After meditating for a few days and recovering his magic power to its best state, Old Demon Pang walked under the silver skeleton and began to adjust the formation, transforming the square circle into a huge circular circle.

At the same time, he took out five high-grade spirit stones of gold, wood, water, fire, and earth, as well as a small bottle of pure true demon water, and placed them in all corners of the circle.

The cave where Old Demon Pang is located is full of demonic energy, and only by using high-grade spirit stones can it provide the essence aura needed by the second stage of the Jade Bone Human Demon.

High-grade spirit stones are very rare in the world of cultivating immortals, and often one or two pieces may appear in a large spiritual vein, which is something that can not be found, even if it is an ordinary Yuan Infant Stage cultivator, there may not be one on his body.

This time to refine the jade bone human demon, just the high-grade spirit stones, Pang Lao Mo prepared more than twenty pieces.

The scarce xenomorph spirit root demon cultivator, the bones comparable to the magic weapons of the maturity stage, a large number of silver dragon meteoric iron, the bones of the demon generals, and all kinds of auxiliary materials are extremely precious.

As a great cultivator, Pang Lao Mo relied on the resources of the Blood Refining Sect to barely collect them all, and there was only one chance to refine them.

After arranging the magic circle, the magic light of Pang Lao Mo's hands flashed, and the xenomorph bones and Nie Wufeng shrouded in the magic net not far away slowly floated over.

Wind, thunder, ice, and darkness faced each other, suspended above the new circular circle, surrounding the silver bone cornerstone in the middle.

The old devil's hand was pinched, and an inexplicable fluctuation of soul power emerged, turning into black spiritual light, and submerged into Nie Wufeng's eyebrows.

"Nie Wufeng, the combination of the old man's soul condensation technique and the Blood Demon Network can ensure that in the case of your physical death, your soul will survive for half a day, and you can still control your wind spirit root in this half a day. ”

Old Demon Pang hesitated slightly, and then said: "Not long ago, the old man arranged for someone to investigate, and the remaining disciples of the Yueyang Sect in the foundation building period have already settled down in the Chu State and set up a small sect called the Treasure Pavilion, and in cooperation with the Transformation Spirit Sect, your Yueyang Sect can be regarded as a successor." ”

"Zhu Siming also went to the Chu State, so he must be able to find them. ”

A look of surprise flashed in Nie Wufeng's eyes, and then he said seriously: "Thank you seniors for informing me, Nie Wufeng promised seniors that he would definitely go all out." ”

Old Demon Pang said with satisfaction: "Very good, the wind attribute is the last one, pay attention to the fusion technique of other attributes." ”

"Yes, Senpai. ”

With a move from Old Demon Pang's hand, the thunder spirit root bone wrapped in the blood-purple magic net rose into the air, and then several materials full of thunder attributes appeared in the air, and a handful of blood-red flames enveloped them all.

Although these materials are precious, they are not the same grade as the Silver Dragon Meteorite in terms of materials, and under the true fire of Pang Lao Mo's Yuanying Immortal, they quickly turned into liquid and fused with the Thunder Spirit Root Bone.

After more than an hour, the flames dissipated, and this thunder bone was wrapped in a blood-purple magic net, barely worthy of the appearance of a human bone, and if there was no magic net, I am afraid that it would directly turn into a pile of liquid.

If it is an orthodox jade bone human demon refining method, refining the primordial infant-level xenomorph demon cultivation, with the blessing of the power of the xenomorph primordial infant, it can maintain the bone form.

Old Demon Pang thought about the words, urging the method of smelting the golden pill in the psychic puppet technique, and this thunder bone gradually began to thin, and the purple luster became deeper and deeper.

At the same time, the Yuan Spirit Array on the silver bone cornerstone was full of light, and a wave of spiritual light appeared, taking the initiative to wrap the thunder bone essence and include it in the runes of the Yuan Spirit Array.

The original layer of magic net turned into a blood-colored magic ball and returned to the body of Pang Lao Demon.

After absorbing the essence of the thunder spirit root, the silver bone suddenly had six purple marks containing thunder and lightning runes, which appeared on the arms, legs, chest, and back.

These six marks emitted a strong purple light, and the thunder attribute essence covering the silver bone seemed to be affected, and wanted to converge towards these six marks.

When Old Demon Pang saw these six marks, his face couldn't help but change, he flicked his ten fingers, and six blood-red silk threads shot out, hitting six thunder marks, scattering them as if they were dissolving a cow.

After the thunder seal shattered, it turned into several purple rays of light, submerged into the Yuan Spirit Circle on the bones, and the six blood threads turned into a magic net again, covering the whole body of the bones.

With the slightest trace of electric light, the magic net stripped a layer of thunder essence from the bones, and with a stabbing sound, the two dissolved into the air and turned into the essence of aura.

When Nie Wufeng saw this, he showed a little doubt, with his understanding of the psychic puppet and the Great Five Elements Technique, it was obvious that this skeleton also contained the power of the Thunder Spirit Root.

In this way, the power of the thunder spirit root is too strong, but it is not suitable, so Pang Lao Demon specially peeled off a part of it.

