Immortal Divine Material. It is the divine material for the exclusive cultivation of the Extreme Dao Holy Weapon for the Extreme Dao Saints, which is rare in the world, and it has not been obtained by searching all over the heavens and the earth.

In the ancient times, not every Extreme Dao Saint was able to refine his own Extreme Dao Holy Weapon, because immortal divine materials were too difficult to find.

I have to say that Gu Fei's luck is so good that even the heavens are jealous.

The Nine Heavens Star Iron is a divine material in the extraterritorial starry sky, and it is difficult to find this kind of divine material if there are extreme saints who go up and down for nine days and fall into the nine shadows.

However, Gu Fei had obtained a mountain peak that was completely formed by the Iron of the Nine Heavens and Stars.

At this time, Gu Fei felt that it was time to refine his weapons, everything was ready and only the east wind was owed, and now he even had immortal divine materials, and he had obtained the true yang phoenix marrow in the land of phoenix fall.

The True Yang Fire can smelt all things in heaven and earth, and it is also the exclusive refining divine fire of the Extreme Dao Saint.

The dragon yuan bred by the dragon qi of the earth, and the phoenix marrow bred by the land of the phoenix, one yin and one yang, the two converge, and they can interweave the avenue of heaven and earth, and the black sky can use these two heaven and earth treasures to regenerate his flesh and blood.

However, Gu Fei wanted to use the True Yang Fire to quench the Nine Heavens Star Iron, so Heitian had to wait for a while.

"I want to sacrifice my own Extreme Path Saint Soldier!" Gu Frisbee sat at the highest place in this divine land, and he had already made up his mind in his heart.

"Buzz!"

The mountain and river tripod shook, and under Gu Fei's urging, the mountain and river tripod suspended in front of Gu Fei spit out two divine beads, each of which was only the size of a fist.

A divine bead of divine flame swirled around, revealing endless heat, even if it was blocked by chaotic Hongmeng Qi, it still made Gu Fei feel hot, and the blood in his body was about to boil and burn.

The other divine bead is a dragon qi surging, and there seems to be a small dragon shadow like an earthworm swimming on it, and the dragon qi of the earth is mighty.

The divine bead containing the essence of the dragon and the phoenix can be big and small, and it has not been refined, it is already so miraculous, if it is refined, it must be a supreme holy weapon.

The breath exuded by the dragon yuan phoenix marrow, centered on the mountains and rivers, surged out in all directions, and soon spread throughout the entire divine land.

"Are you going to start?"

On top of a spiritual peak, Xiao Qing swallowed the dragon ball suspended in front of him into his stomach in one gulp, and then turned his head to look in the direction where Gu Fei was.

"Dragon Yuan Phoenix ......"

Next to the Divine Spring, the Yin and Yang Divine Diagram on Hei Tian's body continued to loom, and the soul fire in the skull was beating, revealing powerful soul fluctuations.

"Roar!"

A low roar came from a blazing valley, and a huge red unicorn like a hill stood up, bathed in the monstrous flames.

"The Lord ......"

In the distance, in a mountain range shrouded in a thick dead air, three terrifying figures rushed out, and in the mountains, a terrifying roar was heard, like a group of ghosts screaming, which made people's hearts palpitate.

The breath of the dragon and phoenix marrow unsettled the dead creatures.

Gu Fei began to refine the immortal divine material Nine Heavens Star Iron, which alarmed the living beings in the entire divine land, and under the breath of the mountains and rivers and the dragon and phoenix, no one did not change color.

"Boom ......"

At this time, a black hill rose from the mountains and rivers, and then was fixed by Gu Fei between the Phoenix Marrow Divine Bead and the Dragon Yuan Divine Bead.

This can allow Gu Fei to control the fire very well, if the True Yang Divine Fire emitted by the Phoenix Marrow Divine Bead is too powerful, it can attract the Dragon Yuan Essence Qi to offset the True Yang Divine Fire.

Moreover, under the tempering of these two essences, it is not certain that the Nine Heavens Star Iron may initially interweave the lines of the Great Dao.

Long Yuan and Phoenix marrow, yin and yang essence, the two qi are intertwined, can evolve the heaven and earth, the most unpredictable, in ancient times, there was a big man, cultivating yin and yang, swallowing the sun and the moon, and finally became an invincible pole saint in the sky and on the ground.

"Boom!"

The fist-sized phoenix marrow divine bead emitted a monstrous fire, and Gu Fei attracted the power of the divine bead, attracting the true yang divine fire, and refining the Nine Heavens Star Iron.

"Boom ......"

As soon as the True Yang Divine Fire pounced on the hill formed by the Nine Heavens Star Iron, the entire hill shook, and under the smelting of the True Yang Divine Fire, although the Nine Heavens Star Iron was shaking, the surface of the hill did not seem to react at all.

If it was an ordinary divine iron, I am afraid that it would have turned into ashes under the true yang divine fire a long time ago.

"Sure enough, it is worthy of being an immortal divine material!" Gu Fei thought to himself, the Nine Heavens Star Iron was the exclusive refining weapon of the Extreme Dao Saint, and even the True Yang Divine Fire was difficult to smelt for a while.

Smelting the Nine Heavens Star Iron is not an easy task.

Gu Fei was already mentally prepared, and he didn't expect to be able to smelt the Nine Heavens and Stars into a liquid state all at once, although it would take a long time.

Above the mountain peak, the divine fire was mighty, and the heat surged out in all directions, and the trees on the mountain peak gradually withered and yellowed and lost their vitality.

