Once one is built, there will be one less. When the main anti-magic stone mining areas on the continent can no longer produce anti-magic stones in large quantities, even if some forces unlock the technology for building Floating Cities, it will inevitably lead to a harsh problem, which is that they will not even have the raw materials to construct Floating Cities.
In other words, these raw materials have become so expensive that ordinary forces simply cannot afford to consume them.
Of course, this issue is not as critical to other nations, because countries like the Yibel Federation, which were involved in the initial Floating City program, had the foresight to start a large-scale harvest of anti-magic stones, even from foreign and lawless areas, while other nations were still unaware.
Especially the Yibel faction, because Kael had communicated with the federation's upper management on this matter long ago.
