"Yo, you kid is finally willing to come here as a teacher!"

Lu Lao glanced at Yang Dong, but a flash of joy flashed between his eyebrows.

For him, a cheap apprentice, the more he looked at it, the more he liked it. Especially the many novel theories in the other party's mouth, even if he has never heard of it, many times it sounds like he is half-understood.

But even so, the knowledge in Yang Dong's mouth still benefited him a lot.

"You wait for me first, I'll pack up this material first!"

After Lu Lao said hello, he continued to use his unicorn arm to pick up the sledgehammer in his hand.

"Bang, bang!"

On the blacksmith's table, a burst of sparks flew.

Yang Dong was a little curious, and looked at the piece of material under Lu Lao's hammer.

Like gold but not gold, like wood not wood,

Although it has the texture of metal on the surface, even when it is struck, the sound that comes out is also the crisp sound of metal.

However, its surface is covered with a dense layer of wood texture, which looks very strange.

There is another thing that Yang Dong can't figure out. Because he could feel that Lu Lao didn't just use the power of his body when he was tapping.

The moment he swung the hammer, Yang Dong even felt the surging true qi fluctuations on Lu Lao's body!

In other words, the old blacksmith with an iron hammer in front of him is actually a master of the innate realm!? And this product is still my own cheap master!

Thinking of this, he became even more curious about this piece of material.

After all, there is something about this material that can resist the big hammer of the innate realm martial artist.

Perhaps feeling Yang Dong's gaze, Lu Lao picked up the sledgehammer and explained:

"Boy, at first glance, you didn't take the words of the teacher to heart, and the teacher asked you to study the materials more, but you just didn't listen."

"Why, are you curious now, what is this thing in the old man's hand?"

"Let me tell you, it's called gold wood, and it's a very special mineral, and because of its incomparably hardness, it's generally used to make weapons."

"But this thing, too, has a big drawback, it's like glass, it's too brittle. It's not as exaggerated as glass, but it still doesn't meet the needs of that steam cauldron. ”

So I thought about it to see if I could rely on the forging method to make it more flexible. At the very least, it must be able to resist the force of the steam cauldron. ”

While speaking, Lu Lao's sledgehammer smashed down again.

Only this time, the gold wood under the sledgehammer could no longer bear it, and with a crisp wail, the gold wood on the blacksmith's platform instantly turned into pieces and exploded.

"Hey, sure enough, it still doesn't work."

Lu Lao sighed helplessly, and casually threw the big hammer in his hand aside.

At this time, he was sweating profusely, and it could be seen that the consumption of talent was not small.

He didn't pay attention to Yang Dong, but leaned back on the recliner by himself, held a small bucket in both hands, and poured water into his mouth, the appearance of the whale swallowing made Yang Dong stunned.

"Master, are you so thirsty?"

"What do you think?"

Lu Lao glared at Yang Dong angrily,

"When you were asked to honestly follow the old man to learn to strike iron, you were good, and you didn't learn anything."

"Do you think the old man just knocked and knocked just now? Let me tell you the truth, every time the old man hammers down, he needs a very subtle true qi control. ”

"If the true qi is too strong, this golden wood will not be able to bear it for a long time. Of course, it can't be too weak, because if it's too weak, it won't have much effect after smashing it. ”

"Overall, it's a technical job. How is it, do you have a trace of excitement and plan to learn this craft from the old man? ”

When Yang Dong heard this, he shook his head very decisively.

"No, no need, I'm not interested."

After speaking, he looked at Lu Lao again and asked:

"If the material isn't strong enough, why not consider alloys?"

"Alloy??"

Lu Lao's cheeks showed a look of confusion.

"What is that, why has the old man never heard of it?"

As soon as these words came out, Yang Dong was also stunned.

Because it was only now that he suddenly discovered that Da Zhou did not have the concept of alloy.

So, a lot of the characteristics of metals are actually not well played.

But alloy is a real technical work, even in the ancient times of Yang Dong's last life, generations of blacksmiths have also found some suitable alloy materials after countless attempts.

Therefore, if you tell Lu Lao the method of alloying......

Thinking of this, Yang Dong's face suddenly showed a light of excitement.

"Lu Lao, have you ever thought about what the consequences will be if two different metals are melted and mixed together?"

"Will the metal they form after cooling take into account the characteristics of both metals?"

As soon as these words came out, the expression on Lu Lao's face was slightly stunned, and then he showed a serious expression.

"Xiao Dongzi, the fusion of the two metals is a terrible thing that will happen!"

"I admit that you are very talented in refining weapons, and I also regard it as a talent that surpasses the mantle heir. But have you ever wondered why no one in Da Zhou has ever tried this? ”

This question also asked Yang Dong a question.

yes, why?

It's not that difficult, why doesn't anyone think of it?

Sure enough, Lu Lao saw that this kid was at a loss, so he had to helplessly explain:

"In fact, it is very dangerous to mix two metal solutions together without authorization, so that even now, it is still strictly forbidden."

"Do you know that in our Lu clan's inheritance, there was originally a person with amazing talents. He already has his own experience in refining weapons, and wrote a book of refining instructions based on this. ”

"However, this refining note stops at the last chapter—metal fusion."

"At that time, this senior, according to your idea, mixed the two metal solutions, and as a result, there was a violent explosion, so that this senior didn't even leave a body, and in the end he just left a clothed mound."

Speaking of this, Lu Lao's face showed a look of pain.

After all, for a person like him, who regards refining weapons as his lifelong pursuit, the loss of such a talent is actually the most regrettable.

But at this moment, Yang Dong spoke again.

"I admit that there is a certain danger in doing so, but don't you think it's a bit arbitrary to deny a possibility altogether because of a failure?"

"I don't dare to say anything else, but the alloy method will definitely work!"
