It didn't take long for Xuantian to come to the front of the Flame Mountain Range, and the true scope was far greater than Xuantian had imagined.

In addition to the huge Flame Mountain in the center, there were also smaller Flame Peaks, a total of thirty-three, surrounded by the Central Flame Mountain, and there were dozens of miles in width.

And the Flame Mountain in the center, as high as three or four thousand meters, compared to the Heavenly Sword Peak, is only tall and not short, it is very majestic, especially the entire mountain peak is covered by raging flames, it looks much more steep and majestic than the Heavenly Sword Sect.

In the raging flames, from time to time, huge flames rose into the sky, extending more than 100 meters away, which was extremely amazing.

Xuantian was still hundreds of meters away from the Flame Mountain Range, but it already felt like a furnace, extremely hot.

"This flame all over the mountains, I don't know how much [Chapter 433] Earth-level Heavenly Fire (I) years have burned, what is burning? Is it inexhaustible?" Xuantian was shocked in his heart, the Flame Mountain Range in front of him was beyond common sense.

In ordinary flames, there is always fuel, and when the fuel is burned out, the flame is extinguished, but this mountain range, except for the rocks, there is nothing.

Suddenly, a flash of inspiration flashed in Xuantian's mind, and his expression was enlightened, "It's qi! Heaven and earth essence, heaven and earth aura, vitality, such a large area of flame mountain range, it can't be burned for a long time, what a heaven and earth essence of the entire land of Shenzhou is burned, what a waste of it! What a waste of it? No wonder the land of Shenzhou is unlucky, the supreme king is difficult to come out, the essence of heaven and earth of the entire land of Shenzhou is burned in vain, the aura of heaven and earth is nowhere to be seen, the vitality of heaven and earth is very thin, and there is a ghost's luck ......!"

As soon as he figured it out, Xuantian was stunned. It's such a waste.

Since the end of the ancient era, the heaven and the earth have changed, the aura is completely gone, the vitality is thin, and it is no longer suitable for martial artists to cultivate, if it is because of this flame mountain range, then. Hasn't this Flaming Mountain Range been around for nearly 10,000 years?

Such a large flaming mountain range has been burning continuously for 10,000 years, burning away the essence of heaven and earth. It is enough to cultivate thousands of supreme kings.

Difficult [Chapter 433] Ground-level Heavenly Fire (Upper) Dao Shenzhou is a large place with a circle of more than one million miles, a large land and rich resources, and outstanding people. The supreme king is rare to see for thousands of years, it turns out that thousands of supreme kings have been burned by this flaming mountain range.

Xuantian looked at the Flame Mountain Range in front of him, and couldn't help but rub his head, although he knew that this Flame Mountain Range had burned the essence of the land of Shenzhou, but Xuantian was helpless, and there were raging flames within a radius of dozens of miles. It can't be extinguished at all.

The flame mountain range within a radius of dozens of miles is connected into a whole, unless all the flames can be extinguished in an instant, the essence of heaven and earth is endless, as long as there are still flames. Where it is extinguished, it burns again.

To extinguish all the flames in an instant, you need to be able to slap it with one palm and cover all the flame mountains within a radius of dozens of miles, even if it is a supreme king, it is impossible to do it.

Xuantian flew forward, reaching the sky above the Flame Mountain Range. It's even hotter here, and even flames often come out of the void, and the powerhouses at the peak of the Earth Rank Realm are difficult to bear, but for Xuantian, who has a super perfect level fire attribute, the resistance of the flames is extraordinary, although it feels hot, there is no problem.

Suddenly, Xuantian's eyes lit up, and he saw a line of words from the huge flame mountain in the center: The Heavenly Fire King is here!

The Heavenly Fire King, the Supreme King of 4,000 years ago, actually came here.

Well!

Xuantian's expression moved, and not far from the inscription of 'Heavenly Fire King', there was an entrance to a cave.

In the cave above the Flame Mountain, the flames outside are already scorching enough, even the powerhouses in the late stage of the Earth Rank Realm are difficult to bear, and the flames inside the cave are not even more terrifying?

If there is a 'heavenly fire', it will be in the inner part of the mountain, and the essence of heaven and earth in the entire land of Shenzhou will be burned, if there is no 'heavenly fire', Xuantian will never believe it.

It's just that the only possible situation is that even if the 'Heavenly Fire King' came here four thousand years ago, then the 'Heavenly Fire' inside may have been taken away by him.

"In the inscription left by the 'Heavenly Fire King', he has called himself the 'Heavenly Fire King', it can be seen that when he came here, he was already the supreme king, and he should have little interest in the earth-level and heaven-level Tianhuo, only the king-level Tianhuo can make the supreme king tempted, as long as there is a ground-level 'Tianhuo', I still have hope to get it. "Xuantian said darkly.

Xuantian turned the true element in his body into the true fire of the earth element, enveloped the entire body, and then rushed directly into the cave, the flames in the cave were even hotter, even if Xuantian's resistance to the flames was extraordinary, he had to take some precautions.

There are flames everywhere in the cave, and the naked eye can't see much distance, Xuantian opened his eyes and pupils, and more than 100 meters in front of him, whether it is in the cave or in the mountain, he can see it clearly.

Xuantian walked in the flames, and the flames on his body were soaring, almost merging with the flames, like a fire god shuttling in the sea of fire.

