The Endless Fire Domain, which has been burning since it was discovered, is so vast that it seems endless.

This is, of course, false, endless, just not by orders of magnitude.

It's not that no one has explored this place, but the flames in this endless fire realm, not mortal fire.

Its temperature is extremely high, and it is even rumored that there is an immortal fire in the core of the Fire Domain, which once burned an immortal to death!

After seeing this information, Zhang Xuan came to this Endless Fire Domain alone, the immortal of this world is the Red Dust Immortal, and he is the strongest under the Immortal Domain.

The flame that can burn the immortals, as well as this flame that will never be extinguished, Zhang Xuan naturally wants to come over and take a look, so as to pass some boring time.

In the air, there was a scorching stench, which was the smell of underground magma.

The earth cracked, and red magma flowed through the cracks, like blood vessels.

The outermost thing is just a fire, and although the place is hot, there are still amazing flora and fauna. Survive here, but their aura content is extremely low, and they can't be used in medicine.

Inside, there was a blazing flame, which was extremely hot, and there were large swaths of flames in the air, like the wind, covering the sky and making it impossible to hide.

This kind of flame that can burn the monk, Zhang Xuan doesn't feel anything, he has already made a subspace layer on his body, and the flame can't burn him at all.

In this Endless Fire Domain, it is rumored that there are ten types of flames, each of which is extremely powerful, and the closer it is to the center, the more powerful the flame becomes.

Rumors are not spread without any evidence, if the flame in this can burn through the space, then the credibility of the rumors will be satisfactory.

The further you go, the higher the temperature, the color of the flame also changes, the red fire becomes cyan fire, and then it becomes blue fire.

And in this blue flame, Zhang Xuan also found that there were people here, with the help of the heat of the divine fire, to melt immortal materials, forge magic weapons, and some people were holding the Dan furnace to refine medicine.

"Boring, this flame is even cooler than the flame in the center of the earth, how good can the magic weapon be made?"

Zhang Xuan's vision is high, so he naturally doesn't look down on these.

He has already hooked up the leylines in the Seven Hundred Lakes, and those refiners can use the Earth's Core Molten Fire to create weapons, armor,

Under Li Xiaoman's arrangement, these assembly lines are running well

continued to walk inside, but it was a black flame, this kind of flame carried black gas, which reminded Zhang Xuan of sunspots, this kind of flame is also black.

Coming out of the subspace, Zhang Xuan did not smell the earthly evil qi, but a mixed supreme yang qi.

Reaching out and grabbing it, the black flame fell into Zhang Xuan's hand like ash at the bottom of the pot.

"The temperature is good, after all, it feels like a mud bath, if it is thicker, it is the same as a mud bath, but you can bathe in it and completely refine the heart of the demon emperor!"

Zhang Xuan was very satisfied with this place, and found a place where the black fire was strong, Zhang Xuan went in to swim, these flames were thick, and they were like oil, and they could swim in it.

At the chest, the supreme bone slowly floated up, running Zhang Xuan's qi and blood with all his might,

And in the sea of suffering, the Demon Emperor's heart kept trembling, it had been refined by Zhang Xuan, and now it was only the size of a finger.

After several days of meditation, Zhang Xuan finished refining the heart of the Demon Emperor.

At this time, his skills have completely entered the realm of turning into a dragon, and in this world, Zhang Xuan's body has been exercised, and he can realize the Tao with peace of mind.

But Zhang Xuan's perception was already at the stage of a saint, and he already knew all the avenues, but he felt that this physical body was not strong enough, and the accumulation of divine consciousness was not enough.

"After being in the dragon realm, I won't be able to exercise, but I want to continue forging and see the limit of this world's body refining method!"

Zhang Xuan thought about it, so he continued to walk inside, this was the fifth fire domain, it was a golden space, about twice as hot as the black fire.

The space here has been blurred by the high heat, and the space is fragile, like a layer of sugar coating, only a slight movement, the space will break apart, and then flow away by itself.

The sixth layer of the fire domain is a piece of light purple, and the space here has been burned through, like gauze, with tiny holes, but these holes are squeezed and healed by the space, refracting a strange purple light.

The flames here not only burn through the space, but also burn the divine sense.

Consciousness is a strange particle and waveform, and when it is strongly disturbed, it loses a part of the wave and particle.

Zhang Xuan is just a wisp of divine consciousness in his body, and although he has grown and become stronger again, he has not yet reached the level of a saint.

It's just that the spiritual power enters the seventh sense, which can hook up the universe.

He couldn't use his divine sense to explore this purple fire domain, but he already had some ideas about it, but he hadn't verified it yet.

The nine colors of this fire domain are hotter the further you go, and the hottest under the sky is the true fire of the sun.

Emperor Jun, Eastern Emperor Taiyi, Rulai, all those who cultivate are the true fire of the sun.

So Zhang Xuan strolled forward and continued inside.

Sure enough, the innermost layer was already pure white.

The speed of the flame is the same as that of lightning, but the form is much more docile than that of lightning.

And in this piece of blazing white, there is a jade seal suspended in it,

There are nine coiling dragons on this jade seal, antique, and it can be under the true fire of the sun, there is no abnormality at all, this jade seal must have its uniqueness!

As soon as Zhang Xuan beckoned, the jade seal was still struggling, as if he wanted to leave here, but Zhang Xuan had already blocked the space, and this jade seal had no way to go, so it could only fall into Zhang Xuan's hands.

"I didn't expect there to be a sanity inside!"

Zhang Xuan smiled, and the thunder law in his hand exploded, and he destroyed this divine intelligence, after all, this divine wisdom was not cultivated by him, and it would not completely obey Zhang Xuan's wishes.

"Boom!"

Lei Fa broke out, the jade seal had returned to the ownerless transformation, and Zhang Xuan laid the imprint of divine consciousness, and at this time the jade seal completely obeyed Zhang Xuan.

At the same time, an invisible fluctuation came out from the jade seal.

In the Ancient Forbidden Land, in the abyss surrounded by the Divine Mountain, nine huge dragon corpses suddenly hissed, and it seemed that there were similar species appearing in the world, and they cheered and cheered.

In the holy land of the Jiang family, the Hengyu furnace, which had been sleeping for many years, suddenly vibrate, and wisps of divine fire broke out, and the powerful power of the imperial soldiers suddenly alarmed the clansmen!

On the cold moon peak of the Ji family, the Void Mirror suddenly reflected its brilliance, and countless divine lights burst out, tearing apart the starry sky! This vision made the elders of the Ji family panic.

In the Holy Land of Yaochi, the earth trembled, the peaches swayed non-stop, and their Imperial Soldier Immortal Tears Green Golden Pagoda kept jumping, as if they were going to compete with something!

Yan Ruyu was bitter and bitter, her Qinglian Emperor soldiers hissed, and they were about to break through the shackles and fly into the distance, the strangeness of the imperial soldiers made everyone feel uneasy.

The Great Elder hurriedly closed the big array, and only then did he isolate the breath, and the Qinglian Emperor soldiers lost their target, so they calmed down.

Zhang Xuan didn't know anything about these and didn't bother to know.
