"Bang!"

With a loud bang, a dark and crystalline heart with a demonic aura like obsidian broke through.

"Boom!"

"Boom!"

"Boom!"

............

The black crystal heart of the ancient demon god was beating violently, full of rhythm, full of majestic breath of life, and the vast power swept in all directions.

"Catch it!"

Emperor Xuanyuan was just about to reach out and grab the black heart, when it "swooped" into the remains of the "Xuanyuan Demon".

"Oh no! The heart of the Ancient Demon God must be fused with the spirit of the Ancient Demon God!"

Emperor Xuanyuan said secretly, not good.

Originally, the "Xuanyuan Ghost Demon" was shattered by his sword and died, and the Nine Ghost Spirits would also perish.

However, fusing the heart of the ancient demon god, the Nine Demon Old Demons will be resurrected again, and their strength will skyrocket!

After all, this ancient demon god's heart contained extremely surging power.

After the heart of the ancient demon god was integrated into the body of "Xuanyuan Demon", his body immediately began to undergo a crazy transformation.

The bones of "Xuanyuan Youxie" made a crackling sound, and his figure instantly grew from one meter eight to more than three meters tall, more than doubling his height.

The muscles of his body bulged and twisted together like dragons, and patches of hideous scales grew on his skin.

A stout, scaly tail grew from the back of his buttocks, and a pair of curved horns grew out of his head.

The whole body is full of demonic energy, full of cold and terrifying atmosphere.

In the blink of an eye, "Xuanyuan Evil Spirit" transformed into a demon of the Nine Hells.

Moreover, his power is still skyrocketing!

"Nine Shadows Old Demon, you must stop him!"

Emperor Xuanyuan's eyes were cold, and without hesitation, he stabbed a sword into the heart of the Nine Shadows Old Demon.

At this time, whether it was the body or the soul, the "Xuanyuan Demons" had been completely replaced and became the real Nine Shadows Ancient Demon.

"Boom!"

The Nine Shadows Ancient Demon stretched out a hideous claw to resist the assassination of the Qianshui Sword.

The Qianshui Sword stabbed into the claws, making a sonorous sound of metal colliding, splashing a trace of sparks.

The sword that was as sharp as clay could not pierce the scale armor on the surface of the Nine Shadows Ancient Demon's body at all, let alone hurt him.

Then, with a slight wave of the Nine Shadows Ancient Demon Claw, Xuanyuan Emperor Yao's whole person flew out upside down like a cannonball, slamming into the iron wall of the main hall, opening his mouth and spewing out a mouthful of blood.

Fast!

It's so fast!

It was so fast that even Emperor Xuanyuan couldn't react, so he was caught and flew away.

Moreover, his strength has skyrocketed several times.

If it weren't for Emperor Xuanyuan Yao's cultivation of the Ten Thousand Tribulations Immortal Body, this body would have burst open under one claw.

After fusing the heart of the ancient demon god, the power of the Nine Demon Old Demons far exceeded the innate realm, and it was still rising wildly.

"Hahaha...... It's been 10,000 years, and the heart of this demon has finally broken out!"

"Hahaha...... Who else in this world can stop this demon?"

"This demon wants to reign over the world and wash the Quartet with blood!"

"Those who follow me live, and those who oppose me die!"

"Hahaha......"

The Nine Shadows Old Demon, whose strength had skyrocketed, let out a maniacal laugh.

Even the entire hall trembled and shook in his laughter, as if it was about to collapse at any moment.

"Hahaha......"

"My Nine Shadows Great Demon God is back!"

"The world will tremble because of me!"

"All the human races will be prostrate at the feet of my Nine Shadows Great Demon God!"

"Hahaha......"

The Nine Shadows Old Demon laughed wildly, as if he wanted to vent all the repression caused by his imprisonment for more than 10,000 years.

"The abominable Human Emperor, you have imprisoned this demon for 10,000 years!"

"For the past 10,000 years, this demon has been tortured day and night!"

"This demon is immortal and immortal!"

"Ben Mo said that one day he will come back for revenge!"

"It's a pity, the old guy of the Human Emperor, is actually dead, and he can't let this demon take revenge with his own hands!"

A ghostly light shot out of the eyes of the Nine Shadows Old Demon.

With a wave of his claws in the air, Xuanyuan Emperor Yao's entire body flew out upside down and smashed into the ground, staining the hall red with blood.

"Mole ant, you're too weak!"

The eyes of the Nine Shadows Old Demon were full of banter.

Fused with the heart of the ancient demon god, making his power skyrocket.

Now, although his strength is less than one-ten-thousandth of that of his peak, it is not something that an innate cultivator can face at all.

The Nine Shadows Old Demon was not in a hurry to kill Emperor Xuanyuan, but wanted to play with him.

At this moment, two figures rushed into the hall, both of whom were bigwigs in the military department.

"Nine Old Demons, he ...... He's really out of trouble!"

When the two bigwigs saw the Nine Shadows Ancient Demon, they both showed a look of horror.

This is the ancient demon god of the demon world, a terrifying old demon who was sealed and suppressed by the human emperor himself 10,000 years ago!

Now that the human emperor is gone, this old devil will definitely become a huge catastrophe when he gets out of trouble!

"This old devil has just broken the seal, and his strength has not fully recovered, now is the best time to kill him!"

"Yes, we can't let this old demon escape and harm the world!"

After the shock, the two military bosses quickly came back to their senses.

They are the high-level leaders of the Xuanyuan family's military department, and each of them is an existence that has experienced a hundred battles.

Even demons, they have slaughtered a lot.

They soon realized that now was the best time to deal with the Nine Shadows Old Demon.

If you wait for the Nine Shadows Old Demon to return to its peak, I am afraid that in the entire Xuanyuan City, no one can help him.

"Kill!"

The two military bosses used their strongest martial arts at the same time and slaughtered the Nine Ancient Demons.

"Mole ants, don't do your best!"

The Nine Shadows Ancient Demon showed disdain, and he didn't look at the two military bosses squarely.

His two arms stretched out, and when he heard the storm, he turned into terrifying giant claws dozens of feet long in the blink of an eye.

The terrifying giant claw instantly disintegrated all the attacks, and then pinched the two military bosses between their fingers like catching ants.

"Die!"

The Nine Shadows Old Demon coldly spat out a word.

The bodies of the two military bigwigs suddenly exploded into a cloud of blood mist.

"Hahaha...... Is this the power of the Xuanyuan City Military Department?"

"It's too weak!"

"Hahaha......"

The Nine Shadows Old Demon casually destroyed the two military bosses, and set his sights on Emperor Xuanyuan again.

"The human emperor is dead! This demon king is in the world, who can stop me in this world?"

The Nine Old Demons were full of spirit, revealing a domineering spirit that reigned over the world.

When his strength is restored to its peak, the entire world will tremble at the feet of his Nine Shadows Ancient Demon God!

Xuanyuan people, he will slaughter them all!

All the human races will be transformed into blood slaves by him.

"Hahaha...... Nine Shadows Old Demon, you're so carried away!"

"You forgot, what sealed you here?"

At this time, Emperor Xuanyuan had already stood up again.

And his blood, through the remnants of the formation runes, soaked into a crystal pillar.

That pillar was the center of the sealing formation, and at this time, it absorbed the blood of Emperor Xuanyuan and bloomed with brilliant light.

"Whoosh!"

A golden light flashed, and the sealing pillar shrank sharply, turning into a crystal clear magic pen, blooming with divine brilliance!

"The Emperor's Pen!"

The Nine Shadows Ancient Demon immediately showed a look of horror!
