"Look at the boy, this refining tool has similarities and differences with alchemy. The similarity lies in the fact that alchemy requires various medicinal materials to be put into the Dan furnace in batches according to their pharmacology and different amounts, so that they can be fused into Dan. The same is true for refining weapons, which require the distribution and smelting of various metals with varying hardness and toughness according to the characteristics of the weapon before modeling. ”

In a separate refining room in the Daoyuan Palace, Ou Yezi stood at a long table and said to Chen Yuan, and all kinds of metals were placed on the long table behind him. Since Chen Yuan took out the design drawings of Fang Tian's painting halberd, Ou Yezi spent a full week in accordance with Chen Yuan's requirements for weapons, to test and mix the proportions between various metals, and today he can finally start smelting metals and officially start casting Fang Tian's painting halberd.

In the past few days, Chen Yuan has come to see the progress of the production of his weapons from time to time, and under Ou Yezi's intentional or unintentional **, Chen Yuan can be regarded as beginning to understand the refining weapon. Let's just say that the proportions between the metals,At first, Chen Yuan didn't understand it at all,In his impression,Making weapons is to make a mold,Then pour it with molten metal,And finally temper and polish it.。

However, Ou Yezi's production method was completely different from what he imagined, first of all, Ou Yezi asked Chen Yuan in detail about the requirements for this Fang Tian painting halberd, including weight, size, pattern and even color, and recorded it very carefully. He then spent a lot of time smelting the metal in small quantities and testing the strength of all aspects of the metal. This caused Chen Yuan to think that Ou Yezi was not seriously helping him refine weapons. It wasn't until one time, after listening to Ou Yezi's explanation, that Chen Yuan began to have a new understanding of the profession of refining.

In the Nine Heavens Domain, the status of the refiner is also very high, because of the high precision of this profession and the peculiar fusion and quenching technology, there is a certain chance that the inanimate weapon will be spiritual, which is the so-called spirit soldier. The existence of the spirit soldier is like an extension of the master's body, and the spirit soldier after recognizing the master, no matter how destructive or sharp, will not hurt his master. Moreover, the material fusion of spirit soldiers is more perfect than ordinary weapons, which also leads to the fact that spirit soldiers are stronger than ordinary weapons in terms of strength and toughness. It can be said that on the battlefield, the chances of survival of those who have spirit weapons will increase exponentially, so spirit soldiers are scarce everywhere they go, which has led to the rise of the status of the refiners who cast them.

If you want to become a refiner, you must first know how to design weapons, only a refiner who can design weapons suitable for different people can be regarded as a qualified refiner, no weapon of his own style, a caster who does not have his own ideas, will not be called a refiner, so when Chen Yuan took out the design of Fang Tian's halberd, Ou Yezi was so surprised, and then promised to let Chen Yuan watch his refining weapon is also moved by his love for talent.

Another threshold for becoming a refiner is to fuse metals, and if you want to fuse a good molten metal, you must know the characteristics of each metal well. Which metal can improve the flexibility of the weapon, which metal can increase the hardness of the weapon, which metal will make the weapon sharp, etc., and even the melting point of various metals, the rejection and conflict between metals, and what kind of changes will occur in the environment under which the characteristics of various metals will occur, this series of questions must be kept in mind, and according to their own needs, meticulously complete the distribution of metals, in order to be a qualified refiner.

These days, here in Ou Yezi, Chen Yuan has really learned a lot of knowledge about refining weapons, at least the metals placed behind Ou Yezi, he knows the names, and even knows their characteristics, and now, it is finally time to open the furnace for casting.

"Ah Xiang, pull the bellows, open the furnace!" Ou Yezi instructed a young man beside him. The young man next to him is no longer in the category of teenagers if he is a single round size, Chen Yuan, who is about to be thirteen years old, is already one of the top among his peers, but the young man standing next to Ou Yezi, although he is also in the fourteenth or fifteenth grade, has reached a terrifying height of one meter eight. It is only a little lower than Ou Yezi, and it is a head higher than Chen Yuan.

It looks a little fat, but the muscles on the arms are angular, and with the movements of the young man, they are constantly rising, and the unkempt black hair almost covers a pair of eyes, although the body is not like Mr. Bodybuilder, but it really interprets the word tiger back and bear waist, at first glance, it gives people a shocking sense of strength, but there is always a simple smile on the face, which is incompatible with the momentum embodied in the figure.

This young man is Chu Xiang, who is known as the "elephant idiot" in Feng Sanqi's intelligence, a young man born with divine powers, and also a close disciple of Ou Yezi. Chen Yuan has been in contact with Ou Yezi a few times, this big man who looks honest is surprisingly easy to get along with, although the body type seems relatively burly, but the personality is very intuitive on the face, honest and honest, and sometimes even some natural stupidity, but the strength is indeed not to be underestimated. No, under Ou Yezi's instructions, he walked to the bellows that occupied a third of the room, held the special bellows lever with both hands, and lifted the super-large bellows with a resistance of 10,000 catties.

Ou Yezi transferred a fire attribute spiritual power into a special furnace, igniting the fuel in the furnace, which was a fire attribute spirit crystal, and the temperature was as high as thousands of degrees after ignition, driven by the super wind power of the bellows, the furnace quickly became red, and then Ou Yezi began to throw metal into the furnace in an orderly manner.

"Thousand Star Iron, the Forging Dragon Rock has a low melting point, and it is the most inclusive, and it is the first to enter the furnace. After thirty-five breaths, add purple moon copper to fuse to strengthen the hardness of the metal, and after eighty breaths, add killing stones to increase the sharpness of the metal······" Ou Yezi started to add metal to the furnace while chattering, and always paid attention to the progress of the melting and fusion of the metal in the furnace.

