When the Wandering Alliance and the Dense Civilization went to war, the distant Metal Civilization remained relatively calm, with everything proceeding in an orderly fashion.
During the research collaboration with the Metal Civilization, whenever it was time for a break, a large number of scientists took the opportunity to seek guidance from the Metal Planet Wandering regarding the Communist system, showing great interest in knowledge related to Communism. They even equipped the space research station floating above the Metal Planet with a live broadcasting device to stream lectures by the Wandering to all the people of the Metal Civilization.
To be honest, even the Wandering itself did not anticipate this situation.
