In his previous life, Su Yunjian was a chess piece sent to the palace by the Prime Minister. He was promoted from a talented man to a queen, but due to the downfall of his family, he was deposed from the palace and died with hatred. Reborn and returned to the night before she was deposed, she no longer held back and actively sought to break the situation. By chance, she rescued Shen Rong, the leader of the "Tiance Gang", the largest force in the world, who was being hunted. Shen Rong was once a famous border general, but he was forced to leave the army due to the strife in the palace. The two reached an agreement: Su Yunjian used her wisdom and connections in the palace to help Shen Rong investigate old cases and expand his power; Shen Rong used force as a shield to help her escape from the control of the imperial power. They used the south of the Yangtze River as a chessboard, starting with commercial warfare, salt and iron, and water transportation, to gradually dismantle the enemy's forces and establish a kingdom of rivers and lakes that could rival the imperial court. In the process, Su Yunjian became Shen Rong's "strategist" with his quiet and tenacious demeanor, and Shen Rong cleared the way for her with absolute force and loyalty. When the emperor realized that the lost queen had become a serious problem, it was too late. The two went from being partners in an alliance to partners with interdependent souls, and eventually worked together to pacify the border and clear up the government and the opposition. Su Yunjian came to the court with the respect of "a king who stands side by side", and Shen Rong took off his military uniform for her and managed the country together.
