After collapsing from overwork, modern office worker Qin Yuchen unexpectedly transmigrates to the Hunan Governor's Mansion in 1920, during the Republic of China era. He becomes Qin Chaoyang's eldest son, a young marshal who shares his name. The original Qin Yuchen began training in martial arts at Wudang from childhood. His skills are unfathomable, and he also studied military affairs in Germany, making him a rare all-around talent in the chaotic Republic of China.
