Far away.
Large armies were gathering at different locations.
At one of the assembly areas.
The Superdimensional Battleships, whose basic physical forms alone were large enough to burst the starry sky, floated through the void like stretches of colossal land.
Thanks to the powerful effects of the layers upon layers of energy shields covering their surfaces.
Even the Void Wind that blew ceaselessly could not shake them in the slightest, like a river slowly washing over the surface of a boulder.
Then, under the effects of some force.
Patches of spacetime were created and condensed into shapes resembling transport pipes, connecting the Superdimensional Battleships one by one and allowing all sorts of matter and energy to be transmitted between them at even greater speed.
Looking around, the overly dense spacetime transport pipelines directly added a network of constantly flickering, brilliant veins to the void.
And each Superdimensional Battleship was one of the large and small nodes within this network.
At this moment.
As vast quantities of matter and energy were rapidly transmitted without pause.
Under the control of special equipment, the Intelligent AI aboard each Superdimensional Battleship began carrying out the tasks already assigned to its programs: upgrading and replacing the various equipment within the Superdimensional Battleships.
As for the so-called equipment.
It was itself a combination of energy and matter.
With detailed blueprints available, there was no need for so-called engineers or designers. Each Superdimensional Battleship could use its own engineering equipment to rapidly upgrade itself.
The whole process was convenient and swift. It did not require much effort at all, nor did it require an equipment factory.
As for this aspect, throughout the vast upgrade process, the Superdimensional Battleships that wielded advanced technology were not picky about the various types of matter and energy. They did not care
