Bruce brought a few blacksmith apprentices to work. The slaves pushed a material cart and sent hundreds of pounds of scrap iron into the blast furnace. The blast furnace was hot, and the temperature of the entire blacksmith shop was at least 50 degrees.
Bruce was bare-chested and only had a piece of cloth wrapped around his crotch. He directed the people to heat the blast furnace. Because there was no coal in Suhlen, the blacksmith shop used charcoal for heating.
The heat provided by charcoal was limited, only 700 degrees. Of course, this was in an open environment. If it was in a furnace, the temperature could reach 900 to 1,000 degrees. The temperature needed for steel smelting was at least 1,000 degrees. At this time, bellows were needed to help the combustion. Only in this way could the temperature reach the iron smelting temperature.
Suhlen didn't know much about iron smelting, but he remembered that after heating the air in advance and injecting it into the furnace, the temperature of the furnace could be increased by about 200 degrees. In this way, the temperature of the furnace could reach 1,200 degrees, which was not much lower than using coal.
In fact, although there were many advantages to using coal to smelt iron, such as fast smelting speed, high output, low cost, etc., there was a serious drawback. That was the sulfur content of coal. Most of the coal had a high sulfur content. If it was used to smelt iron, the iron would also contain sulfur, which would lead to a serious consequence: the iron would become brittle.
The quality of the iron would decrease, and the weapons forged could not be compared with the weapons without sulfur. When the weapons were cut, they would even break directly. This situation could not be compensated for by the low cost.
After all, no matter how low the cost was, if the things bought could not be used, then the money spent would be worthless.
As for steelmaking, Suhlen also knew a little about it. The difference between steel and iron was the amount of carbon. If the carbon content was high, it would be iron. If the carbon content was low, it would be wrought iron. However, Suhlen really didn't know the specific ratio.
"If I knew that I would travel, I would have memorized all these knowledge points." Suhlen rubbed his head and complained.
Although he didn't know the exact amount of carbon in steel and iron, as an experienced blacksmith, Bruce still had some experience. Under the leadership of Bruce, several blacksmith apprentices set up the first class anvils and heated up the iron ingots that had already been smelted into iron ingots before hammering them.
This method of repeatedly hammering and heating iron ingot was to forge steel. After the iron ingot was repeatedly tempered, it was called refining. After this operation was repeated for a hundred times, it was called refining steel. It was also the best steel on the market at present. Weapons forged with this steel were the best of the best. In the Kingdom of Florence, most of the weapons and armors used by the army were usually refined 30 times.
Of course, there were also weapons that were better than this kind of well-tempered steel. Of course, although the technology of the Dwarves was higher than that of the Humans, in fact, it was also very difficult for the Dwarves to forge well-tempered steel. It was just that they had other secret techniques.
After seeing that the blacksmith shop was producing normally, Suhlen began to look for ways to make money. The territory had been investing in but not producing, which was also very stressful for Suhlen. When Johnson left, Suhlen gave him a hundred Kinnar. Now, he only had two hundred Kinnar left.
There were still some things in the storage space. Two pieces of fine iron, some gems, and two silver treasure chests. The gems were the rewards from defeating the natives last time. Suhlen checked them. Most of the gems were of average quality. Only two of them were of good quality. If he sold them to a gem merchant, he could sell them for three to four hundred gold coins at most. This amount of gold coins would probably be spent in a month.
It would probably take at least two years for the territory to be self-sufficient and have income. At the thought of this, Suhlen wanted to rob the giant dragon's treasure. Legend had it that giant dragons were very rich. Of course, he could only think about it. Not to mention that giant dragons were very rare now, just the power of the giant dragon itself would require at least the legendary level to fight against it.
"Right, there are still two treasure chests that haven't been opened." After saying that, Suhlen chose to open the treasure chests.
With a flash of light, the treasure chests disappeared, and the sound of a system notification rang in his ears.
"Congratulations, Host. You have obtained a mechanical control book."
"Congratulations, Host. You have obtained a bottle of Big Dipper Heavenly Elixir."
"Mechanical control? What's this? " Suhlen picked up the book and flipped through it. The book recorded the creation, principles, and uses of various machines. After reading the system's introduction, Suhlen understood that this was a new skill that the system had created after integrating with this world.
In the original game, this skill was Mechanical Control. It could summon mechanical soldiers such as wooden oxen. However, after coming to this world, it had become Mechanical Control. Moreover, even if he learned it, he wouldn't be able to create wooden oxen. He still needed to improve it.
This time, the system didn't cheat him too much. It gave him an upgrade route. First, he needed to upgrade Mechanical Control to Advanced. Then, he needed to learn the Mechanical Control Secret Technique. After learning the Mechanical Control Secret Technique, he still needed to find an NPC. After the Peach Blossom Immortal passed the NPC's test, he would receive a reward. This reward was awesome. It was actually the creation of Puppet Magic Statues.
This system actually gave him the creation of Magic Statues. It directly turned some of the iron men in the game into Steel Magic Statues. Suhlen had never seen a Steel Magic Statue before. However, he still knew of its reputation. A Steel Magic Statue had no problem sweeping through a group of knights. Take note that it wasn't a group of knights, but a group of knights.
Let's not talk about the Puppet Magic Statues for now. Who knows where to find the Peach Blossom Immortal? In the game, the Peach Blossom Immortal could be found as long as he went to the peach forest. Where could he find him in real life? This broken system didn't even give him a hint.
Although he couldn't create Mechanical Puppets, Mechanical Control was still useful. For example, he could create some simple mechanical tools to speed up the construction of his territory. He could also create a Hydraulic Forging Machine and a Hydraulic Blower for the Blacksmith Shop.
With the Hydraulic Forging Machine, the speed of forging Tempered Steel would increase by at least ten times. After all, how could a human hammer compare to a machine? Moreover, the machine hammered at a uniform speed and had sufficient strength. Originally, he wanted to find some blacksmiths to research it. Now that he had this Mechanical Control Manual, he could definitely create one himself.
After learning Mechanical Control, Suhlen picked up a glass bottle beside him. The bottle was filled with a blue translucent liquid. As the bottle shook, the liquid inside flashed with specks of starlight. It looked very beautiful. This item was also very rare in the game. Its effect was very simple. It increased one's attributes.
[Big Dipper Heavenly Liquid: A mysterious liquid formed by the convergence of the power of the stars. After use, it can increase one's strength or vitality. After use, it can increase one's strength or vitality by 3. Only one effect can be triggered at a time. Can be used repeatedly.]
