"Sacrifice For The Race"
After all, resources were scarce in this world and usually, only when the previous six-winged celestial died could there be another six-winged celestial.
The queen's six wings were a little different because, to be honest...her whole wings were golden instead of white!
But she used a special trick to dye her wings white and only let a few lines of gold to stand out because the previous kings and queens also had these thin golden lines on their wings.
Still, so far, no kings and queens in this world had fully golden wings, not even the first celestial king in this world.
The first celestial king in this world could be called as the third or the fourth if counting the first three generations of celestials who had left this world for a higher-level world.
Only those three generations have celestials with fully golden wings, and yet, even in the higher-level world, the descendants of the celestials rarely had this kind of fully golden wings.
