Why the Pianuo chose Austria, no one can know the specific reason...
But this alien group has already had a starship land on Earth, and it is clear that more starships will arrive in succession. Thus, just one ruins floating city as a base is far from enough.
They need a vast land to serve as a base for conquering this plane. Even if they don't choose Austria, they will choose another continental land.
As the destination for the Pi Clan's starship and the ruins floating city was confirmed, the whole of Austria instantly descended into chaos...
The officials fled at the first moment, various resources and important assets were airlifted out. They still seemed to want to stay in power, but that was clearly wishful thinking.
Even the land has been abandoned, the so-called Austria is nominally dead, who would still acknowledge its existence?
