"It seems being strong is also a weakness! I've been there human, this world is vast than you know it. With time you will come to realize that there is more to this world than meets the eye. Now not to bore you. Zeta-Zone shift!! Abyssal Calamity!" Beelzebub said as the world instantly fell silent while wearing darkness enveloped him and Sagara.
In a blink of an eye,the whole scene changed from a normal jungle to a pitch black abyss that had night as black as skies if he'll, it had rivers of blood and mountains of bones. There was an erring silence on this realm and only the voice of Beelzebub could be heard, her formed had longed change from Damian to a devil, She had two long pitch black horns that stretched over her head, with a etheral like body that was adorned with several purple patterns. Her tail flowed freely in the air as it reached over 2 meters.
She held her hand high revealing her sharp arsenal of claws, that reflected death to any who stared at it.
"In this place I can draw out 20 percent of my power, your power pales in the fiendish strength I revail in you can dance with the devil in!" Belzebulv said with a wild grin as a towering moonsized purple blackish ball of energy formed ontop of both of them.
"Pathetic display of power, even though I've been weakened by half, your current form is nothing more than child's play!" Sagara said as he stretch his had causing a blue light barely the size of a basketball to form in his hand
Despite the size difference Beelzebub could tell that the power ether surpassed her own attack or was on the same level with hers.
The smile of arrogance never left Sagara face as he shot his energy blast at Beelzebub causing both of their attacks to collided resulting in an explosion comparable to a nuclear bomb. Both sagara and Beelzebub were pushed back a little as the wage of the recoil was not to be trifled with.
"Not bad human! With your power handling normal Ajumas should be a piece of cake! Even so we devil's are far superior! The most Noble race if all, with the lowest of us comparable to the strongest of humans! Allow me to emphasize on what strength is!" Beelzebub said as she dashed towards Sagara with speed comparable to light.
Her fingers was coated with a redish purple energy which made Sagara's smile shifted a bit. His body was pierced like bilutter as her hand dug through his stomach. "Damn!, U had relied on my technique bit who would have thought that you had learnt neutralization energy, which is neither positive or negative!" Sagara said as he teleported from where he was, of course as he expected his wounds refused to heal, Zeta energy existed in many forms but the only form humanity could use or even comprehend was negative, as that was what the Zenexian orb reflected. in fact that is the only form seen on Earth.
Sagara had developed what he called positive Zeta energy where he had multipleid the negative energy with another negative energy. The product was amazing, it's power could be called the square if zeta energy, it's efficiency and power was already amazing but then he felt he could now add the positive energy with enough negative energy to produce something new, ads as suspected he was right.
What he got was neither something positive or negative, It was neutral, it didn't posses tremendous power like positive energy or the purity of negative energy. At feirst he thought it was useless buy only when he understood the true essence of that energy did he finally knew it's potential. With that energy even someone with a common grade regalia could defeat legendary grade.
This energy form neutralize every other form of energy, it could be used to counter the attcaks if Regalias or anything at all, that was how powerful it was and seeing he was injured with it he knew there was no chance of him healing without proper concentration.
"Why wouldn't I be able to use neutral zeta energy, infact I was the one who created it! I was the only person capable tof even using it in the whole world when I was alive." Beelzebub said in a prideful smile. "You created it! Impressive but you could say I perfected it!" Sagara said as the same neutral zeta energy exploded from inside Beelzebub causing her to fall on her knees.
"What! Wh..what happened?" Beelzebub said as she could feel her consciousness slowly fading. "You would come to find out later! I'm afraid this fight has already attracted too many power House of humanity! They would be hear any minute from now!" Sagara said as he smiled at Beelzebub who had confusion written all over her face. "So you mean you could tell what is going on in the outside world from within my zone! Hahaha! It seems the generations of human after my death had long gotten stronger! I hope the same could be said for the devils.... you have enlightened me! Next time we meet you would undeniably loose to me!" Beelzebub said with a smile of recognition.
"I doubt that!" Sagara said as he watched her body slowly changed form to Damian While the zone slowly disappeared. Sagara walked over to Damian with a smile of satisfaction but that smile caused the blood he had been holding in to roll down his lips.
"It seems I can't be comfortable with my own strength, but I had longed reached the limit of power this world would allow but thanks to the changes of the Zenexian orb I can finally keep on rising..." Sagara looked at the Moon which now reflected powerful Ray's if zeta energy.
"It seems common grade regalia would soon disappear from this world and more people would start to awaken higher class regalia, probably a regalia higher than legendary grade! What a pity for people like me!" Sagara said as he took two steps with Damian in his shoulder before disappearing completely. it was at that same moment that somebody appeared on that same spot.
"It seems that what ever it is I just missed it! That enerfyysignatyred didn't come from any of the power House, infact those two energies I felt is far stronger than any of us."
