The furnace is really good, the furnace temperature is quite high, and the furnace temperature is very uniform. It didn't take long for the iron ore to be burned off, the molten iron slowly gathered together, and the ore slag was discharged. However, that small piece of thunder iron has not melted for the time being.

Thunder iron is a special thing, and it is formed under the long-term bombardment of lightning, so it is more resistant to high temperatures. Normally, the blacksmith burns it until it is semi-soft and then starts to beat it directly. Therefore, to forge a weapon, a large amount of thunder iron is required.

Only when the furnace temperature is extremely high can it be completely melted into molten iron. Seeing Niu Er's furnace today, Du Feng wanted to try it. The molten iron that had been burned before began to shrink, because the temperature was too high, causing some of the components to vaporize and volatilize.

Well, at least this stove is not bad at removing impurities. I just don't know if I can completely turn thunder iron into molten iron. If you want to completely turn the thunder iron into molten iron, you need to strip the lightning from it first.

"Zlazra......"

Just when Du Feng was half-convinced, he suddenly heard a string of noises coming from the hearth. Then I saw a bright blue arc of electricity, peeled out of the thunder iron. Without the protection of this arc, the piece of iron immediately turned into molten iron, fusing with the molten iron before.

"Brother Du, look at me!"

Du Feng is trying to divert the molten iron out and put it into the mold to cool. Xiao Hei suddenly skewered out, and without saying a word, threw a thunderball into the hearth.

This...... Du Feng wanted to stop it, but unfortunately it was too late. Because Xiao Hei's thunderball is extremely powerful, even a seventeenth-level demon beast can be blown up. If you throw this thunderball into it, I'm afraid it will blow up someone's furnace. I don't know how much this thing is worth, but I hope I can afford it.

Du Feng was ready to lose money, but the purple thunderball did not explode, but suddenly burrowed into the puddle of molten iron, and then fused with them. After the molten iron is channeled out, the red is mixed with flashing purple, which looks quite beautiful.

"No, man, you can still make your own thunder iron, wouldn't that be rich. ”

Originally, Niu Er didn't have much confidence in Du Feng's forging skills. With this thin skin and tender meat, he looks like a blacksmith, and he is almost the same as a boy who reads. But he didn't expect that he threw in a pile of iron ore and a small piece of low-grade thunder iron, and actually made so many thunder attribute molten iron.

Not only has the number of these thunder-attribute molten iron increased, but the key is that the thunder-attribute yuan power has also increased, which is equivalent to upgrading out of thin air.

"Hey, it's a fluke, it's just a fluke!"

Du Feng also knew that he had earned it, and this was mainly due to Xiao Hei. However, after Xiao Hei threw the thunderball, he went back to the small world of the necklace. He introduced the molten iron into the mold and waited for it to cool halfway. He clamped it onto the forging table with pliers and began to beat it with a clang.

Du Feng's best weapon is a sword, and the weapon he is best at crafting is also a sword, so this time he is still fighting a sword. As the regular beating sound continued to sound, Niu Er could now be sure that Du Feng really knew how to forge and was not a simple son.

In fact, Du Feng himself didn't expect that this time the forging would be so smooth. The last time I was in this state was in someone else's forge. It's because there was once a master who forged there, leaving a trace of inspiration that he used to use, and he only succeeded once.

This time, Du Feng found that feeling again, as if someone from outside the world was personally guiding him. Every time the hammer is struck, there is a feeling of being possessed by a master.

"Wow, you won't be my father's new apprentice, deliberately sent to tease me. ”

Niu Er found that Du Feng's forging technique was very similar to his father. Especially when the hammer is struck, the technique, the posture, the strength, and even the eyes are very similar. It is impossible for the forging method of the Niu family to leak out, unless it is taught by his father himself.

"I haven't even met your father, how can he be his apprentice. ”

The first beating was over, Du Feng quenched the sword embryo, and then proceeded to the second round. Thousands of tempers are made into steel, even if it is purple thunder iron. It takes thousands or even tens of thousands of times to hit a good sword.

After the sword body cools down, it is mainly the color of bright silver. However, there are purple vertical lines on it, which looks quite beautiful, and this is the effect of purple thunder iron.

In this way, Du Feng was forging over and over again, while Niu Er was watching carefully from the side. He found that Brother Du's forging technique was still different from his father's. While there are similarities, there are also differences.

Originally, it was agreed to continue the competition the next day, but Du Feng didn't stop his work at all, and Niu Er didn't mention the competition, but stood there and watched stupidly. When it was dawn, neither of them had a trick.

"Jingle ......"

Du Feng continued to be busy, and Niu Er continued to watch. This continued for seven days in unison, and on the eighth day, a buzzing sound was suddenly heard, and the newly forged sword trembled on its own.

"The sword is born, and it is to suck blood. ”

As soon as Niu Er saw this situation, he knew that the sword had been successfully built. This kind of superb sword is born, and you must first absorb enough blood. Therefore, there is also a saying that when a sword is born, it will hurt one person. In fact, the sword was not born to indiscriminately hurt people, it chose whoever was the master would hurt whom. sucked your blood, and will follow you in the future.

To be honest, Du Feng was really a little embarrassed, he knew that this sword was of a very high grade, but he was reluctant to give up riding the dragon sword. After all, the Dragon Sword is a sword that can continue to grow. Although the grade is not high for the time being, there is still a long way to go to grow in the future.

"Submit!"

Du Feng first burst into a shout, then bit the tip of his tongue and spurted a mouthful of blood. The blood on the tip of the tongue is where the essence of the human body is located. This squirt up, and the Purple Thunder Sword immediately stopped trembling and obediently fell into his hand.

Du Feng knew that this was a good sword because it had already reached the level of an immortal weapon. Immortal weapons and magic weapons are completely two concepts, and many Da Luojin Immortal Realm martial artists have risen to the cultivation level, and they may not be able to buy immortal weapons, so they can only use the best innate magic weapons first. Theoretically, the effect of the best innate magic weapon should be comparable to that of an immortal weapon.

But that's not the case, because the two are completely out of the same category. The best innate spirit weapon, the effect can be comparable to that of a magic weapon. The effect of the best magic weapon can also be comparable to that of a low-grade innate magic weapon. However, the best innate magic weapon cannot be compared to an immortal weapon, and even a low-grade immortal weapon cannot be compared.
