The clash between the two titanic beings had begun in earnest. Their blows sent shockwaves that shook the very foundation of Ryuken's divine domain. Yet, it was clear Kahn had no intention of allowing the battle to drag on. With his newfound mastery from the 4th Enlightenment in Space Law, he prepared to unleash a devastating counter. "Abyssal Lightning!" Kahn roared, his voice a thunderclap that reverberated through the distorted air. BOOM! A blinding beam, 200 meters wide, burst forth from Kahn's outstretched blade. Malevolent darkness and rampaging lightning coiled together in perfect harmony, forming a destructive force that was as beautiful as it was terrifying. The beam erupted with the speed and force of a hypersonic bullet fired from a celestial cannon. Reality itself quivered. Rupture! The fabric of Ryuken's domain splintered under the onslaught. The beam carved a path of annihilation, stretching an unfathomable 25 kilometers in a straight line. Valleys, mountains, and even the ethereal constructs of the domain disintegrated into nothingness, their existence erased by the sheer destructive might of Kahn's strike. And then… the point of impact. Thud! Thud! The battlefield trembled as Ryuken's gargantuan form collapsed into two grotesque chunks of flesh. His Domain of Sacred Divinity, a fusion of his divine spirits, was torn asunder. The upper half of his form, now reduced to two pairs of arms, fell to one side. The lower half with legs still intact, crumbled on the other. The chest and torso, the very core of his massive, divine body… were obliterated, leaving nothing but void where his heart of power had once been. Silence! For a moment, there was silence. The oppressive aura that had once filled the domain dissipated, replaced by an eerie emptiness. Dust and debris floated aimlessly in the ruined realm, the aftermath of Kahn's decisive blow evident in every fractured piece of the battlefield. The onlookers, Ryuken's companions included, were frozen in shock. Although none of them could see what was happening in the two overlapping and intermingled domains, the battlefield where the Sacred Divinity and the Apostle of War were fighting… just the sheer tremors and shockwaves they felt from 50 kilometers away were more than enough to raise their worries. "This can't be…" one of the spirits whispered, their voice trembling with disbelief. The others, even the most malevolent among them, were momentarily silenced. The sheer devastation wrought by Kahn's Abyssal Lightning attack had left them with no words. Kahn stood tall, his Apostleo of War form emanating a predatory aura that seemed to grow stronger as he surveyed the battlefield. His crimson eyes flickered with a mixture of satisfaction and unwavering determination as he lowered Muramasa, the darkness blade crackling faintly with residual lightning. "Tch! Was that all?" asked Kahn in a grim voice, the disdain visible in his eyes. He genuinely expected more from this fight, but a single powerful move of his had eviscerated the Sacred Divinity, leading to his disappointment. "Now then, let's wait till he reverts to his original form," Kahn's voice echoed across the devastated battlefield, his Apostle form radiating an aura of calm dominance that belied the chaotic aftermath. Squirm! Squirm! A grotesque movement rippled through the severed remains of Ryuken's Sacred Divinity. Thousands of writhing tentacles sprouted from the dismembered chunks of his massive body, snaking and latching onto the opposing halves. Despite its colossal size, the regeneration was unnervingly rapid, knitting flesh and form together in a matter of seconds. In just 10 seconds, the Sacred Divinity stood whole once more, its crimson, horned figure fully restored as though Kahn's catastrophic strike had never happened. "Bullshit! Isn't this instant regeneration?" Kahn exclaimed, his disbelief evident. As someone who possessed the Mythical-Rank Cthulhu's Instant Regeneration skill, he was intimately familiar with such feats. But to witness it on this scale was another matter entirely. Thud! The ground shuddered as the Sacred Divinity planted its massive foot, the force reverberating across the ruined battlefield. "Urmmmgghhh!" groaned the enormous entity, its voice a guttural snarl. "This wretched bastard! He dares kill us?!" it bellowed, a seething rage radiating from its towering form. The amalgam of divine spirits spoke with a collective voice that seemed to tear through the fabric of the air itself. "We may not be originally from this world," the Sacred Divinity sneered, its tone dripping with disdain, "but that doesn't mean our unique powers are rendered useless. We cannot be permanently killed by the multiple elements of reality or the laws we possess." As if to prove its point, all eight arms regenerated to their peak condition, each hand gripping the otherworldly katanas infused with incomprehensible elemental energy. "So, you're invulnerable to space law and elements like lightning, light, water, darkness, wood, fire, and blood magic?" Kahn asked, his voice steady but his posture shifting into a defensive stance. He had already started analyzing the situation, his mind working at a breakneck pace to decipher this newfound revelation. If there was one thing Kahn excelled at, it was adapting under pressure. "You're quite smart," the Sacred Divinity sneered. Its massive frame seemed to exude smugness, even behind its mask. "How does it make you feel? Knowing