A Level 4 Extraordinary undergoes a single Life Essence Transition.
However, a Fourth-Level Sage, in addition to undergoing a Life Essence Transition, has also comprehended laws and resonates with the World's Will.
In the Human Immortal Martial Path of this world, the Hollow Void Stage corresponds to a level beyond the Level 4 Extraordinary, but it hasn't reached the level of a Fourth-Level Sage.
The Hollow Void Stage understands the reality's dynamics, comprehends the rules, but does not resonate with the World's Will - that is, the Heavenly Dao of this world.
Starting from the theory of Human Immortal Martial Path, Link believes that the God Seeing Realm is about gaining clarity of self, adhering to the natural laws, resonating with the Heavenly Dao, and transforming the realm into an Inner View.
In other words, forming a miniature universe within oneself.
Li Shuwen became more excited as he carefully listened to Link's so-called shallow views.
