At the end of the Yan Dynasty, Lin Ce, a soldier in the frontier army, died on the battlefield due to corruption in his family and an ambush by the enemy. He was reborn into the early morning when he had just joined the frontier army ten years ago. Relying on the memory of his past life, he saw through the ambush of the Beidi Pioneers in advance, beheaded the enemy general with one sword, and established his authority in the military camp. After that, he used the information gap to predict the war trend, break the suppression of the clan, win over the people, and was promoted step by step to the general of the border town. He not only repelled several invasions of Beidi, but also overthrew the corrupt clan, unified the military power of the border army, and finally became the "god of war" protecting Dayan, rewriting the destiny of himself and the country.
