He had already sensed that the Power of Great Dao emanating from the Annihilation Seal was exceedingly dense, far beyond his capacity to withstand!

In his panic, he could only clumsily inject Primordial Power into the thousand-foot tall Demon Tower that hovered behind him, causing it to emit a dense and almost sticky black mist, enveloping his entire body and forming layers of solid and heavy defense!

In the next moment, the Annihilation Seal shattered the void, descending with a boom!

"Bang!"

A series of dull explosive sounds erupted, the incredibly violent Power of Great Dao was unleashed without reservation, pouring out continuously, causing the black mist to tremble violently, with the mist dissipating and scattering away.

It only lasted less than three breaths; this mist, which could withstand the full strike of a Daoist Monarch of the Vientiane Realm Early Stage, had become as thin as paper, and Daoist Monarch Black Soul, hidden within, was completely exposed to the onslaught of the Annihilation Seal.

"No!"

His eyes widened, his gaze almost tearing apart, as Daoist Monarch Black Soul watched the Annihilation Seal shatter all the defenses above his head, with the Power of Great Dao pressing down like a raging sea, completely submerging him.

Piercing screams echoed through the clouds, shocking the Demon Sect and Demon Race spectators, sweat instantly dripping from their foreheads, and even a few True Monarchs with lesser cultivation shivered slightly because of it.

Lord Heavenly Phoenix shuddered even more, his eyes widening to the extreme, a trace of unobstructed shock surging in his gaze!

Even among the people of the True Martial Sect below in Great Tomb Canyon, they gazed upwards in disbelief, their eyes almost frozen, their mouths agape, and even Lu Chong was no exception!

They were not surprised that Jiang Shu could advance to the Vientiane Realm and achieve Daoist Monarch, but nobody expected that after his breakthrough, his battle prowess would become so terrifying!

Although the life and death of Daoist Monarch Black Soul, struck by the Annihilation Seal, was unknown, judging by his earlier wretched response and the final scream, it was not hard to deduce that his confrontation with Jiang Shu's Divine Skill would likely end disastrously!

Such an extraordinarily domineering display of battle power, one that Lu Chong and others had never seen before!

Under the shocked or uneasy gazes from all directions, the Annihilation Seal erupted in a thunderous vibration, the black mist completely dissipating; that elderly figure struggled violently, but all efforts were in vain.

Until the power of the Annihilation Seal fully erupted!

"Bang..."

Under the crushing pressure, Daoist Monarch Black Soul's body was smashed to pieces, like a ripe tomato crushed by an irresistible force, suddenly bursting apart!

And his cold spiritual power fluctuations disappeared entirely alongside it!

Under the Annihilation Seal, both body and soul were obliterated!

High in the air, severed limbs and blood rained down, swept by gusts of wind, dispersing the thin blood mist, which drifted faintly toward the horizon.

After the Five Emperors Annihilation Seal, the entire scene fell into a deathly silence.

The gazes turned into stupor, and everyone forgot to breathe.

"Hiss..."

Only after several breaths did someone emit a sound of nervously sucking in the cold air, waking everyone present abruptly, and intense waves flared up in their eyes!

This was a legitimate Daoist Monarch of the Vientiane Realm!

Yet before their eyes, he was utterly obliterated by Jiang Shu with a mere Divine Skill, not even his Divine Soul could escape!

This also meant that Daoist Monarch Black Soul couldn't leave any True Spirit to reincarnate and resurrect in the future; he was completely fallen in these Ancient Demon Sect Relics!

In the distance, Lord Heavenly Phoenix looked at Jiang Shu in horror, his androgynous face suddenly turning pale as paper, filled with a deep sense of dread.

Only at this point did he finally realize, the Dao Heart, which he thought invincible after advancing to the Demon Monarch Realm, had collapsed again.

How was it possible, how could this Jiang Taixuan, in the Nirvana Realm, possess unrivaled battle prowess within the same realm?

And after advancing to the Vientiane Realm, still remain so terrifying!

He had spent several days with Daoist Monarch Black Soul and had a rough understanding of the latter's capabilities.

