A sudden heavy rain washed away the irritability of summer and the impetuousness of people's hearts.

When the rain passed and the sky was clear, the people of Yangzhou, who had been stuffy all summer, suddenly discovered: it turned out that unconsciously, the midsummer had passed, and the autumn was coming, and even the air had a trace of coolness.

The academy in Qili Village.

Xiao Shisan, who was dressed in a long robe, walked into the academy with a stack of brand-new textbooks and greeted the porter, and then he habitually stopped and looked at the words engraved on the shadow wall!

"Huh? Thirteen, all the printed books have been brought back? Someone passed by not far away, and when he saw Xiao Shisan, who was standing in a daze, he asked here with a smile.

Xiao Shisan came back to his senses violently when he heard this, and his young face was suddenly full of smiles, and he bent down and saluted the person who spoke: "Sir, the book has been brought back." ”

"Oh?"

The person who spoke was surnamed Song, and he was the first Confucian student found by Yin Can, who was over half a hundred years old, had good learning, and was good at studying.

It's just a pity that it was born at the wrong time!

Mr. Song has been studying hard for more than ten years since he was a child, and when he was preparing to finally soar into the sky in the examination room, he encountered the collapse of the Great Sui, the abandonment of the imperial examination, and the chaos of the world!

Seeing this, Mr. Song had no choice but to wait at home for the resumption of the imperial examination.

Who knows this, it's decades past! By the time the Tang Dynasty was established, he lost the spirit of his youth, and he only wanted to stay in his hometown and be an ordinary teacher.

"Can I take a look, then?"

Mr. Song walked over to Xiao Shisan and asked very sincerely.

In a pair of gentle eyes, there is no joke at all, there is just an equal treatment.

"Absolutely!" Seeing this, Xiao 13 smiled and nodded, then squatted down, put a stack of books on his lap, and handed over the top one with one free hand.

"Thank you!"

Mr. Song looked at the book that was still with the fragrance of ink, first gave a serious salute, and then took the book with both hands and looked at it carefully.

The book in his hand is not very thick, thin one, but the numbers and characters in it make Mr. Song very difficult to read.

That's it, it's the result of him auditing a few classes, if you don't listen, I'm afraid that reading this book now should be the same as reading a book from heaven.

"Hey, the back waves of the Yangtze River push the front waves!"

After flipping through a few pages, Mr. Song, whose eyes were a little circled, couldn't help but sigh in his heart.

Then I remembered that when Xiao Shisan and the others first came, my heart unconsciously tugged.

At the beginning, the judge of the academy, who rarely showed up, suddenly brought these dolls to the house, saying that they were the academy arithmetic teachers!

Hearing the news, all the gentlemen, including him, almost didn't go crazy on the spot!

Even if you're a court judge, you can't be such a child's play, right?

Just these little ghosts? Not even as big as the students in the academy, to be a teacher? Why?

Confucian Sheng You remembered that he should be the first to jump out and scold and oppose it!

In his heart, learning is always sacred, not to be defiled, let alone insulted!

Like that court sentence, just find a few people to be gentlemen, this is not only an insult to learning, but also an insult to those of them who do learning!

A bunch of fingers mixed with foaming stars pointed towards the court judge, and the court judge was not annoyed, but the teenagers were angry first, and they had to compete with them.

It stands to reason that it is normal to compete with this thing, it is nothing more than dividing the superior, and a group of their big men can still be afraid of a few children who have not dried up?

Draw out the road on the spot, and learn from the arithmetic!

Before a few teachers could discuss who would fight, the young boy in front of him had already asked a few questions, and then, everyone was stunned!

Some of them are Confucian protégés, and some are Mohist masters.

It's not that I don't know arithmetic, in fact, arithmetic is a must-have knowledge for all readers! But the question of the young man in front of them, they stared at it for a long time, and found that they couldn't even find the direction to answer?

At that time, there were still people who did not believe in evil, thinking that this was because they had the guidance of a master behind them! After all, it's just a few milk babies, even if you start learning from your mother's womb, how much can you learn?

So, one by one, the questions that they thought were difficult were thrown away!

But what everyone didn't expect: the answers to one question after another were thrown back at a faster speed! And there is no mistake!

Now, everyone is convinced!

Learning is sacred.

In the same way, learning is not to be faked!

After this small test, they found that the arithmetic knowledge of these teenagers far surpassed that of any of them!

Then they can be gentlemen, how can teenagers not be?

"Mr. Song? Mr. Song? A few calls floating in the air completely broke the memories of Confucius, and after he was stunned, he looked at Xiao Shisan in confusion.

"What's wrong? A baker's dozen? ”

"No... It's not a big deal, but I have a question I want to ask!

"Oh? What a question, you say! ”

Mr. Song responded very happily, Xiao Shisan saw this, smiled shyly, and used his chin to nun the shadow wall, and said, "Mr. Song, I heard that the words on this shadow wall were engraved by the court?" So what do they mean exactly? ”

When Confucian Sheng heard that this was the problem, he immediately breathed a sigh of relief, he was really afraid that it was a problem of arithmetic, and then he would be completely blind! Now since it's not a matter of arithmetic, that's easy!

"What do you mean by that?" Brushing his beard, Mr. Song asked with a smile.

"Yes, this sentence is a bit obscure!" Xiao Thirteen nodded repeatedly.

Mr. Song laughed again, he had been with these people for a while, and he also knew: Although these teenagers are extremely evil in arithmetic, they are not so exaggerated in other aspects, and it is reasonable that they can't understand those lines now!

"The soul that covers people's hearts is not knowledgeable, and the things in the world are not reasonable, but the reason is not endless, so its knowledge is endless! This sentence has a lot of meanings, and it is simple, that is, a person has the ability to know, and everything in the world always has a certain principle! It's just that because these principles have not yet been thoroughly understood, people's knowledge is very limited, and new truths should be explored! ”

Translating the meaning of this sentence for Xiao Shisan, Confucian Sheng is already familiar with this, because he has said these words many times.

Almost every new student, after getting started, will have questions about this line of text.

At first, Confucian scholars would also wonder why they had to engrave this sentence on the shadow wall.

But after reading it a hundred times, he realized that their science school was too different from the other colleges!

Not only the Four Books and the Five Classics are taught, but also arithmetic, mechanical science, and even medicine!

If you want to learn so many things well, you don't have a heart to actively explore, that's absolutely not possible! This line is written here to remind students that there are truths that have not been discovered in the world! If you want to find them, you're going to have to do it, boys!
