Heavenly Craft and Hidden Mysteries

Beneath the surface of the modern city, the hidden traditions of the Xuanmen and the Mohists have waged a shadow war for a thousand years. Lu Yan, owner of a repair shop in an urban village, specializes in old objects that "can't be fixed." In truth, he is the last inheritor of the Mohist Juzi lineage. He possesses a fragment of The Nine Chapters of Heavenly Craft, and his left eye can see the "Heavenly Craft patterns" through which energy flows.

He gradually discovers that Earth itself is a vessel for life, built in ancient times by a Mohist Juzi according to the blueprints of The Nine Chapters of Heavenly Craft. The so-called paranormal incidents are merely "system malfunctions" in a machine that has been running for thousands of years. Before his master died, he left behind two final words: "The Heavenly Craft creation won't hold much longer" and "Don't trust the Xuanmen." Meanwhile, the Xuanmen leader, "Number Zero," who claims to be the System administrator, and the "Rebooters" all have their own agendas, while the nine chapters lie scattered across the land.

Lu Yan joins forces with Shen Qingwu, a diviner of the Xuanmen, after a thousand years of enmity between their lineages. Together, they pursue the ultimate secret of the Heavenly Craft creation, until they must face the question his master left behind: Should they repair it, or tear it apart with their own hands?
