"Purple Flame Earth Heart Fire, come out!"

Lin Feng let out a low snort.

He directly sacrificed the heavenly fire he had refined.

After the Purple Flame Earth Heart Fire flew out, it hovered in mid-air.

Lin Feng asked, "What should I do now?"

"Divine thoughts, divine thoughts and purple flame earth heart fire fused together, attack the black flame burning divine fire with me."

The demon monarch said a little anxiously.

Obviously, the situation of the Demon Monarch is not good now.

His power is waning.

That's because he was consumed by the Black Flame Burning Divine Fire.

Black Flame Burning Divine Fire said at this time, "Boy, don't listen to his nonsense, do you know who this guy is?" In the primeval era, he was one of the giants of the immortal realm who mastered the prison, this person killed people without blinking, his primordial spirit was shattered, and only the remnant soul remained, so he didn't do anything to you, I know his character too well, and when his primordial spirit gradually recovers, then you will die without a place to die, and I, the Black Flame Burning Divine Fire, will not deal with you, it is too dangerous for the heavenly fire to devour each other, it is likely to die, I am not willing to take risks, so boy, leaving here now is the wisest choice."

Now the relationship between Lin Feng and the Demon Monarch has eased a lot.

That's why he trusts the Demon King even more.

Instead of the Black Flame Burning Divine Fire.

When the Dark Lord reached an agreement with the Black Flame Burning Divine Fire, they were both calculated to death by the Black Flame Burning Divine Fire.

How could Lin Feng believe him?

"Shut up".

Lin Feng sneered, and his divine thoughts merged into the Purple Flame Earth Heart Fire.

Then he flew over.

Lin Feng manipulated the Purple Flame Earth Heart Fire to wrap the Black Flame Burning Divine Flame.

The Black Flame Flame emitted terrifying fluctuations.

At this time, Lin Feng felt that the Purple Flame Earth Heart Fire was trembling.

This is the suppression of heavenly fire.

The Black Flame Divine Fire belongs to the dark attribute of the Heavenly Fire.

There are five types of dark attribute skyfire.

They are the Dark Emperor Fire, the Dark Devouring Divine Fire, the Dark Devouring Sky Fire, the Dark World-Destroying Fire, and the Dark Burning Divine Fire.

The Dark Burning Divine Fire is the fifth-ranked Heavenly Fire among the five Dark Attribute Heavenly Fires.

But even so.

Among the seventy-two kinds of heavenly fires, the Dark Burning Divine Fire could also be ranked to sixty-five.

And the Purple Flame Earth Heart Fire is the sixty-seventh place.

The Purple Flame Earth's Heart Fire is in front of the Black Flame Burning Divine Fire.

It belongs to the low-level heavenly fire.

Between the sky and fire, even if there is only a small difference.

But it can also create a huge racial oppression.

So.

The repression is great.

Now the Purple Flame Earth Heart Fire has been oppressed by the Heavenly Fire race.

Lin Feng felt that the Purple Flame Earth Heart Fire seemed to want to escape.

"Burning Origin!"

The Demon Monarch also showed that something was wrong, and he began to burn his origin power.

Burning the Origin.

It's usually the last minute, and there's really no way out.

will choose to do so.

Because this hurt too much.

Now.

The Purple Flame Earth's Heart Fire was suppressed by the Heavenly Fire of the Black Flame Burning Divine Fire and wanted to escape.

Therefore, the demon monarch had to resort to the last resort.

The Demon Monarch obviously wanted to use the power of the Purple Flame Earth Heart Fire and the Burning Soul Origin to fight the fire spirit of the Black Flame Burning Divine Fire to live and die.

After burning its own origin, a large amount of pure energy is generated.

All of this energy was infused into the Purple Flame Earth's Core Fire.

With the infusion of this majestic power, the Purple Flame Earth Heart Fire also became stronger.

Bang......

The Purple Flame Earth's Heart Fire began to rush towards the Black Flame Burning Divine Fire.

The two heavenly fires collided violently.

"Damn"!

The fire spirit of the Black Flame Burning Divine Fire couldn't help but shout angrily.

Originally, he was going to devour the Demon King.

Now it has fallen short.

The fire spirit of the Black Flame Burning Divine Fire was naturally extremely angry, he looked at Lin Feng coldly, and threatened, "Boy, hurry up and remove the Heavenly Fire, otherwise, I will let you live rather than die later."

Lin Feng sneered, "It's not certain who will kill the deer, maybe I will refine you later."

"Then we'll see."

The Black Flame Burning God ignited the Thunder Fury.

He also began to burn the origin power to urge the Heavenly Fire Origin of the Black Flame Burning Divine Fire.

Bang bang bang......

The two sides kept colliding.

It's a life-and-death battle.

Either you die or I die.

So, there is no way to back down.

The Demon Monarch is burning the power of his soul origin like a life.

And the same is true of the Black Flame Burning Divine Fire.

