The Grand Imperial Consort of Great Qi

After transmigrating, a killer becomes a peasant girl. After saving someone, the peasant girl becomes an imperial consort. To her, the enormous imperial palace is merely a tiny patch of land, no different from anywhere else. There are countless beauties in the inner palace, and she is merely one flower among ten thousand. Being a nobody is not so bad! Occasionally competing with them, or watching them fight until they are battered and bloodied over that Son of Heaven, is rather entertaining too. After all, life is far too dull! With the System, she has more than enough ability to protect herself and need not fear being framed. Before she knows it, she has gone from a low-ranking palace woman to an Imperial Noble Consort. What is she supposed to do? P.S. This Da Qi is not that Da Qi. This is a fictional setting. I am terrible at history, so please do not take it too seriously!
