There is not only one refining room on Xuanzu Mountain, but all the refining rooms are all in the belly of Xuanzu Mountain. Through a naturally formed karst cave, Zhan Wusheng ran for a hundred and ten miles underground, feeling that the pressure of the underground world suddenly increased, as if entering a closed inflatable valve, and the gravity suddenly increased more than ten times, this change made Zhan Wusheng very surprised.

You must know that the gravity of the entire fairy world is more than a hundred times higher than that of the lower world, even with his strong body, when he first arrived in the fairy world, he couldn't adapt to it for a while, and it seems that the gravity here has increased more than ten times, which suddenly makes his movements more sluggish, and the muscles and muscles on his body are affected for a while, and he can't help but stop and adapt to the environment here.

It's a beehive-like place, with caves on top of the walls and no one leading anywhere. Zhan Wuming looked at the jade token in his hand, which was numbered thirty-seven, and his eyes fell on a cave engraved with the number thirty-seven on the cave wall, and it was estimated that it was the refining room he rented.

There are danxiang floating in many caves, and it is obvious that this underground space is not only a refining room, but also some alchemy rooms, however, there is no pill that needs to be refined in this environment, with his current cultivation and realm, the alchemy medicine is enough with his own natal fire. Even if it is an immortal-level fifth-grade elixir, his natal primordial fire is enough, but if he wants to melt the anti-heaven sword forged by this Canglong Reverse Scale, it will be too powerful, after all, the material of this Canglong Reverse Scale is too advanced, and if he doesn't borrow special means, he won't be able to integrate divine materials into it at all.

Cave No. 37, when you enter a few zhang, you will see a huge stone gate like a broken dragon stone blocking the way. Zhan Wuming was slightly stunned, and found that there was a prismatic dent on the stone door, and Zhan Wuming pressed the jade plate in his hand into the dent.

The "Buzz ......" jade plate coincided with the dent, emitting a pale cyan light, which spread to the stone gate in all directions with the dent as the center, instantly giving the entire stone gate a layer of brilliance.

The cave shook slightly, and the huge stone door slowly rose with a "babbling" sound. Under the boulder, all kinds of runes are engraved, and the runes are entangled, like dragons and tigers, as if a hundred beasts roar, and they are frightened when they see the battle.

This broken dragon stone is only afraid that the peak powerhouse of the Immortal Emperor can't do it if he wants to forcibly break it, that Dao rune is the law of heaven and earth, mysterious and weird, although the width of this stone gate is not more than a zhang, but it is enough to block thousands of horses and thousands of troops, and there must be a jade card to open.

For any piece of mountain stone in this underground cave, Zhan Wudi did not despise it in the slightest, you know, under this gravity that is more than ten times heavier than the fairy world, I am afraid that an ordinary stone is more than ten times heavier than the outside, and it is more than ten times stronger.

After entering the cave, the giant gate of the broken dragon stone closed again, and the battle was lifeless and went deep into a hundred zhang, and a platform with a radius of dozens of zhang appeared in front of him, and there was a small altar with no material lying on the platform, and a cluster of red flames in the center of the altar swayed like a beating elf.

The temperature of the entire platform rose suddenly, and the extremely rich fire element sprinkled the entire space.

"Is this the fire of the gods and demons?" Zhan Wusheng felt that something in his soul suddenly moved, and he actually gave birth to a trace of desire to devour.

Zhan Wuxing swallowed his saliva, he actually had the idea of wanting to swallow this flame, and at the moment when this thought was born, the flame on the altar suddenly changed, and turned into a beast shape, like a dragon and a tiger, and a violent aura suddenly rushed towards Zhan Wusheng!

"Damn, it won't be!" Zhan Wusheng scolded secretly, his body flashed, and the breath slammed heavily on the cave wall, making a roar.

Then the flame reverted to its original form, dancing on the altar, as if it had a little more contempt for the battle of lifelessness. This made Zhan Wuming a little depressed, this flame could actually feel his inner thoughts, and he could actually transform into an attack, this was no longer an ordinary flame, it was more spiritual than Zhan Wusheng's immortal flames.

Those flames that are lifeless only have the fire spirit of the Qingying Immortal Flame and have their own consciousness, and the others are all destroyed by Xuanwu, although they are still immortal flames, but the soul is chaotic, and naturally they cannot be compared with the Qingying Immortal Flame.

The flame in front of him was more spiritual than the Green Immortal Flame.

"I have no ill will towards you!" said Zhan Wufang.

The Taixu God decided to reveal the power of the fire spirit in his body, and the power of other elements quickly disappeared in the Soul Cave Heaven, and the power of the Fire Element Cave Heaven erupted, and a faint layer of green flames rose from the body of the lifeless battle, turning into the body of the fire spirit.

The flame on the altar seemed to be stunned, and looked at Zhan Wusheng suspiciously, jumping on the altar with a little restlessness, and then becoming cheerful again, showing closeness to the body of the fire spirit of Zhan Wu.

Zhan Wusheng breathed a sigh of relief, he still had to count on this flame to refine his weapon, if he made each other hostile from the beginning, don't refine it for himself.

Zhan Wuming conveyed the kindness of his thoughts, and slowly approached the altar, he felt that the temperature of the flame was comfortable.

"I need to sacrifice this sword. Zhan Wuxuan pulled out the anti-heaven sword, and a slightly panicked mood swing came out from the sword body, and the sword spirit seemed to mean something, and was a little afraid of the flames in front of him.

