Geologist Shao Fanchen went deep into Huashan Mountain to explore for germanium deposits. He accidentally triggered the ancient space formation and traveled to Donghua Xuanzhou, the vast Nine Mysterious Realm. Relying on extraordinary geological wisdom (perceiving earth veins, searching for minerals and treasures, and understanding energy flows) and modern thinking, he struggled to survive in this world where martial arts are prosperous, mystical arts are proficient, and hundreds of races abound. From using geological knowledge to work at the bottom, to gradually mastering the method of Yuan Qi cultivation, he combined science and fantasy to embark on a unique path of "Earth Vein Enlightenment". He met like-minded partners (saints, warriors, pharmacists, mechanics), and got involved in dynastic hegemony, sect strife, and ancient secrets. As his strength grew and his vision broadened, he discovered that the Jiuxuan Realm was facing an apocalyptic crisis of depletion of Yuan Qi, as well as the covetousness of evil spirits outside the territory. Shao Fanchen used his profound understanding of earth veins to devote himself to repairing the damaged spiritual veins of heaven and earth, and looking for a way to save the world left by ancient gods and demons. His footprints are all over the Nine Mysterious Continents, uncovering the mystery of the origin of the world, uniting all the heavens and all races, and finally in the final battle that determines the survival of the Nine Mysterious Continents, as an "Earth Walker", he leverages the power of the stars and earth to turn the tide and become a legend. The ending is to choose to protect the new Nine Mysteries, explore the way home, or ascend to a higher dimension, leaving open thinking.
