The story begins with an unprecedented drought sweeping across the country. People in the palace are panicked and resources are drastically reduced. The heroine Shen Zhiwei, one of the humblest maids, was framed for discovering the secret of a noble concubine, and was thrown into the cold palace to die together with the deposed and disabled ninth prince Xiao Jin. In a desperate situation, she accidentally activates the "Waste to Treasure" system, which can transform all "waste" - including spoiled meals, dead plants, and even the malice and resentment cast by others - into survival materials and energy points.