Zhan Wusheng stroked the Heaven Defying Sword, and the divine soul calmed the throbbing of the sword spirit, and then the sword spirit seemed to be excited. He jumped into the flames.

"......Boom" The flame suddenly became vigorous, like a giant python entangled the anti-heaven sword into it, and a huge flame erupted from the altar, like an exploding crater, with a trace of black light, as if it was about to burn through the void.

The altar burst out with a huge milky white aura at this time, wrapping the flames that rose into the sky, like a huge milky white furnace, through the almost transparent milky white brilliance, you can see the flames at the mouth of the altar rushing into the sky, like thousands of roaring and rushing beasts rushing into the milky white light cover furnace, disturbing the air flow in the void, a terrifying high heat makes the entire platform have a feeling of being roasted.

The Heaven Defying Sword let out a soft roar in the flames, and after the sound of the dragon's roar, it was like a small dragon that broke out of its shell, constantly swimming in the flames, and to the surprise of Zhan Wusheng, this little dragon did not resist the terrifying flames in the slightest, and even like a fish entering the water, extremely happy. The fiery beasts that kept rushing out of the altar seemed to have become the rations of the Heaven Defying Sword, constantly devouring, constantly absorbing, as if it were a bottomless pit, devouring the endless flames.

Seeing this scene, Zhan Wuming was stunned, he originally wanted to use this god and demon earth fire to refine the anti-heaven sword, and integrate other immortal materials into it, he never thought that this anti-heaven sword drilled into the fire of the gods and demons, and actually began to devour the massive flames, the sword body seemed to slowly grow in the process of devouring, and the breath became stronger and stronger, as if as long as he devoured this endless earth fire, his level could be continuously improved, which made Zhan Wuming very speechless.

The Sword Spirit of the Anti-Heaven Sword is connected to the soul of Zhan Wusheng, and Zhan Wusheng can naturally feel his emotions, and even feel the strange changes of the Anti-Heaven Sword. In the gods and demons earth fire, there is not only a simple fire element, but the fire element has a trace of divinity, and it is precisely because of this trace of divinity that the cluster of fire spirits has its own consciousness, even higher than the evolution level of the green immortal flame, and can even understand the will of the battle without life.

I didn't know that in other refining rooms, those people who wanted to sacrifice weapons had to sacrifice spiritual objects to this altar first, and then they could ask this fire spirit to help refine the weapon. If there was no sacrifice, this earth fire would not be able to be activated at all, even if it was an old monster of the Immortal Venerable Rank.

Zhan Wusheng didn't know this rule at all, and after he incarnated into the body of the fire spirit, he immediately got the approval of the fire spirit, which saved even the sacrifice and induced the earth fire.

The gods and demons were originally going to be powerful in refining the Heaven Defying Sword, but they didn't expect that all the fire spirit beasts that were transformed from the fire energy that erupted from the ground were swallowed by the Sky Sword and turned into the energy of the Sky Sword.

The Heaven Defying Sword was like a coiled dragon, swimming in the huge milky white void furnace, more like a fierce shark hunting in the deep sea, preying on every fire spirit that erupted with the earth fire.

Zhan Wusheng suddenly thought of a question, this Canglong Reverse Scale is a divine object on Cang Yu's body, Cang Yu was originally the patriarch of the Chiyan Divine Dragon clan, the Red Flame Divine Dragon is the dragon of the Fire God, and the devouring of the fire of the gods and demons by this Anti-Heaven Sword is not an accident.

Zhan Wufang has never figured out the evolution path of his anti-heaven sword, the evolution path of this sword is not the same as other immortal weapons, it needs to be continuously integrated into new materials, his anti-heaven sword was originally forged by a rare divine material between heaven and earth, he is cast by the anti-scale of the god-king level dragon clan, as long as he uses some means, he will continue to stimulate the potential of this anti-scale, so that his divinity can be restored, and the level of the anti-sky sword will naturally be improved.

The origin power of fire between heaven and earth is exactly what the Chiyan Shenlong clan needs, and it is also the nutrient for the continuous evolution of the Anti-Heaven Sword, of course, not all flames have such an effect, but the god-demon earth fire in front of him is exactly what the Anti-Heaven Sword likes.

The fire of the gods and demons is the flame that is drawn from the center of the earth of the gods and demons battlefield space, it can be said that it is the fire of the center of the entire gods and demons battlefield, and Xuanzu Mountain is a miracle, a demarcation point that exists in the middle of the fairy realm continent and the gods and demons battlefield in another space. Just as I saw when I came to Zhan Wudi, Xuanzu Mountain seemed to be half in the Immortal Realm Continent, half in the Gods and Demons Battlefield, and that part of the Gods and Demons Battlefield was where the enchantment of Gonghua Immortal Mansion was located, and this Gods and Demons Earth Fire had already entered the underground of Gonghua Immortal Mansion.

The most important thing is that this god and demon earth fire is definitely not an ordinary flame, and under the ground of the god and demon battlefield, there is a backlog of too many gods and demons when gods and demons are fighting. In the battlefield of gods and demons, sometimes they will break through the earth to form death waves, which shows how abundant the power of gods and demons is underground.

Because of this, the power of the gods and demons has been completely integrated into the underground lava of the gods and demons continent, so that the nature of the underground lava is also constantly changing, generating powerful divine power, and this earth fire with divinity, although it is not called fairy flame, but it is not weaker than fairy flame, and more importantly, it is inexhaustible.
