When my white flames were about to overpower him, he activated his final ability [Inferno Domain] and our surrounding became more hot, my senses alerted me to distance myself from morris and I did so but morris grabbed me, his body pulsing with lava from within, his wound, I could see visible black and red lines of lava, which was enough to melt me in an instance, if touched him and therefore I had to build distance between us as soon as possible.
Not caring about consequences I accumulated the white flames in my mouth and bit the neck of morris in doing so my own mouth was burned and started to melt, my skull and teeth became visible but ignoring the pain I tore a huge chunk of meat from morris neck and morris released me from his grip throwing away from him and crashed on the ground.
My attack just now had not weakened him much because his [Inferno domain] was still active. I had heard about his domain skill but sensing it firsthand, I could say that the rumors were understated.
Our surrounding has become complete red, if he uses his ability in the capital he could melt the whole city in hours.
The heat which was radiating from him would get hotter more near I get him and there was only one way to defeat him and that was to overpower his [inferno Domain], which would be tough in my current condition but I had my last trump card prepared for this kind of situation.
Transforming into my humanoid form my face healed but the burning marks still remained. I retrieved both my swords [Punisher] and [Aurora] and held them in both hands.
I simultaneously activated the two active ability of [Punisher] sword, first was [Overload] which would strengthen me temporarily and second ability which I hasn't used till now and wasn't intending to [Soul sacrifice].
Unlike how the white flame used my life force and shortened my life span, which was I had enough to sacrifice, the second ability [Soul sacrifice] used my own soul to empower myself. Using soul based techniques would permanently weaken the user's souls, which can only be recovered when the dragon evolves into next stage.
In my case the next stage of evolution was primordial dragon, which would take me millions of years to reach and till then I would be cripple with a weak soul or evolving into next stage would be as good as dream for me due to using [Soul sacrifice] but no matter the cost I have to win this fight.
Not only for me but also for all the other retainers, Lord Alex and the future of dragon realm, otherwise our plan would be exposed to the king even before we have entered the 100th floor.
When I activated [Soul sacrifice] the feeling of pain vanished from my body and a cold sensation overtook me, my wounds began to heal rapidly and my body started to get filled with power I had never felt before.
No matter how much I enjoyed this feeling, I have to end this fight as soon as I can otherwise my whole soul will be consumed by this sword.
[Sacred Flame Domain]
The white flames left my body at my command overtaking the area around me extinguishing the black flames and slowly chipping away the [Inferno domain] of morris, from now on, it wouldn't be fight between us but a game of tug of war, A battle for supremacy to see whose domain prevails but I wasn't not going to play his games with his rules.
I attacked him with [Void slash] with the sword [Aurora] which I was holding in my other hand but this time the effect of [Void slash] was different because it was powerful than before, a clear white flash of light passed in the direction slashing the ground cutting through the black flames and passed through the huge body of morris.
He let out a painful cry and his domain weakened while my domain advanced. With a sense of satisfaction I also felt a pain in my heart which indicted that I didn't have much time and without wasting a millisecond, I once again used [Void slash] this time aiming for his heart. He tried to avoid the attack but so did I changed its direction landing a perfect hit on his chest.
I tried to muster the strength to fly but I couldn't, imbuing as much strength as I could I jumped into the air reaching the height of 250 meter ready to use [Void slash] once again but morris fired his [dragon breath] in my direction with all his might.
Ignoring his [Dragon breath] I covered myself with white flames and cut through his [Dragon breath]. If one would look from outside the dome it would seem like a white comet cutting through a black lesser.
With all the limiters removed from my body, I intensified the white flames and after reaching near enough, I used one last [Void slash] but not from sword [Aurora] but my father's sword [Punisher] penetrating his heart at point blank range.
The sword was not able to bear the burden of [Void slash] and broke after penetrating the heart of morris. The huge amount of mana reserved inside the sword from the time when I activated [Soul sacrifice] till now burst outside destroying morris from inside, his eyes lost its color slowly while lips showed that old disgusting grin.
"Repent in hell and wait for your king there, he will join you soon." I said as I fell near the body of morris.
The ability [Soul sacrifice] ended when the sword got destroyed and all the strength I had felt left me, paralyzing my body.
As I fell to the ground I saw from my half open eyes that in the huge dragon claw of morris were 2 Gem which were continuously blinking with light, so he intend to drag me with him.
My life started to play before my eyes, my younger self training with my family, the betrayal of morris and my whole life driven by revenge after that.
When I finally had the chance to repay the favor to Lord Alex by participating in the raid, you bastard stole that opportunity from me.
At least I got the chance to kill you. I turned toward the other end of transparent dome from where Lord Alex was spectating our fight and I smiled at him saying thank you but only my lips moved and no voice came out of my mouth.
As I looked at him my consciousness slipped and a cold sensation enveloped my whole body, I think this is how it feels to die.
