Spiritual materials are the unique classification method of heaven, earth treasures in the world. They are divided into nine grades, the first grade is the best, and the ninth grade is the last.

The biggest difference between spiritual materials and ordinary objects is spirituality and natural prohibitions. Materials without spirituality and natural prohibitions, no matter how excellent their essential attributes are, they all fall within the scope of ordinary objects.

Sometimes the value of ninth-grade spiritual materials is not as valuable as some precious ordinary things. It is probably because the ninth-grade spiritual materials do not have natural restrictions. As long as the materials with abundant spirituality and some defective rune seeds can be classified as ninth-grade spiritual materials.

Therefore, nine-grade spiritual materials can be made in large quantities from ordinary objects. Some precious metal alloys, such as bronze, purple gold, platinum and other materials, can be moistened with magic power when making them, and most of them can get nine-grade spiritual materials.

The condensation of some essences of heaven and earth can also extract spirituality with magic power, and you can also obtain ninth-grade spiritual materials.

Therefore, the ninth-grade spiritual materials are the most varied among the spiritual materials. The precious ones can be exchanged for materials that are higher than the third and fourth grades. The rough and easy-to-get them can be bought in three or four taels of gold.

The main materials of the life and death wheel flag that Du Xu wanted to refine, the black silk and evil bones, are all manually refined materials, and the grade is determined by the degree of refining the material.

For materials like Hei Qiansi, which are refined from Yinhun, Yinqi, and evil energy, ten people's ghosts can only be refined. Even the ninth-grade spiritual materials are barely blackhun, hundreds of people's ghosts can refine ordinary Ninth-grade spiritual materials, and thousands of people's ghosts can refine the best Ninth-grade spiritual materials.

If you reach the level of the ghost of ten thousand people, you can refine the eighth-grade spiritual material. If you reach the level of the ghost of ten thousand people, you can refine the seventh-grade spiritual material. Black silk can reach the level of the sixth-grade spiritual material. That will require at least 100 million people.

The black silk refined by Du Xu swallowed many old ghosts. The quality of the eighth grade is also of the best spiritual material, so evil bones can only barely enter the eighth grade.

But even so, the life and death wheel flag that Du Xu prepared to refine is a first-class and good embryo. In the future, he will devour some ghosts and zombies and bones, and the quality can be added to another level.

The Life and Death Rotation Banner is a magic weapon with Yin attributes, and the ban rune seeds are also all, such as Yin, Death, Mi, Life, Soul, etc., which are consistent with the natural bans of materials such as Black Slide and Evil Bone, so Du Xu sacrificed and refined to the level of the fifth level of ban so quickly.

The prohibition of the Life and Death Rotation Banner - the Life and Death Rotation Banner eliminates karma. There are many rune seeds and materials that match the spiritual visualization of heaven and earth without having to work hard to collect spiritual imagination of heaven and earth. You can be formed with a little magic power. But now Du Xu wants to refine the evil bones into a flagpole and completely practice the Life and Death Rotation Banner.

This requires the true fire to be determined, and a firepower nurtured by the true qi is used to temper the magical instrument and body. Only in this way can the two materials be mixed together, perfectly integrated and function.

Du Xu took out hundreds of evil bones, used his true energy to capture it in front of him, and carefully sprayed out a stream of true fire.

True fire is not a flame. It is more like a stream of true qi that vibrates and moves at high frequency. The molecules of true qi oscillate at high frequency, decomposing the composition of the material. Even ice, water, and snow, which melt, can be refined.

In fact, most of the "fire" mentioned by practitioners are of this nature. Thunder and fire are thunder and lightning that moves at high speed, and Yin fire is yin energy that moves at high speed. The so-called "fire" is probably high-frequency vital energy. Because it shows the appearance of fire, it is called "fire".

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

The evil bones, like beautiful jade, slowly decomposed into jade-colored mist in the true fire. One wisp or two wisps, gradually, the evil bones in the true fire became less and less, 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, just like a ball of jade water floating in the air, and the jade water on the surface slowly flowed along a mysterious trajectory.

The surging yin energy contained in this made Du Xu feel a little frightened and walking on thin ice.

True fire refining weapon is indeed extraordinary!

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

The soul trance state is turned on, with one percent power.

Du Xu did not pay attention to his instinctive reaction at this time. His mind was immersed in the refining of the weapon. The refining process was not easy, but it was also a rare experience for him. Whether it was the real fire refining of the weapon or the tempering of the evil bones, it was his first attempt.

The true fire and evil bones blended together, and countless changes were produced, many changes he had never seen before.

