The supreme prince of the Spirit Realm falls victim to a plot and is killed, then returns in the mortal world as a humble servant. He holds a matchless creation elixir and extraordinary cultivation techniques, and with only a rusted blade he sets out to upend the martial world. Two martial souls awaken in him at once. His journey leads through the Heavenly Demon Treasury, the Dragon Transformation Realm and ancient ruins, where he claims treasures such as the Demon Lord Armor and the Great Desolate Mirror, and a dragon soul and a spirit dog come under his command. Gifted rivals, parasitic sect members and evil races from beyond the world all come for him, while he protects the friends and family he loves and climbs through the martial ranks. Two archenemies, Long Zhetian and Nangong Lingtian, stand in his way, tied to a conspiracy buried since an ancient age of darkness. The result is an action fantasy adventure built on cultivation battles.
