The modern girl Xin Yi dies unexpectedly, and her soul travels to a parallel universe as an orphan girl from the Northern Wei Dynasty. This world strictly reproduces the era framework of the official history "Book of Wei" and "History of the North". Historical events, war nodes, and social systems are completely consistent. Only individual destiny, folk rumors, and minor encounters have deviations. Living in troubled times, the village has been repeatedly devastated by wars, leaving only ten young men alive. A new round of strict conscription was suddenly issued. The adoptive father in the family is old and frail and will die on the battlefield. In order to protect his loved ones and protect his family, Xin Yi decided to join the army for his father, and Ahe, his best friend from the same village, also joined the army. The two disguised themselves as teenagers and entered the brutal military camp, where they faced bullying, strife, life-and-death battles, and the death penalty crisis of exposing their identities. Xin Yi used modern people's calm thinking and ability to survive in desperate situations, repeatedly breaking out of danger, accumulating military exploits on the battlefield, and rising steadily. He gradually realized that his destiny echoed the thousand-year legend of "General Xiaolie". She broke free from the shackles of the times and was not afraid of the prejudices of the powerful. In the end, after her meritorious service in the war, she was indifferent to fame and returned to her hometown calmly. With her loyalty and perseverance as a daughter, she achieved a period of filial piety in troubled times that is remembered by both official history and legend.
The intention: not to establish one's life based on love, but to survive with perseverance, to guard the family with loyalty, and to break the situation with one's own heart. It interprets the filial and filial character of ordinary little people in the established historical torrent, unwilling to accept fate as a piece of cake, and goes against the will of heaven to rewrite their fate. It extols the core of female independence, two-way redemption, and growth in troubled times.
