As soon as the wee hours of the morning arrived, a dense and shrill whistling sounded again in the sky of the frozen highlands.

The dragons gathered in large groups, like sharp swords, in batches to attack the demon legions below.

They are like cunning wolves, tearing off chunks of flesh from the prey of the demon legion as a feast.

The Legions of Hell, which lack an air force, have no way to deal with these allosaurs, and only a very small number of "banshees" can fly in their troops, but these demons who are skilled in using magic have no effective means of suppressing the swift and fierce allosaurs.

Banshees can unleash a variety of different curses to weaken their enemies, and when their opponents are weakened, they use ranged magic to kill their opponents.

But this method is completely useless for the allosaurus.

First of all, the quantitative gap between the two sides is too large.

The group of xenosaurs brought to the battlefield by Zagara was a full half a million of them, and if they were to attack together, they would be enough to shroud the entire frozen highlands region and even a small half of the bloody hills in a dark shadow.

Second, the allosaurs' light exoskeleton armor and special chemical structure in their bodies have been able to adapt to and resist the vast majority of magical damage in this world, at least with these banshee projections alone, it is difficult to hang the curse on them.

And once the speed of the allosaurus cannot be weakened, then for the banshee, the allosaurus becomes the most terrible nightmare.

They are larger, more destructive, and unusually ferocious, and the ability to shoot bladeworms in all directions to inflict a large amount of collateral damage makes it very difficult for banshees as magical units to deal with.

After striking once and being wiped out by the dragons in seconds, the Demon Overseers in command of the Banshees hid their remaining forces and turned a blind eye to the dragons' air raids.

Ever since the four Legendary Cultivators ordered the Hellcultists to immediately begin the sacrificial ritual, the dragons in the sky have been frantically harassing the demon legions.

In addition to the Xenosaurus, there are also invisible killers who have infiltrated the core of the Hell Legion, and these unseen creatures have caused huge casualties to the Hell cultists.

It wasn't until the legendary Evil Pact Druidwin began to transform into bats to patrol the sacrificial site that the assassination of the Hellcultists slowly stopped.

Soon, however, the cages where the sacrifices had been captured went wrong again, and many of the sacrifices were released, and as long as they were allowed to flee to the open space outside, they would never be caught again.

In desperation, Marven had no choice but to personally guard the sacrificial prison, which allowed the Demon Land Transformation Ritual to continue.

This series of various attacks and rescue operations has exhausted the four Legendary Cultivators, and what makes their scalps tingle even more is that the sky is about to dawn, which means that the general assault of the swarm and the human legion on the frozen highlands is about to begin.

The Maquin brothers, with the largest number of servants in the Demon Legion and the Hammer of Death, guarded the core area of the Demon Army's camp, and a large group of ice monsters loomed in the raging snow around the camp.

These are elemental monsters formed by demonic souls gathering the ubiquitous ice and snow of the Arret Mountains, their bodies are made entirely of frost, and they are inherently immune to frost spells and energy.

Moreover, these Ice Demons also cast Polar Storms, summoning harsh blizzards from the far north to help them fight.

The ice curtain that now surrounds the main camp of the demon army was summoned by them.

In addition to the Ice Monsters, the elite guards at the innermost level of the ritual point and led by the elder brother of the two brothers are one of the most powerful demon breeds under Baal's command, the most powerful demon besides Baal's Praetorian Guard, the Blood King.

These demons resemble blood-red minotaurs, clad in strong armor and armed with twin axes, and are extremely adept at hand-to-hand combat, using most of the Barbarian's combat skills.

The Blood Kings are nearly three meters tall, powerful, and extremely manic, and once they go berserk, they won't even tell whether the opponent in front of them is an enemy or their own.

These demons are few in number but very powerful, and even if they are just projections, they all have a level of 70 or higher.

In the old days of Harogas, these monsters could only be seen by professionals very close to the Temple of the World Stone, and their sheer power was a nightmare for every melee warrior in the professional squad.

In addition to the Blood King, the Hell Army Headquarters is surrounded by a large number of demonic goblins and siege beasts.

The two can form a synergy - the siege beast is a behemoth that reaches seven or eight meters in height, these monsters are stupid and rough, and they only know how to charge forward with one force on the battlefield.

Baal had its Hellsmith create a piece of equipment with mounted armor for these beasts. They are often manipulated by demonic goblins, otherwise they are almost impossible to control.

However, it is said that the demon goblins did not actually control them, but only used their height advantage to attack.

But even if that's all, this combination is quite cumbersome and difficult to deal with.

The Demon Elf uses teleportation skills, and it can escape from the back of a siege beast at any time.

The rough skin and thick flesh of the siege beast are very durable, which largely supplements the weakness of the demon goblin's body.

The headquarters of the Hellish Army was established in the middle of a large barbarian village they occupied, and the Demon Overseers used the remaining buildings and stone walls of the village to construct a line of defense, including many towers and reinforced walls for the use of the Demon Elves.

They hope that this line of defense will do at least a little bit to keep out the human forces and swarms that are trying to attack from the front.

However, they were wrong, and so were the four Legendary Cultivators.

Ever since he learned that Anya had been captured, Xue Hua had no intention of continuing to play this hellish game with them.

Not long after the wee hours of the morning, three waves of earth suddenly erupted in the Demon Camp on the frozen heights.

The three-headed Void Digger burrowed directly from beneath the ritual altar of the Hellcultists, instantly turning hours of hard work of the Hellcultists into water.

Then, an army of dragons and prowlers and corruptors descended from the sky, seizing air supremacy of the battlefield in an instant and wiping out the demons who tried to prevent the Void Diggers from expanding the fungus carpet.

The four Legendary Cultivators burst out of the band to put up a stubborn resistance, but Qualkek, Clough, McCass, and Kashya quickly appeared and stopped them one by one, while Kidd led a legion of human professionals and barbarian troops to be the first to burst out of the mouth of the three-headed Void Borger.

At the same time, the three-headed Void Diggers quickly deployed the fungus blanket, followed by more than twenty pit worms.

Countless swarms of insects poured out of the mouth of the tunnel worms, completely submerging the elite Blood King troops in an instant like rolling waves.

The battle on the frozen heights has directly entered the white-hot phase from the beginning.
