Chu Sheng was originally a illustrious god of war on the frontier. He was framed due to a power struggle and his entire family was raided. He himself was also forcibly sentenced to "bring-in-law". To make up for his mistakes, he was assigned to marry into the Wu family, a business family. Due to the decline of their family business, the Wu family regards marriage as the vitality of the family, while Chu Sheng hides his past and suffers cold shoulder and misunderstanding. The family and country are in turmoil due to external strife, and the family is worried about overt and covert internal conflicts. While using excellent strategies to protect his people step by step, Chu Sheng secretly pursued the truth and worked tirelessly to prove himself. At the same time, he faced multiple hidden threads intertwined with power, money, and emotions, and made difficult choices between personal dignity and collective responsibility. As powerful ministers, political opponents and even old minions appeared one after another, Chu Sheng gradually unraveled the conspiracy under the competition between various forces, realized self-redemption and the rise of his family, and finally stood up for the country's crisis, letting his fate be closely bound to the survival of his family and country - eventually becoming a legend of a generation.
