World's Strongest Martial Warrior

At the entrance of the palace, a formidable assembly of human-shaped Ancient Underworld Immortals had convened, numbering over ten. The least powerful among them ranked as a seventh-grade Heaven Immortal, with two even boasting the might of ninth-grade Heaven Immortal Immemorial Underworld Immortals.    

The group was led by a commanding Immemorial Underworld Immortal clad in black armor, exuding an aura that surpassed even that of a ninth-grade Heaven Immortal Immemorial Underworld Immortal. It was suspected that he was at least on the cusp of becoming a Golden Immortal.    

"Brother Jiang Chen, with so many Primordial Underworld Immortals gathered outside the ancient palace, what's our next move?" Xu Ji, visibly shaken by the formidable presence of the immortals, turned to his companion for guidance.    

Each Ancient Underworld Immortal present was a force to be reckoned with, with even the weakest among them possessing devastating power.    

"Stay alert. I'll handle these Immemorial Underworld Immortals," Peter Parker said, his eyes betraying a hint of resolve. He addressed Xu Ji before confidently advancing toward the palace.    

Their mission was twofold: to hunt Ancient Underworld Immortals for Underworld Pearls and to explore the Ancient Immortal Palace for hidden fortunes. Having stumbled upon this palace, Peter Parker was determined not to walk away without investigating.    

As Peter Parker neared the palace, the group of immortals outside became aware of his approach. All but the black-armored leader let out ferocious roars and charged toward him in unison.    

With an impassive countenance, Peter Parker unleashed the full force of his fourth-grade Heaven Immortal aura. From the Skyfrost Immortal Sword, a dense and lethal sword light burst forth.    

Immortal Killing Sword Art!    

Without a moment's hesitation, he executed three techniques of the Immortal Killing Sword Art simultaneously. Three resplendent sword energies, capable of vanquishing immortals and deities alike, sliced through three thousand meters of space, illuminating the once gloomy sky. They hurtled toward the onrushing Ancient Netherworld Immortals, destined for a cataclysmic clash.    

In a mere moment, the battlefield was strewn with the bodies of Ancient Netherhell Immortals—most were either dead or severely wounded. Only two or three of the mightiest among them were sent reeling through the air in a pitiful state.    

Peter Parker wasted no time on the surviving Ancient Underworld Immortals. With another swift motion of the Green Emperor Sword, he dispatched the remaining three with lethal precision.    

"Hiss... Is this the extent of Brother Jiang Chen's power?" Xu Ji's gaze was vacant as he watched Peter Parker cut down more than a dozen Immemorial Underworld Immortals with the ease of slicing through vegetables. It took him quite some time to shake off his astonishment.    

Even though Peter Parker had previously demonstrated formidable strength against the Duanmu brothers from the Ninth Sub Palace and had even countered Duanmu Yang's ace move, the spectacle before him was far more staggering.    

With the prowess of a Fourth Grade Heavenly Immortal, Peter Parker was dispatching Ninth Grade Heavenly Immortal Ancient Underworld Immortals as if he were merely butchering chickens or dogs. Was such an exaggeration even necessary?    

Xu Ji couldn't shake the feeling that even Luo Shock Scale, heralded as one of the top ten prodigies of the Northern Chill Immortal Domain, might fall short against Peter Parker.    

"Die..." The last black-armored ancient abyssal immortal, witnessing the swift demise of over ten of his comrades at Peter Parker's hands, hissed the word with venom. He then brandished a saber adorned with a ghostly visage and lunged at Peter Parker.    

Boom! The saber, imbued with the essence of death, materialized above Peter Parker, shattering the space into a vast, gaping spatial black hole that seemed poised to consume him.    

"One Seal Immortal Soul Extinguishing!" Peter Parker bellowed. He summoned the formidable Heavenly Emperor's Individual Immortal Soul Extinguishing Seal, which transformed into the palm of an ancient immortal and demon, crashing into the black hole.    

The two colossal forces met in a silent clash, the air pregnant with their unspeakable power.    

The black-armored ancient abyssal immortal's saber was obliterated by the sheer might of Peter Parker's palm strike.    

"Heavenly... Heavenly Emperor Seal?" A flicker of realization pierced the confusion in the eyes of the black-armored Immemorial Underworld Immortal as he murmured in disbelief.    

Peter Parker's heart raced with shock upon hearing the black-armored Ancient Underworld Immortal's mutterings. His gaze fixed on the figure before him. "Who are you? How do you know of the Heavenly Emperor Seal?"    

This black-armored Ancient Underworld Immortal was markedly different from the others Peter Parker and his companions had come across. There was a glimmer of awareness in his demeanor that was unmistakable. Yet, Peter Parker had never anticipated that this individual could identify the Heavenly Emperor Seal in an instant.    

The Heavenly Emperor Seal, crafted by a legendary Immortal Emperor who had once dominated an entire era, was now a mystery to most in the Immortal World. Who was this Black Armored Underworld Immortal, and how could he possess such intimate knowledge of the Heavenly Emperor Seal?    

Could it be possible that this being had ties to the renowned Celestial Thearch from the Primordial Era?    

Without a word, the black-armored Ancient Underworld Immortal cast a fleeting glance at Peter Parker, then turned and vanished into the valley's depths, saber in hand.    

Peter Parker watched the retreating figure, his eyes alight with curiosity. It was not only the recognition of the Heavenly Emperor Seal but also the fact that the black-armored Immemorial Underworld Immortal had chosen to withdraw after its revelation. Peter was convinced that this individual must be connected to the Heavenly Emperor in some way.    

His mind raced with possibilities. Perhaps these ancient sect ruins, and even the broader ancient immortal king ruins, were linked to the legendary Heavenly Emperor.    

"Brother Jiang Chen, what just happened? Why did the Black-Armored Underworld Immortal suddenly retreat?" Xu Ji approached, his expression one of bewilderment, as he watched the figure disappear.    

"I'm not sure," Peter Parker admitted, shaking his head. He didn't want to dwell on it. His attention was drawn to the ancient palace before them. Taking a deep breath, he suggested, "Let's go inside and explore."    

The ancient palace, having stood the test of time, was devoid of any protective forces. With no resistance, Peter Parker and his companions stepped into the ancient structure unimpeded.    

The interior of the ancient palace was modest in size, spanning only a few hundred meters in radius. A single glance was enough to take in the entirety of its contents.    

At the heart of the palace sat a golden-armored figure in a cross-legged position, long since deceased, the number of years lost to time.    

Scattered before this armored sentinel were several items. Among them lay an ancient sword, its craftsmanship appearing no less remarkable than Peter Parker's own Skyfrost Immortal Sword. It was, without a doubt, a Great Luo Immortal Sword.    

Beside the impressive blade, a collection of ancient scrolls lay blanketed in dust, clearly the legacy of the golden-armored man's cultivation techniques.    

Peter Parker spared only a brief look at these scrolls before his attention drifted away from the inheritance of cultivation techniques. His interest settled on a fragmented letter, its contents a narrative of past events.
