In the seventeenth year of Lintai, the undercurrent of checks and balances in the six regions was surging. Suxi Liu Tianluo was responsible for trade and the important responsibilities of his family and country. He first went to Canglan Pass to sign a five-year truce with General Yu Ze of Lintai, and then infiltrated into Taichang Imperial City under the alias Su Luo to open a silk and satin shop, using the trading house as a secret line to gather power. Pan Qi, the second prince of the Qi Kingdom, fell in love with her and secretly exchanged information with each other as bargaining chips; Fu Shuman, the princess of the governor of Ming, was obsessed with Yu Ze and set up troubles many times out of jealousy; and her husband, the princess Yu Ning, hid in hiding and plotted secretly. During a blizzard, Shuman set a trap. Liu Tianluo and Yu Ze accidentally fell into a valley and were trapped in a desert cellar. In the desperate situation, the two put aside their suspicions and looked after each other. The tit-for-tat game in the past gave birth to a subtle tenderness. The various forces in the imperial city are intertwined, and the chess game of marriage, the ambitions of various countries, and the obsession of children are intertwined. Under a brief period of peace, the foreshadowing of strife sweeping the world has already been laid. Everyone is an involuntary pawn in this twenty-year conspiracy.
