There was no harmony among the Primordial.
Based on the existing clues, it is inferred that on the Ancestor Star of the Ancient God Clan, the You Ying God likely held the advantage, as it was the first to attempt completing the Third Law.
And the rules on the Ancestor Star seemed to lean towards it.
From then on, the Ancient God Clan understood the importance of the Third Power.
This was probably discovered by Qilin Venerable through researching himself.
Qilin and Qiongqi are products of the Third Power, but unfortunately did not achieve perfect evolution.
Understandably so, if the Primordial realized the sacrifices they created actually had the power to backlash against themselves, they would naturally try every possible means to make them flawed.
