Abandoned in the bitter winter cold, baby Xu Nian'an is discovered by Xu Dachuan and Xu Hongmei, who immediately report the case to the police. After the local police station verifies that she was abandoned, they legally register her household and adopt her. Although the couple struggles financially, they do everything they can to support her education. Her adoptive father encourages her to overcome her inferiority complex with the idea of 'leveling up by fighting monsters with five spiritual roots.' Through diligent study, Xu Nian'an makes a remarkable comeback and becomes the province's top scorer in the college entrance examination. Just then, her biological mother, who abandoned her years earlier, appears on television, falsely claiming to have spent 18 years searching for her daughter and inciting online harassment to force Xu Nian'an to acknowledge her. Xu Nian'an produces the original police report to expose the lie and firmly chooses the adoptive parents who raised her for eighteen years as she sets off for a new life at university.
