Although the blacksmith shop is already under construction, it is too early to be completely completed - and in Gao Wen's plan, this wooden house is actually not the same as the "blacksmith shop" that people in the world recognize. However, in order to facilitate everyone's understanding, he temporarily called this place a blacksmith shop.

According to his meaning, he planned to name this place "Cecil Steel Factory"...

As the only blacksmith in the territory, the old man Moer was also quite confused by the "blacksmith shop" ordered by the Duke. In his opinion, this building really occupies an unnecessary huge area. In addition to a surprisingly large board house, it also includes an open space of 100 meters long and a wooden shed with only a few brackets currently. It would be inappropriate to call such a large facility a "blacksmith shop", but he did not dare to say that the famous founding grand duke was an outsider who did not know how to pretend to be a blind command - although he did think so in his heart, he absolutely did not dare to say it.

After all, he was just a civilian, and the other party was a great nobleman who could be on par with His Majesty the King.

Due to the amazing area of ​​this "blacksmith shop", it can only be placed on the eastern edge of the camp. Its "big yard" extends to the wasteland outside, as funny as a neat wooden fence. The guys brought from Tanzan Town seem to be a little pitiful in this giant blacksmith shop: they only occupy a corner of the wooden house, and the only iron smelting furnace was placed outside on the open space, blocking it with a simple wooden shed to prevent wind and rain.

For Gao Wen, he arranged the reserved land of the blacksmith shop so large, and was close to the edge of the territory, but only took into account future production capacity requirements and convenience of expansion - in the traditional era, a master brought several apprentices, a small house brought a furnace, and a blacksmith shop that hit iron tools was not what he needed at all.

But he had no way to explain all this to the old blacksmith and his stupid apprentices now.

In addition to the considerations of production capacity and future expansion, Gao Wen did not intend to directly erect a bunch of earth blast furnaces in this yard like the time traveler predecessors in the novels he had read. Although he did think so, after seeing Hetty use magic power to help the raft dock and help the camp strengthen the foundation a few days ago, he temporarily suppressed this idea and instead let Hammer, the only blacksmith in the territory, build a traditional furnace in the yard.

He came to the blacksmith shop, where Rebecca was already waiting, and the old blacksmith Hammer, with gray-haired bearded, and several of his apprentices, and several other leaders in short shirts stood in the yard, and the first batch of ores were transported in the big basket under their feet.

Gao Wen walked straight to the traditional furnace.

It was a furnace that looked quite rough, about one meter high, divided into two parts, above and below. Below is an enlarged hemispherical structure, which quickly shrinks into a cylinder. On the lower hemispherical structure, you can also see two openings, one is located below, which is obviously the place where fuel is added, and the other is located close to the cylindrical structure, where ore should be poured.

These parts are nothing special, they are just ordinary furnaces, but their special parts are on the side.

There are three runes arranged there.

All three runes are carved on a kind of black stone flake, and the three stone flakes have obviously been carefully polished and carefully adjusted before being embedded on the furnace body to ensure that they are completely consistent in spacing and parallel in the edges. The bottom stone flake is engraved with a triangle symbol, and there is a wavy line inside the symbol, which is the starting character representing the fire element in the magic book; the middle stone flake is a square with a diamond, which is the starting character of the earth element; the upper stone flake is a swirl-shaped symbol, which is related to the wind element, but is not the starting character.

In addition to these three stone flakes, you can also see some subtle and shining dust in the material that builds the furnace body. Gao Wen knows what it is: quartz sand, quartz sand of "this world".

Quartz sand is a material with magical properties. Although its effect is extremely weak, it is widely used because it is cheap enough to be used by ordinary people.

Gao Wen raised his head and glanced at the old blacksmith: "Did you make this stove?"

"Yes, yes, yes..." When the old blacksmith heard the lord ask him, he immediately grabbed the hat in his hand nervously, and hurriedly lowered his head and replied, "Oh, half of it was made by me, and half of it was made by me instructing the apprentices..."

Gao Wen nodded, but there were no more problems.

Magic is an extraordinary force and is not a field that "untouchables" can reach. However, in this world full of magic power, even civilians who cannot cast spells actually have a shadow of magic in their lives.

Some basic applications of magic do not require mastering the knowledge and ability of casting - everyone has magic power in their bodies, and as long as they use a specific material and write a simple symbol on a specific shape of materials, everyone can slightly induce those ubiquitous wonderful powers.

