4 years passed in the blink of an eye.
I got summoned 8 more times and my bank was now at 43%. I finished studying the System in just two days and started to improve it.
Since I had hit a bottleneck, I decided to leave my cave and explore the Demon Realm. I did so for two years and learned more about the Structure of this Universe and the surrounding ones.
The Demon Realm was ruled by one or more Demon Gods, not much is known about their numbers, beneath them were the Demon Kings, Princes, Dukes, Marquise, Counts, Viscounts, Barons, lords and finally Knight, in this order.
From what I heard, Demon Lords are often send to other Universes to collect souls and other valuables for their superiors, some even go there willingly to get better chances at getting promoted.
Considering that the ranking is mostly based on strength with only a few exceptions, the Demon Lords that often appear in the fantasy world are weak. It is very rare for someone with a higher rank to get their hands dirty themselves, so it falls on their vassals.
I also heard rumors about Demonic Dragons residing in the depths of the realm and I wanted to meet them because from what I had gathered they were the real deal.
I had encountered 'Dragons' in HP and Britania but they were either just winged lizards or too weak to actually be called such. The Dragons here however were a race that existed since the beginning of their Universe of Origin and each of them was a force to reckon with.
They were the size of a mountain at average, had scales that neither magic not blade could harm, their eyes could see beyond the veil of the world and supposedly are the source of their immense wisdom and all dragons had a Dragon Heart that produced untold amounts of mana each second.
These Dragons were close to the World or Hidden Bosses in games than the lustful and weak creatures that only served to make the MC look more powerful or give him a reason why he needed a harem.
They were everything I wanted a Dragon to be and more and I couldn't wait to become one of them.
Over the years I have done some minor changes to my demon form, mostly making it look less average and more demonic but also increasingly powerful with me currently being MCU Hulk level. Stronger than the average unnamed demon but still only average for a demon who had powerful ancestry.
My last summon was by some crazy teens from a modern Earth, who thought trying to summon a demon was cool and even better when human sacrifices were needed. To be fair they didn´t actually think it would work, actually wouldn´t that make this worse? Anyway, since they saw it work they wanted to get a wish fulfilled. I wasn´t a fucking Genie but their wish for Immortality amused me, so I granted their wish. Of course not without a catch, I used the modified immortality curse I made in Nanatsu no Taizai and included a curse of misfortune. Now they are going to life forever but always be poor, never find love, have one incident after another or have anything good happen to them.
I was currently going to a place ruled by a Lord, simply because although I was plenty entertained by my most recent summon I wanted my name and for that I needed to be summoned. This Lord was tasked by a Viscount to invade a world and harvest it and he was currently recruiting demons.
Unnamed were mostly used as cannon fodder but they still accepted because unlike a summon, the Demon Lord had to continuously supply us with mana as pay and that mana went straight into the naming bank.
There weren´t just unnamed joining of course, there were also name and Knights that acted as Elites or Generals, thought I wasn´t sure what they were paid with since they already had their true name and I couldn´t find any information on that, I suppose I will know once I too become named.
I enlisted smoothly since there were absolutely no requirements but since the departure was still a few weeks away, I was given a cottage I had to share with other recruits till then. This was strangely similar to human society, except of course that there is no democracy here and everything is ruled by the strongest fist, or claw.
The weeks passed and it was time for the invasion. I could feel the bloodthirst radiate from every being around me, it was understandable since we don´t get the opportunity to feast on delicious human blood and kill indiscriminately often. I already started to enjoy blood after I assimilated vampires and after assimilating several demons this only increased, especially human blood.
So, here we were, standing in the millions, outside the weird looking barracks where a silver blue portal had formed. This was created by the Viscount who gave the order and I could feel that it was way smoother than any other summon I have had till now, in fact I might even say perfect. It was a show of both power and skill, skills that gave a glimpse of how magically developed the Demon Realm really was but since I wasn´t even named I didn´t even have to right to officially enter the demon society and learn it.
The Lord was the first the enter and after him his Knights, followed by Named demons and the rest after them.
They didn´t need to send fodder first since they hundreds of times stronger than unnamed, that's just how much power getting a name gave them, not to mention the magic they had access to since they officially joined the society. I didn´t think that my growth would be as drastic as theirs but it should at least make some changes in me.
