There is a huge casting furnace in the casting room, the monk's weapon is different from the ordinary people's mortal weapons, and the casting method is also different from it, the biggest difference is that the monk needs to inject yuan force into the weapon to cast weapons, and build a complete set of yuan force flow patterns in the weapon, and when the monk uses the weapon, he can inject his own yuan force into the yuan force pattern of the weapon, so as to enhance the power of the weapon. The quality of weapon casting depends greatly on the quality of the Yuanli pattern. Moreover, when using the casting furnace, it will also consume the monk's yuan power, and the casting fire in the casting furnace needs the monk to ignite it with the yuan force. Without the support of a strong Yuan Force, it is impossible to forge a powerful weapon. Therefore, a great foundry must also be a powerful monk.

Xia Yu immediately followed the casting method he had learned in books before, first lit the furnace fire with Yuan Li, and then poured a bag of thirty catties of refined iron into the casting furnace in one go, Yuan Li increased the flames, and with a bang, a huge flame burst out of the furnace, and the whole room was suddenly reflected red.

Xia Yu used Yuan Force to hold up the fine iron, allowing them to slowly spin in the flames. Under the raging fire, after a while, these refined irons turned into a ball of molten iron, wrapped in Xia Yuyuan's power, and swirled and floated above the flames in the casting furnace. At this time, Xia Yu suddenly noticed something, he found that thirty catties of refined iron seemed to be a bit too much for forging swords, after a little thought, Xia Yu understood, presumably the disciple of the Immortal Weapon Pavilion found out that he was a novice, so he had evil thoughts and slaughtered himself fiercely. Xia Yu sighed helplessly, and didn't bother to bother with him, anyway, he couldn't succeed at one time, and these thirty catties of fine iron might not be enough for him to spoil it.

Xia Yu immediately split a large ball of molten iron into two, leaving only a small ball of molten iron enough to forge a sword, and the other large ball took out the casting furnace and poured it into a professional container on the side, and then Xia Yu began to concentrate on pondering the small ball of molten iron left in the casting furnace.

First of all, the first step of sword casting, sword casting. In this step, the molten iron is compressed into the shape of a sword with Yuan Force. In this step, the ability to control the power of the yuan force is extremely demanding, and the sword shape is not only the appearance of a sword, but also determines the inside of the sword. There are some extremely sharp swords, even if they don't inject Yuan Force into the sword, they can still cut iron like mud, blow hair and break hair, which is a good step of sword casting. Moreover, for monks, although Yuan Li is a part of their own strength, it is difficult to be as flexible as human hands in actual use, and it is also a difficult challenge for ordinary monks to use inflexible Yuan Force to create the shape of a sword, especially the blade, tip of the sword, or carved patterns on the body of the sword.

In this first step, Xia Yu made a difficulty. Molten iron is liquid, and you can imagine how difficult it is to keep a lump of liquid in a fixed shape. Xia Yu first roughly pinched the molten iron into the shape of a sword, this step is not difficult, ordinary monks can do it, it is rare to see the details later. After Xia Yu pinched the tip of the sword, he was about to pinch the blade, but the tip of the sword was broken; after pinching the blade, he was about to pinch the hilt, but the blade was broken again; he finally pinched the hilt of the sword, and just wanted to pinch the tip of the sword again, but the sword shape of the whole sword was broken. In short, Xia Yu has been busy for a long time, and the basic shape of the interpreter has not yet been pinched out.

The step of forging the sword type is the most test of a monk's ability to control the Yuan Force, and the most difficult aspects of this step are two points: shaping and maintaining. First of all, you have to use the Yuan Force to shape the sword in your heart, and you have to keep it. Otherwise, it will be like the summer rain, the black blind man breaks the bud rice, breaks an ear and throws an ear, and cares about the east and the west.

