Walking all the way to the "Hongwen Pavilion", a private school in Pingtang City, the middle and outer halls of the school neatly arranged several tables, books, bamboo slips are placed on the table, the dazzling array makes people overwhelmed.

Bai Liyan searched carefully, left Hongwen Hall about a tea time, and rushed to the next private school, but still found nothing. After going to a few houses in a row, Bailiyan didn't see Bailiyan buying books, and then He Kuan couldn't help but wonder:

"What book the son is looking for, the old man can ask Zhang to find it on his behalf."

"Let's go to the Tongshu Garden, maybe there will be."

Bai Liyan ignored He Kuan and continued to go to the Tongwen Garden, which was two hundred steps away. The book Bailiyan is looking for is a dictionary, and a dictionary is also fine.

Recently, it was discovered that Bai Liyan's memory is very lacking, and Chinese cannot match new words, which means that there is a reading disorder, although it does not affect expression, but it is not the same thing to not understand.

In addition, the collection of books in the Proton Mansion is very biased, talking about the three obedience, four virtues, etiquette, righteousness and shame, the rule of the monarchy, the etiquette of the courtiers, and there is not even a decent calendar book.

According to He Kuan, the current calendar has 372 days and nights in a year, which is a few days longer than the earth. Bailiyan even thinks that the time of a week and night is longer than that of the earth. Obviously, if you don't understand the calendar, you can't do it either.

According to the preliminary calculation of the celestial body's azimuth and the sextant, the continent under his feet is in the southern hemisphere, and Pingtangcheng is about 367 degrees south latitude.

When she was thinking in her heart, Bai Liyan walked to the Tongshu Garden.

In stark contrast to other private schools and bookstores, the façade of the same library is less than half of that of other books, and the sound of reading aloud is also scattered, and the black paint on the old door plaque has faded, which is no different from an old wooden board.

"This is the Tongshu Garden?"

"Yes, Shizi, this is Tongshu Yuan."

He Kuan affirmed, Bai Liyan glanced at the word "Yuan", because he didn't know it at all, and after matching his Chinese memory, it was a match.

Walking into the academy, unlike other bookstores, books are placed in the outer hall, and books sold in the same library are placed in the verandah of the courtyard, because there are too many books, so they can only be placed under the verandah.

Seeing that there were guests and soldiers accompanying them, a scribe at the entrance stepped forward:

"Dare to ask the old army, it's not from the Jin Kingdom."

"Old man Qiren, this is the prince of Qi Wang."

He Kuandao, the bookmaker's eyes fell on Bailiyan, and he saw that Bailiyan had already "read a lot of books". Seeing this, the bookmaker said:

"It turned out to be the second son of Qiguo, disrespectful and disrespectful. But I don't know why the prince came, can the old army tell me a thing or two. ”

"The old man doesn't know, he just travels with the son."

"Oh......"

The bookmaker was thoughtful, chatted with He Kuan for a while, and then caught up with Baili Yan to wait.

About half a tea time, Bai Liyan's eyes fell on the book "The Literature of the Nations". This book is about a palm-and-a-half thick, and when I opened it, it was, sure enough, a dictionary.

It is very different from Chinese dictionaries and dictionaries. This dictionary starts with examples, uses quoted articles as text examples, explains how to read, how to write, what it means, what common phrases there are, and explains the meaning of phrases and words by quoting examples and examples. And there is an index directory, which can be searched according to radicals and nearphones.

It is not so much a dictionary as a textbook, and the "Literature of the Nations" is a set, a total of seven volumes, each volume has a palm and a half thickness, according to its opening annotation can be known, the full set of books contains more than 5,000 words, tens of thousands of phrases, a total of four specifications of writing methods.

The situation is roughly the same as before the Qin unified China, each country has its own way of writing Chinese characters, so the strokes written in different countries are not the same, and modern Chinese characters are gradually developed from the Qin characters after the Qin unified China.

At present, there are four main writing methods in the Central Plains, one is the old style of the Liang Dynasty, the second is the Central Plains, the third is the East China Sea script, that is, the Jin and Song scripts, and the third is the West Sea style, with Qi, Chen, Yan, Zhao, and Wei as the main users.

Seeing that Baili Yan was engrossed, the calligrapher approached and said:

"Qi Shizi loves this book?"

"Exactly, this son wants to get this book, and he has walked through many bookstores and private schools in a row, and he dares to ask the bookmaker what the price of this book is."

"I'm very sorry for the world, but all the books on this table are on display and are not for sale."

"Not for sale? Why not sell. ”

Bailiyan was puzzled, since he didn't sell it, what would he do with it. At this time, the bookmaker said:

"This is the rule of the library, if you don't sell it, you don't sell it."

