Emperor Qin

The corpses on the city wall were quickly put down and restrained. Their families mourned and wailed under the wall. Name - Shangqing Yanjiang.

After successfully persuading the Queen of Qin yesterday, the name of this new Shangqing was spread all over the streets of Xianyang overnight. Countless people were asking who this god was, who was able to persuade the tyrannical King Qin.

Then I learned that this is an alchemist who came from the West on a tiger and came from the Weishui River. He can make extremely useful paper and knows the secrets of the heavens. Lai Ai's subordinates were doing things, but after the incident, Lai Ai was never implicated in the slightest. Instead, she was favored by the king. She is definitely a powerful person.

Yan Jiang became famous again, and countless people wanted to see him. Li Xin, who had the best relationship with him, was harassed endlessly because of this. dodge.

The person involved, Yan Jiang, left the palace early in the morning and went directly to the Imperial Historic Office in Xianyang City, which is in charge of the entire Qin State's classics and archives, and all the books he was looking for were found here.

The high-ranking officials in the office have gone to court, and there is only one censor who is in charge. Hearing that Shangqing brought Wang Yu here, he is so respectful that he almost kneels down to him—he is One of the people who pleaded for the queen mother yesterday was almost hanged on the city wall by the king, and today he took the initiative to change shifts and dare not go to court.

Yan Jiang went to comfort him twice, and seeing that he insisted on repaying, he didn't say any more.

This man was respectful and responsive to him, mobilizing the entire bureaucracy to find books for him.

Now the state of Qin uses big seal characters, which are like ghost charms. Yan Jiang has studied for more than half a year. Although he can recognize every word, it is very difficult to write. He needs to find a small official here to transcribe it on paper for him—— Li Chong will send someone to deliver paper to him every month, and now he has saved more than 1000 dollars, which is enough for copying.

But now the Six Kingdoms came to buy wine to congratulate, and there are many things in Xianyang City, and the censor couldn't stay with him all the time, so he found a very clever little official, who was seventeen or eighteen years old, with a delicate face, red lips and white teeth. His eyes sparkle.The censor introduced that his name was Zhang Cang. Although he was young, he studied under Xunzi and came from Qi with his senior brother Li Si. He was very intelligent and had all the books in the treasury.

Zhang Cang?Yan Jiang didn't expect to be able to catch such a big fish just by looking for a book. He couldn't help but put on a gentle smile like a wolf grandmother, and thanked the other party on the spot. He took the boy aside and asked, "I heard that you learned from Xunzi , still have an old relationship with Li Si? Why don't you go to work with Li Si Changshi?"

Zhang Cang, Li Sihan Fei's younger brother!Although not as famous as the first two, he is a well-known scientist. He revised the Nine Chapters of Arithmetic. He integrated mathematics into calendar measurement and social practice. In terms of social contribution, he is not inferior to the first two.

The young man was a little shy, and said earnestly: "Back to Shangqing, there are plenty of books in the Yushifu treasury. Cang has not completed his studies. He feels that he is not as good as his senior brother, so he wants to read more books, not seeking fame."

"Since you haven't completed your studies, why don't you continue to study at Xunzi?" Yan Jiang asked curiously.

"Back to Shangqing, my family teacher is old and weak, and it is difficult to teach and persuade. Therefore, three years ago, I dismissed my disciples and retired to the state of Chu. Go to Xianyang with senior brother." What Zhang Cang didn't say was that Li Si was very stingy, and he didn't have much contact with Lu Buwei after he got in touch with him. He is also a person with a temper, and the relationship between the two parties naturally cooled down.

"So that's the case, then I'll have to work." Yan Jiang took the young man back to the palace to fetch paper, and asked him to copy various precious books, while he himself wrote down some memories of geometric algebraic equations on paper.

Sure enough, after copying several books, Zhang Cang stood up and moved his body, and saw the magical symbols and formulas at a glance, and his curiosity was completely irresistible: "Dare to ask Shangqing, what is this word?"

"This is..." Yan Jiang just wanted to say that it was Arabic numerals, but when he thought that there is no such numeral in India, let alone Arabic now, he said with peace of mind, "These are the ten numerals I summed up for simplified calculations. I call them numbers, you see..."

Zhang Cang has a photographic memory, and he has learned ten numbers in less than a moment. After learning the calculation method taught by Yan Jiang, he was shocked by the convenience of this algorithm for a while, and forgot his responsibility to copy books. He himself is extremely talented in numbers, otherwise he would not have summed up the Pythagorean Theorem, and asked all the math questions he didn't understand before like a child.

These mathematical problems cover Fangtian (calculation of the area of ​​irregular polygons), corn (equal ratio exchange), decay (proportional distribution), Shaoguang (knowing the area to find the side length), quotient (finding the volume), and even loss (each Proportions), surplus (dividing apples), equations and the Pythagorean theorem, which were extremely advanced mathematics in the Qin Dynasty, but belonged to elementary mathematics in modern times, and could not stop Yan Jiang from sweeping.

The more Zhang Cang asked, the brighter his eyes became, and his whole body became excited, but mathematics is not something that can be done overnight, the more you ask, the more confused you become, and you feel that you have already reached the treasure mountain but you can only grab it and walk away. , I can only ask me in a low voice, can I ask you if I have any questions in the future?

