Chapter 340 The Last Lesson ([-])
Inner Shutang Bookstore.

Sun Dan smiled and pressed his hands down. Before he could speak, a student on duty shouted, "Sit down!"

The thirty or so students in the class did not sit down, but all stared fixedly at the beloved teacher.

There were still tears streaming down Chen Hong's face, and through the light of his tears, he saw that the eyes of other students were all red.

Probably aware of the strangeness of the students, Sun Dan said in surprise: "Why don't you sit down, let's all sit down, let's start the class."

At this time, all the students sat down at the same time, but Chen Hong was still standing there, his heart was in a mess.

Sun Dan still did not sit on the podium as usual, but walked slowly with his hands behind his back, "Chen Hong, what's wrong with you?"

Now Chen Hong didn't care about people discovering his special relationship with Sun Dan, and asked loudly: "Sir, I heard that you are leaving us tomorrow. Is it true? We have been with you for so long. I admire learning very much, and I am about to learn from you the real ability to save the country, but you...but you..." In addition to sadness, Chen Hong also has a kind of anger of being abandoned in his heart.

"So that's how it is!" Sun Dan smiled gently, and looked at all the students: "You all already know it!"

No one answered the question, and everyone looked at Sun Dan sadly.

Chen Hong wiped his tears with his fist, and continued to question: "Sir, you should answer our question."

Sun Dan's expression was still as calm as usual: "Yes, students, sir, I will take the examination tomorrow, and this examination will last for nine days. Regardless of whether I am a Jinshi or not, the imperial court has other arrangements for me. Today is my last time. I have given you lessons, haven’t I told you before? After you finish your studies, you will all hold certain positions in the palace and serve the country. As a qualified national civil servant, you should have three elements: publicity, loyalty , Capable. Public means to be dedicated to the public and upright; able means to have a certain ability to work; loyal means to be loyal to duty, loyal to the entrustment of the imperial court, and loyal to the expectations of the people. Since the imperial court has a task for me, sir, naturally I have to obey orders , This is also loyalty to the country and loyalty to duty. As a teacher, you should set an example. Chen Hong, please sit down."

Sun Dan walked up to Chen Hong and put his hand on his shoulder.

The resentment in Chen Hong's heart has not been eliminated, but he still sat down, as if there was an irresistible force in Mr. Chen.

Sun Dan looked around and said to everyone: "I originally arranged a class of "Interpersonal Relations" today, but unfortunately I have to leave tomorrow, so there are no restrictions on subjects today. Let's change it, you guys You can ask any questions, and the master will answer them on the spot. I hope you can sort out the questions that have arisen from previous studies, I don’t have much time.”

"Yes." The students answered at the same time.

This is the last class!

Chen Hong's heart was agitated, he tried to sort out the knowledge he had learned from Sun Dan in the past period of time, but after sorting it out for a long time, his heart was still disturbed, as if everything was so clear, and everything seemed to be so chaotic. Just can't figure it out.

Damn, this is the last class sir, what should I ask?

"Interpersonal Relations", God, I am still the one who has a bad temper, and I still don't know how to get along with others; the official document writing, during this period of time, I was in the ceremonial supervisor, and I was approved on the memorial every day, but it can be summed up as "accurate" ", "Again", "Got it" a few words.Arabic numerals, four operations?Poor thing, I only know chickens and ducks in the same cage now, and some students have already learned the Pythagorean theorem and elementary geometry; as for elementary physics, how is buoyancy calculated...

Some students have already started to ask questions: "Sir, may I ask the historical records that Emperor Yang of Sui Dynasty was a tyrant with great achievements, but the Grand Canal he dug has been used to this day, and it is the main hub connecting the north and the south. If he only relies on this one item, he has It can be called a generation of Mingjun. But why did he brazenly launch an attack on Goryeo despite the exhaustion of national strength, so that the country was destroyed and died?” ——This is a historical question.

