The genius girl Su Xingwan travels to China in the 1960s with her cutting-edge technological knowledge from the 30th century. In an environment where supplies were scarce and technology was backward, she used her astonishing wisdom to promote changes in the times and ignited the fire of hope with the light of science.
When she was 5 years old, she shocked everyone by improving factory machinery with her physics knowledge that was ahead of her time. As a student, she made her own generators, developed water purification devices, and used science and technology to improve people's livelihood. However, she was criticized for "the uselessness of reading" and was fortunately protected by her family. In high school, she formed a scientific research team to break through technical barriers under simple conditions, and met Gu Chenzhou, an educated youth. The two studied side by side under a kerosene lamp, and their love grew secretly.
Gu Chenzhou walked 30 miles to find books for her. When she was questioned about "academic plagiarism", she stayed up all night to handwrite proofs and defend her honor with the simplest scientific logic. Su Xingwan successfully developed a "nano energy storage membrane" and substituted antibiotics, but was reported. Gu Chenzhou teamed up with educated youths to protect her, allowing her to continue her scientific research.
After the college entrance examination resumed, she entered the Chinese Academy of Sciences as the top scholar, and Gu Chenzhou became her assistant. Under the starry sky in Lop Nur, he used experimental equipment to make a ring and proposed. At the wedding, his mentor gave him a collection of physics lecture notes. The eldest brother used the prosthetic limb she invented to cut the cake. The family embraced the future at the dawn of a new era.
