"Vanguard, advance!"
The Taicang Quasi-Monarch coldly gave the order.
From within the allied army, a full thousand divine ships emerged.
Each ship was manned by three Great Powers, with numerous Heavenly Kings and Saints serving as soldiers and officers. They tore through the void, each harboring extremely astonishing Formation Arrays.
This vanguard force was countless times more terrifying than the Imperial Punishment Legion of the alien army from years past.
Numerous terrifying attacks rained down incessantly upon the Human Pass Fortress.
Though described as rain, each attack was capable of shattering mountains and rivers for tens of thousands of li. Concentrated together, their power was unimaginable.
However, the Human Pass Fortress had long been repaired, and numerous Defense Formations had been established, forming layer upon layer of light screens. Runes flickered, completely blocking all these terrifying attacks.
Upon the Human Pass Fortress stood Qin Wu, the commander of the human army. His expression unchanged, he ordered, "First God-Slaying Legion, prepare!"
Boom! Boom! Boom!
Behind the Human Pass Fortress, numerous fearsome divine ships appeared, along with dozens of terrifying star weapons. The six largest golden star weapons had diameters exceeding a hundred thousand li, all equipped with fearsome divine energy cannons aimed at the outside world.
These were Great Power-level God-Slaying Cannons, while the golden stars boasted what were called Divine King-level God-Slaying Cannons, specifically designed to target supreme experts of the Divine King level.
The original five God-Slaying Legions, after joining the Chaos Heavenly Mansion, were divided into the First through Fifth God-Slaying Legions.
Furthermore, each of the five God-Slaying Legions possessed its own corresponding special characteristics, ranked according to the five elements: metal, wood, water, fire, and earth.
The one appearing now was the First God-Slaying Legion, proficient in the path of metal and serving as the primary offensive God-Slaying Legion.
"God-Slaying Cannons, fire!"
Following Qin Wu's roar, beams of supremely dazzling light shot forth from the numerous God-Slaying Cannons of the First God-Slaying Legion.
Though called beams of light, they were actually condensed from boundless Great Dao runes, containing unparalleled world-destroying power. In the blink of an eye, they passed through the layered defenses of the Human Pass Fortress without the slightest obstruction, because the fortress's Formation Arrays were designed to block attacks from the outside, not the inside.
"Vanguard forces, evade!"
The Taicang Quasi-Monarch shouted, but it was too late for evasion. The sky-filling God-Slaying beams instantly pierced through one warship after another, causing them to explode directly.
In an instant, over a third of the divine ships were hit, with more than half of those struck exploding. Casualties were countless, and the defensive Formation Arrays on the ships offered little protection.
Among them, the Divine King-level God-Slaying beams fired from the six golden stars, containing the power of Divine King Great Dao origin, were especially devastating. Each beam directly blasted apart dozens of divine ships, achieving a truly astonishing battle record.
In just the first clash, the allied army's vanguard suffered heavy casualties. While this was only a minor loss for the allied army as a whole, it was a poor opening move that dealt a significant blow to their morale.
The expressions of the numerous allied Quasi-Monarchs darkened slightly. They understood the humans' strategy: not to act at all, but when they did, to unleash the most fearsome attacks.
"Good, good, good! The human race truly has resolve. Since that's the case, don't blame our allied army for being ruthless."
The Taicang Quasi-Monarch uttered three 'good's in succession, his eyes narrowing with a cold glint. He roared, "World-Destroying Assault Divine Cities, deploy! Attack the Human Pass Fortress!"
Visible to the naked eye, from the rear of the allied army, one terrifying immortal ancient city after another rose into the air. Each was as massive as a star and radiated an extremely fearsome aura, surpassing that of a Great Power.
Upon the Human Pass Fortress, the expressions of the human experts changed. The old Quasi-Monarch Xiao Ding also looked grim. "Divine King-level ancient cities, transformed into assault divine cities. And over a hundred of them. This allied army is truly willing to invest heavily."
Divine King-level ancient cities held the same status within a Divine King's inner world as Imperial Cities and Sovereign ancient cities did within Emperor Realms and Sovereign Great Worlds. They were the central divine cities within a Divine King's origin inner world.