"Wow...... Sure enough, there is a 'Heavenly Fire', Baohu Purple Fire, Seven Flame Red Lotus, and Phoenix Feather True Flame...... So many Xuan-level Heavenly Fires!" Xuantian entered the cave for hundreds of meters, and he saw a lot of 'Heavenly Fires'.

However, the Xuan-level 'Heavenly Fire' is the lowest-level Heavenly Fire, which has a huge effect on the martial artists of the Innate Realm, but for the earth-level powerhouses, it is like chicken ribs.

"Anyway, it's not too much to bring with you, it's good to have the opportunity to give it to others!" Xuantian took some Xuan-level Heavenly Fire, and with his current cultivation, he subdued Xuan-level Heavenly Fire in an instant.

After collecting seven or eight kinds of Xuan-level 'Heavenly Fire', Xuantian advanced more than a thousand meters in the cave, and a huge cave hall appeared in front of him.

There weren't too many flames in this cave hall, and the line of sight could be seen far away, but it was even hotter than the flames, and it was already in the center of the mountain.

The cave hall is nearly a kilometer in radius, and the first thing Xuantian saw was a few big words on the opposite wall: The northern wilderness is difficult to cross, I go east!

The handwriting was exactly the same as the one outside the cave, and Xuantian determined at a glance that it was left by the 'Heavenly Fire King'.

Although there are only eight words, "the northern wilderness is difficult to cross, I will go eastward" reveals a lot of information.

The Northern Wilderness should refer to the Beast Wilderness in the north, it seems that the 'Heavenly Fire King' has been to the Beast Wilderness, but even he has not been able to cross the Beast Wilderness and leave the land of Shenzhou.

Judging from these eight words, the 'Heavenly Fire King' wanted to leave the land of Shenzhou was very strong, and he couldn't leave through the beast famine, so he changed his direction and went to the east.

The supreme king is the only one in the land of China, he is invincible all over the world, and his life span is much longer than that of other warriors, enough to live to two hundred years old, when he is in the prime of his life, watching his friends and relatives of the same generation die one by one, it must be a bleak state of mind, after the age of 100, there is no one of the same generation, the second half of the life of the supreme king, is very lonely, at this time, leaving the land of Shenzhou, stepping into a higher martial arts realm, should be their only pursuit.

In the cave hall, Xuantian did not see the 'Heavenly Fire', however, in the center of the cave hall, there is an abyss with a radius of about 100 meters, and the flames are soaring inside, and the flames there are almost transparent, if there is a large area, it is difficult to see without looking carefully, and it is very close to the distorted air.

Xuantian was stunned, it was Tianyuan Ganghuo, the powerhouse of the Tianjie Realm, the Gangyuan in his body was burning, and he could turn into this kind of flame, although it was almost transparent, but the power was terrifying, compared to the earth-level 'Tianhuo', it was even better, and the powerhouse of the Earth-level Realm would die if he touched it.

"It's strange!There is a Xuan-level 'Heavenly Fire' in the cave, and there is a Tianyuangang Fire in the center of the cave hall, why don't you see the Earth-level flame?" Xuantian frowned.

There was a place where Tianyuan Ganghuo was, he couldn't go at all, only the periphery of this cave hall was the place where he set foot, but there was nothing.

"Oh! no!" Xuan Tian looked at the ground under his feet.

The ground is a crimson rock, this kind of stone, born with fire, no matter how it burns, it can't be burned, the whole mountain range is such stones, logically speaking, these stones, should be a whole piece, the flame cannot burn these stones.

However, most of the stones on the ground are whole, but some places are cracked, and each crack has a radius of more than ten meters, and the originally complete rocks have become small pieces of broken stone, and some even directly concave down, and a small cave has appeared.

It looks like something has come out of the ground.

Xuantian's spirit suddenly became vigilant, and he suddenly thought of a demon beast: the Devourer.

"Shouldn't there be a 'Devourer' coming in and devouring the earth-level 'Heavenly Fire'? Damn! How advanced does that have to be?"

Xuantian opened his pupil and carefully observed the rocks underground, and sure enough, the shattered rocks formed a passage, and there were indeed things passing under the rocks, because the rocks were only the difference between complete and broken, so even if Xuantian opened his pupils, he couldn't see it if he didn't look carefully.

There are many passages under the rocks, criss-crossed, and Xuantian walked forward along a passage, along the edge of the cave hall, and kept observing the underground.

Xuantian walked more than a hundred meters, and he didn't see any 'devourers'.

Click!

Suddenly, there was a cracking sound on the wall behind him, and Xuantian's back suddenly cooled.

Attacked!

The sword light in Xuantian's body flashed, and his body shot forward like lightning, rushing out more than a hundred meters in an instant, and turned around to look.

I saw that where he was standing just now, the rock shattered and recessed a meter or two.

In the wall more than 20 meters away, a huge head stretched out, chewing on a stone mountain stone in its mouth.

The skull was very long, connected to the long body, and it was a giant snake, but the head was completely different from a snake, to be precise, it was a huge worm.

It's the Demon Beast Devourer.

Because of eating too many rocks in the Flame Mountains, the skin of this 'Devourer' is exactly the same as the rock, no matter the color or texture, the shell of the 'Devourer' has completely transformed into a rock-like substance. rq！！！