But isn't this bone a magic weapon? Even if it is a thunder attribute magic weapon, it cannot contain the power of the spiritual root of the immortal cultivator, unless this bone is the physical skeleton of the thunder spiritual root immortal cultivator.

But how could the bones of the human race reach the level of a magic weapon in the maturity stage.

Nie Wufeng was puzzled.

After seeing that the bone cornerstone was stable and the layer of thunder attribute essence on the surface was also attached to the Yuan Spirit Array, Old Demon Pang continued to cast the next step.

He used the same method to integrate the ice attribute spirit bone into it, and blessed a layer of ice crystal-colored spiritual light on the Yuan Spirit rune of the bone cornerstone.

"Nie Wufeng, the next is the most critical time, the dark spirit root is different from other alien spirit roots, and there will be fierce conflicts. ”

"The old man, as a great cultivator of the dark spirit root, can barely suppress it, but it is not safe, you need to control the wind attribute spiritual power in the center of the adjustment, and cooperate with the old man with the Great Five Elements Technique, so that the four spirit roots are compatible. ”

Nie Wufeng said without sadness or joy in his eyes: "Yes, senior." ”

Pang Lao Demon continued to cast spells, so that the bones of the dark spirit root combined with several demon path materials were fused together to the Yuan Ling rune, and the blood-colored magic net was not collected by him, and it was still shrouded in the Yuan Spirit Array.

And the silver bone cornerstone, it seems that because of the integration of the power of the dark spirit root, there is a great conflict between several forces, and the whole bone begins to tremble.

Old Demon Pang said in a deep voice: "Nie Wufeng, it's your turn." ”

A cyan flame shot out from the magic circle below, enveloping Nie Wufeng's body, and Old Demon Pang threw out several wind attribute materials at the same time, followed by the Yuan Infant Fire.

Nie Wufeng's body turned into a skeleton at a speed visible to the naked eye, and various materials were also burned into a little spiritual light, fusing with this cyan bone.

Old Demon Pang's expression was serious, and the magical aura in his body, which was equivalent to twice that of the Great Monk, was mobilized by him, and the terrifying magic power filled the secret room.

He wanted to suppress the xenomorph power that was about to explode on the bone cornerstone, and at the same time, he had to quickly refine Nie Wufeng into a wind attribute essence, if it weren't for his strong blood magic power, he really wouldn't be able to do this.

After only an hour, the wind attribute spirit bone was completely formed, turning into a thin layer of humanoid bone essence, close to the silver bone cornerstone.

"Nie Wufeng, you can now take the initiative to control your wind attribute essence, and the moment the old man takes away the magic net technique, it is the time for you to adjust the power of the alien species. ”

Feeling the fluctuation of Nie Wufeng's divine soul, Pang Lao's magic made a decisive move, and took away the blood demon net, and the cyan wind attribute essence was directly submerged into the surging Yuan Spirit rune.

"Boom!"

A huge explosion sounded, and the four attributes of wind, thunder, ice, and darkness collided violently as soon as they came into contact, although the explosion was loud, but the explosive power of the repulsion of different attributes was not transmitted, and it was directly absorbed by the silver bone cornerstone.

"The old man's method is really right, this bone cornerstone can easily withstand it. ”

Old Demon Pang's face was overjoyed, and he continued to pinch the magic decision, and the essence demonic qi of gold, wood, water, fire, earth, and pitch-black rose from the magic circle below, turning into six colors of spiritual light, and submerged into the cornerstone of the bone.

"Nie Wufeng, cooperate with the old man to reconcile the power of different species. ”

Old Demon Pang was pinching some kind of mystical magic in his hand, and the conflict of the power of different species began to ease under the adjustment of the aura and wind attributes of this magic circle.

Despite this, there was still an explosion sound coming from the bone cornerstone, and the strange forces generated by the explosions were all channeled into the silver bones, and there was not the slightest spillover of the power of the xenomorphs.

With the active cooperation of the wind attribute and the casting of Pang Lao Mo, the four different powers of wind, thunder, ice, and darkness began to slowly merge, and Nie Wufeng's divine soul fluctuations gradually disappeared.

One day, two days, until the third day.

The four xenomorphic powers were submerged in the Yuan Spirit Rune and disappeared, and the silver bones returned to their previous appearance, and it didn't seem to have changed at all.

Just when Old Demon Pang was a little puzzled, a powerful suction force suddenly came out from the silver bone, and the aura of the high-grade spirit stones in the magic circle rose to the sky, plus the true demon qi of the pure true demon water, all poured into the bone cornerstone.

Seeing this, Old Demon Pang finally showed a little excitement on his face, and he hurriedly took out a set of high-grade spirit stones and pure true demon water, and filled them into the magic circle, making the aura even more abundant.

After absorbing the aura of the bone foundation stone for three days and three nights, a layer of five-colored halo appeared on the bones of the two arms, and soon this halo was transmitted from the arm to the whole body, making the entire silver bone wrapped in the five-color halo, which was gorgeous and dazzling.

Suddenly, the various auras in the circle seemed to be guided by some kind of guidance, and they swirled outside the silver bones, forming an illusion of a golden giant ape.

This giant ape is extremely majestic, its arms are thicker than its thighs, it is extremely hideous, and its golden hair also has a layer of five-colored halo.