that no matter what you try, you will never be able to truly kill us?" Kahn's crimson eyes narrowed as the entity gloated shamelessly, its contemptuous tone further fueling his resolve. The revelation was troubling, to say the least. His most potent attacks; darkness, lightning, and the devastating powers granted by Space Law... were now ineffective. The Sacred Divinity's regeneration and invulnerability to elemental forces posed a monumental challenge. Obviously, Kahn also couldn't use the Divine Weapon Amaterasu here either. That would be akin to willingly blowing up his cover since Ryuken was most likely listening from inside this titanic form, just that he wasn't in control anymore. It would be plain stupidity especially given how he still hadn't achieved his primary goals and the fact that he and Ryuken were on odd terms at the very moment. [Even pulling him in the True Dimension won't work. Just as many of his powers won't work on me, mine will yield the same result. We will be at an endless stalemate at this point. Also, my Apostle of War mode has a time limit. It's better to finish things quickly than leave it to uncertainty.] thought Kahn as he analyzed the situation and tried to come up with a new strategy to overturn the situation in his favor. And suddenly… Kahn's lips curled into a faint, predatory smirk. "Invincible, huh?" he murmured, his voice low but brimming with quiet defiance. It wasn't the first time he had faced an opponent who claimed to be unkillable. It wouldn't be the last. [There's always a way.] he thought, gripping Muramasa tighter as he readied himself for what would undoubtedly be his toughest fight yet. "Let's put that claim to the test." "Awaken!" iterated the Apostle of War in a domineering tone. Swoom! Swoom! Suddenly, everything on the ground turned pitch-black as the entire Dimensional Domain and the Domain of Sacred Divinity turned into a realm of eternal abyss. RAWWRRR!! GRRR!! One after another, thousands and then millions of monstrous creatures arose from the ground, like shadows emerging from the cold and lifeless darkness. Kahn's crimson eyes glinted with unyielding determination as he extended his arms, summoning his monster army in a flash of dark, shimmering energy. A vast horde of millions of grotesque and powerful creatures, ranging from Elite to Lord Rank materialized across the sky and the battlefield, each emanating a deadly aura. But to the shock of everyone watching, he didn't command them to attack Ryuken. Instead, he raised Muramasa with a chilling smirk. [I don't like using this cheat code.] Kahn muttered to himself, his voice tinged with exasperation. [It's not cost-effective and burns a big hole in my wallet. Now I'll have to spend billions of SSS-Rank monster cores to bring these guys back later.] The creatures roared and screeched, seemingly unaware of their impending fate. Kahn's grip on his sword tightened as he prepared to unleash an ability he had avoided using ever since arriving in Vantrea. The True Demon bloodline effect! For the first time in his long and arduous journey, Kahn was ready to activate this terrifying power. The Chaos Demon bloodline effect was an ability that could transform mass slaughter into an overwhelming, exponential power boost and raising his Strength stats by 5 times. However, its activation came at a steep price: Kahn had to personally kill thousands of enemies in rapid succession to achieve its peak potential. Previously, only Jugram, Kahn's subordinate, had utilized this effect during battles. Jugram's fighting style made it ideal; his overwhelming destructive power allowed him to annihilate hordes of enemies with ease. For Kahn, however, none of his past battles had required such tactics. His enemies had been singular, powerful foes, not legions of adversaries. But now, in this dire situation against Ryuken's Sacred Divinity, where conventional methods proved ineffective… Kahn knew he needed an unconventional solution. Slash! With a single sweep of Muramasa, Kahn decapitated millions of his summoned creatures by using the Dimensional Cut. Their bodies crumbled into glowing fragments of mana and blood essence, feeding into him as streams of dark red energy coiled around his massive form. 𝒻𝑟ℯℯ𝑤𝑒𝑏𝑛𝘰𝓋𝑒𝓁.𝒸𝑜𝘮 His Apostle of War's wolf head glowed even brighter, and his draconic wings expanded as if they were absorbing the very essence of destruction and chaos. Each swing of his blade felled thousands of more of his monsters, and each death amplified the horrifying aura surrounding him. As the horde dwindled, Kahn's power surged. His once-overwhelming aura grew even more potent, evolving into a storm of pure chaos energy. A crimson-red light enveloped him, pulsating with an otherworldly resonance. The overwhelming force shattered the remaining fragments of Ryuken's domain within a 10-kilometer radius. Finally, as the last of his monsters fell, Kahn straightened, his form now glowing with a malevolent brilliance. He clenched his fists, feeling the raw strength coursing through him. For the first time, Kahn's aura matched that of a Peak 7th-Stage Saint, a level of power that could shake the heavens and earth alike. And finally, Kahn's entire body made of pure Darkness had turned into Blood-red, changing his aura of lifeless darkness into merciless bloodlust. His voice boomed across the battlefield, commanding attention as it resonated with the weight of his newfound strength. "Behold the true power of Chaos!"