"Pour the furnace!" After adding the semi-metal material, Ou Yezi let out a loud shout, pushed out with a palm, and imprinted it on the huge furnace, the furnace tilted, and the fused metal liquid flowed into the mold prepared in advance.

"Ah Xiang, the maximum wind!" Ou Yezi shouted, and another strong fire attribute spiritual power rushed into the furnace, and the fire spirit crystal embedded in the furnace suddenly turned purple, and the temperature rose one step again.

Chu Xiang pulled the bellows hard, Ou Yezi began to put metal into the furnace again, but this time the speed was much faster, in just thirty-six breaths of time, the remaining half of the metal had all entered the furnace, and after another ten breaths or so, Ou Yezi was a palm again, and the remaining metal liquid also smoothly entered the mold.

In the past, half of the metal was used to create the halberd head, so the metal and fusion methods used were all aimed at the necessary properties such as hardness and sharpness. Later, the metal was used to pour the halberd, so the choice of materials and techniques was more inclined to toughness. The most ingenious thing is that although it is cast in two parts, in a mold, the metal liquid is injected twice, and the time can be controlled, so that the two metal liquids are combined together before solidifying, and the characteristics of each other are not affected.

When the liquid metal completely fills the mold, the other half of the mold is also covered with a bang, and after sealing the mold with spiritual power, the next step is quenching. Of course, the lower the temperature of the quenched water, the better, for this reason, Chen Yuan also specially invited Ning Wuru to come and inject the aura of ice attribute into the water in the pool. Ou Yezi threw the mold into the pool prepared in advance, and the cold air in the pool was urgent, and it was the pool water that Ning ruthlessly injected with ice attribute aura.

"Zla!" A large amount of water vapor rose, and the mold made of rock cracked under the two extreme temperatures of hot and cold, and after three seconds, Ou Yezi fished out the mold, put it on the casting table, stepped on the bellows, and started a fire with the wind, igniting the furnace under the casting table.

I saw Ou Yezi tear off his shirt, revealing his extremely strong upper body, picked up the half-human-high casting hammer, and slammed it on the mold. With a "bang", the mold shattered, revealing the rough embryo of the Fang Tian painting halberd that had solidified. The dense sound of "clanging" came from the top of the casting table, and Ou Yezi wielded the casting hammer, knocking on the rough embryo on the casting table like a whirlwind.

Under Ou Yezi's continuous knocking, the original surface of the potholes, the dull luster of the Fang Tian Painting Halberd Rough Embryo seemed to be transforming little by little, the black and rust-like stains on the surface were slowly fading, and the potholes and bumps began to become traceable and regular.

"Dangdang Dang!" As the sound of Ou Yezi's knocking became louder and louder, the force became heavier and heavier, and in addition, there was continuous heat coming from below, and a large number of impurities began to be blasted out of the rough embryo on the casting table one by one, and these impurities continued to fly in all directions, and the heat contained in it was still powerful, so that Chen Yuan couldn't help but take a few steps back and avoid it. Under Ou Yezi's beating and hammering, the original rough embryo has shrunk by nearly one-fifth, but the color is getting clearer and clearer, and the luster is becoming more and more dazzling.

"When!" Ou Yezi's last hammer fell, and the entire Fang Tian Painting Halberd appeared with a hum, and suddenly suspended in mid-air, and a domineering charm and wild power erupted in an instant. "Not good!" Ou Yezi shouted, stretched out the spiritual power shield, protected Chen Yuan and Chu Xiang, and said secretly: "What a domineering weapon, it has just become a spirit, and it has such momentum. ”

But too rigid and easy to break is the eternal truth, after the formation of the spirit soldier, if you do not take the initiative to restrain your momentum for the first time, it will incur heavenly punishment, after all, the weapon has a spirit is a thing against the sky, the law of heaven and earth does not allow such a thing to happen, once you don't know how to converge, there is only one end, that is, under the agitation of the power of heaven and earth, it will become a cloud of debris. This Fang Tian painted halberd into a spirit, his strength was domineering and powerful, and it seemed that it was impossible to take the initiative to converge, so Ou Yezi had to sigh secretly and sigh a pity, and pulled Chen Yuan and Chu Xiang to hide away.

"Wait. Chen Yuan looked at Fang Tian's painting halberd suspended on the casting table and said. At this time, the power of heaven and earth had begun to converge, and a small tangible vortex slowly formed directly above Fang Tian's painting halberd, and it increased little by little, pressing down inch by inch.

The halberd floating in the air was forced to fall little by little, but still did not give in, and the tail of the "ding" halberd was embedded in the casting table, and under the huge pressure of the power of heaven and earth, the halberd body also began to make a tooth-aching creak.

"Let's go! In a moment, the halberd will explode into iron filings in the sky, and if you get closer, it will be shot into a sieve!" Ou Yezi said to Chen Yuan with some anxiety. This is Chen Yuan moved, he gritted his teeth, cut his palm, and a series of blood flew towards the Fang Tian Painting Halberd, which was already somewhat bent under the power of heaven and earth.

"Zheng!" A crisp buzz sounded, stained with Chen Yuan's blood on the Fang Tian painting halberd, a blood light lit up, some curved halberd body suddenly became straight, but the breathtaking momentum disappeared, the power of heaven and earth had no goal for a while, slowly dispersed, Chen Yuan beckoned, the Fang Tian painting halberd inserted on the casting table buzzed, turned into a rainbow light and flew to Chen Yuan's hand, the painting halberd started, a feeling of blood connection spontaneously appeared, Chen Yuan pulled up the painting halberd and played a few moves, nodded with satisfaction.
