To the east of Peng Lize (Poyang Lake) in the north of Yuzhang County, the river flows quietly in the valley surrounded by mountains, and the humble mountains contain huge reserves of copper ore, which Cao Shi called Dexing Copper Mine.

This is Wei Changjun's fourth year of busy work in Dexing Copper Mine, from the initial unaccustomed to the hot and humid climate, he slowly changed to know what season is the rainy season, when the wind direction changes, and also learned to maintain the body from the local Han people.

Wei Changjun was rummaging through the materials to study the technology, he had a well-staffed team of prospecting, mining and smelting staff, and a number of prospectors from Shaofu gathered in the humble mountain camp, and they used their sweat and wisdom to study new mining techniques.

The scale of Dexing copper mine is very large, the proven reserves are estimated to be 30 billion catties (15 million tons), the unproven underground reserves can not be estimated for the time being, and the open-pit ore vein mining is not difficult, especially the popularization of iron tools makes the mining industry flourish in the era of digging underground deposits is not a dream, the difficulty lies in the deeper mining technology.

As early as the Shang Dynasty popularization of bronze tools, the technology of mining ore has been constantly improving, from the Shang Dynasty before the excavation of 20 meters deep deposits, to the early Han Dynasty Daye iron ore stable excavation of 60 meters deep holes, and now the popularization of iron and steel to easily excavate 100 meters of various mineral deposits, but aspiring craftsmen are not willing to be satisfied, they think that the current technology can be fully exploited 200 meters, 300 meters or even deeper underground deposits.

For this dream, Wei Changjun gave up the privileged life in Chang'an City, gave up the high-paying and easy mineral research work provided by Shaofu, and came to the humid and hot mountains of Yuzhang County in the south, and stayed for four whole years without going home.

It's not good to not see your wife and children for four years. His eldest son, Wei Yannian, is seven years old this year, and his second daughter is five years old this year. After not seeing the child for four years, I can't remember what the children looked like back then, especially the youngest daughter who left home when she was just over a year old. Four years of not going home has accumulated too many hometown wishes.

Staring at the scribbled handwriting on the scroll, Wei Changjun closed his eyes and silently wandered, more than 30 people in the staff group held the hill and studied the scroll for more than a month, and the mining plan was no less than five hundred, and most of them were refuted, and there were still more than a dozen of them through the demonstration link, entering the most difficult and dangerous actual mining experiment, and the effect could not be seen which one was superior for the time being, and the best underground mining plan was still not set.

Wei Changjun said: "Our progress must be accelerated, and the open-pit copper mine will be hollowed out sooner or later. If we irresponsibly push away the argument and then there is a cave collapse that kills people, or the ore collapses to block the exit of the mine, and hundreds of miners are blocked in the hole, it will have a very bad impact. ”

The staff looked at each other and said, "We can't find a better way to prove which is better for the time being, and the best way for now is to use a support frame against the mine to protect the safety." ”

"More than a dozen schemes in the experiment have support frames, but which support frame should we choose best?"

"You should choose the pure steel from Binh Duong Forging and Metallurgy, which pure steel is of excellent quality. Strength and toughness are the only good materials that can be seen in life, and there will be no problems when made into a support frame for at least a few decades. ”

Wei Changjun shook his head: "No, the nobles use it to make swords, and the army uses it to make weapons." Ordinary people used it to make agricultural tools, craftsmen used it to make tools, and every industry needed pure steel. It's just that the manufacturing cost of pure steel is high, the output is low, and the market demand is large. The resulting price is amazingly expensive, not to mention the use of a huge support frame. Even a set of pure steel for armor and shields is hard to find, and we can't afford to use it. ”

"Then use pig iron."

"Pig iron is too brittle."

"Where's wrought iron?"

"Too soft."

The craftsmen were anxious: "I heard that Pingyang Houfu announced a simple steel filling method, although it can't make good pure steel, but a little less crude steel can also be tried to make, it is better for us to purchase pig iron, wrought iron to make crude steel by ourselves, maybe we can also produce pure steel in the future." ”

"That's not appropriate, is it?"

"We're not suitable? How many people are producing crude steel, but Shaofu strictly does not allow small workshops to produce, and if they are caught in illegal production, they will be punished and confiscated and exiled to the border county Wancheng Danqing, our Shaofu bureaucratic qualifications are absolutely passable, and the production of steel is not for their own selfishness, just write a letter and send it to Shaofu to explain. ”

Wei Changjun thought about it, there is indeed no better way, it is very unsafe to use pig iron as a support frame, and the cost of purchasing steel is expensive and frightens people to death, so he has to purchase his own production after thinking about it.

At this moment, a voice sounded outside the tent.

"Wei Lingcheng is overjoyed!"

Raising his eyes, he saw the messenger of Shaofu walking in: "Congratulations to Wei Lingcheng, the third sister of your family, Wei Meimei, gave birth to a little princess for the Son of Heaven, the Son of Heaven is overjoyed, and Wei Meimei is promoted to be his wife, and Wei Lingcheng will be blessed soon!" ”

Wei Changjun was startled at first, and only after asking the ins and outs did he paced around happily.

He didn't know his sister's situation, he went to Yuzhang County to mine copper ore relatively early, but he vaguely remembered that he seemed to be liked by the Son of Heaven for the third sister Wei Zifu, and he didn't know much about the specific situation, and even the news that Wei Zifu entered the palace as a beauty was also known from the family letter, so he didn't think about it in his heart at all.

