Seeing this, the fire spirit explained to Dao Wuya, "In this geocentric flame country, there are strict hierarchies, and most of them are distinguished by imprints. There are seven levels: Gold, White, Blue, Green, Purple, Cyan, and Red. ”

"I didn't expect the level of Yin Yang Xuan Ice and Fire to be so high. "There is no end to the road.

In the face of such a huge momentum outside the city walls, Dao Wuya chose to keep a low profile, letting the various flame guards continue to maintain order, and quietly left in a look of shock.

After entering the city wall, the scenery changed greatly. The fire aura here is more intense, and the flowing magma earth fire is of higher quality.

As for the fire spirit beasts, they seem to be more intelligent. There are some buildings not far away, which seem to be somewhat similar to those of the Terrans.

"Fire Elf, what grade does the black mark belong to?" Dao Wuya asked suddenly.

"Black!" the fire elf was slightly surprised when he heard this, "This is a forbidden fire, it is regarded as a heresy in the Earth Center Flame Country! I remember that in tens of thousands of years, there was a black fire, and the fire burned nearly one-tenth of the territory of the Earth Heart Flame Country, but it seems to have been strangled in the end!"

"However, the second on the list of different fires is the Forbidden Black Flame, I wonder if this strange fire is what you call the forbidden fire?" asked Dao Wuya as he manipulated the Yin Yang Xuan Ice Fire to continue diving.

"I'm afraid you don't know the origin of the Forbidden Black Flame, right? The Forbidden Black Flame is the result of countless souls condensed over countless years, and it is a strange soul fire, the so-called Forbidden Black Flame, which specializes in the soul!" the Fire Spirit explained.

"However, it is said that there is not only one Forbidden Black Flame in the Immortal Cultivation Realm! Although the conditions for the formation of the Forbidden Black Flame are extremely harsh, there have been countless eras in the Immortal Cultivation Realm, and there are quite a few Endless Soul Lands alone!" the Fire Spirit added.

Dao Wuya controlled the Yin Yang Xuanbing Fire to transform into the appearance of the fire spirit beast here, and slowly approached the alien fire according to the guidance of the fire spirit.

"I didn't expect it to be the Burning Sky Flame that ranked ninth on the Alien Fire List!" the fire elf showed a hint of joy.

Dao Wuya and his party had already come to the depths of fifteen thousand zhang in the center of the earth, and during this time, the Burning Sky Flame had actually slowed down some distance.

"Wait!" When Dao Wuyan arrived near the Burning Sky Flame, he realized that the Burning Sky Flame had been restrained!

In front of him was a team of hundreds of fire spirit beasts, and the fire spirit beasts in the lead had turned into human form!

The Burning Sky Flame had already been packed into a bottle, and was held in the hands of the humanoid fire spirit beast led by it.

However, the Burning Sky Flame was not honest in that bottle, jumping up and down, and the originally transparent bottle had been burned red!

"The Burning Sky Flame is one of the treasures of the Earth Flame Country. The characteristic of the Burning Sky Flame is that it is extremely high, and it is said that the temperature at the peak of the Burning Sky Flame can rival that of the Lord of the Earth Core Flame Country!" The fire spirit began to manipulate the Yin and Yang Xuan Ice and Fire, hiding behind a green rocky reef.

This green rocky reef looks like a rocky reef in ordinary seawater, but it is actually formed by the hot fire of the earth's core!

"What to do? They're going to take the Burning Sky Flame away. If there is a fight in this place, it will definitely attract the attention of the Geocentric Flame Country. The fire elf said.

"I didn't expect you to know so much about the Earth Flame Country. Dao Wuya said with a smile, but he didn't continue to delve into the secret of the fire elf, so the fire elf also breathed a sigh of relief, "You can try to combine the breath of yin and yang Xuan ice and fire to secretly attract the Burning Sky Flame!"

"I'll try. The fire elf said.

Dao Wuya slowly approached this fire spirit beast team from another path, taking advantage of the rocky reef and other terrain.

Suddenly, the humanoid fire spirit beast suddenly trembled in his hands, and the Burning Sky Flame in the original bottle suddenly burned violently, and the intense high temperature caused the temperature of the bottle to rise suddenly.

