After conquering, the Rounds instilled into the Triangles by repetition, "You are a barbaric inferior race." As the outcome, the Triangles also started to believe that they themselves were an inferior race and regard the Rounds as their masters and beings like gods. |
"The Triangles are an inferior race and the Rounds are more advanced, a superior race"; gradually this fantasy became common sense shared by most of people on this planet. |
