A cluster of orange-red flames ignited, growing dozens of times stronger between breaths, forming a blazing fire.

With a sweep of his divine sense, he roughly estimated the upper limit of the excitation temperature of the Agni Array.

"Between four hundred and five hundred, the spiritual power urging formation method is introduced, and the power can be slightly raised."

After all, it's just a primary formation, and the power is really pulling the hips.

"But it doesn't matter, just change to a stronger fire-gathering formation."

As it turned out, her idea was still viable.

The formation is matched with the structure, and the spirit gathering array is used as the base, which can replace part of the work links.

What Xu Qiuyue didn't understand was that in the Great World of Cultivating Immortals, her idea had already been applied, and that was the famous Earth Fire Room.

The prototype design test passed, and Xu Qiuyue immediately stopped it for a major change.

"The formation burning medium is aura, as long as the aura is filled enough, the temperature can be piled up."

Thinking about her own experience, Xu Qiuyue also felt a little funny: "It's always weird to do this in the world of cultivating immortals. ”

"It stands to reason that the flame induced by the monk should be called a spiritual fire."

"And this spiritual fire should also have its exclusive nickname and nickname."

The special spiritual fire that Xu Qiuyue said, of course, exists in the Great World of Cultivating Immortals, and it is difficult to obtain high-level spiritual fire, but low-level spiritual fire is very common.

Generally speaking, alchemists and refiners will master one or two special spiritual fire techniques.

Not only is the Spiritual Fire hot, but it also has some special effects attached to it.

Someone like her, who uses the Agni Array as the core of the fire source, can only be said to be an anomaly.

Half an hour later, the new version of the formation combination was fiddled out by her.

The Spirit Gathering Array is matched with the most explosive Sun Array in the primary formation.

Xu Qiuyue tried to throw in a small piece of dark iron ore.

Due to the design being too leaky, the ore had to be held by Xu Qiuyue herself.

Time is spent testing and revising over and over again.

After the first few days of unrest, the people of Xuangui Island also returned to their previous rhythm of life.

The sun rises in the east and sets in the west, and it is three months in a blink of an eye.

Xu Qiuyue tinkered with the design during the day, meditated and practiced at night to refine the spiritual power in the body, and lived a leisurely and comfortable life.

"Wow, it's really done."

On this day, Xu Qiuyue let out an exclamation.

In front of me was a large furnace six or seven meters high.

A sense of pride arose, and from now on she was also a big touch of DIY.

The results of the three-month design, Xu Qiuyue gathered it all in a furnace.

With the blast furnace as the carrier, the four main formations of carving, gathering spirit, scorching sun, hanging and hurricane are the core drives.

In addition, the interior of the refining furnace is also designed with a multi-layer inner wall, which is also engraved with a formation inscription of the refractory series.

The first two Spirit Gathering Arrays and the Burning Sun Array remained unchanged from the previous assumptions, and the last two formations were used to lift the materials in the furnace and separate impurities.

The whole design adopts the formation to link each other as the axis, and the formation effect is strictly controlled within a specific range.

For example, the Burning Sun Array is confined to the heart of the furnace, and the walls of the furnace are blessed with fire-resistant inscriptions to avoid the risk of being scorched and melted by the flames.

"The ore is purified and melted, and it can be handed over to the refining furnace, and then the plasticity is very simple, and it can be kneaded into a specific shape with the technique of controlling things."

"The most troublesome step is to carve the formation and inscriptions."

"I really can't figure out how to automate this step."

Xu Qiuyue had a little distress on her face, it stands to reason that this step, with the printing mode, can be formed in one piece.

But the problem was that she couldn't think of any knife head materials that could rub formations and inscriptions.

Since ancient times, formations have either formed naturally or artificially arranged in the Great World of Cultivating Immortals, and there has never been a precedent for using other media to rub formations.

Of course, it is also possible that she is lonely and unheard.

"Let's refine the flying sword and test the water first."

Too lazy to think about the things that can't be done at the moment, Xu Qiuyue made a move and threw dozens of kilograms of dark iron ore into the blast furnace.

The Divine Consciousness is always aware of the changes in the furnace.

The baiterite was incinerated in the blazing fire, in which the impurities quickly softened, the inferior centrifuge formed by the hurricane gust buzzed, and the ore impurities were thrown out by centrifugal force.

Three hours passed quietly.

"There are still some impurities, but it's almost the same, it's just that the final product is just a little bit worse, anyway, it's not for my own use, it doesn't matter."

With this in mind, Xu Qiuyue was not ambiguous, and began the final step of refining the vessel, plasticity and writing inscriptions.

The so-called inscription, in the background of the game that Xu Qiuyue understands, is a natural language of heaven and earth, and has the effect of connecting the mysterious power.

There are thousands of ways to write a single font, such as Chinese Xingshu, Cursive, Kaishu, Subordination, and Seal Script.

For each way of writing, the final font molding is different, and the power released is also different.

Xu Qiuyue's expression was focused, and the slightest spiritual power was attached to the formed sword embryo, and she first chose to arrange a spirit gathering array for the sword embryo, and then outlined the inscription in the eye of the spirit gathering array node.

Strong, sharp is the primary inscription.

This is followed by inscriptions that allow the artifact to grow and size as it pleases.

"Add an inscription that can be made heavier."

As soon as the thought moved, he wrote the inscription of the mountain character to the embryo.

There are already five inscriptions on the front and back embryos, but Xu Qiuyue is not over, and there are still empty spaces on the sword body to operate.

Anyway, the materials are just some dark iron ore, even if you play with it, it's a big deal to return to the furnace and recast.

With such an idea, Xu Qiuyue tossed vigorously.

As she wrote the eighth sturdy inscription, the embryo cracked with a click.

"Well, what's wrong?"

Xu Qiuyue was a little confused, and she didn't know why the sword embryo collapsed.

If you don't understand, you can only keep trying.

Return to the furnace and quench at high temperature, so that the dark iron condensed into the sword embryo will be melted into a ball of molten iron again, and then taken out and re-condensed into the sword embryo.

This time, Xu Qiuyue slightly changed the layout of the Spirit Gathering Array at the base of the sword embryo, reducing its nodules from ten to nine.

When the eighth inscription was written, the blade cracked again.

"Tsk, either there is a problem with the layout of my formation, which leads to a conflict in the utility of the inscriptions, or the material can't afford to stack more inscriptions."

Two possibilities crossed my mind.

Quenched and reforged again, this time she wrote only seven inscriptions.

"It worked."

"But for Mao to be so dish, I'm dizzy."

Holding the newly baked Xuantie Sword Weapon, Xu Qiuyue was speechless.

"The increase in the power of the sword duel is better than nothing, but the sword attack is okay."

"It's obviously a magic weapon with seven inscriptions written on the handle, so it's a good grade, and that's it, that's it?"

This Xuantie Sword has almost no amplification effect on her, and it is not at all comparable to the Flying Snow Sword given to her by the patriarch.

You must know that the Flying Snow Sword is just a high-grade magic weapon.

After pondering for a moment, Xu Qiuyue thought of the crux of the problem: "The dark iron material is hard, but it has a very poor effect on increasing spiritual power. ”

"I should probably add some other materials and see if I can denature them."
