With coal, Wu Zheng's first thought was to burn the stove, but when he thought about it, there was no shortage of firewood or charcoal in Yuzhou, and even if the coal stove was made, who would it sell it to?

Instead of casting pig iron furnaces, it is better to use pig iron to make steel, yes, steelmaking is a good thing, I heard that Qi Wuhuaiwen in the Northern and Southern Dynasties has improved the steel filling method quite well, and there is no shortage of iron ore in this place in Yuzhou, although iron and salt are monopolized by the government in this time and space, but it is not impossible to buy it, otherwise where is the blacksmith shop?

At that time, as long as the pig iron and wrought iron are bought back, and they are turned into steel by the steel filling method, there will definitely be a profit, as for how much profit can be asked, ask Uncle Yang, the blacksmith in the village, he is an old expert in this area.

Of course, making money is secondary, after all, this thing is as difficult to sell as salt, but making a steel donkey is Wu Zheng's dream since he came to this world.

In addition, now Wu Zheng knows that the world is not as peaceful as he thought, especially after experiencing the rebellion of the Red Lotus Sect, the idea of training an armed force based on long-range strikes to protect himself has become even more urgent to distribute a steel sword that is no less powerful than the Divine Arm and is not limited by the weather.

Just do it when you think about it, anyway, it's okay this winter, you have to find something to do, you can't just waste the years.

So the three of them sat on the kang and chatted, and sure enough, the method of filling steel was lost, or it was unknown which book it was lying in, after all, there was no dynasty in this feudal era that could afford to look at craftsmen, and many treasures left by the ancestors were shelved because of a such as a strange trick.

Sometimes Wu Zheng really wants to know who his mother said this sentence, if he lets himself bump into him, he must be scraped with a thousand knives, if there is no appearance of this sentence, maybe I will not have such a shame as the whip.

Now that I have come to this era, as a talented, characterful, economic, and responsible New Year, it is my duty to let the rise of China take place.

Besides, the wheel of history has already made Wu Sansi's little stone seed turn into the ditch, so why can't I let this stone seed roll a little farther, and it's better to turn into the sea? In the future, even if it has any self-correction, it can only sigh.

After learning from Uncle Yang's mouth that there is indeed no steel filling method in this world, Wu Zheng planned to do it himself.

Although Wu Zheng is almost about to become a god in the stockade now, Yang Er is still skeptical about the fact that wrought iron and pig iron can be turned into steel by burning them together.

There's no way not to doubt it! Because if it can be made into steel so easily, then isn't it a joke that the most bullish steel is now being made into steel?

You must know that this method is Yang Er's secret that cannot be passed on, and this is a family heirloom that can only be passed on to his children and grandchildren after his death.

And the people who can master this craft in the whole Great Zhou can not say that they can count it with one hand, but they can definitely count it with one hand.

As a result, Wu Zheng smiled and said: "What's the secret, isn't it just that fried steel is used as raw material, which is repeatedly heated, folded, and forged into better quality steel?" ”

Yang Er, who was smug when he heard this, was stunned at that time, and pointed at Wu Zheng for a long time before saying, "This ...... Do you know this uncle? ”

Wu Zheng patted Yang Er's hand and said with a smile: "Uncle Yang, our family doesn't speak two words, if you really want to pass on a stunt to your children and grandchildren, and make your old Yang family the originator of Mount Tai in the smelting world, this steel-filling method of the kid will definitely be ten million times stronger than your hundred steel." ”

As for how many times stronger, Wu Zheng doesn't know, but does it matter? Anyway, they are inciting people's hearts, and if they don't blow the benefits to the big inside, how can this stir up people's hearts, if they are not encouraged by themselves, how can they use their lives to make steel?

"Uncle, don't trick me, is there anything better in this world than a hundred steels?"

Wu Zheng smiled: "Uncle Yang, don't you believe it? How about we make a bet? ”

"Bet? I don't dare to bet with you, uncle, that you are now the gambling god in the eyes of those boys in the village. However, this method of filling steel can really be as magical as what you said, so what does it matter if my Yang family has served my uncle for generations? ”

"There's no need for Uncle Yang to swear such a poisonous oath! All at once put the children and grandchildren into it. ”

Yang Er said disapprerovitously: "What I want, if my Yang family can really become the ancestor of Mount Tai admired by future generations in the smelting world, what a glory this must be, if such glory is taken for nothing, it will be bad for God, rather than children and grandchildren will be cut off by God's curse, it is better to sell themselves as slaves but enjoy the glory of the world forever." ”

There are no fools in this world, this Yang Er seems to be honest and loyal, but just now he took away this method of filling steel with this sentence, which means that if this method of filling steel is really done, then it will be his Yang family in the future.

In order to repay him, the Yang family is willing to be a slave for generations, but what do I want you to do as a slave? You must know that the slaves of this era already have human rights, and if the master kills a maid, although it will not be fatal, it will also be punished with copper.

Besides, can this slavery really be for generations? That's not necessarily, at least Wu Zheng knew that in his time, if anyone dared to let someone sentence you to be a slave for ten or eight years, it would be light, even if it was a servant, there were still people doing it, but was that called a slave? Is that called housekeeping? This salary can envy a large number of white-collar workers.

And if you have the heart to turn the wheel of history upside down, that era may come early.

Of course, these are a bit far-fetched, and even if you are willing to be a slave and a servant, but you have such a ability, do I dare to treat you as a slave?

So Wu Zheng couldn't help shouting in his heart at this time: "What do I want you to do as a slave and a servant, what I want is money and silver, can you always give me something practical, don't play these fictitious things, okay?" ”

Yang Er continued: "I don't know what kind of furnace my uncle needs for this method of filling steel?" ”

Wu Zheng glanced at the old man, as long as he thought that this old man was going to take his own method of filling steel for nothing, how did he think that this old man was unpleasant now, and he immediately asked for the stove without believing it just now.

So now even if Wu Zheng knows about the earthen stove used for filling steel, he doesn't plan to say it explicitly, but only says: "I don't know about this, it's convenient for you to be an expert!" Anyway, as long as the pig iron can be melted just right, and then the molten iron is poured over the red-hot wrought iron. ”

"This ...... Okay, old man, I'll go back and think about it. But uncle, we have some pig iron in our village, but there are not many wrought iron. ”

"Uncle Yang, I didn't say that I want you to refine a few hundred catties at a time, although I know this method of filling steel, but after all, I haven't done it myself.

So this is the early stage! You still have to find out by yourself, Uncle Yang, to sum up your experience.

As long as the fist size is enough, it is best to make them all into iron blocks of equal weight, so that you can save the time of filling steel each time, and it is convenient for you to sum up your experience, right? ”

"Uncle spoke, sure enough, every word was full of wisdom, just by virtue of this sentence, the little old man now believes in this method of filling steel. Please rest assured that even if the little old man fights for this old life now, he must refine this steel for his uncle. ”
