Chapter 195: Bronze Sword Embryo
"Remove impurities! Master, what should I do?" Luo Yu asked.
"Master, here is a mortal material, bronze iron essence! You try to make a bronze sword with this piece of bronze iron essence, and now I will teach you to remove the impurities in it," said Hao Lao.
"Uh-huh"
"Forging weapons and casting swords, first preheat the melting furnace" Hao Lao said
Luo Yu nodded, the thunder flame beast fire rose in his hand, and he put his hand on the furnace wall. The thunder flame beast fire was absorbed into it by the red copper real fire furnace. The blessing turned into a raging fire in the furnace.
This is one of the functions of the melting furnace. It strengthens the flame of the fire controller, and saves effort when melting. However, Lao Hao's Nine Flames Li Furnace is self-contained and separated from the fire. He only needs to use his spiritual sense to control it when he refines it into an ordinary weapon. yes, very convenient
Preheating the melting furnace is to prevent the danger of frying the furnace due to sudden temperature rise.
After the Thunder Flame Beast Fire in the red copper true furnace burned for a while, Mr. Hao threw the bronze and iron essence into the middle of the melting furnace and said, "You first try to find the melting point of the bronze and iron essence, melt it and then keep it at a constant temperature."
"Oh, I see!"
Luo Yu nodded, using the mental method of swallowing flames to refine the body, controlling the temperature of the Thunder Flame Beast Fire by mobilizing the Thunder Flame Beast Fire in his body, the temperature of the Thunder Flame Beast Fire gradually increased, and the Thunder Flame Beast Fire in the melting furnace wrapped the bronze and iron essence, Burning.
The temperature inside the melting furnace is frighteningly high, reaching several thousand degrees, but there is only a faint heat outside the melting furnace, and the outer wall of the furnace is only slightly warm, not hot at all, and this is the second function of the melting furnace, heat insulation , these miraculous functions all come from the various inscriptions with unpredictable power.
The temperature in the furnace was getting higher and higher. Twenty minutes later, the bronze iron essence gradually began to melt, and after a while it completely melted into a liquid state, and Luo Yu also slowly lowered the temperature of the flame in the furnace to keep it at a constant temperature.
"Very good, now slowly raise the temperature. Remember, slowly raise the temperature. When you find that the impurities in it are burned and evaporated, keep that temperature. If the temperature rises, the Taicai bronze iron solution will be burned," said Hao Lao.
Luo Yu did as Hao Lao said, raising the temperature of the Thunder Flame Beast Fire bit by bit. When the temperature reached a certain level, there would be a trace of black smoke from the bronze iron essence solution, those were the bronze iron essence At this time, Luo Yu also kept the temperature control at this level.
Impurities in the bronze melt were burned and evaporated little by little, and the volume of the bronze melt was also gradually decreasing. After half an hour, the bronze and iron essence melted to one-third of its original volume in an instant. size.
"Almost, cool down, then turn off the flame, and the materials will be scrapped if you continue to smelt," Hao said.
Hearing this, Luo Yu slowly lowered the temperature of the flame, and then retracted the Thunder Flame Beast Fire. After the molten bronze cooled down again, it slowly solidified into an irregular piece of red iron.
Hao Lao waved his hand, and the bronze iron essence was taken out by a force.
"Yeah, that's right. Eighty percent of the impurities were removed in the first smelting. You really have the talent of a metalsmith," Mr. Hao praised with a smile.
"Hey, it's all master's good command." Luo Yu smiled, not daring to be proud.
"Okay, now start the second step, forging, since it is only forging a pure bronze sword, there is no need to smelt other materials."
Elder Hao took out a black forging iron platform, a forging hammer, and an iron clip. The hammer was not the amethyst hammer that Elder Hao used.
"You first fold and forge the bronze and iron essence continuously. When the number of folding and forging reaches a hundred times, the bronze and iron essence will reach the hardness level of a low-grade ordinary weapon," said Hao Lao.
Luo Yu nodded, clamped the red bronze iron essence and placed it on the forging table, held the material with the iron clamp in his left hand, and kept beating with the hammer in his right hand.
Boom boom boom boom boom!
After the bronze iron essence was flattened, it was folded into two layers and continued to be forged. The pounding sound was endless, reverberating in the training room, and Luo Yu kept beating, and his complexion gradually became sweaty. The caster was also a Physical work, Luo Yu's arms were already numb after beating for half an hour.
"Strike the iron while it's hot, don't stop, it will be even harder to forge after it's completely cold," said Old Hao.
Luo Yu gritted his teeth and forged for another half an hour, and finally folded and forged a hundred times.
"Okay, no need to fold and forge it, just beat it into a long strip, and then slowly forge it into a bronze sword."
Luo Yu picked up the forging hammer again and kept beating, and the group of bronze and iron essence was slowly forged into strips. Since it was the first forging, the long swords were shaped very irregularly, with width and narrowness. Thin and thick.
Luo Yu looked at the bronze sword that didn't look like a sword, and the ruler didn't look like a ruler, and he was a little speechless.
"Don't be discouraged, it's good enough to be able to do this for the first time forging. The remaining steps are to reheat and quench. For refurbishment, you only need to heat the sword until it turns red. When quenching, you must pay attention to the temperature of the water. For low-grade weapons, use water to quench them. The temperature of the sword cannot be too low, otherwise the material of the sword will not be able to withstand the temperature contrast and collapse, and what you need to focus on now is the forging technique. As a teacher, there is a set of hammering techniques, you can practice it yourself, and then use it for forging." Elder Hao said in relief, and then took out a scroll titled "Hammer Forging in Showy Rain" and threw it to Luo Yu.
"Understood, Master." Luo Yu took the scroll and nodded.
"Okay, I'll teach you the basics of refining weapons up to here, and you can figure out the rest slowly. I'll give you three more days as a teacher. After three days, I'll come and see the sword embryo you forged." Old Hao finished. I took Xiaolan and left
After Hao Lao left, Luo Yu opened the scroll, and the forging method of various weapons was recorded in the Shower Hammer Method. The weapons in the army are one inch long and one inch strong. All spears, spears, and Fang Tian's painted halberd are the most commonly used weapons. Luo Yu studied the forging method of swords carefully, and many things suddenly became clear. The two sides of the utensil are thin and the middle is thick, so the drop hammer is very particular. Where the force is heavy and where the hammer is light, you must pay attention to these, rather than hit it randomly.
"Look|x-on:正;version ☆C chapter + "section ¤ on P☆z
After looking at it for a long time, Luo Yu followed the method, put the bronze iron essence back into the furnace to heat it, took it out and continued forging.
The sound of thump, thump, thud, thud, has never stopped. The second time it was built is much better than the first time. It is not so irregular, but it still doesn't look like a sword. Luo Yu returned the bronze and iron essence to the furnace again and forged it again.
And the sword embryo that was reforged for the third time was much better than the previous two times, but Luo Yu was still dissatisfied.
Remelt, reforge, reforge, reforge...
This is because there is no such kind of genius in the world who can learn everything at once. The existence of such awesome characters is all blown out. There are only people who work hard like Luo Yu...
I don't know how many times it was reforged and reforged. Luo Yu held a three-foot-long bronze sword with a simple and majestic appearance. The hilt is just enough to be held with both hands, and the intersecting texture on it can prevent slipping very well.
"The bronze sword embryo has finally been forged..."
