Chen Wan was admitted to Tsinghua and Peking University at eighteen. As her mother lay critically ill, she learned the cruel truth: back then, her mother's university admission letter was torn up by her father and maternal grandfather, causing her to miss her chance at education and suffer hardships throughout her life. After her mother passed away, Chen Wan bound herself to the Top Scholar System, traveled back in time to 1980, and transformed into a system to accompany the young Lin Guizhi in defying fate and changing her life. Facing forced marriage, imprisonment, and endless suppression, Lin Guizhi endured the hardships, relied on her left hand to take the college entrance examination, won the top female science scholar, and successfully entered Tsinghua and Peking University. She traveled far to the vast desert to devote herself to scientific research, became a pillar of the country, and gave back to her hometown. As destiny was rewritten, Chen Wan gradually faded away, quietly awaiting a reunion with her mother once again.
