Spiritual materials are the unique classification of heavenly materials and earth treasures in the cultivation world, which are divided into nine grades, one of which is the best and the last of the nine grades.

The biggest difference between spiritual materials and mortal things is that spirituality and natural prohibitions, without spiritual and natural forbidden materials, no matter how excellent their essential attributes are, they all belong to the scope of mortal things.

Sometimes the value of the Nine Rank Spiritual Materials is not as good as some precious mortal things, probably because the Nine Grades Spiritual Materials have no natural prohibition, as long as they are spiritually abundant, some materials with missing rune seeds can be classified as Nine Grade Spiritual Materials.

Therefore, the nine-grade spiritual material can be made in large quantities from ordinary things, and some precious metal alloys, such as bronze, purple gold, platinum and other materials, can be moistened with mana when making them, and most of them can get the nine-grade spiritual material.

The condensation of some heaven and earth essences, extracting spirituality with mana, can also obtain nine-grade spiritual materials.

Therefore, the nine-grade spiritual material is the most changing in the grade of the spiritual material, and the precious one can be exchanged for the material that is three or four grades higher than it, and the rough and easy to obtain can be bought in three or four taels of gold.

The life and death wheel banner that Du Xu wants to refine, the main materials are black silk and evil bones, which are all artificially refined materials, and the grade is determined by the degree of refinement of the materials.

A material like the black silk that is refined by the yin soul, yin qi, and evil qi, the yin soul of ten people can only be refined, and even the black silk of the nine grades of spiritual materials is barely refined, and the yin souls of a hundred people can refine ordinary nine grade spiritual materials, and the yin souls of a thousand people can refine the best nine grade spiritual materials.

If it reaches 10,000 Yin Souls, it can refine eight-grade spiritual materials, 100,000 Yin Souls can refine seven-grade spiritual materials, and Black Silk can reach the level of sixth-grade spiritual materials at most, then at least 100 million Yin Souls are needed.

The black silk refined by Du Xu devoured many old ghosts, and the quality was also a top-grade spiritual material among the eight grades, and the evil bones could only barely enter the eighth grade.

But even if this is the case, the Wheel of Life and Death Banner that Du Xu is preparing to refine is also a first-class good embryo. In the future, devour more ghosts and zombie bones, and the quality can be improved to another level.

The Wheel of Life and Death Banner is a magic weapon of the Yin attribute, and the forbidden rune seeds are also all runes, and the runes of Yin, death, Mi, life, and soul are consistent with the natural prohibition of materials such as black silk and evil bones, so Du Xu was able to refine to the level of the fivefold prohibition so quickly.

The prohibition of the Wheel of Life and Death - The Wheel of Life and Death eliminates the prohibition of karma, there are many rune seeds and materials that are compatible, and there is no need to work hard to collect the spiritual visualization of heaven and earth, and it can be formed with a little mana sacrifice, but now Du Xu wants to refine the evil bones into a banner and completely practice the Wheel of Life and Death Banner.

This requires the qualitative nature of true fire, and the use of a firepower bred by true qi to quench the magic weapon tire. In this way, the two materials can be mixed into one, perfectly integrated and functional.

Du Xu took out hundreds of evil bones, shot them in front of him with true qi, and carefully spewed out a stream of true fire.

True fire is not a flame, it is more like a high-frequency vibration movement of true qi, the true air flow molecules oscillate at high frequency, decomposing the composition of materials, even ice, water, snow and other materials that can melt can be refined.

In fact, most of the "fire" that practitioners talk about is something of this nature, thunder fire is thunder and lightning that moves at high speed, and yin fire is yin energy that moves at high speed, and the so-called "fire" is probably high-frequency vitality. Because it expresses the form of fire, it is called "fire".

In front of Du Xu, a wisp of true fire wrapped hundreds of evil bones.

The evil bones like beautiful jade, slowly decomposed into jade-colored mist in the real fire, one wisp, two wisps, gradually the evil bones in the real fire became fewer and fewer, and the floating jade-colored mist became thicker and thicker, after half an hour, all the evil bones were decomposed into mist, and the rich white jade-colored mist gathered into a ball, as if there was a cloud of jade water floating in the air, and the jade water on the surface followed a mysterious trajectory, slowly flowing.

The surging yin qi contained in this made Du Xu a little frightened, like walking on thin ice.

The True Fire Refiner is really extraordinary!

Du Xu's soul was immersed in it, and unconsciously, his pupils turned into clear silver, which was a sign of a large use of soul power, and Du Xu usually did not dare to use his powerful innate soul power at will.

The trance-like state is turned on, and the power is one hundredth.

Du Xu didn't pay attention to his instinctive reaction at this time, his mind was immersed in the refining weapon, this refining process was not easy, but for him, it was also a rare realization. Whether it was a true fire refining weapon or refining evil bones, it was the first time he had tried.

The fusion of true fire and evil bones gave birth to countless changes, many changes that he had never seen before.

The natural prohibition on the evil bones, in the process of refining, the rune seeds are constantly broken and reorganized, like pieces of fine building blocks, forming new rune combinations. Some of them are prohibitions, while others are just disorderly piles up that require the practitioner to sift through them and experience the changes in these prohibitions.

