The heroine Su Wan was a carefully cultivated but shady "tool" of the Su family in her previous life. She was brutally silenced after performing a mission for the family. Reborn and returned to the day when she was given as a gift to the Lu family's dandy, she took the initiative to accept this seemingly absurd marriage contract. Using her identity as Mrs. Lu as a cover, she took revenge on the family step by step. On their wedding night, they discovered that the rumored husband Lu Zhanting was actually a top-secret special forces commander. The two began to test each other and cooperate in contracts, and in the process of jointly fighting against external conspiracies (business rivals, hostile forces, and family insiders), they gradually showed their sincerity. Lu Zhanting protects Su Wan in his domineering and passionate way, helping her tear away the family's mask of hypocrisy and regain everything that belongs to her; Su Wan also uses her wisdom and skill to become Lu Zhanting's most suitable partner on the battlefield and in life. In the end, the hypocrites are ruined, the sincere people stay together, family ties are restored through understanding, and love is tempered into gold in the flames of war.
