There were two reasons that I wanted for the Parasite to go berserk. One was related to his increased vulnerability to physical and magical attacks. The other one was his lack of coordination to attack.

While it did increase his physical capabilities to twice as much as before, also making him much more receptive to any soul or mental attacks. I guess I wouldn't need to worry about it because..

"Anti-Magic Circle," I muttered before unleashing the real potential of the magic circle.

-SSSCCREAEATTTHHHH!!!!!!

"Wh.. at.. Is..." Mark spoke, getting weaker, along with the others too. Including the Parasite, of course, who was screeching out as loud as possible. I saw him doing everything he can to prevent losing his power, but he was miserably failing to do so.

Not caring about what others were feeling or doing, I proceed to the next spell,

"Reverse Magic Engineering: Sorption of Mana."

All the mana which was entering into the circle started flowing inside me.. I observed the whole process and also took notice of people in my surroundings.

"This is really something to be honest," a feminine voice spoke from behind me and I turned around to see Aelia, looking at her power increasing with a flabbergasted expression.

"Don't be surprised, just now," I muttered before letting the blood flow freely through my body to the circle and vice versa. Another function of the circle was to amplify the mana I had.

And then I saw my powers increasing to its max potential it could reach without going beyond. If I had to guess now, then I was barely SSS-Level and since Aelia's powers scaled along with me, she too must be at SSS-Level.

"We have 60 seconds," I muttered before looking at Aelia, who dashed towards that Parasite. Normally, Aelia would have killed the Parasite in an instant, but with the Parasite's regeneration capability in his berserk form along with his high tenacity and resistance to pain, he too was in SSS-Grade, albeit barely.

'Also Aelia, a blood user, is a bad match against him,' I thought before looking at Eliza and Bernette who were lying there. Since I was this powerful now..

I rushed towards Eliza and touched her, immediately curing her with the level of powers I had. My deal with Cristine is complete, now to complete the other task. I thought before vanishing from there and reaching Cristine, who was literally shocked and nervous at the same time.

I dumped the two girls on her, and she looked at them relaxed a little, before turning at me, but I had already reached back to where I should belong.

-BOOOOM!!!!!

I punched the Parasite as hard as I could, making him reach the other side, but before he could escape the circle, I activated another defence mechanism of the circle using my power and created a wall preventing him from getting out of the circle.

"Take everyone away," I said as I looked at Aelia and she nodded before using her area wide blood manipulation magic to get everyone out of the circle towards Cristine on one of the towers.

The others were too weak to do anything against this as they 'left' the battle before looking at me and that Parasite. Now.. it was me vs it.

"About time I get real, don't you think?" I spoke as I saw him standing slowly and regenerating to its prime health before glaring at me.

"Blood Sacrifice: True Reaper," I muttered before blood started pouring out of my skin and my eyes were turning darker and darker. The blood creeped deep within the sword I was holding, increasing its size and slightly changing its shape.

Even my hair, which was black, had turned half red. I looked at that parasite with a creepy smile as I spoke,

"Welcome to hell!"

And then I dashed towards him as fast as I could

-Swish

-Slash!

-SCREEEETTTTCCCHHHH!!!

I saw him screeching with my one attack before proceeding towards me with a ferocious look and once again,I dodge him easily as I cut him again

-SCREEETTCH!!

historical

Making him scream all over again. I knew it wouldn't be enough.. no, it will be far from the damage it will take to kill him.. so I dashed again, slashed again, turned around, dashed again, slashed again.

The process repeated 10s of times in the first seconds, 100s of times after 10 seconds, 1000 slashed by the end where I slashed each and every part of his body into a thousand separate pieces.

After I was done with that, I saw him clearly and completely, all his parts, his eggs with which he could reproduce. His mana core with which he drew his evolutionary power. His dark black thread, specific to them, gave them their genetic properties.

"Shadow Style: One Hundred Slashes of Eternity," I muttered in a low yet cold breath before sending dark energy slashes towards him.. from the front, from behind, front the sides, above, everywhere.

Those hundred slashes came instantly, went instantly, cutting the last bits of him. I saw him making his last screech as I huffed, hoping it would end at this. My eyes observed it for the rest of the time and when he fell down and didn't make a single screech even after the next few seconds, I finally concluded that he was dead.

My eyes then turned to Mark Leeway and the others, who were looking at me with a deep gaze motionless. Reeve and the others who didn't make any contribution to the battle at all were left wondering what was their role in all this.. which was, to be honest, to fill the magic circle with their power. Oliver's addition was a really nice touch to it.

'Though, I doubt they would have accepted this, if I had told them about it from the start,' I thought before my consciousness faded slowly. I saw Aelia, slowly evaporating as well as she smiled at me while muttering something along the lines of 'Good job!'
