In the process of escaping, Qin Murong went to a corner, looked at the garbage everywhere, frowned, covered his nose and hurried away.

But if you turn left and right, you will see a burning room. The temperature inside should be very high, so there is hot gas coming out.

In this too humid forest, this kind of dry place is a little attractive.

And Qin Murong likes fire.

Human society is the civilization of fire.

The degree of utilization of fire in a place represents the degree of civilization of the place.

So he swaggered in, as if in his own home.

He went straight in.

Inside there is a big stove, next to which two people are desperately pulling the bellows, and next to it is a platform with a lot of sand and several containers.

Qin Murong turned around. The two men saw him. They were surprised and frowned as if they wanted to confirm his identity. After they found that they had no impression at all, they wanted to stop him from walking back and forth.

But now the fire is in a tense moment, I can't delay for a moment, so I can only tolerate him and shout who you are at most.

Qin Murong, of course, turned a deaf ear.

After walking around the room, he took down two swords from the wall and looked at them. He waved them a few times, stretched out his hand to play on them, then laughed and threw them aside. It was very impolite.

Finally, he came to the fire, sighed and said, "it's really backward here. I thought you just live in a poor place. At the beginning, I saw the little saber very well, so I thought you were a place to hide wealth. As a result It's really backward. "

"What are you talking about?"

The man pulling the bellows could not help shouting.

"What? Speak the truth! Just pull your bellows and don't butt in. "

"What? Cut in You didn't talk to anyone... "

The bellows are a little confused.

Qin Murong turned his head and looked at an old man who was coming. He spread out his hand and said, "don't blame me for speaking straight. I just don't like beating around the bush."

The old man looked up and down at Qin Murong, unable to recognize him, but thinking of what happened recently Or ask, "are you Lord Qin

Qin Murong said with a smile: "sure enough, we all know the news of my coming. Oh, by the way, I was kidnapped. You don't have to be too rigidly bound by etiquette or kneel down. I don't like it all the time."

The old man's eyes twitched for a while and then said, "sir Just said it's backward here? Does the LORD have any research on the casting of the blade? "

Qin Murong said with a smile: "research is not enough, just a little heard."

For a craftsman, if you intuitively say that he is not good at craftsmanship, the other party will burst out.

Qin Murong is also boring. Anyway, he has to hide from the wind. It's not a bad thing to make trouble here. Anyway, he has to be familiar first.

He laughed and said, "you are just casting. Casting is a good thing to say, but it's a backward mess. Since human beings know how to use metal, they know this craft, so it's nothing new."

The old man's eyes twitched a few times, but he didn't know how to refute it.

First of all, Qin Murong's reputation is too big.

On the other hand, it is also because what Qin Murong said is true.

Casting is ancient.

There's really nothing magical about it.

However, with the development of human beings, the casting technology is becoming more and more sophisticated, and the one who can really make good things is definitely the existence of master level.

This old man is obviously a master, but Craftsmanship will be killed by craftsmanship!

It's not about personal effort, it's all about the difference between the upper and lower levels.

The old man wanted to bear it, but the guy who pulled the wind box beside him couldn't help it and said in a loud voice: "tie Lao! I can't bear it. We've been here for many years and generations, and then we've been stigmatized like this. We We really can't bear it

Tie Lao sighed and said, "that Sir, you have also heard this. The speaker did not mean to hear it, and the listener meant it. Since Sir said that we are too backward to say I'm afraid the Baron wants to show it. At least he tells us the reason and makes the old man and the dolls feel at ease. "

Qin Murong curled his lips and said, "well, it's boring anyway."

He walked slowly to the table, picked up the long sword he had just thrown there, and then asked, "tielao Is it? Ha ha. "

"No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no

Qin Murong nodded and said, "well, to tell you the truth, my status is a little high. If I add 300 years old yuan to my body, I can't stand it."Iron old man wry smile, this kind of deceiving words, he naturally does not believe.

Qin Murong continued: "old iron man, you sword What's your level? The best? Senior? Medium or something? "

The old iron man took a look and said, "it's not the best, but it's higher than the intermediate level. It's above the medium level."

"Oh..."

In fact, the iron old man said less.

It's really not the best, but it's really advanced! Otherwise he would not have hung the sword on the wall.

Qin Murong curled his lips and said, "how can I say that if it's all advanced I'm a little speechless. "

"What do you mean, sir?"

The old iron man frowned. He didn't know whether Qin Murong thought it was good or bad.

