To begin with, as the fundamental problem, there exists the fact that passages for invading into the Otherworld are not easily discovered.
Only during special great disasters such as spacetime oscillations something that may or may not occur once in a thousand years do rifts in spacetime open for a short time.
With this, dispatching a large army is impossible.
At best, it was all they could do to send in an advance unit and have them construct a base.
However, in this world, exceptions also exist.
Several rifts that connect spacetime are fixed in the world and were fulfilling the role of “gates.”
Those are what are called “Netherworld Gates” or “Hell Gates.”
If one uses those “gates,” escaping from the Otherworld would also be easy.
However, since the “gates” are under the control of the demon race (demons), their use by the invading species (aggressors) is not permitted.
From Cornu’s perspective, they are nothing but stories that he cannot accept.
Feldway’s true objective in trying to rule all dimensions and all worlds was because he intended to revive the god Veldanava.
And, through complete domination, he was thinking of eradicating all misfortune.
Although it was an extreme ideology of eliminating those who do not submit, if one follows the way of thinking that power is justice, that too was one form of an ideal.
And Cornu was one of those who had convinced himself that it was correct.
Unlike Obera and Zalario, he was the one who possessed the closest ideology to Feldway.
The complete domination of all dimensions and all worlds is still far off, still halfway along the road.
This is because, from the axis world created by Veldanava, derivative worlds have been born to such an extent that observation cannot keep up.
So that no matter where, among those other worlds, God might reappear, they could respond. This was the foundation of the ideology.
However, Veldanava, who is God, had already accomplished his reappearance.
Although it is inside the labyrinth, there is a proper reason why it is called the “outer edge.”
That place is a gap between time and space.
Precisely because of that, if the outside of the labyrinth is the axis world, then it is the inside of the labyrinth that is called the “outer edge.”
If pressed by necessity, he considers it good to finish it in a quick strike that was the kind of man Dino is.
That Dino was the first to jump out into subspace.
Following that, Zegion arrived facing Dino.
The first place Velgrynd jumped to was a gap between otherworlds of unknown location.
There, without being bound by time, she faced her own inner self.
By doing that, she made the Ultimate Skill Flame God King (Cthugha) completely her own.
Mai has a lifespan equal to infinity, but even so, there is no choice but to conclude that it is impossible.
After all, the time axis differs for each dimension.
If it is between worlds in a state where the time axes are synchronized, then even if one performs dimensional travel, there is no time difference.
However, realistically, such a phenomenon could not be expected.
Even within the universe of the same world, space continues to expand at a speed exceeding the speed of light.
The correlation between time and space is not within the range of Mai’s understanding.
Much less, the probability of reaching the time and place where her beloved younger brother is alive was something infinitely close to zero, as if it did not exist.
On that day tens of thousands of years ago, the largest and strongest nation in human history, which had been divided and fighting among itself, disappeared from the surface with surprising ease.
The two pillars summoned by Guy had, after all, deteriorated to the level of Arch Demons.
That is precisely the law of this world, and when crossing from the underworld to the semi material world, most of their power is lost.
For spiritual lifeforms, merely crossing worlds is no difficult task, but in this world, even just maintaining existence caused severe exhaustion.
Therefore, Velgrynd remembered all worlds and all Rudras.