The chaotic Hongmeng qi emitted from the top of the mountains and rivers had weakened the heat emitted by the True Yang Divine Fire to the greatest extent, but the vicinity of the mountain peak where Gu Fei was located was still affected.

At the top of the mountain, it seemed that a dazzling sun had appeared, and the power of the true yang was so vast that even the chaotic Hongmeng qi could not completely isolate the fluctuations that emanated from this power of the supreme yang and the yang.

One hour, two hours, three hours......

One day, two days, three days......

Half a month has passed in the blink of an eye, and the dazzling brilliance above the mountain peak has not disappeared, but has become stronger and stronger.

Those who have cultivated the Heavenly Eye will also find that between the two groups of Shenhua, there is a black hill floating and sinking.

On the pitch-black hill, something reddish-brown had already appeared, which was the impurities contained in the hill that had been smelted out.

Even an immortal divine material like the Nine Heavens Star Iron is also impurity, not absolutely pure.

For half a month, the True Yang Fire has been continuously scorching this hill formed by the Nine Heavens Star Iron, but there is still no movement in this Nine Heavens Star Iron.

"Could it be that even the True Yang Fire can't smelt the Nine Heavens Star Iron?" Gu Fei couldn't help but feel a little surprised, the True Yang Fire, smelting all things, is the refining weapon divine fire exclusive to the Extreme Dao Saint, how could it not smelt the Nine Heavens Star Iron?

"It seems that we have to raise this divine fire to the extreme!"

If this divine fire is graded, the True Yang Fire can be divided into nine levels, and what Gu Fei is using now is at most about three levels of divine fire, this kind of Cheng Dù's divine fire is difficult to smelt the Nine Heavens Star Iron.

Only by truly making the Phoenix Marrow Divine Bead show its ultimate power can the True Yang Fire be elevated to that kind of invisible, almost void-like Extreme Divine Fire.

The divine fire is gradually raised, and the vitality consumed is also doubled, but fortunately, Gu Fei's divine power is endless, and the vitality is like a vast sea, and he is not afraid of the exhaustion of the vitality at all.

Gu Fei then began to trigger the power of the Phoenix Marrow Divine Bead step by step, and within the Phoenix Marrow Divine Bead, a powerful breath of life began to emanate, as if a sleeping phoenix had woken up.

Inside the Divine Pearl, you can vaguely see a phoenix reborn in the fire.

"The phoenix's divine power has been stimulated!"

Next to the Divine Spring, Hei Tian was moved again, he woke up from his cultivation state, and then stood up from the ground and looked in the direction where Gu Fei was.

The breath of the divine beast phoenix was vast in the divine land, making the creatures in the entire divine land tremble, even Xiaoqing and Balon had to change color.

A phoenix chirp sounded in the sky above the mountain peak where Gu Fei was, and above the round of "sun" above the mountain peak, a divine bird rushed out and circled and flew around the "sun".

The breath of the phoenix is strong to the extreme.

It was not a real divine beast phoenix, but a phantom shadow formed by the essence of the phoenix, but it was like the Nine Heavens Phoenix descending, and everything in heaven and earth trembled.

The phoenix soared, the divine fire burned the sky, and the divine fire that came out of the phoenix phantom had already taken on a translucent form, and the boundless heat was mighty, and the void was about to be burned to collapse and crack.

"Buzz!"

The mountains and rivers shook again and again, and the chaotic Hongmeng Qi sealed all directions, suppressing a void heaven and earth, even so, the trees and flowers on the entire mountain peak had already died.

On the top of the mountain, it was already bare, all the trees had turned into dust and scattered on the ground, and the stones were scorched and cracked by the heat emitted by the True Yang Divine Fire.

At this time, although Gu Fei had already hooked the power of the inner heaven and earth to block the heat emitted by the True Yang Divine Fire, he was still sweating profusely, as if he had just crawled out of the water.

The Phoenix Marrow Divine Bead emitted a thousand zhang divine light, but the Dragon Yuan Divine Bead was dim, Gu Fei did not stimulate the power of the Dragon Yuan Divine Bead, and now is not the time.

On the top of the mountain, the vision of the phoenix soaring lasted for half a month before the phoenix disappeared, and at this time, the black mountain formed by the iron of the nine heavens and stars finally changed.

The surface of the Black Mountain has melted into a black paste, but the entire Black Mountain has not completely melted into a liquid state, and has not been able to shape the vessel.

Over the past month, Gu Fei has been continuously improving the power of the True Yang Fire, but on the other hand, he is thinking about what kind of divine weapon he will refine this piece of Nine Heavens Star Iron, which is as big as a mountain.

Bells, seals, tripods, swords, knives, mirrors, sticks, towers...... The shapes of all kinds of utensils are constantly appearing in Gu Fei's mind, and in the cultivation world, ordinary monks like to sacrifice and practice magic weapons such as tripods, bells, and towers.

Therefore, most of the cultivators, the supernatural powers, the magic weapons they use are these kinds of magic weapons.

However, Gu Fei is not a cultivator, nor is he a supernatural person, and the utensils in the shape of dings, bells, and towers are not suitable for him, he wants to sacrifice martial arts and divine weapons, not any immortal artifacts.

"Sword! Yes, it's a sword, the sword is the ancestor of a hundred soldiers, let's refine the sword! Just refine a Nine Heavens Star Sword!" Gu Fei finally decided to refine the Nine Heavens Star Iron into a holy sword.

The Nine Heavens Star Sword, the name alone is already extraordinary, and Gu Fei is looking forward to it, because this is the divine weapon he has cultivated.
