Daqin started with offering immortal medicine

Li Yang couldn't laugh or cry.

However, fortunately, he is used to being shameless, not only does he not feel blushing, but he is also a little proud.

"Zhang Cang, in mathematics textbooks, you should promote this vertical calculation method!" Li Yang confessed.

Zhang Cang hurriedly cupped his hands: "Here!"

At this time, Li Yang took the paper with the calculation formulas listed earlier, and next to each calculation formula, listed a calculation formula with Arabic numerals.

"My lord, what kind of symbol is this...?"

Zhang Cang asked with a frown when he saw the numbers written by Li Yang, as well as symbols such as plus sign, minus sign, multiplication sign, division sign, and equal sign.

Li Yang was not in a hurry to answer, but wrote the Chinese characters zero to nine in the blank space of the paper, and added their Arabic numerals below the Chinese characters.

After writing everything, he put down his pen and said to Zhang Cang, "This is a simplified number invented by Benxiang. These numbers correspond to zero to nine. Look, it is very simple, and they are also easy to use in vertical calculations." Is it more convenient?"

After Zhang Cang listened to Li Yang's words, he naturally saw the superiority of these simplified numbers at a glance. He looked at Li Yang in surprise and asked, "My lord, this...is this also your invention?"

Li Yang thought about it. Arabic numerals were invented by an Indian scientist in Baghdad in the 3rd century AD, but...now that he wrote it in 209 BC, it is naturally not an invention of India.

Ever since, Li Yang admitted again brazenly: "That's right, when I was a child I found Xiaozhuan to be complicated and difficult to write, so I used them to replace Xiaozhuan numbers when I was very young."

"what?"

After Zhang Cang heard this, he was amazed again: "I never thought that my lord would be so extraordinary when he was a child! Next time, I admire you."

Li Yang waved his hand: "It's just a trivial matter, it's not worth it!"

When Zhang Cang heard this, he straightened his heart, Prime Minister Zhong is really a humble person.

In his opinion, people in the world say that Prime Minister Zhong is frivolous and conceited, because people in the world don't understand his talent. If they really understand his talent, they will find that Prime Minister Zhong's wild words in the past can only prove the world's Just ignorance.

In order for Zhang Cang to experience the superiority of Arabic numerals more intuitively, Li Yang also wrote three-digit numbers, four-digit numbers, and five-digit numbers to let him understand that it would be extremely convenient to use these Arabic numerals for mathematical applications.

Zhang Cang, who was amazed, quickly pointed to those plus and minus signs and asked: "Then what numbers are these?"

Li Yang shook his head: "This is not a number, but a symbol. This is a plus sign, this is a minus sign, this is a multiplication sign, this is a division sign, and this is an equal sign. With these symbols, you can formulate calculations. .Like, look at this..."

This discussion is a whole day.

Li Yang discusses all the mathematics of later generations, from the shallow to the deep, with this ancient man, and Zhang Cang is stunned for a while, wondering if the person in front of him is not a human being, but a god.

In short, after a day of discussion, Zhang Cang just fell to the ground and worshiped.

Of course, Li Yang also told him that these simple numbers should be promoted in the textbooks with symbols, calculation formulas, and vertical formulas.

Yes, Li Yang wants to compile a primary school mathematics book that will be exactly the same for future generations!

Because mathematics is very important, it will promote the progress of various subjects such as biology, chemistry, astronomy and so on!Therefore, the number of homework must be strictly required.

Fortunately, Zhang Cang is really a math genius, and he knows it all.

Li Yang has no worries about the mathematics textbooks.

Chapter 141 The Chinese Nation

Under Li Yang's guidance, the Education Department quickly got on the right track, and the textbooks for the three subjects were also being compiled.

Originally, Li Yang wanted to invent simplified characters and pinyin, but he thought that the time was too tight, so it was difficult to do it in a short time, so that teachers from all villages and pavilions could master it.

Just imagine, even the teachers in the township pavilions who teach students are not proficient in the newly created simplified characters and pinyin. How can you ask them to teach students with such textbooks?

Therefore, Li Yang decided to set up a special writing reform group in the future, and then let this group master simplified characters and pinyin first, and finally let this writing reform group organize public teachers in various counties and counties for advanced training, and then let the counties and counties further study Teachers, go back to their respective counties to teach other teachers.

