In the ancient Star Dome Realm, formed from the Ninefold Heavenly Palaces, Eighteen Netherworld Courts, and Thirty-Six Grotto Heavens, the cultivation civilizations of the Hundred Schools of Thought flourish, yet remain under constant threat from the chaotic energy of the Sea of Chaos.
On the night the Chu family of Qingzhou City is wiped out, the mysterious youth Chu Xiao, who possesses the "Void Profound Dao Body," is swept into a rift in time and space by a mysterious bronze mirror. After experiencing twelve lifetimes of reincarnation within the Reincarnation Mirror, he awakens. He then wanders into a Mohist city of mechanisms and unlocks the cultivation system known as the "Profound Blueprint of Mohist Mechanisms." When a planar tide erupts, he awakens the "Warrior School's Battle Qi" and discovers a projection of a parallel universe within a rift in the Sea of Chaos.
As the story unfolds, Chu Xiao transmigrates through the Six Heavenly Abysses, adventuring across different universes and encountering tangled webs of karma and battles over the Daoist lineages. He also discovers that the founders of the Hundred Schools of Thought are all projections of the same being. He must face not only Chaos Devourers and the embodiment of Chaos itself, but also unknown challenges brought by higher-dimensional "Observers."
Along his path of cultivation, Chu Xiao uses his unique constitution to cultivate six systems at once, fighting alongside companions such as the Warrior School successor Nangong Xuan and the Mohist mechanism genius Mo Qingyuan. In the end, he fuses the six systems into the "Primordial Dao Canon," crosses the ultimate Heavenly Abyss, and confronts the mysteries of creation. Meanwhile, the heroines each take charge of a universe, leaving readers with an open ending full of possibility.
