The protagonist Jiang Qingshuang accidentally scattered some of her soul fragments in countless parallel worlds of lower planes due to a high-dimensional energy leakage accident. As a "soul cleaner" reserve for an advanced civilization in the universe, the protagonist is forcibly bound to the "fragment recycling system" created by his original civilization. He embarks on a journey to various small worlds to recycle his soul fragments by experiencing different lives and fulfilling the original owner's wishes. This is not only to maintain the stability of the laws of the universe (to prevent energy fragments from disrupting the order of the lower planes), but also the only way for the protagonist to return to his true form and even further advance his dimension. Every successful recovery of fragments can enhance the understanding of the soul and the laws, and eventually become the framer of the laws of cosmic civilization step by step.
