A hundred years ago, human beings were greedy for endless things, plundering mountains and rivers, and slaughtering living beings, which eventually caused evil thoughts in people's hearts to cause disasters. Gray fog envelopes the earth, vegetation is distorted, water and soil are poisonous and rotten, and weak creatures remain resentful.
Lin Yan, a girl from a slum, joins a high-risk cleaning team in order to survive, but gradually discovers that what she cleans is never the wasteland, but the greed, indifference and obsession deep in the human heart.
When the truth about the wasteland is revealed layer by layer, she has to face not only deformed monsters, but also a human world trapped by greed and lies.
Purpose: Tell the story of a girl from the bottom of the world who gradually grows up, explores the truth, and eliminates people's obsessions in the wasteland world, and expresses her thoughts on greed, apathy, ecological destruction, and the redemption of human nature.
