This massive metallic platform is a Void Base operated by the military, resembling an interstellar space station from the space age, with a diameter of about fifty kilometers and a correspondingly colossal volume. At this moment, around the edges of this vast space station, numerous small flying vehicles can be seen coming and going.
Every time the Main World conquers a group of planes, a substantial Void Base is established as an Outpost Base there, generally varying in scale and importance.
Lin Xiao knew that these Void Bases are typically categorized into five levels, with First Level being the lowest and Fifth Level the highest. The Void Base they were currently at was a Level 2 Void Base.
But above this Level 5, there are even higher levels of Void Bases, for specific reference, one can consider the Yan Huang No. 5 Super War Fortress.
