Many years later.
At the peak of the Tenth Dimension.
Supermassive devices more numerous than the Fundamental Particles—quarks—within the Matter Universe had formed a special array and were roaring in unison here.
Beyond that.
Countless deep-blue pillars of energy, like raindrops, ceaselessly streaked through this spacetime under the influence of some force.
They were the energy successfully plundered by numerous advanced civilizations only after draining different Worldlines and destroying the universes, dimensions, and planes within them one by one.
To better manage them and the various devices.
Figures whose bodies alone were as vast as star rivers continually wandered through this place.
Making extraordinarily complex adjustments to every device and energy pillar.
With every moment of thought, they calculated an unknown number of formulas, further optimizing and adjusting the current plan and its efficiency...
And at the very center of it all.
Within the core region linked together by countless pipes, displays, runes, and more throughout the entire ten-dimensional space.
Inside a structure resembling a colossal metal tower.
The main base of the World Forgers—a special research organization composed of the foremost technical personnel from numerous civilizations—was located there.
Looking inside.
Within the giant tower.
Powerful Lifeforms whose bodies were no longer purely material in nature were carrying out the final step of the Ark of the Mortal World Plan at a feverish pace.
At this moment.
Although many powerful beings had been unable to personally arrive for various reasons, their gazes still crossed spacetime in perfect accord and converged here together.
At the same time.
Vast layers of power drifted forth from each powerhouse, like mighty barriers cycling and stacking atop one another, further reinforcing the secrecy of the ten-dimensional space and forcibly isolating the Spacetime Structure of the Tenth Dimension from that of other regions.
In truth.
