After passing the level of the introduction to refining, Puyun decided to teach the art of smelting. Pu Yun told Ling Feng that smelting was actually the real first step in refining a weapon. This involves putting all the refining materials into a furnace for melting, waiting until it is completely liquid, and then introducing it into a mold to cool. After that, it began to be tempered repeatedly, and finally the prototype of the weapon was formed. After that, it is put into the furnace for the final tempering, waiting for the weapon to be completely born.

Of course, because some materials need to remove impurities before being put into the furnace, the process of joining is to remove impurities, smelt, temper, form, and smelt. Of course, none of them have their own characteristics and know-how. The most important thing for a good alchemist is to have control over the materials, to be able to smelt them completely and fully. Of course, tempering before molding is also important. There is also the control of the heat during tempering. Too high will turn back into liquid, too low will not have the desired effect.

Pu Yun also told Ling Feng that if he wanted to carve runes in the mist, it was best to go between tempering and forming. When it is tempered, it will be able to make the runes completely part of the weapon. This is why there is such a process as refining.

The reason why the weapons refined by the Pu family's refiners are generally of better quality than other refiners is because they have been instilled in the importance of removing impurities, smelting, tempering and refining since childhood. Therefore, every step of the Pu family's refining will be taken seriously.

Now I'm going to tell you the trick of smelting. "The first thing to do is to raise the temperature of the furnace to the temperature I specified, and then put all the materials into the furnace and wait for them to melt slowly. Once the belt has completely melted, do not introduce the melt into the mold immediately. Instead, they should be left in high temperatures for a little longer, so that some of the liquid does not cool down as soon as they come out, causing molding failures. And doing so also helps with the carving of runes. When the mold is fully filled, it is time to start tempering. Okay, you can try it first. When you can do this well, I will tell you about the next refining."

So Ling Feng obeyed Pu Yun's arrangement and prepared to start the smelting work. First, Ling Feng began to raise the temperature of the furnace. Because the temperature of the ordinary flame was too slow, Ling Feng summoned the Samadhi True Fire, although it was only a little, but when it was placed under the furnace, Wen Di began to rise sharply. When Ling Feng summoned the True Fire, Pu Yun was also startled, because he had never seen a flame of this temperature before, and he began to look at Ling Feng again.

When Ling Feng raised the temperature to a certain level, Pu Yun said, "Okay, okay, you can feel this temperature first, so that you can control the temperature in the future" After speaking, Ling Feng began to feel the temperature in the furnace at this moment. Ling Feng felt that this temperature could literally melt him. Slowly, Ling Feng became familiar with this temperature. Xiang Puyun said, "Okay, master, I'm already familiar with it," Puyun heard this, so he casually extinguished the fire and said, "When the furnace is cooled, you can raise the temperature back for me." After saying that, Pu Yun walked back to the room with his back hand.

At this time, Ling Feng began to wait for the furnace to cool down completely. After about half an hour, the furnace finally cooled down. Ling Feng began to raise the temperature of the furnace again. This time, Ling Feng relied on the temperature he had felt before. After hitting the temperature increase to a certain extent, he stopped, and informed Puyun to test.

Pu Yun nodded in approval after the inspection. He said, "Well, it seems that you should be proficient in this step. Let's move on to the next step. First of all, you put the Adamantite Iron that you have previously tempered into a furnace and smelt it." Following Pu Yun's guidance, Ling Feng put the Pure Gold Iron into the furnace and began to melt.

During this process, Ling Feng needs to keep the temperature of the furnace from dropping, so it can be regarded as a test for Ling Feng. Finally, after half an hour of continuous smelting, the pure gold iron had completely turned into liquid, and Ling Feng knew that he still needed to go through it many times, so he didn't rush to draw out the melted liquid. A moment later, under Pu Yun's guidance, Ling Feng introduced the melted liquid into the mold that had been prepared in advance. Then Ling Feng was ready to start the tempering process. Because Ling Feng didn't know how to carve runes, Pu Yun only explained to Ling Feng when he should carve runes.

When the weapon in the mold was fully formed, Pu Yun prompted Ling Feng to quickly take it out for tempering, so Ling Feng quickly put it on the tempering table and began to temper it. In the process of Ling Feng's tempering, Pu Yun kept telling him not to be too strong and not too small, and in this way, under Pu Yun's guidance, Ling Feng began a long tempering process.

By the time it got dark, the weapons had already begun to turn golden. So under Pu Yun's guidance, Ling Feng stopped tempering. Put it in the heated furnace again. At this time, Pu Yun said, "Ling Feng, hurry up and feel the temperature of the furnace at this moment, remember to keep it in mind." Then you can hold this temperature and wait for the weapon to come out. Also, when the tempering is almost complete, you have to set aside a bit of heart to raise the furnace that has cooled, and remember to raise it to this temperature. And then it continues". After saying that, Ling Feng took over the job of maintaining the temperature from Pu Yun's hands.

After another night of tempering, the next morning, a sword was taken out of the furnace by Ling Feng and handed over to Pu Yun for inspection. After reading it, Pu Yun said, "Well, you can also refine it for the first time and practice it into a Xuan-level Pure Gold Sword, which is not bad." It seems that you have basically mastered the technique of refining. Let's take a break. After that, I will explain to you the refining manual and experience of the ancestor of Puyuan. ”

The next day, Ling Feng arrived at Pu Yun's residence on time. Pu Yun began to explain his understanding to Ling Feng, "First of all, the refining process I taught you before was derived by me by combining my own experience and the Ancestor's refining manual. Secondly, you need to know that the Refining Handbook contains a lot of information about the properties and utility of refining materials. It will help you to see materials you don't know in the future, and you can learn from them. Of course, the most important thing is the ancestors' refining experience. It records the experience of the ancestors who failed to refine successfully for the first time, and then succeeded in refining. It can be said to be a valuable experience for refiners. In the future, wherever you go, if you encounter something you don't understand, you should read more about these precious treasures. That's all I can help you with. You'll need to refine it yourself from tomorrow, and I won't be there to help you anymore. It's not complete until you're able to refine a ground-level weapon." After saying that, he drove Ling Feng out of the room.

After Ling Feng came out, he took a long breath. I know that from today onwards, I will be regarded as a refiner. Thinking about it began to rise with emotions of longing, it had been five months since Ling Feng had come here, and Ling Feng looked at the sky and began to miss Lei Yi'er and his father who were far away. Unconsciously fell into the memory.

It wasn't until Mu Lianhua came over to remind Ling Feng that he woke up from his memories. Then I heard Mu Lianhua say, "Ling Feng, why are you in a daze, the sky has already turned dark, why don't you go back." So the two went back to their residence together.

The next day, Ling Feng woke up and stretched out. At this time, he had slept soundest in recent times. After waking up and eating, Ling Feng decided to refine a ground-level weapon. Arriving at the furnace, Ling Feng thought to himself what kind of weapon he should refine. Suddenly, Ling Feng thought that Bai Li was still using a broken weapon, so Ling Feng decided to refine a battle axe and give it to Bai Li. As soon as he said it, Ling Feng took out the materials needed to refine the battle axe from the Qiankun Ring, and was ready to start.
