Some Transformed Realm Demons, who heard the commotion yet haven't arrived, fled in panic. Those who couldn't escape in time were even revealed in their original forms by the aftermath.

In the void, the dragon's roar shook the heavens, its fierce assaults continuous and unceasing.

In just a few breaths, Jiang Shu exchanged dozens of blows with the Black Dragon Demon Lord!

The originally brilliant lightning on the dragon's body diminished by nearly half, causing its aura to show signs of violent instability.

Under the absolute power of the Black Dragon Demon Lord, even though Jiang Shu had fully activated the power of Great Dao and his Heavenly Dragon True Body, he was still inevitably at a disadvantage.

Especially, the Black Dragon Demon Lord's terrifying dragon claws, capable of tearing through heavens and earth, each swing exerted immense pressure on Jiang Shu. Even if he vigorously defended, he felt his blood boil within from the counterforce.

"Hahaha! You little bastard, let's see what you can do now!"

"Just obediently face your death!!"

Seeing that Jiang Shu's Heavenly Dragon True Body was retreating amidst his fierce attacks, showing signs of failure to withstand, the Black Dragon Demon Lord laughed aloud.

Simultaneously, even more astonishing power condensed from the Black Dragon's claws, crashing directly towards Jiang Shu's head!

Detecting the destructive waves emanating from the Black Dragon's claws, a solemn look flashed in Jiang Shu's pale golden dragon eyes.

He fiercely bit his lip, his gaze revealing a rare fierceness.

The dormant spiritual power in his sea of consciousness surged out instantly, injected into the surrounding Five Elements Dao and Thunder Dao.

In an instant, multiple solidified paths emitted a humming vibration, and a constant stream of Dao Origin poured forth, rushing towards the Heavenly Dragon True Body.

With the addition of this Power of Dao Origin, the dragon might emanating from the Heavenly Dragon True Body surged once more.

The next instant, two formidable True Dragons launched world-ending assaults, suddenly clashing!

"Boom!"

Vast Primordial Power erupted completely like thousands of volcanoes silent for ages suddenly awaken, causing earth-shattering echoes.

Demonic black light and thunderous brilliance surged instantly like waves sweeping horizontally, covering the entire sky.

The Black Dragon's might and the Heavenly Dragon's pressure each occupied half of the sky, constantly invading the other. Demonic power and Thunder Power rose and fell, causing the void to groan under unbearable strain, cracking spaces repeatedly splitting and mending in cycles.

At this moment, in the eyes of both dragons reflected the other's image, filled with boundless killing intent.

The battle has reached this point, and they spared no effort, mobilizing all their power. Especially the Black Dragon Demon Lord, whose dense demonic power erupted continuously, his facial expressions becoming increasingly fierce and cruel.

Finally, after standing firm for dozens of breaths, the lightning surrounding the Heavenly Dragon emitted faint shattering sounds.

Upon witnessing this, the Black Dragon Demon Lord became extremely excited.

This kid is finally on the verge of collapse.

Honestly, after exchanging blows with Jiang Shu, even the Black Dragon Demon Lord found himself somewhat fearful of Jiang Shu.

Jiang Shu is only at the Vientiane Realm Early Stage yet mastered endless powers of the Great Dao, even briefly contending with him, a renowned Demon Monarch!

If today Jiang Shu was also at the Vientiane Realm Middle Stage, wouldn't he only have the choice to flee?!

This kid's talent is too monstrous, no matter what, he must completely eliminate this threat today!

Thinking of this, a bloodthirsty look appeared on the Black Dragon Demon Lord's cheeks, and a pair of dark dragon horns atop his head suddenly unleashed an extremely fierce wave of demonic power, blasting towards Jiang Shu's Heavenly Dragon True Body.

At this moment, Jiang Shu was already struggling to fend off the Black Dragon Demon Lord's assaults, daring not to divide his attention carelessly. Suddenly seeing the mighty demonic power unleashed from the dragon horns, his expression finally shifted slightly!

Not good!

