Vampire Summoner's Rebirth: Summoning The Vampire Queen At The Start

-----

I took out the items from my bag, I had prepared a large assortment of materials that I butchered out of the bodies of the demons. Before sending the Blue Oni head to the Duke, I cut off most of his hair, horns, fangs, and his two eyes, that's because those materials had a large quantity of demonic energy concentrated into them. I had also decided not to cut down his ears because that would make him way too unrecognizable.

​ Aside from that, I also had a lot of demon bones, which were obviously stronger than normal monster bones from here, and the bones of demons were of various colors, not just white, the Blue Oni's bones were actually black-colored, and the Imps often had red or orange bones.

Strong enough demons have bones so hard that they are made of metallic materials, often called Demonite Calcinate, which was the name of the material that was sold in the vast outer universe auctions, the metal extracted from demons' bones is a strong and durable metal made to even build high-grade spaceships and weapons that can harbor demonic energy.

Since the invasion of the demons into the vast Universe that the people began to utilize their bodies as materials, and over the eons, demonic energy became a widespread energy that was used for all sorts of technology, of course, I know a lot of all of that. I wasn't the best at machinery though, but I know enough to at least make a spaceship, mechs, and demonic technology weapons, all of the most basic stuff, I am a novice after all as I was more of a battle-oriented leader while I left the rest of the work to my subordinates… If I ever am able to summon one of those that was in charge of machinery and more, I might be able to recreate it here, although it will be a long and methodical process.

Nonetheless, aside from the Blue Oni Materials, I also had another assortment of materials. The blue and red skin of the Oni and the Imps was a precious material for alchemy as well. Their internal organs that are often not eaten also save secrets.

The stomach of a demon has a unique assortment of enzymes and bacteria that allows them to devour and assimilate all sorts of energies and transform them into demonic energy, and they're often called the "Demon Acid" out there, it was a special fluid used to convert other sorts of energies, be it Mana, Qi, Aether, Cosmic, and more energies into Demonic Energy.

For now, I don't have the healthy means to extract it, so for now I am using the internal organs raw into the preparations I am going to make… Lastly, there is a special organ, the demon heart. It is not just anormal fleshy heart, it is actually made out of special muscle filaments capable of pumping demonic energy across the body at an increasing speed, the more excited they are, the faster it pumps demonic energy, this is why it is often used to create another liquid named "Demon Conductor" that can conduct demonic energy.

And well, how to forget the prize of that day… I've been maintain this from rotting alongside the other materials, it is a yellow-colored eye I extracted from one of the Elite Imps, it is the Demon Eye of Paralysis. It was not a surprise to learn that by using special procedures, you can replace one of your eyes by a Demon Eye, and if things go well and the heal is successful, you can even gain its powers.

I plan to put this eye into my left eye.

I have already done countless surgeries before in my previous life, mostly to heal allies or myself, as I was a Vampire with great regeneration, it was easy to modify my own body and add new organs and so on, I was constantly infusing demon eyes into my body, and I could switch them around based in the situation, of course, that came with the physique of a True Vampire God, something I am not anymore. The most I can afford an eye through a painful method, but there is Eleanora to assist me in the operation.

A Demon Eye of Paralysis is very strong, and it would help me greatly, the thing is, to add it into my body I require to be able to harness demonic energy… and this is why I am going to start to make my body get used to it by making some Demon Potions that heal Demonic Energy into the body, they will directly infuse a clean and high-quality amount of demon energy into my body, which is specially made to not be as harmful as the normal one.

The procedure is simple, I will constantly drink these potions to gain demon energy and force my physique to absorb it and adapt it into my body, it will be painful, but the results should come in a few days… I also think that it might be even faster as I have Heavy Drinker, which also has the passive effect of making toxic drinks less toxic the higher the level of the skill is. So it is ideal for me.

The other method would be to make a demon core but putting one inside of me when I already have a Spirit Orb might end up in catastrophic ends, so I won't do that for now, it is better to just make my own body absorb the demonic energy through my physique, and also do the same with my soul. I don't need to produce it, storing it is enough, and that can be done through extensive practice, nothing hard.

"Wow, you got such a big assortment of items…" said Erika. "T-These are all demon parts?"

"Yeah. I plan on making some potions for me." I said. "I want to try out something…"

"Something? I wonder what!" said Erika curiously. She still had the mind of an innocent child very much, so she often spoke very childishly, but that only made her more adorable.

I petted her head and smiled.

"It is a secret, but I will show it to you when I am done."
