With the current technological capabilities of the Blue Star Civilization, building the Star Disk World is definitely not a problem; it's just a matter of resources.
And owning an entire star cluster, as well as developing two other star clusters simultaneously, the Blue Star Civilization undoubtedly has more resources than the Black Sea Civilization had back then, so the construction of the Star Disk was immediately put on the agenda.
Two hundred years have passed.
Within the Solar System, the structure of the Star Disk has already begun to appear, and a large circular base surrounding the Sun has been formed. It has its own gravitational balance system to maintain the gravitational effect of its massive mass and volume.
The entire base is made of the same material as the core crystal of a White Dwarf Star, and just these materials alone are enough to make ten War Stars!
