World's Strongest Martial Warrior

Yet, as the Indestructible Devil Emperor's attack bore down, Peter Parker's gaze remained steady, his face betraying no hint of panic.    

In the very next moment, the Heaven-Sealing Map materialized above Peter Parker's head. Under his command, it began to turn its pages.    

With each page flipped, an ancient and formidable beast sprang forth.    

In the blink of an eye, ten ancient beasts of diverse forms surged through the heavens and the earth, dispersing the destructive Great Dao that loomed over Peter Parker.    

"Heaven Sealing Map?" The Indestructible Demon Emperor's eyes narrowed at the sight. "It appears I've underestimated you. I never imagined you'd possess this Emperor Treasure."    

The Imperishable Demon Emperor was well-acquainted with the Heaven Sealing Map. In the ancient times, upon their arrival in the Immortal World and their battles with its various emperors, there was even a Devil Emperor who was subdued by the ancient beasts within the Heaven-Sealing Map.    

They had not anticipated that today, the youth clad in black would once again wield the Celestial Sealing Map.    

The Celestial Sealing Map, a legendary Emperor Treasure of the Immortal World, contained ten ancient ferocious beasts. Each beast's combat prowess was more formidable than even the mightiest Immortal Kings.    

The collective might of these ten ancient beasts was sufficient to confront an Immortal Emperor directly!    

At this juncture, Peter Parker had unleashed the full might of the Heavenly Sealing Map.    

"Just as one would expect from the legendary Heavenly Sealing Map, capable of standing toe-to-toe with an Immortal Emperor!" Below, Zi Qiong Immortal King and the others watched the awe-inspiring clash in the chaotic void, their eyes alight with excitement.    

The emergence of the ten supreme ancient beasts from the Heaven-Sealing Map effortlessly nullified the Undying Demon Emperor's cataclysmic assault.    

With the ten mighty ferocious beasts of the Heaven Sealing Map at their disposal, the Immortal World had a fighting chance against the Undying Demon Emperor.    

"Do you really think you can halt the advance of my Desolate Ancient Devil Palace just by wielding the Heaven Sealing Map?" taunted the Undying Demon Emperor, his chilling laugh echoing as he towered over the Black Dragon Devil King. His sinister voice permeated the Devil Suppressing Immortal Domain.    

"Black Dragon, take command of the Desolate Ancient Devil Palace and crush the immortal realms for me!" he ordered.    

The ten ancient beasts within the Heaven Sealing Map possessed overwhelming strength. Even the formidable Indestructible Demon Emperor might struggle to best them.    

Yet, the Immortal Kings of the Immortal World, led by Zi Qiong, had just sustained severe injuries at his hands. They were no match for the Black Dragon Devil King's might.    

As long as Zi Qiong and his cohort were out of the picture, even if the young upstart could use the Heavenseal Diagram to contain him, it wouldn't prevent the Desolate Ancient Devil Palace from conquering the Immortal Dimension!    

"At once, my lord!" The Black Dragon Devil King wasted no time upon receiving the Undying Demon Emperor's command. He swiftly mobilized the forces of the Ancient Devil Palace to confront Zi Qiong and his allies.    

"Understood," Mo Qingcheng acknowledged with a nod.    

Zi Qiong's expression shifted dramatically as he urgently beckoned his comrades to reform their defensive array.    

But their recent clash with the Undying Demon Emperor had left them gravely wounded. Even after reestablishing their formation, its power paled in comparison to that of the three cities. They stood little chance against the onslaught of devil experts marshaled by the Black Dragon Devil King.    

Soon enough, their defenses teetered on the brink of collapse under the relentless assault of the Black Dragon Demon King and his forces.    

Peter Parker's brow creased in concern as he observed the Violet Sky Immortal King and the others failing to repel the Desolate Ancient Devil Palace's attack.    

Without hesitation, he mentally commanded the ten colossal ancient beasts to launch an offensive against the Black Dragon Devil King and his minions.    

Each beast, as formidable as the Black Dragon Demon King himself, unleashed their unique powers, swiftly dispatching a Demon King apiece.    

In the span of a few moments, ten Demon Kings were vanquished by the ten mighty ancient beasts.    

Meanwhile, the Violet Sky Immortal King and his retreating forces managed to regain their footing.    

Witnessing Peter Parker dispatch the ten ancient beasts to aid Zi Qiong and the others left the Undying Devil Emperor in shock.    

He looked up at Peter Parker and said slowly, "Kid, you've caught me off guard. Do you really think you can take me on all by yourself?"    

Peter Parker gave the Indestructible Devil Emperor a cool glance. "Is there an issue?"    

"Kid, you're overestimating yourself. Even as a descendant of the Green Emperor, you can't possibly challenge me with your Immortal King Realm powers!"    

As the Imperishable Demon Emperor spoke, a torrent of devilish energy burst forth from him, engulfing the chaotic void. Overwhelming destructive forces shrouded the area, plunging the entire realm into darkness.    

"Brat, you're done for!"    

The Indestructible Demon Emperor's roar was followed by the demonic energy around him morphing into a sky full of demonic shadows.    

"Undying Devil Shadow!"    

At his command, thousands of devil shadows surged toward Peter Parker like a massive wave. The chaotic void was awash with innumerable dark torrents.    

Simultaneously, thousands of devils advanced. Each shadow possessed strength rivaling that of an Immortal King. Their fearsome devil Qi caused the chaotic void to fracture and break apart.    

Peter Parker stood serenely amidst the turmoil. As the horde of devils bore down on him, he swiftly brought his palms together in front of his chest to form a seal.    

In an instant, a black square seal, large enough to eclipse the sun of the Devil Suppressing Immortal Domain, confronted the onslaught of devil shadows.    

The Celestial Thearch Seal, the Celestial Soul Destruction Seal!    

With this move, the once thunderous devil shadow fell silent as if struck dumb. The black square seal acted like an insatiable black hole, devouring all the devil shadows in a blink.    

"This technique must be inherited from one of the most formidable Immortal Emperors in the Immortal World. I never expected you to possess the legacy of more than one Immortal Emperor!"    

Realizing his attack had been effortlessly countered, the Indestructible Devil Emperor's gaze intensified with murderous intent as he stared down Peter Parker.    

The young man before him was the chosen one of countless Immortal Emperors from the Immortal World, likely destined to confront the Ancient Devil Palace.    

At present, this youth had already acquired the strength to challenge him, even before ascending to the Immortal Emperor realm. Should he achieve that breakthrough, he feared he might no longer be his equal.    

With no hesitation, the Indestructible Devil Emperor extended his formidable Indestructible Devil Claw towards Peter Parker. As the massive claw neared, the space around Peter Parker didn't shatter; it seemed to melt, the very fabric of reality contracting as though drawing Peter inexorably closer to the looming claw.    

"Heavenly Emperor Seal, Mountain River Collapse. Heavenly Emperor Seal, Heavenly Emperor Silence!"    

Confronted with the Undying Demon Emperor's fearsome assault, Peter Parker unleashed the raw immortal energy within him, invoking the latter two seals of the Heavenly Emperor Seal.    

Boom! Boom!    

The two Heavenly Emperor Seals met the Immortal Demon Claw head-on, shattering the surrounding chaos. The impact sent Peter Parker hurtling backward, his form a blur amidst the tumultuous void.