In this way, simplified characters and pinyin can be promoted smoothly.

Under Li Yang's instruction, the content of the first lesson of the Chinese textbook is: I am from Qin, I love my country, we share the same blood, and we are all descendants of China.

The Huaxia tribe is of Yanhuang blood, and has been unified into the Huaxia Tribal Alliance since the time of the Yellow Emperor.

The earliest history of civilization in China can be traced back to the Dadiwan civilization and Peiligang civilization in the Yellow River Basin 8000 years ago. Zhuanxu (Black Emperor), Xuanyuan (Yellow Emperor), Shennong (Yandi), Diku (Gaoxin), Yao, and Xia Yu.

"Descendants of Yan and Huang" was a very honorable name in ancient times. Many powerful people among ethnic minorities scrambled to get involved with Emperor Yan and Huang. If anyone went to the ethnic minorities and said that they were not descendants of Yan and Huang, they would definitely copy the guy and beat you Beat up so hard that even your mother doesn't know you.

In fact, for thousands of years, the concept of post-Yanhuang has long been a cultural concept that transcends ethnic groups. Therefore, there is nothing wrong with saying that everyone is post-Yanhuang. This is the result of many years of struggle by many ethnic minorities.

Therefore, in Li Yang's view, there is absolutely no need to subdivide the ethnic groups in the Great Qin. Bloodline, Huaxia clan.This is also more conducive to uniting people's hearts, and it is even more beneficial to future generations.At that time, Huaxia was one nation, there was no distinction between high and low, and there was no preferential welfare policy. There would be no conflicts among Chinese people because of their ethnicity, and everyone was treated as equal.

Such a politically correct textbook can naturally be highly appraised by Emperor Yingzheng.

It can be said that this kind of teaching material is what he dreamed of and used to educate the minds of the people all over the world.

Not only do border countries need to be unified, but people's hearts and minds must also be unified, and the nation must be unified even more.

Of course, other ministers would not dare to object to such an "excellent" teaching material. If anyone opposed it, they would end up just like those ministers who opposed the reform of the new law. They would be pulled out and cut down.

And just when the compilation of the textbook was almost finished, at the same time, several major events also happened in the military and political affairs of the Great Qin Dynasty.

One is that Nei Shi Teng retired and returned to his hometown, Han Xin officially took charge of the post of lieutenant of the capital garrison, and Zhou Bo was the deputy general.

Second, the 30 troops guarding the border gates of the Great Wall, under the command of Wang Li, became a general with heavy troops guarding the border.

The third is that Meng Tian was transferred back to Xianyang and served as a Taiwei to take charge of the military and political temple.

The position of Taiwei is the highest military officer in the whole country. This position has been vacant before. Now that Meng Tian finally takes this position, it is well deserved.

Kylin Hall.

Today is Meng Tian's first early court as Taiwei when he returns to Xianyang.

"Meng Tian, ​​is the frontier still peaceful?"

Ying Zheng finished discussing the government affairs in the early court, and turned to Meng Tian to learn about the situation in the frontier.

Meng Tian said: "Your Majesty, there are 30 soldiers of our Qin army guarding the frontier, no one dares to offend! What's more, now that the Huns have killed their father to stand on their own feet, their internal political instability is nothing to fear."

"Well, it's good to be worry-free." Ying Zheng nodded, in a good mood.

But at this time, Li Yang frowned slightly.

Because he heard a very familiar name, Mouton.

Mao Dun Shanyu, he was the first time in history to unify the northern grasslands and establish a huge and powerful Xiongnu Empire. He is a talented military strategist and military commander among the Huns.

In history, he first destroyed the Donghu and expelled the Yuezhi, thus eliminating the threats from both sides.

Later, he led the Huns to conquer more than 20 countries including Loulan, Wusun, and Hujie, and controlled most of the Western Regions.In the north, they conquered Hungao, Qushe, Dingling, Gekun, Xinli and other countries, and in the south they annexed Loufan (now northeast of Shanxi) and the territory under the jurisdiction of Baiyang Henan King, and reoccupied the land south of Hetao.The Huns lived in a vast area starting from Yinshan Mountain in the south, Lake Baikal in the north, Liaohe River in the east, and Congling Mountain in the west. big nation.
