Shi Feiyang decided not to destroy the Demon Sword, firstly because it reminded him of his own bitter past as an outcast, feeling a deep empathy, and secondly because of the Earth Evil 72 Transformations.
The metaphysical is called Dao, the physical is called a tool.
Innate Dao Body is the basis, Acquired Skill is the application, Immortal Cultivation seeks the Innate, aiming for eternal life, but Immortals are not just merely existing and living like minerals and plants.
One must harness the Innate and employ the Acquired, grasp the great Dao and generate All Techniques. It is only when Innate gives rise to Acquired that life is called, and Dao can only exert its effect through skills.
Merely emphasizing the Innate over the Acquired, and the great Dao over skills, would only lead to lofty ideals without practical skills, living in a fantasy detached from reality.