"I didn't expect that this Burning Sky Flame had already formed some spiritual intelligence, and it asked us to save it. The fire elf said.

"How do you get close?" said the trail.

At this time, Yun Xiangsui suddenly said, "Master, you can completely drive the Dao Sutra, slowly approach, collect the Burning Sky Flame, and then slip away!"

"However, it takes a lot of spiritual power to drive the Dao Sutra. Dao Wuya frowned slightly.

"Master, don't forget, we are in the middle of the earth's fire, surrounded by boundless fire aura, you can use the fire aura around you to drive. Yun Xiangsui reminded.

At this time, Dao Wuya suddenly remembered the word formula derived from Dao Zhu: "Reiki, Lingye; ”

Although he has a variety of spiritual root qualifications, the spiritual power derived from his body with the help of the Dao Sutra is golden spiritual power, and this spiritual power obviously surpasses the statement about spiritual roots in the immortal cultivation world.

Suddenly, Dao Wuya had a new epiphany of Dao Zhu Words! Fire Spiritual Qi is a branch of Spiritual Qi, and his golden spiritual power is above all Spiritual Qi.

Since he could use the golden spiritual power, he could naturally absorb and use any of the five elements spiritual energy!

Thinking about it like this, Dao Wuya escaped into the Dao Sutra space with Yin Yang Xuan, Ice Fire, and Fire Spirits. At this time, an invisible and colorless Dao bead slowly moved forward!

Sure enough, Dao Wuya can use the endless fire aura around him to control Dao Zhu!

This endless fire in the center of the earth is actually equivalent to the boundless sea of fire aura!

However, Dao Wuyan obviously can't drive the Dao Sutra at will above the surface, after all, there is no such rich and endless aura on the surface at all!

The movement of the Burning Sky Flame in the bottle became farther and farther away, so that the bottle that had become red swayed from side to side. The humanoid fire spirit beast shouted angrily, and took out a green talisman seal and pasted it on the red bottle, and the shaking caused by the burning sky flame was much slighter.

There was an icy aura flowing in this green talisman, which was incompatible with the endless flames around it!

At this time, Dao Wuya had already come to the side of the humanoid fire spirit beast with Dao Zhu.

Suddenly, another group of fire spirit beasts appeared out of thin air, led by several humanoid spirit beasts.

A humanoid spirit beast on the opposite side said, "Centurion, have you ever seen the thirteenth prince Bai Ze?"

The humanoid spirit beast holding the Burning Sky Flame in his hand said, "Returning to the Thousand Commanders, I have never seen it, and I have come to capture the fleeing Burning Sky Flame in the name of the city lord." Time is pressing, we have recovered it, and we will quit!"

Hearing this, the commander led a team of fire spirit beasts to continue upward.

The centurion was about to move forward, when he suddenly saw that his hands were empty, and he was shocked and shouted: "Where is the burning sky?"

The humanoid fire spirit beast was furious, frowning and asking hundreds of subordinates. Hundreds of fire spirit beasts looked at each other together, and they didn't know what to do.

The Burning Sky Flame seems to have disappeared out of thin air!

And no matter how angry the humanoid fire spirit beast was, Dao Wuya took the treasure bottle and secretly rejoiced, and was already ready to leave, when suddenly the mountains shook!

A huge and long black pillar appeared out of thin air, almost startling Dao Wuya.

As soon as the huge and long black giant pillar appeared, it directly shook all the nearby centurions and earth spirit beasts to death!

Dao Wuya was shocked, if he hadn't entered the Dao Sutra, wouldn't he have been killed by this inexplicable thing! After all, that centurion's cultivation was comparable to the late stage of the Spirit Mountain Realm!

After this black giant pillar descended here, it continued to swell, not only becoming extremely thick, but also extending upwards and downwards!

At this moment, hundreds of seals flickering on the black giant pillar suddenly lit up, preventing it from changing. The black giant pillar and the seal started some kind of battle, and the liquid boiled in the flames of the center of the earth, and a violent whirlwind was generated around it!

Suddenly, Dao Wuya had a strange idea, that is, to put this black giant pillar into the Dao Sutra space.

