Prequel to God of the Seven Realms

[Traditional fantasy + not mindless + slow rhythm] [Qi training, foundation building, golden elixir, Yuanying, and the realm of transformation] [God world, heaven world, human world, ghost world, demon world, demon world] One thought can break all laws, one eye can lock the seven worlds, one sword can rule the world, one person is eternity. This is the supreme being in myths and legends. It possesses supreme power and wisdom, transcends the mortal constraints of mortals, dominates the order of the universe, is eternal, independent of time, and has become a legendary god.