"Of course." Yan Jiang smiled slightly, what is missing is a science talent like you to carry forward my knowledge, and it is impossible for King Qin to let you go if I let him go.

Zhang Cang was very satisfied, only then realized that it was getting late, and hurriedly wanted to leave.

"Now that the gate of the palace is closed, you can't get out. Why don't you just stay overnight." Yan Jiang knew how hard it is to find this kind of talent, so he was going to make a bigger move. Not only did he prepare a super delicious meal, but he also took him there. After looking at the starry sky, tell him that the elevation angle can be used to calculate the height, the angle of view can be used to calculate the distance, the stars can determine the mountains, rivers and national boundaries, and the numbers can tell the reality of a country...

Hearing this, Zhang Cang's heart was shaken: "Shangqing! I will ask for my resignation tomorrow. As long as you don't dislike me, I will stand by you from now on. When you say east, you never point to west, and when you look south, you never say north. I just ask my lord to give you some pointers when you are free."

Looking at the bright eyes of the other party, Yan Jiang pretended to be reserved and thought for a while before slowly nodding in agreement.

Zhang Cang was overjoyed, and when Yan Jiang was pointing at the stars, he couldn't help leaning on them, sticking his finger to see which one it was.

Just as he was talking, he saw a big bird fall and was caught by Yan Jiang swiftly.

The bird fluttered furiously in the servant's arms, looked at Zhang Cang on the left, and Yan Jiang on the right, looking extremely displeased.

"I chatted with you for a long time today, but I forgot to feed my little majesty, you go and rest first." Yan Jiang was busy with business, so he said cheerfully to Zhang Cang first.

Zhang Cang nodded in agreement, and went back to his room first.

Only then did Yan Jiang turn his head to comfort His Majesty, and said affectionately: "Baby~ I slept with Zhang Cang today, which is related to whether I can receive this apprentice, and you are already a big owl, you have to learn to live independently. How about you sleep on the lamp stand today?"

Maotouying was stunned by these words for a moment, he even forgot to thump, his eyes were wide open, as if his wife had just come home from get off work and heard the scumbag saying that he wanted to sleep with someone else so you went out.

Yan Jiang bowed his head and kissed His Majesty, took it back to the room, put it on the table, and put meat on it, and then continued to talk with Zhang Cang Bingzhu night, completely forgetting the day when he was still in love with Da Bird yesterday—he Not a good teacher, Zhang Cang is just the opposite, he can completely make up for his shortcomings, and his learning ability is extremely good, teaching him, his life will be much easier.

Your Majesty is so considerate, it must be understandable, um, just like Huahua before.

Yan Jiang found that something was wrong with Qin Wangzheng these days.

But I can't tell what's wrong.

The students he promised to select for him have already arrived, and they are all selected from various schools in Qin State, but Yan Jiang found that their thinking can be said to be very rigid-this is also understandable, there are schools in various places in Qin State, For people to learn various laws and regulations, and after passing the assessment, they will be sent to various places to take up positions and become basic civil servants in the Daqin countryside.

But because of this, their ideas are basically restricted by these regulations, and it is difficult to adapt. They have no choice but to help copy the book and get a rubbing. Diligent.

The first batch of pottery sutra panels have been fired and placed on the wall outside Xianyang City for rubbing. Although the paper is expensive, there is still an endless stream of rubbing every day.

You must know that books are treasures, they are not only expensive but also difficult to buy, and it is extremely difficult to copy them. For example, Zhang Cang is a very small number of people who can enter the examination and enter the government office. Most students can only repeat one or two books. Try to figure out, only the rich and powerful can be more qualified to choose which faction.

Because there are classics in every school, Yan Jiang has a very good reputation in all schools, saying that he has made great contributions to the world, and even many students in Xianyang have sent letters to the same school, saying that there are books to copy here, and the books will come as soon as possible.

Yan Jiang also set up a platform on the pottery board for the lectures and debates of various families. Although many people who talk nonsense will be spit down, there are also many people who have succeeded in making a name for themselves.

It stands to reason that King Qin should be very happy with this kind of development.

Where did his faint displeasure come from?

Are emperors so incomprehensible?

And Your Majesty, it's just that he didn't take care of him in time in the middle of the night, and he ignored him for several days, no matter how coaxed he was, it's useless to stay alone on an empty bed for several days, alas, this world-how impermanent.

"So it's best for you, Huahua, and I'll get you some mosquito-repellent incense." Yan Jiang stroked the chin of the big tiger under him, and looked thoughtfully at Qin Wangzheng next to him.

Huahua grunted contentedly, rubbed her head against her master, and wrapped him up in her body.

Qin Wangzheng raised his eyebrows slightly, and said indifferently: "Yan Qing, your widow in Sizhou Yutu is very confused, why don't you explain it to me?"

"Promise." Of course Yan Jiang agreed, "The king please show the picture."

"The widow still has something important to do. After the evening's work is over, Yan Qing can come to the bedroom to answer questions." After Qin Wang finished speaking, he got up and left, and calmly glanced at the big tiger.

"promise."
