The soul of Chu Cai, a lover of military history, traveled to Huijiang City of the Great Chu State and became a 13-year-old bastard from a declining family. Lin Qingwan, the daughter of a wealthy Huijiang businessman, broke off her engagement just after time travel. She used the excuse "unless she got the top prize" as an excuse to break off her engagement. The Chu family's former glory became a laughing stock. Faced with the cold eyes of his family and the ridicule of the world, 13-year-old Chu Cai relied on his wisdom from his previous life to study the art of war and the history of war, to deal with it calmly and hide his edge.
