The Little Princess Who Was Reborn as the Barren Emperor's Doomed Daughter

Li Chengxin transmigrated into the body of the little princess who had just died, daughter of Li Mingchong, an emperor with no heirs. She arrived with a System and worked hard to earn more years of life just to survive. To protect his throne, Emperor Mingchong claimed that his consort had given birth to a prince and named the baby crown prince. Then, during a crisis, he turned the crown prince into a princess. Li Chengxin was delighted to grow up as a princess, while also wielding the power of the crown prince. But during another crisis, the System malfunctioned, and the emperor's most capable minister lost his memory. As crisis after crisis unfolded, Emperor Mingchong let slip that he had been reborn. The revelation left the transmigrated Li Chengxin terrified.
