At the same time, Lord Gerstahl Lucifuge was relying upon a message to Lucifer about events that transpired in the Helheim.
Hearing this, Lucifer's mood turned unusually good, hearing all of that. With the addition of Hela's army to the Underworld, he was even more confident of crushing Heaven and Grigori to the ground. Completely unaware by plots and schemes for his death by his own blood.
"Send out the Decree that I rise noble rank of Zeoticus Lucifer to the Grand Duke for his merits in securing such enormous help for devil kind in the war against our eternal enemies."
Siad Lucifer with a commanding voice.
***
One day later, as I was relaxing in my gardens, I received a decree from Lucifer that I have been promoted to the Grand Duke Noble Rank.
This was good, as now, I was socially one of the highest-ranking nobles in the entire Underworld. I planned to be promoted to at least King Rank before the war starts. After I reach Satan-Class and secure assistance from Takagahamara in wiping out Church from Japan, I can predict that Lucifer would promote my rank once more.
That would be for best, as then I would be automatically placed as one of the military leaders of the Great War on the devil side, or I could make my own army and be completely independent of the chain of command, like Great King Bael.
Now, before I planned to take Vena on a date to Agreas, I decided to make use of Divine Sparks and corpsed of Lesser Gods that I have obtained on my trip, or killing spree in the Helheim.
As usual, I planned to brew potion out of the body parts of the gods. While my Alchemy skills weren't that bad, they were pathetic compared to the real Alchemy that was practiced in the Astral Boundary.
Fortunately, the corpse of Vidal could be processed separately into several potions, as it was too potent compared to Lesser Weak Gods.
Potions refined from corpses of these Lesser Weak Gods would tremendously improve my physique, as the Divine Path of God was well known for balance between physical strength and energy reserves. Every power system has its own advantages and disadvantages.
Divine Sparks of the Gods could be used for other people to ascend or be used in various rituals or weapon refinement.
I planned to use half of the Divine Sparks I have obtained in ritual to combine it with a potion. I calculated it should strengthen my physique to the pinnacle of the Ultimate-Class. Of course, if somebody who was specialized in physique and was the so-called body cultivator could reach a much higher level than me from this procedure.
In truth, what I was doing, was considered as extravagant mad wasting of resources in Astral Boundary. Nobody would waste six corpses of Lesser Weak Gods and their Divine Sparks to strengthen their physique. Only a very few factions could do something like this.
Similarly, Vidal's corpse and Divine Spark would be used in the same way, in the hope to strengthen my physique to Satan-Class. After that, I would be considered as one of the top powerhouses in the Draconic Deus, and by Astral Boundary's standards, I would be a heaven-defying genius.
As I reached such a level of power just within 200 years, which was a short time. And in reality, it was only ten years or so from my transmigration.
I started preparing my potion ingredients which were corpses of the Lesser Weak Gods. To prepare it, I instructed Architect to dissect them for crucial ingredients: Blood, Heart, and Bone Marrow. Every part of the god's body was brimming with energy and power; I could feel it with just a look.
Usually, Lesser Weak God has no problem killing Ultimate-Class powerhouse with ease, but thanks to my carefully planned trap, they all fell at the same time. Even Grade 7 Plane accordáing to the classification of the Astral Boundary has limit only 10 Gods...
I then dropped everything into the huge cauldron and activated a magical formation around it for it to brew under immense heat. While I wasn't a very skilled Alchemist or Potion Brewer, which was a sub-class of Alchemy, with the Architect's help, it was effortless for me to produce potions from zero knowledge.
Within the next ten hours, I have spent brewing the potion, adjusting the heat, or adding some additional ingredients like some Mid-Grade Energy Crystals, parts of Monsters, and other things to boost up the efficiency of the potion.
I was slowly preparing for the moment when I would enter the Astral Boundary, which was a real stage, not something like Dimensional Gap, which was a sealed space consisting of only a few tens of weak planes.
I have also decided, in the future, I should target planes where gods were abundant and hunt them for resources when I would be strong enough. Maybe even kill as many of the gods in Dimensional Gap; they would become my nutrients or for my followers and family.
Sadly, I cannot use Devour on the Divine Spark, as the Divine Energy is too contradicted to the Demonic Energy, and it would cause me serious injuries due to energy deviation.
Soon enough, the potion was finally finished, and I have obtained four bottles of it altogether.
"Hmm... I will use one on myself; two could go to Vena and Grayfia. They would be participating in the Great War, so it would be good for their strength to increase. Last one I will give to Hela. I need to have her on my side, as her soldiers are currently the majority of my army."
I said to myself.
