Genius Su Xingwan brings cutting-edge scientific knowledge from the 30th century as she transmigrates to China in the 1960s. In an era of scarcity and backward technology, she uses her extraordinary intelligence to drive change and kindle hope with the light of science.
At five, she uses physics far ahead of its time to improve factory machinery, leaving everyone astonished. As a student, she builds a generator and develops a water-purification device, using technology to improve people's lives. But she faces a backlash from those who claim there is no point in studying, and is fortunate to have her family's protection. In high school, she forms a research team and breaks through technical barriers despite their primitive resources. There, she meets educated youth Gu Chenzhou, and the two grow close as they work side by side beneath the light of a kerosene lamp.
Gu Chenzhou walks thirty li to find books for her. When she is accused of “academic plagiarism,” he spends the entire night handwriting proof in her defense, using the simplest scientific logic to protect her reputation. Su Xingwan successfully develops a “nanotech energy-storage film” and an antibiotic substitute, but someone reports her. Gu Chenzhou and the other educated youths rally to protect her, allowing her to continue her research.
When the college entrance exams are reinstated, she enters the Chinese Academy of Sciences as the top scorer, with Gu Chenzhou as her assistant. Beneath the starry sky of Lop Nur, he crafts a ring from laboratory equipment and proposes. At their wedding, her mentor gives her a treasured set of physics lecture notes, her eldest brother uses the prosthetic limb she invented to cut the cake, and the family embraces the future in the dawn of a new era.
