"Screech!"

The piercing cry of the eagle echoed through the void, and even though the wings of the three-headed Earth Demon hadn’t arrived yet, the ear-splitting sound waves were like an invisible thunder, attacking the Sea of Consciousness of Gu Yuan and his companion.

"Roar!"

Gu Yuan’s Divine Thought surged out, transforming into a massive Three-Eyed Thunder Flood Dragon, roaring angrily and suppressing the eagle’s cries directly.

Even if the three-headed Earth Demon screeched together, they could not overpower the might of the Thunder Flood Dragon.

"Boom!"

But at this moment, the figure on the three-headed Eagle Demon had already made a move.

Three gigantic fireballs, carrying dense black smoke, streaked across the void like black meteors and fell down with a mighty momentum.

"Reverberate!"

Gu Yuan softly murmured, and from his Dantian, a transparent and bizarre Dharma Seal suddenly flew out, drawing upon the Spiritual Qi, and a transparent bubble seemed to rise around him, isolating him from the environment, enveloping him within.

"Boom!"

Two black fireballs arrived abruptly, but they passed straight through Gu Yuan, falling on the island, kicking up massive dust and smoke.

The other fireball was directly aimed at Cen Qingqing.

Gu Yuan could have activated the Leaving Realm Clarity Seal to encompass Cen Qingqing together within it and evade this attack, but he remained indifferent, apparently lacking the mana to support such a large protection.

"Boom!"

Cen Qingqing, witnessing the situation, did not say much, merely swung her hand, and an unusual Dharma Seal, resembling a Flood Dragon, suddenly flew out. The heavens flashed with lightning, instantly condensing into a Thunder Flood Dragon about a yard long.

The Flood Dragon suddenly swam, with a flick of its tail, sending the black fireball flying. Not only that, the Thunder Flood Dragon opened its mouth to spit, and a bolt of lightning thundered out, striking the figure on the Demon Bird.

"Bang!"

The lightning sparkled incessantly, and a burnt smell seemed to permeate the air, yet the figure remained standing on the Demon Bird’s back, completely unmoved.

"This is..."

Gu Yuan and Cen Qingqing’s eyes were sharp as they simultaneously looked into the sky, their hearts beset with inexplicable astonishment.

The three-headed Earth Demon and the three Foundation Establishment Cultivators weren’t enough to surprise Gu Yuan; what astonished him was the "person" standing on the back of the Demon Bird.

Perhaps that could no longer be called a person.

Skin dark as charcoal, eyes pitch black, features ferocious, fangs protruding, with two large bone wings on their back, black as ink, surrounded by an inexplicable black aura.

Only the limbs retained a humanoid form, reflecting traces of an original appearance.

But the spark in the eyes had lost all spiritual nature, resembling a zombie.

The lightning struck upon it, leaving it charred and black, but it remained motionless, as if the attack hadn’t touched its own flesh.

The most crucial thing was, in the mist covering the island, an abundant amount of black gas was continuously pouring into this person’s body, and the charred and ferocious wounds from the lightning were slowly healing, as if they had never been injured.

And the Demon Bird at the feet of the three "humans" also had feathers black as ink, with talons and fangs as sharp as spikes, giving off an inexplicable sense of strangeness.

"Kill all intruders!"

Among the three, one with pupils as black as pitch, showing no emotional fluctuation, Gu Yuan even felt that these three had lost their minds and could no longer be called humans.

But the lips moved slightly, yet emitted human-like sounds, though the voice was cold, like shards of ice, devoid of any warmth.

"Screech!"

The Demon Bird beneath the three suddenly screeched, carrying the three with extreme speed towards Gu Yuan and Cen Qingqing.

In the dense black forest, countless demon creatures with bloodshot eyes arrived together.

From the depths of the island, a terrifying roar seemed to resound, with a presence seemingly more frightening than the Demon Bird before them.

"Rumbling!"

More than that, the island shook, as if some gigantic creature had awakened, stepping forward.

Gu Yuan’s expression changed slightly.

This island seemed to be more perilous than anticipated.

"Daoist brother, this island is perilous; my father must have used a mystical shortcut, definitely not entering the island recklessly."

