Li Zhi didn't take this matter seriously, it was just a pastime between brothers.

But he didn't know that this unintentional move had caused him a lot of trouble.

Temple of Manna.

His Majesty Li Er was busy reviewing the recital, but the eldest grandson walked in.

"Concubines, see Your Majesty."

His Majesty Li Er raised his head and said with a smile: "Why did Guanyin come here today?" ”

The eldest grandson has always advocated that the harem should not interfere in politics, so she pays great attention to this aspect, and generally rarely comes to the Ganlu Palace, even if she sends any food, she always sends the palace maid to come.

So His Majesty Li Er asked this question.

The eldest grandson walked to the side of the desk, put the playing cards in his hand on the table, and said softly: "Your Majesty, look at this?" ”

His Majesty Li Er flipped through it curiously, puzzled: "Where did Guanyin get this rare thing?" ”

The eldest grandson picked up the playing card and pointed to the numbers on it and said, "Your Majesty, these are all numbers, do you think it's much easier than my Datang's counting method?" ”

"It seems a lot easier, I wonder where it came from?"

The eldest grandson smiled and said: "Your Majesty, this is the master of the young slave brought back from a country, this is called playing cards, the numbers on it are called Arabic numerals, and these symbols are called English letters." ”

The first couple of Datang studied for a long time, and the two agreed that these Arabic numerals are of great significance to Datang's arithmetic and must be promoted.

"Guanyin, how about you give the promotion of this Arabic numeral to the young slave?"

For his son, His Majesty Li Er is very fond of him, Li Zhi has been smart and clever since he was a child, although he is only seven years old this year, he has the ability to never forget, and he only needs to learn anything.

In addition, he also has a master who was shocked by His Majesty Li Er, which simply made this most noble man in the Tang Dynasty a little envious and jealous of his son.

What makes His Majesty Li Er feel very sorry is that a figure like the scalper ancestor can't work for the Tang Dynasty.

"Is this too much pressure on the childish slave?"

Although the eldest grandson thinks that his son is very powerful, he will become a gentleman at the age of seven, which seems to be a bit too early.

His Majesty Li Er shook his head and smiled: "I see that this little guy is a big ghost, but he can do this thing." ”

After seeing that His Majesty Li Er really knew people and was good at his duties, he actually saw his inner strength through Li Zhi's weak figure, could it be that this guy had also practiced in a certain furnace?

"Yawn"

Li Zhi rubbed his nose and wondered, "Could it be that someone is talking about me behind my back?" ”

But he was soon caught up in a book in his mind, and everything else had to be sidelined.

This book is "Journey to the West", which the members of the Earth Traveler Alliance like to use to tell stories to their friends after crossing.

When reading the passage of Tang Xuanzang's birth, Li Zhi muttered: "This monk seems to have a chance that I have to explain, that monkey doesn't know if it really exists?" ”

In which plane Li Zhi was in his previous life, people were convinced of the existence of immortals, so Li Zhi thought that the characters in "Journey to the West" still existed, which was diametrically opposed to the cognition of the members of the Earth Traveler Alliance.

There is a factory called the Printing Factory in the Xinghai Science and Technology Factory, which is full of all kinds of books, and Li Zhi reads these books to pass the time when he has nothing to do.

In order to be able to understand these books, our classmate Li Zhi taught himself Hanyu Pinyin, so the books he read were all books that lived in Pinyin.

Thinking of what messy methods those ministers used to teach him to read and write, Li Zhi felt so speechless, there was obviously a simple way, how could no one find out, he felt sad silently for his peers.

He has the idea of reforming Datang education and contributing his modest contribution to Datang's children's education.

This idea will soon become a reality, because the attendants beside His Majesty Li Er have already come to the Lizheng Hall and are asking the nurse to inform him to go to the Manna Palace.

After hearing the nurse's words, Li Zhi got up and yawned, and followed the attendant to the Manna Palace.

He had also been to the Manna Hall before, and he knew what it was like, so now he wondered if his father had any problems that he couldn't solve and needed the help of his prodigy?

If that's the case, I'll reluctantly help him, who will let the family be their own son.

In Li Zhi's YY, the Ganlu Hall soon arrived, and after Li Zhi entered the Ganlu Palace, he saw at a glance that his father was kneeling with an old man on the desk to study something.

This old man Li Zhi knows, his name is Kong Yingda, and he is the thirty-second generation grandson of Confucius.

Hearing the name Confucius, Li Zhi wondered, how could there be such a name, could it be that he also had a younger brother named Diamond?

When he said this, Li Er and his wife almost laughed, but in the face of a little guy who didn't know who Confucius was, they couldn't be angry with him.

"The sons and daughters have seen their father, the emperor, and the queen mother, and they have seen the lord of sacrificial wine."

Li Zhi was thoughtful in etiquette at a young age, and people couldn't find anything wrong.

"Pheasant slave, come to me."

His Majesty Li Er hugged Li Zhi on his lap, and said with a doting smile on his face: "Have you ever learned the Arabic numeral pheasant slave?" ”

Li Zhi said proudly: "Of course, I'm afraid that today's Tang Dynasty will not be able to find anyone who knows Arabic numerals except for my master." ”

If tech factories can also be counted as people, then Li Zhi is not lying at all.

