The United Legion naturally does not rely solely on slave creatures for their offensive power; they also have heavy firepower coverage.

Thick beams of energy, like thunderbolts cast by deities, tore through the sky and struck the Iron Curtain Walls with fierce precision.

Each hit caused the supposedly indestructible black walls to shake violently, their massive defensive runes flickering wildly, unstable in the light.

The areas directly hit instantly turned crimson, rocks melting and evaporating, leaving behind enormous craters and spiderweb-like cracks.

Troops hiding behind the walls often turned to ash along with that section of the wall; even Awakened, if they didn't react in time, would still meet their demise.

Yet the Iron Curtain Walls indeed deserved their reputation, as they were not inanimate; a vast energy seemed to flow within, and although damaged areas could not instantly recover, the structure tenaciously maintained its overall integrity without collapsing.

Additionally, there were always craftsmen among the Awakened or those with repair abilities, specifically tasked with mending the wall's damages.

Above the battlefield, energy currents had become violently visible to the naked eye, creating a catastrophic tapestry woven from the remnants of various spells, exploding fireballs, and shooting energy beams.

The roaring sounds, even from this distance, could be felt through magical projections, conveying a sense of dull, sustained impact.

Every second, countless lives were vanishing.

Duke watched all this in silence, feeling hardly any waves in his heart, only a deeper understanding of the nature of war.

This was planar warfare, a clash between civilizations, unrelated to right or wrong, only survival and conquest.

And he, along with everyone in the observation post, were merely small footnotes in this grand war, tasked with recording the moments of destruction and struggle.

Duke's gaze fell more focused on the energy monitoring magic array, meticulously recording each powerful energy burst and abnormal fluctuation.

This work, perhaps, was providing calibration parameters for the next, more deadly strike.

Several hours later.

The sounds of slaughter on the battlefield never ceased; countless slave creatures, Awakened, and demons had already fallen on this battlefield, their blood staining the land in various colors.

After hours of fierce battle, the vast wilderness before the Iron Curtain Great Wall had already turned into a flesh grinder.

The air was thick with the stench of blood, scorching, and the peculiar foul odor of various demon body fluids, mingled with the smell of gunpowder and ozone, creating a nauseating battlefield atmosphere.

The ground no longer revealed its original color, covered in layers upon layers of shattered corpses.

There were bodies of slave creatures, demons, and occasionally human limbs could be seen.

The viscous, green, blue, red, and black blood pooled into depressions, even flowing slowly, forming eerie blood puddles in low-lying areas, occasionally bubbling with a blood bubble.

But the war never stopped, and the situation on the battlefield continued to escalate.

Dozens of gigantic magic-guided cannon vehicles, like moving steel fortresses, slowly pushed into effective range under the escort of numerous heavy golems and protective witch arrays.

They were even larger than the ship cannons on the floating airships, their mouth-of-barrel accumulated energy shining blindingly, the energy waves emanating from them making Duke's heart pound, even through the monitoring witch array.

Those towering golems were all crafted by alchemists, endowed with massive, sturdy bodies, strong physical power, and high immunity to magical attacks.

Accurately speaking, they had high immunity to energy-type attacks, capable of reducing most damage caused by energy-type attacks.

Such golems on the battlefield served as solid shields, suitable for handling various chores in the field of battle.

Initially, the Toulouse territory targeted these golems, but as they found little effect and that the golems were not for offense, they shifted their focus and stopped wasting firepower on such things.

On the battlefield, those dozens of giant magic-guided cannons were already set on the edge of the battlefield.

The Toulouse territory soon noticed the commotion here and concentrated some firepower to try destroying these giant magic-guided cannons.

Even though they did not know what these were, they instinctively sensed the threat and did not want to experience their power firsthand.

But the incoming firepower, either blocked by the thick bodies of the golems or by the protective witch array, could not break through these defenses to directly attack the giant magic-guided cannons in a short time.

Once these giant magic-guided cannons were ready, they started firing promptly, without delay, leaving no room for Toulouse to prepare.

With a series of loud roars, dozens of destructive energy torrents capable of tearing the firmament launched like spears of judgment, all striking the same area of the Iron Curtain Walls simultaneously.

At that instant, the whole battlefield seemed to fall silent.

Following that was an indescribably intense explosion and energy outpouring.

The section of the wall under concentrated attack, the surface defensive runes shattered like fragile glass, unable to counter such concentrated and terrifying kinetic and energy impact.

The black boulders were no longer just melting; they vaporized, annihilated.

A gigantic, nearly penetrating breach was forcibly blasted open, instantly vaporizing the defenders, ballistas, and even a few gigantic fixed demons hiding behind.

Thick smoke, debris, and energy remnants rose like a mushroom cloud, this destructive strike seeming to toll the death knell for Toulouse's defense line.

The moment the breach appeared, the slave creature legion, long awaiting, let out an even more frenzied roar, surging towards the gap like a group of sharks smelling blood.

The defenders in other parts of the wall attempted to support the breach, but the United Legion's ranged firepower seemed to have eyes, suppressing them with precision.

The floating airships concentrated their firepower, hindering the Awakened attempting to seal the breach from approaching.

Toulouse's casualties rapidly increased. Although the Awakened had diverse and strong abilities, their stamina and energy were not inexhaustible.

Faced with such severe saturation attacks and seemingly endless slave creature assaults, the insignificance of individual strength was infinitely magnified.

One Awakened after another fell due to exhaustion of energy, a delayed reaction, or simply bad luck, succumbing to arrows, evaporated by energy beams, or torn apart by the frenzied slave creatures rushing through the breach.

The casualties of Toulouse's demons were equally severe, with those giant flying demons continuously shot down, crashing to the ground like meteors.

The spider-like demons on the walls were heavily cleared, and the giant fixed demons, once exposed, were soon targeted by the United Legion's heavy artillery, reduced to scorched remnants amidst their wails.
