After a month of excavating and crafting, I finish my home. I made all kinds of rooms, even ones that I will potentially never use. I made a library, a smithy, a laboratory, an enchanting room, about 10 bedrooms, all kinds of living rooms and more. The total size of my base is probably as big as a large mansion. But it's all inside of a mountain, so it's even better.
Once I'm done creating the rooms. I start unloading things form my spacial storage. From books, to clothes, to even food and weapons. I have so many things inside there that I forgot more than half of it...
When I'm done with organising, another few days have passed. Now that my home is finally finished, I can start practising combat again.
Without wasting time, I start doing so.
My goal for now is to master all of my skills and arts, then start creating new ones.
For that, I leave my home and fly over to the sea, where I can not worry about destroying anything important. I erect a powerful barrier around myself and start practising.
I manifest the Excalibur Morgan and look at the sleek black and red sword in my hand. It's a thing of beauty, radiating with power.
This is the thing that has been wanting to awaken inside me since long ago. Yet I only managed to awaken it when I became a demon lord. I can't even see through to how much power this sword holds.
I make a casual slash with it, towards the sea. It's like the sword slices through the air seamlessly and creates vibrations in the air, at the same time.
It's such a confusing phenomenon that it makes you scratch your head and say: Power?
As I've only used this sword briefly, in a 4 day battle, I still have to work out it's characteristics. But it feels oddly familiar to me, like I've held it before...
However one thing is for certain. It is without doubt the most powerful sword I've ever seen. In fact I don't even know if it would be right to call this thing a sword...
....
....
....
As I spend my time alone, practising. Lifetimes pass by. The passage of time doesn't bother me though, so I quickly lose track of it.
Without me even knowing, over a thousand years passes by.
My training has been more than fruitful. I have now mastered all of my skills completely. I have also created countless mystic arts, for pretty much any situation I could think of.
This is all great. No, it's amazing. However I have discovered a problem. I have yet to actually put myself to the test. I have been fighting the creatures at sea to test my arts out, but the sea is the sea. I want to try fighting different creatures as well.
So now I have returned to my cave, that is looking like a proper mansion at this point. Living here for over a thousand years, I have made this place the home of homes.
While sitting in my throne like chair, I stretch my legs over the side and ponder about where to test myself.
Humans are out, as they are weak. There are some strong monsters out there, but I'm not keen on spending time on searching. I want to find a place where there's a lot of strong creatures in one place. If only I could find that red haired man again...
Finally I conclude the only sensible option. The demons.
There is a door on the continent I'm on. But it's not just a normal door, it's a special door. It's called the hellgate and it connects this world to the demon world.
From time to time I've seen some demons visit this plane, but I haven't interacted with them. They all chose not to interact with me as well, after they saw me execute one of my moves, so we never had the pleasure of getting aquainted.
But I think now is the time I visit them.
I stand up, fully nude. This is also something that changed. I ripped clothes apart so often, that I just didn't bother with them anymore.
Usually I just cover my private parts with darkness, or scales and done. It's much more practical, then changing clothes 100 times a day. Although when I'm in my house, I'm fully nude.
I stand up, fully nude and stare at the wall. This is one of the downsides of living underground. The lack of windows is apparent. I use my universal sense to scan most of the continent, quickly locating the hellgate.
Then I summon my usual outfit made of darkness and teleport straight next to the hellgate.
I stare at it in thought, as I have never used this kind of door. In my last life there was only aura and no magic. This door is purely magical, so I'll just have to figure it out.
I try the simplest approach and just walk through it. Unexpectedly it actually works. I feel the dimension changing all around me. Before I know it, I'm in hell.
This isn't such a dreary place at all. I was expecting a horrific scene of an apocalypse, but this is actually quite tame.
I start flying around. From time to time I encounter demons, but they're not worth my time.
After an hour of flying, I eventually encounter a decent demon. He flies at me top speed. Just before he can crash into me, I vanish. As he turns back to look at where I've gone, he notices his view tilted. It's like one of his eyes is lower then the other. The next second, his conciousness cuts out and his body vertically slides apart. It's clear that he was vertically bisected.
"Mhhn." I grunt in annoyance. That was too fast. I have to hold back next time...
I continue my flight and soon find another strong demon. This time it's a beatuiful woman with horns. She reminds me of a succubus.
Contrary to popular belief, she greets me not with erotic dreams, but with nuclear magic.
I move out of the way of the beam, then try out one of my many arts. Collapse.
She collapses into herself, as if a black hole was in her stomach. It's an incredibly gruesome sight and by her screams, an incredibly painful one as well. Within seconds, she has collapsed and been compressed into a fingertip sized marble.
"Umu." I nod with satisfaction. It's a very good art if it works that fast on targets that strong. That demon was around the archdemon level.
