Han Yi, a young man imprisoned by fate, lives in the shadow of his greedy neighbors. His parents disappeared mysteriously, and the ancient jade passed down from his family was regarded as a treasure by his neighbors. When Han Yi used blood to activate the ancient jade in a desperate situation, a strange space called "Mustard Seed" descended. It is both a golden finger and a curse - Han Yi must travel through the heavens, face the greedy "neighbor" souls in each world, and fulfill their obsessions in order to gain power. He travels through the wasteland, the strange realm, and the fairy world, and each time he encounters different neighbors. They may be sinister or crazy, but they all point to the same mystery: What is the connection between the mustard space and the neighbors? During his gloomy journey, Han Yi used enthusiasm to ignite hope, but the dark truth was gradually swallowing him up. Can he escape the trap of fate? Mustard Seed Space, whose prison is it?
