Although this longsword is unpolished, it can only be regarded as a rudimentary longsword.

But Xiao Tianxing knew in his heart that as long as it was polished and opened, this sword would be a genuine steel longsword.

Picking up a handful of clean water from the basin next to him and washing his face, Tie Shan also looked at Xiao Tianxing with a smile.

"How's it going? Do you understand the whole process?"

"Well, I get it. Uncle Iron Mountain, your little hammer is pointing out the position, and the brother's sledgehammer will hammer the position you support. ”

"Well, if I'm not mistaken, this sword was forged with twelve thousand hammers!"

"As for the wooden cabinet where the blade of the sword is hammered with a sledgehammer, it is to forge the magazine components in the metal, so that the sword can become stronger and sharper. ”

"Well, yes, yes! You have a good combination of the knowledge in the book and the actual situation in reality. ”

"In that case, I'll tell you some more about it!"

Coming to the tea table outside the blacksmith shop and sitting down, Tie Shan took a sip of tea and began his narrative.

"You're right, but that's just the basics, so that's why I'll let you memorize it first. ”

"As for how to forge a good weapon, in addition to the necessary materials to make the weapon, the forging process of the weapon is also quite important. ”

"Hmm, I'll give you a dozen examples! Take out your steel sword!"

"Oh!" After making a sound, Xiao Tianxing also took out his stainless steel long sword.

After Xiao Tianxing took out the steel long sword, Tie Shan took the steel long sword that had just been made and handed it to Xiao Tianxing.

"Both of these are steel swords, so can you tell the difference?"

"Uh... I'll take a look!"

Staring at the stainless steel long sword in his hand for a long time, Xiao Tianxing shook his head at Tie Shan a little helplessly.

"I don't see the difference between the two of them. ”

"Oh, that's no wonder. After all, you've just learned the art of blacksmithing!"

"So be it! You slash the two steel swords in your hands and see what happens!"

"I'll try!"

Coming to the open space outside, Xiao Tianxing held a sword in each hand, and then slashed the two swords together.

"Dang!" After a crisp sound, the two stainless steel swords in Xiao Tianxing's hands also slashed together, and then Xiao Tianxing's eyes widened.

Because at this moment, the steel long sword in his hands was broken, and the other was indeed still intact.

However, the reason why Xiao Tianxing was surprised was that the broken steel long sword was actually his own open steel long sword.

As for the steel longsword that Tie Shan had just forged, there was no trace of even the interface where they slashed each other.

"It's... Uncle Tieshan, what's going on, why did my steel sword break?"

"Hehe, you bring the two swords first, and I'll explain them to you in detail!"

"Oh!"

Picking up the steel long sword that was broken on the ground, Xiao Tianxing also walked quickly in front of Tie Shan.

Looking at the two stainless steel long swords on the table, Tie Shan smiled and pointed at Xiao Tianxing's broken stainless steel long sword.

"Your general and that long sword can only be regarded as inferior and superior quality. If I'm not mistaken, this sword love forged 10,000 hammers and then came out. ”

"So when it encounters a steel sword with twelve thousand hammers, it will only be cut off. In order to give you a more intuitive understanding, let me show you some more things!"

After saying to Xiao Tianxing, Tie Shan reached out and picked up the steel longsword that had just been forged.

In Xiao Tianxing's puzzled gaze, Tie Shan gathered a thin Source Qi Blade on the two fingers of his left hand, and directly cut off the stainless steel long sword in his hand.

Seeing that Tie Shan actually destroyed the long sword he had just forged with his own hands, Xiao Tianxing's face immediately showed a puzzled expression.

At this time, Tie Shan handed the two broken steel long swords to Xiao Tianxing's face.

"Now if you take a closer look at the difference between the fractures between the two steel swords, you can understand why your steel swords broke. ”

Curiously taking the broken sword handed by Tie Shan, Xiao Tianxing carefully observed the broken place of the two swords.

After careful and careful observation, Xiao Tianxing found that there were some very small pores in the sword bodies at the fractures of the two swords.

However, the only difference between the two swords is that there are fewer pores in the fracture of the sword that Tie Shan just forged, and these pores are much smaller than those in his own sword body.

Discovering this only difference, Xiao Tianxing also told Tie Shan about this discovery.

After hearing Xiao Tianxing's answer, Tie Shan also nodded with satisfaction.

"Yes, you're very observant. Do you know why there are these tiny pores in the sword?"

After lowering his head and thinking for a moment, Xiao Tianxing gave his own answer with some hesitation.

"Is it because the density is not enough, is this the reason?"

That's why. The reason why the sword breaks is also because of these pores. Can you figure this out yourself?"

"Hmm...? I can probably get it. Isn't this the same as the principle of suppressing the source qi when I was cultivating?"

"The density of the source qi that has been suppressed for a long time will increase, and when you fight someone, your source qi attack will become more powerful. ”

Stretching out his hand to touch Xiao Tianxing's head, Tie Shan also smiled and nodded.