Sun Dan: "Everyone knows that the Sui Dynasty's national power at that time could no longer sustain a national war, but even if Emperor Yang of Sui did not attack Goryeo, wouldn't Goryeo not attack Sui Dynasty? Emperor Yang of Sui was just preemptive. As for Emperor Sui Yang commented in history, I personally think that any one of the things he did alone could make him a wise emperor of the generation, but it is a pity that he did these few things together, which is the reason for the demise of the Sui Dynasty On the surface, it seems that Emperor Yang of the Sui Dynasty was overjoyed. But the root cause is that the centralization of power in the Sui Dynasty was not enough, and there were still a large number of powerful and clan forces in the local area, so that the court could not accurately calculate whether the country's financial resources and manpower It can support one national project after another. The death of the Sui Dynasty was due to the weakening of the central power and the strength of the local power."

Another person asked: "Sir, you said in class before that to calculate the squareness and volume of an object, you can multiply the three numbers of length, width, and height. This method is naturally very useful for calculating geotechnical volume." , but if we encounter an irregular object, such as a large rock, how do we calculate its volume?"——This is basic mathematics.

Sun Dan: "There is also a good way. Put the stones into a pool full of water, and open a water outlet in the pool. Put the stones into the pool, and the water will overflow. The volume of the overflowing water is The volume of this irregular stone can be easily calculated by filling the overflowing water into a regular container."

"Ah, this is a good idea, thank you, sir." The student who asked the question suddenly realized, and felt joy in his heart.

……

I don't know how long it took, but the time passed by every minute.

The students asked a variety of questions, all over the world. Some people even asked the eunuchs in Sun Dan's palace how to take care of themselves because they were semi-yin and could not stand the cold in winter.

And Sun Dan did not refuse anyone who came, and answered them one by one.In fact, the weird and unsolvable questions that seemed to the ancients were common sense to a modern person like him. Besides, what kind of questions could not be answered by relying on the huge database in his mind?

It was at this moment that the students finally understood how profound the master's knowledge was.

Chen Hong's heart was still flustered. Looking at the gentleman walking around in the study, he realized what a precious academic master he had met.It's a pity that I wanted to please Huang Jin at the beginning, so I opposed Mr. Sun everywhere, so I didn't study hard.By the time you realize the value of your husband and want to learn the real skills, it will be too late.

Sun Dan walked up to Chen Hongming again, and said: "It's almost time, all the students have already raised their own questions, and you are one more short. It's already noon, Chen Hong, if you have any questions, please tell me quickly, wait After I answer your question, get out of class is over."

"It turns out that this lesson is over, time flies!" Chen Honghong was startled, he stood up abruptly, and said excitedly: "Sir, Chen Hong will ask you one last question. You have taught us so much , teach everything, and don’t stick to the Four Books and Five Classics. But after learning so much miscellaneous knowledge, what kind of person does the master want to educate us into, or what is the purpose of our learning so much? Not to mention cultivating for the country. In terms of talents, even if we change to another student, according to our quality, we can still succeed."

Chen Hong asked excitedly: "Sir, what kind of person do you want us to become?"

All the students fell silent, and Chen Hong's question spoke out their aspirations.

Sun Dan was silent for a moment, looked at Chen Hong, and said quietly: "I want you to become a real person."

************************************************* ***
In the prison of the Ministry of Criminal Justice, Master Gu was still laughing loudly: "Strange talk, how can a small person become the senior of the inner school? Lu Fang, I think you, a little eunuch, still have a little knowledge, and you don't want those annoying people. I am a eunuch who knows some words of sages. But after reading a few books, your knowledge has improved, so why don’t you know how to be a human being? You don’t even want the minimum of shame. Juren... Haha, Are you qualified to be a senior? You don't know how to blush when you tell a lie?"

Master Gu laughed, and other people in the prison also laughed, and said: "Yes, yes, eunuchs are unbelievable. They don't even understand the basic system of the court, and they come here to talk big. Listen to him His teacher, Sun Dan, is quite knowledgeable about the commentary on the "University" that he read just now. However, if this little eunuch wants to put money on his teacher's face, he shouldn't lie to others by saying that he is the senior of Neishutang, right? The seniors of the Neishutang are all bachelors of the Hanlin Academy, and I think it’s crazy to want to be a bachelor for such a small person.”

