All the cities in the Demon Kingdom of the Underworld, the central place is the most important core place.

The six-story Demon Dragon Altar is all in the core of this central place, which is connected to the Demon Dragon Vein and National Fortune of the entire Demon Kingdom of the Dark Qin.

It is the last retreat of the demon cultivators and ghosts loyal to the Demon Kingdom of Hades and Qin in the city!

They can use the 'six-layer altar' to use the Demon Dragon Vein of the Demon Kingdom of the Stygian Qin as a channel to teleport away.

Therefore, in every city, the demon cultivators and ghost creatures of the Stygian Qin Demon Country, unless there are special circumstances, will not destroy this last retreat, but must vigorously protect it.

And for the army of ghosts under the dark night, the central area of the city is a key protection area.

In particular, the six-story altar located in the central area, which suppressed the demon dragon dragon vein and national fortune of the Demon Kingdom of Stygian Qin, was the thing that Yu Ye valued and needed the most.

Naturally, he can't let his army of ghosts give him destructive power.

Therefore, under the protection of both the attacker and the defender, intentionally or unintentionally, although most of the city on the top of the mountain has been reduced to ruins in the chaotic battle, the central area of the city is very well preserved.

Perhaps, in the final stage of the battle, the demon cultivators and ghosts of the Demon Kingdom of the Stygian Qin already knew that they could not escape, and thought about destroying the six-story altar in the central area of the city.

Therefore, in the well-preserved central area of the city, you can occasionally see a few traces of fighting and colliding.

However, the demon cultivators and ghost creatures of the Stygian Qin Demon Kingdom had obviously failed, and those traces were only on the periphery of the central area, and they did not cause any damage to the sixth-layer altar in the center at all.

Obviously, it has long fallen into the hands of the ghosts of the dark night, and it is well protected.

Now, Bai Ye followed the jade skeleton into the city, straight into this central area, and arrived in front of the six-story altar.

The altar was carved with statues of six demon dragons, almost exactly the same as the altar where Hakuya had seen the demon dragon devouring in the dark night.

In front of the six-story altar where the jade skeleton walked, a pair of white jade bone claws held the imitation 'battle map' and placed it on the altar.

"Groan!"

A dragon roar sounded from the imitation of the 'battle map', and a dark light diffused from the 'battle map', spreading, and shrouded towards the entire six-story altar.

"Groaning ......"

On the six-story altar, the carved six demon dragons suddenly came to life and let out a long dragon roar.

The heads of the six hideous demon dragons rose in unison, spewing out magic light, fighting against the dim light illuminated by the 'battle map', and they couldn't compete for a while!

At this time, the jade skeleton stretched out its hand to the sky and made a move, and the 'magic decree' unfolding in the sky suddenly flew down and landed directly on the altar.

The big seal of the 'Demon Dragon Dragon Seal' under the cover of the 'Demon Decree' instantly burst into a magical light, directly suppressing the six demon dragons that were fighting.

The imitation of the 'battle map' took the opportunity to attack, and the dim light under the light instantly captured the six demon dragons that were suppressed, and went directly to the 'battle map'.

"Groan!", "Groan!", "Groan......"

The six demon dragons struggled desperately, but with the suppression of the big seal under the cover of the 'Demon Dragon Dragon Seal' above the 'Demon Decree', it was useless at all, and in the blink of an eye, it was included in the imitation of the 'battle map' by the dark light!

"Click!" "Click!" "Click......"

The six demon dragons were captured by the 'Battle Map', and the altar suddenly lost all its spiritual light, and the sound cracked, and cracks appeared everywhere on the altar.

In particular, the six demon dragon elephants carved on it directly collapsed and fell off.

With the complete destruction of the six-story altar, the city above the high mountain defense line also marked the complete fall.

Standing on this high mountain, Bai Ye raised his eyes and looked ahead, and he could already see the plateau not far ahead, like a dragon entrenched.

At this time, the Jade Skull contacted the night that was far away from the other side to preside over the battle, and presented the 'Six Demon Dragons' that had just been photographed, reported the results of this attack, and listened to the next order.

And soon, the order came from the night!

The attacks on the six fronts have all successfully captured the high mountains, and now they have each opened the entrance to the portal of the Stygian Qin Demon Country.

The next step is to directly enter the plateau, rush all the way, and kill the Dark Qin Demon Capital in the center of the plateau.

After receiving the order of the dark night, the jade skeleton immediately reorganized the army, and the army of skeletons, zombies, ghosts, and blood demons and cannon fodder was completely replenished.

In the end, the five armies set off together and attacked directly towards the plateau behind the high mountains.

The elite army commanded by the Jade Skull followed closely, and the city defense line on the high mountain did not leave anyone to defend it!

This time to attack the Stygian Demon Country, the Dark Night fought the idea of a battle, and it was to kill the Stygian Demon Capital in one go, devour the demon dragon veins of the Stygian Demon Country, and completely destroy the Stygian Demon Kingdom.

Therefore, the subordinates of the dark night, laying down every line of defense, did not leave the intention of leaving manpower to guard, but gathered all the forces and directly killed the Demon Capital of the Dark Qin in the strongest state.

After the high mountain, on the way up to the plateau, another city defense line blocked the way.

However, it seems that because of the high mountain defense line in front, the direction of this climb to the plateau is not as advanced and tight as the mountain defense line!

Under the repeated strong attacks of the Fifth Route Army, the defense line on the plateau was broken in many places.

And, again, at the most critical moment.

In the city in the direction of this plateau, there is also a group of internal responses, which directly launch a rebellion, killing and destroying from the inside.

In the end, the plateau defense line was broken faster than the mountain defense line.

The five-way army under the dark night quickly ascended the plateau and completely penetrated into the territorial defense line of the Stygian Qin Demon Country.

The jade skeleton familiarly took the demon dragon veins of the Dark Qin Demon Kingdom and the six demon dragons transformed by the national fortune in the six-story altar in the city, and collected them into the 'battle map' and gave them to the dark night.

A new batch of 'set things right' joined the army, so the army and strength under the Jade Skull were not weakened by the two wars, but strengthened.

Still did not stay, did not leave troops to guard, the jade skeleton used all its strength to kill towards the depths of the plateau.

The route of the attack was already planned by the dark night, and it was not a straight line, pointing directly at the Demon Capital of the Dark Qin.

Instead, there were several turns and detours, but they all pointed to several key cities and defense lines in the Demon Country, all of which were key nodes of the 'Demon Dragon Pantian Great Array'.

The dark night has the 'Demon Dragon Dragon Seal', which has the most comprehensive inheritance of the 'Demon Dragon Pantian Great Array', and naturally knows how to break the formation the most quickly, conveniently, and correctly.

The Jade Skull commanded the army, and attacked all the way according to the route planned by the dark night, but every defense line had internal help, and the momentum was like a bamboo, the stronger it became, like a snowball, and the Demon Kingdom of Hades and Qin had no power to resist at all!

Bai Ye followed behind, and it was extremely easy along the way, and there were not a few opportunities to make a move at all.
