However, what truly caused the three Immortal Kings to change countenance was the origin of the Seven Dark Demon Gods!
Because the name of the Chaos of the Ancient Seven Heroes was far from obscure; on the contrary, in the boundless ages past, they were once extremely famous, their might shaking the entire Chaos Sea for many epochs.
For they were once the seven extremely powerful Chaos Demon Gods of the Chaos Sea.
Chaos Demon Gods, as the name implies, are demonic godly existences born from chaos.
Chaos Demon Gods are divided into Xiantian and Houtian.
Houtian Chaos Demon Gods are, in reality, the most familiar kind in the contemporary Chaos Sea, and can also be called Chaos Holy Spirits.
Regarding Chaos Holy Spirits, many know that they gestate in chaos for millions, tens of millions, or even hundreds of millions of years—boundless ages—before finally emerging into the world. They are innately powerful, existences of Great Perfection Supreme Geniuses, and have great hope of attaining the Dao and becoming Supreme Ones as they grow.
Historically, it is not uncommon for Chaos Holy Spirits to attain the Dao and become Supreme Ones.
As for Xiantian Chaos Demon Gods, they can be said to be the ultimate chaos beings born together with the opening of the Chaos Sea. In essence, they are far more powerful and terrifying than the Houtian Chaos Demon Gods, the Chaos Holy Spirits.
If Chaos Holy Spirits are innately powerful, at the level of Great Perfection Supreme Geniuses, and have great hope of attaining the Dao and becoming Supreme Ones as they grow, then Xiantian Chaos Demon Gods are already existences at the Supreme One level from the moment of their birth, and moreover, Supreme Ones who attained the Dao through their physical bodies.
They possess peerless, indestructible, and immortal physical bodies that even Supreme Ones would regard with considerable caution.
Because they are born with lifespans equal to the heavens, their lifespans are infinite. As time passes, Xiantian Chaos Demon Gods will only grow stronger.
From the opening of the Chaos Sea to the present day, who knows how many epochs have passed. Basically, any Xiantian Chaos Demon God that survived eventually became colossi from antiquity, and some even reached the level of Primordial Giants.
This type of Xiantian Chaos Demon God belongs to the category of innate Supreme Ones, possessing unparalleled Xiantian advantages.
Of course, Heaven is fair. While bestowing upon Xiantian Chaos Demon Gods the Xiantian advantage of innate physical body Supreme Ones, on the other hand, their comprehension of the Great Dao is hindered because their physical bodies are too powerful, leaving them significantly lacking.
Precisely because of this, Xiantian Chaos Demon Gods require the accumulation of time, often needing to expend over ten epochs or more to gradually become colossi from antiquity.
Moreover, the strength of their physical bodies also leads to the souls of Xiantian Chaos Demon Gods not being powerful enough; they are relatively weaker compared to other cultivators of the same level who achieved their strength through cultivation.
This is also one of the flaws of Xiantian Chaos Demon Gods.
But even so, as Xiantian Chaos Demon Gods grow with time, they can similarly compensate for their various flaws, ultimately becoming one of the supreme overlords of the Chaos Sea.
The Chaos of the Ancient Seven Heroes were all Xiantian Chaos Demon Gods born at the opening of the Chaos Sea. Because they were born simultaneously in the same place, their relationship was extremely close, as intimate as brothers, hence they were known as the Chaos of the Ancient Seven Heroes.
Before their disappearance in the past, aside from their leader 'Yan' being a colossus from antiquity, the other six brothers were all Quasi-Giant level. In the early days of the Chaos Sea, due to a momentary grievance, they nearly caused an ancient chaos universe to be destroyed because of them. They were an extremely powerful group.
It's just that later, the Chaos of the Ancient Seven Heroes suddenly vanished, and no one knew their whereabouts.
Who would have thought they were actually here in this Eternal Night Land.
And, after so many epochs, the seven Xiantian Chaos Demon Gods have all successively become colossi from antiquity. Their leader 'Yan' has even become a Primordial Giant level existence, hailed as one of the most powerful Chaos Demon Gods throughout history.
Immortal King Haozun's brows furrowed deeply. "I never expected it to be the Chaos of the Ancient Seven Heroes from the boundless ages past. They are actually still alive, and have all reached the level of colossi from antiquity. This is a huge problem now."