"Then the father ordered you to go to the Guozijian and give this Arabic numeral to all the gentlemen, is the pheasant slave willing to go?"

Kong Yingda also said with an earnest face: "Nine Emperor Princes, if you can teach the Arabic numerals to Mr. Guozijian, then you can contribute to the arithmetic of the Tang Dynasty." ”

"As a member of Datang, I am naturally willing to contribute to my Datang, and an Aalapo number is nothing."

I didn't expect Li Zhi to have such an awareness at such a young age, which made His Majesty Li Er and the eldest grandson feel very gratified.

So our seven-year-old genius classmate Li Zhi got the first opportunity to leave the palace, although he only went to Guozijian, but this also made Li Zhi feel very happy, and he could finally breathe the air outside.

Guozijian is next to the palace, and it will be there after leaving the palace gate.

Guozijian was established in the Kaihuang period of the Sui Dynasty and was originally called Guozixue. Tang Chengsui system, the first year of Wude (618) Tang set up Guozi School, with a school quota of 300 students, all students are children of nobles, and 24 teachers. In the first year of Zhenguan (627), Tang changed the name of Guozixue to Guozijian, and at the same time became an independent educational administrative body. There is a sacrificial wine in the prison, who is the highest educational administrator. There is one person and one main bookkeeper, who is responsible for specific matters such as students' academic performance and student status.

During the Tang Dynasty, one of the characteristics of Guozijian was that there were many foreign students, such as Goryeo, Baekje, Silla, Japan, Gaochang, and Tibet.

The establishment of Guozijian is a very important part of the imperial examination system, and the institutions under Guozijian also provide talents for the imperial examination.

There is a plaque on the top of the two thick red pillars, with the three big characters of "Guozijian" written on it, which looks very magnificent.

Inside the Guozi Prison are rows of houses with red to green tiles, and the sound of reading loudly reaches Li Zhi's ears.

Old Mr. Kong Yingda took Li Zhi to his room and said to him: "Nine Emperor Princes, you wait here for a while, the old man will go and call the gentleman who teaches arithmetic." ”

"Okay, Lord Sake, please take care of yourself, I'll wait for you here."

Li Zhi still respects the old gentleman Kong Yingda very much.

Kong Yingda's room was full of books, with pen, ink, paper, and inkstone on the table, as well as a copy of the Analects, which was handwritten by himself, and the handwriting was neat and powerful, which made Li Zhi feel that it was a pleasure to look at these words.

After a while, Kong Yingda came in with a gentleman, who was Xu Zhiyuan, who was in charge of teaching arithmetic.

"I've seen the Nine Emperors." Xu Zhiyuan bowed slightly to Li Zhi.

Li Zhi hurriedly said: "Sir, you don't have to be polite. ”

Kong Yingda said eagerly: "Your Highness, why don't we start now?" ”

For something that can inject fresh blood into the education circle of Datang, Kong Yingda naturally showed great urgency, which made Li Zhi feel that this old man was also quite interesting.

Li Zhi showed off his bag again, and took out a colorful book from it, which read "Arabic Numeral Teaching Tools".

The colored book cover simply blinded the eyes of Kong Yingda and Xu Zhiyuan, they had only seen a single color, such as blue, or black book cover, this kind of book has a variety of colors on the page, not to mention that they have never seen it, it is simply unheard of.

"Your Highness, where did you get this book?"

Li Zhi didn't care whether his master would sneeze in an unknown place, so he said casually: "This is naturally given by my master and his old man." ”

The ministers who have been in contact with Li Zhi all know that this Nine Emperor Prince has a mysterious master, but even His Majesty never says anything about the existence of this person in front of people, so they are very curious about Li Zhi, the mysterious master.

There are a lot of such books in the library in the science and technology factory, and as long as Li Zhi needs it, he can automatically print them in the printing house, but he can only take out one copy now, otherwise there is no way to explain it.

Li Zhi opened the pages of the book, and it was all in color, and the two gentlemen were dumbfounded.

"In fact, the introduction in this book is very detailed, and the two gentlemen can learn it by themselves by looking at this book, and they don't need me to teach you at all."

After explaining this sentence, Li Zhi put the book in front of them and let them learn it by themselves.

Seeing the serious appearance of the two, Li Zhi felt that he had taught the right person, so in order not to disturb the two, he walked out of Kong Yingda's room directly.

At this time, Guozijian's students were moving their bodies in the courtyard, and Li Zhi saw his cousin Changsun Chong at a glance.

Changsun Chong is the eldest son of Changsun Wuji, and Li Zhi, as the nephew of Changsun Wuji, naturally can't help but know Changsun Chong.

"Your Highness, why are you here?" The eldest grandson Chong said curiously.

Although Li Zhi should call himself his cousin according to his seniority, the eldest grandson Chong could not lose the courtesy of a monarch and a minister in front of Li Zhi.

"I came with Master Saisake, is my cousin out of school?"

Changsun Chong's personality is like a humble gentleman, and he always has a warm smile on his face.

"Well, I'll have to take an arithmetic class in a while."
