"Ahem..."

Yuan Chang, who had just swallowed a mouthful of rice, was almost choked to death by Guo Jia's words. If that's the case, it is estimated that Yuan Chang will become the laughing stock of the crossing world. At that time, his epitaph will read: Yuan Chang, the word so-and-so, when he was eating in 190 AD, he accidentally got [ghost talent] Guo Jia to worship him as a teacher, and unfortunately choked to death. This is a warning to the traversers not to do strenuous exercise when eating.

Of course, Yuan Chang knew that Guo Jia didn't really want to worship him as a teacher, but he couldn't help but say it when he was excited. The reason is because Guo Jia wants to enrich himself. No way, Yuan Chang's arithmetic really made him unbelievable. If it weren't for the real thing happening right in front of you, no one would believe it.

"Feng Xiao laughed, such arithmetic is just a surface, if you want to learn, I will teach you, how to talk about apprenticeship. ”

After listening to Yuan Chang's words, Guo Jia was also slightly embarrassed. The words of apprenticeship just now were really said by him when he was excited, and even if Guo Jia really apprenticed to Yuan Chang in order to learn this arithmetic, it is estimated that Yuan Chang would not accept it. Yuan Chang wanted Guo Jia to work for him, and Guo Jia naturally knew that although he could still work for Yuan Chang after worshipping his teacher. However, because of the status of master and apprentice, it will be a little unbeautiful.

Whether it is Yuan Chang or Guo Jia's character, they can't stand that sense of restraint.

"The lord is really a miracle in arithmetic like this, but it's just a skin?" Han Sui listened to Yuan Chang's words, and felt that it was a bit too much? Those arithmetic masters here, seeing Yuan Chang's calculations, probably would cry and shout to worship him as a teacher, but Yuan Chang said that these were just skins? Han Sui was wondering whether he was too ignorant, or the world was too crazy.

Zhao Yun was also a little incomprehensible, of course, he was convinced of Yuan Chang's words.

In this way, Jia thanked Yuan Gongzi. ”

This time, Yuan Chang passed the test. Guo Jia naturally has no thoughts of leaving, but if he wants Guo Jia to completely surrender to Yuan Chang, he has a long way to go. As for what is written in many stories, a certain master who sees the protagonist and shouts that the lord is crooked, this kind of thing is obviously impossible to happen.

Even Cao Cao and Liu Bei, who are talent excavators, have to show their magic powers in order to subdue each other; Cao Cao is naturally reasonable, presenting facts, and showing his own heroic strategy; as for the big-eared thief, of course, he weeps bitterly, and then explains that he is a descendant of the Han family and is loyal to the Han family. In this way, there will be great talents who will take refuge in them.

Yuan Chang never believed that the tiger body was shocked, so he let others cry and shout to worship him as the lord, although sometimes he would crook Teacher Cang, Teacher Muto, but this kind of thing Yuan Chang never crooked.

Yuan Chang picked his teeth and said with a smile: "Everyone is full first, and then I will explain slowly, this kind of arithmetic is just a skin, three-year-old children can learn it quickly, and when the time comes, everyone will study and study together, even if there is nothing to do in the future, it is no problem to be a bookkeeper." ”

"Ahem..."

The four people who wanted to continue eating almost didn't follow in Yuan Chang's footsteps after listening to Yuan Chang's words and were choked to death. With such arithmetic, to be a bookkeeper, it is estimated that God will not be able to see the thunder smash him.

It seemed that Yuan Chang's arithmetic was extremely attractive, Guo Jia and Zhao Yun quickly finished the meal, and then sat in front of Yuan Chang neatly, waiting for his explanation. Even Dian Wei, who had a headache when he saw the words, sat there like a good baby. Dian Wei studied arithmetic so seriously, of course, not to be a bookkeeper in the future. Dian Wei learned arithmetic, naturally so that there would be no mistakes when distributing wine in the future, and if he got less, he would be able to calculate it.

If Yuan Chang knew Dian Wei's thoughts, he would probably immediately go out and kick out this guy with a head full of muscles.

