The power of the planetary shield can envelop the entire Empire—this statement seems to carry some ambiguity.
After all, as the planetary shield, the Imperial Capital theoretically should be able to encompass the entire planet.
Does such a mere Empire need to construct so many, at least more than two hundred Floating Cities as relay points to spread, in order to cover the entire territory?
In reality, these are fundamentally different matters.
As a planetary shield generator, the Imperial Capital's key function is to use the Aether field to modify the planet's magnetic field and atmosphere, creating a special spirit energy field that can encircle the globe.
This field can block the majority of harmful cosmic radiation, as well as limit exceeding energy attacks. It can also consume incoming comet meteorites or orbital bombardment-like physical ammunition attacks.
