HDXD: Omni Harem System

RUMBLE!!...

The castle's training ground began to shake violently, with rocks and debris crashing down from above.

Yet, even as parts of the structure crumbled under the force of the shockwaves, they suddenly began to reconstruct themselves.

It was as if the damage meant nothing at all.

In the grand scheme, it was just a healable wound. In a way, that was exactly the case. Any harm sustained, simply regenerated right after, as the living construct constantly draws on his Monster Energy to restore itself, due to the deep, connection it shared with him.

Two people, equally powerful, equally destructive go against each other in raw physical combat.

Their first collided, creating shockwaves that could be felt throughout the entire castle as they train in the underground training ground.

But this battle was not one of equals, Adam was weaker as such the punch send him flying back, however using his wings, he flap to catch back his balance.

As he skid across the stone floors, his entire hands bleeding and swollen beyond measure.

Yet the grave wound was already starting to regenerate as Adam destroyed his body where it was damage and simply recreated it.

Not even a second later he went back to face the foe head on.

His foot stomped, launching him forward like a cannonball. His fist came in tight, elbow cocked, a clean Muay Thai cross.

Nyx however tilted her head just enough for the punch to graze her cheek, black hair fluttering as she pivoted.

Adam then twisted mid-motion seeing an opening, planting his heel and delivering a spinning tae kwon do hook kick, it cut through the air like a blade.

But Nyx was already beneath it.

WHOOSH...

Her body dipped low, legs sweeping the floor like a scythe. Adam jumped, flipping over her and landing with a skid. The floor cracked beneath his feet.

He grinned as the heat of battle existed him so, especially if it was with beautifully woman like Nyx.

Without a word, his style changed. Wing Chun, a recent martial art style he picked up from Minerva, a couple months back during their martial arts training, now his hands danced in rapid-fire strikes, targeting her throat, solar plexus, temple.

Tap-tap-tap.

Each strike hit nothing but wind.

Nyx's body blurred. One, two, three micro-steps. Her gaze never left him.

Adam launched his knee, using a Muay Thai clinch! He grabbed for her neck.

However Nyx was too fast for Adam properly react to, as she casually dodge his advance.

And then...

SLAM!

He was suddenly airborne, shoulder crashing into stone. Nyx had reversed the clinch with a perfect Judo shoulder throw, and before he could react.

BOOM!

Her heel drove toward his face. And I'm response to save his ass, Adam raised his arms in an X-block just in time, the floor beneath him exploding from the force of her kick.

Dust shot upward, as a massive crater was form just from the force alone.

"Hmmm not bad your getting better, but you are going to need to try harder than that if you want hit me babe."

"I-I am working on it...

Adam replied back, thinking of his next move as Nyx just place more force expanding the crater even more, and crushing Adam even more in the process.

Smoke and debris erupted upwards, casting the battlefield in a haze of dust.

But from that haze, Adam's figure emerged, his counter technique for a situation like this, switching martial art style again.

This time relying on Capoeira, his limbs whirled in rhythm, all grace and chaos alike, his feet flashing like blades. A spin, to get Nyx off him, a drop to better balance himself, and a rising axe kick to hit Nyx dead on.

But despite his speed, and strength behind his attack, Nyx caught it just as easily.

And Midair at that.

With only two fingers.

"...The hell?...

Adam shouted in shocked at what he was seeing, but before he could respond with another attack.

She twisted her body, after grabbing his leg, dragging Adam like a ragdoll.

As he spiraled, and moments after was slammed face-first into the ground, but caught himself in a handstand, flipped backward, and blasted forward with a Krav Maga lunge, elbow driving like a missile toward her heart.

The counter was beautiful, the sheer supernatural control Adam had over his body was insane he could counter himself from any attack with technique alone.

Nyx however did not move.

But as he approach, his momentum suddenly died, stopping him and his attack completely.

Eyes wide, Adam looked down. And realized her hand was already on his chest.

"Very nice babe, I really was really suprise by that counter."

Nyx said coolly, her eyes steady.

"Alas though...you're still fighting like a human would, that is the only reason why you can't reach me."

She said even calmer than before, calm, her presence weighing down the air.

"If you really want to grow, you need to stop copying and start creating your own style using the many martial style I have thought you as a blueprint. You've got potential, but you're still switching between styles you didn't shape yourself. I've trained in every martial art Earth had to offer. I know how to counter all of them. No matter how fast or how unique you adapt to counter me, it's still familiar to me."

