The Origin Saint Race's sudden assault on the Primordial Immortal Realm was something no one had anticipated.
Although the Origin Saint Race did not originate from a Chaos Ancient Universe, their origins were immense, involving the legendary Land of Origin. It was rumored that the Origin Saint Race was a race that came from the Land of Origin, consisting of eight clans, also known as the Eight Origin Clans. Of course, countless eons ago, the Profound Clan betrayed and left the Origin Saint Race. Now, the Origin Saint Race only had seven clans remaining. Even so, the Origin Saint Race remained extraordinarily powerful, considered one of the mightiest forces in the Chaos Sea, in no way inferior to the Primordial Immortal Realm, the Alien Ancient Universe, or the Pangu Universe, as they also had an Overlord-level existence presiding over them.
Moreover, multiple epochs ago, the Origin Saint Race was the strongest overlord clan that ruled the entire Chaos Sea, naturally incomparably powerful.
Now, no one had expected that the former overlord clan of the Chaos Sea would suddenly assault the current overlord, the Primordial Immortal Realm, directly tearing open the Immortal World's cosmic barrier, collapsing multiple Immortal King Passes, and appearing with overwhelming force.
The Chaos Sea was shocked.
The Origin Saint Race had actually colluded with the Alien Ancient Universe!
In the Northern Wastes of the Primordial Immortal Realm, bloody light surged. The several Immortal Kings guarding this place were shattered to pieces. Quasi-Immortal Kings, True Immortals, and those below the Supreme One level suffered countless casualties. Vast stretches of the boundless Northern Wastes were devastated, with an incalculable number of Immortal World beings slaughtered.
Multiple Giants of the Origin Saint Race led armies in a forceful invasion, causing immense slaughter among the Immortal World's countless living beings. For a time, casualties were extremely heavy.
"Origin Saint Race!"
A furious roar exploded!
Within the Primordial Immortal Realm, beams of immortal light shot into the heavens above. On the Thirty-Three Heavens, immortal radiance was boundless, spreading across all heavens, causing the stars of the myriad heavens to tremble.
One majestic, peerless figure after another appeared—Immortal Kings and Immortal Venerable Ones from across the Immortal World, all awakening and rushing over immediately, their icy gazes sweeping toward the Origin Saint Race, filled with killing intent.
The Origin Saint Race actually dared to declare war on the Primordial Immortal Realm!
Termination Immortal Venerable said coldly, "Today, since the Origin Saint Race dares to declare war on our Primordial Immortal Realm, they must pay the corresponding price!"
A first-generation Giant of the Origin Saint Race, who was precisely the former Heavenly Clan Patriarch from ages past, was extremely powerful, in no way inferior to Termination Immortal Venerable. His rolling might of ten thousand eons annihilated the surrounding space-time, dragging down star domain after star domain in the Immortal World's starry sky into oblivion, permanently erasing their starlight. He sneered, "A price? The price will be the collapse of the Immortal World! Today, my Origin Saint Race will replace it and become the new ruling clan of the Immortal World!"
Today, the Origin Saint Race dared to invade the Primordial Immortal Realm, having never intended for a peaceful resolution from the start.
Moreover, they had long been secretly colluding with the Alien Ancient Universe.
This was one of the reasons the Alien Ancient Universe dared to declare war on the Chaos Sea, and also the reason the Origin Saint Race dared to declare war on the Primordial Immortal Realm.
Whether it was the Origin Saint Race or the Alien Ancient Universe, both were among the most powerful forces in the Chaos Sea, capable of sweeping through many Chaos Ancient Universes.
The Chaos Sea was in great upheaval. This was a great war between the former overlord force and the current overlord force.
"Your Origin Saint Race has quite the nerve. Do you truly think this is still the era when you ruled the Chaos Sea? The current you were crippled back then by the Immortal Ancestor, the Heavenly Emperor, and various forces, far from your former glory. And don't forget, those who dealt with your Origin Saint Race back then also included Shidai and the Alien Ancient Universe," Termination Immortal Venerable snorted coldly.
"That's all in the past. The present is what matters most," said the Heavenly Clan Patriarch.
