"The art of forging a sword is roughly divided into three steps - embryo making, smelting, forging and quenching. Pen Fun Pavilion www.biquge.info"

Jiao Zhan Langlang said, "Embryo making is to make the embryo of the sword cast, only some disciples of the inner gate who have learned the art of spells can make embryo molds, and if the ordinary disciples of our Sword Casting Palace want to make any sword, they can only go to Zongmenfang City to buy it." ”

All the disciples nodded again and again, and Fang Yun was also moved in his heart, and wrote down the four words "Zongmenfang City".

"This is the flying sword embryo I prepared in advance. Jiao Zan took out a box from his arms, opened it carefully, and took out a scabbard-like mold, which was engraved with some cloud-like patterns, just by looking at it, he felt dizzy.

Fang Yun didn't dare to look at it more, and said in his heart: "So this is the mold of the sword?"

"Next, I will demonstrate smelting, forging and quenching, this is the main skill you will master in the future, and you will need to use these skills for the fine iron that will be handed in every month in the future, look at it!"

He stretched out his iron tongs, went to the material pool on the side to pick out the ore, and threw it into the crucible in his right hand, "Smelting is to melt the main materials of sword casting together, and the main material of our sword casting is fine iron, that is, the pig iron containing impurities is turned into after repeated forging and removing impurities."

As for a small amount of other materials, such as tin, manganese and other materials, they should be added strictly according to the formula of flying sword casting, and should not be increased or decreased at will, otherwise the quality of the cast flying sword will be poor and it will become a waste product!

As the saying goes, three years of iron, ten years of sword casting, that is, the importance of experience accumulation of sword casting, the more diligent and hard work, the more you can deeply understand the mystery of sword casting, no worse than the mystery of martial arts!"

As he spoke, he showed the various materials sandwiched into the crucible to the miscellaneous servants, and Fang Yun saw that most of it was a kind of inky black ore, about three fist-sized pieces, which should be pig iron, and a small amount of it was some colorful ore slag, which was supposed to be the tin, manganese and other things mentioned by Jiao Zhan.

I saw Jiao Zan take out a command flag and hit a spiritual light on the crucible, and the surroundings of the crucible suddenly shone slightly, and the fine and complex patterns lit up, explaining: "The temperature of the fire of the lungs is too high, if there is no protection, it can melt both the ore and the crucible, so it must be protected by formation." We have a lot of these cauldrons in the Sword Casting Palace, and it takes time to apply for the steward. ”

The disciples nodded again and again, and Fang Yun also secretly wrote it down, thinking that this is the immortal casting technique, which is very different from the iron-striking technique taught by the master before, the furnace temperature of mortal iron-striking cannot be so high, as long as the crucible of ordinary graphite is prepared, the master should also be an immortal cultivator, maybe he deliberately concealed the immortal casting technique, and only taught himself the ordinary casting technique, right?

As he thought about it, Jiao Zan had already stretched the crucible into the crimson blazing fire, and the four handymen next to him stepped up their tugging bellows, and with the whirring flames, the ore in the crucible gradually melted, gradually turning into a puddle of dark red liquid with flames.

Jiao Zhan's eyes were blazing, and he focused all his energy on this small puddle of liquid, and his right hand took out a handful of sand from his bosom, and sprinkled it into it, and suddenly a green flame rose, and the liquid in the crucible gradually turned bright red, as if many impurities in it had been removed.

"This is the dust and sand, which is configured by the master of the inner door, which can burn away some of the impurities in the ore, so that the melted liquid becomes soft and clear, ready for the next forging. ”

Casually explaining, he took the crucible out of the oven, hung it in the air for a while, and waited until the melted liquid began to slowly solidify, then poured it into the flying sword embryo prepared on the side, and suddenly snorted green smoke, and the metal liquid was in a semi-solidified state, like a puddle of wax and oil.

At this time, all kinds of mystical lights and shadows rose from the sword embryo, making Fang Yun have an illusion, as if he saw a pair of big hands kneading this mass of metal liquid, kneading some kind of mystical heaven and earth rules into it, thinking that this was the role of the formation pre-engraved in the sword embryo.

After another moment, when the light and shadow gradually subsided, and the liquid also became solidified, Jiao Zan used pliers to clamp the sword embryo onto the cutting board on the side, and then picked up the hammer and slammed it, smashing the embryo mold into pieces, startling the surrounding miscellaneous servants.

"This embryo mold can only be used once, since it has been used in this sword casting, it will naturally become a waste, and it is useless to leave it!"

He said coldly, then picked up the hammer and began to forge the sword embryo in ping-pong, further removing the impurities in it and making the materials inside more tightly fused.

"You see, there are 36 kinds of forging techniques - knocking, grinding, spinning, drilling, picking, dragging ......"

Ping Pong!Ping Pong!

With his demonstration, thirty-six techniques were presented one by one, and others were dazzled by the fact that they remembered the previous technique, and did not care to write down the next one, or memorized the next one and forgot the previous one.

However, in Fang Yun's eyes, he didn't feel that there was much mystery, although it was much more subtle than the technique taught by the master, but compared to the one hundred and eight hammer method of the mysterious master, it was as immature as a child.

Many other miscellaneous servants could not see the subtle subtleties, but they did not escape his eyes, and then confirmed with the skills of the master and the mysterious man, he suddenly understood a lot, and the corners of his mouth couldn't help but curl slightly, and his heart was happy.

"It turns out that the word 'grinding' should be used here!"

"Huh, this 'pick' word trick is still so wonderful, wonderful, wonderful!"

He saw that his eyebrows were fluttering, and he nodded again and again, but he fell into the eyes of the two brothers Song Cheng and Song Shan on the side, they were at a loss for these techniques, and they couldn't understand them at all!

At this time, seeing Fang Yun's overjoyed appearance, he was all angry, and scolded in his heart: "Fuck, this dumb man knows a fart? Lao Tzu can't even understand it, and he is really able to pretend to shake his head! I have to find a chance to tear down his mask later, and let the master see the face of this bearded and slapping horse villain, hum!"

Fang Yun didn't know that these two villains were slandering themselves on the side, he had already focused all his energy on Jiao Zhan's iron-striking skills, looking at it, he sincerely admired: "Although Master Jiao Zhan's iron-making skills are not as good as the big man, his overall situation and control are refreshing, and they are really useful to me at this stage!"

For example, Jiao Zan will first forge the sword embryo as a whole to make the impurities in the sword embryo float to the surface, and the technique used is soft; then violently tap one place to concentrate on removing the impurities inside; then use grinding, rotation and other techniques to massage the sword embryo, as if to loosen the muscles and bones, and then repeat the previous steps; when encountering impurities that are particularly difficult to remove, he will use drilling, picking and other techniques.

Although he is still far from the master of the unity of heaven and man, it seems that half a foot has already stepped in, and forging is like an art in his hands, not just a skill.

Fang Yun couldn't help but sigh secretly, when would he be able to reach such a level?
