This Is the World That Travelers Dream Of

This is a world that countless travelers dream of. Ordinary people are not qualified to compete with octopus men for the job of wiping [nobles'] butts. Mainly because it has suction cups and loves to be clean. Most of the foot-warming maids are [Tiger Slough], who are warm and respectable. What kind of bicycles should be developed? Wouldn't it be nice to ride a [centaur]? What aircraft should be developed? Wouldn't it be nice to ride a [Dragon Man]? Human beings really can't find a suitable position, so they have no choice but to join the protagonist's yellow tide, overturn a strange family, and become a noble from now on.
