This is why, when Primordial Heavenly Sovereign does things, he often leaves people puzzled. Some things he does have good intentions, but when implemented, he tends to spoil them.
Such is the nature of someone with a twisted personality.
The Saint of Taiqing noticed Primordial Heavenly Sovereign's issues, worried that he would be increasingly affected by the Evil Corpse and risk being bewitched, and thus often stayed close to him, attempting to compensate for Primordial Heavenly Sovereign's character flaws with his own heartless mindset.
This is why among the Sanqing, the Saint of Taiqing was closest to Primordial Heavenly Sovereign—because Primordial Heavenly Sovereign truly had issues.
With two younger brothers, one without issues and one with, the mentally sound Saint of Taiqing naturally chose to help the one with issues.
