Ling Han, the Northern King of Great Yan, was framed by his younger brother Ling Xuan and the emperor, and was accused of collaborating with the enemy and treason. After being punished by Ling Chi, he was reborn and returned to the ruined temple where he was exiled three years ago. After his rebirth, he was bound to the "God of War Recovery System" and gained abilities such as martial arts insights and military strategies from his previous life.
Ling Han first rescued his sister-in-law Su Yu'er who was besieged by bandits (actually disguised as Li Hu, the son of the Minister of Civil Affairs), and then received an order to restore his clan status, but was appointed to the Beihuang Camp from the ninth rank to join the army. He delivered medicine to his wife Su Qingyi who was suffering from hemoptysis outside the Su Mansion, and subdued the scout camp at the Beihuang Camp, winning the support of the soldiers with his strength and courage.
At the court, Ling Han exposed the conspiracy of Li Wenbo, the Minister of Civil Affairs, to steal military rations, and was promoted to captain. Later, he foiled the assassination of the "Ghost Shadow" killer sent by Ling Xuan, and produced irrefutable evidence to put Ling Xuan under house arrest. The Beidi army broke through and invaded. No one in the civil and military dynasties dared to fight. Ling Han took the initiative to ask for orders to go out and was awarded the title of "General of Rebellion". Before leaving, he bid farewell to Su Qingyi and unexpectedly discovered that the notes left by his father contained a surprise attack route to the North that was consistent with the system's deduction. He had deep questions about Su Qingyi's life experience, and then rushed to the North with his commander's seal.
