Starting as a Fake Eunuch: Building a Millennium Dynasty

Su Mu transmigrates into the Great Xia dynasty only to be packaged off to the imperial palace by his own mother to serve as a fake eunuch. Her reasoning is shocking: the Emperor has been rendered infertile by his martial arts cultivation, and Su Mu’s cousin, a favored Imperial Consort, desperately needs an heir to secure the position of Crown Prince. With the entire family's ancestral hopes resting on his vitality, Su Mu intends to keep a low profile and develop quietly. However, immediately upon entering the palace gates, he is publicly intercepted by Li Qingge, the immensely powerful Eldest Princess who holds sway over the court. Afflicted by a severe cold poison, she requires a man with a Pure Yang constitution as a medicinal catalyst. At this critical juncture, Su Mu awakens the Ultimate Family Prosperity System. He instantly acquires the divine skill "One Shot, One Soul," guaranteeing a one hundred percent conception rate, and unlocks the Pure Yang Sacred Body, which allows him to grow stronger and absorb cultivation bases through intimacy. After a single night, the princess's poison is completely dispelled, and Su Mu advances directly to the Grandmaster realm. From then on, he thrives within the inner palace. His Imperial Consort cousin eagerly awaits her turn, while a foreign princess insists he promised to admire the moon with her instead. Years later, looking upon a court filled with royal heirs, the Emperor passes away with a contented smile, finally assured that his lineage will endure.
