In her past life, figure skating Olympic champion Lin Xinjing was reborn back to the age of eight, discovering that her sister was also a reborn person and had chosen the mother first. She resolutely followed her father, formed a new family with the cold-faced stepmother Shen Yun, and embarked on the path of scientific research. Years later, her sister was bullied by teammates in America, suspended, and hit rock bottom, returning home for help. Lin Xinjing, as a Tsinghua-Peking life science PhD, crossed over to serve as a coach, using scientific training to help her sister fight all the way from municipal competitions through national selections and world tours, and finally defeating her arch-rival with the first-ever quadruple Axel jump by a human female in the Winter Olympics arena, winning the gold medal.
