Geologist Shao Fanchen ventures deep into Mount Hua to survey a germanium deposit, but accidentally triggers an ancient spatial array and transmigrates to Donghua Xuanzhou, a vast land in the Nine Profound Realms. Armed with extraordinary geological insight, which lets him sense ley lines, find mineral deposits and treasures, and understand the flow of energy, as well as a modern mindset, he struggles to survive in a world of flourishing martial arts, profound arcane arts, and countless races. From using geological knowledge to get by at the bottom of society to gradually mastering the cultivation of primordial energy, he combines science and fantasy to forge a unique path to enlightenment through the ley lines. He meets like-minded companions, including a saintess, a martial artist, a pharmacist, and an artificer, and gets caught up in dynastic wars, sect rivalries, and ancient secrets. As his strength grows and his horizons widen, he discovers that the Nine Profound Realms face an apocalyptic crisis of dwindling primordial energy, while demonic forces from beyond the realms covet their lands. Drawing on his deep understanding of the ley lines, Shao Fanchen dedicates himself to repairing the damaged spiritual veins of heaven and earth and seeking the ancient gods’ and demons’ method for saving the world. His journey takes him across all nine Profound Continents, where he uncovers the mystery of the world’s origin and unites the myriad races of the heavens. In the ultimate battle that will decide the fate of the Nine Profound Realms, he turns the power of the stars and the earth’s ley lines to the cause, averts disaster, and becomes a legend as the Walker of the Earth. The open ending leaves readers to ponder whether he will protect the newly reborn Nine Profound Realms, seek a way home, or ascend to a higher dimension.
