Fish swimming around the world

Arabic numerals, Yuwen Chengxin didn't have many questions about this strange name, but what she didn't understand was why such a strange number was used? Moreover, would it be better than the existing ones?

Jiang Fan went step by step, pointing to the first simple vertical line on the paper: "This is what you call one, this is two..."

Soon, the ten numbers were introduced, and Yuwen Chengxin was extremely smart and quickly remembered them all.

"Okay, next, I will teach you how to use it..."

For three hours, from the initial confusion, to the exquisiteness and fun, to shock and surprise, in the end, when Jiang Fan finished explaining the most basic addition, subtraction, multiplication and division, Yuwen Chengxin was amazed by the prince.

Jiang Fan looked at Yuwen Chengxin, who was standing there in a daze, puzzled: "Hey, hey...what are you doing?"

The next moment, Yuwen Chengxin suddenly knelt down on the ground: "Chengxin dares to ask, can I worship the prince as my teacher?"

Ah? Jiang Fan was stunned.

Yuwen Chengxin said: "This mathematics is unprecedented in ancient and modern times, and it is exquisite and incomparable. This is the supreme way. Your Majesty is a scholar of heaven and earth. Chengxin bows down to me. I beg Your Majesty to accept Chengxin and teach me mathematics."

"I... am not teaching you..."

Jiang Fan was a little confused.

Yuwen Chengxin raised her head, her eyes burning: "This mathematics is unprecedented in ancient and modern times, and it is exquisite and incomparable. This is a supreme way. Such a rare and unique learning is not something that an outsider like Chengxin can covet. Only by being included in the prince's school can I dare to learn it. Chengxin dares to ask the prince to help me."

After she said that, she bowed her head again.

Jiang Fan suddenly realized that the things he was accustomed to were incredible learning in the eyes of people in this world, especially the ancestor of all learning, mathematics. Compared with this era where only counting rods can be used, the mathematics he knew was simply incredible.

Thinking of this, Jiang Fan was silent for a while: "Indeed, my mathematics is very different from the secular world. Do you really want to be my disciple?"

"Chengxin is sincere, and the world will show it." Yuwen Chengxin said firmly.

"A glimpse of the whole picture, the prince's mathematics is profound and profound, Chengxin is very obsessed, please help me!"

Jiang Fan said: "I didn't expect you to have a good vision, well, mathematics must be passed down, I will accept you as a registered disciple, as for whether you can become a regular disciple, it depends on you."

I was very emotional, I didn't expect to restore my identity across time and space, but I didn't expect to change from a liberal arts teacher to a mathematics teacher.

Although Yuwen Chengxin had never heard of the word regularization, she fully understood its meaning. This was already a surprise, the prince actually agreed to include her in the sect, if it wasn't in front of the prince, she would jump for joy. Immediately kowtowed repeatedly.

"Thank you, Your Highness... No, thank you, Master!"

Jiang Fan smiled: "Speaking of which, you are the second registered disciple, and the glutton who moves stones outside is the first, and he is also your senior brother. You should communicate more in the future."

Yuwen Chengxin knew that the so-called glutton was the grandson of Marshal Meng, the son of General Meng Wu, and the brother of Meng Tian. He was from a first-class family in the Qin Dynasty. For a daughter of a merchant, being able to become a fellow disciple with such a noble family is something she dare not even dream of.

At this time, Jiang Fan also looked at this new disciple meaningfully. He was very talented. Not only was he extremely gifted in mathematics, but he also had a higher emotional intelligence. He took this opportunity to become his disciple? He was indeed a natural business genius.

Immersed in the new mathematics, Yuwen Chengxin almost forgot to eat and sleep, but his pale cheeks were actually glowing with a faint red glow.

Jiang Fan was even more surprised by his talent. This woman is a genius in business and mathematics. After just one day, Jiang Fan sighed that this is a true genius. His math level has been returned to the teacher after high school, and I am afraid that he can't teach for long.

Yu Wenchengxin, who is immersed in mathematics, is not respectful at all. She asks, questions, and discusses all kinds of questions. She is quick-witted, eloquent, and has a spirit of getting to the bottom of things. She grabs Jiang Fan and doesn't let go of a question. It seems that she has long forgotten that she is facing the prince.

But Jiang Fan is very pleased. After all, deep in his heart, he hopes that mathematics can prevail in the world.

After urging her to eat several times to no avail, he had to ask someone to send the food to the study, and shook his head and went to sleep. It's the fourth watch, it's terrible.

...

The work of the glutton Meng Yi is finally done. He came to find Jiang Fan with great interest.

"Master, the work is done. The craftsman said it's good. Would you like to take a look?"

"Oh? No need. Since the craftsman said it's good, it should be good. You've performed well these days."

Meng Yi leaned over with a drooling face: "Then... Master, can you reward me with a copy of "Romance of the Three Kingdoms"?"

"Go!" Jiang Fan glared at him: "If you want to read "Romance of the Three Kingdoms", buy it yourself."

Meng Yi said with a bitter face: "You have finished reading it. When will the new one be released? I am anxious..."

"There is no point in being anxious. The most important thing for you now is not to read novels. Next, you have to start your real studies."

"Ah?" Meng Yi was stunned. Jiang Fan picked up a book from the table.

"Is this... "The Way of War"? "Meng Yi was shocked when he saw the two big words on it.

Jiang Fan nodded: "This thing is suitable for you."

Meng Yi looked at Jiang Fan in disbelief: "Master...you mean you want to teach me "The Way of War"? "

He was so surprised. The empress only gave the complete version of this military book to four people - old commander Meng Ao, general Meng Tian, ​​general Wang Jian and the current military commander Gao Qi.

Jiang Fan said: "Why, don't you want to learn?"

Meng Yi knelt down immediately: "Learn! Learn! I will learn!"

Due to the strict order of the empress, except for those few people, no one else knew about "The Way of War", but he was there that day and heard the first chapter with his own ears. He was amazed.

He wanted to learn it too much. The old man had said long ago that this was a rare book in the world and could be called the ancestor of the art of war. Born in a family of generals, his love for martial arts and art of war far exceeded that of ordinary people. Meng Yi had longed to read it more than once. However, the old commander Meng Ao shook his head and said that this book of war could not be passed on without the approval of His Majesty. I don't know how regretful it is.

I didn't expect that the master would actually teach it to me today. The huge pie that fell from the sky knocked him unconscious at once.

"You...get up first!" Jiang Fan was furious. The reason for the clang just now was that the kid's head hit too hard, not only knocking over the chair, but also breaking a piece of the newly laid floor tile.

Meng Yi chuckled: "I will practice, I will practice..."

Jiang Fan lamented, this young man, who was always so fierce, had such a disciple, the Fei family...

"But..." He looked at Jiang Fan hesitantly: "Master, this is a forbidden book, His Majesty has a strict order that the people who get it cannot pass it on to others. If you want to pass it on to me, His Majesty..."

"Tsk!" Jiang Fan curled his lips: "The forbidden book is for other people, don't forget, this book was written by the master himself."

Meng Yi's eyes lit up. Indeed, "The Way of War" was written by the master. If he wants to teach it, His Majesty should not object. But thinking of the empress who always keeps her word and gives orders as strong as a mountain, he is still a little uneasy.
