In addition to the refining of its own materials and the construction of the magic circle, the conversion between energies is also a very important part.

"Once you understand the law of conservation of energy, all that's left is how to choose the materials and make them hold more energy, and finally use them to make what you want. In fact, for Lingbao, appearance is the least important, and how to achieve the goal you want is the first priority. Feng Tianjiao saw that Zhu Yi quickly understood what he meant, and nodded with satisfaction.

"Then what should I do now?" Zhu Yi's gaze swept over the table in front of him, and there was a hint of eagerness in his eyes.

"It's very simple, think about what you want to do first, and then choose the materials you need, here are the various refining seals I have collected over the years, which can achieve different functions, and now the most suitable method for you is to pick a ready-made one to try, and when you can understand the meaning of these engravings in the future, you can also create your own engravings, at that time, your refining tools are unique, with a logo that only belongs to you!"

Feng Tianjiao threw a thick ancient book on the table, Zhu Yi picked it up and flipped through it, and found that there were many notes on it, which should have been left by Feng Tianjiao when he was studying before.

"Your task in the next few days is to read this encyclopedia of engravings first, and you can also try to reproduce some engravings, these gadgets look easy, but it is not easy to portray. Feng Tianjiao said to Zhu Yi.

Zhu Yi has also discovered that if he wants to read the engraving in this ancient book, I am afraid it will take a lot of effort, so in the next few days, Zhu Yi will also obediently study the engraving in Feng Tianjiao's small courtyard. This includes the engraving of the aura that can attract various attributes, the engraving that can help people hide the aura, and even the one-time consumption of the previous broken thunder. Zhu Yi had no way of understanding what those engraved as Gong would have these effects, so he could only memorize them in a gullible manner.

Anyway, in this part of the engraving, even if it is copied and copied, there is no problem. The most difficult part of refining is creating, and copying a work can be successful in most senses as long as it has a complete list of materials and engravings. For example, like Lang Evil Cave Heaven, as long as the original production process is reversed, and then after enough testing, unless there are some completely irreproducible situations, it is not too much of a problem to make such a spiritual weapon.

Therefore, Zhu Yi only needs to know what kind of effects these engravings have, and when the time comes, he needs to make his refining works have these effects, so he can depict these engravings. Of course, if you want to depict several engravings on a single refining work at the same time, it will be much more difficult. Because this is not only more difficult to portray, but the refiner must also consider whether the engravings will conflict with each other, or whether they need to be communicated and integrated to make the effect better.

Fortunately, Zhu Yi's memory is not bad, and it only took a few days to forcibly write down these engraved marks. However, forcibly writing down these engravings does not mean that Zhu Yi can start refining, he also has to have enough understanding of the materials, Feng Tianjiao put several thick books and notes in front of Zhu Yi after Zhu Yi wrote down those engravings, which recorded the characteristics of most of the known refining materials in the cultivation world.

Understanding marking is only the basics, and it is also necessary to have the right materials to match the engraving in order to produce the greatest effect. Otherwise, you carved an inscription that amplified the aura of the water line, and finally chose a material that increased the aura of the fire line, of course, the final effect is counterproductive.

After half a month, Zhu Yi felt that his brain capacity was a little insufficient. Although most of the cultivators' memories are good, it takes a lot of mental effort to sort out the relationship between these materials and the engraving.

"Alright, you can try to make some gadgets first. Don't think about ascending to the sky in one step, first choose to refine some spiritual treasures with a single function, such as the Sumeru ring, and wait until you are familiar with the steps of smelting materials and engraving and engraving, and then try something else. ”

After Zhu Yi finished reading the ancient books and notes describing the materials in his hand, Feng Tianjiao finally nodded with satisfaction and agreed with Zhu Yi to start the actual battle.

"Sumeru ring?" Zhu Yi also understood that it was impossible to swallow a big fat man in one bite to do anything, and his original plan was to try to take the first step out of his refining weapon from a small gadget, but when he heard Feng Tianjiao's suggestion, his eyes couldn't help but light up.

The function of the Sumeru ring is indeed very simple, and it can only be used for storage. For skilled refiners, as long as there are materials that can carry spatial attribute engravings, they can be quickly refined. Moreover, a Sumeru ring does not need many materials, materials that can carry spatial attribute engravings, such as star iron, Feng Tianjiao has a lot here, enough for Zhu Yi to try, even if he fails, he can come again.

"Okay! Let's make a Sumeru ring and give it a try!" Zhu Yi nodded at Feng Tianjiao, and then selected a piece of star iron the size of a human head from Feng Tianjiao's material library.

To make a Sumeru ring, you actually only need a thumb-sized piece of star iron, but the texture of star iron is very tough, even a superb spirit soldier like the Tiger Roar Knife is difficult to cut it, but Star Iron also has one of the biggest problems, that is, it is not resistant to high temperatures.

