Shen Yan, the surviving son of the Marquis of Zhenbei, was burdened with the grievances of his family and hundreds of thousands of Yanmen border troops. He hid in the capital with his old subordinates Wei Zheng and Lin Zhou, pretending to be an inkstone maker from a poor family, using the inkstone museum as a cover to secretly collect evidence of the traitor Qin Song. When they first met Yun Shuwan, the daughter of the former censor, they both came here to avenge their grievances. After testing each other, they formed an alliance and joined hands in planning. Shen Yan got acquainted with the seventh prince Xiao Chengyu, and with the secret help of the eldest princess Xiao Qingyuan, she contacted the old Shuangtian Pavilion and Taifu Liu Bingqian to gradually build an anti-Qin force. Qin Song sensed the threat and repeatedly tested, suppressed, and even sent people to assassinate him. Shen Yan and others responded calmly, alienating the relationship between Qin Song and the prince Xiao Chengze, and gradually obtained evidence that Qin Song was corrupt, collaborated with the enemy, and secretly transferred the imperial army. Xiao Chengyu went to the border to supervise armaments and look for evidence of collaboration with the enemy. Shen Yan stayed in Beijing to stabilize the layout, resolve food shortages, eliminate traitors, and gradually reduce Qin Song's power. Qin Song jumped over the wall to initiate a palace coup. Shen Yan, together with Wei Zheng, Liu Bingqian and others, mobilized Shuangtian Pavilion and the Gyeonggi garrison to intercept, successfully captured Qin Song and deposed the prince. In the court hall, Duke Shen Yan revealed all the evidence of Qin Song's crimes and cleared up the grievances between Zhenbei Hou Mansion and Yanmen.
