"Could it be that there are small furnaces for sale on this airship?" Feng Zhen continued.

"No, there's no such thing for sale on this airship. ”

"Then where are we going to find it?" Feng Zhen was also speechless.

"Of course it was with me, although it wasn't sold here, but I went to buy something before I left. Bing Yan said slowly: "At that time, I bought a beginner furnace by the way, as well as five kilograms of star iron ore, all of which are in my space ring. ”

"That's great!" Feng Zhen was also very happy. In fact, he had thought about buying a furnace before, but gave up because it was inconvenient to carry. However, he had forgotten that Bingyan had a space ring! his space ring could hold as many things as a room, and it was not a problem to install a training furnace at all.

"There are quite a few empty rooms in this airship now, let's rent one and try it inside. ”

"Okay!"

Feng Zhen hurriedly rented out a room, and then the two of them temporarily set up a smelting room here. And Bing Yan also moved this beginner furnace out of the space ring.

It was a furnace made of black stone, and this stone had a higher melting point than Star Iron, so it wouldn't melt with Star Iron. The top is the mouth where the ore is poured, and the bottom is a heating device, which is where the fuel is placed.

The principle of smelting is very simple, that is, the star iron in the star iron ore is melted through heating, and the impurities are peeled out at different temperatures.

Because the structure of the star iron ore is complex, it is not just a matter of simply melting the star iron, according to the records of the "Forging Encyclopedia", there are more than ten kinds of impurities in this star iron ore, and they need to be heated to five temperatures, and different magic is used at these five temperatures to peel off all these impurities.

After these impurities are peeled off, the molten star iron in the furnace body is poured out and cooled, and the pure star iron ingot can be obtained by processing it.

"Brother Bingyan, let's start!"

Feng Zhen looked at the star iron ore not far away, and a fine light flashed in his eyes.

"Wind Blade!"

The next moment, Feng Zhen also urged magic, and several wind blades burst out from in front of him at once, directly cutting the star iron ore into several pieces. The star iron ore brought by Bingyan was very huge, and it was obviously impossible to stuff it directly into the furnace.

Because he was born in a mining family, he can be said to be handy at cutting star iron ore, and it didn't take long for this huge piece of star iron ore to be cut into many small pieces by Feng Zhen.

"It just so happens that I'm studying fire-based magic, so let's save some fuel, fireball!"

On this side, Bingyan also pulled a small stool and began to sit under the furnace to heat, originally this heating was to ignite a magic fuel, but Bingyan learned fire-based magic, so it would be good to use magic instead. With his eighth-level magician's mana, it was more than enough to support the entire smelting process.

"Brother Bingyan, I poured the ore into it. ”

Feng Zhen said, and poured the cut ore pieces into the furnace.

"The first temperature point is 1721 degrees, this is the melting point of Star Iron, Brother Bingyan, let's heat it to 1730 degrees. Feng Zhen looked at the thermometer that came with the furnace and said slowly.

This first temperature point is also the heating temperature of their Black Iron City process. After heating to this temperature, the star iron ore will turn into a mixture of solid and liquid, and their method is to filter out the solid, and then use magic to peel off the impurities in the remaining liquid, and the star iron is obtained.

However, they didn't know that the filtered solid also contained a large amount of star iron, but they didn't know what to do with it, so they threw it away. This is the main culprit of their low production.

In Master Martin's book, however, he describes the method of further processing these solids, refining more star iron. Now what they have to learn is these follow-up methods.

All in all, take one step at a time, and after the operation, their understanding will definitely be more profound.

"1700 degrees, 1720 degrees, 1731 degrees ......"

After reaching a similar temperature, Bing Yan also controlled the strength of the fire element, keeping the temperature fixed at around 1730 degrees, which was a very challenging operation for magic manipulation, but for him, it was a piece of cake.

"It's almost the wind vibration, use the magic of stripping away impurities. Bingyan looked at the furnace in front of him and said slowly.

"Yes!"

At this time, Feng Zhen also stepped forward and hurriedly used the magic of stripping off impurities. This magic magic that strips away impurities has a wide range, and the basic six systems all have corresponding magic, and the wind system of wind vibration and the fire system of ice flame have corresponding ones that can be used.

However, in this series of magic, wind magic has the lowest requirements, and magicians of other systems can only refine it if they need a sixth-level magician, while a wind-based magician can do it at level four. In other words, the wind mages actually have a slight advantage in smelting star iron ore.

In addition, Feng Zhen is familiar with the process of this first step, so this first removal of impurities is also very smooth.

I saw him close his eyes and urge the magic power, and a magic spell like a green leaf also appeared in his palm, he put his palm on top of the furnace, and the next moment, many black impurities also gushed out from the melted star iron water, and were sucked in front of his palm in the air.

These black impurities also naturally gathered into a pure black ball, and then it became larger and larger, and after about a minute, the melted star iron water did not gush out impurities again.

"Ah, it's burning me!"

At this time, Feng Zhen also threw the black sphere in his hand directly into the bucket at the fastest speed. Although he used mana to defend, with his strength as an eighth-level magician, it was difficult to resist such a high temperature.

Originally, this step should have been sucked out with a special tool, but they didn't have it around him, so he could only use his hands directly, and the result was also very miserable.

Regardless, the first step is now complete.

If the wind vibrates their process, this smelting will end here. Those solids that have not melted are directly filtered out, because they have no way to deal with them, but this book of forging has a way to deal with it. This is done by continuing to heat up to 1800 degrees Celsius and using another magic to suck out another impurity.

"Brother Bingyan, let's move on to the next temperature point, 1800 degrees. Feng Zhen kept rubbing his hands, like ants on a hot pot.

"Ahem, Feng Zhen, I'm really sorry, I forgot to tell you something. ”

Seeing that Feng Zhen was so hot, Bingyan also smiled bitterly, and his expression suddenly became a little embarrassed: "Actually, when I bought this furnace, the people over there also came with a full set of tools......