Her hand hovered just inches from his chest, right below his heart.

Then, without warning...

BOOOOM!!!

A single, precise one-inch punch hit Adam square in the chest. The impact was instant. The air ripped as he flew backward, breaking the sound barrier.

He slammed into the wall, hard enough to leave a crater. Blood spilled from his mouth, a sharp, ragged gasp escaping as he slumped in the stone.

A clean hole had been punched through his chest.

It didn't kill him, but it felt like it could have.

Pain shot through his entire body, but he pushed through it. This wasn't the first time Nyx had beaten him within an inch of his life, only to heal him right after.

Even before he gained his newly evolved body, capable of self-healing by breaking down and rebuilding itself, he was nearly impossible to kill.

Wounds alone regardless of the severity of them wouldn't stop him. Not even decapitation could finish the job.

In simple terms, he was built to endure.

And endure he did, as the hole in his chest quickly started to heal closing up perfectly almost as if it wasn't even there.

Still it hurts like a mother fucker, but even so, Adam was more than use to pain this point in his life.

"Ugh… I've been stabbed, burned alive, ripped clean in half, many time before, in many different ways, by many different things, hell, one guy even turned my brain into a damn heat bomb and blew my fucking head off."

Adam groaned, dragging himself upright, one hand pressed to his chest.

"But your punch? That simple little thing? To this day, hurts way worse than all of that. Seriously, woman, what the hell do you put in those hits to make it hurt the way it does?!"

Adam asked, his face still sweating from the phantom pain of the hit.

And the wound it created, despite it being fully healed now.

Seeing this Nyx just chuckled, as she approaches him, then reached out and pulled him to his feet.

Right after, he looked him over, her expression unreadable behind her veil.

"It'' not about what I put in, rather it's what I don't waste in technique."

She said casually, then continued by fully going into details behind her attacks.

"You see, I target key nerves. Acupuncture mixed with clean martial technique, controlled force, and just the right amount of vibration. My attack can spread pain rapidly and constantly right through your body. So it nothing really complex rather it just combining two martial style together to create an intended result you see."

Adam blinked suprise by Nyx method of fighting, as he said.

"So you basically weaponize acupuncture?"

She smirked faintly.

"Something like that, it simple in explanation, but complex in practical. But with this style of hitting, one well-placed punch from me can knock out a blue whale regardless of where I hit, it doesn't even need to be hard. Too much pain in the right spot, and your nervous system just... shuts down."

Adam stared at her for a beat. Then let out a shaky laugh.

"I see, I will definitely remember that, it could definitely decided a battle before it even starts if done correct for sure."

Said Adam.

"That is true, but the stronger and more durable an enemy is, the more harder it is going to be to just casually pull it off."

"Hmmm, hahahaha... Still it seems like a convient martial technique, you got to teach me how to properly execute it, still, I that is enough for today don't you think?"

"If you say so babe, still, I noticed you were a little distracted today with your training when I was teaching you how wrap miasma around your bones, and nerve to increase flexibility and density of your strikes, is something bothering you or something?"

Nyx asked the question casually, and Adam looked at her, smiling softly as he replied.

"How sweet."

He said out a loud, then continued.

"Well… to be honest Nyx, yeah something is bothering me. You see, I think I'm getting close to my second evolution. But I've been having trouble actually reaching it."

"Hmmm, Stage Two, huh."

Nyx mused, tilting her head slightly.

"Takes me back to my younger days. I was around eleven when I hit my second."

She paused, then added with a shrug.

"Still, it shouldn't be that hard to trigger it now. Didn't you kill an A-rank monster a couple months back?"

Adam nodded slowly.

"Yeah… why do you ask?"

"Well....

Nyx said with a faint smirk.

"If you still have the body around, why not just eat it? I am sure the body is still in good condition. If you do that, it'll definitely trigger your evolution."

Adam's eyes narrowed thoughtfully, then he began to spoke.

"Minerva did say something along those lines… So, if I eat monsters, I can trigger a natural evolution?"

He asked, and Nyx responded without hesitation.

"Yeah. It is one of the most common ways to evolve. For Metahumans, stronger monsters contain more potent Monster Energy. That energy forces your own to react, stimulates it violently, pushes it to adapt you see. And when your Monster Energy evolves if it was able to overcome it, your body follows suit."
