Shen Nian, a graduate student in materials science at the National University of Defense Technology, wakes up and transforms into a foster girl in a military compound in the 1950s.
Her adoptive mother forced her to marry a widower in exchange for a bride price, and her adopted sister took away her place in the college entrance examination.
Fortunately, she was bound to the nanomaterial synthesis space.
Cold-resistant fibers, bulletproof ceramics, thermal barrier coatings... Time and again, she "anonymously" sent materials that transcended the times to the front line.
The file codenamed "Carrier Pigeon" was circulated among the top management, and there was a place in the merit book of two bombs and one satellite that she could not sign.
Special operations company commander Zhou Weidong was ordered to "assist in scientific research and defense," but he moved his heart while guarding day and night:
"Shen Nian, you have built so many things for the country, can you... Also build me a home?"
She handed herself over to the country, but unexpectedly, the country also handed someone over to her.
