Hundreds of thousands of years after civilization's downfall, the world has become a post-technological wasteland occupied by humanoid tribes. The fragile peace among them is endangered by the reappearance of Wushen, a malevolent shape-shifting ghost born from modern technology, who seeks to subjugate the entire population.
Zhuma, a ten-year-old girl, serves as the story's heroine, accompanied by Zhanggong, her lion-like Tibetan Mastiff. Chosen and aided by an ethereal goddess, she must gather a group of allies from the surviving tribes to confront Wushen and prevent him from seizing control of an ancient power.
