Even those in the True Spirit Realm didn't deliberately strive to enhance the quality of the Great Sun Golden Crow Divine Flame.

It required an immensely vast accumulation to perceive the tiny improvements.
Quantity could lead to a qualitative change, but the amount needed for that qualitative change was enormous.
"Bang!"