In this way, with a thought, the black giant pillar was suddenly incorporated into the Dao scripture space!

"Huh?" Dao Wuyan didn't expect to get this black giant pillar so easily!

The black giant pillar actually went straight to the soul space of the Dao Sutra in the Dao Sutra and turned into a piece of fragments!

When this fragment slowly fell into the soul sky, the big ghost and the two ghosts suddenly knelt down!

"Big ghost and two ghosts, what is this?" asked Dao Wuyan, puzzled.

What made him curious was why this black giant pillar had fallen into the Dao Sutra Soul Air and turned into such an inconspicuous fragment!

What is the use of this fragment?

What made Dao Wuya even more shocking was that the hundreds of seals wrapped in the black giant pillar had all disappeared!

After inquiry, the big ghost and the two ghosts didn't know what this thing was, and kneeling down to worship this thing was an instinct in the bloodline!

Dao Wuya fell into deep thought. Obviously, this is some kind of treasure of the Soul Clan! Just such a fragment has already killed the centurion and the others with his breath in the center of the earth, what kind of divine power will it have if it is a complete artifact!

Dao Wuya held this thing in his hand, and felt very ordinary and ordinary, it was hard to imagine that this thing could show its might in the outside world!

Dao Wuya studied for a long time, but there was no result, and said, "Big ghost, this will reward you, I usually have time to study it!"

"Master, do you really want to give it to me?" the big ghost asked more than three times when he saw this.

When Dao Wuya handed this piece into the hands of the big ghost, the big ghost trembled and caught it, and said three times in a row, "Master, really give it to me! Master, really give it to me! Master, really ......."

This piece of fragment fell into the hands of the big ghost and immediately turned into a long hook, and when the big ghost waved, the momentum of the big ghost increased several times, directly crushing the little ghost!

On weekdays, the big ghost and the little ghost are similar in cultivation, and with the blessing of this thing, the little ghost immediately bows down to the big ghost!

It seems that this item may be the treasure of a high-level soul clan cultivator!

"Wait a minute!" Dao Wuya suddenly took the long hook, but the long hook turned into a black fragment in Dao Wuya's hand.

"Uh......" let the little ghost hold it, only to see that the black fragment turned into a black iron ring again!

Could it be that this treasure will choose people to change?

Thinking like this, Dao Wuya took it from the little ghost again and threw it outside the Dao Sutra, only to see that the black fragment turned into a huge black pillar again, and because it lost the control of hundreds of seals, the black giant pillar made the entire heart of the earth hurt like stirring the wind and clouds.

Dao Wuyi was shocked and recalled the black giant pillar!

However, when the black giant pillar returned to Dao Wuya's hands, it turned into a black fragment again!

"Strange!" Dao Wuya handed over the black fragment to the big ghost, puzzled.

It can only be proved that the Dao Sutra Soul Void is a treasure far above this black giant pillar, because it can easily control this thing, and the Dao is endless.

Dao Wuya controlled the Dao Bead to rise slowly, and found that all the fire spirit beasts in this place were actually dead!

"Could it be that the spirit beasts led by the commander of the thousand men have also died?"

At a depth of 10,000 miles, there is no trace of spirit beasts at all!

At this time, the Burning Sky Flame was still in the second layer of the Dao Sutra, and the Dao had no time to take care of it.

Dao Wuyan manipulated the Dao Sutra to slowly swim upstream, and sure enough, there was no trace of spirit beasts!

"What about Bai Yan?" Dao Wuyan thought secretly, "This fire spirit beast seems to have a noble status in the Earth Center Flame Country!"

Finally swimming to the position of Qianzhang, Dao Wuya no longer needs to hide, and controls the Yin and Yang Xuanbing Ice and Fire to slowly swim upstream.

Dao Wuya felt that some indescribable changes had taken place here, but he couldn't put it into words.

"Fellow Daoist?" When Dao Wuwu swam to two hundred zhang, he suddenly heard a summons.

It turned out to be Bai Yan!

But Bai Yan seemed to be scarred and his breath was disordered.

"What's wrong with you? Dao Wuya asked, swimming to Bai Yan's side.
