In a world where humans and spirit pets coexist, humans form contracts with spirit pets, command them in battle, and forge bonds with them—this is the world of the Spirit Master. Li Changsheng consumes a Creation Fruit, gaining the ability of soul perception, which allows him to perceive spirit pets, spirit pet eggs, and treasures within a certain range. The story features powerful creatures such as the land king Golden Behemoth, the world serpent Jormungandr, the devastating Hundred-Armed Giant, the three-legged Golden Crow embodying the sun, and the Time-Space Dragon that controls day and night.