That fierce demonic power was unbelievably fast, breaking through the layers of lightning barriers in front of the Heavenly Dragon True Body in an instant, arriving before Jiang Shu.

In this life-and-death crisis, determination filled Jiang Shu's eyes, pushing his Primordial Power and the power of the Great Dao to the limit, even causing his meridians to ache. He forcefully split a strand of divine thought, delving into the palm-sized ancient mirror hidden at his chest.

This item was a treasure bestowed upon Jiang Shu when he returned from the Ancient Demon Sect Relics, upon being promoted as Deputy Sect Master of True Martial Sect by the Supreme Sect Leader!

Refined with a Devouring Sky Hou Demon Core, possessing Peak of Vientiane Realm cultivation, into a Dao Artifact, the Swallowing Sky Mirror!

Aside from the life-saving talisman from the Supreme Sect Leader and the 'Immortal' order from Wenxian Palace, this mirror was Jiang Shu's most formidable defense!

Buzz! Buzz!

Activated by his soul power, the antiquated black mirror quivered, displaying numerous misty spirit lights, rising into the air; an extremely eerie aura suddenly spread.

The mirror reflected darkness, devoid of light, as if even rays would be swallowed completely within, exhausted away!

The name Swallowing Heaven indeed is extraordinary!

As the Swallowing Sky Mirror was unleashed, the Black Dragon Demon Lord's fierce demonic assault arrived!

Demonic power shattered the void, roaring forth, containing destructive waves, mostly blasting into the Swallowing Sky Mirror!

However, as Jiang Shu hurriedly activated the mirror, even using its full power couldn't intercept all that demonic power, leaving residual power cutting past the black mirror surface, ferociously striking his manifested Heavenly Dragon Body!

Boom! Boom!

Demonic black light reached the heavens and earth, fully unleashing its power; the Heavenly Dragon True Body shook violently and, impacted by the massive force, flew straight back.

The demonic power constantly dispersed along the way, causing invisible Heaven and Earth Primordial Qi to emit sharp, explosive sounds, shattering the space!

However, the Black Dragon Demon Lord upon his strike didn't reveal the anticipated joy but showed a trace of a human-like astonished expression, the huge scarlet dragon eyes flashed strangely.

"The aura from the ancient mirror seemed like Ancient Strange Beasts' energy, the Devouring Sky Hou?"

The unique fluctuation sensed from the mirror shocked the Black Dragon Demon Lord.

Beasts like the Devouring Sky Hou, even in their current Demon Race status, equate to the Black Dragon Clan, or even more prestigious due to rarity.

And within their Demon Domain, the Devouring Sky Hou Clan hasn't appeared for a millennium, already extinct.

"Humph! Damn it! How did this kid acquire so many opportunities and treasures!"

Seeing Jiang Shu constantly activating rare Divine Skills and Dao Artifacts, the Black Dragon Demon Lord felt exceedingly envious.

Before the failure of the last Ancient Demon Sect Relics mission, he held a significant status within the Demon Race, accumulating for thousands of years, yet didn't possess a single Dao Artifact of genuine value.

Whereas Jiang Shu, having just entered the Vientiane Realm, owns so many treasures, and the Black Dragon Demon Lord undoubtedly felt immensely unbalanced!

"Humph! No matter how many divine skills and Dao Artifacts you possess, today you'll not escape my palm!"

"Once I slay you, those treasures will be mine!"

In his dragon eyes, a greedy gleam appeared, the Black Dragon Demon Lord grinned, sharp dragon teeth glimmering with chilling light in the dim sky, eerie and terrifying.

Meanwhile, not far ahead.

The Heavenly Dragon True Body was blasted back over ten thousand feet by the fierce demonic power, barely stabilizing, its brilliance fluctuating as the rugged and terrifying dragon body rapidly shrank, ultimately reverting to Jiang Shu's human form.

"Cough, cough."

Light coughs revealed trickles of blood at his lips; Jiang Shu raised his eyes towards the black dragon hovering in the sky, madness surged in his eyes!