At this time, if it was Chen Hong who heard someone say that about his mentor, he would have jumped up and yelled at other people in the prison.

But unlike Chen Hong, Lu Fang had a calm temperament. He still sat upright on the ground without explaining. He just smiled sarcastically and said, "You are in this five-foot-square-inch area. I’ve been locked up for a long time, and I don’t know how big the sky outside is. Hey, look, there’s a five-foot green brick floor here, and there’s only a one-foot-square transom above the head, as if you’re in a well!” He dragged The voice sang a passage from "Huansha Ji" composed by Zhanbu: "Those who can't speak to the sea like a well frog are stuck in emptiness; those who can't speak to ice in summer are obsessed with time; Those who can speak in the Tao are not good at teaching! Although my teacher was born in Juren, his academic articles are all top-notch in the world. It is also because of this that he was appointed by His Majesty for his fame as a teacher in Neishutang. In my opinion, Compared with your master's knowledge, those bachelors of the Hanlin Academy are simply chickens and dogs, not worth mentioning."

This sentence hit a wide range of people. The people in the prison were silent for a while, and then broke out suddenly:

"What an arrogant eunuch, to talk to us like that!"

"What the hell, who here is not a Jinshi, granted Jinshi, and fellow Jinshi, who has not been a magistrate, who has not read sage books for many years, and they are getting university in front of us?"

"I think the "University" that Sun Dan just annotated in his mouth is quite satisfactory, and there is nothing surprising about it." Master Gu said loudly: "For anyone, just calm down and study this book repeatedly for ten or eight years. I can figure it out. I think your mentor is just a rotten scholar. As for why he was appointed by the emperor, ha, I understand. He has a eunuch like you as a student, so he naturally goes with eunuchs on weekdays It’s close. It’s probably because you went through your eunuch’s door before you entered the inner study hall. This is a disgrace to scholars, and Gu Tai despises it deeply.”

Mr. Gu, whose surname is Gu Mingtai, is also a person who can speak, and continued to shout: "Reading a few books of sages is not a skill. What is the purpose of reading, isn't it just to be an official? If you only know how to read dead books, you don't know how to govern the country. Even if you become an official, you will still be a mediocre official."

"Faint official, mediocre official?" Lu Fang sneered: "Master Gutaigu, when you were in the Yamen of the Yellow River River, the state allocated so much money for river defense every year, but what did you and your boss do? Floods break the embankment every year, aren’t you just a stupid official?”

"You... what do you know about river defense?" Mr. Gu was at a loss for words when Lu Fang talked about his shortcomings.

"I don't understand, but my husband understands. Although he is a juren, in terms of river defense, he is much more proficient than you, an official of the river yamen." Lu Fang read aloud: "Pass water to the river If the river meets the Huai River, then the Huai River is governed by the river; if the river and the Huai River enter the sea together, the river and the Huai River are governed by the sea... The Yellow River is the most turbid, and it is measured by fighting. The sand occupies the sixth place... build and draw water, attack the sand with water, but in one year the two rivers will return to normal, the sand will sweep the water deep, the seaport will be opened up, all the fields and huts will be returned to their own businesses, and the national economy will be unimpeded..." He He began to recite Sun Dan's works again.

Suddenly it is a river governance strategy.

When Lu Fang first read, Gu Tai still had a sarcastic smile on his face, but the more he listened, the more frightened he became, until the smile on his face froze, and his heart was like a thunderbolt.

He has been a river official all his life, so he couldn't hear what Lu Fang was reading.

When the former Hedao Yamen was an official, the Yellow River and Huaihe Rivers were decided every year.As an official, he can only try his best to build dams and plant big trees in his promotion.But the dikes and dams are repaired every year, and they are so blocked that they fill themselves in the sky prison.

