The path of cultivation seeks the ultimate principles of heaven and earth.
The rules of heaven and earth are the manifestation of these ultimate principles.
Only the Primordial Spirit can bear the rules; the Divinity Transformation perceives the rules of heaven and earth. The moment one feels the rules of heaven and earth, there lies the opportunity to ascend into immortality.
Becoming a True Immortal implies a further transformation of the Primordial Spirit, influenced by the chance of ascension, which allows preparing for comprehension and condensation of rules.
Sowing the seed of rules is known as the Dao Seed.
Xiang Wuji has just entered the True Immortal Realm, but he has not even sown a Dao Seed.
Strictly speaking, Xiang Wuji does not qualify as a True Immortal.
However, within the Undefeated Demon Blood, residual partial rules from Mara remain.
