The "Records of the True Profound Dao Ancestor" also further described the grading of the Primordial world itself.
According to the True Profound Dao Ancestor, the Primordial world was divided into five tiers: Low-tier, Mid-tier, High-tier, Top-tier, and Supreme. It is important to note that this is a classification of the entire Void Sea's fictional worlds, not an internal division within a fictional world.
A Mid-tier Primordial fictional world could contain one, two, three, a hundred, or even countless Primordial worlds within itself.
That is, a Primordial fictional world could very well contain many Primordial worlds, and the classification of these internal Primordial worlds could also be divided into Low-tier, Mid-tier, and High-tier.
It was like nesting dolls.
However, it is important to note that this Low-Mid-High tier standard was merely an internal classification within a specific Primordial fictional world, and had no relation to the classification standard of the entire Void Sea, with many differences.
On page seventy-nine of the "Records of the True Profound Dao Ancestor," the fundamental appearance of the entire Void Sea was recorded separately.
In the shallow regions of the Void Sea, Level 1 fictional worlds were widely prevalent, along with a small number of Level 2 fictional worlds.
Level 1 fictional worlds, also known as Low-tier fictional worlds, were fundamentally incapable of moving their world coordinates, nor could cultivators leave these worlds to enter the Void Sea. Essentially, they could only be passively influenced by higher-tier worlds and lacked the ability to actively invade other fictional worlds.
Therefore, they could be disregarded.
These types of fictional worlds were distributed like stars in the shallow regions.
The High-tier pseudo-immortals in Level 2 fictional worlds, in order to obtain more generalized spiritual energy and all forms of energy, would advance to higher stages.
They would use their worlds as ships, sailing through the Void Sea, searching for fictional worlds to devour, thereby obtaining more energy.
These types of fictional worlds were also known as predatory worlds. Predatory worlds would do their best to find suitable fictional worlds to prey upon, but many Level 2, or Mid-tier fictional worlds, would remain stationary at their Void Sea coordinates and not move.
It was observed by the True Profound Dao Ancestor himself that these types of fictional worlds had a more than ninety percent chance of gradually moving deeper into the Void Sea to hunt. Many powerful beings discovered that the deeper they descended into the Void Sea, the stronger the fictional worlds became, and the higher the energy levels, which meant that pseudo-immortals would evolve towards greater strength.
In this process, Low-tier fictional worlds, which were defenseless and harmless, would gradually decrease, replaced by more Mid-tier fictional worlds.
Unlike Low-tier fictional worlds, which were powerless against predatory worlds.
These Mid-tier fictional worlds possessed a certain degree of anti-predatory capability, and some were even stronger predators themselves. The outcome of a collision between two predatory worlds was uncertain, and it was easy for the invader's world to be preyed upon in return.
During this process, Mid-tier fictional worlds would slowly move from the shallow regions to the deep regions. This process would continue until the pseudo-immortals comprehended infinite energy, created something from nothing, and achieved the status of true immortals, at which point they would cease their predation and transform from plunderers into eternals capable of generating infinite energy themselves.
Of course, there was also a possibility that the deeper they went, the more they discovered the vast number of powerful fictional worlds in the deep sea regions, like stars. The pseudo-immortals who preyed on worlds would feel fear and thus, instead of moving further down, they would swim away from the deep sea regions and return to the shallow regions.
In the deep sea regions, Low-tier fictional worlds no longer existed; only numerous Mid-tier fictional worlds and many High-tier fictional worlds guarded by true immortals were present.
In the extremely deep sea regions, even Mid-tier fictional worlds would not exist. This was the dwelling place of cultivators at the infinite energy level, where only High-tier fictional worlds existed.
Cultivators at the infinite energy level were also known as: Eternals.
Eternals typically did not appear in the shallow sea regions, because at the origin of everything, the Supreme Primordial, the Mythological Primordial, resided at the very center.
Eternals would generally try to get as close as possible to the Mythological Primordial, and as close as possible to the Supreme Primordial.
The shallow sea regions and the shallow areas of the deep sea regions were not illuminated by the Dao light of the Mythological Primordial. Only by entering the extremely deep sea regions could one feel the Dao light radiating outwards from the Mythological Primordial. This Dao light, by understanding the Dao of the Mythological Primordial, could transform an outsider path cultivator into a righteous path (Primordial method) cultivator, which was very beneficial for Eternals to further advance.
On page seventy-nine of the "Records of the True Profound Dao Ancestor," the distinction between outsider paths and righteous paths was clearly stated.
The cultivation method of the Supreme Primordial was the righteous path, meaning the orthodox Great Dao.
Any method other than the cultivation method of the Supreme Primordial was considered an outsider path, referring to a path that deviated from the orthodox and leaned towards side paths.
The orthodox Great Dao was difficult to comprehend and cultivate, yet it was the only path to attain the supreme Great Luo fruit status.
Due to the great interest many Primordial Great Luo Immortals had in imparting their teachings, the radiance of the orthodox Great Dao was often spread across the many fictional worlds in the extremely deep sea regions.
Beings who survived in these fictional worlds did not need bloodline support, nor so-called innate talent. As long as they were enveloped by the Dao light transmitted by the Great Luo Immortals, they naturally had a chance to cultivate to infinite energy.
In the extremely deep sea regions, three boundaries could still be demarcated based on the depth of the sea region.
The closer one was to the boundary of the Mythological Primordial, the more the number of immortals would noticeably increase, and worlds filled entirely with immortals were common.
Furthermore, the rank of the immortals would become progressively higher.
The third boundary, the area closest to the Supreme Primordial, contained a certain number of outsider Profound Immortals who comprehended the Profound principle, and orthodox Profound Immortals.
However, cultivators from outside the Supreme Primordial could at most cultivate to the Taiyi Dao fruit.
To advance further on the path, one's true body needed to enter the Supreme Primordial.
However, listening to the Dao in the Supreme Primordial from beyond the boundary, and residing long-term in the Supreme Primordial with the permission of the Great Luo Immortals of the Supreme Primordial, were clearly different.
On page seventy-nine of the "Records of the True Profound Dao Ancestor," the True Profound Dao Ancestor often lamented his lack of opportunity and qualification, which was why he could only reside in the True Profound Realm and not settle in the Supreme Primordial.
Even though the True Profound Realm was bathed in Dao light, it was not as good as residing in the Supreme Primordial, with its never-ending sound of preaching.
Such was the complete picture of the Void Sea. The further down one went, the closer to the center; the further up one went, the more remote and desolate. According to the True Profound Dao Ancestor's own exploration, by continuously moving upwards, beyond the extremely shallow sea regions where worlds were extremely weak even within Low-tier fictional worlds, all that could be seen was no longer any fictional world, only the vast Void Sea.
In sea regions where even fictional worlds did not exist, moving further upwards would forever reveal infinite Void Sea, and the end could not be reached.