After being in prison for so many years, it's not that he hasn't reflected on what he did in office.When it comes to incorruptibility, he is still a person who does not eat black money in Hedao Yamen, a place where the money is like a sea. They all moved to the embankment and lived there for a month.

But even so, why can't the water be managed well?

In this article, Sun Dan put forward many new insights, such as flushing the river with water to slow down the silting of the Yellow River, which made Gu Tai's eyes brighten, and he murmured: "I used to just blindly build dams, But as the dam goes up, within a year, the sand will silt up, and the water will follow. Then, we have to continue building the dam. Endless, endless...why is it endless..."

No one spoke anymore, and everyone in the prison was knowledgeable, and they all listened attentively to this river control strategy.

This article is very long, tens of thousands of words.It was impossible for Lu Fang to finish reading all of them. She only recited for a while and then stopped.

Gu Tai said urgently: "Little eunuch, why don't you read it anymore. Who wrote this article, who wrote it, is it so evil?"

Lu Fang: "Great talent, you finally admit that the person who wrote this article is a great talent? You want to hear it. After you get out of prison, go buy a book and read it yourself."

Gu Tai also didn't care to argue with Lu Fang, saying: "People who can write such practical articles are naturally talented, and Gu Tai admires them. Buy a book, what book to buy, who wrote it?" He continued to ask.

Lu Fang finally laughed out loud, with tears rolling down his eyes: "This article is from the "Rizhilu" written by my mentor Sun Dan, and the title is "Two Rivers Guanjian". Today is the last lesson for Mr. It's a pity, it's a pity, but my incompetent disciple can only recite his old man's words in prison, and can't see his voice and smile. This is the last lesson!"

In fact, "Two Rivers Guanjian" is the work of Pan Jixun, a famous river ruler in the late Jiajing period of Ming Dynasty, and this book was later included in "Siku Quanshu".At the beginning, Sun Dan came across this book on the Internet and thought it was a bit interesting. Through this book, he could intuitively understand how the ancients mobilized national power to fight against natural disasters, so he downloaded it into the hard drive.

When copying "Rizhilu", Sun Dan simply added this "Guide to Two Rivers" into it.Anyway, "Rizhilu" is an encyclopedia-style work. The strategy of river control is beneficial to the country and the people, and it should be published for sale so that more river officials can learn it.

Gu Tai stood up abruptly, and bowed his hands deeply to Lu Fang: "Gu Tai just made a slip of the tongue and offended Mr. Sun. After seeing Mr. Sun Jingyuan's knowledge, Gu Tai realized that he was just a Xia who didn't know anything before. insect!"

Lu Fang accepted Master Gu's salute calmly, and nodded: "It's not Lu Fang who received the gift, I received this gift on behalf of Mr."

Gu Daren said: "With Mr. Sun's knowledge, I naturally received Gu Tai's gift. It's a pity that I am in prison and cannot see Mr. Jingyuan's demeanor. This is really the greatest hardship in the world!"

Everyone in the prison sighed: "Unexpectedly, Sun Jingyuan is proficient in the four books and five classics, and is also so proficient in river affairs, what a great talent!"

Gu Tai asked again: "Mr. Sun said in his book that trees should not be planted on embankments, but trees are fundamentally useful for fixing sand and binding soil. Why doesn't he agree?"

Lu Fangdao: "It is said in "Two Rivers Guanjian" that most of the fast-growing trees in the Lianghe River Basin are poplars and black locusts. These trees have a short growth period and can become useful in three years. Unfortunately, because they grow fast, they are also easy to rot. Once the tree roots rot, the river embankment will also decay."

Only then did Gu Tai suddenly understand: "Hey, why didn't I think of this place before."

Lu Fang smiled, and was about to continue chanting, when a jailer walked in and said loudly: "My lords, stop making trouble, it's noon, save some energy for eating!"

"It's noon, sir's class is... over!" Lu Fang's complexion changed, she suddenly spit out a mouthful of hot blood, and cried bitterly: "I wish I could serve by your side, even if I die, I will be willing."
