The Cultivation Technique breakthrough purified energy, making his soul impervious to external influences.
At least, those of the same realm couldn't impact him, and even cultivators of higher realms struggled to affect him greatly.
Then there's the Cause and Effect Ability, an ability gained after the River of Souls itself advanced.
Similar to the Virtual World, the emergence of Cause and Effect Ability allows the Soul Purifying Sea to connect with others through causality.

Transformation and rebirth have become synonymous with the Lifeless True Saint.
