Huang Chiyan didn't say a word, he turned on the stove, and the phantom of the fire dragon appeared behind Huang Chiyan, and a judgment holy fire turned into a fire dragon and hovered under the refining furnace. After the flames were preheated, Huang Chiyan hurriedly took out his refining materials and the Burning Sky Sword, this time he was not going to refine a new magic weapon, but to improve his companion magic weapon.

The accompanying magic weapon, as the name suggests, is a magic weapon that accompanies a person throughout his life, and a martial artist can only have one accompanying magic weapon. There is a soul connection between this companion artifact and its owner, and no one but its owner can use it. This magic weapon is different from other magic weapons in that it can only follow one master, and it cannot change hands, nor will it be destroyed by the sword of the robber. Another important point is that he can be upgraded in different ways, these companion magic weapons can be used by the master at the beginning, z as the master becomes stronger step by step, its level also needs to evolve, and ordinary magic weapons have no way to evolve.

There are four ways to obtain this associated magic weapon, the first and most direct one is also the method obtained by Huang Chiyan's Burning Sky Sword, which is refined by the user himself and communicates with the magic weapon through blood sacrifices. The second is the one that relies more on fate, that is, when you encounter a certain magic weapon halfway through, it is very consistent with your own cultivation attributes, which naturally makes people one. The third is more common, that is, the ancestral inheritance, after the death of the previous generation, his magic weapon can be passed on to future generations through the bloodline, so that the magic weapon will not be destroyed. The fourth is the rarest one, and it is also a true companion spirit weapon, that is, a sword or knife that is born or found out of the body when it grows up.

This companion artifact will also evolve in various ways, and Huang Chiyan's one is the simplest one, upgrading the artifact by adding materials and a large array. Before the Burning Sky Sword was upgraded, it was equivalent to a magic weapon in the lower part of the Yuan Force level, but there was no clear information, after all, when refining the Burning Sky Sword at that time, it was completely made by blind confusion, and all kinds of attributes were not stable.

Huang Chiyan casually threw the Burning Sky Sword into the refining furnace, and the Flame Divine Dragon instantly surrounded the Burning Sky Sword and burned it. When the Burning Sky Sword softened, Huang Chiyan began to fuse materials, integrating the new refining materials he had prepared into the Burning Sky Sword.

After all, when Huang Chiyan was refining the Burning Sky Sword before, he used basic-level refining materials, and he felt that the grade was high enough at that time, but it was not enough to support a Yuanli-level magic weapon at all.

Huang Chiyan casually took out a piece of black metal one foot long, three inches wide and one inch thick, and there were a few less obvious patterns on this metal. This metal is called "Black Gold Dark Iron", which is ten times harder than ordinary refined copper, but it is also twice as heavy as refined copper, which is a necessary material for many heavy Yuanli-level magic weapons. Although his Burning Sky Sword was not a heavy weapon, Huang Chiyan needed this hard and heavy metal as the main body. This black gold black iron is not cheap, after all, there are many magic weapons in the upper section of the Yuan Force level will also use this material as the backbone, just this piece of metal that Huang Chiyan bought cost Huang Chiyan five pieces of great martial stone, this thing is definitely the most luxurious metal that Huang Chiyan has ever bought, and it is about to catch up with half the price of the finished product.

Huang Chiyan threw the black gold dark iron into the furnace in an instant, and the flame quickly surrounded it and began to refine it with the original Burning Sky Sword. This black gold black iron is very hard, and it takes four or five hours for ordinary refiners to refine it successfully, although Huang Chiyan didn't take that long, but he also used his Flame Divine Dragon to scorch for an hour in a row.

After the metal melted, Huang Chiyan waved his hands, and the Burning Sky Sword and the Black Gold Dark Iron began to approach each other under the traction of the Flame Divine Dragon, ready to merge. As Huang Chiyan struck with a shaping hammer, the black gold black iron began to slowly devour and replace the refined copper on the Burning Sky Sword, and the sword body also turned dark purple.

At this time, Huang Chiyan took out another piece of red metal, which looked much less than the black gold black iron, but it had a scorching aura that the black gold black iron did not have. This metal is the "Flame Red Gold" that Huang Chiyan bought with two large martial stones, which is also a rare metal used to refine the weapons of the upper stage of the Yuan Force level, and it has a sharp aura and the coercion of flames.

Huang Chiyan threw the flame red gold into the furnace and began to scorch it with the Flame Divine Dragon, scorching it with a shaping hammer as he could, and gradually hammered it into a long thin edge.

Huang Chiyan began to fuse this thin edge with the Burning Sky Sword, and soon after, this flame red gold was inlaid into the Burning Sky Sword, turning into flame patterns, forming a sword blade in the outermost layer.

Most of the formations on this Burning Sky Sword are the basic-level formations engraved by Huang Chiyan, and there are quite a few of them, Huang Chiyan only needs to upgrade these formations to Yuanli-level formations, and then sort out the position and function of each formation.

