Team Zero's Journey to Another World

After a space gate unexpectedly opens, the Yongfang Alliance and the Star Spirit Empire engage in warm and friendly exchanges (they fight the moment they meet), followed by friendly trade (exchanging benefits). The Alliance sells off its ordinary ancestral books (red ideology) as if by chance (with no intention of exporting it), then engages in exchanges of ideas (revolution) (exporting them), and thus sets the other world on the path to progress (reform).
