Meteorites continued to fall from above, and golden-red flames began to spread across the walls.

In the chaos, the firepower of the fortress suddenly decreased, and the Kuroshio Tide, which had been temporarily slowed down by artillery fire on the plain, began to accelerate again, and the wave at the front was almost close to the city wall.

At this time, the dense spell runes on the city wall began to glow, and a bright holy light flashed from the city wall, and the golden-red flames were swept away by the blooming holy light.

The light rose higher and higher, until it formed a huge energy shield above the crowd, isolating all falling meteorites.

Huge meteorites continued to fall on the light mask, but they could only explode fireworks above everyone.

The situation in the fortress was stabilized again, the Crystal Cannon defense line was once again roaring, and in addition to the soldiers, there were some more priests in white robes on the city walls.

The priest group led by Hubert also rushed to the battlefield immediately after opening the rune defense of the city wall, and the priests ran between the wounded, and under the flash of white light in their hands, the wounded quickly recovered their combat effectiveness.

Amid the roar of war and the roar of monsters, the siege became more and more intense, and gradually came to a climax.

The demon tide at the forefront had already used countless monster corpses to drip through the thunder hell formed by the bombardment of the magic crystal cannon, and pounced on the base of the wall of the Black Mountain Fortress.

The monster's excited roar seemed to be close at hand, and the contractors above couldn't help but turn pale.

Several contractors leaned slightly over the city wall, only to see that there were monsters with entangled limbs below, and they were constantly clinging to each other, forming a pile of tall mountains of meat piled up on the city wall.

Dense thunder flashed on the city walls and spread over the Roshan Mountain, crackling movements resounded endlessly under the city walls, and the rich smell of meat began to spread, and it could be smelled clearly even on the city walls.

"Are these monsters really life?"

A contractor took a few steps back in horror by the horror below, and the monsters seemed to have no pain, no fear, only endless violence and greed.

The smell of flesh had turned into a choking scorch, and billowing black smoke came from under the city walls, which were the smoke emitted from the scorched flesh by the thunder, and the scene at the base of the wall was no longer enough to describe hell.

Countless monsters with hideous faces and sharp teeth rushed to the city wall, stacked into a mountain of meat.

But soon, the whole Roshan turned into char under the boiling thunder, wailing and smoke rising, but even so, the monsters continued to pounce forward, one Roshan fell, and one hundred and ten Roshan rose again, and then unsurprisingly turned into a pile of coke and collapsed.

In this cycle, the coke piled up more and more, gradually forming an upward slope, and the stacks of monsters were piled higher and higher, slowly approaching the middle of the city wall.

On the ship, Thorne stood on the edge of the guardrail, looking down at the fortress below, his face solemn.

From the commanding view from the airship, the entire fortress has been completely wrapped in the black tide, like an isolated island on the sea.

The black tide continued to churn out layers of waves, slammed heavily on the four city walls, and then collapsed and dispersed in the thunder light.

The Kuroshio seems to be doing useless work, but at the same time as the waves are dissipating, the Kuroshio is also gradually rising at a slow speed, and there are more and more monsters passing through the Thunder Pulp Purgatory behind, and the waves of slapping are also higher and higher, and the monsters are preparing to completely flood the entire Black Mountain Fortress in this way.

"General, this monster offensive can be described as crazy, and if it goes on like this, the rune defense of the fortress will not last long."

"Defending both sides at the same time, the load on the energy shield is too heavy."

The voice came from behind, it was the chief engineer Rebecca, she looked at the scene below, her face was worried, most of the defense system in the fortress was handled by her, so she knew where the limit of rune defense was, with such siege intensity, the energy shield would last for a maximum of 6 hours.

The Black Mountain Fortress's defenses are much more than that, but there are many traps and magical defenses that require the use of elves and mages to activate.

But now that elves and humans are enemies of each other, and mages have parted ways with the Empire, the fortress's defenses are vast, and this time it will inevitably look dwarfed by such an unprecedentedly frantic siege.

After listening to Rebecca's words, Thorne's face remained unchanged and he said in a deep voice.

"It's okay, the agency is the organ after all, and it depends on us soldiers who can defend the city in the end."

"By the way, Kairos, they didn't leave the fortress."

Rebecca, who came later, thought back to the glow purple fire that rushed out from the back of the fortress half an hour ago, and should arrive:

"I broke out an hour and a half ago."

"Okay, give Hubert the order, close the wall defense, just hold the top, and I'll take care of the frontal defense."

"Good!" Rebecca agreed, not at all worried about whether the main general Thorne would be able to block the monster in front of her.

"Hahaha......"

After hearing Rebecca's promise, Thorn Lang smiled, turned away from the guardrail, and the cloak behind him agitated, turning up red waves, and the lava armor on his body began to glow, red hair rose, and the whole person was like a volcano about to burst.

"The flyship is ready to drop anchor, and the Purgatory Army is ready to kill all the demon cubs below."

The sound was like a huge thunder, resounding through the airship.

……

On the battlefield, the monster mountain at the base of the wall can already be stacked to the middle of the wall, and the slope below is getting higher and higher from the accumulation of charred corpses.

In view of the fact that the magic cannon could not be attacked in this position, many soldiers on the city wall were constantly using arrows and heavy crossbows, pouring hot oil, and lighting flames to expel Roshan, and the contractors were also mixed in, using all their strength to attack the Kuroshio below.

Although the defensive methods such as rolling logs and rocks used in the regular defense of the city are more effective under this kind of attack, they will also relatively speed up the progress of the accumulation of corpses on the slope below, so they are not used.

Under such a stalemate, the contractors became more and more terrified as they watched the approaching demon tide below, and they could already clearly see the hideous face of the monster below, the saliva teeth, and the blood-red eyes full of greed.

The siege has been going on for almost 3 hours, but the number of monsters is still endless, and it is still pouring in.

Suddenly, the thunder light floating on the fortress wall flickered and disappeared abruptly, and the boiling thunder baking tray turned into a cold wall again.

After a moment's pause, the black tide below became frenziedly noisy, and an incomparably huge wave began to gather momentum, and it seemed that it was ready to hit the wall in a wave.

In contrast to the excited roar below, there were the contractors on the city wall, who had been fighting for three hours before, and the abrupt disappearance of the city's thunder defense was the last straw that broke the camel's back.

"It's over, it's over, it's over, it's unkeeping, it's ......"

The frightened murmur sounded everywhere, even if a few people in Beijiang and the others were still trying to attack below, they looked extremely powerless at this moment.

The waves below had surged higher and higher, gradually approaching the wall, and after losing the thunder light defense, the attacks of those arrows and fire oil and a few contractors were not worth mentioning in the huge number.

Finally, the huge and towering mountains of Roshan had been piled up to the level of the city wall, and countless monsters rushed in with excited roars, and their sharp teeth were selected to devour people.

At the moment of crisis, more than a dozen huge iron anchors smashed down diagonally from the sky, and with huge kinetic energy, the anchors smashed straight to the middle of the monster Roshan.

In an instant, flesh and blood flew sideways, and the mountain of meat was smashed into two pieces, and it collapsed and scattered, and the monsters were scattered one after another.

Along with the anchor, there were dozens of fiery figures.

A violent sea of fire began to explode in the tide of monsters, and a roar resounded through the sky.

"Demon cubs, your grandfather Thorne will play with you."

"Purgatory Legion, kill!!"

Dozens of pillars of fire as red as magma rose into the sky on the battlefield, reflecting the faces of all the contractors above.
