That heartbeat…It was terrifying—echoing as though the very world itself was pulsing with it.
The rhythm was agonizingly slow. One beat might take ten minutes... or even hours.
Sometimes, days passed between pulses.
There was no question—this was the sign of immense, ancient life.
The sound came from primeval demon mountains, from jungles, from underground, from the seafloor, and even from the clouds above.
"So this really is the Primeval Demon Domain," Yi Tianxie murmured, his gaze serious.
"This place has become a graveyard. The ancient demonic beasts have all fallen into slumber, becoming the mountains, rivers, and terrain."
"They've been asleep for who knows how long… yet they're still alive. Their vitality remains strong."
"That's the terrifying resilience of primeval demon beasts."
Now, with the passage to the Eternal World opened, the flow of its energy had begun to stir the slumbering titans.
And once they awoke… they would follow the scent of life to cross the rift into the Eternal World.
For these beasts, growth and evolution required slaughter and devouring massive amounts of life force.
Their very essence was destruction.
Ruination was their honor.
Yi Tianxie could already sense the heartbeats accelerating.
Their aura was beginning to intensify.
Once awakened, these would be unspeakably powerful monsters.
Each one of them was no weaker than the Nine-Tailed World-Destroying Demon Dragon from before.
That beast had only awoken because the passage had opened right next to it, stirring it with Eternal World energy.
So it had immediately crossed over—appearing within Great Yi's domain.
"Interesting," Yi Tianxie smirked."But this Primeval Demon Domain has already been... prepared by me."
"No matter how many awaken, if they dare to step through the gate… they will become nourishment for the Beast Gate."
"Their essence will fuel the sect—strengthen it beyond comprehension. If we can consume them all…"
"We might even shatter Innate Spirit Treasures, or dominate the world."
Yi Tianxie had no real attachment to the Primeval Demon Domain.To him, all the beasts here were resources.They would become food for his cultivation.
"So… this massive seal—this must have been cast by a top-tier Eternal Night demon god."
"They clearly tried to lock this entire domain down, to prevent the beasts from escaping."
"Even the Eternal Night World views this place as a forbidden zone."
"But this seal… it can't stop me."
His Ten Thousand Evils Dao Body allowed him to walk freely through all barriers.
No seal, formation, or restriction could truly trap him.
He also possessed a special weapon—the Blood Moon Altar—a core component of his Ten Thousand Evils Altar.
This altar wasn't forged in the Eternal World.It was forged using the Blood Moon of the Eternal Night, with the help of a strange artifact from the Eternal Night battlefield: the Blood Spirit Stone.
This allowed the altar to mimic the energy of Eternal Night itself.
Thus, Yi Tianxie could completely mask his aura and identity—making him undetectable in this foreign realm.
So long as he didn't reveal himself, no one would know where he truly came from.
Just as he was about to leave the Primeval Demon Domain and head deeper into Eternal Night—
A flash of golden light caught his eye.
"Hmm? What's that?" he said with curiosity.
He teleported instantly to the source of the glow.
Before him stood a massive demon mountain, weathered and aged beyond comprehension.
Most of it was dark and dull—but at a certain point, the wind had eroded the surface, revealing a golden sheen beneath.
Not just any gold—it was flawless, smooth and lustrous, with not the slightest imperfection.
"Fascinating…"
With a wave of his hand, Yi Tianxie swept away the sand, inch by inch.
Soon, an immense structure emerged from the earth.
"A pyramid."
Yes.
It was a giant golden pyramid, revealed in full after the sand had been stripped away.
The pyramid was formed from a single seamless piece, though it showed clear signs of battle—gashes, cracks, and claw marks everywhere.
Its apex had been cleaved clean off—a chunk simply missing.
Despite the damage, the majesty and grandeur of the pyramid still shone through.
It was a miraculous creation.
Yi Tianxie's gaze grew sharper.
"This aura… it feels familiar. Wait… this isn't just a pyramid—"
"It's an Eternal Heaven Ark!"
His expression turned grave.
Yes. He could sense the distinct aura of the Eternal Lotus Seed, the core component of all Eternal Heaven Arks.
Great Yi's own Xuanhuang Immortal City was technically one such ark, albeit in an alternate form.
But this one… this was the real thing.
According to ancient records, during the last epoch, the Eternal faction had launched a grand counterattack into the Eternal Night World.
A vast expeditionary army marched forth.
No one knew how the war ended, but it had clearly been devastating.
Even the Eternal side suffered enormous losses.
Many of their top experts died on foreign soil.
The Eternal Heaven Arks were the main carriers in that war—bearing soldiers, weapons, and divine energies.
Countless arks were destroyed by the top-tier demon gods of Eternal Night.
Some were recovered. Others were lost, either seized by enemy hands or buried in forbidden zones.
No one knew how many remained.
Now—standing before Yi Tianxie—was one of those fallen arks.
"What incredible fortune…"
"To step into the Eternal Night and immediately discover a lost Heaven Ark…"
"If it's still intact—and if its Eternal Spirit remains—we might be looking at a peerless opportunity."
Heaven Arks of this caliber were the highest grade—only the strongest forces possessed them.
If he could revive it… his strength would skyrocket.
He examined the pyramid closely.
It was still seamless—without joints or entry points.
Normally, it would be impossible to enter.
But now… the broken apex left behind a natural breach—a gaping hole at the top.
No barrier stopped him.
Yi Tianxie entered without hesitation.
Inside, he immediately saw what made this pyramid different.
It wasn't just hollow—it was a mountain of gold, filled with vast chambers and palaces carved into its bulk.
The construction was magnificent.
Even more astonishing—divine sense could not penetrate the structure.
The pyramid's shell blocked all external probing.
From the top entry point, he dropped into the central core—a vast palace complex.
There was a plaza.
Structures.
And a Heavenly Pool.
And in the center stood—
A massive Eternal Divine Furnace.
But… the pool was dry, and the furnace… damaged.
Its divine light was gone—its power extinguished.
"The Eternal Divine Furnace—the heart of the entire Heaven Ark…"
Yi Tianxie's eyes flashed.
He rushed forward, placed his hand on the furnace, and poured in his energy, probing its condition.
The results weren't great.
The Eternal Spirit that governed the ark was severely damaged.
Not gone—but barely hanging on, slumbering in deep silence.
Many internal systems were destroyed.
Still… this ark had once specialized in defense, but it also had immense offensive potential.
Its most terrifying feature was the ability to summon legions of undead.
In the Eternal Night war, it had been a true engine of destruction.
Yi Tianxie's heart stirred.
A lost warship of the Eternal Expeditionary Force…
Now lying in his hands.
Perhaps still salvageable.
A deadly trump card, waiting to rise again.
