World's Strongest Martial Warrior

Suddenly, the silence of the ancient forest was shattered by an intense spatial ripple.    

In the next moment, a figure clad in black appeared in the sky above the mountainous woodland. It was Peter Parker, who had ventured into the ruins of the Immemorial Immortal King.    

Could this be the site of the Immemorial Immortal King's remains?    

Peter Parker descended gracefully, surveying his new surroundings with a curious glint in his eye.    

"Roar!"    

No sooner had Peter's feet touched the ground than a thunderous roar erupted from the dense forest behind him. Instantly, a massive black shadow burst forth, obliterating the surrounding flora with its sheer force.    

Peter's gaze sharpened as he observed the enormous tiger engulfed in black flames. The creature's aura was formidable, on par with a First Grade Heaven Immortal. Yet, what struck Peter most was the absence of any signs of life in the beast—it was unlike any ordinary creature, emanating a potent aura of death.    

Without hesitation, Peter extended his hand and with a flick of his finger, a sword-like energy sliced the giant tiger in two.    

The tiger's colossal form crashed to the ground with a thunderous boom.    

Peter's attention was drawn to a dark green pearl, egg-sized, nestled within the tiger's core. His eyes narrowed thoughtfully. Could this be the Dark Bead they were tasked with retrieving? Was this mighty tiger the fabled Ancient Underworld Immortal?    

Peter had assumed the Primeval Underworld Immortal would be a unique entity within the Primeval Immortal King Ruins. However, this encounter suggested something quite different from his expectations.    

With a slight flicker in his eyes, Peter secured the dark green bead from the tiger's remains and resumed his exploration of the forest.    

Shortly thereafter, Peter came across another formidable creature—a giant ape teetering on the edge of the Heavenly Immortal Realm, its aura nearly identical to that of the tiger he had just encountered.    

Peter Parker effortlessly dispatched the creature with a single blow. As expected, he discovered a dark green bead within the body of the giant ape.    

Witnessing this, Peter Parker felt almost certain that the giant tiger and ape before him were indeed the Ancient Underworld Immortals they were tasked with hunting. The term "Ancient Underworld Immortal" didn't actually refer to a specific living entity. If his hunch was right, there must have been a significant event at the Ancient Immortal King's burial site that transformed all creatures present into what were now called Ancient Underworld Immortals.    

"The Ancient Immortal King's remains are truly fascinating..." Peter Parker mused to himself. Without delay, he secured the Dark Bead from the ape's corpse and proceeded with his exploration.    

Subsequently, Peter Parker dispatched several Ancient Underworld Immortals in quick succession. These beings ranged from First to Fourth Grade Heaven Immortals, and Peter Parker eliminated them with ease.    

However, throughout his journey, Peter Parker had not come across any of the promising youths from the eighteen sub-palaces of the unnamed Immortal Palace. This suggested that the area surrounding the Immemorial Immortal King's remains was incredibly expansive.    

After some time spent investigating the Immemorial Immortal King's site, the sounds of combat finally reached his ears. Peter Parker's gaze lit up, and he instinctively moved toward the source of the commotion.    

Before long, a mysterious cave came into view. At its entrance, a young man clad in a blue robe was locked in battle with three ancient underworld immortals, each the size of a mouse with a single horn atop their heads. These adversaries were formidable; one had attained the Third Grade Heaven Immortal rank, while the other two were at the Second Grade Heaven Immortal level. Despite the blue-robed young man's impressive fighting prowess, he was clearly struggling against the trio's onslaught.    

"Friend, my name is Xu Ji from the eighth branch palace. Would you consider joining forces with me to take down these Primordial Underworld Immortals? We can split the spoils evenly," the youth proposed, having detected Peter Parker's approach. He eagerly sought Peter Parker's assistance.    

Despite being a First Grade Heaven Immortal prodigy from the eighth branch palace, his abilities were merely above average there. His cultivation at this level afforded him the combat prowess of, at best, a Third Grade Heaven Immortal. Now, overwhelmed by the onslaught of three Primordial Underworld Immortals, he was clearly at his breaking point.    

He wasn't certain of Peter Parker's full capabilities, but he knew that anyone who gained entry to this place was among the elite of the eighteen sub-palaces, suggesting they were no pushovers. If Peter Parker could take on even one Immemorial Dark Immortal, it would significantly ease his burden.    

Otherwise, his only option today would be to shatter his life-saving jade talisman and face premature expulsion from the secret realm. Having spent less than half a day here without the chance to fully explore, he was loath to accept such a defeat.    

After a moment's consideration, Peter Parker sprang into action. He launched a punch that tore through one of the Second Grade Heavenly Immortal Ancient Netherworld Immortals. Without missing a beat, he dispatched another Immemorial Underworld Immortal with a second devastating punch.    

Witnessing Peter Parker effortlessly eliminate two Second Grade Heavenly Immortal Ancient Netherworld Immortals with mere punches, the blue-robed young man inhaled sharply in astonishment. This young man's strength was evidently on par with his own, if not greater, given his ability to fell a Second Grade Heavenly Immortal Ancient Netherworld Immortal with a single strike.    

With the demise of the two Second Grade Heavenly Immortal Ancient Netherworld Immortals at Peter Parker's hands, the blue-robed young man felt the pressure lift. He launched an all-out assault on the remaining Third Grade Heavenly Immortal Ancient Netherworld Immortal, quickly gaining the upper hand.    

After a brief exchange of about ten moves, he executed the Greater Luo Immortal Art, decisively ending the battle with the Third Grade Heavenly Immortal Ancient Netherworld Immortal.    

Having vanquished the Immemorial Golden Immortal, the blue-robed young man turned to Peter Parker with a gesture of deep gratitude. "Xu Ji, I owe you my life, brother. Which branch palace do you hail from?" he inquired earnestly.    

Peter Parker spoke in a subdued tone, "I'm from the eighteenth branch palace, Peter Parker."    

Xu Ji's eyes widened in astonishment as he realized who stood before him. "Are you the one who made Yan Li back down with just one punch outside the Nameless Immortal City?"    

The news of a prodigious talent from the eighteenth sub-palace, who had compelled Yan Li of the third sub-palace to retreat with a mere punch, had already become the talk of the Nameless Immortal City. Xu Ji, of course, was well aware of the incident.    

It was something he had never anticipated.    

The most formidable individual he had come across in the mystic realm turned out to be the very same extraordinary genius from the eighteenth sub-palace!
