Gu Mingli and Gu Mingyue, a brother and sister, accidentally cross over into ancient times, becoming the son and daughter of the current prime minister, and the two accidentally bind to a misplaced system. The sister, possessing a financial mind, shoulders the task of widely scattering savings, and must spend all family wealth to protect herself; the brother, coming from a science and engineering background, shoulders the mission of family stability, and has no choice but to constantly accompany the monarch and win the monarch's appreciation. The brother and sister's father is good at managing industries, and the family's savings are abundant, continuously acquiring property and wealth. The brother and sister have no choice but to widely recruit commoners, build roads, and help wild refugees to consume family wealth, but the family's assets instead accumulate more and more, and the brother and sister sigh helplessly, Father, please do not expand the family business anymore, we really cannot finish spending it.
