Inside the cave, there was utter silence.
The breath of Xuan Yue turned into sparks that floated out, like a gauzy silk brushing past the medicine fields and Qing Hua flowers, falling into the Milky Way formed by the liquefied Spiritual Energy, and then turning into maple leaves that drifted with the waves.
Originally True Fire, now it took the form of wind, then leaves, and finally merged into water.
The apparent sign of becoming an Immortal was transcendence of Heavenly Life, where one's existence no longer bore the concepts of life and death, only the fading of the Dao.
The path of Immortals allowed all methods to transcend form. Fire could become water, water could become fire, with a flip of the hand clouds appear, with a cover of the hand rain falls, manipulating the Heaven and Earth Laws at will.
Thus, mortals cannot defy Immortals, for in the eyes of Immortals, Daoist Skills are but silt.
