After the Fourth Prince dies, his soul does not return to the underworld. Instead, he is reborn in the body of his former favorite consort, Nian Shilan. Everything around him is familiar yet strange: his eldest son is alive, Yixiu no longer torments herself, Qi Yuebing is still a master strategist, and there is also his younger self, patient and shrewd.
But life in the prince's household is truly difficult. He had no idea that, as a woman, the slightest misstep could bring disaster! The power struggles and open and covert schemes in the harem are no easier than the political battles at court.
Fighting heaven, the consorts, and the various factions is nothing compared to fighting oneself.
With a different identity, he walks the road of the Nine Princes' succession struggle all over again. This time, he will live life to the fullest, and not even his younger self can stop him... Long live the emperor!
