The protagonist of this series is the young deer Deer, a descendant of the Nine-Colored Deer King. His parents, the Deer King and Queen of the "Spiritwood Realm," have been imprisoned long-term by the gluttonous Da Dawang, who forces them to provide him with Deer King energy. To make matters worse, Da Dawang has dispatched the fierce gluttonous warrior Wang Daming to capture Deer and eliminate this potential threat. The young Deer is determined to accept the challenge and his destiny—to rescue his parents and defend his homeland. Accompanied and aided by five realm emissaries, Deer embarks on a arduous journey across five realms, gaining unique powers along the way. After enduring a series of trials and setbacks, and with the help of friends and other spirits, he acquires the energies of the five elements: metal, wood, water, fire, and earth. Ultimately, he arrives at the Gold-Iron Realm, defeats Da Dawang, and rescues his parents.
