Chu Tianlin, who came from a poor family, married into the Chu family due to family changes. From then on, he was involved in the disputes between wealthy families and the chaos of the Warring States Period. He is restricted everywhere in a wealthy family and seems to be powerless, but in fact he has hidden wisdom and military strategy. As the border war broke out, Tianlin was forced to step forward and became famous on the battlefield with his ingenious strategies. He gradually transformed from a despised son-in-law into a strategic figure who controls the family and military power. In the intertwining of multiple forces, secret fights within families, and life-and-death battles on the battlefield, Tianlin gradually emerges, involving many story lines such as the Su family, the Chu family, the imperial court, and foreign lands. Through the intertwining of force, intelligence and emotion, he not only protects his loved ones, but also achieves his own life value and the righteousness of his family and country. The story goes through family storms, battlefield fighting, power struggles, and finally peace and redemption. Each volume is both independent and interlocking, forming a realistic and rigorous picture of the grand life of the God of War's son-in-law.