Different cultivators, through different ways to comprehend, to screen, according to the composition of the prohibition of the magic weapon, to influence the composition of the prohibition with divine thoughts, to combine the matching runes into the prohibition, the whole process of different practitioners have different methods, but the essence is the same.

Without such refining, no matter how perfect the material is, no matter how perfect the natural prohibition of spiritual materials is, it cannot be correctly affected during tempering, and it fails to form a talisman prohibition that is consistent with the prohibition of magic weapons, then ten points of materials can only play a role of one or two points.

Du Xu was immersed in this magical world, and the thin ice in his heart gradually disappeared, and he was so focused on forgetting himself that he didn't notice the continuous exertion of his divine soul's power.

In a trance-like state, the power is 6 percent ~~~ 10 percent ~~~ 50 percent~

I saw that the real fire in front of him suddenly fluctuated and slowed down, like a wild horse being tamed.

The jade-colored mist of evil bones also changed rapidly, and the original wisps of mist gradually condensed, and a short jade pillar condensed, and the mist extended upwards along that jade pillar, and soon formed a jade rod. A trace of true fire seeped into the jade rush, and beautiful silver fine lines began to appear on the surface of the jade rod.

If you look closely, this silver pattern is composed of countless silver runes, which are linked to each other and form a mysterious pattern prohibition according to the "Wheel of Life and Death Elimination Karma Prohibition".

Du Xu continued to visualize the rune prohibition, colluding with the spirituality of heaven and earth, and punched out silver runes one after another, with more and more silver patterns, as if silver vines were spreading and growing wildly along the jade pole.

Du Xu opened his eyes suddenly, and with a casual move, the jade rod fell into his palm.

I saw that the jade rod jade color is warm, long and long, and the silver lines on the rod are complex like flowers, covering the surface of the jade rod, but it is like an ordinary pole, and there is no trace of breath exposed.

This is not over, Du Xu summoned the black cloth behind him, and the real fire skyrocketed here, wrapping the jade rod and black cloth in it.

The black cloth is glorious and generous in the real fire, and the black cloth that was originally black and inconspicuous is under the calcination of the real fire, the faint light flows, and the texture of the cloth on the surface gradually disappears, as if the black cloth has changed from a black reflective plastic cloth.

With the light circulating on the banner surface, it is the forbidden pattern of the cycle of life and death to eliminate the prohibition of karma, and the complex silver pattern forms the shape of a compass on the banner surface.

The compass-like pattern slowly rotates with the fluctuation of light, and the endless silver runes form a rune array, constituting a semi-substantial entity of the compass, and if you look closely, you can also see that the rune array is divided into five layers, and the compass is from the center to the outside, the more complex and cumbersome the runes are composed.

This is the form of the innate spirit treasure life and death reincarnation heavenly disk, representing part of its power essence, life and death reincarnation elimination of karma prohibition, is to imitate the innate prohibition of this innate spirit treasure.

As soon as the five-layer rune array that constitutes the compass appears, the natural prohibition of black silk will be raised, and these scattered prohibitions will fall into the compass, and in the rotation of the compass composed of the five-layer prohibition, they will be broken up into runes and absorbed.

These scattered runes are outside the compass prohibition, faintly forming a phantom of the rune array, vaguely as if it is another layer of compass.

Du Xu didn't expect that the prohibition of the Wheel of Life and Death Banner would reach the sixth level so soon, and he connected the black banner with the jade rod with real fire.

The fusion of two different materials together constitutes a magic weapon, which is quite a test of Du Xu's ability.

Du Xu's eyes were silver, and his soul was in a trance state of 200 percent, and he was overclocking to use the power of his soul.

At this time, in Du Xu's eyes, everything turned into a silver rune combination, and the banner and pole in front of him were two complex forbidden patterns, some of which were incongruous.

Under the observation of Du Xu's divine soul power, the uncoordinated runes were very prominent, and in the blink of an eye, they were refined into the prohibition by the True Qi Sacrifice, the prohibition shook slightly, and the flow of power became smoother.

Next is the critical moment, Du Xu wants to integrate the prohibition of the banner pole with the prohibition of the banner.

Under Du Xu's divine sense, the jade-colored banner decomposed into silver forbidden patterns, and under Du Xu's control, it flowed into the five-layer compass prohibition, and was broken up by the compass into silver light dots.

The dots of silver light were all rune seeds, they were scattered in shape, but they were more closely connected, and the dots of silver light merged around the vague outline of the compass's periphery.

The fuzzy talisman array on the outermost part of the forbidden compass was magnificent, and gradually became clear, colluding with the laws of heaven and earth, turning into a complete prohibition.

The fivefold rune prohibition of the forbidden compass was added in the blink of an eye, and the patterns that made up the compass suddenly became dozens of times more complicated.

Du Xu didn't expect that the prohibition of the Wheel of Life and Death would actually go one step further, and the sixth prohibition would be refined, and the fluctuations when the magic artifact embryo was consummated consolidated the prohibition again.
