However, if the Ice Crystal is not forged, the soul inside will soon die due to fear of the cold. However, ordinary magicians can't master such forging techniques, so the ice crystal is basically a lost magic in the earthly world.

Dusty gradually hammered the crystal into a flat shape, and Ilt cooperated with the rest of the spring water and put it in a 'stone bucket' with a recess in the middle.

"In this way, a simple forge has been built."

Ilt spread his hands as if he were already in the forge yard. Dusty lifted the crystal with pliers and plunged it into the sink in one go. Before this moment, the crystal had just been heated to a temperature of several hundred degrees on the hot stone platform, and immediately bubbled violently after encountering the slightly cold spring water at room temperature. At the sound of rubbing, the water boiled, and the bursting blisters and water vapor stirred on the surface of the water. The crystal cooled rapidly in the water, and the hot, red surface gradually returned to its transparent color.

This state lasted for tens of seconds.

Dasti grabbed the end of the crystal with iron tongs and placed it on the stone platform to continue to strike, and the shape of the crystal gradually became more elongated.

"Wouldn't it be easy for the Ice Crystal to shatter when it was cooled down again?"

Alan asked.

"It's up to Dasty's technique. If it's such an easy thing, then where in this world is her turn to be a master. Now that she can be reforged, she may be the only one on this continent. ”

Ilt couldn't help but smile as he looked at Dusty's concentration on his face.

Dusty dipped the beaten crystal into the water again, and once again pulled it out, revealing a short dagger without a hilt, with a pure blade and a stem still exposed. Dusty raised the dagger above his head.

The dagger has a gentle arc from the root to the tip, and the whole body is transparent, and there is a wavy pattern along the surface of the dagger's blade, and if you look closely, you can see that there is a texture similar to a spell on it, but it cannot be read through, because the spell is engraved into the blade, and it seems to be a reflection in the opposite direction.

"How?"

"Is this the key?"

"Yes, this is the key to the Sacrificial Box created from Orion's soul. It's not all done, but if you get it done this way, the fire is a success. ”

Tempering is the process of forging the material used to forge the sword at an ultra-high temperature, and after it has cooled, it can be forged again. Burning can easily break the material, but it is the fastest and most effective method of forging.

Dusty knelt on one knee, clamped the dagger horizontally to the stone platform in front of him with his iron tongs, and began to strike with a small short hammer with greater precision. Knock for a while, knock for a while, keep repeating. From time to time, small sparks burst out of the blade and steam hot. Long white hair sticks to his forehead under the influence of moisture. Looking at it this way, Dusty's little face actually has a hint of a mature woman's taste, which is exceptionally beautiful and moving.

――If you have a better personality, this guy is really a good friend.

Ilte's inner monologue was unheard by no one else, but the moment Dusty raised his eyes to look at him, he unconsciously avoided it.

――What are you doing? Why should I hide from me, I don't have any other thoughts, absolutely not!

The self-comforting Ilt shook his head wildly, as if he was about to shake himself out.

"It's so hot."

The heat that filled the mine made Tia frown, forging in such a closed environment, let alone Dusty, even Tia, who was furthest away from her, was almost too hot to stand it.

"There's no bellows here, so you can't forge it over an open flame, it's stuffy, right?"

Dusty was already soaked with sweat, but she was smiling and seemed to be obsessed with the work at hand. She sat in front of the stone platform, holding a crystal dagger and looking left and right, and constantly beating, as if she was adjusting the shape of the dagger.

"In my hometown, I basically use casting molds to forge swords. The method is simple, that is, the molten iron paste is poured into the casting mold to produce the same style of sword in batches. There are very few swordsmiths like Dusty who forge swords. Most of the swords popular on the mainland now have straight blades and have no features at all. ”

Eren thought of his old friend, and wondered if Parker was still forging his own sword.

"The production of a large number of weapons at one time is to meet the needs of the present era. The answer to the question of personality or destiny is so simple that people will not answer it anymore. I'd rather forge each sword one by one. This technique is about to disappear in this continent full of batch forging, and some swordsmiths who originally insisted on it have to abandon their craft in order to make a living. ”

Dusty feels a little sad when he talks about swordsmithing.

"I know a man who, though not yet a well-known swordsmith, is one of the few swordsmiths who insists on forging his own swords. Dusty, I will definitely introduce him to you if I have the chance, and I am sure he will want to meet you too. ”

Alan was talking about his childhood friend, Parker, the boy he had made an appointment with.

"Well, I'm sure he'll be impressed by the swordsmith's profession."

Dusty said with a smile,

"The initial forging has been completed, and this process is actually not complicated, which is to repeatedly forge the crystal into hundreds of layers, make a crystal core, and the crystal shell, and then put it together and extend it through forging. The blade of the dagger is formed by cutting the extended end diagonally. Then hit the edge of the knife and beat it with a hammer dipped in water to remove impurities. But this crystal is so pure that I skipped this process. Finally, the surface is corrected with a grinding stone or file to create a wavy knife pattern. As for the spell inside, it was a seal set by Orion himself. Overall, the 'key' is complete. ”

Dusty talks endlessly about the process of forging, and only those who truly love this profession will work with joy under such difficult conditions. In the eyes of Allen, in the eyes of all, such a Dasty is lovely and selfless.

Although a large part of the people couldn't keep up with Dusty's professional terms, their eyes widened in surprise, as if to say, how many steps it takes to forge a small dagger!

"Rapid cooling when heated to the highest temperature is also the key to making a good weapon."

Dusty pointed to the stone bucket that Ilter had brought up, the water in which the water had cooled again. (To be continued.) )
