As soon as Shen Qingci, the queen of the investment bank, opened her eyes, she became a humble concubine in the prince's mansion who was about to be sent to celebrate the death of the seventh prince. Faced with a dead end, she calmly took up her pen and changed the engagement contract into a detailed "cooperation contract." The prince Xiao Jue on the hospital bed looked at the familiar sharp edge in the eyes of the woman in front of him and signed his name, but he didn't know that she was the old shadow that he had wronged in his previous life, hated him to the bone, and couldn't get it. From then on, the palace's account book was her plan to break the situation, and the power of the court was her chess game. When Xiao Jue, who had been dormant for several years and finally ascended the throne, found all the evidence pointing to her "betrayal", he once again chose to give up. Three years later, the mysterious "Mr. Jin", the richest man in the south of the Yangtze River and the man who controlled the economic lifeline of the empire, lifted his hood in front of the palace and chuckled at him: "Your Majesty, you are well. This old debt should be settled today with interest."