"That's right, you're right, that's it. ”

"Just by the fact that you can see the air holes in the sword body just now, and you can understand the truth now, you can be regarded as a real human-level swordsmith. ”

"Now I'll explain to you in detail, the truth in this!"

Picking up the broken sword again, Tie Shan pointed to the location of the broken wound with his finger.

"You have already understood the origin of these blowholes just now, so I will not repeat anything. ”

"So now let's talk about how to make these pores fewer, or completely make these pores disappear!"

"As I said earlier, the best way to make all the magazines in the metal disappear is to do it repeatedly. ”

"And the more times you forge it, the more impurities in the metal can be fully cleaned up. ”

"As I said just now, this steel longsword of yours should have been forged with about 10,000 hammers. ”

"If you put it on a blacksmith with good skills, the number of forges is quite good. ”

"However, after all, 10,000 hammers are only 10,000 hammers after all, so there will still be a lot of air holes in the sword body. ”

"More pores means more impurities, so the hardness and toughness of the sword body will be reduced. ”

"As I said just now, if you want to fully force out all the impurities in the sword body, the best way is to beat it repeatedly. ”

"If you want to completely eliminate the impurities in a sword or weapon, then this weapon has to be tempered a lot. Tianxing, do you know what it means to be tempered by a thousand tempers?"

"I don't know. Between answers, Xiao Tianxing also shook his head blankly.

"Hehe! Actually, it's easy to understand. Thousands of tempers refers to the number of times the weapon is forged, and you can calculate how many times a hundred or one thousand is!"

"A thousand times a hundred, that's... 100,000 hammers! Do you need to repeatedly forge 100,000 hammers to make all the impurities in the weapon disappear?"

Regarding Xiao Tianxing's surprised expression, Tie Shan also nodded with a smile.

"That's right, it's 100,000 hammers, and even if you encounter some special metals, it's not strange to forge 200,000 hammers or even 1 million hammers!"

"That's what 100 steels refer to, and that's what the real steel grows in. ”

"If it's a real steel long sword, he's already a low-level weapon of the third grade of the human rank. ”

"But this is also the highest level of the steel longsword, after all, hundred steel can only be regarded as a relatively good metal. ”

"And as long as you are willing to work hard to make steel, every high-quality blacksmith can forge it. ”

"Although 100 steels are relatively easy to make, the workload of 100,000 hammers is not something that can be handled. ”

"So, the stainless steel longswords circulating on the market now are only some stainless steel longswords of about 10,000 hammers. ”

"But even a long sword of this caliber is worth more than fifteen gold coins each. And for every 10,000 hammers wrought, the price of the weapon doubles. ”

"So with the exception of some rich people, ordinary soldiers simply cannot afford this weapon. ”

"Oh, that's right!" nodded suddenly, Xiao Tianxing took out a stainless steel long sword again and handed it to Tie Shan.

"Uncle Tieshan, how about you take a look at my steel sword?"

Taking the stainless steel long sword in Xiao Tianxing's hand and observing it, Tie Shan also nodded with satisfaction.

"Well, this steel longsword is not bad, it should have been forged about sixty-six thousand hammers. It should be worth more than five hundred gold coins, where did you buy this sword?"

"I didn't buy it, it's one of the ten steel swords that Uncle Your Majesty gave my father when my father and I first came to the fortress. ”

"Actually, I had a steel sword that was almost there, but it broke during the battle, so my dad gave me one. ”

"As for the stainless steel long sword that was broken just now, my father bought it for me in Liyang. ”

He said that it was enough to use this level of weapon in Liyang, and if the weapon was too good, it would be troublesome. ”

"Oh, I see!"

Returning the steel chief in his hand to Xiao Tianxing, Tie Shan continued his teaching.

"That's all there is to it about forging steel. Now let me talk about the water for quenching!"

"As you saw just now, when I was forging a weapon, I would quench it rhythmically. ”

"This quenching is on the one hand to increase the toughness of the weapon, and on the other hand, it is also to better forge the weapon. ”

"But the question of water for weapon quenching is a very important and critical factor. ”

"As you saw just now, our current quenching water is in an iron pass, but this is the best way to protect it. ”

"As for why this method is not good, it is because while the water in the iron pass is constantly quenched, the temperature of the water in the iron pass will gradually increase due to the red-hot metal. ”

"In that case, the quenching will become inconsistent, which will affect the quality of the entire weapon. ”

"The best way to quench is with water at a consistent temperature. So now I'm going to test you, what kind of water temperature is always the same?"

After lowering his head and thinking for a moment, Xiao Tianxing thought of an answer.

"Hmmm...?yes, the river. The temperature of the river water is ...... Wait, the temperature of the river doesn't seem to be the same!"

"In the morning, noon, and afternoon, the temperature of the river is different during the three periods!"

"If you take into account the weather and the seasons, the temperature of the river is even more different. ”