After that, I fly around the demon world and fight whomever strong I can find. I test out whatever I have in mind at that time and make sure to hold back, so that I don't just obliterate my dance partner at the start of the fight. Sometimes I still do though.
Years pass as I spend time in the demon world. I also spend time observing demons fight eachother. Some of them boast quite decent skill.
The demons do offer some resistance, but the arts I created are just too good. So far there has been only one demon that I considered taking seriously. He was the only one who could actually resist me and make me spend an effort.
....
Another day of mindless roaming, while dispatching a few insects from time to time.
However soon I come across something incredible. The demon I see is leagues apart from anything I've encountered here.
She's sitting on a pile of bones. Her eyes are locked on me, as she gazes at me with boredom. The woman has short blonde hair and blue eyes. She looks incredibly beautiful, with a slender frame.
I land straight in front of her throne, looking slightly up at her. Then I correct myself, by jumping up and standing on air, looking down at her.
This action manages to break the womans lazy expression and she furrows her brows.
"Who are you?" She asks with an even tone.
"My name is Artoria Pendragon, the corrupted true dragon. Who are you?" I say.
"I'm called Jaune, the yellow primordial." She answers with a smirk, while standing up and stepping in front of me.
"You seem rather strong for a demon, so don't die too fast." I smirk and tell her, then I punch her in the face.
She catches my fist with her hand and smirks. "Me? Die? Hahaha. I've yet to meet someone, other then those 2 bitches, who can say something so insulting to my face." She responds.
Then she uppercuts me and kicks me in the ribs. Her hits are accompanied by shockwaves and I go flying from the force of her kick.
"Nuclear cannon." She fires a large beam of nuclear magic at me, while I'm still in air.
I flip myself over in the air and grab my sword(Not excalibur). Then I gaze at the magic coming at me and get into a stance.
"Full counter." As it is about to hit me, I reflect the nuclear beam back to Jaune, with twice the strength it had.
*Boom* A rather large explosion happens when the magic hits.
However as I expected, Jaune is mostly unharmed. She looks at me and starts laughing. "Hahaha, that was wild! Where did you learn that?"
I relax myself a bit and answer her. "I created this technique myself."
"Hmm... In that case I'll let you see one of mine." She smiles and bends down. Then she disappeares and seems to slip through space, slashing through my body at speeds faster than light.
Even I didn't expect that. My body is cleanly bisected at the chest level. Even my heart is cut in half. I grab hold of my hips with my hands, so that my top half wouldn't slide off, while I wait for my regeneration to fix me. In only a second, I'm almost completely healed.
Jaune looks at me with an amused smirk. "You're already completely healed. You must have some insane regeneration huh."
"No, your attack was just so weak that you healed me, instead of damaging me." I answer with a provoking smirk.
"Heh." She smiles and throws beams of energy at me. I cast a barrier and similar to opening an umbrella in the rain, all the beams just harmlessly hit the barrier.
Then she appears behind me and kicks me in the head. I block it and go flying. She appeares beside me and throws a punch. I block it and go flying again.
She continues to rain down strikes on me. Each consecutive blow gets stronger and stronger. The shockwaves from her strikes absolutely demolish our surroundings. The objets close to us get even atomized.
Eventually she kicks me down to the molten ground and let's up. Just looking towards me from the sky.
Once the smoke clears, she sees my figure. I am dirty, but have no injuries. It's obvious that even though her attacks hit me, I didn't suffer damage.
"You are quite tough huh." She says with a big smile.
"You're not bad yourself." I respnd with a grin, exposing a row of sharp teeth.
She's only slightly weaker than me in my base form. I imagine if I would deactivate my darkness, her attacks would make more of an impact. My darkness gives me about a 40% boost in power, so in this state I have to make sure I don't accidentally erase her. But her being able to fight me is very impressive. Our fighting skills are at a similar level, with me being a bit better. I'd say she's top 3, after the red headed man and the white headed dragon...
"Hmm." She humms and touches her chin with a pondering expression. "You know, you've been releasing this murderous aura since the start, but I feel like you just want to try out your moves, instead of murder me. It's very confusing."
What she's saying is very true. This fight has been more of a martial arts demonstration, where we compare notes. Instead of a fight to the death.
"After traversing this plane for years, you're the first one to actually be able to put up a fight with me. I can't let the fun end so soon, you know." I respond.
She shows me a wide and cruel smile. "I know what you mean."
She conjures up some kind of high density orb with gravity magic and throws it down on me. I could instantly neutralize it with my ultimate skill, but instead I choose not to. I've decided not to use my ultimate skills aside from darkness.
I dodge the orb and counter. Starting my own rain of blows on her. We continue to fight for a long time. As our energy reserves are massive, we end up fighting for months.
We exchange all kinds of moves that we know of and even create some new ones mid battle.
Eventually we end up running low on energy, so we take a break.