There was a tug-of-war between the two sides.

But in this ongoing tug-of-war.

Lin Feng could feel it.

The Demon Lord is getting weaker and weaker.

Originally, it didn't take long for the demon monarch to recover.

Such a big consumption.

Naturally, it will gradually wear out.

This made Lin Feng's face slightly ugly.

If the demon lord is defeated.

Then he is also a dead end.

"Looks like you're running out of it...".

The fire spirit of the Black Flame Burning Divine Fire made an eerie sound.

The demon monarch did not speak, his expression was solemn.

It is constantly burning its own origins.

But there will be a time when the source is almost consumed.

Seeing this battle, Lin Feng also knew that this battle had reached the most critical moment.

He must help the Demon Lord defeat the fire spirit of the Black Flame Burning Divine Fire.

Otherwise.

When the time comes, they will all die.

Lin Feng locked his gaze on the Xuanying Demon Book.

Like the Demon Beads, the Book of the Mysterious Demon Book is extremely strange and extremely powerful.

Lin Feng tried to summon the Xuanyin Demon Book.

But what made Lin Feng quite speechless was.

The Book of Demons was unmoved.

"A drop of immortal blood, how about you shoot once?".

Lin Feng gritted his teeth.

Swish.

The Book of Demons flew out immediately.

The corners of Lin Feng's mouth couldn't help twitching.

This book of the Shadow Demon is really weird.

However, the Book of Demons did not go to attack the fire spirit of the Black Flame Burning Divine Fire.

It's waiting.

Lin Feng couldn't help but force out a drop of immortal blood.

It dripped on the Book of Demons.

As long as you can kill the fire spirit of the Black Flame Burning Divine Fire.

So.

You can get the Heavenly Fire Origin of the Black Flame Burning Divine Fire.

This drop of immortal blood.

It was not in vain.

Devoured a drop of immortal blood.

The Demon Book of the Xuan Netherworld Demon Light Heavy Heaven also rushed over.

"It's ......".

When the fire spirit of the Black Flame Burning Divine Fire saw the Xuanying Demon Book that rushed over, he was taken aback.

"Haha, look at the reversal".

Seeing the Xuanming Demon Book make a move, the Demon Monarch laughed loudly and joined forces with the Xuanying Demon Book.

A more intense battle erupted.

An hour later.

"Hundreds of millions of years ago, I deliberately killed the Dark Lord, I finally survived until now, I saw the hope of getting out of trouble, but now I am going to die here, I am not reconciled."

The fire spirit of the Black Flame Burning Divine Fire let out an unwilling roar.

But the next moment.

His primordial god was shattered by the Demon Monarch and the Xuanying Demon Book.

Then, the Demon Lord and the Xuan Nether Demon Book quickly devoured the fragments of the primordial god of the Black Flame Burning Divine Fire.

After devouring it, the Demon Monarch quickly returned to the magic bead.

The Xuanying Demon Book flew back to Lin Feng's dantian and hid it.

The origin of the Heavenly Fire was suspended in mid-air.

To refine, or not to refine?

If refined, the collision of the two heavenly fires may kill without a place to die.

If you don't refine it, you will miss this opportunity.

Lin Feng only hesitated for a moment, and then directly devoured the Black Flame Burning Divine Fire.

Rumble......

The Heavenly Fire Origin of the Black Flame Burning Divine Fire and Lin Feng's Purple Flame Earth Heart Fire collided wildly.

Wow.

Lin Feng's body was swept out, and a mouthful of blood spurted out of the air.

Two Heavenly Fire Origins.

Sure enough, they don't blend with each other.

Rumble......

An even more terrifying collision followed.

Click, click!

Lin Feng's flesh began to crack like porcelain.

"Damn, are you going to die?".

Lin Feng couldn't help but scold.

He was not willing to die like this.

Lin Feng manipulated the nine drops of immortal god blood in his body.

Powerful immortal power emanated from the nine drops of immortal blood.

poured into Lin Feng's limbs and bones.

Lin Feng's body was quickly repaired.

Under the continuous impact of the two heavenly fires, Lin Feng's physical body was constantly destroyed, and it was constantly restored under the repair of the immortal god's blood.

If it weren't for the blood of the immortal god, I am afraid that I would have died countless times.

After three hours of crazy collisions.

Finally.

The two heavenly fires finally immersed themselves.

"Refining ......".

Powerful mana poured into the Black Flame Flame.

Followed by.

The Black Flame Burning Divine Fire imprinted Lin Feng's breath.

A terrifying force.

Suddenly exploded.

"Boom...".

Powerful fluctuations poured out from Lin Feng's body.

The mana in Lin Feng's body rose wildly.

His realm is rising step by step.

Yin and Yang Realm Double Heaven!

Yin and Yang Realm Triple Heaven!

Yin and Yang Realm Four Heavens!

Lin Feng's realm was directly raised to the Yin and Yang realm, and the peak of the Four Heavens only stopped.
