Hero of Darkness

Even Kahn was bamboozled at this point because even his unparalleled and probably one of the most sure-shot killing moves aka the Dimensional Cut that could cut anything in 3 kilometers range with a single swing at this point… failed to cut off Cthulhu's head.

"What the hell happened here? Is its unique ability that much overpowered?" asked Kahn himself in a befuddled voice. 

The system had already informed him about Cthulhu's unique ability. If even an entire arm was cut down, it could reattach and recover instantly without any ramifications. 

But the neck region was always the weakest part and an unrivaled attack skill like Dimensional Cut should've been enough to cut off Cthulhu's head. 

[Boy… your attack did cut its neck. But the cells regenerated and healed it so fast that you couldn't even see it happening.] informed Rathnaar in Kahn's mind. 

"Katon Surasshu!" 

BANG!! 

While Kahn was taken aback because of this incident, Omega in Twilight Armor quickly used Kojin while harnessing the dragonfire to make a powerful katana slash strike. 

This was one of his newly created skills that killed the legendary rank Venialkarto monster in a single swing. 

RAWWRRR!! 

The Cthulhu roared in pain for the first time as he was hit with the attack and although the massive 100 meter long katana didn't penetrate its defense… the Dragonfire still spread across its entire body. 

But even after getting burned alive by the strongest fire on the planet… 

Its instant regeneration ability was healing it continuously and it completely recovered in just 15 seconds. 

"Truly worthy of being a descendant of the Primordial Titans." said Kahn with an incredulous and hateful expression, almost jealous at this point. 

With their current attack skills, restrictions placed by domains on the physical stats such as attack, defense, agility and health… even the Elder Hydra would've died easily because of this unified onslaught. 

But the Cthulhu was so strong, being impervious to most of their attacks. Even the strongest attack skills Kahn, Omega and Rudra had were just barely enough to temporarily injure it. 

This regeneration speed was even 5 times faster than the Elder Hydra. 

GROWL!! 

This time, the Cthulhu revealed a murderous aura, much denser than before because it was thoroughly infuriated from the previous attack. 

And to counter this onslaught, the Cthulhu just waved its hands and its eyes glowed even brighter. 

Swooom! 

Swoom!! 

Soon, hundreds of massive pillars of whirling water rose and thousands of blades made of high-pressured water came to be. 

All of these creations rotated in a circular motion and encircled the massive titan descendant, creating an impenetrable wall of protection. 

The nearby 3 kilometers of area was now full of this typhoon-like barrier and all three of them were forced to retreat. 

Because these blades were more than capable of injuring their bodies even if they could make only shallow cuts. However, if thousands of those blades attacked together… even someone like Rudra, who had the strongest defense in their crew, would be turned into minced meat after some time. 

Blackwall was holding one front but in the end, the enemy was still 15 times stronger than him and there was very little he could do. 

Even Cthulhu's command of water was simply too powerful. 

Just the water blades made of incomprehensible pressure were big and sharp enough to cut through Adamantine and Orichalcum, two of the hardest metals in this world easily. 

If they weren't using all these domains and pendragon formation to repress the floor boss, all of them would already be dead. 

This creature was a descendant of the primordial titans. Those beings existed even before Dragons and Godbeasts in the world. 

Even the Legendary rank Mountain Titan they fought in Verlassen was something they barely managed to kill because of luck and Dimensional Cut divine ability. 

"Looks like all our methods are useless. 

Even Dimensional Cut won't kill it because it'd be able to regenerate instantly even if I cut the core." spoke Kahn in dejection. 

The regeneration abilities and impenetrable defenses made it a nigh-invincible enemy. And a prolonged battle would only benefit Cthulhu because of the unending supply of water from the sea. 

In the end, it'd be them who ran out of world energy while the boss simply stood quietly without even having a scratch on its body. 

"Even destroying its core won't do the job." said Kahn. 

This was the 2nd unique ability of Cthulhu. 

Even if they destroyed its heart, cut the core or even butchered its entire body… the mythical rank boss would still be able to pull back all of its destroyed body parts and regenerate on the spot. 

In simple words… Cthulhu was unkillable with their current skills and abilities. 

"I can use a skill to get out of this situation. But losing the core would be way too big a loss. I'm pretty sure the Elder Hydra would've given me a lot of useful abilities if I wasn't forced to destroy its core. 

So this time… let's kill and harvest the body properly." Kahn declared his intention. 

Just then, Rathnaar decided to speak. 

[Kid… you have no choice but to use that.] 

To his voice, Kahn replied with a somber expression. 

"Yeah… but I still can't fully control it and it's really taxing on mind and burdens my soul greatly." he iterated. 

Because Kahn remembered the only weakness of Cthulhu that system told him about. 

​ Sigh! 

Kahn sighed in helplessness but the following moment, his expression turned full of fortitude and sovereignty. 

Crack! 

Crack! 

Suddenly, a dimensional void crack appeared beside Kahn. 

Flick! 

Flickr! 

A massive orb emanating black, white, red and yellow light came out from the True Dimension. 

Even the Cthulhu was instantly alarmed and faltered in its steps. 

ROAR!! 

The mythical rank boss roared in anger as it felt the threat from this 5 meter tall object. 

"Tell me. Do you bleed?" 

He spoke in an overbearing voice and suddenly and the next second… 

BOOM!! 

A horrifying and insurmountable aura arose from this object, terrifying the boss for the first time since the battle began. 

"You will."

Kahn declared majestically and the orb started raging wildly as intense and scalding flames arose from it. 

Since even the Dragonfire wasn't being helpful against Cthulhu, a big comparable to God in their eyes.

Kahn had his own Godkiller. 

At this moment, he decided to utilize the strongest weapon he currently possessed. 

The Divine Weapon… Amaterasu.
