Lu Yu touched his nose, because the process of adding power was his constant beating and burning.

The so-called tempering may be just steelmaking for others, but for Lu Yu, it is to refine the strength into it.

For people in this world, I am afraid that there is only one Lu Yu who really agrees with the word 'refining'.

What is forging to him? There is a tiger in his heart, and he smells the peony.

"But then again," Lu Yu smiled, "Those guys who were cast are more suitable for such a miracle blowout, right?"

Wu Lao laughed and nodded: "Yes, after all, the metal ore comes out directly in liquid form, and it can be cast directly into the mold, but the success rate is very low, after all, until the end, I don't know what will be cast." ”

"Well......" Lu Yu nodded and said: "Yes, after all, the temperature in this volcano is too high, all metals are mixed together, and even the rocks are melted, and the rocks are rocks, and after they are cooled, they are just simple stones, so the success rate of casting is naturally low." ”

"Oh, so that's the reason?" Wu Lao widened his eyes, and then said, "yes, everything melts together, and it will indeed be troublesome...... But what if you want to separate them?"

Lu Yu smiled lightly and said, "This ...... It's very simple, each substance, some is close to each other, some is far away, in fact, the melting point is different, as long as you master this, you can completely separate them. ”

Wu Lao thought about it carefully, then his eyes lit up, and he said: "Oh! Just use the mining method of ore? Yes, why didn't I think of it before? If you want to mine ore, you have to use the melting point to refine the metal from the rock, but how to put it in the forging, and forget this foundation? Hey...... Really. ”

Lu Yu smiled: "This is a ...... It's easy to think of things, but the reason why you can't think of it is because the forging technique doesn't pay attention to the basics, and then there is a fault in the middle? People who are just starting out are still struggling, and as long as they cultivate to a certain extent, they can use qi forging like you, so there are some places in the middle that need to be specialized, and no one will carry out this work, and this is the fault. ”

"Oh, I see!" Wu Lao nodded heavily, and at the same time he breathed a sigh of relief, after all, this at least proves ...... The Forge Academy isn't that stupid.

Suddenly, Lu Yu asked, "By the way, I remember the first time I met Wu Lao, there seemed to be a young man next to you, always squinting his eyes, right?"

Wu Lao was stunned for a moment, and said: "Oh, you said Wanghai, that's an idle person, the college wanted him to teach there a long time ago, but this guy just didn't go, anyway, he was a weird person, but his popularity in the martial arts academy was still good...... Well, why did you suddenly remember to ask about him?"

Lu Yu shook his head and said, "Oh, it's nothing, I saw that you were together before, and I thought he was also from the Forging Academy." ”

"Hahaha, of course not, but I really had plans to bring him to this forging academy, after all, he is really quite a genius, although each item is not too outstanding, but it is average, and the forging level is far higher than the general teaching of our intermediate academy, if he can come, it will naturally be a good thing." ”

"That's ......"

Lu Yu smiled lightly, and then continued to look at the crater, obviously without any intention of continuing to chat.

Wu Lao also smiled, so he didn't say anything, and went to patiently prepare the things that he needed to use for a while.

But at this time.

There were three people walking nearby.

The first one, with red hair, is obviously an old man, but he looks heroic.

He laughed, then pointed at Lu Yu and said, "I said Wu Lao, this is the kid you are about to blow into the sky? ”

When Wu Lao heard this, he couldn't help but roll his eyes, then turned his head and whispered to Lu Yu: "Look, trouble is coming, this is the bad old man I told you before!"

If it is a bad old man, compared to the other party, Wu Lao is still more 'bad'.

Lu Yu tilted his head, and then asked, "That...... Elder, do we have any grudges?"

The red-haired old man said, "Hatred? ”

Lu Yu smiled: "Since there is no grudge, why are you talking badly to each other now? This doesn't seem to make any sense, right? What is my ability...... First of all, I'm not a student of the Forge Academy, so you don't seem to have the right to judge. Secondly, when did I say that my forging level was very good? When did I brag about it? Even if I look a little sparse and ordinary, but this level of forging, I think I still have some ability, and you haven't seen me forging, so you evaluate it so arbitrarily...... Counting these two items alone, you are not wise and unwise to meddle with rats. ”

"You kid with sharp teeth. ”

"It's okay, it's okay, it's been popular lately, and I've been pinching it myself for many days, how about it?

Lu Yuxian's new chin, everyone turned their heads to look at him, they were all sluggish, only Xiao Ruan smiled lightly and said, "Young master, when is it, he is so handsome, it is fascinating." ”

"That's it!Oh, there's no way, it's natural!hahahaha!"

All of them have black lines on their faces.

Even the red-haired old man twitched the corners of his eyes, and then shouted loudly: "You stinky boy...... Are you humiliating me? Okay, well, since you said that you still have some skills in forging, why don't we have a competition?"

Lu Yu pouted and said, "This is going to be a competition, it's a little too sudden, isn't it...... En, that, Elder Wu, what do you think about this matter?"

Wu Lao was stunned for a moment, then glanced at the two people beside the red-haired old man, and then said, "I'm just afraid...... Not so easy to deal with. ”

Taking a deep breath, Wu Lao said: "You guy, with two forging masters in succession, if you compete...... I'll stay with you!"

O only!e positive.@版O,|◎ its 4{ he @ 0 all "\ is 'pirated E version.

The red-haired old man smiled: "How can it be done? The method of forging is not to pay attention to one-to-one, but to pay attention to a team, it doesn't matter more or less, I am also considered to be fair, three thousand protégés are not needed, seeing that there are only three of you, only two people are brought, so our number is considered fair." ”

Wu Lao said: "Fair, one of them is a teacher of the Advanced Academy, and the other is the first person in the Forging Academy, the two people you bring with you, the forging ability is not lost to you at all, and this one of them is ...... In some places, even you are far inferior, but you say it is fair?"

The red-haired old man smiled and said, "What's the matter? I'm afraid? Old Wu, you just need to say that I'm afraid, I'm convinced, it's not our opponent at all, so this competition will be over, how about it?"

"You!"

The corners of Wu Lao's eyes twitched, and then he turned his head to Lu Yu and said, "Why don't we ...... Let's give it a try?"

Lu Yu blinked, then smiled bitterly, rubbed his brows and said, "I said...... Why do you look like children? behave like you, talk like you...... Well, is this the so-called back to basics? Or is it because you don't have to think about anyone's feelings, just like a child who does whatever he wants? Hmm...... It's all possible. ”

Raising his head and looking at the slightly angry group of people, Lu Yu said softly, "Since you want to gamble...... Gambling on this kind of thing seems to be indiscriminate between adults and children, and it has to be all they have to be considered a ...... Gamble. So let's take a look at the adult's gambling method, what do you think?"