Yuan Chang straightened his collar, cleared his throat, carried his hands behind his back, walked with his feet in a figure-eight step, and his chin was slightly tilted, which was similar to the image of some bricks and beasts in later generations.

"Before we learn arithmetic, we first have to learn something new, and these new things are ancient Indian numerals. ”

"Ancient Indian numerals?"

There was a hint of incomprehension in the eyes of the four of them, what was this ancient Indian number.

Yuan Chang's eyes were high, and there was an expression of "I knew you didn't understand" on his face, and he explained very majestically: "Ancient India is a country in the far west, which appeared earlier than our Huaxia, and there are two other countries that are ancient Babylon and ancient Egypt. However, they were finally annihilated in the long river of history, and only our China can still prosper forever. ”

Yuan Chang took a sip of water to hide his embarrassment, and then continued: "Ancient Indian numerals are easy to understand, they are a kind of numbers invented in ancient India, and their use is naturally for arithmetic, which is convenient and simple to use, and easy to understand. The invention of numbers in ancient India can be said to be a leap forward in the history of arithmetic. Of course, you may not understand ancient India, but when it comes to the Kushan Empire, you will know it. ”

"What, Kushan Empire?"

Kushan Empire, Guo Jia naturally understands.

Since Zhang Qian of Emperor Wu of the Han Dynasty sent an envoy to the Western Regions, and the customs and customs of the countries in the Western Regions, as well as intelligence flowed into the Central Plains, everyone more or less knew some of the situation in the Western Regions. It is rumored that the Kushan Empire was as powerful as the Han Dynasty, along with the Rest Empire and the Roman Empire. The Roman Empire was separated by the Kushan Empire and the Sabbath Empire, so not much is known. However, the merchants of the Kushan Empire and the Anxi Empire often went to the Central Plains, so they naturally knew more about these two countries.

However, what does this Kushan Empire have to do with ancient India? As a think tank, Guo Jia faintly understood.

"Ancient India was the predecessor of the Kushan Empire, thousands of years ago, there were many dynastic changes in the middle, and now it is the Kushan Empire. To put it simply, just like our Huaxia, from Xia, Shang, Zhou, through the Spring and Autumn Period and the Warring States Period, then Qin, to the current Han Dynasty. Ancient India, on the other hand, was a country that appeared earlier than our Xia Dynasty. ”

Sure enough, Guo Jia secretly exclaimed in his heart. Although he had vaguely guessed it, Guo Jia's heart was still a little shocked.

Guo Jia felt a little pity in his heart, what a prosperous country should have been in ancient India, which invented the ancient Indian number, but it was annihilated in the long river of history. However, Guo Jia can also understand. Just like the Han Dynasty, the countries in the Western Regions that Emperor Wu of the Han Dynasty fought did not dare to step on Mahelan, but now, the border fortress is often invaded by foreign races, and the imperial court is powerless.

This is the case with the change of dynasties.

It is precisely because of this that Guo Jia has never had the idea of reviving the Han family in his heart. The Han dynasty has reached the point of decline, and even if it is revived, it will only bloom like fireworks for a while, and it will eventually die. This was true of the Shang Dynasty, the Zhou Dynasty, and the Han Dynasty would be no exception.

Therefore, in Guo Jia's heart, he just wants to find the master he expects and create a new dynasty. Even if he is not famous, it is enough for him to show what he has learned.

"Okay, now that you know what ancient Indian numerals are, I'm going to teach you what ancient Indian numerals are. ”

After Yuan Chang finished speaking, he picked up a brush and wrote on the paper, "0,1,2,3... 9" These ten numbers.

"Don't look at the little ten numbers, but they can be combined into all kinds of numbers, and the variety is breathtaking. ”

So, under the curious eyes of the four people, Yuan Chang began to explain the ten numbers.

Yuan Chang believes that when he explains mathematics to the four people, it will form a prairie fire, and eventually spread to every corner of Huaxia, and Huaxia will also lead to a new page because of his move. Perhaps Yuan Chang will rule the world in the future, and his dynasty will be replaced. However, the influence he made will make China usher in a different history.

Yuan Chang never doubted this.