However, Xia Yu is casting a sword for the first time, and he is still not proficient in skills, which is understandable. Even the famous sword-casting immortal master Yun Wanli, I heard that when he first learned to forge a sword, he was scolded by the master for being bloody. He was originally a disciple of the Immortal Weapon Pavilion, but he was kicked out of the portal by the Immortal Weapon Pavilion because he had no talent. At that time, this matter was a big joke that everyone knew, because there had never been a disciple who had been expelled from the Immortal Weapon Pavilion because he was too stupid, and everyone pointed fingers at Yun Wanli and called him a waste behind his back. But Yun Wanli did not give up, and still persevered in studying the way of forging swords. As a result, ten years later, the five ancestors of the Immortal Artifact Pavilion collectively knelt at the door of Yun Wanli's house for ten days and ten nights, wanting to invite this former disciple of the Immortal Artifact Pavilion to return to the Immortal Pavilion to take charge of the pavilion master, but Yun Wanli was also stubborn, and the birds didn't bird them, so he only gave them a word.

The version circulating in the market is more literary: I knew this was the case, why bother in the first place?

But according to Yun Wanli's good friend, in fact, this is the real version: his grandmother's, now that he knows that he has come to ask for a master, what did he do earlier?

However, Yun Wanli is also an immortal, and in order to maintain his beautiful image in the hearts of mortals, proper processing is normal.

Therefore, talent is of course very important, but having a persevering heart is actually the foundation of great things. And it just so happens that Xia Yu is such a man who admits death.

Xia Yu continued to forge the sword shape, and the repeated failures would not make him lose confidence, but would only give him more powerful motivation. The raging flames in the casting furnace roasted Xia Yu's face red, he felt that his face was about to burn, his body was even more sweaty, and most of the yuan power was consumed, and the continuous high output yuan force and high-intensity mental concentration were tormenting Xia Yu, but Xia Yu did not dare to relax a little, and the yuan power was still continuously input into the casting furnace. In the end, the molten iron finally took on the appearance of an interpreter under his hands, and Xia Yu had to take the next step.

There is also a certain law of sword casting, and when the time comes, whether the sword casting is completed or not, it has to be the next step, otherwise the sword will be completely scrapped, and there will be no chance of baking.

The second step of forging a sword is forging a sword vein. Just as there are seven meridians and eight veins in the human body, there are also Yuan Li veins in the body of the sword, which are called sword veins. The quality of the sword vein directly determines the strength of a sword. Those world-famous immortal swords all possess tens of millions of sword veins, like Xia Xue's Biluo Huangquan Sword, there are 37 million sword veins. There are many types of sword veins, and the sword veins on the market are basically divided into three categories: fish bone veins, ice crack veins, and tree veins. These are the three most basic sword veins, and the swords used by ordinary monks are basically these three sword veins. In addition, there are some more advanced and very difficult to forge sword veins, and the sword veins of fairy swords are different, and the sword veins of each of the ten immortal swords are different, all have their own characteristics, and they cannot be imitated. And the interpreter's sword vein is different from any kind of sword vein in this world, it is a new kind of sword vein.

There are some similarities between sword casting and carving, the difference is that the carving is on the outside of the object, while the sword casting vein is on the inside of the sword, the carving uses a carving knife, and the sword vein casting uses Yuan Li.

Xia Yu held the sword in the casting furnace in his hand, closed his eyes, and his mind immediately invaded the inside of the sword, using his mind as the way and the yuan force as the tool, and began to open mountains and seas in the sword, casting sword veins. The interpreter's sword vein was already imprinted in Xia Yu's mind, and he cast the sword vein without the slightest hesitation, and the vast Yuan Force swept through the sword like a storm, and a new set of sword veins was imprinted in the sword. It's just that casting sword veins is actually a careful job, Xia Yu seems to be fast and chic in one go, but this set of sword veins also makes his casting messy. Moreover, casting the sword vein requires a lot of yuan power, Xia Yu just spent too much yuan power in the process of casting the sword type, but at this time, there is some lack of follow-up, so the sword vein casting is too shallow. But at this moment, the sword vein has been completed, and if you want to change it, you can't change it, so you can only enter the third step.

The third step is tempering. This step is much simpler than the first two steps, but it is also very important, that is, the sword that has been shaped is constantly tempered in the fire, the most important thing in this step is the heat, if the fire is not well mastered, the first qiē will be all in vain. The casting fire needs yuan force as fuel, but after Xia Yu passed the first two levels, there was not much yuan force left in the body, and the yuan force input into the casting furnace began to become intermittent, and the flame in the casting furnace became smaller and smaller, and finally Xia Yu finally couldn't support it, so he could only finally release a trace of yuan force and open the furnace to take the sword.
