Sun Ce and Huang Chengyan entered the house, but Huang Yueying didn't know where to hide and disappeared. Sun Ce knew that the little girl's face couldn't be wiped off, and he didn't look for her. The two sat on the side of the desk, and Sun Ce said that Chang'an might have changed, and he was going to Ruyang for a funeral, and he was going to avoid the limelight for the time being, and finally explained the reason for revising his merit book.

Huang Chengyan listened quietly and did not make any suggestions until Sun Ce finished speaking, and he nodded.

"It's really embarrassing that the general has been able to make such progress in a few months."

"So, the father-in-law doesn't object?"

Huang Chengyan glanced at Sun Ce, and stopped talking. The word zhangren refers to both the elderly and the father-in-law. He has just reached middle age, although he is older than Sun Ce, but he has not yet reached the status of being called a father-in-law. Sun Ce called him his father-in-law, which meant to agree on the marriage contract. Although this is not polite, it shows that Sun Ce is sincere.

"I'm just such a daughter, what's there to object to. It's good if Achu likes it. ”

Sun Ce nodded. "When my husband says so, I don't have any worries. I estimate that there may still be a war in Nanyang, and the iron officer must hurry up and complete the change of equipment of the whole army as soon as possible. What have you learned lately? ”

"Not yet."

"You can compare the methods of iron smelting from ancient times to the present. The most important thing is whether the impurities in the pig iron can be removed and made into pure iron. The fewer impurities, the purer the iron and the better the toughness; One is to add the required ingredients and turn iron into steel, different components have different effects; One is quenching to make it sharp, and the temperature and the speed of cooling down are the key. ”

Huang Chengyan was stunned. Twisting his beard, squinting his eyes, he looked at Sun Ce. He has been studying the records of the iron official these days, and he has some experience, but there is still a long way to go before he really understands the secret. Sun Ce had never been a blacksmith for a day, but he suddenly said three important steps to make iron tools, which was really incredible. He hadn't verified it yet, but he had an intuition that the three points Sun Ce said should be the biggest reliance he had always relied on for daring to hand over the ordnance manufacturing to the Cai family. Sun Ce didn't say it, even if the Cai family tossed for another ten years, they might not be able to understand the truth.

Now, he has handed over these reliance to him, Huang Chengyan.

"Iron smelting is a very deep knowledge, and it can even be called the lifeblood of a country, which is worthy of a lifetime of study. Nanyang has been the place of the iron official since ancient times, and it is also the place of the four wars, there is a huge demand for high-quality weapons, and any breakthrough may quickly turn into an advantage, such convenient conditions are not available everywhere. ”

Huang Chengyan is a smart person, and he immediately heard the promise behind Sun Ce's words. Mastering the advanced iron-smelting technology, not only will the Huang family get rich returns economically, but also unimaginable support in the military circles. What general doesn't want to get the best weapon? As long as Sun Ce does not object, the Huang family can call for wind and rain under his rule, and no one dares to bully.

What about the Yuan family? The Yuan family was just a promise from Sun Ce to Yuan Shu.

"I'll arrange for someone to try it right away."

"Don't worry." Sun Ce raised his hand and pressed Huang Chengyan's arm. Huang Chengyan immediately sat down. Sun Ce said: "To do technical research, you can't rely on the wisdom of just one person, you need to gather the wisdom of many people. By leaving those specific tasks to others, you will be able to take charge of the overall situation and delve into the Tao inside. There is no way to talk about it, daydreaming, there is no way to do it is a plate of loose sand after all, and it is impossible to build a high-rise building. ”

Huang Chengyan raised his eyebrows, understanding what Sun Ce meant. He is different from ordinary scholars, he attaches great importance to the practical learning of wood and machinery, but he is alone, and he basically still spins around within the scope of art, and does not rise to the Tao. In the past, the conditions were not available, but now that the conditions are, it would be a waste if he still did this. With the Wood School in hand, he can leave the art to the students to do, control the overall situation by himself, and focus on the Tao.

Paying equal attention to iron and salt is a major event related to the rise and fall of the country, who dares to say that this is a small technique?

There is no scholar who does not want to start a sect, but he just talks a lot and can really do little. Huang Chengyan is no exception. Now that the time, place, and people are all available, if he can't make some achievements, he will be sorry for himself.

Huang Chengyan twisted his beard and sighed softly: "Zi said: Those who are born to know are also above." Bo Fu, you have extraordinary qualifications, don't waste it. ”

Sun Ce's eyes flashed and he smiled. Huang Chengyan is a human spirit, he is obviously suspicious of the source of his knowledge, but he does not ask directly, and provides him with a wonderful excuse. The saint was born to know that this was indeed a good excuse to explain his knowledge of unknown origin, and it could build momentum. There are saints in 500 years, which is an inherent concept that Confucianism is deeply rooted in the hearts of the people, and it has a market just like the five virtues have always said. There are many self-proclaimed saints, but there are only a handful of people like him who have the condition of "being born to know". After all, he is the closest to a saint.

I won't explain this for the time being, otherwise Huang Chengyan will go crazy nine times out of ten.

Sun Ce and Huang Chengyan talked for a long time, but Huang Yueying never showed up. Sun Ce didn't force her, and left the backyard with Huang Chengyan and came to the front yard of the Wood School to watch the craftsmen make models. There are more than a dozen craftsmen in the model room, which can be regarded as the elite of the wood school. There were a lot of patterns on the shelves around them, and the freshly painted walls were blackened by oil lamps. It can be seen that in order to study the four-wheeled vehicle, the craftsmen of the Wood School have spent a lot of effort.

You don't need to be proficient in wood science to know that the advantages of four-wheeled vehicles are obvious, large load capacity, easy to balance, as long as you build it, it can come in handy immediately, and you don't have to worry about sales at all. When the time comes, Mu Xuetang can get a generous stipend again. In order to motivate the teachers and students of the Wood School, Sun Ce stipulated that whenever there are new achievements, if they can immediately produce economic benefits, then transfer these technologies, whether they are transferred to the baggage camp or to private individuals, and the Wood School can obtain a certain amount of technology transfer fees. If it cannot produce economic benefits for the time being, it will be taken over by the baggage battalion as a technical reserve.

At present, Mu Xuetang has two largest incomes: one is the technology transfer fee of the stone throwing machine, which is a one-time transfer, the amount is as high as 100 gold, Sun Ce was poor at the time and couldn't afford to pay, so he paid with the loot in kind. The second is that the Cai family's new weapon technology transfer fee is paid in the form of shares, although the amount is not large, but it is available every month, about ten gold. With these two incomes, the Wood Academy now has sufficient financial reserves, and even the most ordinary apprentices can maintain a basic life.

In a word: not bad money.

With institutional guarantees, there is no need for anyone to mobilize, and the enthusiasm of the carpenters is very high, and there is an endless stream of people who sign up for the study.

At this moment, the craftsmen led by Mo Ze were very devoted, and more than a dozen people were huddled together, discussing how to refine Huang Yueying's design. Huang Yueying just put forward an idea, and there is still a lot of work to be done to turn the idea into a practical and feasible plan.

Sun Ce didn't bother them, and agreed with Huang Chengyan to go to worship Zhang Heng together, and quietly left the Mu Academy.
