On the Mother Stars of both the Bose Civilization and the Fermi Civilization, nearly everyone could witness the war in the stars with their own eyes.
And unlike other civilizations, the Bose Civilization and Fermi Civilization had experienced this war firsthand from the beginning and had personally witnessed and felt the terror of the Wandering Alliance. As the war grew more intense and extensive, this terror turned increasingly into panic.
Since this war lasted for a very long time and went through several phases, the peoples of these two civilizations had lived in panic for an extended period, and when this panic became habitual, it easily gave rise to a deep-seated mentality of worship and awe. Eventually, when the people on the mother planets of these two civilizations saw the near-total annihilation of the Retribution Alliance coupled with their sense of reverence, quite a number proposed surrendering to the Wandering Alliance and joining them.
