Three days later, the three grand demon kings led their subordinates and entered the Immortal Graveyard. They worked together to resolve the dangers of the Immortal Graveyard.

The three of them were absolute hegemons of the Demon Area, and they also had powerful cards up their sleeves. In addition, with the help of many great demons, they broke through layers upon layers of restrictions like a hot knife through butter.

Breaking the restriction in the sky, the three demon kings didn't slow down at all and continued to control their treasures to break the restriction in the Undying World, slowly moving towards the core of the restriction.

"Shoo! Shoo! Shoo!"

One after another, ear-piercing sounds of something tearing through the air rang out.

The three Demon Kings raised their speed to the peak and quickly rushed towards the black castle. They wanted to break through the restrictions that shrouded the black castle and enter it to steal the treasures.

When they broke through the first layer of the barrier with unstoppable force, they suddenly stopped, and their expressions underwent a great change.

They discovered that there were twelve men in black armor with spears in their hands standing beneath the huge city gate. They emanated a thick aura of death.

Just from the first glance at them, the three great demon kings could already sense how terrifying they were. The aura of death emanating from their mountain gave them an even more suffocating feeling.

"What a terrifying puppet, just what kind of great opportunity did this great character leave behind!"

Looking at the twelve black armored men in the distance, the three Monster Kings spoke with a grave expression.

However, they couldn't part with the treasures of the black castle. Even though they knew that there were many dangers, they still didn't retreat.

"You, go and test their strength!"

The Qilin King waved his hand and ordered one of his subordinates to test the strength of twenty black-armored puppets.

"Yes, yes!"

The Qilin King's throat rolled. Although he knew the dangers of going to test it out, he was more clear on the Qilin King's methods. He had no choice but to brace himself and slowly slowly approach.

"Buzz buzz buzz!"

When this great demon neared the twelve black-armored puppets, they simultaneously opened their eyes. Streams of cold light shot towards this great demon, causing him to feel as though his body was being pierced by a cold light.

Just as the Diremonster sensed the danger and instinctively wanted to dodge, the aura of death emanating from the twelve black-armored golems suddenly began to condense. Like a rolling black stream, it pierced through his body, smashing him apart and blasting apart the hard monster cores.

"How terrifying. These twelve golems most likely reached the pinnacle of the Six Star Fiend level!"

Upon seeing the strength of the twelve black-armored puppets, the expressions of the three great demon kings darkened. They didn't dare to act rashly.

"Alright, stop hesitating. Do you think it's possible to obtain the great opportunity inside without paying a price?" The Peacock King took a deep breath as he spoke.

"Good, there's an Ancestral Statue attack!"

Ancestor was like the last technique bestowed upon the three great demon kings by the demons of the Void God Realm.

Once the energy contained within the Ancestral Statue was exhausted, they would lose their greatest reliance. It was very likely that the two Demon Kings would make use of this opportunity to annex their forces.

But at this moment, upon seeing the power of the twelve black-armored golems, they knew that they had no other choice. They had no choice but to summon their three great Ancestors, then borrow their power to annihilate the twelve black-armored golems.

"Puff puff puff!"

The three demon kings each spat out a large amount of blood essence, which merged into the three great ancestor statues they had summoned and activated them. A terrifying aura of Ancestral Aura emanated from the three ancestor statues, instantly suppressing the death aura emitted by the twelve black-armored puppets, shattering the seal.

"Ancestral statue, I didn't expect the three Monster Kings to have such a trump card!"

As he looked at the statue that was floating in midair and releasing its powerful aura, Ye Chenfeng, who was mixed in with the crowd, revealed a surprised expression.

"Ancestral Statues, annihilate them!"

The three demon kings shouted in unison. The ancestral statues that had been activated continuously expanded as they attacked the black-armored Puppet with their powerful Ancestral Energy.

"Crack!"

The three great Ancestors shined with boundless light. With a single step, they split the hard space apart. With the power of their ancestors, they swept through the entire space, annihilating twelve black-armored puppets.

"Buzz buzz buzz!"

Sensing the danger of the three statues, the twelve black-armored golems immediately joined forces to attack. Streaks of sharp spear light pierced through the void, dancing about like black dragons as they battled against the three statues outside the black castle.

The twelve black armored puppets were created by the Undying Demon Ancestor, and not only were their offensive capabilities astonishing, their defensive capabilities were also extremely terrifying. However, the three great ancestor statues were the final trump cards of the three great demon kings, and their strength had surpassed the limits of the Divine level.

However, as time passed, the strength of the three great Ancestors slowly began to show. Their terrifying attacks completely suppressed the twelve black-armored golems, and caused their incomparably tough black armor to crack and crack.

Seeing the twelve black-armored golems being destroyed by the three great Ancestor statues, suddenly, streaks of black light shot out from the depths of the black castle and poured into the twelve great black-armored golems, quickly repairing their damaged bodies and allowing them to continue battling against the three great Ancestor statues.

"What!"

The expressions of the three great demon beasts all became gloomy.

After battling for a few hours, the consumption of the three great Ancestors was very obvious. If they could not shatter the black-armored puppet, the consumption of the three great Ancestors would be even greater and their foundation would be greatly weakened.

"What are you all standing there in a daze for? Hurry up and attack! Annihilate these twelve black-armored golems!"

The gloomy faces of the three grand demon kings ordered loudly, ordering their subordinates to attack the black-armored Puppet together.

Under the simultaneous attack of more than a hundred Diremonsters, the injuries of the twelve black-armored golems became even more severe, and the number of cracks on their armor grew even greater.

Just as they were about to be destroyed by the combined attacks of the other monsters, from within the black castle, streaks of black light shot out, piercing into the bodies of the twelve shattered black-armored golems, repairing their wounds and continuing to attack.

"Fuck, let's cut off space together!"

Watching the black-armored puppet's body being repaired by the black castle time and time again, the three Demon Kings were furious. They summoned large numbers of formation flags without sparing any effort, fusing them together to form a powerful defensive formation that forcefully severed the connection between the black castle and the twelve black-armored puppets.

"Boom boom boom!"

The sounds of fierce fighting became louder and louder.

When the twelve black-armored golems were smashed apart for the third time by the combined attacks of the three great ancestor statues and the other monsters, the black light that the black castle had released was blocked by the combined power of the three monster kings.

"Destroy!"

Seizing this opportunity, the three great demon kings continued to pour blood essence into the three great Ancestors, unleashing the strongest power of the three great Ancestors and destroying the twelve black-armored puppets.
