If their physical power were all, the King in Yellow would disdain the attack. What truly disturbed him were the Life Origin Essence's runes engraved in the swords.
Anyone thinking that Life Origin Essence lacked direct offensive battle power would be a fool.
The reason that the gaping wound on the King in Yellow's chest did not close, despite all his abilities, was the power of Life Origin Essence sealing any form of life or vitality in the area.
All wounds infected by the power of Life Origin Essence would find any form of healing impossible!
Just as the swords were about to pierce his head, the King in Yellow's eyes glowed as a special force that seemed to originate from a combination of Mind Force and eldritch aura emerged and created a dome, shielding him.
The King in Yellow had just handled one threat when a kick bathed in white lighting, and Astral Qi approached his head.
Not only was the kick extremely powerful, but also incredibly fast, as if it could bend space-time.
He could not use his tentacle arm due to the vibrational force keeping it occupied, but just as the kick was about to land, he used his own leg to block it, displaying an unbelievable level of martial skill.
Unlike his tentacle arm, the power of his leg was inferior. Still, instead of allowing the force to push him away, he rotated his body in the air and, without losing momentum, counterattacked.
That exchange between the trio occurred in less than a fraction of a second, and they immediately continued fighting.
While the King in Yellow had multiple wounds over his body, with the most meaningful one being the hole in his chest, the Neo-Demons also received several injuries.
The King in Yellow's attack not only carried immense strength but also infected the wounded area with an eldritch aura, corrupting everything it touched.
Any other Prima Universe's life form would have a tough time stopping the eldritch aura from expanding, but the Neo-Demons' unique Sacred Body of Laws seemed to be resilient against the alien power.
Of course, resilient and immune were very different, so both Zatiel and Ezequiel were careful.
Forty-five more minutes passed as the Neo-Demons, and the King in Yellow exchanged blows at the speed of light when finally Ezequiel's eyes glowed.
Zatiel did not even have to look or communicate with the Supreme Neo-Demon to know what happened. Their teamwork reached such a sublime level that their minds seemed capable of linking into a single train of thought.
The Neo-Demon Ancestor made his energy explode and attacked with ferocity, both with his bone sword and creations, forcing the King in Yellow to focus on him.
Ezequiel clenched his left hand with all his strength, making a spherical bubble carrying unique vibrational force appear before he attacked.
The King in Yellow again blocked the bone sword with his staff and used his own creations to protect himself as he countered the Supreme Neo-Demon's punch with his tentacle arm.
However, surprise appeared in his eyes when his tentacle arm collided with Ezequiel's fist. Instead of facing a massive shock power, what he felt was a vibrational force eliminating his atoms.
While the Law of Vibration may not sound as impressive as the Law of Life, the truth could not be more different.
Vibrations are a phenomenon capable of affecting everything on a physical level. They can travel through the air generating what we perceive as sound, speed up molecules producing heat, or reach such a high level that they can create earthquakes capable of shattering continents.
Using the ability of vibration to travel through the air, the Supreme Neo-Demon could make the Frost Monster Heart's leader feel an invisible force attacking her from every direction.
Of course, that was just a basic use of Vibration Origin Essence and would not work in a battle of this level.
Until now, Ezequiel only focused on gathering a tremendous amount of vibrational force in his left hand, making them explode when his fist connected, generating monstrous shock waves.
However, the power he just used and that surprised even the mighty King in Yellow was something in a completely different league.
Everything in the universe vibrates at a specific frequency, including objects, biological life forms, incorporeal creatures, energy, and even space-time.
By learning the vibrational frequency of your target, using Vibration Origin Essence, you could create a counter vibrational frequency that could annihilate him at an atomic level.
Learning a target's vibrational frequency was incredibly difficult, even for a battle genius like Ezequiel.
The Supreme Neo-Demon used every instant in which their bodies touched to perceive the King in Yellow's vibrational frequency.
It took him more than ten hours, but all the hard work paid off, and Ezequiel smiled as the counter vibrational frequency was about to annihilate the enemy he loathed so much.
The counter vibrational frequency already reached the King in Yellow's arm and would expand before completely erasing him almost instantly.
Unfortunately for Invictus, the keyword was almost.
It occurred in that time lapse between the counter frequency entering his arm and ultimately spreading over his whole body. At that moment, that was not even a fraction of a millisecond, in which no Rank 6 life form could ever manage to react; the King in Yellow proved his uniqueness.
"¡BOOM!"
Ezequiel's smile froze, and his eyes widened when he saw how the King in Yellow blew up his tentacle arm and stopped the counter vibrational frequency from reaching the rest of his body.
Before the Supreme Neo-Demon could react, a kick charged with immense strength and eldritch aura landed on his chin, shattering his jaw and sending him flying away.
As the King in Yellow connected that fierce attack, the flaming bone sword managed to generate a significant slash on his chest. The worst part was the Life Origin Essence that infected the wound.
The bone sword did not stop there as then attempted to pierce his right eye, but the King in Yellow managed to parry it just in time with his staff.
Zatiel and the King in Yellow stared at each other as they began to fight one on one.
