When the cold wind blew from the north, the temperature plummeted, and even the big river began to freeze, Zhao Yu's blast furnace finally became it.

The blast furnace stands next to the waterwheel at the drop of the canal in the backyard, and a blower is connected to the waterwheel. This blast furnace is not big, no more than two zhang high, and it is all forged by Zhao Yu with mana and runes inside and out, and it is all one.

Two thousand years later, the steelmaking blast furnace of modern time and space must have refractory bricks inside, but Zhao Yu did not.

It is the miraculous power of the talisman that replaces many necessary structures, making this blast furnace very strange.

Not only do you not need refractory bricks, but you don't need coke.

And it's extremely efficient.

According to Zhao Yu's estimates, this blast furnace, as long as the raw materials are sufficient, can produce high hardness, high toughness, high wear resistance and corrosion resistant steel every day, with a minimum of five tons and a maximum of more than ten tons.

In fact, the steel formula that Zhao Yu has studied is probably not quite the same as all kinds of steel in modern time and space. It seems to be the product of a fusion of the advantages of many different steels. Practicality is extremely high.

Of course, it's nothing. After all, he Zhao Yu is a monk, and now he has mana, if there are materials, even magic weapons can be refined, let alone this kind of mundane steel. His formula is based on the knowledge of modern time and space-related books, combined with some means of refining, and delved into a steel formula suitable for mortals.

In the Tianyan Mirror Illusion, although many of them are false existences, there are also many true truths. Fiction and reality, removing the false and keeping the true, Zhao Yu has now gradually completed this process in various experiments.

The refining method in the illusion realm is useful, and he has refined a lot.

At the same time, there is also the art of talismans.

At present, this blast furnace can probably be called the mother furnace. When Zhao Yu was making this blast furnace, he racked his brains and decomposed the immortal means contained in the forging method of this blast furnace one by one, and obtained the manufacturing process suitable for mortals.

In other words, with the process he decomposed, as long as there are enough materials, ordinary craftsmen can build a blast furnace with the same function, which may be much less efficient, but can smelt the same quality of steel.

Zhao Yu's purpose was not to build a magic blast furnace. Ritual weapons are only suitable for monks. Unless there are many people in every generation of this world who can become monks, otherwise, the method of refining magic weapons will be out of print. When he leaves, he will be deserted. But it's almost impossible. There are very few rooted beings, which is outrageous.

His purpose was to decompose the means that were close to immortal paths and make them applicable to mortals. In this way, the effect of long-term and drastic impact on time and space can be achieved.

The blast furnace manufacturing process decomposed by Zhao Yu and the blast furnace manufactured by Zhao Yu are definitely different from the mother furnace. Because you won't use the art of talismans. Therefore, there are other means of substitution such as refractory bricks. In order to achieve the efficiency of this mother furnace, the volume of the blast furnace manufactured by ordinary processes must be increased by at least five times.

In all respects, although somewhat degraded, it is good enough.

Zhao Yuzhi looked at the blast furnace proudly and asked Wang Tiandao: "How much iron ore, limestone and charcoal are stored?"

Coal is coal. As early as the Western Han Dynasty, the Zhuxia people began to exploit and utilize coal on a large scale. So it's not strange to think of such a thing as carbon. Wei Zhen's trading house, during this period of time, has continuously transported the materials on the silk cloth that Zhao Yu gave Wei Zhen at the beginning, which made Wang Tian have to build a large warehouse to store it.

"A lot. Wang Tian said: "In the past month or so, the number of various materials delivered by Weijia Commercial Bank has increased significantly. The previous warehouse is almost out of storage. The iron ore has exceeded 300,000 catties, and the charcoal is not much worse..."

"300,000 catties... Inadequate. Zhao Yu thought intently and said, "Let Wei Zhen increase large-scale mining." Anyway, glass and soap come in a lot, and it's useless to put money there, and it's only useful to use it. ”

300,000 catties of iron ore, calculated as only 300 tons, is too little. Even if it is a rich mine, a few hundred tons of iron ore will not make much steel. Only this mother furnace can be quickly digested, and once more blast furnaces are built in the future, not to mention hundreds of thousands of catties, even if it is hundreds of millions of billions, it is not enough to consume.

"Wow. ”

Wang Tian immediately responded and kept it in his heart.

"Craftsmen should be grouped. Zhao Yu's words were very jumpy, but Wang Tian was used to it.

Zhao Yu said: "Over there in the cement kiln, just leave a few skilled craftsmen to guide." Count as a group. A group of water wheels, so that they don't stick to my finished product, if they can develop more new features, there are rewards. It is enough to keep ten people in the waterwheel group, and the rest are divided into the steel group. In the next few days, I will teach them the process and method of making this steelmaking blast furnace..."

When Wang Tian heard this, his face showed a worried expression: "Owner, I don't know what the big truth is, but steel is precious, and the smelting method is too important, so it can't be easily taught to others." ”

Zhao Yu smiled and waved his hand: "It's okay." I believe in them. ”

Zhao Yu didn't believe in them, but in himself. He doesn't believe it, who dares to mess around. Otherwise, the world is so big that there is no place for him.

Annoying Zhao Yu is even more terrifying than provoking Cao Mengde.

"You usually pay more attention to it, if you really have something else in mind, just find out early. ”

"Wow. ”

Seeing that Zhao Yu had made up his mind, Wang Tian didn't say anything more.