The natural ban on evil bones, during the refining process, the rune seeds are constantly broken and reorganized, like pieces of tiny building blocks, forming a new rune combination. Some are bans, while others are just disorderly piled up, which requires practitioners to screen and experience the changes in these bans themselves.

Different practitioners experience and screen through different ways, use divine thoughts to influence the composition of the prohibition based on the composition of the Dharma instruments and use divine thoughts to combine the corresponding runes into the prohibition. Different practitioners have different methods throughout the process, but their essence is exactly the same.

Without such tempering, even if the materials are perfect and the natural ban of spiritual materials are perfect, the correct effect cannot be formed during tempering, and the talisman array ban that is consistent with the ban on magic instruments is not possible, then a 10-point material can only play a role of one or two.

Du Xu was immersed in this magical world, and the thin ice in his heart gradually disappeared. He focused on forgetting himself and did not notice the continuous use of the power of his soul.

The soul is in a trance state, with six percent power~~10 percent~~50 percent~

The true fire in front of him suddenly fluctuated and slowed down, just like a wild horse being tamed.

The jade-colored evil bone mist also changed rapidly. The original fog gradually condensed, and a short piece of jade pillar condensed. The mist extended upward along the jade pillar, and soon formed a jade pole. A trace of true fire penetrated into the jade pole, and beautiful silver fine lines began to appear on the surface of the jade pole.

If you look closely, these silver patterns are composed of countless silver runes, which are connected to each other and form a mysterious pattern ban according to the "Prevention of Life and Death Rotation and Elimination of Karma".

Du Xu kept visualizing rune bans, colluding with the spirituality of heaven and earth, and casting silver runes one after another. There were more and more silver patterns, just like silver vines spreading and growing wildly along the jade pole.

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

I saw that the jade pole was warm and about a meter long, and the silver patterns on the pole were complex like flowers, covering the surface of the jade pole, but it was like an ordinary pole, without a trace of exposure.

It was not over yet. Du Xu attracted the black cloth behind him, and the true fire soared here, wrapping the jade pole and black cloth.

The black cloth is radiant in the true fire. The originally black and inconspicuous black cloth flows lightly under the calcination of the true fire, and the texture of the cloth on the surface gradually disappears, just like a black cloth turning into a black reflective plastic cloth.

The banner surface made of black silk, silver patterns floated on the banner surface, and as the light flowed on the banner surface, it was the prohibition pattern of the cycle of life and death and the complex silver patterns formed the shape of a compass on the banner surface.

The compass-shaped pattern slowly rotates with the fluctuations of light. Endless silver runes form a talisman array, forming a semi-substantial entity of the compass. If you look closely, you can also see that the talisman array is divided into five layers. The more the compass goes from the center, the more complex and complicated the runes formed.

This is the form of the innate spiritual treasure, the cycle of life and death, and represents part of its power essence. The cycle of life and death is the innate prohibition of eliminating karma, which is to imitate the innate prohibition of this innate spiritual treasure.

As soon as the five-layer talisman array forming the compass appears, a natural restriction of black and silk is formed. These scattered restriction fall into the compass, and during the rotation of the compass formed by the five-layer ban, it is broken into runes and absorbed.

These scattered runes formed a phantom of a talisman array outside the compass ban, and seemed to be another layer of compass.

Du Xu did not expect that the ban on the Life and Death Rotation Banner would reach the sixth level so soon. He connected the black banner with the jade pole with true fire.

The two different materials are combined to form a magic weapon, which is quite a test of Du Xu's ability.

Du Xu's eyes were full of silver light, his soul was in a trance state of 200%, and he overclocked the power of his soul.

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

Under Du Xu's soul power, the inconsistent runes were very prominent and obvious. In a blink of an eye, they were refined into the ban by the true qi. The ban shook slightly, and the flow of power became smoother.

The next moment is the critical moment, Du Xu wants to merge the ban on the flag pole with the ban on the flag surface.

Under Du Xu's spiritual consciousness, the jade-colored banner poles were broken into silver prohibition patterns. Under Du Xu's control, it flowed into the five-layer compass ban, and was dispersed into silver dots by the compass.

The silver lights are rune seeds. They are broken up into shapes, but the connection is closer. The silver lights merge into the blurry outline of the compass.

The fuzzy talisman array on the outermost periphery of the ban compass is brilliant and gradually becomes clearer, connecting with the laws of heaven and earth, turning into a complete ban.

The fifth rune ban on the ban compass was added in a blink of an eye, and the patterns that formed the compass suddenly became dozens of times more complicated.

Du Xu did not expect that the ban on the Life and Death Rotation Banner would be further improved, and the sixth level of ban was refined. The fluctuations when the magic weapon embryo were perfected consolidated the ban again.
