Classic of Mountains and Seas, I Cultivate Immortality Through External Elixirs

(Traditional immortality writing, new immortality cultivation system, prehistoric mountains and sea background) The way of inner alchemy is to cultivate the essence of the sun and the moon, nourish the essence internally, and store the spirit externally. Once the elixir is completed, the Tao will be achieved. The method of external elixir can seize the creation of heaven and earth, restrain the mountains and seas and strange beasts, refine the beauty of nature, and seize the Tao to become an immortal. I once heard that the Yellow Emperor refined the elixir in Huangshan and became an immortal. Before his ascension, he left a solitary vein and inherited it. Later generations of this lineage will conceive a son, and there is no hope of inheriting this inheritance by cultivating inner elixirs. Find exotic animals from mountains and seas to refine heavenly materials and earthly treasures, and use the method of external elixir to achieve immortality and earthly deity.
