Why Can't I, the Queen Mother, Have the Power to Dominate the World?

I traveled through time and became a fake eunuch, and I was forced to become the "medicine guide" for the Queen Mother. She used my body to relieve the pain of the poison, and I relied on her power to become a great minister. We are our most dangerous allies and our closest lovers. When I wanted to retire and marry her, the Queen Mother tore off her cold mask, her phoenix eyes filled with evil and resentment. "Jiang Yu, you only belong to me! If you dare to marry another woman, I will kill her among the nine tribes! Unless, I am big and she is small!"
