Of course, that was a capacity that was never reached by the average human. But when it came to the mages, sorcerers, priests, and many other powerful people of Lucius's past world, that limit was not unreachable.
Usually, how the brain worked was that it would push out or delete older and unused memories to make room for new ones. This way it would never run out of space as it would keep on cleaning the storage.
But this was a problem for the stronger mages.
To mages, their memory was one of the most important things to them. All of the things that they learned, whether it be magic theory, spell matrices, spell forms, runes, scripts, curses, and many more things, they all needed a lot of memory.
While it was not often, there were actually mages that ended up reaching the limits of the human brain. Of course, over the years there were many solutions to this that had been researched by the scholars.
There were means such as magical herbs and medicines that increased the brain's capacity, technological assistance in the form of implanted chips along with artificial intelligence that could asset them, genetic modifications along with magical modifications that could be made as well.
Even the priests of Thara were not free from this and needed the divine grace of Thara to boost the capacity of their brains. In all these options, at least during the time period that Lucius lived in, technological solutions were the most affordable and were used by nearly everyone.
It didn't matter whether they were a commoner or a mage, they all used tech to assist them in daily life. The magical means of enhancing brains were a bit more complex and were not possible for everyone, as it was needed for someone to be a mage themselves.
But even if there were all these solutions, not everyone was satisfied by it. There were those powerful beings at the top that did not want the assistance of external means and had already exhausted the magical means of doing so.
Thus, they wanted to tap into the hidden potential of the human soul. That was where the soul theory came from and how it was expanded upon. If one were to make a comparison, the soul was like a software that could not exist without hardware, which was the body.
But along with this, it was a software that could adapt and grow with the only thing limiting it to the hardware itself, i.e. the body. Once this point was established, the top mages of the words tried to find ways of raising the limits of the soul.
They did find a few solutions to it eventually and even used them. One of them was nothing but soul transplantation. Putting their souls into a body that was better than their previous one.
Then there were a few that chose to put their souls into puppets instead. They had many names, such as golems, cyborgs, clones, avatars, etc. But they all had the same function, of having a secondary body.
Of course, they came with their own set of problems, but that is a topic for another time.
What Lucius grasped from this was that perhaps traveling in the soul form while being stable for so long may have allowed it to grow beyond what should have been possible. It was now that Lucius was reminded of his wish.
'I asked the Amulet of Barrom to make me the strongest in the world while Mira's wish was to prevent that. But the sacrifices had already been made and debts were paid. The Amulet Of Barrom contained the will of the Great Demon Barrom. There is no way it would have denied one wish in the favor of other.
It told that it would balance one bargain against another. What if… this is what it gave in exchange?' Lucius thought to himself as a serious expression appeared on his face.
He then recalled the exact wordings that Mira had used while asking for her wish.
"May the soul of Lucius be forever unable to gain power in 'this world'." Lucius recited.
After saying that, Lucius went silent for a bit. But then…
"AHAHAHA! AHAHAHA! Mira, Mira, Mira… You gave me an even better option than I could have asked for. Now I don't know whether to curse you or thank you!" Lucius laughed out loud.
Lucius finally understood that the Amulet of Barrom did the best it could within the parameter that had been set by his wishes. Since his wish was for being the most powerful in the world and Mira's was that he could not gain power in that world, the Amulet simply sent him to a different one.
"The worlds and dimensions I saw… was that the amulet's way of compensating me? Lucius wondered as a smile appeared on his face that would probably terrify most people.
While the smile itself was quite normal as how novena would smile, but the aura that it emanated was nothing normal. It emanated an aura of ages, of experiences of power and of chaos.
This was not something a human could have. But just as the aura appeared, it disappeared in the next moment. Neither Lucius nor anyone else felt that aura nor saw it.
Having understood everything, Lucius felt a bit pleased. If there was one thing about power, he knew was that Knowledge was one of the pillars of power. If one could have knowledge, they could find other ways to gain power.
And Lucius currently had more knowledge than perhaps anyone in this world. Sure, it was not the knowledge of this world, but he had learned countless things from the many worlds and dimensions he had seen.
"Of course, the Great Demon Barrom would not make a mistake. An artifact like that is absolute and the human quality of error and mistakes do not exist for it." Lucius said with confidence.
"Now I just have to capitalize on it. Though for that I will need to establish a foothold on this world… a stable and unshakable one!" Lucius declared.
