After dissecting Midget's body and cutting him down into pieces for later usage in Alchemy, I moved the limbs to a separate room and froze them all, except one arm, the right arm. After that, I took out several ingredients that were strong in demonic energy which I've left soaking in the vampiric blood of the three guinea pigs that had given up their lives for our research. When I took them out, they were emanating a large quantity of vampiric essence.

"These are… Horns? And also bones and animal claws… What sort of chimera arm are you trying to make, my lord?!" Asked Eleanora.

"I am merely maximizing results by making it as strong as I can before getting it into my body. I've already learned enough through the death of these three. I am quite confident that things will go as planned." I answered her, as I began to combine the pieces with the arm through [Synthesis] an Alchemy ability that merges components.

It seems to be possible to merge these components into the arm through this method. However, while I was in the middle of this process, something strange happened.

The arm, which was supposed to be dead by now as it was taken away from a corpse, began to move desperately everywhere, trying to escape from my grasp. The area where it had a wound suddenly shapeshifted, opening a grotesque mouth with several sharp teeth circling around it.

"GRUUOOHHH!"

"T-The arm is moving!"

Eleanora began to panic for some reason, but I remained calm, grabbing the arm and using stakes to get it stuck over the stone table.

"So you're alive already, huh?" I sighed. "Then can you eat these things willingly, or do you want me to tear you into pieces and reconstruct you?"

"G-Gruoh…"

The Arm as swiftly tamed, and began eating everything I gave to it, I decided to give it the Demon General's torso, his Demon Core, his blood, and several other materials from monsters, alongside the ones I had drenched in vampiric blood for several days.

"I-It ate everything…" Eleanora's eyes opened wide, as the arm began to emanate a powerful dark red aura. Enormous claws emerged from its former black nails, and it was growing a hard, steel-like set of scales over it, while the shoulder part had three sets of black spiraling horns.

"It's perfect!" I said with fascination.

"You're not really planning on getting that thing in your tiny and cute human child body, right?!" Eleanora asked. "The Demon Eye was the limit!"

"Eleanora! If you don't think widely, you'll never see through the big picture! I'll absorb these demonic powers, combine them with my vampiric powers, and create the ultimate strength to beat Lucifer! I am going to one day punch him in the face, this arm will do it!" I laughed manically.

"S-So you were just crafting the perfect face-punching face you could?!" Eleanora asked in disbelief.

"Huh? Why else would I do this?" I sighed. "Of course, I want its powers, but there's also a meaning to this hard work… Now, let's begin."

p I immediately cut my right arm without hesitation, as blood began pouring out of the wound. The cut was clean as I used Gluttony's sharp blade, it was rather hurtful to the point I gritted my teeth and began to sweat constantly, however, as it was an arm and not an eye, it wouldn't be as hard to put in my body.

"Now come here." I grabbed the arm with my left arm, as the creature looked at the open wound.

"GRUOOH!"

CRUNCH!

The monstrous beast began to devour my flesh and my bones, drinking all my blood, at the same time, I drank several of the potions I had crafted, recovering my health, and also fueling myself with demonic energy to feed the arm. It took me three whole hours to completely fuse with the harm, stitching it with Eleanor's Blood Threads and then merging my bones with the arm's bones. Ultimately, I feed the arm with my original arm as well so there wouldn't be any evidence left.

"I-It is a success…! Ugh… Hahh…"

I began to feel slightly dizzy, gasping for air. The Arm was still absorbing my energy despite having completely merged now. The energy it emanated had yet to merge with mine, and still seemed like an alien energy trying to infect my body.

"Now…!"

I quickly began infusing Blood Ki, Mana, and Demonic Energy into my Physique, making it react to the enormous and monstrous arm, the physique quickly began spreading Ki runes over the entire arm, taking over it.

After an hour of arduous work where I ended drinking all of the twenty-five potions I had made, things finally ended. I felt fatigued and, quite honestly, at death's door. Eleanora thankfully brought me a large amount of food I had stored, eating it all to restore all my energy and lost calories.

I spent the entire two next hours stuffing myself with as much food as possible. When I finally finished, the arm had calmed itself completely, and was no longer absorbing my energy, but sharing its own powers with my body.

And of course, the arm had slowly shapeshifted into the same right arm I had cut off. It had shapeshifting powers which I had already seen awakened before when it generated scales, claws, and horns.

I quickly stood up, testing my arm. It was moving alright, reacting to all my commands as I had wanted!

"It is done!" I exclaimed, feeling completely fulfilled.

"Are you sure you're alright now?" Eleanora wondered.

"Of course I am- Ugh?!"

However, something unexpected suddenly happened, as the palm of my demonic hand shapeshifted, an enormous eye emerged on it, looking back at me, and then a small mouth appeared, speaking.

"Bring me blood! Bring me slaughter! Destruction! Massacre! Kill!"

"Ah, great, it has a will of its own…" I sighed.

"It can talk…" Eleanora muttered.

"Sigh, I guess there's no power without risks." I said, looking at the arm. "Shut the fuck up now. Sealing Chains."

FLASH!

Transparent chains emerged, chaining the entire hand, and then becoming invisible. The arm struggled, but it remained in silence after a bit.

"That should do it…"

And then, without realizing, I fell unconscious.
