Clouds started to turn dark and around the demon's sorrounding trees, grass and any living thing started to wither and die.
*RUMBLE*
The ground was now quaking and cracking, rocks floating mid-air and winds blowing heavily at every direction.
Feeling the dark energy getting more strong in the sorroundings and flowing towards the demon who was inside a cocoon, Nezu was now getting really serious, gripping Hakai no Ken tightly in his left hand.
Then inside the cocoon, a pair of horns emerge slowly followed up by arms that was bulging with muscles and was covered by strange tattoos same with his other body parts, he was much more bigger and radiating strong bloodlust. His wings and tails are now gone, if his horns were gone too, someone won't know he is a demon and mistake him to be human.
"You're really strong for a puny human too make me push to my limits and help me breakthrough with my strength." even the demons voice was change and was now so deep and cold that make people with weak willpower to shiver to death.
Hearing what the demons explanation, Nezu was pissed, 'Fuck isn't it always the protagonist that always breakthrough when fighting against tough opponents?' Nezu feel that he was cheated and his aura was flaring uncontrollably.
The demon thought that Nezu realize his grave situation and was preparing to fight him to the death.
"Hmph, my powers now is way much more powerful than before, its like comparing heaven and earth and your futile efforts is useless." the demon said proudly while clenching his fist forward, and with a punching stance, he slowly punch towards Nezu's direction.
Looking at the demon that suddenly move strangely, Nezu furrow his brows in puzzelment, but at that moment he suddenly sense danger coming towards him but was too late to dodge so with no other choice, he coat his arms with Elemental Power and make a defensive X stance forward to take the danger head on.
*BOOM*
Nezu was lifted to the ground and was push back until he hit a tree but it didn't stop him and took him a few more trees to stop his thrashing. Standing while still in his X stance, Nezu cursed at the sudden powerup of the shit,'Fuck my arms almost got disabled if I didn't use my Destruction Element at the last moment' rubbing his arms that was slightly numb, Nezu stare at the demon who is still proudly floating in mid-air.
"Oh? You survive that? You're really strong for a human, well did you like my gift? Its my aprreciation towards your help in my breackthrough, Hahahaha" the demon laugh maniacally and his previous arrogant self was back.
"I must say you're one of strongest human i've face before but still not enough if you cant make your Element to materialize in its spirit form" the demon said while looking at Nezu's confuse expression.
"Hahaha don't tell me you don't even know what Element Materialization is? Oh yeah I remember you're a hero and my king said that heroes are not from this world so you're like just a piece of shit hahahahaha" the demon continued to mock Nezu while flexing his bulging muscles.
Satisfied, the demon continue with a mocking tone, "It won't be interesting if you don't know the gap between our strength so I'll chat with you a little bit and enjoy your despair expression after, hahahaha" the demon become complacent and didn't quickly end Nezu and instead decide to play with him a bit. He has the strength of a Low Master Rank Elementalist now, what could a puny human do?
Nezu's still calm and was also not in a hurry and decided to listen what this demon has to say, 'I still didn't use my Destruction Element so I may still have a chance fighting this demon if I go all out' Nezu began to plan his next actions while taking the chance to rest.
"I'll tell you about the Beginner rank first, those trash can only control their Elemental power to strengthen their bodies and was only stronger than an average human and if you advance in stages in your rank the effect became more powerful. And the Intermediate Rank scrubs can control their Elemental power to strengthen other things beside their bodies, for example an elementalist who uses weapons, they can strengthen it to become more sharpier and durable, and for the advance rank elementalist, if you reach this rank you'll be considered a powerhouse because people who are in this rank can control their elemental power perfectly base on the stages their rank at and can attack using Elemental Power and release Auras to pressure people whose rank was lower than them. and if they have elemental types their strength is much more powerful than a normal Elementalist with same rank. For example you, for you to control your elemental power at your will and even shot attacks made out of Elemental power is amazing and already at peak stages of advance rank." the demon said his lengthy info dump while mocking those weaklings in the Beginner and Intermediate rank.
"And now the Master rank, almost all the people's limit is the Advance rank because materializing your elemental power is too fucking difficult if they didn't have luck or opportunity, that's why I'll have to thank you for this help hahahaha" said the demon while laughing loudly.
"Now I'm kinda bored talking about this shit, do you know the gap in our strength now? Come on let me see your face full of despair." Seeing that Nezu was still calm, the demon got irritated and fully unleash his dark element.
"Hmhp, let see how far can you keep that calm shit face of yours" the demon stretch his hands and suddenly the darkness element in the sorrounding gather over the demon's stretch hand, then a large black broadsword materialize.
"Hahaha look at my Darkness Element Spirit form, this power of darkness is filling me with ecstasy."
Nezu was unfazed and current thinking about something, 'So I'm at Advance Rank Elementalist right now huh and base on that demon's explanation my perfect control over my Elemental Power put me at Peak Advance Rank, so to breakthrough this rank is to make my Destruction Element materialize and have its spirit form.' Nezu was deep in thought and planning how to fight this demon now. 'I guess I can only try to breakthrough to have a chance at this fight.'
Nezu prepare for the toughest fight he has after arriving in this world.