Hearing this, He Kuan was annoyed:

"Old man, I see that you are deliberately deceiving me and misleading people!"

Seeing that He Kuan was angry, the bookmaker hurriedly explained:

"No, no, no, the old army misunderstood. This book is said to be discregent, even if it is from the Jin Kingdom, it is not sold. ”

"The people of the Jin Kingdom don't sell either, what is the reason." He Kuan asked.

"I don't know below, if you really want to ask for a book, you can only ask the master of the Academy."

"Okay, you go and invite the deacon to talk, if you can't say why, the old man will ask you, go quickly!"

He Kuan said sharply, with a non-negotiable look. The bookmaker ran away without a trace, all the way to the backyard.

In the backyard sits a school hall, and there are roller curtains hanging on all sides of the hall, and it can be seen that Mr. Yi is sitting in it, and more than ten children are reading aloud. Not far away from a corridor, two old men and a middle-aged plain-clothed warrior in the corridor pavilion sat cross-legged and drank and had fun.

At this time, the calligrapher hurriedly came, and when he saw the old man in Tsing Yi, he stepped forward and said:

"Simon Academy, some people want to ask for the book "The Literature of the Nations", and they have to take it."

"The Nations?" The old man in Tsing Yi frowned in surprise, thought for a moment and then asked, "What kind of person is it?" ”

"It's Qiguo Proton Baili Yan."

"Childe Yan? Is it his servants who ask for a book? ”

"It's Shizi himself."

Hearing this, Simon Hua wondered.

This Bailiyan is in the deep palace compound all day long, and it is said that this son is cowardly and mediocre, how did he come to the Tongshu Yuan to ask for books. Thinking of this, Ximen Hua said:

"You deal with it first, and the old man will arrive later."

"No!"

The bookmaker hurried away, and at this time, the old man in yellow opposite Ximenhua asked:

"What is it that makes the Simon Court so worried, can you elaborate on one or two."

"Don't hide it from Master Wu, it's the proton of Qiguo [Note 1] who came to ask for a book, and the old man was very embarrassed."

"Kikuni proton? It's the son of the Baili Gui Guo family, who is Baili Yan? ”

"Exactly."

"If you don't give it to him, it's over, why bother yourself."

Wu Xuan didn't think so, but Ximen Hua said with a sad face:

"Alas...... The book he wants is by no means ordinary, it is "The Literature of the Nations", this is a grand work, there is an order from the General Garden of Liang Guo, and it is not allowed to sell it if it is not a famous school in the world, and the princes are only allowed to grant two sets for study. Gongziyan wants to buy this book, and the old man is thinking about how to send him. ”

"Hehaha...... The old man thought it was a big deal, and it was not difficult. As long as the Ximen Executive Court promises the old man one thing, the old man will come forward for you in this matter, and Gongzi Yan will have nothing to say. ”

"Hmph, the old man knows that you, a drunkard, want to rob me again. Okay, as long as Master Wu Shu can return Gongzi Yan, and let the Qi people have nothing to say and leave no handle, the old man will give you a ten-year old wine. ”

"Okay, that's a deal."

When the words fell, Wu Xuan took a sip of rice wine, stood up beside the middle-aged man and said:

"Saiqian, you wait here for a while to eat some wine and meat, take the old man to get rid of that Gongzi Yan, and then eat wine with you."

"Master Wu Shu, please be, I will be waiting for you." Sai Qian owes a debt, and he is very respectful.

"Okay, the old man will go and come back."

Wu Suan turned around and went hand in hand with Ximenhua.

But just now, Uncle Kuo didn't say to King Jin, is this Wu still on the way to Pingtang City, why did he arrive first.

Isn't it, the whereabouts of a high-ranking person like Wu Xuan must be erratic, and in these years, communication is not developed, and there is a delay in news, so there is no accurate trust.

At this time, the calligrapher was dealing with Baili Yan, and after a while, the second elder came out of the backyard, saying that he was the second elder, who was actually only in his early fifties, but his temples were white, and his hair was black and white.

Seeing a man in the verandah, Ximen Hua stepped forward and said to He Kuan:

"This Venerable Driver is Baili Yan, the son of the Qi Kingdom."

Ximenhua faced He Kuan, but it was Bailiyan who replied:

"It is the son of this world, who dares to ask if the honorable master is the executive master of the Tongwen Academy."

"The old man of the word master is ashamed, I heard that the prince wants to ask for "The Literature of the Nations", but there is such a thing."