The leader of the Chaos of the Ancient Seven Heroes was none other than the most powerful among the seven Xiantian Chaos Demon Gods, the Flame Demon God. Staring at the Heavenly Gate, and especially at the Donghuang Bell, he revealed a look of fervor. "This seems to be the Donghuang Bell, the Dao weapon of that old fellow Donghuang from the past. I never thought it still existed in the world. Moreover, this Heaven-Reaching Bridge has the aura of Donghuang's origin essence; it is a Heaven-Reaching Bridge condensed from a wisp of his true self. Could it be that old fellow Donghuang is trapped within the Eternal Unknown Land, and his descendants are trying to use a wisp of origin left by Donghuang to rescue him?"
Hearing this, the three Immortal Kings and the many powerhouses within Donghuang Sacred City all changed countenance. The Flame Demon God had actually guessed everything.
The Flame Demon God glanced back at the Eternal Unknown Land, the place pierced by the Heaven-Reaching Bridge, then let out a sinister laugh. "Very well. That old fellow Donghuang is lost within. Wanting to return won't be so easy. Today, this Demon God will take away his Dao weapon, then invade the Primordial Immortal Realm!"
"Agreed!"
"Hahaha, big brother, great idea!"
"Invade the Primordial Immortal Realm, make it the territory of our Chaos of the Ancient Seven Heroes!"
...
The other six Xiantian Chaos Demon Gods also revealed similarly fervent gazes.
The Chaos of the Ancient Seven Heroes, the seven Xiantian Chaos Demon Gods born at the opening of the Chaos Sea, set their sights on the Primordial Immortal Realm.
Boom! Boom! Boom! Boom! Boom! Boom!—
The Chaos of the Ancient Seven Heroes, each riding a great ferocious mount, crushed through space-time with a roar, charging towards the Heavenly Gate.
That was the main portal connecting the Eternal Night Land and the Primordial Immortal Realm, a place the Chaos of the Ancient Seven Heroes were bound to go.
"Not good! The Chaos of the Ancient Seven Heroes are coming! We must hold them off!"
Immortal King Jiuyou's expression changed, immediately shouting. He joined the other two Immortal Kings in taking action to block the Chaos of the Ancient Seven Heroes.
Moreover, the Donghuang Bell tolled, sweeping out beams of Immortal Venerable One light, bombarding the Chaos of the Ancient Seven Heroes!
But the Flame Demon God was the leader of the Chaos of the Ancient Seven Heroes, a Primordial Giant-level titan of the Chaos Sea, terrifying and peerless. Wielding a Green Dragon Crescent Blade, he directly cleaved apart the beams of Immortal Venerable One light one after another, rendering them unable to harm him in the slightest.
After all, Immortal Venerable Ones are on par with Primordial Giants. The Donghuang Bell was ultimately just a Dao weapon, while the Flame Demon God was his true self in the flesh, naturally far more terrifying.
In less than a moment, the Flame Demon God had already led the Chaos of the Ancient Seven Heroes to kill their way to the Heavenly Gate. Even the Dark True Dragon and the Dark Demon Tiger followed, making a total of nine Dark Giants. What a terrifying lineup this was, enough to easily crush and annihilate an ancient chaos universe.
The three Immortal Kings—Taiyu, Jiuyou, and Haozun—changed countenance, immediately joining forces to activate the Donghuang Bell.
The Donghuang Bell revived to its fullest extent, meeting the charge of the Chaos of the Ancient Seven Heroes.
The bell body became incomparably huge, blotting out the sky and covering the sun, filling every inch of space at the Heavenly Gate, blocking the path of the Chaos of the Ancient Seven Heroes' invasion into the Primordial Immortal Realm.
The Flame Demon God snorted coldly, swinging the Green Dragon Crescent Blade. With a rumbling roar, the Donghuang Bell had all its Immortal Venerable One light beams shattered by a single slash. The blade fell upon the bell body, producing a deafening clamor that echoed through the myriad heavens of antiquity.
Clang!—
The Donghuang Bell was directly sent flying, crashing into the Heavenly Gate and heavily striking the three Immortal Kings.
Boom! Boom! Boom!—
The three Immortal Kings' expressions changed drastically. They immediately exerted their Immortal King power to withstand the blow, only hurriedly retreating several hundred thousand li without suffering injury.
At the same time, the Chaos of the Ancient Seven Heroes pressed their attack!