"Then let's fight! This venerable one wants to see how much of your former majesty the Origin Saint Race still possesses today!"
Under Termination Immortal Venerable's lead, the various Immortal Venerable Ones and Immortal Kings advanced together. One towering, heaven-propping, earth-supporting majestic figure after another, carrying boundless immortal light, struck across the myriad heavens, charging toward the Origin Saint Race.
An ultimate war involving the entire Primordial Immortal Realm, and even the Chaos Sea, erupted just like that.
Others also never expected the Origin Saint Race to strike against the Primordial Immortal Realm at this time, and it seemed they had a significant relationship with the Alien Ancient Universe.
Within the Immortal World, the Forty-Nine Immortal Pass Secret Realms manifested. Terrifying figures appeared one after another—some with shifty, rat-like eyes, some with cinnabar marks on their foreheads. They were the Immortal World's Half-Step Overlords, unimaginably powerful, overlooking the battlefield and gazing into the distance behind the Origin Saint Race. Their expressions were somewhat gloomy as one said, "We never expected your final choice would be to stand on the alien side..."
Behind the Forty-Nine Immortal Pass Secret Realms, several blurry, terrifying figures also appeared—the Origin Saint Race's Half-Step Overlords. One said indifferently, "It's nothing. We merely wish to rewrite the order. My Origin Saint Race is destined to once again become the overlord of this Chaos Sea."
"Is that so?"
The shifty-eyed Immortal Dao Half-Step Overlord said coldly, "This venerable one also wants to know if your Origin Saint Race has the capability!"
"Then we shall wait and see!"
The great war between the Primordial Immortal Realm and the Origin Saint Race erupted.
"Let's go, fight in the Chaos Sea!"
An Immortal Dao Half-Step Overlord spoke, but an Origin Saint Race Half-Step Overlord said, "No need. Right here in the Primordial Immortal Realm is fine. Coincidentally, the Immortal Dao's rules in the Primordial Immortal Realm are too deeply ingrained. They need to be destroyed, to use this great war to shatter its foundation!"
The Immortal Dao system had completely integrated into the Immortal World's origin, affecting the cultivation of other systems. Otherwise, even if they entered the Primordial Immortal Realm, over time, they might gradually change their cultivation methods and become members of the immortal cultivators. Therefore, they needed to directly destroy the foundation of the Immortal Dao system.
Hearing this, the Immortal World's powerhouses all had ugly expressions. This was truly a heart-piercing move by the Origin Saint Race.
"Fine, fine, fine!" said the Immortal Dao Half-Step Overlord with the cinnabar mark on his forehead coldly. Back in the day, he had followed the Immortal Ancestor into that battle. Now, he wanted to see how much of the Origin Saint Race's former capability remained.
At the same time, the cosmic barrier of the Primordial Immortal Immortal World manifested Immortal Dao imprints one after another. These were the Immortal Dao marks left by all those who had achieved immortality throughout the ages, resonating with the Immortal World's origin. Furthermore, Immortal Dao grand formations appeared one after another, covering the entire Primordial Immortal Realm, stabilizing it to avoid the war becoming too devastating and causing the slaughter of countless living beings.
The terrifying war between the two great forces directly erupted, shaking past and present.
In the Primordial Immortal Realm, vast domain after vast domain was directly devastated. Billions of stars in the starry sky were annihilated, transforming into the most brilliant fireworks blooming with their final radiance.
The Northern Wastes of the Immortal World, comparable to the Donghuang Domain, became the most terrifying battlefield.
At the same time, the Origin Saint Race's secret realm worlds were also affected. Boundless Immortal Dao power blasted out, annihilating the heavens, and also directly shattered many of the Origin Saint Race's secret realm worlds.
Soon, bloody light surged to the heavens as Supreme Ones fell, whether from the Primordial Immortal Realm or the Origin Saint Race.
Even more, not long after, powerful beings like Immortal Kings also fell, with countless phenomena appearing, only to be instantly annihilated into dust by the residual shockwaves of the supreme existences' battle from both sides.
Giants of the Origin Saint Race also fell.
Such was the devastation of war.