Since Jiang Shu could kill Black Soul with one strike, it indicated that Daoist Monarch Taixuan's current strength far exceeded Heavenly Phoenix himself and the Daoist Monarch Dayuan Lu Chong below.

He might even surpass Daoist Monarch Qingtian, Zong Yue, significantly, almost rivalling the current foremost figure in the Vientiane Realm in the Demon Sect Relics, Daoist Monarch of Great Disaster, Qiu Taoguang.

With such transcendent strength, Lord Heavenly Phoenix recognized that he was certainly no match for him.

Furthermore, below in Great Tomb Canyon, there was Daoist Monarch Dayuan Lu Chong, who still retained some combat power.

If he lingered here, death would be the only path awaiting him.

"No, I must escape quickly and report this to Daoist Monarch Qiu from the Demon Sect!"

"Jiang Taixuan has grown his wings, I am definitely not his opponent, it seems only Daoist Monarch Qiu can personally suppress him!"

There was no time for excessive hesitation; Lord Heavenly Phoenix's eyes flickered constantly, immediately making a decision.

Subsequently, a brilliant light surged up in his gloomy eyes, his body brimming with demonic power instantly boiled, soaring into the sky.

"Screech!"

A resounding phoenix cry suddenly echoed through the clouds, in the center of the boiling demonic power, a brilliant light burst forth from Lord Heavenly Phoenix's slender body.

The light grew with the wind, rapidly expanding, a pair of golden-feathered wings unfurled swiftly from within.

Then, as the glow receded, a Heavenly Phoenix, entirely gilded and extremely majestic, appeared in a shockingly imposing manner before everyone's eyes!

Each golden feather radiated immense demonic power, with the Heavenly Phoenix raising its head and singing clearly, its wings vibrating, revealing a noble and oppressive grandeur akin to imperial lineage.

Under the overwhelming imposition brought by Jiang Shu, Lord Heavenly Phoenix astonishingly manifested his true Heavenly Phoenix form directly.

In his large, cold, dark phoenix eyes, golden light circulated, and glancing once at Jiang Shu standing proudly in the void, Lord Heavenly Phoenix dared not hesitate any further, rapidly flapping his clouds-piercing wings, intending to flee swiftly from this place.

"Trying to escape?"

Seeing Lord Heavenly Phoenix soaring upwards, about to escape, Jiang Shu raised his sword-like eyebrows, then let out a heavy, cold snort:

"Too late."

Before the words finished, he stepped forward, causing a trembling and oscillating phenomenon in the Heavenly Space Dao above his head, mysterious waves surged forth from within, spreading and intersecting the sky!

In an instant, under this Space Power, all the Primordial Power in heaven and earth violently erupted, the void twisted and transformed, directly solidifying into numerous Space Prisons!

And the Heavenly Phoenix, yet to flee far, was trapped in one of these space prisons, no matter how frantically he flapped his wings, he couldn't break through the space barrier to escape to safety!

He could only watch helplessly as Jiang Shu stood in the nearby void, his uplifted right hand exuding a startling Great Dao fluctuation, slashing down fiercely!

At this moment, a sense of dread surged within Lord Heavenly Phoenix, an indescribable threat of death suddenly soaring into his mind, causing all of his golden feathers to stand on end, showing intense fear in his golden phoenix eyes.

Buzz!

As Jiang Shu's palm descended, the heavens and earth suddenly trembled, the Power Dao roared out, mighty Primordial Power surged, instantly condensing into a giant axe of deep black, exuding an endless breath of obliteration, as if traversing countless epochs from ancient times.

Panwu Heaven Opening Axe.

The unmatched axe light manifested, towering and earth-linking, suddenly blazing brightly.

Under the terrified, almost desperate gaze of the Heavenly Phoenix, it descended from the skies, slashing down with a roar.

Splurt!

A massive intact phoenix head, severed by the Heaven Opening Axe, gushing with hot blood spurting like fountains from the severed neck cavity!

Bang!

Lord Heavenly Phoenix's enormous head fell from the sky, heavily crashing to the ground, rolling a few times before coming to a halt.

The wide phoenix eyes reflected the tall and slender figure above, a brief flicker of resentment and unwillingness passing through them, before vanishing as the light in his eyes faded away.