"By the way, have the potatoes been harvested?"

Zhao Yu asked suddenly.

"Collect!" Speaking of this, Wang Tian's eyebrows immediately fluttered: "Boss, don't you know! The yield of potatoes frightened people! At that time, many farmers were dizzy..."

Zhao Yu thought about it in his mind, and it seemed to be true. However, at that time, he was immersed in blast furnace manufacturing, and it seemed that Wang Tian had come to report.

"How much?"

"The yield per mu is more than 200 stones!" Wang Tian took a deep breath, although it had been several days, but when he talked about it, the shock could not be concealed: "Two hundred stones, the owner! If potatoes can be popularized, there will be countless living people!"

One stone is one hundred and twenty catties, and two hundred stones are twenty-four thousand catties, but it was not beyond Zhao Yu's expectations. But in this era, it can shake people up. Even if it is a good year, the wind and rain are smooth, and the grain yield per mu is only two or three stones, two hundred stones, that is a hundred times!

Zhao Yu nodded lightly: "Okay." Don't eat these potatoes if you can, keep them. Seed at the beginning of the year, plant it... By the way, how much land has been encircled?"

There are many things that Zhao Yu ignores because he is immersed in the process of manufacturing blast furnaces, and he doesn't even know it.

"Lao Zhang has circled more than 30,000 acres of land. Among them, there are only thousands of acres that were bought with money, and the rest are ownerless wasteland. Before the beginning of the year, more than 50,000 acres of land will not be a problem. ”

"Good. Zhao Yu nodded: "Before sowing seeds at the beginning of the year, remember to do a good job in land distribution." ”

Zhao Yu paused: "I don't care about a lot of things in Zhuangzi. You and Zhang Wang must do our best, and we can't be sloppy, otherwise..."

Zhao Yu said lightly, but when Wang Tian heard it, his expression immediately straightened up, and he said, "The owner, you are serious. Zhang Wang and I were desperate people, but thanks to the favor of the Dong family, we are where we are today. If you don't do your best, heaven and man will kill together!"

Zhao Yu bowed: "That's good." ”

The super harvest of potatoes really made the people in the whole Zhuangzi happy until the beginning of the year.

The joy that comes from the heart of people doesn't need words to describe it.

In such an era, when war is raging, having such a high-yield grain is vital to the lives of any people in the world.

Although Zhao Yu does not appear often, in the minds of the people of Zhuangzhong, he has long been a god who saves the suffering.

The end of the year has arrived, and during this time, Zhao Yu has more free time at hand in addition to instructing craftsmen in the method of manufacturing blast furnaces and the process of smelting steel. During this period, the guards of Zhaojiazhuang led by Dian Wei also obtained a technique passed down by Zhao Yu.

Before coming to this time and space, Zhao Yu created several exercises in order to practice. And what was taught to them was a thick earth skill in the Five Elements Quan Sutra.

And Dian Wei is different after all, Zhao Yu passed on the Five Elements Fist Sutra to him.

After a few days of guidance, he let it go and left it all to Dian Wei to deal with. Dian Wei has something he doesn't understand, so let's ask him again.

In this era, the Spring Festival has not yet become the biggest festival.

The first festival after the beginning of the year is the Shangyuan Festival, which is the fifteenth day of the first month.

On this day, Zhao Yu made a rare appearance and had a happy day with the people in the village.

And at the suggestion of Baili Shi and others, he presided over the sacrificial activity on this day.

Baili Shi is in charge of the natural residence, and in the past six months, the business of the natural residence has become more and more popular, and the output of the village has become more and more abundant, and he has begun to open branches in the surrounding counties. Of course, this matter was Zhao Yu's suggestion. Pingsu Baili Shi rarely returns to the village, but when the festival is over, he must come back.

The sacrificial activities of the Zhuxia people are very solemn. It expresses the awe of the Zhuxia people for the nature of heaven and earth. That is, in this year, the Han Dynasty fell, otherwise every spring, the Son of Heaven would preside over the sacrifice. Sacrifice to the god of spring, sacrifice to Hebo, sacrifice to the rain master and so on. These gods are the embodiment of nature. In the sacrifice, there is the ardent expectation of the Zhuxia people for the new year.

There are big sacrifices in the country, and there are also sacrifices in the folk villages. The three elders who are highly respected in the township, an important responsibility, are here. Sacrificing ancestors and sacrificing gods is to appease people's hearts.

The so-called national events are in worship and worship.

Zhao Yu is not disdainful of this. Zhao Yu believes that sacrificing to the gods of nature and sacrificing ancestors is an indispensable part of humanity because of the reverence for the nature of heaven and earth and the nostalgia for the ancestors. On the contrary, in the era of 2,000 years, people think that they have mastered everything, and they no longer have reverence.

Let's not talk about the sacrifice, the specific steps, an old man came to tell Zhao Yu. Zhao Yu followed them one by one.

After the festival, it's busy again.

Especially after the Qingming Festival, farming has entered a busy stage. Before and after the Qingming Festival, melons and beans were planted.

In the era of war, people will deeply understand the difficulty of peace. So, busy and busy, but happy in the heart.

And Zhao Yu is becoming more and more leisurely.

It's not that he doesn't have more things to do, he still has a lot of ideas, but it's not time to start doing it.

On this day, in the study room in Zhuangzi, Cao Chun and Xiahoudun were sitting opposite Zhao Yu.
