On her wedding day, Shen Ruojin, a tiger daughter of a general, was betrayed by her fiancé Pei Jing who eloped with her concubine. In front of a room full of guests, she resolutely chose to marry Qin Lang, a well-known dandy in the capital. No one knows that Shen Ruojin has been reborn and returned, carrying with him the memory of being betrayed by his family and lover in his previous life, and ultimately his family was destroyed. She originally planned to make a three-part agreement with Qin Lang and reconcile after a year, but she unexpectedly discovered that this apparently dissolute husband was hiding a secret. He not only stood up for her when she was suffering, but also planned strategies when she was on the battlefield. When Shen Ruojin tried to fulfill the agreement with Li, Qin Lang handed the military talisman and jade seal into her hands, vowing to help her win the world. In troubled times, this couple who had been ridiculed worked hand in hand. One held a gun to guard the country, and the other held power to determine the outcome of the government. In the end, they wrote a legend of "the spring is deep in the brocade tent, and the world belongs to you".
