A Primordial Heavenly Stone flies in from beyond the Great Firmament. The Grand Supreme Elder Lord places it in the Eight Trigrams Furnace to be refined, but an accident occurs, and the energy released by the stone breaks through the barrier. The stone eventually falls into the mortal world, takes on a physical form, and begins a legendary journey. Tian Yu is born with divine strength. Though his meridians are blocked and he cannot cultivate, after enduring life and death, his cultivation progresses at astonishing speed, and he ultimately attains the Primordial Unity. There are spells, magical treasures, elixirs, and formations of every kind. Immortals, humans, demons, and devils pit their wits against one another, while schemes and intrigues emerge one after another. The plot unfolds in tightly linked turns, full of humor and comedy as well as tension and thrills. They fight for life and death, part forever, and rely on one another through it all. There is passionate romance, as well as the defense of order across the three realms. In the end, good and evil, black and white: the Dao gives birth to all things, and all methods return to one.
