Huang Xiaoxiao lives in the Winter Kingdom, a frozen planet where humanity survives only through Fire Crystals and Ability Users. In her previous life, her stubborn refusal to marry led to the deaths of her father and brothers, who perished hunting in a snowstorm, while her mother froze to death searching for them. Huang Xiaoxiao herself died alone from starvation and cold. Upon rebirth, she resolves to change her fate and agrees to marry Zhuo Yi, a scarred Level 5 Ability User whom she previously feared. Her family, desperate for resources, eagerly accepts the match, and Zhuo Yi brings Fire Crystals and meat to her starving household before taking her to his large, warm home.
Zhuo Yi treats Huang Xiaoxiao with unexpected gentleness, drying her hair after her bath and defending her against his younger sister, Zhuo Wenxuan, who looks down on Huang Xiaoxiao as a poor, unattractive commoner. The conflict escalates when Zhuo Wenxuan and her friends discover Huang Xiaoxiao is a Spirit Ability User but mock her as a failure who has never successfully crafted an item. Despite the humiliation, Zhuo Yi remains supportive, insisting he can afford to provide for her regardless of her crafting reputation. Huang Xiaoxiao, however, harbors a secret: in her previous life, she had discovered the key to successful crafting but never applied it. This time, she intends to master her abilities.
Her first attempt at crafting a storage bracelet results in a house fire due to her inability to control the flames, leading neighbors to label her a fool. Undeterred, she discovers that throwing snow on the fire helps regulate the temperature. After several attempts, she successfully creates a bracelet with a one-square-meter storage space. She soon realizes a unique phenomenon: each time she reforges the same item, its storage capacity doubles. By the time she returns home, the bracelet has expanded to over sixty-five thousand square meters, surpassing the world record of ten thousand square meters. She hides this achievement, boasting only to her family that it holds a few hundred thousand square meters, though they dismiss it as exaggeration.
Huang Xiaoxiao continues to refine her skills, forging explosive beads that initially appear weak, earning her the reputation of a useless crafter. However, during a fishing trip at Black Wind Ice River, she demonstrates the true power of her weapons by shattering thick ice that others could not break. When a swarm of dangerous Arrowfish attacks, she uses her powerful explosive beads to repel them, shocking her companions. She also discovers she can store living creatures directly into her spatial bracelet by touching them, allowing her to harvest fish instantly. Despite her growing competence and the protective nature of Zhuo Yi, who silences his friends when they criticize her, Huang Xiaoxiao faces ongoing hostility from Zhuo Wenxuan and societal prejudice. She remains focused on her goal of becoming a top-tier artifact refiner, using her rebirth knowledge to secretly build a powerful foundation while maintaining a modest outward appearance.
