Qi Guanxue, a modern social animal, died suddenly and traveled through time to become the most unpopular sixth princess of the Great Xia Dynasty. The original owner was born with a weak body, no beauty, and lived cautiously in the deep palace, but eventually became a victim of palace fighting. Qi Guanxue came through time and was bound to a "powerful country system". The system told her that her lifespan and strength were closely related to Daxia's national destiny. The stronger the country's fate, the stronger she will be, and she can even live forever. On the contrary, if the country is destroyed, she will perish. Looking at the mess in front of him, surrounded by powerful enemies outside, corrupt officials inside, and the people living in dire straits, Qi Guan felt numb. In order to survive, she was forced to embark on the path of "building a strong country through infrastructure". Repair water conservancy, modify farm tools, open mines, engage in trade... By the way, we will also take care of those blind princes and sisters. However, as she gradually built Daxia into an unprecedentedly powerful empire, why did the legendary regent, who was decisive in killing and not close to women, look at her more and more wrong?