Although it is simple to say, Huang Chiyan is really very troublesome to do, he needs to expand and upgrade the lines of each large array, and he has to sort out these formations. These formations are very troublesome to sort out, each formation is independent, and it is not an easy task to form them into a unity. What's more, what makes people even more troublesome is that Huang Chiyan didn't understand these things before, he just superimposed all kinds of formations in one go, and didn't consider the question of whether one plus one can equal two.

I'm so troubled now, it's just that I didn't read much back then. Huang Chiyan guarded these large arrays as if he was looking at a mess, and he couldn't find a clue at all. He could only scratch his head helplessly, guiding the big array little by little.

"Young man, there are no tricks, right? In the future, you will decorate less outside and learn more, and when the book is used, you will hate to understand less?" At this time, Jin Sheng, who was awake in the sea of Huang Chiyan's consciousness, began to teach Huang Chiyan a lesson.

"Jin Lao, I know that I am wrong, I will definitely read more books and newspapers in the future, and study hard every day. The main thing is that there is no way to do it now, so I can only hold on to it temporarily, Jin Lao, please give me some pointers. Huang Chiyan heard Jin Lao's voice as if he saw a life-saving straw, and hurriedly asked for a solution.

"If you want so many formations to be unified together, you can't do it unless you do a multi-chain arrangement, or use the method I created, "Nested Chains". ”

"What is a nested chain, and how should I get a nested chain?"

"Nested chains are something I've created, but they've been around the world. However, there are not many people who really master this method, and they think that a main formation with a few small formations will be over, but this is not the case. ”

"Jin Lao, don't talk about your glorious history, this is at a critical juncture, please teach me what kind of nested chain is this. ”

"What's in a hurry, I can't eat the hot magic device in a hurry. "Jin Lao is not in a hurry at all, if he is really in a hurry, he is not in a hurry.

Huang Chiyan was in a hurry there, scolding this golden saint secretly, "You're not in a hurry, but my Burning Sky Sword is about to be scrapped." I'm still anxious to eat the hot magic device, what the hell are you meowing eater?" But of course he wouldn't show it on the surface, and he still said with a smile on his face: "Don't you think your Buddha's foot is reliable?"

The Jin Sheng also laughed and said: "You really hugged the Buddha's feet right, and I will teach you this mosaic chain method." ”

"The mosaic chain method is not just a way to stuff the formation into the big formation, but to use the entire magic weapon as the medium, the whole magic weapon as the array, and all the small formations as the formation eyes, converging into a powerful super formation, which is a combination of multiple formations. ”

Hearing this, Huang Chiyan hurriedly began to arrange the general formation outside the Burning Sky Sword, and he wanted to use all the formations as the eyes, which was very difficult, and if he didn't get it right, it would lead to disordered formations.

Huang Chiyan was wholeheartedly arranging the formation, there were small formations in the big array, and the small arrays were all the eyes of the big array, and all the arrays were turned into part of the magic weapon Burning Sky Sword.

When Huang Chiyan integrated all the formations, he felt that all the formations were integrated, and this kind of operation required extremely powerful mental control and very profound formation comprehension.

After about half an hour, Huang Chiyan finally finished sorting out the big array, and all the formations were also proceeding in an orderly manner. Huang Chiyan took out a piece of Flame Dragon's Blood Stone from his arms and inlaid it on the Burning Sky Sword, as the eye of the entire large array of the Burning Sky Sword. We have also introduced this flame dragon's blood stone before, so I won't go into too much detail here. The function of this flame dragon blood stone is not only to enhance the flame cultivation and cultivation of flame cultivators, but the most important function is to serve as the array eye of magic weapons and the treasure of suppressive weapons. The Flame Dragon's Blood Stone can be used as a center for energy absorption, storage, and provision in a formation, among which the Flame Dragon's Blood Stone can give the Burning Sky Sword a monstrous flame aura.

As the Flame Dragon's Blood Stone was placed on the Eye of the Array, there was a Flame Divine Dragon hovering above the Burning Sky Sword, and a moment later, the Flame Divine Dragon was engraved on the Burning Sky Sword, becoming a pattern of the Flame Divine Dragon engraved on the sword body of the Burning Sky Sword.

Huang Chiyan held the Burning Sky Sword in his hand, and the Burning Sky Sword shook in Huang Chiyan's hand, and a dragon roar came from the sword, and then it gradually quieted down.

Huang Chiyan felt that the Burning Sky Sword in his hand had transformed, and Huang Chiyan felt the heat and resonance in the Burning Sky Sword. At this time, the Burning Sky Sword still looks like a magic weapon in the lower part of the Yuan Force level, but its power may not be able to compete even if it is a top-level magic weapon in the upper Yuan Force level. Huang Chiyan felt that with this Burning Sky Sword, he could already compete with the masters of the Ning Yuan Realm, and could even defeat the masters of the Ning Yuan Realm when the bloodline was completely exploding, which was equivalent to Huang Chiyan making a defense for the potential Dabido.