Of course, normal flames are useless, but some exotic flames with extremely high temperatures can easily be smelted and separated. It just so happened that Zhu Yi's extreme yang power could easily form the Xuanzhi True Flame, although it was not a very powerful alien fire, but it was enough to smelt it away.

The aura was running, and a flame appeared on Zhu Yi's fingertips, and then Zhu Yi swiped on the star iron with the size of a human head, and the extremely high temperature flame was like a sharp blade, and a piece the size of a thumb was easily cut off on it.

That small piece of star iron fell into Zhu Yi's palm, and Zhu Yi quickly used Xuanzhi True Flame to refine it, turning it into a piece of molten iron flowing in Zhu Yi's palm.

As soon as his mind moved, a trace of Zhu Yi's divine thought fell into the molten iron, commanding Xuanzhi Zhenyan to pull the molten iron, and then slowly lowered the temperature of the palm, and a rough ring appeared in Zhu Yi's palm.

"Whew!" Zhu Yi exhaled softly, sweat was already dripping down his forehead, he didn't expect that controlling Xuanzhi True Flame would consume so much soul power. In the past, all he had to do was to use the Xuanzhi True Flame to fight the enemy, that is to say, he simply released the flames out of the flames, but now he had to control the flames to carry out some extremely extreme actions, which was naturally very exhausting.

After forming the prototype of the ring, Zhu Yi lowered the temperature of the flame again, and at the same time, the fingers of his left hand slowly swiped over the palm of his right hand, raising the temperature of a wisp of flame, and quickly brushing over the surface of the ring like a tongue of fire. Zhu Yi didn't want to make a rough semi-finished product, now what he has to do is to polish the mold to perfection, and the more perfect the mold, the more conducive to the next step of engraving, so that the trajectory of the engraving will not be affected by the texture of the material itself.

"Ice!"

When the mold gradually perfected, Zhu Yi's left hand slapped suddenly, and a frost force directly hit the ring, quickly solidifying the ring model.

As Zhu Yi smashed the frost in his palm, a silver ring appeared in his palm, just casting such a ring consumed a lot of his mental energy, so that he had to stop and sit down to recover his soul power through meditation.

Because what Zhu Yi has to do next is to have a storage function under the internal engraving of this silver ring, which must be completed at one time when engraving the engraving, once there is a pause in the middle, there will be a break point in the engraving, which will affect the effect of the engraving at least and make the engraving completely invalid.

That means that Zhu Yi's refining is a complete failure, and he has to start all over again.

After resting for about a stick of incense, Zhu Yi's soul power had basically recovered, and he opened his eyes and began to look at the ring in his palm. There is no texture on the surface of this silver ring, unless it is some extremely special material, which needs to be engraved and carved with the help of the natural texture, generally speaking, the less the texture on the mold used for refining, the better, so as not to be disturbed when carving, and now Zhu Yi's ring is qualified from the mold.

"Then there's the engraving. ”

Zhu Yi reviewed in his mind the spatial seals he had seen before with storage functions, chose the simplest one, and then began to meditate in his mind.

Even if there is a ready-made engraving pattern, it is not simply engraved on the material, but also needs to be modified and improved to a certain extent according to the shape of the mold formed by the material itself. If you simply copy it, you may not be able to complete the engraving due to the mold.

Therefore, before the official start, the refiner will carry out the idea meditation in his mind, so that the final engraving plan conforms to the characteristics of the mold itself.

The ring is a relatively simple mold, so soon Zhu Yi thought about his final engraving plan, spit out the aura in his hand, and condensed it into an extremely fine spirit needle with the aura, and at the same time attached the Xuanzhi True Flame to it, and began to carve it on the ring, showing the pattern in his mind on the real material.

At this moment, Zhu Yi's entire mind was immersed in the ring in his hand. The first time he engraved and depicted, Zhu Yi was also quite nervous, for fear that there would be any problems, especially because he was afraid that his soul power would not be able to keep up. Because Zhu Yi had already discovered when he was refining the mold just now, the biggest consumption of refining was not the spiritual energy, but the amount of soul power, because these were all subtle controls, and they had to be fully focused on using the amount of soul power to control.

As the spirit needle crossed the ring, a pattern was quickly outlined on the ring, and this pattern continued to spread with the movement of the spirit needle, but Zhu Yi's face was beads of sweat the size of beans dripping down. Zhu Yi didn't expect that just directing the movement of the spirit needle would consume a lot of his soul power, not to mention that he still had to constantly refine the previous meditation plan in his mind, so that the entire engraving could be perfected.

When Zhu Yi commanded the spirit needle to cut through the last part of the blank space on the ring, connecting the end and beginning of the trajectory together, a faint light flashed from the ring, and at this time Zhu Yi finally let out a long breath, in the process of carving the mark just now, he actually held his breath the whole time, for fear that the action of breathing would affect the mark.