In the future, they would gradually evolve into Sovereign-level ancient cities, even becoming existences akin to Imperial Cities. They held immense significance for Divine Kings, serving as their headquarters, inscribed with numerous Divine King-level Dao patterns, secret patterns, and Formation Arrays, possessing a portion of Divine King-level power.
Even a Divine King would need considerable time to breach the defenses of a Divine King-level ancient city.
But now, over a hundred Divine King-level ancient cities had been transformed into assault divine cities, likely possessing peerless power comparable to that of Divine Kings.
Over a hundred World-Destroying Assault Divine Cities were equivalent to over a hundred Divine Kings launching a forceful assault on the Human Pass Fortress.
Boom! Boom! Boom!
Layer upon layer of heavenly curtains were torn apart. Massive Defense Formations glowed, flickering with numerous Great Dao runes as they resisted the continuous attacks from these assault divine cities.
"Hmph, this defense is indeed far stronger than before. But don't think you can hold out."
From within the allied army, eighteen Quasi-Monarchs made their move, unleashing eighteen Cang Dragons. Each Cang Dragon was over a hundred thousand li in size, containing the rolling power of Quasi-Monarchs, terrifyingly fearsome and far surpassing the power of these World-Destroying Assault Divine Cities.
Boom! Boom! Boom!
Visible to the naked eye, under the forceful assault of the eighteen Cang Dragons, the layered Defense Formations were easily breached. Combined with the attacks from the numerous World-Destroying Assault Divine Cities, the Human Pass Fortress was soon left with only its final heavenly curtain, which was also its most solid layer.
"Break!"
The eighteen Quasi-Monarchs roared, channeling their rolling Quasi-Monarch power into these Cang Dragons. Instantly, their might increased by more than a notch. They roared wantonly, battering the final heavenly curtain until it swayed precariously, continuously fading and nearly on the verge of complete shattering.
Finally, after this assault persisted for a moment, the final heavenly curtain was completely breached.
Whoosh!
The heavenly curtain shattered into countless fragments that fell like rain. The Human Pass Fortress was now completely exposed before the world.
Although the eighteen Cang Dragons, formed from condensed Quasi-Monarch divine power, had expended much of their energy breaching the heavenly curtain and were no longer what they once were, they remained fearsome, capable of devouring Divine Kings as they charged toward the experts on the Human Pass Fortress.
"Mere Cang Dragons formed from condensed power dare to act so fiercely?"
Qin Wu snorted coldly. With a flip of his palm, it transformed into a sky-covering, heaven-propping giant hand, descending from the heavens with peerless Quasi-Monarch power, smashing down upon the eighteen Cang Dragons.
Boom! Boom! Boom! Boom! Boom! Boom!
With a single slap, all the Cang Dragons completely disintegrated and crumbled, showcasing the peerless cultivation of Qin Wu, a Great Perfection Quasi-Monarch.
The expressions of the allied army's Quasi-Monarchs remained unchanged. While these Cang Dragons were fearsome, that was relative to Divine Kings. They posed little threat to Quasi-Monarchs, weren't real entities, and thus were not difficult to destroy.
"Heh, Qin Wu, this time your human race is completely exposed before our allied army. This Sovereign will see just how your human race intends to resist our allied army this time!"
The Taicang Quasi-Monarch of the Divine Emperor Clan sneered. He was extremely powerful, his entire body overflowing with supreme, majestic Quasi-Monarch radiance. A slender ancient sword appeared in his hand, its sword light piercingly sharp.
"Allied army, advance on the human race! This time, we swear to seize the Tomb of the Fallen Heaven!"
Following his roar, the allied army behind him suddenly erupted with an astonishing aura that spread majestically throughout the entire Eighth Heavenly Realm Ancient Domain, its scale truly staggering.
The vast, mighty allied army advanced. Countless experts streaked across the sky, launching a full-scale assault on the Human Pass Fortress at the breach of the Emperor Realm, their sights set on the distant Tomb of the Fallen Heaven.