"There is such a thing, but I don't know why the Executive Yuan put this book on display here, but it does not sell this book, what is the reason."

"This ......" At this time, Ximenhua looked at Bailiyan and couldn't help but be surprised.

If nothing else, Baili Yannian is only nine years old, but she speaks very smoothly, which is very different from other children. Thinking of this, Ximenhua quickly looked up and down, and then said:

"This is the rule of the general garden, and it is not for the old man to decide."

"If this son has to take it."

Bai Liyan was resolute, and at this time, the corner of Ximenhua's mouth showed a grin:

"As long as the prince can solve the master of the garden, the executive court can make an exception to sell books to you, can the prince be willing or not."

The ball was kicked to Bai Liyan, and when he hesitated, He Kuan stepped forward and said:

"Why did the ruling court make things difficult for my family, and I am willing to answer the question for the son."

As soon as the words came out, Wu Suan smiled slightly, took a step forward, and his eyes were full of eyes:

"Just you?"

"Can't!" He Kuan shouted.

Wu Xuan was dismissive:

"If you can answer the old man's question, the old man will not be embarrassed by the prince of the country, if you can't answer, please leave quickly, don't embarrass the garden to make an exception."

"Okay, please ask the master to ask the question."

He Kuan was not afraid of danger, and Bailiyan didn't stop him, but wanted to see what the hell these two old guys were doing.

At this time, Wu Xuan was confident, and the arrogance in his eyes killed everything in seconds:

"The question is as follows, there are several chickens and rabbits in the cage, a total of eighty-eight, chickens and rabbits have two hundred and forty-four feet, and ask the chickens and rabbits how geometrically."

As soon as Wu Xuan said it, He Kuan was immediately angry:

"You can see why the market is so complicated."

Hearing this, Wu Shu laughed:

"Hehaha, if you can't answer, you can't answer, why roar here. According to the old man's opinion, it's better to leave as soon as possible. ”

"No, it's clear that you are deliberately playing tricks on me."

He Kuan was annoyed, what kind of chicken, rabbit, how many legs does this kind of butcher take care of, and it can be regarded as a problem?

Just when Wu Shu was complacent, Bailiyan was happy and blurted out:

"There are thirty-four rabbits and fifty-four chickens, dare to ask the master if it is right."

As soon as the words came out, Wu Shu was shocked:

"How does the son know?"

"This method is very simple, the chicken and rabbit have two hundred and forty-four feet, the chicken is two-legged, the rabbit has four legs, if each is half of the odd number, it is one hundred and twenty-two feet, at this time subtract eighty-eight, and the remaining thirty-four is the rabbit."

"Hah, big lottery!" Wu was overjoyed, and then asked: "There are ten people in the door, three people go out and two people come in, then two people go and three people enter, and finally two more people go and ask, how many people are in the door." ”

"There are eight left."

"Yes. The old man asked you again, there are ten trees at the bottom, nine trees on top, eight trees on top of nine trees, and so on, when the first wood is on top, there are several trees. ”

"Fifty-five."

Bailiyan's answer was like a stream, and Master Wu was overjoyed:

"The answer of the prince is very correct, go, follow the old man to the backyard to talk."

"No, this son has already answered the master's question, why did the master go back on his word."

"It's easy!"

Wu Shu patted his chest, turned around and said to Ximen Hua:

"Simon Deacon, what do you think of this matter?"

Ximenhua's face was ugly, and he said:

"Hey, you didn't ask anyone, but I lost a book to the old man, so how can the old man be good."

"The old man will give you a handwritten letter to explain the reason, presumably Liang Guoyuan will not be embarrassed by you."

"Either way. However, this son is very smart, why the pearl dust has not seen the brilliance before, it is really strange. ”

Ximen Hua wondered, approached Bailiyan and bent down to look carefully. I saw that the eyes between the eyebrows were deep and focused, full of aura that was not commensurate with his age. See here, Ximen Huadao:

"Your Royal Highness, the old man asked you, why did you ask for the "Literature of the Nations", and who taught the method of counting."

"There are books in the house, and there is a library in the palace, so you can enjoy them all, why is it difficult."

Bai Liyan said a lot of words, but she didn't take the old man's arithmetic problems into account at all, this kind of mentally handicapped problem below the first year of junior high school, where can it be rare for Wei Xian, who has obtained a degree in mathematics, it's a joke!

But then again, taking a sixth-grade arithmetic test for a nine-year-old child, or a child who has not received a modern education, is also too bullying.

[Note 1] Proton: In ancient times, princes and kings sent their sons to other countries as hostages in exchange for political benefits, and the title of hostages. This is where the term "proton" comes from modern chemistry.
