"Sir, want to add courses in the official school?"

Ying Zheng looked at Lu Yan's book, "Mathematics, history, law and morality...numbering is really important. Addition, subtraction, multiplication and division are popularized, and the calculation is changed into an abacus. Sir, what is this abacus?"

Arithmetic in this period has already been decimal and multiplication formulas. However, the calculation chips used to assist in calculations are much different from the convenience of calculations compared to abacus.

Lu Yan took out a wooden abacus, and the rectangular long frame was divided into two grids by a beam, with straight columns running up and down, and there were abacus beads on the columns, two upper grids and five lower grids.

"This is the abacus. In the decimal system, each column is the gear, one, ten, hundreds, thousands, and so on. This is an eleven abacus in my hand."

Ying Zheng looked at the wooden frame curiously and fiddled with it twice, "How to use this?"

"The five beads below represent one, and the two beads above represent five. When the bottom is full, clear zero, and a bead is drawn out above. When the top is full two five, clear zero and a bead is drawn out in the previous level."

While explaining, Lu Yan made a simple demonstration, 55=10.

Ying Zheng played on the abacus for a few times and was very interested. "Use pearls instead of chips, and go to one for five or ten for upshifts. This thing should be much better than chips. Let me give it a try. Sir, please make a question."

He shook his sleeves, exposed his hands completely, and stroked them to the edge of the desk, ready to perform calculations at all times.

Lu Yan opened his mouth and said, "There are 150,000 troops, and the battle will be damaged by 67,888. How much will it be left?"

Ying Zheng read while tying, "150,000, one in one in one in one in one in ten thousand, one in ten thousand, minus sixty-seven,888...the rest...there are eighty-two,112."

"Haha, sir, let's have another question."

“1358-256=?”

“1102.”

“7963-1586=?”

“6377.”

...

He played for a while but still felt unsatisfied. "I am not proficient in arithmetic, but I can also calculate quickly and accurately. This thing is in the hands of arithmetic, and it is extremely powerful.

Alas ~ Sir, what are you going to teach this history class?"

"The origin and development of the Huaxia race tells the world that we are actually a tribe."

"Huaxia people, we are all from the same clan. Hahaha, in this way, the six eastern countries are unable to sleep or eat day and night."

"They couldn't sleep or eat at first, and this had nothing to do with Lu Yan."

At this time, the idea of ​​unification has been reflected in many elite figures, such as Xunzi, Han Fei, Li Si, and Mencius, because this is their ambitions and ideals.

But it is impossible to say that the people of the six countries are eager for great unification. All countries have been established for hundreds of years, and the people are eager for peace, but this peace is at the cost of destruction of the country, and they cannot agree with it.

There is nothing Lu Yan has to worry about when Qin destroyed the six countries. He just needs to worry about how to prevent Qin from being killed by the sudden expansion of the ruling territory, so that the people of the six countries can accept the rule of Qin. This way of turning everyone into a clan from the source is undoubtedly a good idea and the first step.

Ying Zheng continued to ask: "Law and morality, law is a compulsory course in Qin State. What is the beauty of the morality that the teacher wants to teach?"

Lu Yan did not answer directly, but asked a sensitive question: "The king believes that the laws of Qin are harsh laws?"

"Don't you know that you use heavy sanctions in troubled times? Although our Qin Dynasty's legislation is strict, the country is prosperous and the people are safe. How can it be called a harsh law?"

"Lu Yan has a different interpretation of this sentence in troubled times."

"Sir, speak."

"The king said that Qin State has been legislating for a hundred years and the country is prosperous and the people are safe. Why did Qin State's heavy punishments clearly not change within the last month, but thieves are everywhere in the country?"

"This, let me think about it..." Ying Zheng's frown and thought for a while before letting go, "The law is guaranteed by the state's coercive force, and the state's coercive force is weak. Even if it is a heavy punishment, it will lose its deterrence to these bandits. Therefore, thieves dare to ignore the law and commit crimes."

Seeing that he thought so quickly, Lu Yan praised: "Yes, the so-called heavy dictation is a means of using heavy dictation in troubled times. What really scares the thieves is the ability of the country behind it. The legal system of Qin has been deeply rooted in the hearts of the people. As long as the Qin Dynasty remains unchanged, even if the law is relaxed, no one in the country dares to cause trouble.

Although the Qin Dynasty was strong at this time, it was not energetic, and severe punishments were the main reason. Lu Yan hoped to improve such laws bit by bit.

This is also to make plans for the future governance of the six countries. If the six countries are suddenly unified, the people will be anxious. If the laws are harsh, the people will be unstable; but if the six countries are relaxed, it will hurt the Qin people's hearts. It is best to gradually improve from this time, so that all people can be treated equally and demonstrate the hearts of a great country."

Ying Zheng was fascinated by the hearing and nodded frequently, "Sir, I am concerned about the long term, and I am taught. What are the differences between law and morality?"

"The law is to maintain the stability and stability of the country. It is a bottom line. If it touches this bottom line, severe sanctions must be imposed.

But this bottom line should not be set too high, otherwise all walks of life will lose their vitality.

Morality is a positive social trend recognized by the state and recognized by the people. The bottom line set by the law is the minimum morality. When a person's behavior is higher than this bottom line, morality needs to regulate them. The rule of law is the bottom line, and the rule of virtue is the two wings, complementing each other.

This is why Lu Yan decided to add an ideological and moral course."

Ying Zheng heard this long paragraph of Lu Yan and teased: "Hahaha, sir, I have taught Master Xun's etiquette and law to Qin State in a way, and said that he is not thinking about Confucian inheritance."

There is no need to say much about the influence of Confucianism on China. Later generations cursed Confucianism so much that it was bloody. But Confucianism truly hits human nature.

Humans are social animals. Human nature is born with a yearning for peace and order. In the relationship between people, the principles of integrity, friendship, etc. are recognized by humans.

Those who wantonly exuded the foul smell of human nature on the Internet never knew that it was because most people were good people that they had room for their own scum to do evil.

There is a very strange "hypocrite" saying that many people hate "hypocrites", saying that these people have the same mind and the same behavior.

But are there really gentlemen in this world?

People have desires in their hearts. Knowing how to control their own desires is a "hypocrite" and will they be despised?

Haha~ I wish all these people will meet are real villains.

The moral style advocated by Confucianism naturally has dross, but there are more active and useful parts.

"I just follow the law in the world. When Confucianism is educated, I just talk about the facts. The inheritance of Confucianism does not need Lu Yan to worry about."

"Mr. I have no selfish intentions for Qin, and I know it. But sometimes, in the whirlpool of power, these things are involuntarily."

Ying Zheng suddenly looked a little sad, Lu Yan was confused, "Master, what happened?"

"My grandmother and the Queen Mother told me about marrying a wife, and it seems that she intends to introduce you to a princess of Chu."

?The Empress Dowager Huayang!

Then wouldn’t I be transformed into a member of the foreign relative of Mi?

I'm dazzled!

Lu Yan didn't want this hot princess of Chu, but before he could refuse, Ying Zheng said another big thing.

"According to Zhong's father's plan, Qin State deepened trade ties with Qi State, and the King of Qi sent envoys to Qin, hoping to marry me."

"This is a good thing." Lu Yan responded subconsciously, just using this to balance the harem.

"Sir, after completing his studies in Xiaoshengxian Village, he is considered half a member of Qi. The King of Qi has also prepared a princess for you."

Lu Yan:...

I didn't say anything, I ran away from home immediately!
