At that stage, humanity's Engineering Spaceships would spatially seal and package the completed structures, while also installing Space Folding teleportation gates in those spaces. Once Dream Lyra was complete, those gates would become Space Gates inside the battleship.
Through these gates, the people living aboard Dream Lyra would be able to travel to different spaces.
The Engineering Spaceships would drag space itself, like ants carrying food, moving this cluster of spatial modules into the Great Circles, then use targeted Quantum Exile to send them into the predetermined areas.
After that, through String Plucking, these spaces would be fitted together with the Calabi-Yau Manifold, embedding every space into the interior of the Calabi-Yau Manifold. This process would take roughly fifty thousand years.
The final step was to roll the completed Calabi-Yau Manifold back up according to the originally recorded data, turning it into an existence that looked no different from a Calabi-Yau Manifold found in nature.
The entire construction process required macro-scale equipment and the ultra-microscopic domain to work in tandem. The series of operations was almost dreamlike; this was no longer a battleship in the conventional sense.
According to the estimates of human engineers and scientists, the completed Dream Lyra could exist in the Macroscopic Great Universe, and could also freely enter the microscopic world. And because it was itself a Calabi-Yau Manifold, it would display the physical characteristics of a microscopic existence.
This would allow it to move freely through the microscopic world, while also fearing no Dimensional Reduction Strike, because the essence of dimensional reduction was to smash a Macroscopic Dimension into a microscopic curled-up dimension. But Dream Lyra itself could move freely in the ultra-microscopic domain.
A Dimensional Reduction Strike was like a blow that found no purchase against it, light and useless, with no effect at
