"Ah, Brother Bingyan, why didn't you say it earlier!"

Feng Zhen was directly dumbfounded.

"Well, I forgot about it for a while. Bingyan also scratched his head.

After that, Bingyan also took out the matching tools, and then, they heated it to the second temperature point of 1800 degrees, and Feng Zhen also used another magic to extract the impurities according to the method in the magic book.

This second step is completely new for Feng Zhen. Because the magic used in the second step is not recorded on their side at all, and even if they can heat it up, it won't help without that magic.

But fortunately, the introduction of that book is very detailed, coupled with Feng Zhen's strong learning ability, after practicing four or five times, he roughly grasped the main points.

This is followed by the process of repeating this step. Heat to a higher temperature point, then bring out new impurities with new magic. Of course, as the steps progress, the magic becomes more and more difficult, and the requirements for mana become higher and higher.

However, after several attempts, as well as Bingyan's explanation, Feng Zhen finally successfully used this last magic.

"It worked!"

In this last 2150 degrees, all impurities have been removed, and the molten iron left in the furnace is now pure star molten iron.

After that, they also cooled the star iron water, and then obtained the finished star iron ingot.

"Brother Bingyan, we succeeded!"

After seeing this silver shining star iron ingot, Feng Zhen was also extremely excited. It seems that there is no problem with the methods in this book at all, since they can refine successfully, then it must be easier for my father's people.

And Bingyan on the side is also very accomplished, after being reborn for so long, he also found the happiness of a novice upgrade for the first time.

"Feng Zhen, take a look at the color of this star iron ingot, what kind of quality is it?" Bing Yan blinked and asked Feng Zhen again.

In fact, he doesn't know much about forging, but Feng Zhen has been exposed to Star Iron since he was a child, and he should be able to judge the quality of Star Iron Ingots.

"Seems to be D, oh no, C-grade quality. Oh my God, this first refining time, I can refine a C-grade quality Star Iron Ingot! It seems that the upper limit of this refining method is still very high, if I am more proficient in magic, maybe the quality can be even higher!"

Feng Zhen said, his eyes became more and more excited, this smelting method is not only higher than theirs, but also a lot higher quality, as long as he studies carefully, he may be able to refine A-grade star iron ingots.

The same star iron ingot, the quality level is different, and the price will be far different. As long as my father's side can master this set of techniques, then I don't need to sell Star Iron Ore, but directly export Star Iron!

If this industrial upgrade is completed, it will be a big deal, and their mountain city will be even richer than it is now.

"Brother Bingyan, I'll write a letter now and tell him about this latest smelting method!"

Thinking about these things, Feng Zhen couldn't suppress the excitement in his heart.

"Go ahead, but remember to remind your father to keep it a secret, so as not to attract the eyes of the people around him. Bingyan also reminded in passing.

"Understood, thank you, Brother Bingyan!"

After Feng Zhen finished speaking, he happily wrote a letter.

"This forging book is really surprising...... Bing Yan looked at this "Forging Encyclopedia", and still felt a little emotion in his heart.

In the interval when Feng Zhen left, Bingyan also put the furnace into the space ring, sorted out the location of the items in the ring by the way, and then looked at it in advance.

The previous part talks about how to refine star iron ore into star iron ingots, while the latter part talks about how to make star iron ingots into star iron weapons. Now the part he is looking at is about how to build the Star Iron Sword.

Bing Yan flipped through slightly, and found that there were star iron shields, star iron armor, star iron spears, star iron knives, and all kinds of star iron weapons behind him, all of which would be clear. Behind this, it is even stated whether this metal can be enchanted or not.

"It's worthy of "Forging Daquan", this content is really complete. ”

Looking at the content here, Bing Yan was also very emotional, it seems that after reading this book, as long as there is ore, it can be turned into a weapon! And this is only the Star Iron Chapter, and there are all kinds of metals in the back.

Thinking of this, Bing Yan also flipped through the catalog of this "Forging Encyclopedia".

"It's not just metal?"

After glancing at the catalog, Bingyan was even more shocked. In fact, this kind of forging book, he thought it was just a weapon for forging warriors, but when he took a closer look, he found that the refining of many magic crystals and the production of magic wands were also on it.

He said why this first volume is so thick, and it turns out that the quality is so sufficient.

"If Feng Zhen learns this book, my future weapons will be lost. ”

Looking at this "Forging Encyclopedia", Bingyan couldn't help but smile slightly.

Although he now has a thundering sword sent by Wu Ye, to be honest, he doesn't use this sword too easily, and the magic attached to it is thunder magic, which is not compatible with his fire magic.

So, if you can change the weapon, that's also the best.

"After I get to the four major academies, let Feng Zhen give me a weapon to take advantage of, and Lot, let him help get one too!"

At this time, Bingyan also suddenly had a magical idea. Although he can pick it out outside, let Feng Zhen help him do it, first, he can do his homework, and second, he can take care of his business. Moreover, he can also participate in the alongside of him.

"It's decided!"

After thinking about it for a while, Bingyan also immediately made up his mind. However, since it was for practical use, the lowest grade star iron was certainly not enough, and he wanted to pick a metal that was more advanced than star iron, but it would not be too difficult to get.

Thinking so, he also began to flip through it. At the back of the book is a metal introduction sheet, so he can also take a good look at it.

"Flame Steel, an F-class metal with fire attributes, is a weapon made of metal that can be infused with fire magic. If the user is a fire mage, the metal also increases the user's mana. ”

"That's you. ”

Looking at this introduction, Bingyan also nodded. This kind of metal can be said to be the first choice, first of all, he is F-level metal, and it will not be too difficult to refine, and secondly, he is much higher than Star Iron, which is just right for him at the mage level.

"Brother Bingyan, I'm back!"

After some time, Feng Zhen also came back after writing a letter, however, when he just entered the room, he found that the atmosphere was a little strange. Because at this time, Bingyan was looking at him with the eyes of looking at his prey, and there was a strange smile on the corner of his mouth.

"Brother Bingyan, what's wrong?" Feng Zhen was a little puzzled.

"Hehe, Feng Zhen, tell you something...... Bing Yan smiled, and also put on Feng Zhen's shoulder.
