Isekai Adventure in the Dimensional Cube-Chapter 1519 - 1063: Are They Really That Weak?

Before this, Beluti also mentioned that Night Spirit is an extremely rare type of magic creature that can only be born in filth.

It usually appears in places full of filth, such as ancient battlefields where massive bloodshed occurred, slaughterhouses, or towns where large-scale plague outbreaks happened. Only in such places where catastrophic events and mass casualties have occurred might a Night Spirit be nurtured.

In the Source World, such places do exist, and there are even quite a few.

However, the place that satisfies the conditions for the birth of a large number of Night Spirits is still only the former territory of "that empire," which is now isolated by the Nanierga Front outside the Source World in the Black Land.

It is the place where the largest and strongest empire in the Source once perished, a graveyard of countless lives.

The battles and casualties that occurred there are countless.

Furthermore, it has already become the largest base of the Abyss in the Source, making it the place most deserving of being called "filth" in this world.

And it’s been thousands of years since the fall of "that empire."

If calculated from when the last savior left the Source World, it’s been eleven thousand years.

Over tens of thousands of years, before this, "that empire" was active at the forefront against the Abyss, and it is natural for the Black Land to accumulate filth and nurture a large number of Night Spirits during these millennia.

Thus, these numerous Night Spirits born have become a weapon utilized by the Abyss.

In Renani’s intermittent and hesitant narrative, Reiger and Beluti finally understood why the so-called Night Spirit Aggregate appeared here.

They were actually intentionally gathered by the Abyss to break through the Nanierga Giant Wall.

Due to the characteristic of Night Spirits parasitizing on living and non-living beings and eroding them, an Abyss Demon Lord has set eyes on them.

The idea of that Abyss Demon Lord is simple: he wants to rely on a large number of Night Spirits to parasitize and erode the Nanierga Giant Wall.

As long as the Night Spirits can parasitize and erode Nanierga, this strongest frontline against the Abyss will collapse without a fight, becoming a gateway for free entry and exit.

At that time, the Nanierga under Night Spirit control would not only cease to provide refuge to the Source but would also cooperate with the plans of the Abyss, gradually advancing the frontlines, bit by bit invading the lands of the Source, causing it to fall.

It’s just that to implement this plan, two premises must be resolved.

One is to solve the control problem of the Night Spirits.

The other is to enable the Night Spirit Aggregate to leave the Black Land and enter the Source first.

The first problem is the most critical because although Night Spirits are a kind of semi-eternal rare magic creature, they lack form, have no biological characteristics, and are innately evil, enjoying attacking weak creatures, more so delighting in torturing them barbarically to death, but that is instinctual and does not mean Night Spirits have intelligence.

Quite the opposite, due to the absence of a brain and spirit, Night Spirits operate purely on instinct; don’t even mention intelligence; they don’t even possess the most basic desires.

While Abyss creatures are mostly chaotic evil beings, they at least have some degree of intelligence, even if only comparable to that of beasts, they at least know what a nemesis is and understand what needs to be done for survival.

Night Spirits, however, do not need that; they don’t require any means to maintain survival, and their nature is actually quite similar to the Abyssal Touch encountered before, being more of a natural phenomenon than a life form.

They are basically impossible to control, not even becoming infected despite Abyssal Aura pollution.

Therefore, not only humans, but magic creatures and Abyss creatures if appearing before a Night Spirit, it would attack indiscriminately, assaulting anything that moves.

In such circumstances, the Abyss Demon Lord must certainly devise a method to control Night Spirits, otherwise, it’s impossible to get Night Spirits to parasitize and erode Nanierga.

The second issue arises from the peculiar nature of Nanierga itself.

As a fortification created by the dwarves to resist the Abyss, Nanierga actually resembles the domain concept found in the world of sorcery.

Typical enclosed domains, once unfolded, have internal strength far better than external strength, with the purpose of trapping opponents entering the domain, preventing escape.

Nanierga follows suit.

The side facing the Black Land is actually the most robust, even if an army of Abyss creatures attacks, even with dozens of Abyss Demon Lords joining forces, it would be challenging to breach Nanierga.

However, due to the extreme specialization of the defensive power on the side facing the Black Land, the side facing the Source is actually far less solid than the former.

Through time’s long passage, the Abyss Demon Lord has essentially figured out that to parasitize and erode Nanierga from the Black Land side, the number of needed Night Spirits, even after accumulating for tens of thousands of years, is unlikely to meet the threshold.

Conversely, on the Source side, if intending to parasitize and erode Nanierga Giant Wall here, the difficulty would reduce at least a hundredfold.

Therefore, besides formulating a way to control Night Spirits, that Abyss Demon Lord also needs to come up with a method to send Night Spirits to the Source, allowing such a large number of Night Spirits to cross Nanierga and enter the Source.
