Comments of chapter undefined of Lord of the Truth

okay that's kind of strange that they are fighting at four places at the same time. Unlike Robin who Has just started his empire and got to know exact location of a few worlds . They should have exsisted for substantial amount of time and discovered new worlds over long span of time and not nearly simultaneously like Robin . So did they encounter forces backed by other powerhauses from middle planetary belt on each of those planets or is cost of logistics too high to move huge armies to conquer the worlds with no particular resources since even if they conquare them like that they would end in red ?
