He must help the demon king defeat the fire spirit of the Black Flame Burning God Fire.

if not.

They will all die by then.

Lin Feng fixed his gaze on the Xuanming Magic Book.

The Xuanming Magic Book, like the Magic Pearl, is extremely strange and extremely powerful.

Lin Feng tried to summon the Xuanming Magic Book.

But what left Lin Feng quite speechless was.

Xuan Ming Magic Book was not moved at all.

"How about one drop of immortal blood, and you take action once?".

Lin Feng gritted his teeth.

Swish.

The Xuanming Magic Book flew out immediately.

Lin Feng's mouth couldn't help but twitch.

This Xuanming Magic Book is really weird.

But Xuanming Magic Book did not attack the fire spirit of Black Flame Burning God Fire.

It's waiting.

Lin Feng reluctantly forced out a drop of immortal blood.

It dropped on the Xuanming Magic Book.

As long as it can kill the fire spirit of the Black Flame Burning God Fire.

So.

You can get the source of the sky fire of the Black Flame Burning God Fire.

This drop of immortal blood.

It is not paid in vain.

Swallowed a drop of immortal blood.

Xuan Ming's magic book, the Demonic Light, also rushed over quickly.

"This is……".

When the fire spirit of the Black Flame Burning God Fire saw the Xuan Ming Magic Book rushing over, he was shocked.

"Haha, look back again".

Seeing Xuanming Magic Book take action, Yaojun laughed and joined forces with Xuanming Magic Book.

A more intense war broke out.

An hour later.

"I deliberately killed the Dark Lord hundreds of millions of years ago. I have managed to survive until now, and I see hope of getting out of trouble. But now I have to die here. I am not willing to accept it."

The fire spirit of the Black Flame Burning God Fire roared unwillingly.

But the next moment.

His soul was destroyed by the demon king and the Xuanming Magic Book.

Then, the Demon Lord and the Xuanming Magic Book quickly swallowed the fragments of the Black Flame Burning God Fire's soul.

After swallowing it, the demon king quickly returned to the magic bead.

The Xuanming Magic Book quickly flew back to Lin Feng's dantian and hid it.

The origin of the sky fire is suspended in mid-air.

To refine? Or not to refine?

If it is refined, the collision between the two kinds of heavenly fire may result in death without loss of life.

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

Lin Feng only hesitated for a moment and then directly swallowed the Black Flame Burning God Fire.

boom……

The origin of the sky fire of the black flame burning god fire and Lin Feng's purple flame earth core fire collided crazily.

Wow.

Lin Feng's body was thrown away, and a mouthful of blood spurted out in mid-air.

Two sources of heavenly fire.

As expected, they don't blend in with each other.

boom……

An even more terrifying collision followed.

Click click click!

Lin Feng's body began to crack like porcelain.

"Damn it, are you going to die?".

Lin Feng couldn't help but curse.

He was not willing to die like this.

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

Waves of tyrannical immortal power emitted from the nine drops of immortal blood.

Flowing into Lin Feng's limbs and bones.

Lin Feng's physical body was quickly repaired.

Under the constant impact of the two kinds of sky fire, Lin Feng's body was continuously destroyed, and then restored with the repair of the immortal blood.

If it weren't for the blood of the Immortal God, I'm afraid he would have died countless times.

After three consecutive hours of crazy collision.

finally.

The two kinds of heavenly fire finally immersed themselves in each other.

"Refining...".

Powerful mana poured into the Black Flame Burning God Fire.

Immediately afterwards.

The Black Flame Burning God Fire was imprinted on Lin Feng's aura.

A terrifying force.

Suddenly broke out.

"boom…".

Powerful waves surged out of Lin Feng's body.

The magic power in Lin Feng's body increased crazily.

His realm has been rising steadily.

The second heaven of Yin and Yang realm!

The third heaven of Yin and Yang realm!

The fourth heaven of Yin and Yang realm!
Chapter completed!
