Vol 2 Chapter 219: 0Summer iron

Five days later, the blacksmith camp.

Liu Yu's eyes were full of bloodshot eyes and his eyes were red, but he didn't see a trace of tiredness on his face. Now his entire face was roasted by the fire and it was dark. Only his red eyes remained on his face. , Still staring fiercely at the blue furnace and the iron furnace, the red knife-shaped steel block.

Kong Jing on one side was already shirtless and pulled the bellows on his side, while Mao Qiu held a few black coal in his hands, watching the fire in the furnace nervously, his hands shaking slightly. .

The sound of a "pit" burst, a piece of coal in the furnace burst, a few ignition stars burst out, and flew onto Liu Yu's body, a few light smoke suddenly appeared, and the color of the fire in the furnace also changed from red to green.

Liu Yu jumped up and shouted: "It is now, throw the graphite ball!"

A few briquettes in the hands of Mao Qiu were quickly thrown into the hearth, and they were suddenly engulfed by the blazing flames, and the fire color in the hearth became a pure blue, and the heat wave that could almost melt the person was coming. , It can just light everyone!

Liu Yu flew a foot, kicked the iron door of the furnace closed, and Kong Jing on one side, clenched his teeth and vigorously blasted at a speed that was at least two times faster than just now. As his movements suddenly accelerated, the entire blacksmith shop Just like the crater, the sweat on the human body just steamed and dried up.

Liu Yu said nothing, after kicking on the furnace door, he picked up a big hammer, Mao Qiu and Feng Qian picked up a pair of pliers, and tightly clamped the red piece on the furnace Steel block, but if you look closely, you can find that this whole knife-shaped steel bar is actually divided into two parts. The layer of the blade is about three or four inches thick, which is different from the material of the entire blade. Even the color that turns red after being heated is different.

Liu Yu picked up the sledgehammer and began to smash the two pieces of steel, and the hair ball turned the edge of the blade and lifted it to the center of the iron. Liu Yu ’s arm muscles followed his knocking. Strike, swell up a bit, after every few hits, it will let the hair ball continue to take this knife-shaped red steel back to the stove for heating, and vaguely, some black things can be seen from the edge of the blade Penetrating the blade and back of the blade, as fine as particles, and Feng Qian will also hold a small bag of charcoal powder, and from time to time follow the instructions of Liu Yu and Kong Jing, sprinkle a little bit on the back of the blade.

So, after repeatedly hammering more than seventy times, Kong Jing stopped the bellows in his hand and said in a deep voice, "It's almost done."

Liu Yu nodded, put down the hammer in his hand, stepped forward to take the big pliers in the hands of the ball, turned the whole piece into a knife-shaped steel, and dipped the large piece on the back of the knife into a bucket of grease on one side In the middle, just listening to the "zi" for a while, the light smoke rises, this barrel of fat begins to bubble, and the burnt smell of the barbecue fills the entire blacksmith shop.

But the big piece of the blade remains outside this barrel of grease, although the big piece on the back is slowly fading red, but the big piece left outside is still like melting, Liu Yu His hand is not moving, ensuring that the three-inch redness of the blade is not in the grease. It was not until one quarter of an hour before he lifted this piece of knife steel. I saw that the back had turned into a black and black color, and it was no longer hot. Three-inch cutting edge, still crimson, steaming.

Liu Yu directly put the part of the blade into the iron furnace again, Kong Jing ignited a fierce fire again, and after a few minutes of baking, the whole blade became red again, this time Liu Yu only smashed it slightly After a few clicks, the blade was immersed in another urine bucket beside it.

With a sigh, the whole blacksmith's shop was filled with a neutral taste, which made people feel like they were in a pit. Liu Yu's brows were wrinkled, which reminded him of the last time he assassinated the Diao family brothers. The experience of drilling the dung canal is so familiar. This time, in order to quench, the urine of the five livestock such as pigs, cattle, sheep, horses, donkeys, etc. was also taken deliberately.

Thinking about it, Liu Yu couldn't help but get out of his mind, until Kong Jing on the side said loudly: "It's okay!" He just reacted and took the knife steel out of the urine bucket. It can be clearly seen that the edge of the blade shows the color of bronze, with a faint glow of purple, and the back of the blade shows the color of black and black, which is the color of the wrought iron infiltrated with carbon powder.

Kong Jing rushed to the knife in one arrow, carefully examined the color of the knife body and the stripes on the knife, and kept nodding: "Okay, it's so good, I can't think of this Xianbei's sword-making method, It is so magical to use Baisteel as the blade and wrought iron as the back of the knife. When mixing and refining, the carbon powder in Baisteel can penetrate into the back of the knife to make the wrought iron hard and tough! "

Liu Yu smiled, holding big iron pliers, holding this blade, and facing a fine iron armor, he just waved hard and only heard a whizzing sound. The iron armor made in front of this knife, like a piece of tofu, should be divided into two halves by hand ~ EbookFREE.me ~ fell down to the ground from below the chest.

Kong Jing's eyes widened: "It's too powerful to think of using these five animals to drown and quench, there is such a magic weapon that really cuts iron like mud." And there was a burst of cheering in the blacksmith shop, Many craftsmen who had been busy for days and nights hugged together in excitement, and tears came out.

Liu Yu's eyes fell on the back of the knife: "Below my knife just now, the back of the knife does not have that kind of strenuous feeling, and the texture has not changed. From this perspective, this knife is above the battlefield and can cut such armor. At least twenty or thirty pay, enough to cope with the whole war! "

Kong Jing let out a breath: "Liu Yu, you are really a gift from Heaven to the Beifu soldiers. This knife is made by you, so you name it. There is also a mixture of steelmaking and wrought iron. The method of steelmaking is also named by you! "

Liu Yu smiled slightly: "The charcoal powder was infiltrated into the wrought iron by Bai Steelmaking, which is similar to pouring. This method of steel making is called steel pouring method. As for this knife?" He groaned a bit, "Bai Steel Making's The blade is placed on the body of the wrought iron knife, which is like a boarding. This knife is called the Bailiansu iron knife! "

Xie Xuan's voice came from outside the blacksmith's shop with his applause, and his figure, accompanied by more than ten guards, entered slowly.

Everyone's face changed, and they all knelt down. After a military salute, Liu Yu knelt on one knee, holding the knife in both hands, and dedicated it to Xie Xuan. , The kind of iron-cutting sword you want to build with a humble job, right here, please accept it! ") !!