This is not a spell cast at all. The effect is almost ridiculous to those real "extraordinary people". This kind of leverage is like picking up a stick on the ground as a crutch, picking up a stone everywhere to smash walnuts. Even illiterate civilians can remember how to draw a few symbols with weak effects. But it is this little bit of power that determines that this world is completely different from the hometown that Gao Wen is familiar with.

It's like the degree of Celsius when the water boils.

With those three runes, this "traditional furnace" only needs to use firewood as fuel, and can produce molten iron without using a blower and without optimizing the combustion chamber structure.

If the runes of the fire element are engraved on a piece of mites silver, this stove can even use straw as fuel!

However, it is precisely because of the existence of these ancient runes that humans in this world have not yet considered how to improve the efficiency of the furnace from the perspective of improving fuel combustion efficiency - what they are constantly improving is only the materials used to carve runes and the format of the runes themselves.

So Gao Wen did not build any earth blast furnace, but first observed this primitive and backward traditional furnace.

The old blacksmith Hanmer looked at the great nobleman in front of him with more and more nervousness. He didn't know that the other party suddenly asked a question and then studied what the furnace was intended, nor did he know if he had done something wrong. He only knew that the nobleman was powerful and uneasy. Although the lord Miss Rebecca and the lord earlier were both kind and generous, the person in front of him was the legendary pioneering hero, a thorough warrior, and a duke. What would the character of such a great nobleman be like?

Just when the old blacksmith was worried, Gao Wen finally stood up and asked him the second question: "How much iron can you make every day with such a stove, while ensuring sufficient ore supply?"

Hammer suddenly breathed a sigh of relief: Finally, he asked a normal question.

"If you use the ore there, you can make fifty kilograms of iron every day." The old blacksmith said proudly.

However, when Gao Wen heard this answer, he couldn't help but frown: "So little?"

With those rune aids, is there so much output?

"Is this too little?" Hammer couldn't help but say, and then he nervously remedyed it. "I'm not questioning your judgment, but..."

"It's okay, don't be nervous when talking to me," Gao Wen comforted the master, "I am the lord who protects you, not the robber who is here to kill you."

"Yes...yes, yes," Hammer wiped his sweat nervously, and then explained, "but this is really the limit. The outside of the stove looks big, but the space inside is actually limited. And after each furnace is refined, you have to rest for an hour to cool the runes outside the stove, so that the stove must be completely cooled and then re-fireed... After a few moments, it is really the limit to be able to refine fifty kilograms of iron every day!"

"Let the runes cool?" Gao Wen frowned.

"Yes," Hammer explained, "this is just a trick that we ordinary people carved on black stones. It is incomparable to those real magic runes of the wizards. It is easy to break, especially the fire runes. After the fire element is in contact with the fire element, it will crack directly, even if it is replaced with a stronger material, it will not work. Once the runes are cracked, the entire furnace will be scrapped, so it is absolutely impossible to burn continuously when smelting iron..."

"What if the stove is bigger?" Gao Wen asked again.

"There's nothing," Hammer said worriedly, wondering how the Duke Master asked such a problem. "The runes can only provide such a large amount of firepower. If the furnace becomes larger, the firepower will not be enough, and the ore will not be able to refine iron. Moreover, the earth runes will also fail. The refined iron ingots will have more impurities, which will be completely useless..."

Gao Wen pinched his chin: "So the constraints on yields are entirely because of these runes?"

The old blacksmith blinked, but actually didn't understand what it means to restrict yield, but he nodded quickly: "Yes, yes, it's runes."

Gao Wen looked at Rebecca: "You think if you change the rune to...well, why don't you call Hetty over..."

Rebecca suddenly turned red: "My ancestor, I understand magic theory too! I just can't build a magic model..."

"Theoretical knowledge is OK?" Gao Wen raised his eyebrows, "Then how do you think we should solve this problem?"

Rebecca thought hard: "Since you said that runes are a shortcoming, then replace them?"

"What to change?"

Rebecca continued to think: "In fact, the functions of these runes are very simple. They are nothing more than raising temperature, controlling airflow, controlling impurities, etc., and they are the ones with extremely weak effects. If you replace them with real magic arrays, the efficiency can be improved countless times - and the magic arrays can self-distribute energy, and continuous operation will not cause self-destruction..."

Gao Wen raised his eyebrows: "Carn a magic array on every iron smelting furnace?"

"But it's not," Rebecca stuck out his tongue, "Aunt Hetty and I can help carve a few magic circles, but... the blacksmith and blacksmith apprentices can't use them!"