"Great, everyone has worked hard, I'll invite you to dinner tonight."

"Okay!"

Thousands of miles away, Chang'an City is too learning.

Sang Hongyang studied in law school, and the young man who was about to turn seventeen served the Son of Heaven for nearly five years, and he was exposed to knowledge in the court that ordinary people would never have access to, which also made him realize his shortcomings and gaps.

His background is a wealthy Luoyang wealthy merchant family, the youngest son of the eldest in the family is very favored, but in the Han law is a child who has no inheritance rights, whether it is the title of the family or the land has nothing to do with him, at the age of twelve through a special selection to be sent to the court as a servant, and then turned into a Lang official to serve the emperor conscientiously, and finally entered the Taizhong doctor only to find that his knowledge is seriously insufficient.

The businessman is in contact with calculations, mental arithmetic, dealing with the ledger and the merchants who come and go every day, he has an excellent mental arithmetic skills, but that is only for the business service of the livelihood skills, Sang Hongyang's real shortcoming is that the understanding of the classic books is very little, the early days of the rough text have also read the "Lao Tzu" five thousand words and "poems", "Spring and Autumn" two Confucian classics, the impression is just a difficult words piled up of esoteric knowledge, just like the book of heaven is difficult to understand.

Knowing that you entered the central system of the Han Dynasty, you found that if you don't understand the "Book of Law", "Han Feizi", "Shang Junshu", and don't understand "Guanzi" and "Monetary Theory", it is difficult to communicate with professionals.

Forced to finally think of further study, he can only come to further study and recharge for better opportunities.

"The ancient word for the law is 灋, from the water, from the 廌 to go, 廌 that is, the pig also! This is actually a kind of divine beast, this divine beast can go to the person who is not straight, the ancient sages often use this beast to judge the prison of difficulty by the water, Li Kui in the pre-Qin era has made thousands of words in the "Book of Law", I believe you have also read it, the word law is used to represent the legitimacy of the execution of the punishment judgment, his disciples are called legalists, Shang Yang changed the law to the law, the meaning of the word law is very different, the law usually refers to the major policies of the military state, so the law is changeable, the law is immutable. ”

On the podium, a young lecturer of law is speaking at length.

Sang Hongyang frowned when he heard this, probably figuring out the meaning of what he was going to say, this young lecturer was the avant-garde of Huang Laoxinxue, and the core content of what he said was that the evil law was illegal, mainly expounding the concept of good law and bad law, and the officials who exercised the law must conform to the interests of the majority of the people, maintain the stability of the court and the fairness and justice that the people need, not to destroy the purity of the Han law for themselves.

"You should pay attention to the incident that happened in Hedong County, Governor Zhou Yang wantonly cultivated party henchmen for his own selfishness, the loved one can bend the law to live, and the hateful person can bend the law to destroy it if he is not guilty, and he fought with Hedong Taishou Shen Tu Gong for several years, collected evidence and framed him to do everything, and once succeeded in confusing Tingwei to take down Taishou Shen Tu Gong, until he was exposed to the bottom to save the crisis, this incident proves that there are still selfish desires in our honest bureaucratic system, tampering with the law and violating the Han law, the Son of Heaven ordered to be guilty of great rebellion, Che Crack Zhou Yang set an example, which strongly proved that the Son of Heaven was sage, and most of the bureaucrats in the court were honest and honest. ”

The sound of the horse's ass slapping caused the students below to cover their mouths and snicker.

Sang Hongyang pondered for a long time and recalled, Huang Laoxinxue put forward such a point of view should be to compete for the right to academic discourse, the definition of good law and bad law was originally vague, and it was not feasible to say deeply, whimsical laws were also bad laws, and laws that did not meet the needs of the contemporary people in backward times were also bad laws, and good laws must be constantly changed, added and deleted new content to maintain vitality.

"It is necessary to avoid evil laws and laws, thinking that evil laws and laws mean that the bureaucrats in the world will pay the price for the selfishness of some officials who are greedy for selfish desires, unqualified bureaucrats must be resolutely eliminated, outdated laws must be resolutely abolished, and it is very stupid to blindly safeguard the honor and interests of the bureaucratic collective, because your behavior is gambling with the credibility and prestige of the imperial court, and the consequences of gambling will inevitably lead to the collapse of the reputation of the imperial court, the fierce resistance of the people, and the fall of the tyrannical Qin is a good example."

Listening to it, it was about part of the content of "On the Death of Qin", and the students of the law school did not feel that the lecturer was carrying private goods at all, but listened to it with relish and applauded from time to time.

Sang Hongyang once listened to Cao Shi's explanation of "The Death of Qin", and he still remembers the general content very clearly, this time he expounded the process of the fall of the violent Qin from the perspective of dishonesty and dishonesty of the people, and explained the reason why more than three million people of the late Qin in Guanzhong were indifferent to the fall of the violent Qin.

After listening to a class, Sang Hongyang picked up the package and prepared to listen to the next class.

Inadvertently walked to an empty teacher, the deputy priest Jiu Zhi did not doubt supervise the ten-year-old boy to write articles, Zhi Bu did not hesitate to make a silent gesture at him, he was very curious to walk over and saw a stack of books with the words "Sima Qian" written on it.

"Sima Qian? Very interesting kids. (To be continued, please search, the novel is better and faster!)

ps: Sorry for being late, I'll find a way to make it up tomorrow