On the one hand, the iron old man has the heart of competition, on the other hand, he also knows that Qin Murong is well-informed, which is better than his own view of heaven at the bottom of the well.

Qin Murong thought for a moment, and then said, "I'm thinking Well, in the end, what kind of wording is used so that you won't feel too hurt. "

"Sir, what does that mean?"

"Well, I'm not the kind of person who can talk. That's it. To be frank, you sword has trachoma."

"Trachoma?"

"It's casting when the metal is mixed with sand or bubbles."

"No way!" Iron old man said aloud: "in order to remove the impurities, generations have carried out a variety of common sense, today's formula, today's method, is absolutely no problem! Don't say it's bubbles or sand, there's no impurity! "

"Yes? So confident? "

Qin Murong curled his mouth, reached out his hand and played on the sword again. The sound of the sword was clear, but the ending was a little mixed and chaotic.

It's a feeling of Indescribability. It's all about experience.

"Listen, do you think it's right?"

"This..."

Iron old man said: "every sword can't guarantee to have absolutely beautiful sound. It's impossible that all swords are the same. You should know that."

"I know. That's why there's a difference between good and bad. Do you think there's no problem with this sword?"

"Naturally, there is no problem! It's not perfect, but it's not going to be that big a problem

"Knock?"

"This..." Old iron gritted his teeth. If he knocked, he really felt sorry. But if he didn't knock, he felt guilty. It took more than three days for this sword to choose materials, then to cast, and finally to polish its fittings. If it was discarded like this, it would be a pity.

But He did!

"Yes, knock!" he said aloud

"Really?"

"Knock, of course!"

"Good."

Qin Murong raised his sword without any stone, so he knocked it gently on the table.

The sound is beautiful. The sword just shakes a little, and then returns to its original state.

"Just That's it? "

Iron old man Leng for a while, some want to laugh.

This kind of knock is a little too childish, not to mention his sword, even if it's a kind of defective product, it can't be broken like this.

Qin Murong said with a smile: "it's not over yet. What's the rush? I'll use this kind of strength and never increase it. "

"What do you mean?"

"Look."

With that, Qin Murong knocked on the sword again and again, looking for a position, and finally found a point, and then knocked on the corner of the table.

The old iron man said, "Sir, if you knock like this, it won't break even if you knock for a year."

"Oh? Is that right? "

Qin Murong laughed and continued to knock. The strength remained the same, but the rhythm changed a little, from slow to fast, and then to slow. Trying back and forth seemed to be looking for a rhythm.

About a cup of tea, Qin Murong found it and used the rhythm to knock it.

Just then the old iron man asked, "Sir, what do you want to knock like this..."

The word "time" hasn't been spoken yet.

With a dull click, the sword suddenly folded into two sections. The first section was on the ground, jingling.

The old iron man's body vibrated with the sound of the broken sword falling. He didn't respond for a long time.

Qin Murong said, "do you know why it's broken?"

Iron old man slowly shook his head.

Qin Murong said with a smile: "impurities, what you call impurities, should be some Foreign matter and other things, but what I mean by impurity is something that doesn't conform to the material of the sword. Even if the composition is a little bit worse, it can be regarded as foreign matter and impurity. For a long sword that often needs to fight with people, it is already fatal! Ha ha, you see the things produced by the Qin chamber of Commerce. What are they made of? Even if it's a common people's kitchen knife, have you ever seen it forged? Why? Do you have anything from the Qin chamber of Commerce? Now the things of the chamber of commerce should be sold all over the world, and you should have some, too? "Old tie was stunned for a moment, then shook his head and said, "this I really don't know. Sir, tell me more about this impurity But even if there are impurities, it's impossible to break it directly, right? It's too easy, isn't it? "

Qin Murong did not answer, but turned to look at the two bellows and asked, "do you know anyone here has bought something from the Qin chamber of Commerce?"

One said, "we don't have businessmen from the chamber of Commerce here. Where can we buy them?"

The other said, "ah, I remember, the cook seems to have brought a kitchen knife from the Qin family chamber of Commerce. She usually uses it, but no one else can touch it. Before, Lao Li wanted to use it. As a result, she was chased by the fat cook for half an hour, which made a lot of trouble."

Qin Murong nodded and said, "go and find me that fat cook's kitchen knife."

"Ah?"

The man said quickly, "I don't want to be beaten..."

But the old iron man gritted his teeth and said, "I'll go and have a look!"

