also many secrets that they don't want to share with others.

"What kind of books are you looking for?" Ma Feifei asked, waving away those wild thoughts.

"I want to improve my cultivation. The realm is too weak to protect the president." Zhao Xiaodao said.

Gongsun Qiong said with a smile: "It would be great if there was a book similar to "Half Acre of Flower Fields", and "Huan Zhu Ge Ge" would also be fine."

She can't practice, and those books that can increase her cultivation and martial arts are meaningless to her.

Ma Feifei nodded and began to search on the bookshelf.

The first book that Ma Feifei got was the work of a famous master.

Gu Long: "The Sword of the Three Young Masters".

At the same time, the basic introduction of this book appeared in Ma Feifei's mind.

"The Sword of the Three Young Masters"

Quality: blue

Store purchase price: 50
Obtainable benefits: Gongfa martial arts
This is the difference before and after the system upgrade. Now as long as Ma Feifei gets any book, the relevant information of this book will appear, and he no longer has to guess what is in each book and what kind of benefits it can bring to everyone.

But this wasn't for improving cultivation, so Ma Feifei put it back and continued to search.

"The White-haired Witch"

Quality: blue

Store purchase price: 50
Obtainable benefits: Gongfa martial arts
Neither is this one.

"Seven Swords Down the Tianshan Mountains"

Quality: blue

Store purchase price: 50
Obtainable benefits: Gongfa martial arts
Nor is it.

"Legend of Pingyao" (Tianshu Qitan)

Quality: blue

Mall purchase price: 50 million
Benefits available: repair
Okay, that's all.

Ma Feifei handed the "Legend of Pingyao" to Zhao Xiaodao, and said, "This is it. If you can comprehend it, it should be able to increase your cultivation."

Zhao Xiaodao accepted "Legend of Pingyao" with a satisfied face.

Then Ma Feifei started to help Gongsun Qiong choose books again, but compared to Zhao Xiaodao, Gongsun Qiong reads books to see the artistic conception, not to get benefits, so it is much simpler; in fact, Gongsun Qiong can also read those books with Profitable books, after all, the stories in those books are also very exciting.

But who told her to be a girl? She only liked romantic novels, and she wasn't interested in those about fighting and killing.

"Huh?" Suddenly, when Ma Feifei was looking for books on the bookshelf, he found a rather strange book, and Ma Feifei couldn't resist taking it from the bookshelf.

"Nine Chapters on Arithmetic"

Quality: blue

Mall purchase price: 50 million
Gainable Benefits: Nine Chapters Using Mathematics
"Fuck!" Ma Feifei looked at "Nine Chapters of Arithmetic" with a dazed look on his face. Can there be such a book?

"What's the matter, shopkeeper?" Gongsun Qiong looked at Ma Feifei suspiciously.

'Cough cough' Ma Feifei coughed, looked at Gongsun Qiong, and asked, "Sister Gongsun is a businessman, right?"

Gongsun Qiong nodded and said, "Yes."

"Do you have some research on arithmetic?" Ma Feifei asked again.

"Of course, the president is very good at mental arithmetic. No one in the chamber of commerce is her opponent." Zhao Xiaodao at the side said proudly, as if what he said had something to do with her.

"I think you can try to read this book." Ma Feifei handed "Nine Chapters of Arithmetic" to Gongsun Qiong.

Gongsun Qiong took the book, looked at the title on it, and couldn't help but read out: "Nine Chapters of Arithmetic?"

Ma Feifei looked at the book in Gongsun Qiong's hand and said: "This contains a set of extremely advanced arithmetic methods. If you can comprehend it, it should be of some help to you in arithmetic."

Speaking of "Nine Chapters of Arithmetic", it is the first mathematics monograph in ancient China and the most important one among the "Ten Books of Suanjing", which was written around the first century AD.The book is very rich in content, and systematically summarizes the mathematical achievements of the Warring States, Qin, and Han Dynasties.At the same time, "Nine Chapters on Arithmetic" also has its own unique achievements in mathematics. It not only mentioned the problem of fractions for the first time, but also recorded problems such as surplus and deficiency. The chapter "Equations" also expounded negative numbers and their addition and subtraction for the first time in the history of mathematics in the world. algorithm.It was the most concise and effective applied mathematics in the world at that time, and its appearance also marked the formation of a complete system of ancient Chinese mathematics.

"There is such a wonderful book?" Gongsun Qiong was a little surprised.

Ma Feifei touched his nose in embarrassment. It was the first time he found out that there are books with such income in the bookstore. It seems that he still doesn't know enough about the bookstore!
"Then I'll just read this one." Gongsun Qiong was obviously still very interested in books about arithmetic, and took Zhao Xiaodao to the private room, ready to read the "Nine Chapters on Arithmetic".

"Go back and browse all the books on the bookshelf to see if there are other books with different benefits." Looking at the two people who entered the private room with books, Ma Feifei went back to the cashier and thought silently.

"But before that, let's copy the reward book first." Shaking his head, Ma Feifei picked up the pen and sighed.

There are more and more books in my mind, and I haven’t had time to copy the remaining few books from last time. Yesterday, the system rewarded another yellow-quality "Sun Tzu's Art of War", which is equivalent to the previous "Pokemon "Copied in vain, everything is back to the original point.

But when it comes to the rewarded "Sun Tzu's Art of War", I have to mention the new side mission - transcendence and sanctification.