"Please protect me for a moment; I need to find this method!"

Listening to the bizarre sounds from the depths of the island, Cen Qingqing’s face turned slightly pale, then clasped her hands in a spell, seemingly sensing something, and turned to shout at Gu Yuan.

"Please hurry, the demons from the island’s depths are coming!"

Gu Yuan pointed with his finger, and eighteen sword lights whirled upwards like lively dragons, splitting into three directions, blocking the advancing three-headed Demon Bird and the three eerie figures.

"Boom!"

Countless black flames surged, like a frenzied dance of serpents, spreading from the Demon Bird and the figures’ hands.

Gu Yuan’s sword light shone brightly, like invisible thunder, but the three figures, fearless beyond measure, had their bodies sliced by Sword Qi, leaving wounds that were immediately filled with swirling black smoke, flawlessly healing in the blink of an eye.

The most crucial problem was, eighteen sword lights, dazzlingly sharp, capable of slicing through anything, yet split in three directions left only six, difficult to resist the fearless pair of humanoid demon creatures.

"Reverberate!"

Gu Yuan could only step back, sticking close to Cen Qingqing, then activating the Leaving Realm Clarity Seal, summoning an invisible shield to protect the two.

"Hiss hiss hiss!"

But within the black forest, innumerable demon creatures, glaring with bloodshot eyes, relentlessly surrounded them.

Eventually, numbers can overwhelm strength.

The light of the Leaving Realm Clarity Seal rapidly dimmed, with Gu Yuan’s mana flowing out incessantly.

Not only that, a massive black serpent, twenty yards long, had already coiled its way over, its presence stronger even than the terrifying Demon Bird and weird figures before them.

The Leaving Realm Clarity Seal seemed unable to withstand.

Meanwhile, Cen Qingqing had already sat cross-legged behind Gu Yuan, eyes closed, holding a blood-red Soul Lamp in her hands, muttering incantations.

A golden Dharma Seal revolved endlessly before her body, countless brilliant Dao Patterns shining brightly, as if transforming through infinite cycles in an instant.

"Vast Sea Qi Seal!"

Seeing this, Gu Yuan, with reluctance, could only activate another Dharma Seal.

In an instant, numerous water vapors surged like great rivers, pushing back all attacking demons.

Gu Yuan cultivated the Three Synergies Refining, each Foundation Establishment requiring the cultivation of a formidable Dharma Seal, though he seldom used them during ordinary times.

Not because he feared dispelling this seal might expose his secret of possessing three Dao Foundations.

After Foundation Establishment, it’s not limited to practicing Dharma Seals of the Dao Foundation attribute; seals of other attributes can also be cultivated, only that Dao Foundation aids in seals of the same attribute, like fish in the water.

Dao Foundation is merely the groundwork; what to nurture depends on the cultivator’s choice.

There are many who practice Sword Seal, not all possessing Golden Rainbow Dao Foundation, but also Thunder, Fire Spirit, Water Attribute Dao Foundations as Sword Cultivators.

These types of Dao Foundation attributes offer peculiar effects to the Sword Technique, they are not unchangeable.

Gu Yuan showcases multiple Dharma Seals externally, leading others to merely regard him as supremely perceptive, capable of mastering many techniques without suspecting his possession of three Dao Foundations.

It’s not about fear; it’s about the lack of necessity.

Eighteen sword lights are sufficient to traverse this realm.

But at this moment, clearly not.

"Clatter clatter clatter!"

Water light surged, like turbulent waves crashing empty, allowing no demons near before pushing them away with endless water vapor.

The water seemed imbued with the unending strength of the Flood Dragon.

"Boom!"

"Boom!"

But now, the massive rumbling was clearly visible, with the entire island seeming to shake.

"This is..."

Startled, Gu Yuan looked up, and he saw a hundred-yard tall, gigantic Profound Turtle, resembling a towering mountain, stepping forward.

Though yet to reach the Great Demon Realm, its aura was as massive as the ocean, with Demonic Power proliferating, shrouding the sky, rolling like the sea, far surpassing the usual late stage of Earth Demon.

Eyes pitch-black, indifferent as ice, massive mouth filled with ghastly teeth, exuding an aura of menace.
