The heroine Shang Xian is reborn as Xi Min, an agent of the Wugou Division. As soon as she is reborn, she learns that the strong General Dingyuan suddenly fell ill and died of a sudden illness. When Min Xi investigates the cause of General Dingyuan's death, he accidentally discovers that the man who murdered the Shang family was actually the just Lu Shangshu. At the same time, the male protagonist Wu Laizhuo is also secretly investigating the case of the Shang family being wiped out. The two are enemies of each other and will never get to know each other without fighting. During the investigation, Xi Min used the exclusive clue-grabbing method taught to her by her father to lead to Lu Shangshu, the master behind the Shang family's extermination case. Wu Quzhuo therefore looked at Xi Min with admiration and secretly liked Xi Min. Xi Min and Wu Quzhuo teamed up to collect evidence of Lu Shangshu's murder of the Shang family, exposed Lu Shangshu's true face, and vindicated the injustice of the Shang family. After Lu Shangshu went offline, Xi Min discovered that the real reason why the Lu family murdered the Shang family was to cover up the involvement of the eldest son of Lu in the rebellion of King Huainan of Jingguo. When the war broke out, Xi Min stayed in the capital to further investigate the rebellion and uncovered the mastermind, King Huainan, and his cronies. On the battlefield, Wu Quzhuo's army defeated the King of Huainan. The two cooperated internally and externally to relieve the crisis in the Chongqing Kingdom and save the people of the two countries from the disaster of war. To bring peace to the world, Xi Min and Wu Quzhuo broke through the last layer of window paper and came together.
