Beneath this peculiar substance, each world within the myriad heavens and realms was insurmountable.
Previously, in worlds like those from the Foundation or the Time-Space Administration's multiversal narratives, powerful beings such as the Three Heavenly Emperors of the Sacred Ruins or Meng Qi of the Dao Fruit realm could perceive and interact with other worlds.
If the myriad heavens and realms did not communicate, why would the Time-Space Administration have established various laws for "smugglers"?
In those multiversal worlds, the myriad heavens and realms were traversable by those who had mastered certain spatial technologies.
However, this realm, a multiversal expanse of seven-layered boxes, was different.
In this multiversal expanse, each world was separated by a peculiar substance. Even powerhouses like the Three Heavenly Emperors of the Sacred Ruins, Luo Feng the Primal Lord, or Fang Lao Mo of Eternal Life could absolutely not cross this peculiar substance to reach other worlds within the myriad heavens and realms.
"Relatively speaking, a closed multiversal expanse?"
Fang Ming saw that in this multiversal narrative world, only the protagonist could transcend the limitations of the peculiar substance and travel to other worlds by virtue of his system.
Apart from the protagonist, no one else, no matter how strong, could break through the boundaries of worlds.
But Fang Ming had no desire to descend into this multiversal narrative world.
This was because the higher the level of a narrative world, the more the protagonist within it possessed temporal abilities.
At this moment, in the Void Sea, the protagonist he observed in the multiversal narrative world was only at the nine-star level.
Yet, Fang Ming distinctly felt an immensely majestic aura emanating from him.
If he were to descend into this multiversal narrative world, he might have to face a protagonist at the seven-layered box level in the future, rather than this nine-star level protagonist.
"Temporal abilities..."
Fang Ming was not afraid of this protagonist at the seven-layered box level.
Narrative worlds that were "islands" would have no awareness of the Void Sea and would not step out of their own worlds.
Unless Fang Ming personally entered, he would be safe from the protagonist's attacks while remaining in the Void Sea.
However, this was only true for "island" worlds.
"Island" narrative worlds had no communication or contact with the Void Sea.
But for open narrative worlds, those with Void Sea technology, the powerhouses within them were capable of contacting the external Void Sea.
And such worlds...
Fang Ming was startled.
In this deep sea region, Fang Ming saw a colossal world.
Within that colossal world, countless powerhouses were faintly visible. Beings at the Dao Fruit realm, or even above the Sacrifice Dao realm, were merely cultivators manufactured on an assembly line in mere seconds within this world.
In this world, any ordinary mortal could use the ubiquitous assembly lines for body production to create a physical form for themselves that possessed the strength of the Dao Fruit realm, above the Sacrifice Dao realm, or even the Primal Lord level.
Mortals without supernatural powers could, through the might of consciousness technology, create bodies and primordial spirits, and control them perfectly.
This was a world where an ordinary mortal could ascend to the four-layered box level in one second.
It was also a world where everyone had achieved the four-layered box level of strength.
Such a civilization, it could be said, possessed the strength of the Dao Fruit realm, or even beyond, for any ordinary person.
"Such powerful black technology..."
Fang Ming possessed his own insights. He could feel that this so-called assembly line was closer to technology, even a sci-fi-like civilization, compared to other cultivation systems.
This sci-fi civilization was exceptionally powerful. Fang Ming estimated it to be at the eight-layered box level. Ordinary eight-layered box powerhouses would likely be captured within a short period if they entered.
More crucially, Fang Ming realized that within this sci-fi world, there were individuals who had comprehended Void Sea technology. This sci-fi civilization was not trapped on an island; it was a civilization capable of invading the Void Sea.
These bodies on the assembly lines, which did not belong to the sci-fi cultivation system, were acquired from other narrative worlds within the Void Sea.
—Fang Ming saw that in the Void Sea region near this sci-fi world, there were various defensive measures of this sci-fi civilization, indicating its capability to venture into the Void Sea.
"It's time to retreat. I cannot venture further into the Void Sea."
Fang Ming's avatar had already developed a desire to retreat.
The deeper one descended into the Void Sea, the more terrifying the worlds encountered, and the greater the number of worlds possessing Void Sea technology, becoming open worlds.
Open worlds were further divided into fully open worlds that understood the Void Sea's structure and semi-open worlds that only contacted a partial area of the Void Sea without understanding its overall structure.
Fang Ming did not know whether this sci-fi world only contacted a partial area of the Void Sea or if it was a fully open world that already knew of the existence of the Myriad Worlds Tower.
With insufficient strength, Fang Ming did not intend to delve too deep into this abyssal sea region.
He should stop advancing and stop descending now.
Fang Ming, with his mere three-layered box strength, was truly unable to resist a world where everyone possessed four or five-layered box strength, where even ordinary people started with four-layered box strength.
The number of trillions, countless, and innumerable thirteen-star level powerhouses was not something Fang Ming could resist at this moment.
Normally, Fang Ming, with his three-layered box strength, would inevitably be captured by this sci-fi world and become one of the countless research materials in their laboratories.
Fang Ming was able to avoid being discovered by the powerhouses within this world, after he himself had discovered it, thanks to the existence of Fu Meng.
However, Fu Meng was not invincible.
Fu Meng was a true spirit lifeform.
But it was also an eleventh-tier true spirit lifeform that was heavily injured.
It should be called a pseudo-eleventh-tier true spirit lifeform.
If it encountered a genuine narrative-layer being, Fu Meng would not be able to protect Fang Ming.
And in the deep sea region, there existed narrative-layer beings of thousands of layers.
The powerhouses of the Void Sea's myriad worlds were engaged in a fierce battle with the Myriad Worlds Tower. If he insisted on going deeper, he might encounter the war between them, which would be a certain death.
Fang Ming then cast one last look at the terrifying multiversal narrative worlds and the single-system worlds around him before dissipating this avatar.
In the Void Sea, the deeper one ventured, the greater the danger. Fang Ming, with his mere infinite-multiverse level strength, was truly incapable of deep-sea operations.
The shallow sea region below the second-layered box, multiverse level, was accessible.
The second-layered box, multiverse level, the third-layered box, infinite multiverse level, the fourth-layered box, thirteen-star level... up to the tenth-layered box sea region, was also accessible.
But he should not go any further down.
These worlds might not all be islands, nor were they worlds like the Primordial World, lost in the mist of the Void Sea...
