Among the Daoist Upper Immortals, there is a concept known as the 'Nine Refinements.'
The Inner Realm focuses on refining mana.
The External Realm focuses on tempering the physique.
The Dharma Body Realm focuses on fortifying the Primordial Spirit.
The 'Nine Refinements' is not a literal count, as 'nine' symbolizes the utmost perfection—referring to refining cultivation to its peak.
Within the Daoist Upper Immortals, there is a variety of individuals.
Some dedicate themselves to earnest cultivation.
Yet others pursue extremities.
Some do so due to stagnation in their cultivation, others seek unparalleled strength at the same realm; still, others aim for a solid foundation. During the first three realms of immortality, they often search for secret techniques, expending vast resources to repeatedly refine their mana, physique, and Primordial Spirit in the Inner Realm, External Realm, and Dharma Body Realm.
The Inner Realm's mana becomes more pure.
