Qiu Shui is the same color, the blade is like a dragon's teeth, a little movement, the sky will roar and scream.
"Okay, okay!"
The old man was obviously excited. Looking at the long sword, his eyes were bright... It was scary.
After watching it for a long time, he resisted the urge to try to slash, reluctantly returned the long sword to its sheath, and then carefully returned it to Lu Yu.
Lu Yu reached out at will to take it, hung it around his waist.
In the meantime, this thing accidentally hit the table next to it, and with a ding sound, the old man was gnashing his teeth, and hurriedly said to be careful.
Lu Yu really thought about it for a while, and then said: "Old man, in fact...Basic forging method, what Elder Wu said... I must know it."
"Oh? That's right, how could the red nose not know about such a big thing? Hey..."
"So even if the old man learns the basic forging method, he may not be able to win back a few points from Mr. Wu, or... Well, I have a craft here. Why don't you give it to me? If the old man wants to see... "
"Think about it!"
Lu Yu didn't talk about teaching. Although there is a saying that there is a sequence of skills, a young man really wants a scumbag old man to treat himself as a master... This mentality is a bit abnormal.
With a wry smile, Lu Yu said: "Okay, please pay attention to the older generations. There are some things I learn, but I don’t know how to teach others. If you want to ask me about the details... I only understand, I can only go. I did it, but I didn’t know it and couldn’t tell."
The old man said, "Okay, do it then."
Lu Yu smiled lightly, then looked around, and took a piece of the most common metal. The type was like iron, but it was much denser than iron.
Take it in your hand and check it with the microscopic control method, and you will know the characteristics of the entire metal, how hard it is, how ductile is, how tough is it, as well as melting point, specific heat...
Then the fire is lit and the metal is thrown into it.
While waiting for the burning, he said: "In the basic forging method, it is relatively... Well, the deep place is quenching."
"Quenching? Oh! By the way, you Jiuxiao Longyin, I heard that when it was forged before, it was obviously curved. Everyone thought it was a scimitar. As a result, it suddenly became straight during the quenching process. It's amazing!"
Lu Yu said: "Yes, quenching is actually a superficial method to change the microcosm, how can you say it? Any metal, small and medium, has its specific arrangement. According to these differences, Will have different effects and functions. The way to change them is often through heating or cooling. Quenching is to use rapid cooling to make the metal harder. Simply put, it is to make it change. It's very brittle. When it's brittle, it's sharp, and it's not easy to roll the edge. The retention of the edge will become very good..."
Lu Yu talked a lot, explained the characteristics and importance of quenching, and also explained the core principles. As for whether you can understand it or understand it, then Lu Yu doesn't care.
Finally, the iron piece burned red, and Lu Yu took it out, and the small hammer hit it wildly.
This time it was useless, it was burning, beating, that's all.
Over and over again, especially in some places, Lu Yu beat it strangely. He had already beaten a piece of iron into a dough, like a pancake, but then he beat it into a ball.
Hmm... It's just a ball, back and forth, thrown into the stove three times in total, I don't know how long it took, but it's just a ball...
It doesn't look very round, but it looks like an ellipse, with sharp sides on both sides, and a stick sticks out from below, very thin.
Everyone looked at this strange thing, and the old man couldn't help asking: "Is this... a hammer? There are many people who like this kind of weapon, the better one among the blunt weapons."
Lu Yu smiled softly and said nothing.
The old man couldn't bear his loneliness, and continued to ask: "But this thing... does it have anything to do with quenching? I always feel... Since it is a hammer, it is better to have a little toughness. If it is too hard, it will break easily."
Lu Yu still didn't speak.
As a result, the old man was irritated and even rubbed his hands.
The teacher next to him looked at him and couldn't help sighing. He secretly said that Lu Yu was too innocent to be a human being. He said that he had made a very good skill, and then he made such a thing? It's really... too private. In fact, as long as you have a good relationship with this old man, isn't Shuge just entering if you want to? Unexpectedly, a person who has always been generous suddenly became stingy and wasted such a good opportunity. It is really... a pity.
I wanted to mention something, he said, "Um... Xiaoyu, we don't understand this, otherwise... Change another one?"
Lu Yu smiled and said, "What is not understandable is valuable, isn't it?"
"This… "
The corner of the teacher's eyes twitched twice, and he didn't bother to say anything.
At this time, Lu Yu threw the iron ball into the furnace again. This time, it was the fourth time to enter the fire.
However, Lu Yu's movements were a little strange. He didn't put it there waiting for the iron ball to be burnt red, but kept spinning, making the iron ball look like a drill bit, which looked a little ridiculous.
Only the old man still watched for a moment, as if he was expecting something, and he was also constantly remembering, for fear of missing a subtle link.
The next moment, Lu Yu took out the iron ball, then looked at the pool next to him, and said, "This... you should pay attention to it. It's best to use energy, otherwise... I'm afraid everyone won't be able to see it clearly."
"Oh… "
The two people subconsciously agreed, and the teacher didn't care about it, but the old man's eyes widened and looked at it seriously.
in fact…
These are not the only people present.
It's a coincidence. Mr. Wu is free today, so he wants to come over to the old man to beg for a drink. This guy, because he is in control of Shuge, so popular, there are many people who secretly give him some gifts.
This old man has two things that he likes the most in his life. One is forging. Needless to say, it's like the more stinky you play chess, the more addicted he is. He is obsessed with forging. The other is wine.
For forging things, no one can give anything, so it's wine, he has good wines from all planets and forces! There is no shortage of precious and delicious ones.
But when Mr. Wu came over, I saw people from the junior college coming from a distance. In fact, I originally planned to leave. After all, if there are outsiders, begging for a drink or drinking... Isn't it known? It would be ashamed.
But then I saw that Lu Yu and Xiao Ruan were left behind, and then led to this factory...
What else can I say? Naturally... I ran over and took a peek.
So at this time, when Lu Yu finished saying that he wanted everyone to use his ability to'see', he also opened his eyes wide, watching Lu Yu's movements curiously.
Lu Yu smiled lightly, and then said, "What... Everyone, don't blink."
With that, he stretched out his hand and waved it and threw the'hammer' directly into the sky. It is strange to say that the front should be heavier, it should be big head down, but the hammer is the thin stick underneath it steadily. Then safely pierced directly into the water, and entered it with the iron ball.
The length Lu Yu calculated was just right.
After the thin stick enters the water, it hits the bottom immediately, and then pierces the bottom a little bit to fix the whole. In this way, half of the iron balls above are in the water, and half are exposed to the surface...
At this moment...
Hey! Hey! The sound of water explosions was constant, quite harsh, and a burst of white mist rushed out suddenly. If the factory building was not big enough, it might fill the entire space.
And at this moment...
Three guys who have rounded eyes and can see through the white mist with their abilities...
I just saw... a very incredible scene happened before my eyes.