Then he went out of the door and came back in about a quarter of an hour, holding a common looking kitchen knife with the word "Qin" carved in the corner.

Qin Murong took the knife and could smell the smell of green vegetables from it.

He looked around, weighed it again, and said, "well, this is the kitchen knife of our Qin family chamber of Commerce. It's not the worst kind. How can it be regarded as medium."

With that, he turned his head and looked at the blade on the wall. He took a long knife and put it on the table with the blade facing up.

"If you use a sword, the body of the sword is thin and the blade is thin. If you fight against each other, the long sword will suffer too much. The long sword is very good. The blade is open It's wide enough, just like an axe. "

As he said this, he looked at the old iron man and said, "now I use this kitchen knife to chop with your long knife. What do you think?"

"This..."

The old iron man said, "how can this work? How can the kitchen knife be the opponent of the old man's long knife? "

That's what he said, but he was a little guilty.

"If not, how can we know who is stronger? When the blade is almost the same, who is stronger and who is weaker will know? "

"Well All right

In fact, old iron is also a little curious.

But he immediately added, "can I cut it?"

"Naturally."

Iron old man took the knife, looking at the long knife that sharp blade, how don't think long knife will lose.

Raise your arm and chop it down

Poof, it's a strange sound.

Then take it away, you can see that there is a big crack on the kitchen knife, and there is a inch long gap on the long knife! The gap is rolled up!

"This What's going on? "

Qin Murong said: "ah, it seems that quenching is not good, there are also problems."

"Quench Quenching? "

Qin Murong said with a smile: "yes, there is no such process in casting, right? After all, it doesn't need to. The things that were originally extremely hot will be cooled again before they can be cast into shape. If they are quenched again, it is easy for the cast things to deform and crack, which is not worth the loss. "

"So I can't beat this medium-sized sword Can't defeat such a small kitchen knife? "

"Little kitchen knife?"

Qin Murong laughed and said: "what you see in your eyes is a small kitchen knife, but this is actually the peak of the world! This is the key to the Qin chamber of Commerce

"This What's the matter with this kitchen knife? "

"Do you think Would I tell you so directly? "

"This..."

The old iron man's eyes twitched for a while, then sighed and said, "yes, all this kind of craft is the secret that can't be passed on..."

"Oh? The secret of not spreading? It's a bit of a exaggeration. After all, many people in the Qin family's workshop know this craft, but I'm very surprised. Why do you also forge swords? Other people's Fengjian villa also casts swords. Why are they so superior to you? Fengjian villa is good. Although some places are a little too strong, it's still good. "

"This..."

The old iron man was embarrassed and said bitterly, "isn't there only one Fengjian villa in the world? There are many legends about the world's famous swords. Only Fengjian villa can cast the world's top ten famous swords at that time! "

"Oh Qin Murong suddenly said: "no wonder they were so arrogant before. It turned out that they were good in technology?"

"It's not good. It's the top of the mountain. All our lives, we just look at it at the bottom of the mountain. At most, we can climb to the middle of the mountain, but each other will always look up to it."

Qin Murong curled his mouth, because the old iron man's face was full of respect. It was obviously true respect, not disguise.

So he was a little angry.

He said, "if you want to respect me, you should respect me. Fengjian villa? greatly? What a fart! It happens that you have a pot of hot metal here. Come on, let me show you the real technology! "Qin Murong went directly to the iron stove and looked at it with satisfaction.

If there is anything really good and good about casting, it is this furnace of hot metal!

Why is it forged in some places and cast in others?

Why are some places cast at first and then forged?

Because of the fire!

Melting point is absolute, furnace temperature is absolute sometimes.

In the past, people used bronze ware in ancient times. Because of the low melting point of copper, it was easy to be burned into copper water, and then poured into the mold, and then it would be cast. So the most popular casting in that era was casting, not only swords, but also bronze tripods.

However, when people found that iron was much stronger than copper, they pursued it. Unfortunately, the furnace temperature was not enough to melt it and turn it into molten iron. At most, they could only burn it red and soft, so they forced out the "forging" method!

In fact, casting this kind of thing is not as unbearable as Qin Murong said. On the contrary, it is the most primitive and The farthest thing to go.

As for the real technology, even the art, often comes from integration.

When musical instruments are combined with human voice, when dance is combined with drama, when painting is combined with dye Too many things become different because of integration, so that they can climb to a higher level.

And casting and forging, if they can be combined Should not say so, Qin Murong's previous life, is this kind of union!
